Results from the latest survey by the National Comprehensive Cancer Network (NCCN) showed that numerous critical systemic anticancer therapies, primarily generic drugs, are currently in shortage.

Nearly 90% of the 28 NCCN member centers who responded to the survey, conducted between May 28 and June 11, said they were experiencing a shortage of at least one drug.

“Many drugs that are currently in shortage form the backbones of effective multiagent regimens across both curative and palliative treatment settings,” NCCN’s CEO Crystal S. Denlinger, MD, said in an interview.

The good news is that carboplatin and cisplatin shortages have fallen dramatically since 2023. At the peak of the shortage in 2023, 93% of centers surveyed reported experiencing a shortage of carboplatin and 70% were experiencing a shortage of cisplatin, whereas in 2024, only 11% reported a carboplatin shortage and 7% reported a cisplatin shortage.

“Thankfully, the shortages for carboplatin and cisplatin are mostly resolved at this time,” Dr. Denlinger said.

However, all three NCCN surveys conducted in the past year, including the most recent one, have found shortages of various chemotherapies and supportive care medications, which suggests this is an ongoing issue affecting a significant spectrum of generic drugs.

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”

TOPLINE:

People with obesity who exercise while taking glucagon-like peptide 1 receptor agonists (GLP-1 RAs; liraglutide) showed increased weight loss and preserved bone health, according to a study published in JAMA Network Open.

METHODOLOGY:

• Patients were placed on an initial diet that consisted of no more than 800 calories per day for 8 weeks. Those who lost at least 5% of their starting weight were then placed into a 1-year program.
• Participants included 195 adults aged between 18 and 65 years with obesity and no diabetes, 64% of whom were women.
• They were split into four groups of interventions: Exercise only (48 patients), liraglutide only (49 patients), a combination of both (49 participants), and placebo (49 participants), for a 1-year period.
• Patients received liraglutide or volume-matched placebo as daily injections starting at 0.6 mg/d with a weekly increase until 3 mg/d was reached; exercise entailed 30-minute sessions for 4 days a week.
• Researchers studied bone health at each patient’s hip, spine, and forearm after they lost weight, by measuring bone mineral density (BMD).

TAKEAWAY:

• The overall average change in weight loss over the course of 52 weeks was 7.03 kg in the placebo group, 11.19 kg in the exercise group, 13.74 kg in the liraglutide group, and 16.88 kg in the combination group.
• After the initial low-calorie diet-induced weight loss, the placebo group regained weight, the exercise and liraglutide groups maintained weight loss, and the combination group lost additional weight.
• BMD did not change in the combination group in comparison to the placebo group at the hip (mean change, −0.006 g/cm²; 95% CI, −0.017 to 0.004 g/cm²; P = .24) or spine (−0.010 g/cm²; 95% CI, −0.025 to 0.005 g/cm²; P = .20).
• BMD of the spine in the liraglutide group decreased in comparison to the exercise group (mean change, −0.016 g/cm²; 95% CI, −0.032 to −0.001 g/cm²; P = .04) and the placebo group, in addition to decreases in the hip.

IN PRACTICE:

“Our results show that the combination of exercise and GLP-1 RA was the most effective weight loss strategy while preserving bone health,” study authors wrote.

SOURCE:

The study was led by Simon Birk Kjær Jensen, PhD, of the Department of Biomedical Sciences and Faculty of Health and Medical Sciences at the University of Copenhagen in Denmark, and published on June 25 in JAMA Network Open.

LIMITATIONS:

The study only included adults aged between 18 and 65 years without other chronic diseases and may not apply to patients who are older or have diabetes. The study sample was diverse but was conducted in Denmark, with a population of generally similar ancestry.

DISCLOSURES:

One study author reported serving on advisory boards for AstraZeneca, Boehringer Ingelheim, Bayer, and Amgen, among others. Other authors reported various financial interests, including grants, personal fees, and salaries, from Amgen, Novo Nordisk, and Abbott Lab, among others.

LYON, FRANCE — The anti-obesity drug semaglutide is associated with significant reductions in the inflammatory marker high-sensitivity C-reactive protein (CRP), even in patients who do not lose substantial amounts of weight with the drug, according to data from the SELECT clinical trial.

The research, presented at the European Atherosclerosis Society 2024, involved over 17,600 patients with overweight or obesity and had established cardiovascular disease but not diabetes.

Those given semaglutide experienced a 38% reduction in high-sensitivity CRP levels compared with placebo regardless of baseline body mass index, statin use, cholesterol levels, and other measures.

“Weight loss was associated with greater high-sensitivity CRP reduction in both treatment groups,” said study presenter Jorge Plutzky, MD, director of Preventive Cardiology at Brigham and Women’s Hospital, Boston, but “with increased high-sensitivity CRP reductions in those receiving semaglutide.”

The drug also “significantly reduced high-sensitivity CRP early,” he said, “prior to major weight loss and in those who did not lose significant amounts of weight.” The reductions reached approximately 12% at 4 weeks and around 20% at 8 weeks, when the weight loss “was still quite modest,” at 2% and 3% of body weight, respectively. Even among patients who achieved weight loss of less than 2% body weight, semaglutide was associated with a reduction in high-sensitivity CRP levels.

In the SELECT trial, semaglutide also resulted in a consistent reduction of around 20% vs placebo in major adverse cardiovascular events such as cardiovascular mortality, nonfatal myocardial infarction, or nonfatal stroke.

But Naveed Sattar, MD, PhD, professor of cardiometabolic medicine at the University of Glasgow, Scotland, said in an interview that body weight “is probably the major driver” of CRP levels in the population, accounting for between 20% and 30% of the variation.

Dr. Sattar, who was not involved in the study, said that because drugs like semaglutide lower weight but also have anti-inflammatory effects, the question becomes: “Could the anti-inflammatory effects be part of the mechanisms by which these drugs affect the risk of major adverse cardiovascular events?”
 

Reducing Cardiovascular Events

The current analysis, however, cannot answer the question, he said. “All it tells us is about associations.”

“What we do know is semaglutide, predominantly by lowering weight, is lowering CRP levels and equally, we know that when you lose weight, you improve blood pressure, you improve lipids, and you reduce the risk of diabetes,” he said.

Dr. Sattar also took issue with the researchers’ conclusion that the high-sensitivity CRP reductions seen in SELECT occurred prior to major weight loss because the “pattern of CRP reduction and weight reduction is almost identical.”

Dr. Sattar also pointed out in a recent editorial that the drug appears to have a direct effect on blood vessels and the heart, which may lead to improvements in systemic inflammation. Consequently, he said, any assertion that semaglutide is genuinely anti-inflammatory is, at this stage, “speculation.”

Dr. Plutzky said that “systemic, chronic inflammation is implicated as a potential mechanism and therapeutic target in atherosclerosis and major adverse cardiovascular events, as well as obesity,” and high-sensitivity CRP levels are an “established biomarker of inflammation and have been shown to predict cardiovascular risk.”

However, the relationship between high-sensitivity CRP, responses to glucagon-like peptide 1 receptor agonists like semaglutide, and cardiovascular outcomes in obesity “remains incompletely understood,” said Dr. Plutzky.

The Food and Drug Administration (FDA) has issued new draft guidance that does not require additional switching studies for biosimilars seeking interchangeability. These studies were previously recommended to demonstrate that switching between the biosimilar and its reference product showed no greater risk than using the reference product alone.

“The recommendations in today’s draft guidance, when finalized, will provide clarity and transparency about the FDA’s thinking and align the review and approval process with existing and emerging science,” said Sarah Yim, MD, director of the FDA’s Office of Therapeutic Biologics and Biosimilars in a statement on June 20. “We have gained valuable experience reviewing both biosimilar and interchangeable biosimilar medications over the past 10 years. Both biosimilars and interchangeable biosimilars meet the same high standard of biosimilarity for FDA approval and both are as safe and effective as the reference product.”

An interchangeable status allows a biosimilar product to be swapped with the reference product without involvement from the prescribing provider, depending on state law.

While switching studies were not required under previous FDA guidance, the 2019 document did state that the agency “expects that applications generally will include data from a switching study or studies in one or more appropriate conditions of use.”

However, of the 13 biosimilars that received interchangeability status, 9 did not include switching study data.

“Experience has shown that, for the products approved as biosimilars to date, the risk in terms of safety or diminished efficacy is insignificant following single or multiple switches between a reference product and a biosimilar product,” the FDA stated. The agency’s investigators also conducted a systematic review of switching studies, which found no differences in risk for death, serious adverse events, and treatment discontinuations in participants switched between biosimilars and reference products and those that remained on reference products.

“Additionally, today’s analytical tools can accurately evaluate the structure and effects [of] biologic products, both in the lab (in vitro) and in living organisms (in vivo) with more precision and sensitivity than switching studies,” the agency noted.

The FDA is now calling for commentary on these draft recommendations to be submitted by Aug. 20, 2024.

These studies were previously recommended to demonstrate that switching between the biosimilar and its reference product showed no greater risk than using the reference product alone.

“The recommendations in today’s draft guidance, when finalized, will provide clarity and transparency about the FDA’s thinking and align the review and approval process with existing and emerging science,” said Sarah Yim, MD, director of the FDA’s Office of Therapeutic Biologics and Biosimilars in a statement on June 20. “We have gained valuable experience reviewing both biosimilar and interchangeable biosimilar medications over the past 10 years. Both biosimilars and interchangeable biosimilars meet the same high standard of biosimilarity for FDA approval and both are as safe and effective as the reference product.”

An interchangeable status allows a biosimilar product to be swapped with the reference product without involvement from the prescribing provider, depending on state law.

While switching studies were not required under previous FDA guidance, the 2019 document did state that the agency “expects that applications generally will include data from a switching study or studies in one or more appropriate conditions of use.”

However, of the 13 biosimilars that received interchangeability status, 9 did not include switching study data.

“Experience has shown that, for the products approved as biosimilars to date, the risk in terms of safety or diminished efficacy is insignificant following single or multiple switches between a reference product and a biosimilar product,” the FDA stated. The agency’s investigators also conducted a systematic review of switching studies, which found no differences in risk for death, serious adverse events, and treatment discontinuations in participants switched between biosimilars and reference products and those that remained on reference products.

“Additionally, today’s analytical tools can accurately evaluate the structure and effects [of] biologic products, both in the lab (in vitro) and in living organisms (in vivo) with more precision and sensitivity than switching studies,” the agency noted.

The FDA is now calling for commentary on these draft recommendations to be submitted by Aug. 20, 2024.

TOPLINE:

In men with type 2 diabetes (T2D), higher serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were associated with a lower risk for metabolic dysfunction–associated fatty liver disease (MAFLD), whereas higher progesterone levels were associated with a higher risk. In women with T2D, sex- or thyroid-related hormones were not independently associated with the risk for MAFLD.

METHODOLOGY:

• People with T2D may have FLD, and this study explored the link between sex-related and thyroid-related hormone levels and MAFLD to explore and confirm risk factors.
• The researchers used a 2020 definition of MAFLD, now defined in patients as both hepatic steatosis and the presence of overweight/obesity, T2D, or evidence of metabolic dysfunction in lean individuals.
• This cross-sectional study conducted in one hospital in China included 432 patients hospitalized because of T2D and its complications from January 2018 to April 2020 (median T2D duration, 6 years; mean age, 55.8 years; 247 men and 185 postmenopausal women).
• Researchers measured and later adjusted for potential confounding factors, including weight, height, waist circumference, arterial blood pressure, glycemic parameters, liver function, and lipid profiles.
• They assessed blood levels of sex and thyroid hormones by chemiluminescent immunoassays; MAFLD was diagnosed by either ultrasonography findings of hepatic steatosis or a high liver fat index score (fatty liver index > 60).

TAKEAWAY:

• Overall, 275 (63.7%) patients were diagnosed with MAFLD; after adjusting for potential confounding factors, none of the sex- and thyroid-related hormones were independently associated with the risk for MAFLD in all patients with T2D.
• In men with T2D, higher serum levels of FSH (adjusted odds ratio [aOR], 0.919; P = .019) and LH (aOR, 0.888; P = .022) were associated with a reduced risk for MAFLD.
• Higher serum levels of progesterone were associated with an increased risk for MAFLD in men with T2D (aOR, 8.069; P = .003).
• In women with T2D, sex hormones and thyroid hormones were not significantly linked to the risk of developing MAFLD.

IN PRACTICE:

“Our findings could be used to imply that screening for MAFLD and monitoring sex-related hormones are important for T2D patients, especially in men,” the authors wrote.

This study was led by Weihong Lu, Xiamen Clinical Research Center for Cancer Therapy, Xiamen, China; Shangjian Li, Zhongshan Hospital (Xiamen), Fudan University, Xiamen, China; and Yuhua Li, China University of Mining & Technology-Beijing, Beijing, and was published online in BMC Endocrine Disorders.

LIMITATIONS:

Temporal sequences of the associations between sex-related and thyroid-related hormones and MAFLD were not evaluated because of the cross-sectional nature of the study. The small sample size from a single institution may have introduced selection bias. Serum levels of sex hormone-binding globulin and free testosterone were not assessed. The postmenopausal status of women in the study may have affected the ability to find sex-hormone related associations. The findings can only be limitedly extrapolated to similar patients with T2D but not the general population.

DISCLOSURES:

The study was supported by the Fujian Province Nature Science Foundations, China, and the Guiding Project on Medicine and Health in Xiamen, China. The authors declared no conflicts of interest.

TOPLINE:

An experimental pancreatic gene therapy given to a mouse model of obesity as a one-time, single-dose treatment showed improvements in body composition and fasting glucose comparable with those achieved with the glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide, without the reversal of fat-loss and glycemia improvements that are a key concern with the withdrawal of GLP-1 receptor agonist drugs.

METHODOLOGY:

• The adeno-associated virus–based GLP-1 pancreatic gene therapy is designed to induce durable islet production of GLP-1 peptides that could, in theory, negate the need for regular injections or dosing of conventional GLP-1 receptor agonist drugs.
• With initial preclinical research showing benefits in Yucatan pigs, the authors tested the pancreatic gene therapy in mice representing a validated model of diet-induced obesity.
• The mice were randomized to receive either a single-dose administration of the pancreatic gene therapy (n = 10), daily subcutaneous semaglutide injections (n = 10; 10 nmol/kg/d for 4 weeks), pancreatic gene therapy placebo (n = 8), or a semaglutide placebo (n = 8).
• The gene therapy is designed to be delivered directly to the pancreas with a needle puncture, using a proprietary endoscopic delivery method that is similar to procedures commonly performed by gastrointestinal endoscopists, limiting systemic exposure.
• At 4 weeks, semaglutide was discontinued, and 5 of the 10 mice in that group were randomized to the gene therapy, while the other 5 received placebo.

TAKEAWAY:

• At week 4, the pancreatic gene therapy arm had a reduction in fat mass of 21%, compared with 16% with semaglutide (P < .05; both P < .0001 vs placebo)
• The pancreatic gene therapy and semaglutide groups each preserved lean mass, with a loss of only 5% of body weight (both P < .0001 vs placebo).
• At week 8, mice withdrawn from semaglutide had nearly a full reversal of the fat and lean mass losses observed at 4 weeks, returning to within 1% and 2% below baseline, respectively, while the semaglutide-withdrawn mice treated with gene therapy maintained a fat reduction of 17% (P < .01) and lean mass of 5% (P < .0001).
• Significant improvements in fasting glucose were observed in the gene therapy and semaglutide-treated mice at week 4 (both 18%; P < .0001).
• While semaglutide-withdrawal resulted in a rebound of fasting glucose to baseline at week 8, those who had initially received gene therapy or were switched over to the therapy maintained fasting glucose reductions of 21% and 22% at 8 weeks (P < .0001 and P < .001), respectively.
• No indications of pancreatic inflammation or injury were observed in any of the groups.

IN PRACTICE:

The results suggest the therapy could represent “a reliable, ‘off ramp’ from chronic GLP-1 drugs that allows people to maintain the weight loss and blood sugar benefits, even as they stop taking these medicines,” said first author Harith Rajagopalan, MD, PhD, cofounder and chief executive officer of Fractyl Health, which is developing the gene therapy, in a press statement issued by the company.

The therapy is being developed as a candidate for the treatment of type 2 diabetes and plans are underway for the first in-human study in type 2 diabetes in 2025, Dr. Rajagopalan noted while presenting the results at the American Diabetes Association (ADA)’s 84th scientific sessions.
 

SOURCE:

The study was presented on June 23, 2024, at the annual meeting of the ADA’s 84th scientific sessions (Abstract #261-OR).

LIMITATIONS:

The pancreatic gene therapy is in early development and has not been assessed by any regulatory body for investigational or commercial use.

Asked by an audience member at the ADA presentation if the therapy would be reversible if complications were to arise, Dr. Rajagopalan responded that “there are ways to tune this effect in order to prevent complications from occurring, which we will discuss in due course.”

Also asked about the potential for a positive feedback loop with GLP-1 signaling and insulin signaling, Dr. Rajagopalan noted that “I don’t believe that we have seen any evidence of that risk so far. One could hypothesize, but we have not seen anything [in that regard] that would be a cause for concern.”
 

DISCLOSURES:

The study was funded by Fractyl Health, and Dr. Rajagopalan and the authors declared being employees and stockholders/shareholders of the company.

Halifax, Nova Scotia; American Samoa; Queens, New York; Lansing, Michigan; Gurugram, India. I often ask patients where they’re from. Practicing in San Diego, the answers are a geography lesson. People from around the world come here. I sometimes add the more interesting question: How’d you end up here? Many took the three highways to San Diego: the Navy, the defense industry (like General Dynamics), or followed a partner. My Queens patient had a better answer: Super Bowl XXII. On Sunday, Jan. 31st, 1988, the Redskins played the Broncos in San Diego. John Elway and the Broncos lost, but it didn’t matter. “I was scrapin’ the ice off my windshield that Monday morning when I thought, that’s it. I’m done! I drove to the garage where I worked and quit on the spot. Then I drove home and packed my bags.”

In a paper on how to make life decisions, this guy would be Exhibit A: “Don’t overthink it.” That approach might not be suitable for everyone, or for every decision. It might actually be an example of how not to make life decisions (more on that later). But, is there a best way to go about making big life decisions?

The first treatise on this subject was a paper by one Franklin, Ben in 1772. Providing advice to a friend on how to make a career decision, Franklin argued: “My way is to divide half a sheet of paper by a line into two columns; writing over the one Pro and over the other Con.” This “moral algebra” as he called it was a framework to put rigor to a messy, organic problem.

The flaw in this method is that in the end you have two lists. Then what? Do the length of the lists decide? What if some factors are more important? Well, let’s add tools to help. You could use a spreadsheet and assign weights to each variable. Then sum the values and choose based on that. So if “not scraping ice off your windshield” is twice as important as “doubling your rent,” then you’ve got your answer. But what if you aren’t good at estimating how important things are? Actually, most of us are pretty awful at assigning weights to life variables – having bags of money is the consummate example. Seems important, but because of habituation, it turns out to not be sustainable. Note Exhibit B, our wealthy neighbor who owns a Lambo and G-Wagen (AMG squared, of course), who just parked a Cybertruck in his driveway. Realizing the risk of depending on peoples’ flawed judgment, companies instead use statistical modeling called bootstrap aggregating to “vote” on the weights for variables in a prediction. If you aren’t sure how important a new Rivian or walking to the beach would be, a model can answer that for you! It’s a bit disconcerting, I know. I mean, how can a model know what we’d like? Wait, isn’t that how Netflix picks stuff for you? Exactly.

Ok, so why don’t we just ask our friendly personal AI? “OK, ChatGPT, given what you know about me, where can I have it all?” Alas, here we slam into a glass wall. It seems the answer is out there but even our life-changing magical AI tools fail us. Mathematically, it is impossible to have it all. An illustrative example of this is called the economic “impossible trinity problem.” Even the most sophisticated algorithm cannot find an optional solution to some trinities such as fixed foreign exchange rate, free capital movement, and an independent monetary policy. Economists have concluded you must trade off one to have the other two. Impossible trinities are common in economics and in life. Armistead Maupin in his “Tales of the City” codifies it as Mona’s Law, the essence of which is: You cannot have the perfect job, the perfect partner, and the perfect house at the same time. (See Exhibit C, one Tom Brady).

This brings me to my final point, hard decisions are matters of the heart and experiencing life is the best way to understand its beautiful chaos. If making rash judgments is ill-advised and using technology cannot solve all problems (try asking your AI buddy for the square root of 2 as a fraction) what tools can we use? Maybe try reading more novels. They allow us to experience multiple lifetimes in a short time, which is what we need to learn what matters. Reading Dorothea’s choice at the end of “Middlemarch” is a nice example. Should she give up Lowick Manor and marry the penniless Ladislaw or keep it and use her wealth to help others? Seeing her struggle helps us understand how to answer questions like: Should I give up my academic practice or marry that guy or move to Texas? These cannot be reduced to arithmetic. The only way to know is to know as much of life as possible.

My last visit with my Queens patient was our last together. He’s divorced and moving from San Diego to Gallatin, Tennessee. “I’ve paid my last taxes to California, Doc. I decided that’s it, I’m done!” Perhaps he should have read “The Grapes of Wrath” before he set out for California in the first place.

On Sunday, Jan. 31st, 1988, the Redskins played the Broncos in San Diego. John Elway and the Broncos lost, but it didn’t matter. “I was scrapin’ the ice off my windshield that Monday morning when I thought, that’s it. I’m done! I drove to the garage where I worked and quit on the spot. Then I drove home and packed my bags.”

In a paper on how to make life decisions, this guy would be Exhibit A: “Don’t overthink it.” That approach might not be suitable for everyone, or for every decision. It might actually be an example of how not to make life decisions (more on that later). But, is there a best way to go about making big life decisions?

The first treatise on this subject was a paper by one Franklin, Ben in 1772. Providing advice to a friend on how to make a career decision, Franklin argued: “My way is to divide half a sheet of paper by a line into two columns; writing over the one Pro and over the other Con.” This “moral algebra” as he called it was a framework to put rigor to a messy, organic problem.

The flaw in this method is that in the end you have two lists. Then what? Do the length of the lists decide? What if some factors are more important? Well, let’s add tools to help. You could use a spreadsheet and assign weights to each variable. Then sum the values and choose based on that. So if “not scraping ice off your windshield” is twice as important as “doubling your rent,” then you’ve got your answer. But what if you aren’t good at estimating how important things are? Actually, most of us are pretty awful at assigning weights to life variables – having bags of money is the consummate example. Seems important, but because of habituation, it turns out to not be sustainable. Note Exhibit B, our wealthy neighbor who owns a Lambo and G-Wagen (AMG squared, of course), who just parked a Cybertruck in his driveway. Realizing the risk of depending on peoples’ flawed judgment, companies instead use statistical modeling called bootstrap aggregating to “vote” on the weights for variables in a prediction. If you aren’t sure how important a new Rivian or walking to the beach would be, a model can answer that for you! It’s a bit disconcerting, I know. I mean, how can a model know what we’d like? Wait, isn’t that how Netflix picks stuff for you? Exactly.

Ok, so why don’t we just ask our friendly personal AI? “OK, ChatGPT, given what you know about me, where can I have it all?” Alas, here we slam into a glass wall. It seems the answer is out there but even our life-changing magical AI tools fail us. Mathematically, it is impossible to have it all. An illustrative example of this is called the economic “impossible trinity problem.” Even the most sophisticated algorithm cannot find an optional solution to some trinities such as fixed foreign exchange rate, free capital movement, and an independent monetary policy. Economists have concluded you must trade off one to have the other two. Impossible trinities are common in economics and in life. Armistead Maupin in his “Tales of the City” codifies it as Mona’s Law, the essence of which is: You cannot have the perfect job, the perfect partner, and the perfect house at the same time. (See Exhibit C, one Tom Brady).

This brings me to my final point, hard decisions are matters of the heart and experiencing life is the best way to understand its beautiful chaos. If making rash judgments is ill-advised and using technology cannot solve all problems (try asking your AI buddy for the square root of 2 as a fraction) what tools can we use? Maybe try reading more novels. They allow us to experience multiple lifetimes in a short time, which is what we need to learn what matters. Reading Dorothea’s choice at the end of “Middlemarch” is a nice example. Should she give up Lowick Manor and marry the penniless Ladislaw or keep it and use her wealth to help others? Seeing her struggle helps us understand how to answer questions like: Should I give up my academic practice or marry that guy or move to Texas? These cannot be reduced to arithmetic. The only way to know is to know as much of life as possible.

My last visit with my Queens patient was our last together. He’s divorced and moving from San Diego to Gallatin, Tennessee. “I’ve paid my last taxes to California, Doc. I decided that’s it, I’m done!” Perhaps he should have read “The Grapes of Wrath” before he set out for California in the first place.

MONTREAL – Levels of neurofilament light chain (Nfl) may be a biomarker of chemotherapy-induced peripheral neurotoxicity (CIPN), new research suggests.

Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.

“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”

The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
 

Common, Burdensome Side Effect

A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.

The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.

The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).

Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs. 

Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%. 

Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization. 

In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.

“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park. 

“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”

Dr. Park said the results suggest that NfL may provide a biomarker of long-term axon damage and that Nfl assays “may enable clinicians to evaluate the risk of long-term toxicity early during paclitaxel treatment to hopefully provide clinically significant information to guide better treatment titration.” 

Currently, she said, CIPN is a prominent cause of dose reduction and early chemotherapy cessation. 

“For example, in early breast cancer around 25% of patients experience a dose reduction due to the severity of neuropathy symptoms.” But, she said, “there is no standardized way of identifying which patients are at risk of long-term neuropathy and therefore, may benefit more from dose reduction. In this setting, a biomarker such as Nfl could provide oncologists with more information about the risk of long-term toxicity and take that into account in dose decision-making.” 

For some cancers, she added, there are multiple potential therapy options.

“A biomarker such as NfL could assist in determining risk-benefit profile in terms of switching to alternate therapies. However, further studies will be needed to fully define the utility of NfL as a biomarker of paclitaxel neuropathy.” 
 

Promising Research

Commenting on the research for this news organization, Maryam Lustberg, MD, associate professor, director of the Center for Breast Cancer at Smilow Cancer Hospital and Yale Cancer Center, and chief of Breast Medical Oncology at Yale Cancer Center, in New Haven, Connecticut, said the study “builds on a body of work previously reported by others showing that neurofilament light chains as detected in the blood can be associated with early signs of neurotoxic injury.” 

She added that the research “is promising, since existing clinical and patient-reported measures tend to under-detect chemotherapy-induced neuropathy until more permanent injury might have occurred.” 

Dr. Lustberg, who is immediate past president of the Multinational Association of Supportive Care in Cancer, said future studies are needed before Nfl testing can be implemented in routine practice, but that “early detection will allow earlier initiation of supportive care strategies such as physical therapy and exercise, as well as dose modifications, which may be helpful for preventing permanent damage and improving quality of life.” 

The investigators and Dr. Lustberg report no relevant financial relationships.

The Centers for Medicare & Medicaid Services (CMS) has announced the conclusion of a program that provided billions in early Medicare payments to those affected by the Change Healthcare/UnitedHealth Group cyberattack last winter. The Accelerated and Advance Payment program, which began in early March to assist hospitals and practices facing significant reimbursement delays, will stop accepting applications after July 12, 2024.

CMS reported that the program advanced more than $2.55 billion in Medicare payments to > 4200 Part A providers, including hospitals, and more than $717.18 million in payments to Part B suppliers such as physicians, nonphysician practitioners, and durable medical equipment suppliers.

According to CMS, the Medicare billing system is now functioning properly, and 96% of the early payments have been recovered. The advances were to represent ≤ 30 days of typical claims payments in a 3-month period of 2023, with full repayment expected within 90 days through “automatic recoupment from Medicare claims” — no extensions allowed.

The agency took a victory lap regarding its response. “In the face of one of the most widespread cyberattacks on the US health care industry, CMS promptly took action to get providers and suppliers access to the funds they needed to continue providing patients with vital care,” CMS Administrator Chiquita Brooks-LaSure said in a statement. “Our efforts helped minimize the disruptive fallout from this incident, and we will remain vigilant to be ready to address future events.”

Ongoing Concerns from Health Care Organizations

Ben Teicher, an American Hospital Association spokesman, said that the organization hopes that CMS will be responsive if there’s more need for action after the advance payment program expires. The organization represents about 5000 hospitals, health care systems, and other providers.

“Our members report that the aftereffects of this event will likely be felt throughout the remainder of the year,” he said. According to Teicher, hospitals remain concerned about their ability to process claims and appeal denials, the safety of reconnecting to cyber services, and access to information needed to bill patients and reconcile payments.

In addition, hospitals are concerned about “financial support to mitigate the considerable costs incurred as a result of the cyberattack,” he said.

Charlene MacDonald, executive vice-president of public affairs at the Federation of American Hospitals, which represents more than 1000 for-profit hospitals, sent a statement to this news organization that said some providers “are still feeling the effects of care denials and delays caused by insurer inaction.

“We appreciate that the Administration acted within its authority to support providers during this unprecedented crisis and blunt these devastating impacts, especially because a vast majority of managed care companies failed to step up to the plate,” she said. “It is now time to shift our focus to holding plans accountable for using tactics to delay and deny needed patient care.”

Cyberattack Impact and Response

The ransom-based cyberattack against Change Healthcare/UnitedHealth Group targeted an electronic data interchange clearing house processing payer reimbursement systems, disrupting cash flows at hospitals and medical practices, and affecting patient access to prescriptions and life-saving therapy.

Change Healthcare — part of the UnitedHealth Group subsidiary Optum — processes half of all medical claims, according to a Department of Justice lawsuit. The American Hospital Association described the cyberattack as “the most significant and consequential incident of its kind” in US history.

By late March, UnitedHealth Group said nearly all medical and pharmacy claims were processing properly, while a deputy secretary of the US Department of Health & Human Services told clinicians that officials were focusing on the last group of clinicians who were facing cash-flow problems.

Still, a senior advisor with CMS told providers at that time that “we have heard from so many providers over the last several weeks who are really struggling to make ends meet right now or who are worried that they will not be able to make payroll in the weeks to come.”

The advances were to represent ≤ 30 days of typical claims payments in a 3-month period of 2023, with full repayment expected within 90 days through “automatic recoupment from Medicare claims” — no extensions allowed.

The agency took a victory lap regarding its response. “In the face of one of the most widespread cyberattacks on the US health care industry, CMS promptly took action to get providers and suppliers access to the funds they needed to continue providing patients with vital care,” CMS Administrator Chiquita Brooks-LaSure said in a statement. “Our efforts helped minimize the disruptive fallout from this incident, and we will remain vigilant to be ready to address future events.”

Ongoing Concerns from Health Care Organizations

Ben Teicher, an American Hospital Association spokesman, said that the organization hopes that CMS will be responsive if there’s more need for action after the advance payment program expires. The organization represents about 5000 hospitals, health care systems, and other providers.

“Our members report that the aftereffects of this event will likely be felt throughout the remainder of the year,” he said. According to Teicher, hospitals remain concerned about their ability to process claims and appeal denials, the safety of reconnecting to cyber services, and access to information needed to bill patients and reconcile payments.

In addition, hospitals are concerned about “financial support to mitigate the considerable costs incurred as a result of the cyberattack,” he said.

Charlene MacDonald, executive vice-president of public affairs at the Federation of American Hospitals, which represents more than 1000 for-profit hospitals, sent a statement to this news organization that said some providers “are still feeling the effects of care denials and delays caused by insurer inaction.

“We appreciate that the Administration acted within its authority to support providers during this unprecedented crisis and blunt these devastating impacts, especially because a vast majority of managed care companies failed to step up to the plate,” she said. “It is now time to shift our focus to holding plans accountable for using tactics to delay and deny needed patient care.”

Cyberattack Impact and Response

The ransom-based cyberattack against Change Healthcare/UnitedHealth Group targeted an electronic data interchange clearing house processing payer reimbursement systems, disrupting cash flows at hospitals and medical practices, and affecting patient access to prescriptions and life-saving therapy.

Change Healthcare — part of the UnitedHealth Group subsidiary Optum — processes half of all medical claims, according to a Department of Justice lawsuit. The American Hospital Association described the cyberattack as “the most significant and consequential incident of its kind” in US history.

By late March, UnitedHealth Group said nearly all medical and pharmacy claims were processing properly, while a deputy secretary of the US Department of Health & Human Services told clinicians that officials were focusing on the last group of clinicians who were facing cash-flow problems.

Still, a senior advisor with CMS told providers at that time that “we have heard from so many providers over the last several weeks who are really struggling to make ends meet right now or who are worried that they will not be able to make payroll in the weeks to come.”

Glucagon-like peptide 1 (GLP-1) receptor agonists such as semaglutide (marketed as Ozempic and Rybelsus for type 2 diabetes and as Wegovy for obesity) slow down digestion and curb hunger by working on the brain’s dopamine reward center. They are prescribed to promote weight loss, metabolic health in type 2 diabetes, and heart health in coronary artery disease.

Semaglutide can be prescribed in two forms: the brand-name version, which is approved and confirmed as safe and effective by the US Food and Drug Administration (FDA), and the versions that can be obtained from a compounding pharmacy. Compounding pharmacies are permitted by the FDA to produce what is “ essentially a copy” of approved medications when there’s an official shortage, which is currently the case with semaglutide and other GLP-1 receptor agonists.

Patients are often drawn to compounding pharmacies for pricing-related reasons. If semaglutide is prescribed for a clear indication like diabetes and is covered by insurance, the brand-name version is commonly dispensed. However, if it’s not covered, patients need to pay out of pocket for branded versions, which carry a monthly cost of $1000 or more. Alternatively, their doctors can prescribe compounded semaglutide, which some telehealth companies advertise at costs of approximately $150-$300 per month.
 

Potential Issues With Compounded Semaglutide 

Compounding pharmacies produce drugs from raw materials containing active pharmaceutical ingredients (APIs). Although compounders use many of the same ingredients found in brand-name medications, for drugs like semaglutide, they may opt for specific salts that are not identical to those involved in the production of the standard versions. These salts are typically reserved for research purposes and may not be suitable for general use.

In late 2023, the FDA issued a letter asking the public to exercise caution when using compounded products containing semaglutide or semaglutide salts. This was followed in January 2024 by an FDA communication citing adverse events reported with the use of compounded semaglutide and advising patients to avoid these versions if an approved form of the drug is available.
 

Compound Pharmacies: A Closer Look 

Compounding pharmacies have exploded in popularity in the past several decades. The compounding pharmacy market is expected to grow at 7.8% per year over the next decade. 

Historically, compounding pharmacies have filled a niche for specialty vitamins for intravenous administration as well as chemotherapy medications. They also offer controlled substances, such as ketamine lozenges and nasal sprays, which are unavailable or are in short supply from traditional manufacturers.

Compounding pharmacies fall into two categories. First are compounding pharmacies covered under Section 503A of the Federal Food, Drug and Cosmetic Act; these drugs are neither tested nor monitored. Such facilities do not have to report adverse events to the FDA. The second category is Section 503B outsourcing facilities. These pharmacies choose to be tested by, to be inspected by, and to report adverse events to the FDA. 
 

The FDA’s Latest Update on This Issue

This news organization contacted the FDA for an update on the adverse events reported about compounded semaglutide. From August 8, 2021, to March 31, 2024, they received more than 20,000 adverse events reports for FDA-approved semaglutide. Comparatively, there were 210 adverse events reported on compounded semaglutide products. 

The FDA went on to describe that many of the adverse events reported were consistent with known reactions in the labeling, like nausea, diarrhea, and headache. Yet, they added that, “the FDA is unable to determine how, or if, other factors may have contributed to these adverse events, such as differences in ingredients and formulation between FDA-approved and compounded semaglutide products.” They also noted there was variation in the data quality in the reports they have received, which came only from 503B compounding pharmacies.

In conclusion, given the concerns about compounded semaglutide, it is prudent for the prescribing physicians as well as the patients taking the medication to know that risks are “higher” according to the FDA. We eagerly await more specific information from the FDA to better understand reported adverse events. 
 

How to Help Patients Receive Safe Compounded Semaglutide 

For clinicians considering prescribing semaglutide from compounding pharmacies, there are several questions worth asking, according to the Alliance for Pharmacy Compounding. First, find out whether the pharmacy complies with United States Pharmacopeia compounding standards and whether they source their APIs from FDA-registered facilities, the latter being required by federal law. It’s also important to ensure that these facilities undergo periodic third-party testing to verify medication purity and dosing. 

Ask whether the pharmacy is accredited by the Pharmacy Compounding Accreditation Board (PCAB). Accreditation from the PCAB means that pharmacies have been assessed for processes related to continuous quality improvement. In addition, ask whether the pharmacy is designated as a 503B compounder and if not, why.

Finally, interviewing the pharmacist themselves can provide useful information about staffing, training, and their methods of preparing medications. For example, if they are preparing a sterile eye drop, it is important to ask about sterility testing.
