Devices that help children control their diabetes and lead fuller lives may also give them contact dermatitis, report the authors of a new study that calls for mandatory labeling of ingredients for allergy patch testing.

“A high share of patients showed positive reactions to isobornyl acrylate adhesive (IBOA) and/or their medical devices (insulin pumps or glucose devices),” the study authors write in Contact Dermatitis. “A third of patients showed positive reactions to benzoyl peroxide (BP),” used in adhesives.

“The presence of additional unidentified allergens cannot be excluded,” they add. “Overall, our experience once more highlights the importance of having access to a full description of the chemical composition of diabetes devices and related medical devices to efficiently manage patients (including children) who experience adverse skin reactions from such devices.”

Lead study author Catarina Alves da Silva, MD, of the department of dermatology and venereology of Aarhus (Denmark) University Hospital, and her colleagues conducted a retrospective study of 15 referred patients younger than 18 years who had type 1 diabetes. The children were patch tested in the university’s dermatology clinic between 2018 and 2020 in a study of skin reactions linked with diabetes devices.
 

Contact dermatitis from device-related allergens may be common

Many children in the study reacted to chemical compounds related to their devices.

• Of the 15 patients, seven showed positive patch test reactions to IBOA, and five showed positive reactions to BP.
• Ten children had positive patch test reactions to materials from glucose sensors and insulin pumps.
• Three showed positive reactions to adhesive remover wipes.
• Five reacted to .

Marcia Hogeling, MD, a pediatric dermatologist at UCLA Health in Santa Monica, Calif., told this news organization that she expected acrylates to cause problems but was surprised that BP caused positive patch test reactions.

BP is known to be a strong irritant but a weak allergen, the authors wrote.

“It was important to identify the allergens in these devices. Hopefully, this information will be used by manufacturers to create safer products for patients,” Dr. Hogeling, who was not involved in the study, said in an email.

Dr. Hogeling acknowledged that the small sample size is a weakness of the study, although she added that the findings may help providers select devices that do not contain their patients’ contact allergens.

Ryan J. McDonough, DO, a pediatric endocrinologist and the codirector of the Diabetes Center at Children’s Mercy Kansas City (Mo.), said in an email that, despite the small sample size, the study “highlights important device-related experiences of those living with type 1 diabetes that clinicians often encounter.

“We often spend considerable time aiding patients and their families in finding ways to mitigate the reactions,” he explained. “Having a broader understanding of these chemical compositions would help clinicians choose the right devices for their patients and prevent and treat these types of reactions.”

Dr. McDonough, who was not involved in the study, noted that the patients were in Denmark, and they were able to easily transition between insulin pumps and glucose monitoring devices.

“In the U.S., it is often more challenging to switch between devices, due to insurance-related concerns.

“The true rates of reaction in the broad type 1 diabetes population are difficult to assess,” Dr. McDonough said. “The study participants were drawn from patients referred to a dermatology clinic for evaluation of reaction. Many patients either don’t develop reactions or are treated for mild symptoms locally by their endocrinologists.

“This study should serve as a call to action for continued improvements in the transparency of the components that make up the devices and adhesives, and it can provide an opportunity to develop additional interventions to prevent these reactions,” he advised.

No information regarding funding for the study was provided. The authors, Dr. Hogeling, and Dr. McDonough reported no relevant financial relationships.

Republican and Democratic members of the House called for changes in how insurer-run Medicare plans manage the prior authorization process, following testimony from a federal watchdog organization about improper denials of payment for care.

About 18% of payment denials in a sample examined by the Office of Inspector General (OIG) of the Department of Health and Human Services (HHS) either met Medicare coverage rules or the rules of the insurance plan.

As such, they should not have been denied, according to the OIG. That was the finding of an April OIG report, based on a sample of 2019 denials from large insurer-run Medicare plans.

Erin Bliss, an assistant inspector general with the OIG, appeared as a witness at a June 28 Energy and Commerce Subcommittee on Oversight and Investigations hearing to discuss this investigation and other issues with prior authorization and insurer-run Medicare, also known as the Advantage plans.

Most of these payment denials of appropriate services were due to human error during manual claims-processing reviews, Ms. Bliss told the subcommittee, such as overlooking a document, and to system processing errors, such as a Medicare insurance plan failing to program or update a system correctly.

In many cases, these denials were reversed, but patient care was still disrupted and clinicians lost time chasing clearances for services that plans already had covered, Ms. Bliss said in her testimony.

The April report was not the OIG’s first look into concerns about insurer-run plans inappropriately denying care through prior authorizations. The OIG in 2018 reported that insurer-run Medicare plans overturned 75% of their own denials during 2014-2016 when patients and clinicians appealed these decisions, overturning approximately 216,000 denials each year.

‘Numerous hoops’ unnecessary for doctors, patients

Lawmakers at the hearing supported the idea of the need for prior authorization as a screening tool to prevent unneeded care.

But they chided insurance companies for their execution of this process, with clinicians and patients often frustrated by complex steps needed. Medicare Advantage plans sometimes require prior authorization for “relatively standard medical services,” said Subcommittee on Oversight and Investigations Chair Diana DeGette (D-Colo.).

“Our seniors and their doctors should not be required to jump through numerous hoops to ensure coverage for straightforward and medically necessary procedures,” Rep. DeGette said.

Several lawmakers spoke at the hearing about the need for changes to prior authorization, including calling for action on a pending bill intended to compel insurers to streamline the review process. The Improving Seniors’ Timely Access to Care Act of 2021 already has attracted more than 300 bipartisan sponsors. A companion Senate bill has more than 30 sponsors.

The bill’s aim is to shift this process away from faxes and phone calls while also encouraging plans to adhere to evidence-based medical guidelines in consultation with physicians. The bill calls for the establishment of an electronic prior authorization program that could issue real-time decisions.

“The result will be less administrative burden for providers and more information in the hands of patients. It will allow more patients to receive care when they need it, reducing the likelihood of additional, often more severe complications,” said Rep. Larry Bucshon, MD, (R-Ind.) who is among the active sponsors of the bill.

“In the long term, I believe it would also result in cost savings for the health care system at large by identifying problems earlier and getting them treated before their patients have more complications,” Rep. Bucshon added.
 

Finding ‘room for improvement’ for prior authorizations

There’s strong bipartisan support in Congress for insurer-run Medicare, which has grown by 10% per year over the last several years and has doubled since 2010, according to the Medicare Payment Advisory Commission (MedPAC). About 27 million people are now enrolled in these plans.

But for that reason, insurer-run Medicare may also need more careful watching, lawmakers made clear at the hearing.

“We’ve heard quite a bit of evidence today that there is room for improvement,” said Rep. Bucshon, a strong supporter of insurer-run Medicare, which can offer patients added benefits such as dental coverage.

Rep. Ann Kuster (D-N.H.) said simplifying prior authorization would reduce stress on clinicians already dealing with burnout.

“They’re just so tired of all this paperwork and red tape,” Rep. Kuster said. “In 2022 can’t we at least consider electronic prior authorization?”

At the hearing, Rep. Michael C. Burgess, MD, (R-Tex.) noted that his home state already has taken a step toward reducing the burden of prior authorization with its “gold card” program.

In 2021, a new Texas law called on the state department of insurance to develop rules to require health plans to provide an exemption from preauthorization requirements for a particular health care service if the issuer has approved, or would have approved, at least 90% of the preauthorization requests submitted by the physician or provider for that service. The law also mandates that a physician participating in a peer-to-peer review on behalf of a health benefit plan issuer must be a Texas-licensed physician who has the same or similar specialty as the physician or clinician requesting the service, according to the state insurance department.

Separately, Rep. Suzan DelBene (D-Wash.), the sponsor of the Improving Seniors’ Timely Access to Care Act, told the American Medical Association in a recent interview that she expects the House Ways and Means Committee, on which she serves, to mark up her bill in July. (A mark-up is the process by which a House or Senate committee considers and often amends a bill and then sends it to the chamber’s leadership for a floor vote.)

In a statement issued about the hearing, America’s Health Insurance Plans (AHIP) noted that there has been work in recent years toward streamlining prior authorization. AHIP said it launched the Fast Prior Authorization Technology Highway (Fast PATH) initiative in 2020 to study electronic procedures for handling these reviews.

“The findings of this study showed that ePA delivered improvements with a strong majority of experienced providers reporting faster time to patient care, fewer phone calls and faxes, better understanding of [prior authorization] requirements, and faster time to decisions,” AHIP said.

Physician stress – indeed, the stress level for all medical personnel – has reached new heights.

As if it weren’t enough that doctors work in a profession where it’s almost more a question of when they’ll be sued than if they’ll be sued – where COVID, staff shortages, long hours, and patients frustrated over canceled procedures have caused unrelenting fatigue and stress – they now have to worry that an unhappy patient is going to buy a gun, walk into their office, and kill them.

That’s exactly what happened in Tulsa, Okla., where a patient complaining of pain after back surgery murdered his doctor and several others who happened to be in the wrong place at the wrong time. 

The temptation in the aftermath of such tragedies is to think about preventive measures: Make medical facilities “hardened” targets, like schools have become, with armed guards, metal detectors, automatically locking doors, physical barriers within, security cameras, and buzzers for entry – although hardening a large medical center where members of the community routinely come and go would be challenging.

What about the enormous stress on doctors, nurses, and others in the medical workplace? Physicians who have been sued for malpractice often describe how it changes the way they interact with patients: They now size patients up and make judgments about their potential litigiousness. Will the physicians now look over their patients’ shoulders at the video feed from a security camera when they’re taking a history? Will medical professionals be forced to make snap judgments about patients’ psychological state before deciding whether to treat them?

Remember, there was a time when school shootings were unimaginable. Once one person crosses that line, others inevitably follow.

It could be a drug-seeking patient complaining of ongoing pain, angry because he can’t get a new prescription. It could be a patient whose unpaid bill was turned over to a collection agency, angry because he’s now getting calls from collectors. It could be someone who blames a physician for the loss of a loved one. It could be someone who would otherwise have filed a lawsuit, who now thinks he has a more effective option for exacting retribution.

Most of us would find it unbearable to live and work under the kind of stress faced by medical professionals today. And unfortunately, there is no short-term, systemic relief on the horizon. But there are methods of relieving at least some of the psychological burden being carried by these dedicated individuals.

For starters, the government should provide funds to improve safety and security at medical facilities. It’s sad but it’s a fact of life. The physical structure of schools, along with emergency procedures, have been changed since Columbine and Sandy Hook, and our children and their teachers undergo active shooter drills. Health care facilities will need to adopt similar strategies.

But if we don’t also support the individuals who work in health care, we’ll no longer have even partially staffed health care facilities. Hospitals and medical groups need to be conscious of the effects stress may have on them. Medical staff and administrators need to recognize changes in their colleagues’ behavior and refer those cohorts to professional stress coaches who can get them back on track.

Medical personnel should be picking up on warning signs, like irritability, depression, sudden weight gain or loss, lack of motivation and job satisfaction, obsessiveness, unusual levels of fatigue, alcohol or drug use, and, of course, avoidable medical errors.

In addition, colleagues in the medical workplace need to know each other well. They are usually the first ones to notice if something is off and may be in the best position to refer coworkers for help. Also, medical malpractice insurance carriers should consider encouraging and covering coaching sessions, because helping physicians cope with this heightened stress will prevent medical errors and the lawsuits that inevitably accompany mistakes.

This needn’t be a long-term process like ongoing psychotherapy; a few sessions with a well-trained coach may help psychologically challenged peers restore their focus and perspective. It won’t eliminate the threat any more than litigation stress coaching eliminates the threat of being sued, but it can prevent that stress from leading to avoidable errors. It also can prevent physicians’ personal lives and relationships from going off the rails and driving them out of the medical profession.

None of us can afford to ignore the impacts that these new stressors are having and simply act as if it’s business as usual. The people in the trenches need our help.

It could be a drug-seeking patient complaining of ongoing pain, angry because he can’t get a new prescription. It could be a patient whose unpaid bill was turned over to a collection agency, angry because he’s now getting calls from collectors. It could be someone who blames a physician for the loss of a loved one. It could be someone who would otherwise have filed a lawsuit, who now thinks he has a more effective option for exacting retribution.

Most of us would find it unbearable to live and work under the kind of stress faced by medical professionals today. And unfortunately, there is no short-term, systemic relief on the horizon. But there are methods of relieving at least some of the psychological burden being carried by these dedicated individuals.

For starters, the government should provide funds to improve safety and security at medical facilities. It’s sad but it’s a fact of life. The physical structure of schools, along with emergency procedures, have been changed since Columbine and Sandy Hook, and our children and their teachers undergo active shooter drills. Health care facilities will need to adopt similar strategies.

But if we don’t also support the individuals who work in health care, we’ll no longer have even partially staffed health care facilities. Hospitals and medical groups need to be conscious of the effects stress may have on them. Medical staff and administrators need to recognize changes in their colleagues’ behavior and refer those cohorts to professional stress coaches who can get them back on track.

Medical personnel should be picking up on warning signs, like irritability, depression, sudden weight gain or loss, lack of motivation and job satisfaction, obsessiveness, unusual levels of fatigue, alcohol or drug use, and, of course, avoidable medical errors.

In addition, colleagues in the medical workplace need to know each other well. They are usually the first ones to notice if something is off and may be in the best position to refer coworkers for help. Also, medical malpractice insurance carriers should consider encouraging and covering coaching sessions, because helping physicians cope with this heightened stress will prevent medical errors and the lawsuits that inevitably accompany mistakes.

This needn’t be a long-term process like ongoing psychotherapy; a few sessions with a well-trained coach may help psychologically challenged peers restore their focus and perspective. It won’t eliminate the threat any more than litigation stress coaching eliminates the threat of being sued, but it can prevent that stress from leading to avoidable errors. It also can prevent physicians’ personal lives and relationships from going off the rails and driving them out of the medical profession.

None of us can afford to ignore the impacts that these new stressors are having and simply act as if it’s business as usual. The people in the trenches need our help.

Physician stress – indeed, the stress level for all medical personnel – has reached new heights.

As if it weren’t enough that doctors work in a profession where it’s almost more a question of when they’ll be sued than if they’ll be sued – where COVID, staff shortages, long hours, and patients frustrated over canceled procedures have caused unrelenting fatigue and stress – they now have to worry that an unhappy patient is going to buy a gun, walk into their office, and kill them.

That’s exactly what happened in Tulsa, Okla., where a patient complaining of pain after back surgery murdered his doctor and several others who happened to be in the wrong place at the wrong time. 

The temptation in the aftermath of such tragedies is to think about preventive measures: Make medical facilities “hardened” targets, like schools have become, with armed guards, metal detectors, automatically locking doors, physical barriers within, security cameras, and buzzers for entry – although hardening a large medical center where members of the community routinely come and go would be challenging.

What about the enormous stress on doctors, nurses, and others in the medical workplace? Physicians who have been sued for malpractice often describe how it changes the way they interact with patients: They now size patients up and make judgments about their potential litigiousness. Will the physicians now look over their patients’ shoulders at the video feed from a security camera when they’re taking a history? Will medical professionals be forced to make snap judgments about patients’ psychological state before deciding whether to treat them?

Remember, there was a time when school shootings were unimaginable. Once one person crosses that line, others inevitably follow.

It could be a drug-seeking patient complaining of ongoing pain, angry because he can’t get a new prescription.

Alabama urged a federal court on June 28 to drop its block on the state’s ban on gender-affirming care for transgender youth, citing the Supreme Court’s recent decision to overturn Roe v. Wade.

Alabama Attorney General Steve Marshall said the high court ruled that abortion isn’t protected under the 14th Amendment because it’s not “deeply rooted” in the nation’s history, which he noted could be said about access to gender-affirming care as well, according to Axios.

“No one – adult or child – has a right to transitioning treatments that is deeply rooted in our Nation’s history and tradition,” he wrote in a court document.

“The State can thus regulate or prohibit those interventions for children, even if an adult wants the drugs for his child,” he wrote.

In May, a federal judge blocked part of Alabama’s Senate Bill 184, which makes it a felony for someone to “engage in or cause” certain types of medical care for transgender youths. The law, which was put in place in April, allows for criminal prosecution against doctors, parents, guardians, and anyone else who provides care to a minor. The penalties could result in up to 10 years in prison and up to $15,000 in fines.

At that time, U.S. District Judge Liles Burke issued an injunction to stop Alabama from enforcing the law and allow challenges, including one filed by the Department of Justice. Mr. Burke said the state provided “no credible evidence to show that transitioning medications are ‘experimental.’ ”

“While Defendants offer some evidence that transitioning medications pose certain risks, the uncontradicted record evidence is that at least twenty-two major medical associations in the United States endorse transitioning medications as well-established, evidence-based treatments for gender dysphoria in minors,” he wrote in the ruling.

Medical organizations such as the American Academy of Pediatrics, American Psychological Association, and American Medical Association have urged governors to oppose legislation this year that would restrict gender-affirming medical care, saying that such laws could have negative effects on the mental health of transgender youths.

But on June 28, Mr. Marshall focused on the Constitution and what he believes the recent overturn of Roe implies.

“Just as the parental relationship does not unlock a Due Process right allowing parents to obtain medical marijuana or abortions for their children, neither does it unlock a right to transitioning treatments,” he wrote.

“The Constitution reserves to the State – not courts or medical interest groups – the authority to determine that these sterilizing interventions are too dangerous for minors,” he said.

Since the Supreme Court overturned Roe, people have expressed concerns that lawsuits could now target several rights that are protected under the 14th Amendment, including same-sex relationships, marriage equality, and access to contraceptives.

Justice Clarence Thomas, who wrote a concurring opinion to the majority decision, said the Supreme Court, “in future cases” should reconsider “substantive due process precedents” under previous landmark cases such as Griswold v. Connecticut, Lawrence v. Texas, and Obergefell v. Hodges.

At the same time, Justice Brett Kavanaugh, who also wrote a concurring opinion, said the decision to overturn Roe was only focused on abortion, saying it “does not mean the overruling of those precedents, and does not threaten or cast doubt on those precedents.”

Ain’t gastroenteritis grand?

The Grand Canyon is perhaps America’s greatest natural wonder. The mile-deep gorge of epic proportions, carved over eons by the Colorado River, elicits superlatives of the highest order from those seeing it for the first time. In the past few months, though, visitors to the Grand Canyon have been experiencing a rather more unpleasant sort of reaction: Involuntary bowel evacuation.

Since April, more than 150 river rafters and backcountry campers have fallen ill with bouts of acute gastroenteritis, likely caused by norovirus. Hey, a viral outbreak and our old friend SARS-CoV-2 isn’t involved! Hopefully it won’t get jealous. Whatever the culprit is, however, it got everywhere, as clusters of illness have popped up in unconnected parts of the park and some hikers have been restricted to a smaller portion of the park to avoid further disease spread. The majority of cases occurred in May, so it’s hoped that the outbreak is dying down, but the park remains on alert.

Jon Sullivan/Pixnio

Now, acute gastroenteritis is certainly an unpleasant disease, but it isn’t typically a life-threatening one. There are, however, a couple of unique factors complicating this outbreak. For one, the Grand Canyon is in Arizona (duh), which can get rather hot in the summer months. Expelling waste from both ends becomes rather more dangerous when the thermometer reads over a hundred degrees, and there have been reports of multiple helicopter rescues.

That’s pretty bad, but in a way, they’re the lucky ones. How can we explain this … see, when you visit the Grand Canyon, you’re expected to follow the general rules of Leave No Trace. That means several things, but essentially, if you bring it in, you have to bring it out. Yes, that includes the various consequences of an acute gastroenteritis attack.

Forget spooky campfire stories and hungry wildlife lurking in the night, because true horror is scraping your friend’s diarrhea off the walls of the Grand Canyon into a plastic bag and stuffing it into your backpack. Probably not the sublime one-on-one Grand Canyon experience that people are expecting.
 

Give us a pee! ... for stem cell retrieval

Getting cells for regenerative stem cell treatment has traditionally been painful and difficult – usually they are retrieved by surgical means from bone marrow or fat tissue – but there may be an easier way.

Just pee in a cup.

toeytoey2530/Thinkstock

Apparently, human urine contains stem cells with the potential to be used for regenerative effects. The magic ingredient? The enzyme telomerase, which “is essential for the self-renewal and potential of different types of stem cells” and is related to longevity, according to researchers at Wake Forest Institute for Regenerative Medicine.

They looked into how regenerative telomerase activity is for various capabilities beyond chromosomal stability, and whether these stem cells can become other kinds of cells for optimal tissue repair. Turns out they could, acting as a “distinct subpopulation” that has the ability not only to grow cells but also to morph into other cells, they said in a written statement.

Safety is also an issue. “Being able to use a patient’s own stem cells for therapy is considered advantageous because they do not induce immune responses or rejection,” said Anthony Atala, MD, a coauthor of the study published in Frontiers in Cell and Developmental Biology.

So less risk, easier retrieval, and great regenerative results. If this takes off, the other methods of retrieval could get flushed down the toilet.
 

Politicians playing the long game, literally

Before we get started with actual information, here’s a joke about politicians:

What do you call a lawyer with an IQ of 100? Your Honor.

What do you call a lawyer with an IQ of 50? Senator.

Politics is a dirty business, no doubt, so why do people do it? Is it for the prestige? Seems like everyone hates politicians, so it’s probably not that. Is it their selfless concern for the well-being of others? Probably not that either. Is it for the money? Most members of Congress have more corporate sponsors than a NASCAR driver, but we’re going to pass on that one as well.

Phi Nguyen/House of Representatives

Once again, science gives us the real answer: Longevity. Politicians live longer than the rest of us, and that longevity gap is getting wider.

Investigators looked at data from 11 industrialized countries, some of it going back to 1817, and found that politicians in the United States can expect to live about 7 years longer than the national average. The difference is around 3 years in Switzerland, 4.5 years in Germany, and 6 years in France.

“For almost all countries, politicians had similar rates of mortality to the general population in the late 19th and early 20th centuries. Throughout the 20th century, differences in mortality rates widened significantly across all countries, so that politicians had an increasing survival advantage over the general population,” they said in a written statement.

Income inequality could be a factor, but the longevity gains made by politicians, which started before the 1940s, predate the rise of their earnings relative to the rest of the population, which didn’t really get going until the 1980s, the investigators noted.

Whatever the reason, we have this closing thought regarding our long-lived lawmakers: What’s the difference between a politician and a snail? One is a slimy pest that leaves a trail everywhere. The other is a snail.
 

Land of the free, home of obesity

In the United States, it seems, people are becoming more comfortable with obesity. TikTok and Instagram trends often try to show the world that all sizes are beautiful. There’s also the growing popularity of the dad bod.

America, it has been said, is the land of the free. We love our freedom, and we value our individualism. If an obese man orders three meals from McDonald’s just for himself, no one is going to stop him. Many Americans also have more access to the food they want at any given time, even while they are moving around a lot less because of their sedentary lifestyles.

According to a recent study cited by the New York Post, however, America is not the only country battling obesity. Egypt and Mexico, for example, also have men with higher BMIs who cherish their individualism and the right to eat what they want, Plamen Akaliyski, PhD, of University Carlos III of Madrid, and associates, said in Social Science & Medicine.

Women are not as likely to think the same way. “Men in particular think, ‘I’m an individual, don’t tell me what to do. I’m going to eat what I want,’ ” bariatric surgeon George A. Fielding, MD, said in the Post article. Dr. Fielding also noted that women are three times more likely than men to seek bariatric surgery.

Dr. Akaliyski and associates found that Asian countries such as Japan, Singapore, and South Korea – countries that value thrift, discipline, self control, and delaying gratification – have lower rates of obesity.

So yes, we can go to the drive through of a fast food restaurant whenever we want and order whatever we want, but can doesn’t always mean should.

Investigators looked at data from 11 industrialized countries, some of it going back to 1817, and found that politicians in the United States can expect to live about 7 years longer than the national average. The difference is around 3 years in Switzerland, 4.5 years in Germany, and 6 years in France.

“For almost all countries, politicians had similar rates of mortality to the general population in the late 19th and early 20th centuries. Throughout the 20th century, differences in mortality rates widened significantly across all countries, so that politicians had an increasing survival advantage over the general population,” they said in a written statement.

Income inequality could be a factor, but the longevity gains made by politicians, which started before the 1940s, predate the rise of their earnings relative to the rest of the population, which didn’t really get going until the 1980s, the investigators noted.

Whatever the reason, we have this closing thought regarding our long-lived lawmakers: What’s the difference between a politician and a snail? One is a slimy pest that leaves a trail everywhere. The other is a snail.
 

Land of the free, home of obesity

In the United States, it seems, people are becoming more comfortable with obesity. TikTok and Instagram trends often try to show the world that all sizes are beautiful. There’s also the growing popularity of the dad bod.

America, it has been said, is the land of the free. We love our freedom, and we value our individualism. If an obese man orders three meals from McDonald’s just for himself, no one is going to stop him. Many Americans also have more access to the food they want at any given time, even while they are moving around a lot less because of their sedentary lifestyles.

According to a recent study cited by the New York Post, however, America is not the only country battling obesity. Egypt and Mexico, for example, also have men with higher BMIs who cherish their individualism and the right to eat what they want, Plamen Akaliyski, PhD, of University Carlos III of Madrid, and associates, said in Social Science & Medicine.

Women are not as likely to think the same way. “Men in particular think, ‘I’m an individual, don’t tell me what to do. I’m going to eat what I want,’ ” bariatric surgeon George A. Fielding, MD, said in the Post article. Dr. Fielding also noted that women are three times more likely than men to seek bariatric surgery.

Dr. Akaliyski and associates found that Asian countries such as Japan, Singapore, and South Korea – countries that value thrift, discipline, self control, and delaying gratification – have lower rates of obesity.

So yes, we can go to the drive through of a fast food restaurant whenever we want and order whatever we want, but can doesn’t always mean should.

The World Health Organization declared COVID-19 a pandemic on March 11, 2020, just 4 months before the start of a new residency cycle. Referred to as “COVID interns,” PGY-1 residents transitioning out of medical school in 2020 faced an unprecedented challenge of doctoring within a confused and ill-prepared health care system, while senior residents scrambled to adjust to their rapidly changing training programs. Each subsequent week brought more sobering news of increasing hospitalizations, intensive care unit admissions, and deaths; hospitals across the country resorted to the redeployment of residents across all specialties to buffer the growing need within their internal medicine and critical care units.¹ And while the news and social media blurred into a collage of ventilator shortages, politicization of science, and “#healthcareheroes,” one study showed53.7% of medical interns (N=108) were struggling with mild to extremely severe depression, while 63.9% reported mild to severe anxiety.²

Many shortcomings of our health care system—ill preparedness, racial disparity, health illiteracy—were highlighted during the COVID-19 pandemic, and providers’ mental health was no exception.³ Classic psychosocial risk factors, such as high demands, lack of control, lack of institutional support, and absence of reward defined the workplace, leading Theorell⁴ to call it “a randomized trial for maximal worsening of the work environment.” Stress and burnout during residency are not novel concepts. A 2002 survey including 415 medical residency programs with a response from more than 4000 residents found depressive symptoms in 35% of respondents, paired with feelings of increased cynicism and decreased humanism despite major curricular reforms and duty hour limitations.⁵ Unfortunately, the statistics in the coming years hardly budged and, in the wake of the pandemic, culminated to more than 50% to 76% of physicians worldwide reporting burnout in 2020.^6-8

As a COVID intern at Brigham and Women’s Hospital (Boston, Massachusetts), I also experienced the demanding workload and witnessed the struggle of my colleagues firsthand. Brigham and Women’s Hospital, similar to many of its peer institutions, implemented frequent mental health check-ins within its curriculum. Known as the Intern Humanistic Curriculum, these check-ins essentially were an echo chamber to unload the psychological burdens of our workdays, and we eagerly shared what made us angry, sad, hopeful, and hopeless. During one such session, I learned about moral injury, a term originating in the military defined as the psychological stress resulting from actions—or the lack of actions—that violates one’s moral or ethical code.⁹ With the onslaught of patient deaths for which most of us felt unprepared, we had all endured varying degrees of moral injury. Greenberg et al⁹ described 2 potential outcomes after moral injury: (1) the development of mental health disorders such as depression and posttraumatic stress disorder, or (2) posttraumatic growth, which is the bolstering of psychological resilience. Notably, the outcome is based on the way someone is supported before, during, and after the challenging incident.⁹

With the aim of psychological growth and developing resilience, residents should prioritize mental health throughout their training. To this end, several resources are readily available, many of which I actively use or frequently revisit, which are reviewed here.

Mindfulness Meditation App

Calm (https://www.calm.com/) is one of several popular mobile applications (apps) that delivers mindfulness mediation—the practice of attending to experiences, thoughts, and emotions without bias or judgment. With more than 100 million downloads, Calm includes meditation tutorials, breathing exercises, nature scenes and sounds, and audio programs taught by mindfulness experts for $69.99 a year or $14.99 a month. Systemic reviews have demonstrated reduced sleep disturbance, decreased ruminative thoughts and emotional reactivity, and increased awareness and acceptance in those practicing mindfulness meditation. Calm users have reported these benefits, with many able to forego the time- and cost-intensive cognitive behavioral therapy that requires highly trained therapists.^10-12

Exercise to Relieve Stress

Both aerobic and anaerobic exercises are antidepressive and anxiolytic and also lower one’s overall sensitivity to stress. Whether it is governed by neurotransmitters such as the activation of the opioid systems or the release of endogenous endorphins or time spent focusing on a different task at hand, the benefits of exercise against mental stressors have been extensively studied and established.¹³ Consider obtaining a new gym membership at the start of residency or joining an intramural team. Both have the added benefit of expanding your social circle.

Socialize With Others

Social isolation and perceived loneliness are key stressors linked to neuroendocrine disturbances that underlie depression, anxiety, and even schizophrenia.^14,15 Throughout residency there will be several social events and opportunities to gather with colleagues—inside or outside of the work environment—and residents should attend as time allows. Even virtual social interactions were found to reduce stress and help in the treatment of social anxiety disorder.¹⁴

Open up to your co-residents, friends, and family about any struggles that may be invisible on the outside. Even attendings can empathize with the struggles of residency, and the mentors in place are actively trained to prioritize resident wellness. If verbal communication is not your strength, try journaling. Writing helps to untangle and better define underlying stressors and is itself meditative.^16,17 However, ensure that your journaling is focused on positive emotional responses and aims to determine the positive benefits within any stressful event; those solely expressing negative emotions were found to have higher levels of stress and anxiety afterward than they had before.¹⁷

Seek a Mental Health Specialist

As with all other human ailments, severe mental health disorders require specialists and proper medication. Unfortunately, substantial stigma accompanying mental health continues to permeate medicine, creating considerable barriers for residents in need of care.¹⁸ A 2016 survey of more than 2000 physicians found that those with mental illnesses did not seek treatment due to limited time, fear of being reported to a medical licensing board, concern over obtaining licensure, and shame or embarrassment at the diagnosis.¹⁹ Besides urging residents to seek care, more effort should be invested in addressing the stigma and ensuring confidentiality. In 2021, the internal medicine and medicine-pediatrics residency at the University of Colorado Anschutz Medical Campus (Aurora, Colorado) developed a confidential opt-out, rather than opt-in, mental health program, and appointments were made for all 80 interns in advance. In doing so, they found increased participation and self-reported wellness at a relatively low cost and simple implementation.²⁰ For trainees without such access, online or mobile therapy platforms offering electronic mental health treatment or telepsychiatry also have been employed.^21,22 The onus ultimately is still on the individual to seek the care they need. Although only an anecdotal piece of evidence, I have found the prevalence of physicians taking selective serotonin reuptake inhibitors such as escitalopram, sertraline, or fluoxetine to be strikingly common and quite beneficial.

Final Thoughts

Residency remains rife with financial, emotional, and physical stressors; even as the dust settles on the COVID-19 pandemic, the light shed on the importance of trainee mental health must remain illuminated. For the aforementioned resources to have an impact, residents need to be empowered to openly discuss mental health issues and to seek help if necessary. Finally, in 2018, the Journal of Graduate Medical Education published a 10-year prospective cohort study that found that emotional distress during residency persists in professional practice even 10 years after residency and is associated with future burnout.²³ Trainees should consider prioritizing their mental health to not only improve their quality of life in the present but also as an investment for their future.

Basal cell carcinoma (BCC) is the most common keratinocyte carcinoma and affects more than 3 million individuals per year in the United States.¹ Approximately 40% of patients diagnosed with BCC will develop another BCC within 5 years of the initial diagnosis.² Most cases are successfully treated with surgical excision and occasionally topical therapy or radiotherapy. Despite the high cure rate with conventional treatments, BCC can recur and can cause substantial destruction of the surrounding tissue if left untreated.^3-5 In some instances, BCC can even metastasize and lead to death.⁶ For patients who are poor candidates for surgical or topical treatment modalities because of locally advanced BCC (laBCC) or metastatic BCC (mBCC), systemic treatment may be indicated. Vismodegib, sonidegib, and cemiplimab are the only systemic medications approved by the US Food and Drug Administration (FDA) for the treatment of laBCC and/or mBCC. Vismodegib and sonidegib target the sonic hedgehog (SHH) signaling pathway that is abnormally activated in more than 90% of BCCs.⁷ Cemiplimab is an immune checkpoint inhibitor (ICI) that targets the programmed cell death protein 1 (PD-1) receptor.⁸ Herein, we review the clinical utility of these medications and their evolving roles in the treatment of BCC.

SHH Pathway Inhibitors

The SHH pathway is a key regulator of cell proliferation and differentiation during embryogenesis.⁷ During adulthood, SHH signaling decreases but still plays an important role in stem cell activation and in regulation of the hair follicle growth cycle.^9,10 However, de novo mutations in the genes that comprise the SHH pathway can result in aberrant constitutive activation, leading to unrestricted cell proliferation. Genetic mutations resulting in activation of Smoothened (SMO), a G-protein–coupled receptor involved in the signal transduction and propagation of the SHH pathway, have been implicated in the pathogenesis of BCC. Inactivating mutations also are commonly observed in patched homolog 1, an upstream cell-surface protein that inhibits SMO.⁷ The mechanism by which vismodegib and sonidegib, 2 of the FDA-approved oral medications for the treatment of advanced BCC, block the SHH pathway is through the selective inhibition of SMO.^7,11

Vismodegib first received FDA approval in 2012 for the treatment of laBCC and mBCC after initial results from the pivotal ERIVANCE phase 2 trial demonstrated an objective response rate (ORR) of 43% (27/63) and 30% (10/33) in patients with locally advanced and metastatic disease, respectively. In this single-arm study, all enrolled patients (63 with laBCC and 33 with mBCC) received 150 mg of oral vismodegib daily.¹² Updated results at 39 months demonstrated improved ORRs of 60% (38/63) and 48% (16/33) for the laBCC and mBCC groups, respectively. A complete response (CR) and partial response (PR) were observed in 32% (n=20) and 29% (n=18) of patients with laBCC, respectively.¹³ These results have been confirmed in subsequent studies, including the large international open-label trial known as STEVIE, with ORRs of 68.5% for 1119 cases of laBCC and 37% for 96 cases of mBCC.^14-17 The CR and PR rates were 33% and 35%, respectively, for the laBCC group. The CR and PR rates for the mBCC group were 5% and 32%, respectively.¹⁴

The FDA approval of sonidegib for laBCC—but not mBCC—occurred in 2015 after the pivotal BOLT randomized phase 2 trial demonstrated an initial ORR of 43% (18/42) for laBCC and 15% (2/13) for mBCC after administration of 200 mg of sonidegib daily.¹⁸ A final follow-up analysis at 42 months resulted in ORRs of 56% (37/66) and 8% (1/13) for the laBCC and mBCC groups, respectively.¹⁹ Additionally, improved efficacy was not observed in the 151 patients who were randomized to receive treatment with the higher 800-mg dose; however, they did experience a higher incidence of adverse events.^18,19

Currently, the true clinical differences between vismodegib and sonidegib remain uncertain, as no head-to-head trials have been conducted. Moreover, direct comparison of the data from the ERIVANCE and BOLT trials is challenging owing to fundamental differences in methodologic design, including the criteria used to assess BCC severity. The ERIVANCE trial utilized the conventional Response Evaluation Criteria in Solid Tumors (RECIST), while BOLT used the rigorous modified RECIST. However, an expert consensus study attempted to compare the 2 trials by modifying the outcomes from BOLT with the former RECIST criteria. The expert group found that the 2 SHH inhibitors had comparable efficacy and adverse event profiles.²⁰ Nevertheless, a recent meta-analysis found that although ORRs for laBCC were similar between the 2 drugs, the CR rate for vismodegib was 31% compared with 3% for sonidegib. Additionally, for mBCC, they reported the ORR of vismodegib to be 2.7 times higher than that of sonidegib (39% vs 15%).²¹

Immune Checkpoint Inhibitors

Immune checkpoint inhibitors have successfully been utilized in the treatment of cutaneous squamous cell carcinoma (cSCC); however, their use for treating BCC has been limited until recently.^22-25 In February 2021, cemiplimab became the first and only ICI approved for the treatment of laBCC and mBCC in patients who did not respond to or were intolerant to prior SHH inhibitor therapy.²⁶ Cemiplimab—a human monoclonal antibody against the PD-1 receptor expressed on T cells—blocks its interaction with programmed cell death ligand 1 and programmed cell death ligand 2 present on tumor cells. The blockade of the PD-1 pathway releases the inhibition of the antitumor immune response and enables appropriate cytotoxic T-cell activity to occur.⁸

The FDA approval of cemiplimab for the treatment of advanced BCC was based on an open-label, multicenter, single-arm phase 2 trial (NCT03132636) evaluating 84 patients with laBCC refractory or intolerant to SHH inhibitor therapy.²⁶ Patients received an intravenous infusion of cemiplimab 350 mg every 3 weeks for up to 93 weeks or until disease progression or unacceptable toxicity. An ORR of 31% (26/84) was observed with a CR and PR of 6% (5/84) and 25% (21/84), respectively. The median duration of follow-up was 15 months.²⁶ Given the clinically meaningful results of this trial, investigating the efficacy of other PD-1 inhibitors, such as pembrolizumab and nivolumab, for treatment of advanced BCC may prove worthwhile.

The 2 approved SHH inhibitors—vismodegib and sonidegib—appear to have similar side-effect profiles, with the most common adverse effects being muscle spasms, dysgeusia, alopecia, nausea, vomiting, diarrhea, weight loss, and fatigue.^20,21,27 These side effects occur at high frequencies (>40%) for both SHH inhibitors and often lead to discontinuation of the medication.²¹ Rates of treatment discontinuation range from 15% to 50% on average.^12-14,18 Fortunately, the majority of these adverse effects do not appear to increase in severity or frequency with prolonged use of these medications.^14,16,28

Various conservative and pharmacologic measures can be implemented to help manage side effects. For muscle spasms, which are the most commonly reported adverse effect, supplementation with magnesium, transcutaneous electrical nerve stimulation, acupuncture, massages, stretching, and thermal compresses can potentially be beneficial.²⁹ Calcium channel blockers also may be effective, as one small prospective cohort study reported a reduction in the frequency of muscle cramps with amlodipine 10 mg daily.³⁰ For alopecia, which typically is reversible and caused by SHH inhibition of the normal hair cycle, minoxidil theoretically can help, as it reduces telogen arrest and extends the anagen growth phase.^31,32 Although usually mild and self-limiting, management of dysgeusia, weight loss, and gastrointestinal upset often can be managed with dietary changes, such as smaller, more frequent meals.^33,34 Finally, alternative dosing strategies and drug holidays have been employed to mitigate these side effects and increase drug tolerability.^35,36 These are discussed in the Alternative Dosing section.

Given the essential role of the SHH pathway in embryologic development, SHH inhibitors carry a black box warning of embryofetal teratogenicity and are contraindicated in females who are pregnant or breastfeeding. For females of reproductive potential, verification of pregnancy status should be performed prior to initiating treatment with an SHH inhibitor. These patients should be counseled on the use of contraception during treatment and for at least 24 months and 20 months after cessation of vismodegib and sonidegib, respectively.^27,37,38 Male patients, even after a vasectomy, should use barrier contraception during treatment and for at least 3 months and 8 months after the final dose of vismodegib and sonidegib, respectively.^37,38

Laboratory abnormalities commonly associated with SHH inhibitors include elevated hepatic enzymes, particularly with vismodegib, and elevated creatine kinase levels, particularly with sonidegib.^28,39 Other laboratory abnormalities that can occur include hypercholesterolemia, hypercreatininemia, hyperglycemia, and increased serum lipase levels.^19,28 Although these laboratory abnormalities usually are asymptomatic and self-limiting, regular monitoring should be performed.

There also is concern that SHH inhibitors may induce the development of cSCC. A case-control study of 55 cases and 125 control patients found an increased risk for cSCC in those previously treated with vismodegib, with a hazard ratio of 8.12.⁴⁰ However, a subsequent retrospective cohort study of 1675 patients with BCC failed to find any association with cSCC among those treated with vismodegib compared to those who received standard surgical therapy.⁴¹ Clinical data for sonidegib are lacking, but the BOLT trial found that cSCC occurred in 3 patients receiving treatment with the SHH inhibitor.¹⁸ Thus, further studies are needed to more thoroughly assess this concern. Close monitoring for cSCC may be warranted in patients prescribed SHH inhibitors at this time.

Cemiplimab has demonstrated an acceptable safety profile and is generally well tolerated. In the phase 2 trial of cemiplimab for cSCC, approximately 5% of patients discontinued treatment because of adverse effects. The most commonly reported side effects of cemiplimab were diarrhea (27%), fatigue (24%), nausea (17%), constipation (15%), and rash (15%).²³ In the phase 2 trial for laBCC, grade 3 or 4 adverse events occurred in 48% of patients, with hypertension (5%) being the most common.²⁶ Although rare, immune-mediated adverse reactions also can occur, given the mechanism of action of ICIs. These side effects, ranging in severity from mild to fatal, include pneumonitis, colitis, hepatitis, nephritis, myocarditis, and hypophysitis. Therefore, close monitoring for these immune-mediated reactions is critical, but most can be managed with corticosteroids or treatment interruption if they occur.^42,43

No absolute contraindications exist for cemiplimab; however, extreme caution should be taken in immunosuppressed individuals, such as solid organ transplant recipients and those with chronic lymphocytic leukemia (CLL), as safety data are limited in these patients.^44,45 Although small retrospective studies have reported reasonable tolerability in solid organ transplant recipients treated with ICIs, an allograft rejection rate of 41% was found in a meta-analysis of 64 patients.^46-48 In CLL patients with keratinocyte carcinomas, ICIs have been safely used and have even demonstrated efficacy for CLL in some cases.^49-52

Alternative Dosing

The side effects of SHH inhibitors have led to alternative dosing strategies to prevent medication discontinuation and improve adherence. In patients with basal cell nevus syndrome, multimonth drug holidays have been shown to increase drug tolerability without compromising efficacy.^35,36 Weekly intermittent dosing regimens of vismodegib ranging from 1 week on followed by 1 to 3 weeks off demonstrated efficacy in a retrospective study of 7 patients with advanced BCC.⁵³ All 7 patients experienced improvement in their BCCs, with 3 patients experiencing CR. Importantly, treatment-related adverse effects were mild and well tolerated, with no patients terminating the medication.⁵³ Two other retrospective case series of patients with advanced BCC treated with vismodegib reported similar findings for those placed on an intermittent dosing schedule ranging from once every other day to once per week.^54,55

In the large phase 2 randomized trial known as MIKIE, 2 different intermittent dosing regimens of 150 mg vismodegib daily for patients with multiple BCCs were found to have good activity and tolerability.⁵⁶ The first group (n=116) received vismodegib for 12 weeks, then 3 rounds of 8 weeks of placebo, followed by 12 weeks of vismodegib; there was a 63% reduction in clinically evident BCCs after 73 weeks. The second group (n=113) received the medication for 24 weeks, then 3 rounds of 8 weeks of placebo, followed by 8 weeks of vismodegib; there was a 54% reduction at the end of 73 weeks.⁵⁶ Subsequent analyses found improvements in health-related quality-of-life outcomes that were similar for both groups.⁵⁷

Consequently, alternative dosing schedules appear to be a viable option for patients at risk of discontinuing treatment because of adverse effects, and current data support the recently approved recommendations of dose interruptions of up to 8 weeks to manage adverse effects in patients with laBCC or mBCC.⁵⁸ Nevertheless, further clinical studies are required to determine the optimal intermittent dosing regimen for patients treated with SHH inhibitors.

Neoadjuvant Administration

Recently, vismodegib has been studied as a neoadjuvant therapy for BCC with promising results. Several small retrospective studies and case reports have documented successful treatment of both operable and inoperable periocular laBCC, with preservation of the eye in all patients.^59-61 An open-label trial of 15 patients with advanced BCC who received neoadjuvant vismodegib for 3 to 6 months prior to surgical excision reported a mean reduction of 35% in the final surgical defect size, with no recurrence at 22 months.^62,63 The latest and largest study performed was a phase 2 open-label trial known as VISMONEO, where 44 of 55 laBCC patients (80%) receiving neoadjuvant vismodegib for a mean duration of 6 months (range, 4–10 months) achieved the primary end point of tumor surgical downstaging.⁶⁴ Of the 44 patients who had tumor downstaging, 27 (61%) experienced histologically proven CRs. Additionally, a 66% reduction in the average target lesion size was reported in this group compared to29% in the 11 patients who did not have tumor downstaging (P=.0002).⁶⁴ Thus, SHH inhibitors may hold an important neoadjuvant role in the treatment of BCC by decreasing surgical defect size and allowing for surgical management of previously inoperable cases.

Synergism With Radiation

Preliminary data suggest SHH inhibitors may help potentiate the effects of radiation therapy for the treatment of BCC. Currently, the evidence primarily is limited to case studies, with several reports describing complete remission in patients with advanced BCCs who were considered unsuitable candidates for surgery. In these cases, vismodegib was administered either prior to or concurrently with radiation treatment.^65-69 An in vitro study also documented the radiation-sensitizing effects of vismodegib in a BCC cell line.⁷⁰ Recently, a phase 2 trial (ClinicalTrials.gov identifier NCT01835626) evaluating the concurrent use of vismodegib and radiotherapy for patients with advanced BCC was completed, but data has yet to be published.

Synergism With and Benefit of Antifungal Therapy

The antifungal drug itraconazole is a potent inhibitor of the SHH pathway and may have an adjunctive role in the treatment of BCC. Similar to vismodegib and sonidegib, itraconazole acts as a direct antagonist of SMO. However, it is thought to bind to a distinct site on SMO.^71,72 An open-label, exploratory phase 2 trial of 19 patients with BCC found that oral itraconazole 200 to 400 mg daily decreased tumor proliferative index by 45% (P=.04), as measured by Ki-67; SHH activity by 65% (P=.03), as measured by GLI1 messenger RNA; and mean tumor area by 24%.⁷³ In a case series of 5 patients with mBCC refractory to conventional SHH inhibitor therapy, combined treatment with itraconazole and arsenic trioxide resulted in stable disease and a 75% reduction in SHH activity (P<.001).⁷⁴ One case report documented tumor regression leading to stable disease for 15 months in a patient with laBCC treated with itraconazole monotherapy due to being unable to afford vismodegib or sonidegib. However, within 2 months of treatment discontinuation, the lesion progressed considerably.⁷⁵ The efficacy of a topical formulation of itraconazole also has been tested in an open-label, placebo-controlled phase 2 trial, but no benefit was observed.⁷⁶

Posaconazole is a second-generation antifungal agent that may serve as a potential alternative to itraconazole.⁷⁷ Although clinical data are lacking, a basic science study found that posaconazole could inhibit the growth of SHH-dependent BCC in vivo (in mice).⁷⁸ Furthermore, posaconazole has demonstrated a better safety profile with fewer and more mild side effects than itraconazole and does not require dose adjustment for those with hepatic or renal failure.^79,80 Thus, posaconazole may be a safer alternative to itraconazole for the treatment of BCC. Further clinical studies are needed to elucidate the potential synergistic effects of these antifungal agents with the 2 currently approved SHH inhibitors for the treatment of advanced BCC.

Treatment resistance to SHH inhibitors, though uncommon, is a growing concern. Acquired mutations in the SMO binding site or downstream mediators of the SHH pathway have been shown to confer resistance to vismodegib and sonidegib.^72,81-83 In addition, it appears that there may be shared resistance among the drugs in this class. One study assessing the efficacy of sonidegib in 9 patients with laBCC resistant to vismodegib found that these patients also did not respond to sonidegib.⁸⁴ Interestingly, 1 case report documented tumor regression of an intracranial BCC in a patient treated with sonidegib and itraconazole after failure with vismodegib.⁸⁵ An in vitro study also found that itraconazole maintained SHH inhibitory activity for all drug-resistant SMO mutations that have been reported.⁷² Therefore, itraconazole monotherapy or combination therapy with a canonical SHH inhibitor may be considered for patients with recalcitrant BCC and warrants further investigation.

Taladegib is a newly developed SMO inhibitor that may serve as another promising alternative for patients who develop resistance to vismodegib or sonidegib. A phase 1 trial of taladegib for advanced BCC found an ORR of 69% (11/16) in the SHH inhibitor–naïve group and an ORR of 36% (11/32) in the group previously treated with a SHH inhibitor.⁸⁶ Additionally, the safety profile and frequency of adverse effects appear to be similar to those associated with vismodegib and sonidegib.^86,87 Unfortunately, no clinical trials evaluating taladegib for BCC are ongoing or in development at this time.

Recurrence

There appears to be a relatively high rate of recurrence for BCC patients who achieve a CR to SHH inhibitors. In a retrospective study of 116 laBCC patients who experienced a CR after vismodegib therapy, 54 patients (47%) relapsed at 36 months. Among the 54 patients that relapsed, 27 were re-treated with vismodegib, which resulted in an ORR of 85% (23/27), a CR rate of 37% (10/27), and a PR rate of 48% (13/27).⁸⁸ Another retrospective study of 35 laBCC patients who relapsed after vismodegib treatment reported a 31% (11/35) clinical recurrence rate at 6-month follow-up.⁸⁹ An observational retrospective study also assessed the efficacy of SHH inhibitor maintenance therapy for advanced BCC patients who achieved a CR.⁹⁰ In the study, 27 (64%) patients received a maintenance dose of 150 mg vismodegib once per week for 1 year, while 15 (36%) patients decided not to take a maintenance dose following CR of their BCC. All patients who took the maintenance therapy did not experience clinical recurrence at 1-year follow-up, whereas 26% of patients not on the maintenance dose relapsed.⁹⁰ Consequently, these results indicate that BCC recurrence is frequent after SHH inhibitor therapy and highlights the importance of close surveillance after CR is attained. Nevertheless, most patients still respond to treatment with SHH inhibitors after relapsing, and intermittent maintenance doses may be an effective means to reduce risk of recurrence.

Conclusion

Vismodegib and sonidegib are SHH inhibitors approved for the treatment of laBCC and mBCC. Cemiplimab is now also approved for patients who do not respond to SHH inhibitors or for whom SHH inhibitors are not tolerable. Although these systemic targeted therapies can lead to notable tumor shrinkage and even complete regression in some patients, recurrence is common, and adverse effects may limit their use. Drug resistance is an emerging issue that requires additional examination. Further clinical studies are needed to determine which patients are likely to respond to these targeted treatments.

Various intermittent and maintenance drug regimens should be evaluated for their potential to mitigate adverse effects and reduce risk of recurrence, respectively. The synergistic effects of these medications with other therapies as well as their neoadjuvant and adjuvant roles should be further investigated. For example, administration of an SHH inhibitor prior to surgical excision of a BCC may allow for a smaller surgical defect size, thereby improving cosmetic and functional outcomes. Moreover, these systemic targeted medications may allow for previously inoperable tumors to become amenable to surgical treatment.

Although SHH inhibitors and PD-1 inhibitors represent a major advancement in the field of oncodermatology, real-world efficacy and safety data in the upcoming years will be important for elucidating their true benefit for patients with BCC.

Basal cell carcinoma (BCC) is the most common keratinocyte carcinoma and affects more than 3 million individuals per year in the United States.¹ Approximately 40% of patients diagnosed with BCC will develop another BCC within 5 years of the initial diagnosis.² Most cases are successfully treated with surgical excision and occasionally topical therapy or radiotherapy. Despite the high cure rate with conventional treatments, BCC can recur and can cause substantial destruction of the surrounding tissue if left untreated.^3-5 In some instances, BCC can even metastasize and lead to death.⁶ For patients who are poor candidates for surgical or topical treatment modalities because of locally advanced BCC (laBCC) or metastatic BCC (mBCC), systemic treatment may be indicated. Vismodegib, sonidegib, and cemiplimab are the only systemic medications approved by the US Food and Drug Administration (FDA) for the treatment of laBCC and/or mBCC. Vismodegib and sonidegib target the sonic hedgehog (SHH) signaling pathway that is abnormally activated in more than 90% of BCCs.⁷ Cemiplimab is an immune checkpoint inhibitor (ICI) that targets the programmed cell death protein 1 (PD-1) receptor.⁸ Herein, we review the clinical utility of these medications and their evolving roles in the treatment of BCC.

SHH Pathway Inhibitors

The SHH pathway is a key regulator of cell proliferation and differentiation during embryogenesis.⁷ During adulthood, SHH signaling decreases but still plays an important role in stem cell activation and in regulation of the hair follicle growth cycle.^9,10 However, de novo mutations in the genes that comprise the SHH pathway can result in aberrant constitutive activation, leading to unrestricted cell proliferation. Genetic mutations resulting in activation of Smoothened (SMO), a G-protein–coupled receptor involved in the signal transduction and propagation of the SHH pathway, have been implicated in the pathogenesis of BCC. Inactivating mutations also are commonly observed in patched homolog 1, an upstream cell-surface protein that inhibits SMO.⁷ The mechanism by which vismodegib and sonidegib, 2 of the FDA-approved oral medications for the treatment of advanced BCC, block the SHH pathway is through the selective inhibition of SMO.^7,11

Vismodegib first received FDA approval in 2012 for the treatment of laBCC and mBCC after initial results from the pivotal ERIVANCE phase 2 trial demonstrated an objective response rate (ORR) of 43% (27/63) and 30% (10/33) in patients with locally advanced and metastatic disease, respectively. In this single-arm study, all enrolled patients (63 with laBCC and 33 with mBCC) received 150 mg of oral vismodegib daily.¹² Updated results at 39 months demonstrated improved ORRs of 60% (38/63) and 48% (16/33) for the laBCC and mBCC groups, respectively. A complete response (CR) and partial response (PR) were observed in 32% (n=20) and 29% (n=18) of patients with laBCC, respectively.¹³ These results have been confirmed in subsequent studies, including the large international open-label trial known as STEVIE, with ORRs of 68.5% for 1119 cases of laBCC and 37% for 96 cases of mBCC.^14-17 The CR and PR rates were 33% and 35%, respectively, for the laBCC group. The CR and PR rates for the mBCC group were 5% and 32%, respectively.¹⁴

The FDA approval of sonidegib for laBCC—but not mBCC—occurred in 2015 after the pivotal BOLT randomized phase 2 trial demonstrated an initial ORR of 43% (18/42) for laBCC and 15% (2/13) for mBCC after administration of 200 mg of sonidegib daily.¹⁸ A final follow-up analysis at 42 months resulted in ORRs of 56% (37/66) and 8% (1/13) for the laBCC and mBCC groups, respectively.¹⁹ Additionally, improved efficacy was not observed in the 151 patients who were randomized to receive treatment with the higher 800-mg dose; however, they did experience a higher incidence of adverse events.^18,19

Currently, the true clinical differences between vismodegib and sonidegib remain uncertain, as no head-to-head trials have been conducted. Moreover, direct comparison of the data from the ERIVANCE and BOLT trials is challenging owing to fundamental differences in methodologic design, including the criteria used to assess BCC severity. The ERIVANCE trial utilized the conventional Response Evaluation Criteria in Solid Tumors (RECIST), while BOLT used the rigorous modified RECIST. However, an expert consensus study attempted to compare the 2 trials by modifying the outcomes from BOLT with the former RECIST criteria. The expert group found that the 2 SHH inhibitors had comparable efficacy and adverse event profiles.²⁰ Nevertheless, a recent meta-analysis found that although ORRs for laBCC were similar between the 2 drugs, the CR rate for vismodegib was 31% compared with 3% for sonidegib. Additionally, for mBCC, they reported the ORR of vismodegib to be 2.7 times higher than that of sonidegib (39% vs 15%).²¹

Immune Checkpoint Inhibitors

Immune checkpoint inhibitors have successfully been utilized in the treatment of cutaneous squamous cell carcinoma (cSCC); however, their use for treating BCC has been limited until recently.^22-25 In February 2021, cemiplimab became the first and only ICI approved for the treatment of laBCC and mBCC in patients who did not respond to or were intolerant to prior SHH inhibitor therapy.²⁶ Cemiplimab—a human monoclonal antibody against the PD-1 receptor expressed on T cells—blocks its interaction with programmed cell death ligand 1 and programmed cell death ligand 2 present on tumor cells. The blockade of the PD-1 pathway releases the inhibition of the antitumor immune response and enables appropriate cytotoxic T-cell activity to occur.⁸

The FDA approval of cemiplimab for the treatment of advanced BCC was based on an open-label, multicenter, single-arm phase 2 trial (NCT03132636) evaluating 84 patients with laBCC refractory or intolerant to SHH inhibitor therapy.²⁶ Patients received an intravenous infusion of cemiplimab 350 mg every 3 weeks for up to 93 weeks or until disease progression or unacceptable toxicity. An ORR of 31% (26/84) was observed with a CR and PR of 6% (5/84) and 25% (21/84), respectively. The median duration of follow-up was 15 months.²⁶ Given the clinically meaningful results of this trial, investigating the efficacy of other PD-1 inhibitors, such as pembrolizumab and nivolumab, for treatment of advanced BCC may prove worthwhile.

The 2 approved SHH inhibitors—vismodegib and sonidegib—appear to have similar side-effect profiles, with the most common adverse effects being muscle spasms, dysgeusia, alopecia, nausea, vomiting, diarrhea, weight loss, and fatigue.^20,21,27 These side effects occur at high frequencies (>40%) for both SHH inhibitors and often lead to discontinuation of the medication.²¹ Rates of treatment discontinuation range from 15% to 50% on average.^12-14,18 Fortunately, the majority of these adverse effects do not appear to increase in severity or frequency with prolonged use of these medications.^14,16,28

Various conservative and pharmacologic measures can be implemented to help manage side effects. For muscle spasms, which are the most commonly reported adverse effect, supplementation with magnesium, transcutaneous electrical nerve stimulation, acupuncture, massages, stretching, and thermal compresses can potentially be beneficial.²⁹ Calcium channel blockers also may be effective, as one small prospective cohort study reported a reduction in the frequency of muscle cramps with amlodipine 10 mg daily.³⁰ For alopecia, which typically is reversible and caused by SHH inhibition of the normal hair cycle, minoxidil theoretically can help, as it reduces telogen arrest and extends the anagen growth phase.^31,32 Although usually mild and self-limiting, management of dysgeusia, weight loss, and gastrointestinal upset often can be managed with dietary changes, such as smaller, more frequent meals.^33,34 Finally, alternative dosing strategies and drug holidays have been employed to mitigate these side effects and increase drug tolerability.^35,36 These are discussed in the Alternative Dosing section.

Given the essential role of the SHH pathway in embryologic development, SHH inhibitors carry a black box warning of embryofetal teratogenicity and are contraindicated in females who are pregnant or breastfeeding. For females of reproductive potential, verification of pregnancy status should be performed prior to initiating treatment with an SHH inhibitor. These patients should be counseled on the use of contraception during treatment and for at least 24 months and 20 months after cessation of vismodegib and sonidegib, respectively.^27,37,38 Male patients, even after a vasectomy, should use barrier contraception during treatment and for at least 3 months and 8 months after the final dose of vismodegib and sonidegib, respectively.^37,38

Laboratory abnormalities commonly associated with SHH inhibitors include elevated hepatic enzymes, particularly with vismodegib, and elevated creatine kinase levels, particularly with sonidegib.^28,39 Other laboratory abnormalities that can occur include hypercholesterolemia, hypercreatininemia, hyperglycemia, and increased serum lipase levels.^19,28 Although these laboratory abnormalities usually are asymptomatic and self-limiting, regular monitoring should be performed.

There also is concern that SHH inhibitors may induce the development of cSCC. A case-control study of 55 cases and 125 control patients found an increased risk for cSCC in those previously treated with vismodegib, with a hazard ratio of 8.12.⁴⁰ However, a subsequent retrospective cohort study of 1675 patients with BCC failed to find any association with cSCC among those treated with vismodegib compared to those who received standard surgical therapy.⁴¹ Clinical data for sonidegib are lacking, but the BOLT trial found that cSCC occurred in 3 patients receiving treatment with the SHH inhibitor.¹⁸ Thus, further studies are needed to more thoroughly assess this concern. Close monitoring for cSCC may be warranted in patients prescribed SHH inhibitors at this time.

Cemiplimab has demonstrated an acceptable safety profile and is generally well tolerated. In the phase 2 trial of cemiplimab for cSCC, approximately 5% of patients discontinued treatment because of adverse effects. The most commonly reported side effects of cemiplimab were diarrhea (27%), fatigue (24%), nausea (17%), constipation (15%), and rash (15%).²³ In the phase 2 trial for laBCC, grade 3 or 4 adverse events occurred in 48% of patients, with hypertension (5%) being the most common.²⁶ Although rare, immune-mediated adverse reactions also can occur, given the mechanism of action of ICIs. These side effects, ranging in severity from mild to fatal, include pneumonitis, colitis, hepatitis, nephritis, myocarditis, and hypophysitis. Therefore, close monitoring for these immune-mediated reactions is critical, but most can be managed with corticosteroids or treatment interruption if they occur.^42,43

No absolute contraindications exist for cemiplimab; however, extreme caution should be taken in immunosuppressed individuals, such as solid organ transplant recipients and those with chronic lymphocytic leukemia (CLL), as safety data are limited in these patients.^44,45 Although small retrospective studies have reported reasonable tolerability in solid organ transplant recipients treated with ICIs, an allograft rejection rate of 41% was found in a meta-analysis of 64 patients.^46-48 In CLL patients with keratinocyte carcinomas, ICIs have been safely used and have even demonstrated efficacy for CLL in some cases.^49-52

Alternative Dosing

The side effects of SHH inhibitors have led to alternative dosing strategies to prevent medication discontinuation and improve adherence. In patients with basal cell nevus syndrome, multimonth drug holidays have been shown to increase drug tolerability without compromising efficacy.^35,36 Weekly intermittent dosing regimens of vismodegib ranging from 1 week on followed by 1 to 3 weeks off demonstrated efficacy in a retrospective study of 7 patients with advanced BCC.⁵³ All 7 patients experienced improvement in their BCCs, with 3 patients experiencing CR. Importantly, treatment-related adverse effects were mild and well tolerated, with no patients terminating the medication.⁵³ Two other retrospective case series of patients with advanced BCC treated with vismodegib reported similar findings for those placed on an intermittent dosing schedule ranging from once every other day to once per week.^54,55

In the large phase 2 randomized trial known as MIKIE, 2 different intermittent dosing regimens of 150 mg vismodegib daily for patients with multiple BCCs were found to have good activity and tolerability.⁵⁶ The first group (n=116) received vismodegib for 12 weeks, then 3 rounds of 8 weeks of placebo, followed by 12 weeks of vismodegib; there was a 63% reduction in clinically evident BCCs after 73 weeks. The second group (n=113) received the medication for 24 weeks, then 3 rounds of 8 weeks of placebo, followed by 8 weeks of vismodegib; there was a 54% reduction at the end of 73 weeks.⁵⁶ Subsequent analyses found improvements in health-related quality-of-life outcomes that were similar for both groups.⁵⁷

Consequently, alternative dosing schedules appear to be a viable option for patients at risk of discontinuing treatment because of adverse effects, and current data support the recently approved recommendations of dose interruptions of up to 8 weeks to manage adverse effects in patients with laBCC or mBCC.⁵⁸ Nevertheless, further clinical studies are required to determine the optimal intermittent dosing regimen for patients treated with SHH inhibitors.

Neoadjuvant Administration

Recently, vismodegib has been studied as a neoadjuvant therapy for BCC with promising results. Several small retrospective studies and case reports have documented successful treatment of both operable and inoperable periocular laBCC, with preservation of the eye in all patients.^59-61 An open-label trial of 15 patients with advanced BCC who received neoadjuvant vismodegib for 3 to 6 months prior to surgical excision reported a mean reduction of 35% in the final surgical defect size, with no recurrence at 22 months.^62,63 The latest and largest study performed was a phase 2 open-label trial known as VISMONEO, where 44 of 55 laBCC patients (80%) receiving neoadjuvant vismodegib for a mean duration of 6 months (range, 4–10 months) achieved the primary end point of tumor surgical downstaging.⁶⁴ Of the 44 patients who had tumor downstaging, 27 (61%) experienced histologically proven CRs. Additionally, a 66% reduction in the average target lesion size was reported in this group compared to29% in the 11 patients who did not have tumor downstaging (P=.0002).⁶⁴ Thus, SHH inhibitors may hold an important neoadjuvant role in the treatment of BCC by decreasing surgical defect size and allowing for surgical management of previously inoperable cases.

Synergism With Radiation

Preliminary data suggest SHH inhibitors may help potentiate the effects of radiation therapy for the treatment of BCC. Currently, the evidence primarily is limited to case studies, with several reports describing complete remission in patients with advanced BCCs who were considered unsuitable candidates for surgery. In these cases, vismodegib was administered either prior to or concurrently with radiation treatment.^65-69 An in vitro study also documented the radiation-sensitizing effects of vismodegib in a BCC cell line.⁷⁰ Recently, a phase 2 trial (ClinicalTrials.gov identifier NCT01835626) evaluating the concurrent use of vismodegib and radiotherapy for patients with advanced BCC was completed, but data has yet to be published.

Synergism With and Benefit of Antifungal Therapy

The antifungal drug itraconazole is a potent inhibitor of the SHH pathway and may have an adjunctive role in the treatment of BCC. Similar to vismodegib and sonidegib, itraconazole acts as a direct antagonist of SMO. However, it is thought to bind to a distinct site on SMO.^71,72 An open-label, exploratory phase 2 trial of 19 patients with BCC found that oral itraconazole 200 to 400 mg daily decreased tumor proliferative index by 45% (P=.04), as measured by Ki-67; SHH activity by 65% (P=.03), as measured by GLI1 messenger RNA; and mean tumor area by 24%.⁷³ In a case series of 5 patients with mBCC refractory to conventional SHH inhibitor therapy, combined treatment with itraconazole and arsenic trioxide resulted in stable disease and a 75% reduction in SHH activity (P<.001).⁷⁴ One case report documented tumor regression leading to stable disease for 15 months in a patient with laBCC treated with itraconazole monotherapy due to being unable to afford vismodegib or sonidegib. However, within 2 months of treatment discontinuation, the lesion progressed considerably.⁷⁵ The efficacy of a topical formulation of itraconazole also has been tested in an open-label, placebo-controlled phase 2 trial, but no benefit was observed.⁷⁶

Posaconazole is a second-generation antifungal agent that may serve as a potential alternative to itraconazole.⁷⁷ Although clinical data are lacking, a basic science study found that posaconazole could inhibit the growth of SHH-dependent BCC in vivo (in mice).⁷⁸ Furthermore, posaconazole has demonstrated a better safety profile with fewer and more mild side effects than itraconazole and does not require dose adjustment for those with hepatic or renal failure.^79,80 Thus, posaconazole may be a safer alternative to itraconazole for the treatment of BCC. Further clinical studies are needed to elucidate the potential synergistic effects of these antifungal agents with the 2 currently approved SHH inhibitors for the treatment of advanced BCC.

Treatment resistance to SHH inhibitors, though uncommon, is a growing concern. Acquired mutations in the SMO binding site or downstream mediators of the SHH pathway have been shown to confer resistance to vismodegib and sonidegib.^72,81-83 In addition, it appears that there may be shared resistance among the drugs in this class. One study assessing the efficacy of sonidegib in 9 patients with laBCC resistant to vismodegib found that these patients also did not respond to sonidegib.⁸⁴ Interestingly, 1 case report documented tumor regression of an intracranial BCC in a patient treated with sonidegib and itraconazole after failure with vismodegib.⁸⁵ An in vitro study also found that itraconazole maintained SHH inhibitory activity for all drug-resistant SMO mutations that have been reported.⁷² Therefore, itraconazole monotherapy or combination therapy with a canonical SHH inhibitor may be considered for patients with recalcitrant BCC and warrants further investigation.

Taladegib is a newly developed SMO inhibitor that may serve as another promising alternative for patients who develop resistance to vismodegib or sonidegib. A phase 1 trial of taladegib for advanced BCC found an ORR of 69% (11/16) in the SHH inhibitor–naïve group and an ORR of 36% (11/32) in the group previously treated with a SHH inhibitor.⁸⁶ Additionally, the safety profile and frequency of adverse effects appear to be similar to those associated with vismodegib and sonidegib.^86,87 Unfortunately, no clinical trials evaluating taladegib for BCC are ongoing or in development at this time.

Recurrence

There appears to be a relatively high rate of recurrence for BCC patients who achieve a CR to SHH inhibitors. In a retrospective study of 116 laBCC patients who experienced a CR after vismodegib therapy, 54 patients (47%) relapsed at 36 months. Among the 54 patients that relapsed, 27 were re-treated with vismodegib, which resulted in an ORR of 85% (23/27), a CR rate of 37% (10/27), and a PR rate of 48% (13/27).⁸⁸ Another retrospective study of 35 laBCC patients who relapsed after vismodegib treatment reported a 31% (11/35) clinical recurrence rate at 6-month follow-up.⁸⁹ An observational retrospective study also assessed the efficacy of SHH inhibitor maintenance therapy for advanced BCC patients who achieved a CR.⁹⁰ In the study, 27 (64%) patients received a maintenance dose of 150 mg vismodegib once per week for 1 year, while 15 (36%) patients decided not to take a maintenance dose following CR of their BCC. All patients who took the maintenance therapy did not experience clinical recurrence at 1-year follow-up, whereas 26% of patients not on the maintenance dose relapsed.⁹⁰ Consequently, these results indicate that BCC recurrence is frequent after SHH inhibitor therapy and highlights the importance of close surveillance after CR is attained. Nevertheless, most patients still respond to treatment with SHH inhibitors after relapsing, and intermittent maintenance doses may be an effective means to reduce risk of recurrence.

Conclusion

Vismodegib and sonidegib are SHH inhibitors approved for the treatment of laBCC and mBCC. Cemiplimab is now also approved for patients who do not respond to SHH inhibitors or for whom SHH inhibitors are not tolerable. Although these systemic targeted therapies can lead to notable tumor shrinkage and even complete regression in some patients, recurrence is common, and adverse effects may limit their use.

Although SHH inhibitors and PD-1 inhibitors represent a major advancement in the field of oncodermatology, real-world efficacy and safety data in the upcoming years will be important for elucidating their true benefit for patients with BCC.

Basal cell carcinoma (BCC) is the most common keratinocyte carcinoma and affects more than 3 million individuals per year in the United States.¹ Approximately 40% of patients diagnosed with BCC will develop another BCC within 5 years of the initial diagnosis.² Most cases are successfully treated with surgical excision and occasionally topical therapy or radiotherapy. Despite the high cure rate with conventional treatments, BCC can recur and can cause substantial destruction of the surrounding tissue if left untreated.^3-5 In some instances, BCC can even metastasize and lead to death.⁶ For patients who are poor candidates for surgical or topical treatment modalities because of locally advanced BCC (laBCC) or metastatic BCC (mBCC), systemic treatment may be indicated. Vismodegib, sonidegib, and cemiplimab are the only systemic medications approved by the US Food and Drug Administration (FDA) for the treatment of laBCC and/or mBCC. Vismodegib and sonidegib target the sonic hedgehog (SHH) signaling pathway that is abnormally activated in more than 90% of BCCs.⁷ Cemiplimab is an immune checkpoint inhibitor (ICI) that targets the programmed cell death protein 1 (PD-1) receptor.⁸ Herein, we review the clinical utility of these medications and their evolving roles in the treatment of BCC.

SHH Pathway Inhibitors

The SHH pathway is a key regulator of cell proliferation and differentiation during embryogenesis.⁷ During adulthood, SHH signaling decreases but still plays an important role in stem cell activation and in regulation of the hair follicle growth cycle.^9,10 However, de novo mutations in the genes that comprise the SHH pathway can result in aberrant constitutive activation, leading to unrestricted cell proliferation. Genetic mutations resulting in activation of Smoothened (SMO), a G-protein–coupled receptor involved in the signal transduction and propagation of the SHH pathway, have been implicated in the pathogenesis of BCC. Inactivating mutations also are commonly observed in patched homolog 1, an upstream cell-surface protein that inhibits SMO.⁷ The mechanism by which vismodegib and sonidegib, 2 of the FDA-approved oral medications for the treatment of advanced BCC, block the SHH pathway is through the selective inhibition of SMO.^7,11

Vismodegib first received FDA approval in 2012 for the treatment of laBCC and mBCC after initial results from the pivotal ERIVANCE phase 2 trial demonstrated an objective response rate (ORR) of 43% (27/63) and 30% (10/33) in patients with locally advanced and metastatic disease, respectively. In this single-arm study, all enrolled patients (63 with laBCC and 33 with mBCC) received 150 mg of oral vismodegib daily.¹² Updated results at 39 months demonstrated improved ORRs of 60% (38/63) and 48% (16/33) for the laBCC and mBCC groups, respectively. A complete response (CR) and partial response (PR) were observed in 32% (n=20) and 29% (n=18) of patients with laBCC, respectively.¹³ These results have been confirmed in subsequent studies, including the large international open-label trial known as STEVIE, with ORRs of 68.5% for 1119 cases of laBCC and 37% for 96 cases of mBCC.^14-17 The CR and PR rates were 33% and 35%, respectively, for the laBCC group. The CR and PR rates for the mBCC group were 5% and 32%, respectively.¹⁴

The FDA approval of sonidegib for laBCC—but not mBCC—occurred in 2015 after the pivotal BOLT randomized phase 2 trial demonstrated an initial ORR of 43% (18/42) for laBCC and 15% (2/13) for mBCC after administration of 200 mg of sonidegib daily.¹⁸ A final follow-up analysis at 42 months resulted in ORRs of 56% (37/66) and 8% (1/13) for the laBCC and mBCC groups, respectively.¹⁹ Additionally, improved efficacy was not observed in the 151 patients who were randomized to receive treatment with the higher 800-mg dose; however, they did experience a higher incidence of adverse events.^18,19

Currently, the true clinical differences between vismodegib and sonidegib remain uncertain, as no head-to-head trials have been conducted. Moreover, direct comparison of the data from the ERIVANCE and BOLT trials is challenging owing to fundamental differences in methodologic design, including the criteria used to assess BCC severity. The ERIVANCE trial utilized the conventional Response Evaluation Criteria in Solid Tumors (RECIST), while BOLT used the rigorous modified RECIST. However, an expert consensus study attempted to compare the 2 trials by modifying the outcomes from BOLT with the former RECIST criteria. The expert group found that the 2 SHH inhibitors had comparable efficacy and adverse event profiles.²⁰ Nevertheless, a recent meta-analysis found that although ORRs for laBCC were similar between the 2 drugs, the CR rate for vismodegib was 31% compared with 3% for sonidegib. Additionally, for mBCC, they reported the ORR of vismodegib to be 2.7 times higher than that of sonidegib (39% vs 15%).²¹

Immune Checkpoint Inhibitors

Immune checkpoint inhibitors have successfully been utilized in the treatment of cutaneous squamous cell carcinoma (cSCC); however, their use for treating BCC has been limited until recently.^22-25 In February 2021, cemiplimab became the first and only ICI approved for the treatment of laBCC and mBCC in patients who did not respond to or were intolerant to prior SHH inhibitor therapy.²⁶ Cemiplimab—a human monoclonal antibody against the PD-1 receptor expressed on T cells—blocks its interaction with programmed cell death ligand 1 and programmed cell death ligand 2 present on tumor cells. The blockade of the PD-1 pathway releases the inhibition of the antitumor immune response and enables appropriate cytotoxic T-cell activity to occur.⁸

The FDA approval of cemiplimab for the treatment of advanced BCC was based on an open-label, multicenter, single-arm phase 2 trial (NCT03132636) evaluating 84 patients with laBCC refractory or intolerant to SHH inhibitor therapy.²⁶ Patients received an intravenous infusion of cemiplimab 350 mg every 3 weeks for up to 93 weeks or until disease progression or unacceptable toxicity. An ORR of 31% (26/84) was observed with a CR and PR of 6% (5/84) and 25% (21/84), respectively. The median duration of follow-up was 15 months.²⁶ Given the clinically meaningful results of this trial, investigating the efficacy of other PD-1 inhibitors, such as pembrolizumab and nivolumab, for treatment of advanced BCC may prove worthwhile.

The 2 approved SHH inhibitors—vismodegib and sonidegib—appear to have similar side-effect profiles, with the most common adverse effects being muscle spasms, dysgeusia, alopecia, nausea, vomiting, diarrhea, weight loss, and fatigue.^20,21,27 These side effects occur at high frequencies (>40%) for both SHH inhibitors and often lead to discontinuation of the medication.²¹ Rates of treatment discontinuation range from 15% to 50% on average.^12-14,18 Fortunately, the majority of these adverse effects do not appear to increase in severity or frequency with prolonged use of these medications.^14,16,28

Various conservative and pharmacologic measures can be implemented to help manage side effects. For muscle spasms, which are the most commonly reported adverse effect, supplementation with magnesium, transcutaneous electrical nerve stimulation, acupuncture, massages, stretching, and thermal compresses can potentially be beneficial.²⁹ Calcium channel blockers also may be effective, as one small prospective cohort study reported a reduction in the frequency of muscle cramps with amlodipine 10 mg daily.³⁰ For alopecia, which typically is reversible and caused by SHH inhibition of the normal hair cycle, minoxidil theoretically can help, as it reduces telogen arrest and extends the anagen growth phase.^31,32 Although usually mild and self-limiting, management of dysgeusia, weight loss, and gastrointestinal upset often can be managed with dietary changes, such as smaller, more frequent meals.^33,34 Finally, alternative dosing strategies and drug holidays have been employed to mitigate these side effects and increase drug tolerability.^35,36 These are discussed in the Alternative Dosing section.

Given the essential role of the SHH pathway in embryologic development, SHH inhibitors carry a black box warning of embryofetal teratogenicity and are contraindicated in females who are pregnant or breastfeeding. For females of reproductive potential, verification of pregnancy status should be performed prior to initiating treatment with an SHH inhibitor. These patients should be counseled on the use of contraception during treatment and for at least 24 months and 20 months after cessation of vismodegib and sonidegib, respectively.^27,37,38 Male patients, even after a vasectomy, should use barrier contraception during treatment and for at least 3 months and 8 months after the final dose of vismodegib and sonidegib, respectively.^37,38

Laboratory abnormalities commonly associated with SHH inhibitors include elevated hepatic enzymes, particularly with vismodegib, and elevated creatine kinase levels, particularly with sonidegib.^28,39 Other laboratory abnormalities that can occur include hypercholesterolemia, hypercreatininemia, hyperglycemia, and increased serum lipase levels.^19,28 Although these laboratory abnormalities usually are asymptomatic and self-limiting, regular monitoring should be performed.

There also is concern that SHH inhibitors may induce the development of cSCC. A case-control study of 55 cases and 125 control patients found an increased risk for cSCC in those previously treated with vismodegib, with a hazard ratio of 8.12.⁴⁰ However, a subsequent retrospective cohort study of 1675 patients with BCC failed to find any association with cSCC among those treated with vismodegib compared to those who received standard surgical therapy.⁴¹ Clinical data for sonidegib are lacking, but the BOLT trial found that cSCC occurred in 3 patients receiving treatment with the SHH inhibitor.¹⁸ Thus, further studies are needed to more thoroughly assess this concern. Close monitoring for cSCC may be warranted in patients prescribed SHH inhibitors at this time.

Cemiplimab has demonstrated an acceptable safety profile and is generally well tolerated. In the phase 2 trial of cemiplimab for cSCC, approximately 5% of patients discontinued treatment because of adverse effects. The most commonly reported side effects of cemiplimab were diarrhea (27%), fatigue (24%), nausea (17%), constipation (15%), and rash (15%).²³ In the phase 2 trial for laBCC, grade 3 or 4 adverse events occurred in 48% of patients, with hypertension (5%) being the most common.²⁶ Although rare, immune-mediated adverse reactions also can occur, given the mechanism of action of ICIs. These side effects, ranging in severity from mild to fatal, include pneumonitis, colitis, hepatitis, nephritis, myocarditis, and hypophysitis. Therefore, close monitoring for these immune-mediated reactions is critical, but most can be managed with corticosteroids or treatment interruption if they occur.^42,43

No absolute contraindications exist for cemiplimab; however, extreme caution should be taken in immunosuppressed individuals, such as solid organ transplant recipients and those with chronic lymphocytic leukemia (CLL), as safety data are limited in these patients.^44,45 Although small retrospective studies have reported reasonable tolerability in solid organ transplant recipients treated with ICIs, an allograft rejection rate of 41% was found in a meta-analysis of 64 patients.^46-48 In CLL patients with keratinocyte carcinomas, ICIs have been safely used and have even demonstrated efficacy for CLL in some cases.^49-52

Alternative Dosing

The side effects of SHH inhibitors have led to alternative dosing strategies to prevent medication discontinuation and improve adherence. In patients with basal cell nevus syndrome, multimonth drug holidays have been shown to increase drug tolerability without compromising efficacy.^35,36 Weekly intermittent dosing regimens of vismodegib ranging from 1 week on followed by 1 to 3 weeks off demonstrated efficacy in a retrospective study of 7 patients with advanced BCC.⁵³ All 7 patients experienced improvement in their BCCs, with 3 patients experiencing CR. Importantly, treatment-related adverse effects were mild and well tolerated, with no patients terminating the medication.⁵³ Two other retrospective case series of patients with advanced BCC treated with vismodegib reported similar findings for those placed on an intermittent dosing schedule ranging from once every other day to once per week.^54,55

In the large phase 2 randomized trial known as MIKIE, 2 different intermittent dosing regimens of 150 mg vismodegib daily for patients with multiple BCCs were found to have good activity and tolerability.⁵⁶ The first group (n=116) received vismodegib for 12 weeks, then 3 rounds of 8 weeks of placebo, followed by 12 weeks of vismodegib; there was a 63% reduction in clinically evident BCCs after 73 weeks. The second group (n=113) received the medication for 24 weeks, then 3 rounds of 8 weeks of placebo, followed by 8 weeks of vismodegib; there was a 54% reduction at the end of 73 weeks.⁵⁶ Subsequent analyses found improvements in health-related quality-of-life outcomes that were similar for both groups.⁵⁷

Consequently, alternative dosing schedules appear to be a viable option for patients at risk of discontinuing treatment because of adverse effects, and current data support the recently approved recommendations of dose interruptions of up to 8 weeks to manage adverse effects in patients with laBCC or mBCC.⁵⁸ Nevertheless, further clinical studies are required to determine the optimal intermittent dosing regimen for patients treated with SHH inhibitors.

Neoadjuvant Administration

Recently, vismodegib has been studied as a neoadjuvant therapy for BCC with promising results. Several small retrospective studies and case reports have documented successful treatment of both operable and inoperable periocular laBCC, with preservation of the eye in all patients.^59-61 An open-label trial of 15 patients with advanced BCC who received neoadjuvant vismodegib for 3 to 6 months prior to surgical excision reported a mean reduction of 35% in the final surgical defect size, with no recurrence at 22 months.^62,63 The latest and largest study performed was a phase 2 open-label trial known as VISMONEO, where 44 of 55 laBCC patients (80%) receiving neoadjuvant vismodegib for a mean duration of 6 months (range, 4–10 months) achieved the primary end point of tumor surgical downstaging.⁶⁴ Of the 44 patients who had tumor downstaging, 27 (61%) experienced histologically proven CRs. Additionally, a 66% reduction in the average target lesion size was reported in this group compared to29% in the 11 patients who did not have tumor downstaging (P=.0002).⁶⁴ Thus, SHH inhibitors may hold an important neoadjuvant role in the treatment of BCC by decreasing surgical defect size and allowing for surgical management of previously inoperable cases.

Synergism With Radiation

Preliminary data suggest SHH inhibitors may help potentiate the effects of radiation therapy for the treatment of BCC. Currently, the evidence primarily is limited to case studies, with several reports describing complete remission in patients with advanced BCCs who were considered unsuitable candidates for surgery. In these cases, vismodegib was administered either prior to or concurrently with radiation treatment.^65-69 An in vitro study also documented the radiation-sensitizing effects of vismodegib in a BCC cell line.⁷⁰ Recently, a phase 2 trial (ClinicalTrials.gov identifier NCT01835626) evaluating the concurrent use of vismodegib and radiotherapy for patients with advanced BCC was completed, but data has yet to be published.

Synergism With and Benefit of Antifungal Therapy

The antifungal drug itraconazole is a potent inhibitor of the SHH pathway and may have an adjunctive role in the treatment of BCC. Similar to vismodegib and sonidegib, itraconazole acts as a direct antagonist of SMO. However, it is thought to bind to a distinct site on SMO.^71,72 An open-label, exploratory phase 2 trial of 19 patients with BCC found that oral itraconazole 200 to 400 mg daily decreased tumor proliferative index by 45% (P=.04), as measured by Ki-67; SHH activity by 65% (P=.03), as measured by GLI1 messenger RNA; and mean tumor area by 24%.⁷³ In a case series of 5 patients with mBCC refractory to conventional SHH inhibitor therapy, combined treatment with itraconazole and arsenic trioxide resulted in stable disease and a 75% reduction in SHH activity (P<.001).⁷⁴ One case report documented tumor regression leading to stable disease for 15 months in a patient with laBCC treated with itraconazole monotherapy due to being unable to afford vismodegib or sonidegib. However, within 2 months of treatment discontinuation, the lesion progressed considerably.⁷⁵ The efficacy of a topical formulation of itraconazole also has been tested in an open-label, placebo-controlled phase 2 trial, but no benefit was observed.⁷⁶

Posaconazole is a second-generation antifungal agent that may serve as a potential alternative to itraconazole.⁷⁷ Although clinical data are lacking, a basic science study found that posaconazole could inhibit the growth of SHH-dependent BCC in vivo (in mice).⁷⁸ Furthermore, posaconazole has demonstrated a better safety profile with fewer and more mild side effects than itraconazole and does not require dose adjustment for those with hepatic or renal failure.^79,80 Thus, posaconazole may be a safer alternative to itraconazole for the treatment of BCC. Further clinical studies are needed to elucidate the potential synergistic effects of these antifungal agents with the 2 currently approved SHH inhibitors for the treatment of advanced BCC.

Treatment resistance to SHH inhibitors, though uncommon, is a growing concern. Acquired mutations in the SMO binding site or downstream mediators of the SHH pathway have been shown to confer resistance to vismodegib and sonidegib.^72,81-83 In addition, it appears that there may be shared resistance among the drugs in this class. One study assessing the efficacy of sonidegib in 9 patients with laBCC resistant to vismodegib found that these patients also did not respond to sonidegib.⁸⁴ Interestingly, 1 case report documented tumor regression of an intracranial BCC in a patient treated with sonidegib and itraconazole after failure with vismodegib.⁸⁵ An in vitro study also found that itraconazole maintained SHH inhibitory activity for all drug-resistant SMO mutations that have been reported.⁷² Therefore, itraconazole monotherapy or combination therapy with a canonical SHH inhibitor may be considered for patients with recalcitrant BCC and warrants further investigation.

Taladegib is a newly developed SMO inhibitor that may serve as another promising alternative for patients who develop resistance to vismodegib or sonidegib. A phase 1 trial of taladegib for advanced BCC found an ORR of 69% (11/16) in the SHH inhibitor–naïve group and an ORR of 36% (11/32) in the group previously treated with a SHH inhibitor.⁸⁶ Additionally, the safety profile and frequency of adverse effects appear to be similar to those associated with vismodegib and sonidegib.^86,87 Unfortunately, no clinical trials evaluating taladegib for BCC are ongoing or in development at this time.

Recurrence

There appears to be a relatively high rate of recurrence for BCC patients who achieve a CR to SHH inhibitors. In a retrospective study of 116 laBCC patients who experienced a CR after vismodegib therapy, 54 patients (47%) relapsed at 36 months. Among the 54 patients that relapsed, 27 were re-treated with vismodegib, which resulted in an ORR of 85% (23/27), a CR rate of 37% (10/27), and a PR rate of 48% (13/27).⁸⁸ Another retrospective study of 35 laBCC patients who relapsed after vismodegib treatment reported a 31% (11/35) clinical recurrence rate at 6-month follow-up.⁸⁹ An observational retrospective study also assessed the efficacy of SHH inhibitor maintenance therapy for advanced BCC patients who achieved a CR.⁹⁰ In the study, 27 (64%) patients received a maintenance dose of 150 mg vismodegib once per week for 1 year, while 15 (36%) patients decided not to take a maintenance dose following CR of their BCC. All patients who took the maintenance therapy did not experience clinical recurrence at 1-year follow-up, whereas 26% of patients not on the maintenance dose relapsed.⁹⁰ Consequently, these results indicate that BCC recurrence is frequent after SHH inhibitor therapy and highlights the importance of close surveillance after CR is attained. Nevertheless, most patients still respond to treatment with SHH inhibitors after relapsing, and intermittent maintenance doses may be an effective means to reduce risk of recurrence.

Conclusion

Vismodegib and sonidegib are SHH inhibitors approved for the treatment of laBCC and mBCC. Cemiplimab is now also approved for patients who do not respond to SHH inhibitors or for whom SHH inhibitors are not tolerable. Although these systemic targeted therapies can lead to notable tumor shrinkage and even complete regression in some patients, recurrence is common, and adverse effects may limit their use. Drug resistance is an emerging issue that requires additional examination. Further clinical studies are needed to determine which patients are likely to respond to these targeted treatments.

Various intermittent and maintenance drug regimens should be evaluated for their potential to mitigate adverse effects and reduce risk of recurrence, respectively. The synergistic effects of these medications with other therapies as well as their neoadjuvant and adjuvant roles should be further investigated. For example, administration of an SHH inhibitor prior to surgical excision of a BCC may allow for a smaller surgical defect size, thereby improving cosmetic and functional outcomes. Moreover, these systemic targeted medications may allow for previously inoperable tumors to become amenable to surgical treatment.

Although SHH inhibitors and PD-1 inhibitors represent a major advancement in the field of oncodermatology, real-world efficacy and safety data in the upcoming years will be important for elucidating their true benefit for patients with BCC.

As states ban or limit abortion in the wake of the demise of Roe v. Wade, physicians are turning their attention to widely-used drugs that can cause birth defects. At issue: Should these drugs still be prescribed to women of childbearing age if they don’t have the option of terminating their pregnancies?

“Doctors are going to understandably be terrified that a patient may become pregnant using a teratogen that they have prescribed,” said University of Pittsburgh rheumatologist Mehret Birru Talabi, MD, PhD, who works in a state where the future of abortion rights is uncertain. “While this was a feared outcome before Roe v. Wade was overturned, abortion provided an escape hatch by which women could avoid having to continue a pregnancy and potentially raise a child with congenital anomalies. I believe that prescribing is going to become much more defensive and conservative. Some clinicians may choose not to prescribe these medications to patients who have childbearing potential, even if they don’t have much risk for pregnancy.”

Other physicians expressed similar concerns in interviews. Duke University, Durham, N.C., rheumatologist Megan E. B. Clowse, MD, MPH, fears that physicians will be wary of prescribing a variety of medications – including new ones for which there are few pregnancy data – if abortion is unavailable. “Women who receive these new or teratogenic medications will likely lose their reproductive autonomy and be forced to choose between having sexual relationships with men, obtaining procedures that make them permanently sterile, or using contraception that may cause intolerable side effects,” she said. “I am very concerned that young women with rheumatic disease will now be left with active disease resulting in joint damage and renal failure.”

Abortion is now banned in at least six states, according to The New York Times. That number may rise to 16 as more restrictions become law. Another five states aren’t expected to ban abortion soon but have implemented gestational age limits on abortion or are expected to adopt them. In another nine states, courts or lawmakers will decide whether abortion remains legal.

Only 20 states and the District of Columbia have firm abortion protections in place.

Numerous drugs are considered teratogens, which means they may cause birth defects. Thalidomide is the most infamous, but there are many more, including several used in rheumatology, dermatology, and gastroenterology. Among the most widely used teratogenic medications are the acne drugs isotretinoin and methotrexate, which are used to treat a variety of conditions, such as cancer, rheumatoid arthritis, and psoriasis.

Dr. Clowse, who helps manage an industry-supported website devoted to reproductive care for women with lupus (www.LupusPregnancy.org), noted that several drugs linked to birth defects and pregnancy loss are commonly prescribed in rheumatology.

“Methotrexate is the most common medication and has been the cornerstone of rheumatoid arthritis [treatment] for at least two decades,” she said. “Mycophenolate is our best medication to treat lupus nephritis, which is inflammation in the kidneys caused by lupus. This is a common complication for young women with lupus, and all of our guideline-recommended treatment regimens include a medication that causes pregnancy loss and birth defects, either mycophenolate or cyclophosphamide.”

Rheumatologists also prescribe a large number of new drugs for which there are few data about pregnancy risks. “It typically takes about two decades to have sufficient data about the safety of our medications,” she said.

Reflecting the sensitivity of the topic, Dr. Clowse made clear that her opinions don’t represent the views of her institution. She works in North Carolina, where the fate of abortion rights is uncertain, according to The New York Times.

What about alternatives? “The short answer is that some of these medications work really well and sometimes much better than the nonteratogenic alternatives,” said Dr. Birru Talabi. “I’m worried about methotrexate. It has been used to induce abortions but is primarily used in the United States as a highly effective treatment for cancer as well as a myriad of rheumatic diseases. If legislators try to restrict access to methotrexate, we may see increasing disability and even death among people who need this medication but cannot access it.”

Rheumatologists aren’t the only physicians who are worrying about the fates of their patients in a new era of abortion restrictions. Gastroenterologist Sunanda Kane, MD, MSPH, of the Mayo Clinic, Rochester, Minn., said several teratogenic medications are used in her field to treat constipation, viral hepatitis, and inflammatory bowel disease.

“When treating women of childbearing age, there are usually alternatives. If we do prescribe a medication with a high teratogenic potential, we counsel and document that we have discussed two forms of birth control to avoid pregnancy. We usually do not prescribe a drug with teratogenic potential with the ‘out’ being an abortion if a pregnancy does occur,” she said. However, “if abortion is not even on the table as an option, we may be much less likely to prescribe these medications. This will be particularly true in patients who clearly do not have the means to travel to have an abortion in any situation.”

Abortion is expected to remain legal in Minnesota, where Dr. Kane practices, but it may be restricted or banned in nearby Wisconsin, depending on the state legislature. None of her patients have had abortions after becoming pregnant while taking the medications, she said, although she “did have a patient who because of her religious faith did not have an abortion after exposure and ended up with a stillbirth.”

The crackdown on abortion won’t just pose risks to patients who take potentially dangerous medications, physicians said. Dr. Kane said pregnancy itself is a significant risk for patients with “very active, uncontrolled gastrointestinal conditions where a pregnancy could be harmful to the mother’s health or result in offspring that are very unhealthy.” These include decompensated cirrhosis, uncontrolled Crohn’s disease or ulcerative colitis, refractory gastroparesis, uncontrolled celiac sprue, and chronic pancreatitis, she said.

“There have been times when after shared decisionmaking, a patient with very active inflammatory bowel disease has decided to terminate the pregnancy because of her own ongoing health issues,” she said. “Not having this option will potentially lead to disastrous results.”

Dr. Clowse, the Duke University rheumatologist, echoed Dr. Kane’s concerns about women who are too sick to bear children. “The removal of abortion rights puts the lives and quality of life for women with rheumatic disease at risk. For patients with lupus and other systemic rheumatic disease, pregnancy can be medically catastrophic, leading to permanent harm and even death to the woman and her offspring. I am worried that women in these conditions will die without lifesaving pregnancy terminations, due to worries about the legal consequences for their physicians.”

The U.S. Supreme Court’s ruling that overturned Roe v. Wade has also raised the prospect that the court could ultimately allow birth control to be restricted or outlawed.

While the ruling states that “nothing in this opinion should be understood to cast doubt on precedents that do not concern abortion,” Justice Clarence Thomas wrote a concurrence in which he said that the court should reconsider a 1960s ruling that forbids the banning of contraceptives. Republicans have dismissed concerns about bans being allowed, although Democrats, including the president and vice president, starkly warn that they could happen.

“If we as providers have to be concerned that there will be an unplanned pregnancy because of the lack of access to contraception,” Dr. Kane said, “this will have significant downstream consequences to the kind of care we can provide and might just drive some providers to not give care to female patients at all given this concern.”

Dr. Kane said pregnancy itself is a significant risk for patients with “very active, uncontrolled gastrointestinal conditions where a pregnancy could be harmful to the mother’s health or result in offspring that are very unhealthy.” These include decompensated cirrhosis, uncontrolled Crohn’s disease or ulcerative colitis, refractory gastroparesis, uncontrolled celiac sprue, and chronic pancreatitis, she said.

“There have been times when after shared decisionmaking, a patient with very active inflammatory bowel disease has decided to terminate the pregnancy because of her own ongoing health issues,” she said. “Not having this option will potentially lead to disastrous results.”

Dr. Clowse, the Duke University rheumatologist, echoed Dr. Kane’s concerns about women who are too sick to bear children. “The removal of abortion rights puts the lives and quality of life for women with rheumatic disease at risk. For patients with lupus and other systemic rheumatic disease, pregnancy can be medically catastrophic, leading to permanent harm and even death to the woman and her offspring. I am worried that women in these conditions will die without lifesaving pregnancy terminations, due to worries about the legal consequences for their physicians.”

The U.S. Supreme Court’s ruling that overturned Roe v. Wade has also raised the prospect that the court could ultimately allow birth control to be restricted or outlawed.

While the ruling states that “nothing in this opinion should be understood to cast doubt on precedents that do not concern abortion,” Justice Clarence Thomas wrote a concurrence in which he said that the court should reconsider a 1960s ruling that forbids the banning of contraceptives. Republicans have dismissed concerns about bans being allowed, although Democrats, including the president and vice president, starkly warn that they could happen.

“If we as providers have to be concerned that there will be an unplanned pregnancy because of the lack of access to contraception,” Dr. Kane said, “this will have significant downstream consequences to the kind of care we can provide and might just drive some providers to not give care to female patients at all given this concern.”

As states ban or limit abortion in the wake of the demise of Roe v. Wade, physicians are turning their attention to widely-used drugs that can cause birth defects. At issue: Should these drugs still be prescribed to women of childbearing age if they don’t have the option of terminating their pregnancies?

“Doctors are going to understandably be terrified that a patient may become pregnant using a teratogen that they have prescribed,” said University of Pittsburgh rheumatologist Mehret Birru Talabi, MD, PhD, who works in a state where the future of abortion rights is uncertain. “While this was a feared outcome before Roe v. Wade was overturned, abortion provided an escape hatch by which women could avoid having to continue a pregnancy and potentially raise a child with congenital anomalies. I believe that prescribing is going to become much more defensive and conservative. Some clinicians may choose not to prescribe these medications to patients who have childbearing potential, even if they don’t have much risk for pregnancy.”

Other physicians expressed similar concerns in interviews. Duke University, Durham, N.C., rheumatologist Megan E. B. Clowse, MD, MPH, fears that physicians will be wary of prescribing a variety of medications – including new ones for which there are few pregnancy data – if abortion is unavailable. “Women who receive these new or teratogenic medications will likely lose their reproductive autonomy and be forced to choose between having sexual relationships with men, obtaining procedures that make them permanently sterile, or using contraception that may cause intolerable side effects,” she said. “I am very concerned that young women with rheumatic disease will now be left with active disease resulting in joint damage and renal failure.”

Abortion is now banned in at least six states, according to The New York Times. That number may rise to 16 as more restrictions become law. Another five states aren’t expected to ban abortion soon but have implemented gestational age limits on abortion or are expected to adopt them. In another nine states, courts or lawmakers will decide whether abortion remains legal.

Only 20 states and the District of Columbia have firm abortion protections in place.

Numerous drugs are considered teratogens, which means they may cause birth defects. Thalidomide is the most infamous, but there are many more, including several used in rheumatology, dermatology, and gastroenterology. Among the most widely used teratogenic medications are the acne drugs isotretinoin and methotrexate, which are used to treat a variety of conditions, such as cancer, rheumatoid arthritis, and psoriasis.

Dr. Clowse, who helps manage an industry-supported website devoted to reproductive care for women with lupus (www.LupusPregnancy.org), noted that several drugs linked to birth defects and pregnancy loss are commonly prescribed in rheumatology.

“Methotrexate is the most common medication and has been the cornerstone of rheumatoid arthritis [treatment] for at least two decades,” she said. “Mycophenolate is our best medication to treat lupus nephritis, which is inflammation in the kidneys caused by lupus. This is a common complication for young women with lupus, and all of our guideline-recommended treatment regimens include a medication that causes pregnancy loss and birth defects, either mycophenolate or cyclophosphamide.”

Rheumatologists also prescribe a large number of new drugs for which there are few data about pregnancy risks. “It typically takes about two decades to have sufficient data about the safety of our medications,” she said.

Reflecting the sensitivity of the topic, Dr. Clowse made clear that her opinions don’t represent the views of her institution. She works in North Carolina, where the fate of abortion rights is uncertain, according to The New York Times.

What about alternatives? “The short answer is that some of these medications work really well and sometimes much better than the nonteratogenic alternatives,” said Dr. Birru Talabi. “I’m worried about methotrexate. It has been used to induce abortions but is primarily used in the United States as a highly effective treatment for cancer as well as a myriad of rheumatic diseases. If legislators try to restrict access to methotrexate, we may see increasing disability and even death among people who need this medication but cannot access it.”

Rheumatologists aren’t the only physicians who are worrying about the fates of their patients in a new era of abortion restrictions. Gastroenterologist Sunanda Kane, MD, MSPH, of the Mayo Clinic, Rochester, Minn., said several teratogenic medications are used in her field to treat constipation, viral hepatitis, and inflammatory bowel disease.

“When treating women of childbearing age, there are usually alternatives. If we do prescribe a medication with a high teratogenic potential, we counsel and document that we have discussed two forms of birth control to avoid pregnancy. We usually do not prescribe a drug with teratogenic potential with the ‘out’ being an abortion if a pregnancy does occur,” she said. However, “if abortion is not even on the table as an option, we may be much less likely to prescribe these medications. This will be particularly true in patients who clearly do not have the means to travel to have an abortion in any situation.”

Abortion is expected to remain legal in Minnesota, where Dr. Kane practices, but it may be restricted or banned in nearby Wisconsin, depending on the state legislature. None of her patients have had abortions after becoming pregnant while taking the medications, she said, although she “did have a patient who because of her religious faith did not have an abortion after exposure and ended up with a stillbirth.”

The crackdown on abortion won’t just pose risks to patients who take potentially dangerous medications, physicians said.

The Diagnosis: Lymphomatoid Papulosis

At the time of the initial visit, a punch biopsy was performed on the posterior shoulder girdle. Histopathology revealed mild epidermal spongiosis and acanthosis with associated parakeratosis and a dermal lymphocytic infiltrate with extravasated erythrocytes consistent with pityriasis rosea (Figure 1). Two weeks after the biopsy, the patient returned for suture removal and to discuss the biopsy results. The patient reported more evolving lesions despite completing the prescribed course of dicloxacillin. At this time, physical examination revealed the persistence of several reddishbrown papules along with new nodular lesions on the arms and thighs, some with central ulceration and crusting (Figure 2). A second biopsy of a nodular lesion on the right distal forearm was performed at this visit along with a superficial tissue culture, which was negative for bacterial or fungal elements. The biopsy revealed an atypical CD30⁺ lymphoid proliferation (Figure 3). These cells were strongly PD-L1 positive and also positive for CD3, CD4, and granzyme-B. Ki67 showed a high proliferation rate, and T-cell gene rearrangement studies were positive. Given these histologic findings and the clinical context of rapidly evolving skin lesions from small papules to nodular skin tumors, a diagnosis of lymphomatoid papulosis (LyP) was established.

Because of the notable pathologic discordance between the 2 biopsy specimens, re-evaluation of the initial specimen was requested. The initial biopsy was subsequently found to be CD30⁺ with an identical peak on gene rearrangement studies as the second biopsy, further validating the diagnosis of LyP (Figure 4). Our patient was offered low-dose methotrexate therapy but declined the treatment plan, as the skin lesions had begun to resolve.

Lymphomatoid papulosis is a chronic CD30⁺ lymphoproliferative disorder with a characteristic recurrent and self-remitting disease course.^1,2 Although it typically has a benign clinical course, it is histologically malignant and considered a low-grade variant of cutaneous T-cell lymphoma. ^2,3 The classic clinical presentation of LyP involves the presence of reddish-brown papules and nodules typically measuring less than 2.0 cm, which may show evidence of central ulceration, hemorrhage, necrosis, and/or crust formation.^1-5 It is characteristic that a patient may present with these skin lesions in different stages of evolution and that biopsies of these lesions may reflect different histologic features depending on the age of the lesion, making a definitive diagnosis more difficult to obtain if not clinically correlated.^1,2 Any part of the body may be involved; however, there appears to be a predilection for the trunk and extremities in most cases.^1-3,5 The skin eruptions usually are asymptomatic, but pruritus is a commonly associated concern.^1,2,4,5

Lymphomatoid papulosis can have a localized, clustered, or generalized distribution pattern and typically will spontaneously regress without treatment within 3 to 12 weeks of symptom onset.^2,3 Lymphomatoid papulosis has a slight male predominance with a male to female ratio of 1.5:1. It occurs most commonly between 35 and 45 years of age, though it can present at any age. The overall duration of the disease can range from months to decades.^2,3 Lymphomatoid papulosis makes up approximately 15% of all cutaneous T-cell lymphomas.^2,3 Although the overall prognosis is excellent, patients with LyP are at an increased risk of developing cutaneous or systemic lymphoma, most commonly mycosis fungoides, anaplastic large cell lymphoma, or Hodgkin lymphoma.^1-3 This increased lifelong risk is the reason that patients with LyP must be followed long-term every 6 to 12 months for surveillance of emerging malignancy.^1,2,6

The pathogenesis of LyP remains unknown. Some have hypothesized a possible viral trigger; however, there is insufficient data to support this theory.^2,6 A diagnostic hallmark of LyP is its CD30 positivity, which is a known marker for T-cell activation.6 The spontaneous regression of skin lesions that is characteristic of LyP is believed to involve the interactions between CD30 and its ligand (CD30L), which may contribute to apoptosis of neoplastic T cells.^2,3,6 With regards to the possible mechanisms contributing to tumor progression in LyP, a mutation in the transforming growth factor β receptor gene on CD30+ tumor cells within LyP lesions may allow for these cells to evade growth regulation and progress to lymphoma.^2,6 A large percentage of LyP biopsy specimens show evidence of T-cell receptor gene monoclonal rearrangement, which can aid in establishing a diagnosis.^1,2

The histologic features of LyP can vary greatly depending on the age of the lesion sampled.^1,2 Histologic subtypes of LyP have been established, with type A being the most common (approximately 75% of cases), displaying a wedge-shaped infiltrate of scattered or clustered, large, atypical CD30+ T cells.^1,2 Types B through E vary in histologic features, with the exception that all subtypes contain a CD30+ lymphocytic infiltrate.^2,3

Treatment of LyP depends on the symptom/disease burden that the patient is experiencing. For patients with a limited number of nonscarring skin lesions in areas that are not cosmetically sensitive, observation is recommended. ^1-3 For symptomatic patients with an extensive number of lesions, particularly those that may be scarring and/or in cosmetically sensitive areas, low-dose oral methotrexate therapy is considered first-line treatment.^1-4 A methotrexate dose of 5 to 20 mg weekly can be effective in reducing the number and severity of lesions, with duration of treatment depending on clinical response.^1,2 For patients who have contraindications to or who cannot tolerate oral methotrexate, phototherapy using psoralen plus UVA twice weekly for 6 to 8 weeks is another treatment option.^1,2 Topical corticosteroids also can be used in children or for patients experiencing substantial pruritus.^1,2,4 Oral or topical retinoids, topical carmustine or mechlorethamine, and brentuximab (an anti-CD30 monoclonal antibody) are all alternative therapies that have shown some beneficial effects.^1,2 In the event that any of the skin lesions do not spontaneously regress within a 3- to 12-week time frame, surgical excision or radiotherapy can be performed on those lesions.²

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is another CD30+ lymphoproliferative disorder with overlapping clinical and histopathological features of LyP. Recurrent crops of multiple lesions favor a diagnosis of LyP, whereas solitary lesions favor C-ALCL; however, multifocal C-ALCL cases may occur.² Mycosis fungoides is the most common type of cutaneous T-cell lymphoma that characteristically presents in a patch, plaque, tumor progression. Although mycosis fungoides eventually may transform into a CD30⁺ lymphoma, our patient did not display the characteristic clinical progression to suggest this diagnosis. Pityriasis lichenoides et varioliformis acuta and pityriasis lichenoides chronica also fall into the spectrum of clonal T-cell cutaneous disorders that more commonly affect the pediatric population. Pityriasis lichenoides et varioliformis acuta has a marked CD8⁺ lymphocyte infiltrate, whereas pityriasis lichenoides chronica has more CD4⁺ lymphocytes. These disorders typically do not stain positive for CD30.²

All patients with a diagnosis of LyP should maintain lifelong, regular, 6- to 12-month follow-up visits to monitor disease status and screen for any evidence of developing malignancy.^1,2,6 A thorough review of clinical history, complete skin examination, and physical examination with a particular focus on detection of lymphadenopathy and hepatosplenomegaly should be included at every followup visit.1 Systemic symptoms such as fever, night sweats, or weight loss are not typical features of LyP; therefore, patients who begin to develop these symptoms should be promptly evaluated for systemic lymphoma.¹

First, Blauvelt and colleagues presented findings from the ongoing LIBERTY AD PED-OLE open-label extension study, including 294 adolescents with moderate to severe AD who participated in previous dupilumab trials. Patients received a maintenance dose of 300 mg dupilumab every 4 weeks, which was increased to a weight-based every-other-week regimen if there was inadequate clinical response to every-4-week dosing. They found that 81.2% of patients achieved an Eczema Area and Severity Index (EASI-75) response at week 52 with every-4-week dosing, and 51.9% of patients at week 48 after switching to every-2-week doing. These results indicate that some adolescents may be able to maintain clinical efficacy with monthly dosing, while others may require every-2-week dosing. Of note, no new safety signals emerged during the study and most adverse events were mild to moderate.

Two more studies were published showing real-world effectiveness and safety of dupilumab. Eichenfield and colleagues performed a retrospective, observational study of the effectiveness of dupilumab after 4 months of treatment using data from national electronic medical records in adults with moderate-to-severe AD. They found that most patients achieved at least a one-grade (81.8%) or two-grade (62.8%) improvement of their Investigator's Global Assessment (IGA) scores, with 42.8% achieving IGA scores of 0/1 (clear/minimal). There were also significant improvements in itch and lesional extent. The results were remarkably similar to those observed in the phase 3 clinical trial program of dupilumab in adults with moderate-to-severe AD.

Bagel and colleagues published baseline characteristics of patients enrolled in the ongoing PROSE longitudinal real-world registry of dupilumab use in adults with moderate-to-severe AD. Almost half of the patients (49.5%) previously received systemic medications, including 41.0% with systemic corticosteroids, 16.8% with nonsteroidal systemic therapies, such as cyclosporine and methotrexate, and 10.2% with phototherapy. This result indicates that many medical professionals are not using dupilumab as a first-line systemic therapy, despite its established record on safety and efficacy. It appears that many clinicians prefer a short-term treatment regimen, such as systemic corticosteroids, prior to initiating long-term treatment with dupilumab. However, short-term treatment approaches are not ideal for this chronic and often lifelong disease. It is important that clinicians develop appropriate long-term treatment approaches for atopic dermatitis in general, regardless of any specific therapy.

On a different research note, my research group just published the results of a longitudinal dermatology practice–based study of depressive symptoms in 695 adults with AD over time.¹ We found that approximately half of the patients experienced fluctuating severity of depressive symptoms, and 45.65% experienced persistent severity of depression. Severity of AD lesions and itch were the strongest predictors of more severe symptoms of depression. Perhaps most fascinating about this research was that symptoms of depression improved dramatically in a very large subset of patients who experienced reduced AD severity with standard-of-care treatment. These results highlight the broader impacts of AD on mental health, which were recently recognized by the American Academy of Dermatology's guideline update on AD comorbidities.² Moreover, our study demonstrated that many of these mental health impacts were modifiable with optimized AD therapy.

First, Blauvelt and colleagues presented findings from the ongoing LIBERTY AD PED-OLE open-label extension study, including 294 adolescents with moderate to severe AD who participated in previous dupilumab trials. Patients received a maintenance dose of 300 mg dupilumab every 4 weeks, which was increased to a weight-based every-other-week regimen if there was inadequate clinical response to every-4-week dosing. They found that 81.2% of patients achieved an Eczema Area and Severity Index (EASI-75) response at week 52 with every-4-week dosing, and 51.9% of patients at week 48 after switching to every-2-week doing. These results indicate that some adolescents may be able to maintain clinical efficacy with monthly dosing, while others may require every-2-week dosing. Of note, no new safety signals emerged during the study and most adverse events were mild to moderate.

Two more studies were published showing real-world effectiveness and safety of dupilumab. Eichenfield and colleagues performed a retrospective, observational study of the effectiveness of dupilumab after 4 months of treatment using data from national electronic medical records in adults with moderate-to-severe AD. They found that most patients achieved at least a one-grade (81.8%) or two-grade (62.8%) improvement of their Investigator's Global Assessment (IGA) scores, with 42.8% achieving IGA scores of 0/1 (clear/minimal). There were also significant improvements in itch and lesional extent. The results were remarkably similar to those observed in the phase 3 clinical trial program of dupilumab in adults with moderate-to-severe AD.

Bagel and colleagues published baseline characteristics of patients enrolled in the ongoing PROSE longitudinal real-world registry of dupilumab use in adults with moderate-to-severe AD. Almost half of the patients (49.5%) previously received systemic medications, including 41.0% with systemic corticosteroids, 16.8% with nonsteroidal systemic therapies, such as cyclosporine and methotrexate, and 10.2% with phototherapy. This result indicates that many medical professionals are not using dupilumab as a first-line systemic therapy, despite its established record on safety and efficacy. It appears that many clinicians prefer a short-term treatment regimen, such as systemic corticosteroids, prior to initiating long-term treatment with dupilumab. However, short-term treatment approaches are not ideal for this chronic and often lifelong disease.
