The Food and Drug Administration has approved marketing for a device that will help diagnose autism spectrum disorder (ASD) in children between the ages of 18 months and 5 years old who exhibit potential symptoms.

Cognoa ASD Diagnosis Aid is a machine learning–based software program that receives information from parents or caregivers, video analysts, and health care providers to assist physicians in evaluating whether a child is at risk of having autism.

Autism is a developmental disorder that can cause social, communication, and behavioral challenges, according to the Centers for Disease Control and Prevention. The disorder affects about 1 in 54 children. The disorder is difficult to diagnose because there isn’t a medical test to diagnose the it. Instead, physicians have to look at a child’s developmental history and behavior to make a diagnosis.

Many children are not diagnosed with ASD until later in childhood, which in some cases delays treatment and early intervention. ASD may be detected as early as 18 months, but the average age of diagnosis for ASD is 4.3 years, according to the FDA.

“[ASD] can delay a child’s physical, cognitive, and social development, including motor skill development, learning, communication, and interacting with others. The earlier ASD can be diagnosed, the more quickly intervention strategies and appropriate therapies can begin,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, said in a statement. “Today’s marketing authorization provides a new tool for helping diagnose children with ASD.”

The safety and efficacy of the Cognoa ASD Diagnosis Aid was assessed in a study of 425 patients between the ages of 18 months and 5 years old. For the study, researchers compared the diagnostic assessments made by the device to those made by a panel of clinical experts who used the current standard ASD diagnostic process. The device diagnosed 32% of the children with either a “Positive for ASD” or a “Negative for ASD” result. Researchers found that the device matched the panel’s conclusions for 81% of the patients who received a positive diagnosis. For those who received a negative diagnosis, the device matched the panel’s conclusions for 98% of the patients. In addition, the device made an accurate ASD determination in 98.4% of patients with the condition and in 78.9% of patients without the condition.

Cognoa ASD Diagnosis Aid has three main components. One component includes a mobile app for caregivers to answer questions about the child’s behavioral problems and to upload videos of the child. The next component is a video analysis portal for specialists to view and analyze uploaded videos of patients. Another component is a portal for health care providers that allows them to enter answers to preloaded questions about behavior problems, track the information provided by parents, and review a report of the results.

After the machine learning–based device processes the information provided by parents and health care providers, it reports either a positive or a negative diagnosis. If there is insufficient information to make either a positive or a negative diagnosis, the ASD Diagnostic AID will report that no result can be generated.

Some of the risks associated with this device include misdiagnosis and delayed diagnosis of ASD because of a false-positive or false-negative result, or when no result is generated. Researchers said a false-positive result occurred in 15 out of 303 study subjects without ASD and a false-negative result occurred in 1 out of 122 study subjects with ASD.

The FDA emphasized that the device is indicated to aid physicians in the process of diagnosing ASD in children. This means it shouldn’t be treated as a standalone diagnostic device, but as an adjunct to the diagnostic process.

Botulinum toxin is said to be the most lethal substance known. Inhaling just 1-3 nanograms of toxin per kilogram of body mass constitutes a lethal dose. 

Now the Centers for Disease Control and Prevention has published the first comprehensive guide to the diagnosis and treatment of botulism. The CDC has been working on these guidelines since 2015, initially establishing a technical development group and steering committee to prioritize topics for review and make recommendations. Since then, the agency published 15 systematic reviews in  Clinical Infectious Diseases early in 2018. The reviews addressed the recognition of botulism clinically, treatment with botulinum antitoxin, and complications from that treatment. They also looked at the epidemiology of botulism outbreaks and botulism in the special populations of vulnerable pediatric and pregnant patients.

In 2016, the CDC held two extended forums and convened a workshop with 72 experts. In addition to the more standard topics of diagnosis and treatment, attention was given to crisis standards of care, caring for multiple patients at once, and ethical considerations in management.

Amesh Adalja, MD, senior scholar, Johns Hopkins Center for Health Security, Baltimore, said in an interview that the new guidance “was really specific [and] was meant to address the gap in guidance for mass casualty settings.”

While clinicians are used to focusing on an individual patient, in times of crises, with multiple patients from a food-borne outbreak or a bioterrorism attack, the focus must shift to the population rather than the individual. The workshop explored issues of triaging, adding beds, and caring for patients when a hospital is overwhelmed with an acute influx of severely ill patients.

Such a mass casualty event is similar to the stress encountered this past year with COVID-19 patients swamping the hospitals, which had too little oxygen, too few ventilators, and too few staff members to care for the sudden influx of critically ill patients.
 

Diagnosis

Leslie Edwards, MHS, BSN, a CDC epidemiologist and botulism expert, said that “botulism is rare and [so] could be difficult to diagnose.” The CDC “wanted to highlight some of those key clinical factors” to speed recognition.

Hospitals and health officials are being urged to develop crisis protocols as part of emergency preparedness plans. And clinicians should be able to recognize four major syndromes: botulism from food, wounds, and inhalation, as well as iatrogenic botulism (from exposure via injection of the neurotoxin).

Botulism has a characteristic and unusual pattern of symptoms, which begin with cranial nerve palsies. Then there is typically a descending, symmetric flaccid paralysis. Symptoms might progress to respiratory failure and death. Other critical clues that implicate botulism include a lack of sensory deficits and the absence of pain.

Symptoms are most likely to be mistaken for myasthenia gravis or Guillain-Barré syndrome, but the latter has an ascending paralysis. Cranial nerve involvement can present as blurred vision, ptosis (drooping lid), diplopia (double vision), ophthalmoplegia (weak eye muscles), or difficulty with speech and swallowing. Shortness of breath and abdominal discomfort can also occur. Respiratory failure may occur from weakness or paralysis of cranial nerves. Cranial nerve signs and symptoms in the absence of fever, along with a descending paralysis, should strongly suggest the diagnosis.

With food-borne botulism, vomiting occurs in half the patients. Improperly sterilized home-canned food is the major risk factor. While the toxin is rapidly destroyed by heat, the bacterial spores are not. Wound botulism is most commonly associated with the injection of drugs, particularly black tar heroin.

Dr. Edwards stressed that “time is of the essence when it comes to botulism diagnostics and treating. Timely administration of the botulism antitoxin early in the course of illness can arrest the progression of paralysis and possibly avert the need for intubation or ventilation.”

It’s essential to note that botulism is an urgent diagnosis that has to be made on clinical grounds. Lab assays for botulinum neurotoxins take too long and are only conducted in public health laboratories. The decision to use antitoxin must not be delayed to wait for confirmation.

Clinicians should immediately contact the local or state health department’s emergency on-call team if botulism is suspected. They will arrange for expert consultation.
 

Treatment

Botulinum antitoxin is the only specific therapy for this infection. If given early – preferably within 24-48 hours of symptom onset – it can stop the progression of paralysis. But antitoxin will not reverse existing paralysis. If paralysis is still progressing outside of that 24- to 48-hour window, the antitoxin should still provide benefit. The antitoxin is available only through state health departments and a request to the CDC.

Botulism antitoxin is made from horse serum and therefore may cause a variety of allergic reactions. The risk for anaphylaxis is less than 2%, far lower than the mortality from untreated botulism.

While these guidelines have an important focus on triaging and treating mass casualties from botulism, it’s important to note that food-borne outbreaks and prevention issues are covered elsewhere on the CDC site.

Dr. Edwards has disclosed no relevant financial relationships. Dr. Adalja is a consultant for Emergent BioSolutions, which makes the heptavalent botulism antitoxin.

Dr. Stone is an infectious disease specialist and author of “Resilience: One Family’s Story of Hope and Triumph Over Evil” and of “Conducting Clinical Research,” the essential guide to the topic. You can find her at drjudystone.com or on Twitter @drjudystone.

The U.S. Food and Drug Administration has approved a once-daily oral medication, which is a combination of olanzapine and samidorphan (Lybalvi, Alkermes), for the treatment of schizophrenia and bipolar I disorder.

The drug is approved for the treatment of adults with schizophrenia and for adults with bipolar I disorder as a maintenance monotherapy or to treat acute manic or mixed episodes, as either monotherapy or an adjunct to lithium or valproate.

An atypical antipsychotic, the drug is a combination of olanzapine, an established antipsychotic medication, and samidorphan, a new chemical entity.

“Schizophrenia and bipolar I disorder are complex, chronic diseases, and there remains a persistent need for new medications with proven efficacy and safety. Olanzapine, a highly efficacious atypical antipsychotic, is associated with significant side effects, including weight gain that may impact patients’ treatment experiences and limit its use. With the efficacy of olanzapine and evidence of less weight gain in patients with schizophrenia, Lybalvi brings a welcome new addition to our medication arsenal,” René S. Kahn, MD, PhD, Esther and Joseph Klingenstein professor & chair, department of psychiatry and Behavioral Health System at the Icahn School of Medicine at Mount Sinai, New York, said in a company press release.

In a clinical development program, the drug demonstrated antipsychotic efficacy, safety, and tolerability, including significantly less weight gain than olanzapine in patients with schizophrenia in the ENLIGHTEN-2 study.

The FDA approved Lybalvi under the 505(b)(2) regulatory pathway based on data from 27 clinical studies, including 18 studies evaluating Lybalvi and nine studies evaluating samidorphan alone and the FDA’s findings of the safety and effectiveness of olanzapine in the treatment of bipolar I disorder and schizophrenia. Data suggest that olanzapine-associated weight gain is disease independent, the company reports.

“People living with schizophrenia or bipolar I disorder must evaluate both efficacy and tolerability when making treatment decisions,” Paul Gionfriddo, president and CEO of Mental Health America, said in the same company press release. “We are grateful that companies like Alkermes are driven to continue developing new treatment options in psychiatry that seek to address unmet needs of our community, and we applaud the FDA for considering the experiences of individuals living with these conditions.” 

Alkermes expects to make Lybalvi available for patients in the fourth quarter of 2021.

The first drug to target KRAS mutations in non–small cell lung cancer (NSCLC) has been approved by the Food and Drug Administration.

KRAS mutations are the most common mutations to occur in NSCLC tumors, accounting for about 25% of them, but for a long time they appeared to be resistant to drug therapy.  

The new drug, sotorasib (Lumakras), specifically targets the KRAS G12C mutation, which accounts for about 13% of NSCLC mutations.

It is considered to be something of a breakthrough in cancer research. When clinical data on the new drug (from 126 patients) were presented last year at the World Conference on Lung Cancer, lung cancer experts greeted the results enthusiastically, as reported by Medscape Medical News at the time.

“This is a historic milestone in lung cancer therapy. After four decades of scientific efforts in targeting KRAS, sotorasib has potential to be the first targeted treatment option for this patient population with a high unmet need,” Bob T. Li, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, said at the time.

Now, in a press release from the manufacturer, Amgen, he said: “Sotorasib represents a major advancement in oncology and changes the treatment paradigm for patients with KRAS G12C-mutated non–small cell lung cancer.

“Patients with non–small cell lung cancer who have progressed beyond first-line treatment face a poor prognosis and have limited treatment options available to them. Sotorasib delivers a new option for these patients, and it is the first KRAS-targeted therapy to be approved after nearly four decades of research,” he added.
 

Details of clinical data

This is an accelerated approval based on response rate data.

The FDA notes that the clinical data come from a study of 124 patients with locally advanced or metastatic KRAS G12C-mutated NSCLC with disease progression after receiving an immune checkpoint inhibitor and/or platinum-based chemotherapy.

The major outcome measured was overall response rate (ORR), which was 36%. Of the patients who responded, 58% had a duration of response of 6 months or longer.

Sotorasib was approved at a dose of 960 mg, and this dose was based on available clinical data as well as pharmacokinetic and pharmacodynamic modeling, the FDA noted. As part of the evaluation for this accelerated approval, the agency is requiring a postmarketing trial to investigate whether a lower dose will have a similar clinical effect.

The most common side effects include diarrhea, musculoskeletal pain, nausea, fatigue, liver damage, and cough. Sotorasib should not be used if patients develop symptoms of interstitial lung disease, and should be permanently discontinued if interstitial lung disease is confirmed.

Patients on sotorasib should have liver function tests prior to starting and while taking the drug; if liver damage develops, the drug should be stopped or the dose reduced. Patients should avoid taking acid-reducing agents, drugs that induce or are substrates for certain enzymes in the liver, and drugs that are substrates of P-glycoprotein (P-gp).
 

Companion diagnostic tests also approved

Along with the new drug, the FDA approved two companion diagnostic tests – the QIAGEN therascreen KRAS RGQ PCR kit (approval granted to QIAGEN GmbH) for analyzing tumor tissue and the Guardant360 CDx (approval granted to Guardant Health) for analyzing plasma specimens to determine if the KRAS G12C mutation is present. The agency notes that if the plasma test comes back negative, the patient’s tumor tissue should be tested.

The first drug to target KRAS mutations in non–small cell lung cancer (NSCLC) has been approved by the Food and Drug Administration.

KRAS mutations are the most common mutations to occur in NSCLC tumors, accounting for about 25% of them, but for a long time they appeared to be resistant to drug therapy.  

The new drug, sotorasib (Lumakras), specifically targets the KRAS G12C mutation, which accounts for about 13% of NSCLC mutations.

It is considered to be something of a breakthrough in cancer research. When clinical data on the new drug (from 126 patients) were presented last year at the World Conference on Lung Cancer, lung cancer experts greeted the results enthusiastically, as reported by Medscape Medical News at the time.

“This is a historic milestone in lung cancer therapy. After four decades of scientific efforts in targeting KRAS, sotorasib has potential to be the first targeted treatment option for this patient population with a high unmet need,” Bob T. Li, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, said at the time.

Now, in a press release from the manufacturer, Amgen, he said: “Sotorasib represents a major advancement in oncology and changes the treatment paradigm for patients with KRAS G12C-mutated non–small cell lung cancer.

A Food and Drug Administration advisory panel has voted narrowly to recommend approval of the monoclonal antibody teplizumab (Tzield, Provention Bio) for the delay of type 1 diabetes in at-risk individuals.

The 10-7 vote of the FDA’s endocrinologic and metabolic drugs advisory committee on May 27 reflected a difficult decision-making process on the part of many members to weigh the benefits of a potential 2-year delay in the onset of type 1 diabetes against both observed and theoretical risks, as well as what most considered to be insufficient data.

Regardless of their vote, nearly all panel members advised the FDA that the company should be required to conduct at least one additional larger long-term efficacy and safety trial to satisfy what they felt were major gaps in the data. Some advised that use of the drug be restricted to a very narrow group of recipients until efficacy and safety can be better established.

If approved, teplizumab, which interferes with T cell–mediated autoimmune destruction of pancreatic beta cells, would be the first disease-modifying therapy for impeding progression of type 1 diabetes. The proposed indication is for individuals who have two or more type 1 diabetes-associated autoantibodies and subclinical dysglycemia.

That “stage 2” or “at-risk” condition is associated with a nearly 100% lifetime risk of progression to clinical (“stage 3”) type 1 diabetes and a 75% risk of developing the disease within 5 years. As of now, most such individuals are first-degree relatives of people with type 1 diabetes identified through TrialNet.
 

What’s the evidence to support approval so far?

In 2019, a pivotal phase 2 randomized, placebo-controlled TN-10 trial involving 76 at-risk children and adults ages 8 years and older showed that a single 14-day treatment of daily intravenous infusions of teplizumab in 44 patients resulted in a significant median 2-year delay to onset of clinical type 1 diabetes, compared with 32 who received placebo. Further follow-up data continue to show that fewer patients who received teplizumab have progressed to clinical type 1 diabetes.

While most advisory panelists agreed that the TN-10 study demonstrated efficacy, several also said that the sample size was insufficient and at least one additional randomized trial should be conducted to replicate the findings.

Although the FDA typically requires companies to demonstrate a drug’s effectiveness with at least two separate clinical trials, the agency allows companies to substitute other forms of data for a second randomized clinical trial, such as study results for the drug in a closely related condition, mechanistic data, or knowledge of other drugs from the same class.

In this case, Provention’s submission included as “confirmatory” evidence a meta-analysis of data from five earlier randomized trials (three placebo controlled, two open label) of a total 942 individuals with newly diagnosed type 1 diabetes (“stage 3”) who received either one or two 14-day teplizumab courses (n = 729) or placebo. These showed consistent preservation of C-peptide, a surrogate marker of beta-cell function, along with lower mean insulin use.

Several panel members expressed dissatisfaction with those confirmatory data, noting the patient population was different from those for which the company is currently seeking the indication, and that C-peptide is an inadequate endpoint for demonstrating efficacy.
 

Safety: Adverse events mostly transient, but unanswered questions

Adverse events reported in at least 10% of teplizumab recipients included lymphopenia (76.8% vs. 9.4% placebo; relative risk, 8.2), leukopenia (82.1% vs. 24.1%; RR, 3.4), and rash (44.5% vs. 9.0%; RR, 4.9).

“Most adverse events related to teplizumab were mechanism-based, predictable, transient, and manageable,” Chief Medical Officer of Provention Bio, Eleanor Ramos, MD, said.

Among other safety issues that concerned the panel, diabetic ketoacidosis (DKA) was seen in 2.3% of 773 teplizumab recipients with new-onset type 1 diabetes versus just 1% among the 245 controls, a significant, nearly sixfold increase. No DKA occurred in the TN-10 trial. No clear explanation was offered for the imbalance in the meta-analysis.

Cytokine release syndrome occurred in 0.6% of patients who received teplizumab versus no controls, and infections in 3.4% versus 2.0%, respectively.

Approximately 10% of patients were not able to complete the treatment course because of protocol-directed withdrawal criteria, which included elevations in bilirubin or liver enzymes, or drops in platelet count, neutrophils, or hemoglobin, FDA reviewer Lauren Wood Heickman, MD, noted.

There was only one malignancy, a melanoma in a patient with a preexisting lesion, but malignancy is a theoretical concern with long-term immunosuppression, Dr. Heickman said.

Despite the concerns about the data, panel members expressed unanimous appreciation for the 18 people who spoke during public comments attesting to the lifelong burdens involved in living with type 1 diabetes who urged the FDA to approve teplizumab.

Many of them noted that even a 2-year reprieve from the burden of constant attention to managing blood glucose can make a major difference in the life of a young person. The speakers included physicians, parents of children with type 1 diabetes, adults who have the condition themselves and who worry about their children getting it, and researchers in the field.
 

Panel members describe ‘struggle’ with vote decision

Panel member Michael Blaha, MD, of Johns Hopkins University, Baltimore, voted in favor of teplizumab approval. However, he said, “I was very conflicted on this one and my ‘yes’ is very qualified. In my opinion the risk-benefit is very narrow, and I would only approve this drug for the exact indication of the trial. ... Patients who don’t fit the criteria could hopefully be enrolled in a second confirmatory trial.”

He also advised an extensive Risk Evaluation and Mitigation Strategies program to look for both short- and long-term adverse effects.

“My overall take on this is that I do think it’s a promising paradigm-shifting therapy that really needs to move forward, at least scientifically. I’m excited about it, but I have a lot of skepticism about the entire body of data to make any more than the most narrow of approval,” Dr. Blaha said.  

Susan S. Ellenberg, PhD, professor of biostatistics, medical ethics, and health policy at the University of Pennsylvania, Philadelphia, voted yes but also with difficulty.

“I really struggled with it. ... I was pushed by the very encouraging results of what is admittedly a very small study and something I can’t feel is completely definitive. But I would not like to deny the kind of people that we heard from today the opportunity to weigh their own risks and benefits to try this. And I would certainly agree that a very, very rigorous postmarketing program, preferably including another controlled trial, should be carried out.”

But David M. Nathan, MD, director of the Diabetes Center and Clinical Research Center, Massachusetts General Hospital, Boston, voted no.

“I struggled with this vote, tremendously, having listened carefully to the patients with type 1 diabetes ... but that said, having done clinical research for 40 years in type 1 diabetes, I think we need more data, both in terms of efficacy and of safety. I would hate a number of years down the road to figure out that we actually caused more harm than good, especially keeping in mind that the treatment of type 1 diabetes is evolving rapidly.”

A different perspective came from Mara L. Becker, MD, vice chair of the department of pediatric rheumatology at Duke University, Durham, N.C. She voted yes, pointing out that she’s accustomed to prescribing biologics for chronic conditions in children.

“I was unconflicted in my vote, which was yes. I thought the data ... were convincing and the need is great. I would support a label for children [aged 8 years] and older with at least stage 2 disease ... and I would require postmarketing safety surveillance to understand what the long-term side effects could be, but I would still be in favor of it.”

FDA advisory panel committee members are vetted for conflicts of interest and waivers granted for participation if necessary; none were granted for this meeting.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).

The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.

The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.

The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.

In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.

Impairment of cognitive function is a major burden for people with schizophrenia, and no pharmacologic treatments are currently approved for CIAS.

“Cognition is a fundamental aspect of everyday life, including problem solving, memory, and attention, which is why finding solutions for cognitive impairment is a key area of Boehringer Ingelheim mental health research,” Vikas Mohan Sharma, MS, with Boehringer Ingelheim, said in a news release.

“This breakthrough therapy designation further highlights the urgent need for novel treatments for people living with schizophrenia. By combining traditional treatment approaches with new and innovative technologies, we are developing targeted therapies that will help to ease the burden of mental health conditions and enable people living with these conditions to create more meaningful connections to their lives, loved ones, and society,” said Mr. Sharma.

The CONNEX clinical trial program is composed of three clinical trials – CONNEX-1, CONNEX-2, and CONNEX-3. All are phase 3 randomized, double-blind, placebo-controlled parallel group trials that will examine the efficacy and safety of BI 425809 taken once daily over a 26-week period for patients with schizophrenia.

The primary outcome measure is change from baseline in overall composite T-score of the Measurement and Treatment Research to Improve Cognition in Schizophrenia consensus cognitive battery.

The CONNEX trial program will use VeraSci’s Pathway electronic clinical outcome assessment platform, including VeraSci’s Virtual Reality Functional Capacity Assessment Tool (VRFCAT), which simulates key instrumental activities of daily living in a realistic interactive virtual environment, VeraSci explains in a news release announcing the partnership with Boehringer Ingelheim.

The VRFCAT is sensitive to functional capacity deficits and has been accepted into the FDA’s Clinical Outcome Assessment Qualification Program.

The CONNEX trials will also utilize speech biomarker technology from Aural Analytics, which will provide a “richer picture of trial participants’ cognition alongside more conventional clinical outcome measures,” Boehringer Ingelheim says.

“Several of the symptoms of schizophrenia are generated by cognitive and emotional processes that can be identified through disruptions in the outward flow of speech. Using innovative speech analytics may help to objectively assess the downstream consequences of these disruptions,” said Daniel Jones, Aural Analytics co-founder and CEO.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).

The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.

The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.

The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.

In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.

Impairment of cognitive function is a major burden for people with schizophrenia, and no pharmacologic treatments are currently approved for CIAS.

The risk for serious liver injury with obeticholic acid (Ocaliva, Intercept Pharmaceuticals) has prompted the U.S. Food and Drug Administration to restrict its use in patients with primary biliary cholangitis (PBC) and advanced cirrhosis.  

The agency has added a new contraindication to the obeticholic acid prescribing information and patient medication guide stating that the drug should not be used in patients with PBC and advanced cirrhosis. 

The boxed warning on the label has also been revised to include this information.

For patients with PBC who do not have advanced cirrhosis, the FDA believes the benefits of Ocaliva outweigh the risks, based on the original clinical trials.

Five years ago, the FDA granted accelerated approval to obeticholic acid in combination with ursodeoxycholic acid (UDCA) in adults who fail to respond adequately to UDCA, or as a monotherapy in adults who cannot tolerate UDCA.  

Since then, the FDA has identified 25 cases of serious liver injury leading to liver decompensation or liver failure in patients with PBC and cirrhosis who were taking obeticholic acid at recommended doses.

According to the FDA, 18 of the cases happened in patients with PBC and compensated cirrhosis who experienced liver injury that led to decompensation. Ten of these patients had evidence or suspicion of portal hypertension at baseline; in the other eight patients, it was unclear whether portal hypertension was present.

PBC was not expected to progress rapidly in these patients, yet they experienced accelerated clinical deterioration within months of starting obeticholic acid, the FDA said.

The median time to liver decompensation after initiating treatment was 4 months (range, 2 weeks to 10 months). Four patients with PBC and compensated cirrhosis needed a liver transplant within 1.3 years after starting obeticholic acid, and one patient died from liver failure.

The other seven cases of serious liver injury occurred in patients with PBC and decompensated cirrhosis, two of whom died. 

Although there was a temporal relationship between starting obeticholic acid and liver injury, it is difficult to distinguish a drug-induced effect from disease progression in the patients with advanced baseline liver disease, the FDA cautioned.

The median time to a new decompensation event after starting the drug was 2.5 months (range, 10 days to 8 months).

Before starting obeticholic acid, clinicians should determine whether a patient with PBC has advanced cirrhosis as the drug is now contraindicated in these patients, the FDA said.

During obeticholic acid treatment, patients should be routinely monitored for progression of PBC with laboratory and clinical assessments to determine whether the drug needs to be discontinued.

The medication should be permanently discontinued in patients with cirrhosis who progress to advanced cirrhosis.

Patients should also be monitored for clinically significant liver-related adverse reactions that may manifest as development of acute-on-chronic liver disease with nausea, vomiting, diarrhea, jaundice, scleral icterus, and/or dark urine.

Obeticholic acid should be stopped permanently in any patient who develops these symptoms, the FDA advised.

Health care professionals are encouraged to report adverse events or side effects related to the use of obeticholic acid to MedWatch, FDA’s adverse event reporting site.

The benefits of COVID-19 vaccination “enormously outweigh” the rare possible risk for heart-related complications, including myocarditis, the American Heart Association/American Stroke Association (ASA) says in new statement.

The message follows a Centers for Disease Control and Prevention report that the agency is monitoring the Vaccine Adverse Events Reporting System (VAERS) and the Vaccine Safety Datalink (VSD) for cases of myocarditis that have been associated with the mRNA vaccines against SARS-CoV-2 from Pfizer and Moderna.

The “relatively few” reported cases myocarditis in adolescents or young adults have involved males more often than females, more often followed the second dose rather than the first, and were usually seen in the 4 days after vaccination, the CDC’s COVID-19 Vaccine Safety Technical Work Group (VaST) found.

“Most cases appear to be mild, and follow-up of cases is ongoing,” the CDC says. “Within CDC safety monitoring systems, rates of myocarditis reports in the window following COVID-19 vaccination have not differed from expected baseline rates.”

In their statement, the AHA/ASA “strongly urge” all adults and children 12 years and older to receive a COVID-19 vaccine as soon as possible.

“The evidence continues to indicate that the COVID-19 vaccines are nearly 100% effective at preventing death and hospitalization due to COVID-19 infection,” the groups say.

Although the investigation of cases of myocarditis related to COVID-19 vaccination is ongoing, the AHA/ASA notes that myocarditis is typically the result of an actual viral infection, “and it is yet to be determined if these cases have any correlation to receiving a COVID-19 vaccine.”

“We’ve lost hundreds of children, and there have been thousands who have been hospitalized, thousands who developed an inflammatory syndrome, and one of the pieces of that can be myocarditis,” Richard Besser, MD, president and CEO of the Robert Wood Johnson Foundation (RWJF), said today on ABC’s Good Morning America.

Still, “from my perspective, the risk of COVID is so much greater than any theoretical risk from the vaccine,” said Dr. Besser, former acting director of the CDC.

The symptoms that can occur after COVID-19 vaccination include tiredness, headache, muscle pain, chills, fever, and nausea, reminds the AHA/ASA statement. Such symptoms would “typically appear within 24-48 hours and usually pass within 36-48 hours after receiving the vaccine.”

All health care providers should be aware of the “very rare” adverse events that could be related to a COVID-19 vaccine, including myocarditis, blood clots, low platelets, and symptoms of severe inflammation, it says.

“Health care professionals should strongly consider inquiring about the timing of any recent COVID vaccination among patients presenting with these conditions, as needed, in order to provide appropriate treatment quickly,” the statement advises.

A rare, life-threatening anemia now has a new treatment option. The Food and Drug Administration announced the approval of pegcetacoplan (Empaveli) injection to treat adults with paroxysmal nocturnal hemoglobinuria (PNH). Pegcetacoplan is the first PNH treatment that binds to complement protein C3, according to the FDA announcement. Complement protein C3 is a key component of host immunity and defense.

Special concern

Because of the risk of severe side effects, the drug is available only through a restricted program under a risk evaluation and mitigation strategy (REMS). Serious infections can occur in patients taking pegcetacoplan that can become life-threatening or fatal if not treated early. According to the FDA, REMS are designed to reinforce medication use behaviors and actions that support the safe use of that medication, and only a few drugs require a REMS.

The most common other side effects are injection site reactions, diarrhea, abdominal pain, and fatigue.

Pegcetacoplan was approved based upon a study of 80 patients with PNH and anemia who had been taking eculizumab, a previously approved treatment. During 16 weeks of treatment, patients in the pegcetacoplan group had an average increase in their hemoglobin of 2.4 g/dL, while patients in the eculizumab group had an average decrease in their hemoglobin of 1.5 g/dL.
 

About the disease

PNH is caused by gene mutations that affect red blood cells, causing them to be defective and susceptible to destruction by a patient’s own immune system. Red blood cells in people with these mutations are defective and can be destroyed by the immune system, causing anemia.

Other symptoms include blood clots and destruction of bone marrow. The disease affects 1-1.5 people per million, with diagnosis typically occurring around ages 35-40, and a median survival of only 10 years after diagnosis, according to the FDA.

The Food and Drug Administration is launching a process to prepare an environmental impact statement (EIS) regarding the use oxybenzone and octinoxate in over-the-counter sunscreen products.

According to the “Intent to Prepare an Environmental Impact Statement for Certain Sunscreen Drug Products for Over-The-Counter Use,” which was published in the Federal Register on May 13, 2021, the FDA will prepare an EIS “when data or information in an environmental assessment or otherwise available to the Agency leads to a finding that the proposed agency action may significantly affect the quality of the human environment.” The first step in this effort involves a “public scoping process” to evaluate any potential environmental impacts associated with the use of oxybenzone and octinoxate in sunscreens so that an EIS, if required, “can be completed prior to issuance of a final sunscreen order addressing sunscreens containing these ingredients.”

The American Academy of Dermatology Association weighed in on the FDA’s announcement, noting that it “appreciates the efforts of the agency to thoroughly examine all relevant science before issuing a final sunscreen order on these ingredients,” according to a statement released by the AADA on May 13, 2021.

The statement added: “Skin cancer is the most common cancer in the U.S., and unprotected exposure to the sun’s harmful ultraviolet rays is a major risk factor. The AADA continues to focus on encouraging members of the public to protect themselves by seeking shade, wearing protective clothing – including a lightweight and long-sleeved shirt, pants, a wide-brimmed hat and sunglasses – and applying a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin.”

According to the FDA document, a series of developments regarding oxybenzone and octinoxate prompted the agency to take this step, including comments the agency received in response to the 2019 proposed rule titled “Sunscreen Drug Products for Over-The-Counter Human Use,” which raised concern about the potential effects of the two ingredients on coral and/or coral reefs, as well as research efforts by the National Oceanic and Atmospheric Administration Coral Reef Conservation Programs on the potential impacts of sunscreen products that include oxybenzone and octinoxate on coral reefs and other aquatic systems. Hawaii’s 2018 state law prohibiting the sale, offer of sale, and distribution of sunscreens that contain oxybenzone and/or octinoxate also influenced the agency’s decision to further evaluate the topic.

“The purpose of the public scoping process is to determine relevant issues that will influence the scope of the environmental analysis, including potential alternatives and the extent to which those issues and impacts will be analyzed,” the FDA document states. “At this initial stage of the scoping process, we have identified the following four alternatives: FDA will conclude that the inclusion of oxybenzone and octinoxate in sunscreens marketed without an NDA [new drug application] is impermissible; FDA will conclude that the inclusion of oxybenzone and octinoxate in sunscreens marketed without an NDA is permissible; FDA will conclude that inclusion of oxybenzone in sunscreens marketed without an NDA is permissible but that the inclusion of octinoxate in sunscreens marketed without an NDA is impermissible; or FDA will conclude that inclusion of octinoxate in sunscreens marketed without an NDA is permissible but that the inclusion of oxybenzone in sunscreens marketed without an NDA is impermissible.”

Until June 14, the FDA is accepting comments from the public electronically via the Federal eRulemaking Portal at www.regulations.gov (search for Docket No. FDA-2021-N-0352) or by mail to: Dockets Management Staff (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, Md., 20852.

According to the “Intent to Prepare an Environmental Impact Statement for Certain Sunscreen Drug Products for Over-The-Counter Use,” which was published in the Federal Register on May 13, 2021, the FDA will prepare an EIS “when data or information in an environmental assessment or otherwise available to the Agency leads to a finding that the proposed agency action may significantly affect the quality of the human environment.” The first step in this effort involves a “public scoping process” to evaluate any potential environmental impacts associated with the use of oxybenzone and octinoxate in sunscreens so that an EIS, if required, “can be completed prior to issuance of a final sunscreen order addressing sunscreens containing these ingredients.”

The American Academy of Dermatology Association weighed in on the FDA’s announcement, noting that it “appreciates the efforts of the agency to thoroughly examine all relevant science before issuing a final sunscreen order on these ingredients,” according to a statement released by the AADA on May 13, 2021.

The statement added: “Skin cancer is the most common cancer in the U.S., and unprotected exposure to the sun’s harmful ultraviolet rays is a major risk factor. The AADA continues to focus on encouraging members of the public to protect themselves by seeking shade, wearing protective clothing – including a lightweight and long-sleeved shirt, pants, a wide-brimmed hat and sunglasses – and applying a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin.”

According to the FDA document, a series of developments regarding oxybenzone and octinoxate prompted the agency to take this step, including comments the agency received in response to the 2019 proposed rule titled “Sunscreen Drug Products for Over-The-Counter Human Use,” which raised concern about the potential effects of the two ingredients on coral and/or coral reefs, as well as research efforts by the National Oceanic and Atmospheric Administration Coral Reef Conservation Programs on the potential impacts of sunscreen products that include oxybenzone and octinoxate on coral reefs and other aquatic systems. Hawaii’s 2018 state law prohibiting the sale, offer of sale, and distribution of sunscreens that contain oxybenzone and/or octinoxate also influenced the agency’s decision to further evaluate the topic.

“The purpose of the public scoping process is to determine relevant issues that will influence the scope of the environmental analysis, including potential alternatives and the extent to which those issues and impacts will be analyzed,” the FDA document states. “At this initial stage of the scoping process, we have identified the following four alternatives: FDA will conclude that the inclusion of oxybenzone and octinoxate in sunscreens marketed without an NDA [new drug application] is impermissible; FDA will conclude that the inclusion of oxybenzone and octinoxate in sunscreens marketed without an NDA is permissible; FDA will conclude that inclusion of oxybenzone in sunscreens marketed without an NDA is permissible but that the inclusion of octinoxate in sunscreens marketed without an NDA is impermissible; or FDA will conclude that inclusion of octinoxate in sunscreens marketed without an NDA is permissible but that the inclusion of oxybenzone in sunscreens marketed without an NDA is impermissible.”

Until June 14, the FDA is accepting comments from the public electronically via the Federal eRulemaking Portal at www.regulations.gov (search for Docket No. FDA-2021-N-0352) or by mail to: Dockets Management Staff (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, Md., 20852. Refer to Docket No. FDA-2021-N-0352.
