Obesity

The FDA is formally looking into reports that some people who took popular diabetes and weight loss drugs had suicidal thoughts or two other health problems.

A new FDA report listed potential links between the medications and alopecia, aspiration, or suicidal ideation, CBS News reported. The investigation centers on reports of the health problems among people taking GLP-1 receptor agonists, some of which are Ozempic, Wegovy, Mounjaro, and Zepbound. The drugs are used to treat diabetes and overweight or obesity.

An investigation by the FDA doesn’t mean that the FDA has concluded a risk exists, the FDA’s webpage for risk evaluation cautions.

“It means that FDA has identified a potential safety issue, but it does not mean that FDA has identified a causal relationship between the drug and the listed risk,” the FDA site states.

Possible next steps after an investigation could include updating drug labels with new information, putting a risk management plan in place to prevent or manage the health risks, or gathering more information.

“The FDA monitors the safety of drugs throughout their life cycle,” even after the drugs are approved. In addition, the FDA uses “surveillance and risk assessment programs to identify and evaluate adverse events that did not appear during the drug development process,” FDA spokesperson Chanapa Tantibanchachai said in an email published by multiple news outlets.

Although an investigation may lead to no changes in how a drug is regulated by the FDA, this isn’t the first time that the popular medicines have landed on the FDA’s radar for safety reevaluation. Last year, the label for the drug Ozempic was updated to acknowledge reports of intestinal obstructions, CBS News reported.

European regulators are also looking into reports of suicidal thoughts among people taking GLP-1 receptor agonists, although no link has been established.

Concerns about aspiration during surgery resulted in the American Society of Anesthesiologists advising in June that people should stop taking GLP-1 receptor agonists before they have elective surgeries.

“While there is currently a lack of scientific data on how GLP-1 receptor agonists affect patients having surgery and interact with anesthesia, we’ve received anecdotal reports that the delay in stomach emptying could be associated with an increased risk of regurgitation and aspiration of food into the airways and lungs during general anesthesia and deep sedation,” the society’s president, Michael W. Champeau, MD, said in a statement at the time.

According to CBS News, the FDA’s drug reporting system links the medications to 201 reports of suicide or suicidal ideation, 18 reports that mention aspiration, and 422 reports that mention alopecia.

Novo Nordisk, whose portfolio includes Wegovy and Ozempic, told CNN that it works with the FDA to monitor safety and is aware of the reports of side effects.

“Novo Nordisk stands behind the safety and efficacy of all of our GLP-1RA medicines when they are used as indicated and when they are taken under the care of a licensed healthcare professional,” the company said in a statement to CNN.

A spokesperson for Eli Lilly, which makes Mounjaro and Zepbound, told CBS News in a statement, “Currently, the FDA is reviewing data on certain potential risks for GLP-1 receptor agonist medicines. Patient safety is our priority, and we are collaborating with the FDA on these potential signals.”

TOPLINE:

Light physical activity during childhood may lower blood cholesterol levels more effectively than moderate to vigorous physical activity, regardless of body fat mass.

METHODOLOGY:

• Researchers analyzed the data of 792 children (58% females) from the Avon Longitudinal Study of Parents and Children (ALSPAC) UK birth cohort.
• The measures included accelerometer-based sedentary time, light physical activity, and moderate to vigorous physical activity at ages 11, 15, and 24 years.
• The children had complete measurements of fasting high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride, and total cholesterol levels at ages 15 , 17, and 24 years.
• Data also included measures of body mass, composition (fat and lean mass), insulin resistance, inflammation, and other cardiometabolic, socioeconomic, and lifestyle factors.
• The researchers conducted two types of analyses: Mediation path, to examine how fat and lean body mass affected longitudinal associations of activity level with blood lipids over 13 years, and temporal path, to look at temporal relationships between activity and lipid levels at ages 15 and 24 years only.

TAKEAWAY:

• Higher cumulative light physical activity from childhood through young adulthood was associated with a fivefold to eightfold decrease in total cholesterol, while total body fat mass decreased the impact of light physical activity on total cholesterol by 6%.
• Higher cumulative moderate to vigorous physical activity over 13 years led to a modest decrease in total cholesterol, an effect reduced to nonsignificance by the presence of higher fat mass.
• More cumulative sedentary time was associated with increasing total cholesterol.

IN PRACTICE:

“Light physical activity provides an opportunity for persons with obesity to follow a path to potentially benefit from the lipid-lowering effect of mild exercise,» wrote the author.

SOURCE:

Andrew O. Agbaje, from the Institute of Public Health and Clinical Nutrition, School of Medicine, University of Eastern Finland, Kuopio, Finland, conducted this study. It was published online December 14, 2023, in the Journal of Clinical Endocrinology and Metabolism.

LIMITATIONS:

The study included mostly White participants, so the findings might not apply to diverse racial and ethnic groups. The accelerometer data were gathered using a 60-second epoch, a duration known to underestimate moderate to vigorous physical activity in pediatric populations. There were no measures of fasting plasma lipids at age 11 years. The study also lacked data on participants’ dietary habits, alcohol intake, and menstrual cycle.

DISCLOSURES:

The ALSPAC UK birth cohort is funded by the UK Medical Research Council, the Wellcome Trust, and the University of Bristol. The author is funded by multiple foundations. No conflicts of interest were reported.

While adults, many of whom don’t meet the clinical definition of obesity, scramble to procure glucagon-like peptide 1 (GLP-1) agonists for weight loss, pediatric obesity specialists said their young patients who could benefit more over the long term often are unable to access the potentially life-altering medications.

The US Food and Drug Administration (FDA) approved two GLP-1 agonists — both marketed by Novo Nordisk — for use in adolescents aged ≥ 12 years: Wegovy (semaglutide) in December 2022 and Saxenda (liraglutide) in December 2020. Novo Nordisk and Eli Lilly — which makes the dual glucose-dependent insulinotropic polypetide/GLP-1 agonist tirzepatide (Zepbound) — are also investigating the drugs for obesity in children as young as age 6 years. The crushing demand for semaglutide in the last year — driving a thriving market in compounded versions and online prescriptions — has made it increasingly difficult to find pharmacies that can fill prescriptions, pediatricians told this news organization.

“It’s been more difficult to get people initiated now than it was a year ago,” said Brooke Sweeney, MD, medical director of weight management services at Children’s Mercy in Kansas City, Missouri. “Because of the supply issues, for the most part we›re not starting anyone new because I don›t have enough medication to keep my patients on it who are already on it,” she said.

Sarah Raatz, MD, a pediatrician at the University of Minnesota’s Center for Pediatric Obesity Medicine, said, “I actually haven’t really been prescribing many of these medications as of late.” Both liraglutide and semaglutide “are largely unavailable or quite hard to get a hold of,” Dr. Raatz told this news organization.

Susma Shanti Vaidya, MPH, MD, associate medical director of the IDEAL pediatric obesity clinic at Children›s National Hospital in Washington, DC, said that patients taking GLP-1 agonists in her practice have reduced their body mass index and have seen resolution of prediabetes, diabetes, and fatty liver disease. «I had one patient who had severe obstructive sleep apnea which resolved with semaglutide.»

But when they can’t find the medications, it can lead to a plateauing of weight loss and a reversal of hard-won victories, Dr. Vaidya said.

Insurance Denials Also Growing

In January 2023, the American Academy of Pediatrics urged aggressive treatment of childhood obesity, including using FDA-approved medications such as GLP-1 agonists combined with lifestyle and dietary modifications.

The US Preventive Services Task Force, however, has issued a draft proposal that recommends a variety of lifestyle and behavior modification interventions for children and adolescents but says the evidence does not yet support recommending bariatric surgery or medications.

Insurance coverage for children — even for FDA-approved indications and the age 12-and-over population — has become increasingly difficult, said the pediatric obesity specialists. Insurers are also creating hurdles that make getting coverage more difficult, they said.

Some insurers track an adolescent’s weight trajectory, “and if they’re not meeting a certain response threshold set by the insurance company, then they can pull coverage and then we have to try to advocate for why continued coverage might be beneficial and necessary,” Dr. Raatz said.

Insurers in the region around Children’s Mercy are erecting similar barriers, said Sweeney. Interim weight loss goals are challenging in pediatrics — given that adolescents are constantly changing and growing, she said.

Dr. Vaidya said she’s had success with commercial insurers but that the Washington, DC, and Maryland Medicaid programs have been stingier.

All the pediatricians said they expect greater restrictions in 2024.

Dr. Vaidya said some patients told her they had been notified that prior authorization will be required for new prescriptions for a GLP-1 agonist.

“We will just kind of be forced to see what happens when these medications are taken away from patients who have benefited from them,” Dr. Raatz said.
 

Some Parents Asking for GLP-1 Agonists

Pediatric obesity specialists said more parents are asking if a GLP-1 agonist might be appropriate for their children this year than in 2022.

Dr. Sweeney said parents ask for the medications when they feel they have exhausted all other options for their children. “These parents are not coming because they are concerned about the cosmetic effects of the weight,” she said. In most cases, children she sees have been struggling for years with extreme hunger and lack of satiety and may have prediabetes or diabetes. Many are being bullied in school because of their weight. They have only marginally been helped by interventions suggested by primary care or dietitians or other specialists, Dr. Sweeney said.

“Starting semaglutide really is life-changing for some of these patients,” Dr. Vaidya said. One patient said, “it just stopped the food chatter,” she added, noting that the adolescent no longer felt ruled by cravings.

In a recent poll by Morning Consult, 65% of parents of children with weight-related issues said they would be interested in GLP-1 agonists for their kids. A third of all parents said they would be interested in having their children use the drugs if they were available.
 

Lifelong Medication?

Parents — and adolescents — are generally counseled that obesity is a chronic disease and GLP-1 agonists are likely a lifelong treatment.

With the medications, “our first step is to get induction of weight loss and get your set point decreased enough that we can get you to a healthier weight for your body,” Dr. Sweeney said.

She tells patients and families, “I can’t tell you that you’re necessarily going to be on this medication at this dose for the rest of your life, but you will need treatment for life.”

Based on current knowledge, the risks for lifelong obesity outweigh the risk for the medications. Dr. Sweeney said she would like to see more data. “There absolutely is an evidence gap, and we need more information on the long-term effectiveness and safety.”

“When we start kids on this medication, I’m very clear that we are going to try to get to the lowest effective dose,” Dr. Vaidya said. She also emphasizes to parents that the medications must be used in conjunction with continued lifestyle modifications. She expressed hope that as clinicians gain more experience, and patients’ comorbidities resolve, perhaps it will be possible in some cases to take individuals “off for a period of time, with the understanding that they might have to go back on in a few months.”

“We’re weighing the pros and cons of being on a medication long term but we’re also weighing the pros and cons of weight-related health complications long term,” Dr. Raatz said.

Dr. Raatz also said clinicians have much to learn about the long-term safety of GLP-1 agonists in their pediatric patients.

She tells parents and families, “we expect that this is going to be a long-term medication, and this is going to be something that we’re going to continue to monitor.”

Dr. Sweeney reports that she is a speaker and unpaid consultant on Rhythm Pharmaceuticals’ Imcivree (setmelanotide) medication and that she consults for Eli Lilly. Dr. Raatz is a coprincipal investigator for a Novo Nordisk trial of semaglutide in young children and will be a co-PI for a similar trial for Eli Lilly’s tirzepatide but receives no consulting fees or honoraria. Dr. Vaidya reported no conflicts.

Some insurers track an adolescent’s weight trajectory, “and if they’re not meeting a certain response threshold set by the insurance company, then they can pull coverage and then we have to try to advocate for why continued coverage might be beneficial and necessary,” Dr. Raatz said.

Insurers in the region around Children’s Mercy are erecting similar barriers, said Sweeney. Interim weight loss goals are challenging in pediatrics — given that adolescents are constantly changing and growing, she said.

Dr. Vaidya said she’s had success with commercial insurers but that the Washington, DC, and Maryland Medicaid programs have been stingier.

All the pediatricians said they expect greater restrictions in 2024.

Dr. Vaidya said some patients told her they had been notified that prior authorization will be required for new prescriptions for a GLP-1 agonist.

“We will just kind of be forced to see what happens when these medications are taken away from patients who have benefited from them,” Dr. Raatz said.
 

Some Parents Asking for GLP-1 Agonists

Pediatric obesity specialists said more parents are asking if a GLP-1 agonist might be appropriate for their children this year than in 2022.

Dr. Sweeney said parents ask for the medications when they feel they have exhausted all other options for their children. “These parents are not coming because they are concerned about the cosmetic effects of the weight,” she said. In most cases, children she sees have been struggling for years with extreme hunger and lack of satiety and may have prediabetes or diabetes. Many are being bullied in school because of their weight. They have only marginally been helped by interventions suggested by primary care or dietitians or other specialists, Dr. Sweeney said.

“Starting semaglutide really is life-changing for some of these patients,” Dr. Vaidya said. One patient said, “it just stopped the food chatter,” she added, noting that the adolescent no longer felt ruled by cravings.

In a recent poll by Morning Consult, 65% of parents of children with weight-related issues said they would be interested in GLP-1 agonists for their kids. A third of all parents said they would be interested in having their children use the drugs if they were available.
 

Lifelong Medication?

Parents — and adolescents — are generally counseled that obesity is a chronic disease and GLP-1 agonists are likely a lifelong treatment.

With the medications, “our first step is to get induction of weight loss and get your set point decreased enough that we can get you to a healthier weight for your body,” Dr. Sweeney said.

She tells patients and families, “I can’t tell you that you’re necessarily going to be on this medication at this dose for the rest of your life, but you will need treatment for life.”

Based on current knowledge, the risks for lifelong obesity outweigh the risk for the medications. Dr. Sweeney said she would like to see more data. “There absolutely is an evidence gap, and we need more information on the long-term effectiveness and safety.”

“When we start kids on this medication, I’m very clear that we are going to try to get to the lowest effective dose,” Dr. Vaidya said. She also emphasizes to parents that the medications must be used in conjunction with continued lifestyle modifications. She expressed hope that as clinicians gain more experience, and patients’ comorbidities resolve, perhaps it will be possible in some cases to take individuals “off for a period of time, with the understanding that they might have to go back on in a few months.”

“We’re weighing the pros and cons of being on a medication long term but we’re also weighing the pros and cons of weight-related health complications long term,” Dr. Raatz said.

Dr. Raatz also said clinicians have much to learn about the long-term safety of GLP-1 agonists in their pediatric patients.

She tells parents and families, “we expect that this is going to be a long-term medication, and this is going to be something that we’re going to continue to monitor.”

Dr. Sweeney reports that she is a speaker and unpaid consultant on Rhythm Pharmaceuticals’ Imcivree (setmelanotide) medication and that she consults for Eli Lilly. Dr. Raatz is a coprincipal investigator for a Novo Nordisk trial of semaglutide in young children and will be a co-PI for a similar trial for Eli Lilly’s tirzepatide but receives no consulting fees or honoraria. Dr. Vaidya reported no conflicts.

Weight-loss drugs should be covered by Medicare and by other health insurance, according to a poll of US adults aged 50-80 years.

Among more than 2600 polled, 83% say that health insurance should cover prescription weight-loss drugs that have been approved by the US Food and Drug Administration (FDA), and 76% say Medicare should cover such drugs. However, only 30% would be willing to pay higher Medicare premiums to have these medications covered.

Among the 27% of respondents who say they are overweight, 63% are interested in taking such medications, as are 45% of those with diabetes, regardless of weight.

The University of Michigan (U-M) National Poll on Healthy Aging was  published online  on December 13, 2023.

High Awareness

The findings come at a time when injectable glucagon-like peptide 1 receptor agonists (GLP-1 RAs), such as Ozempic, Wegovy, Zepbound, and Mounjaro, are receiving a lot of public attention, the university noted.

Overall, 64% of survey respondents had heard of at least one prescription medication used for weight management. 

By brand name, 61% had heard of Ozempic, approved for the treatment of  type 2 diabetes  but prescribed off label for weight loss; 18% had heard of Wegovy; and 13% had heard of the anorexiant drug  phentermine .

Very few respondents (3% for each) had heard of the GLP-1 RA Saxenda, Qsymia (phentermine plus the anticonvulsant  topiramate ), and the opiate antagonist Contrave. 

Zepbound, the  obesity -specific form of the diabetes drug Mounjaro, received FDA approval after the poll was taken and was not included in survey questions.

Among respondents who had heard of at least one prescription medication used for weight management, 58% had heard about them through the news (eg, TV, magazines, newspapers) and 53% had heard about them from an advertisement on TV, the Internet, or radio. Only 11% heard about them from their healthcare providers.

Respondents more likely to be interested in taking a prescription medication for weight management included women, those aged 50-64 years, Black persons, Hispanic persons, those with household incomes of less than $60,000 annually, those with lower levels of education, those in fair or poor physical or mental health, and those with a health problem or disability limiting their daily activities.

Spotty Coverage

The GLP-1 RAs can cost more than $12,000 a year for people who pay out of pocket, the university noted. 

A  Medicare Part D law  passed in 2003 prohibits Medicare from covering medications for weight loss, although currently it can cover such drugs to help people with type 2 diabetes manage their weight. 

Medicaid covers the cost of antiobesity drugs in some states. 

Most private plans and the  Veterans Health Administration  cover them, but with restrictions due to high monthly costs for the newer medications.

The American Medical Association recently  called on insurers  to cover evidence-based weight-loss medications.

The strong demand for these medications, including for off-label purposes by people willing to pay full price, has created major shortages, the university noted. 

“As these medications grow in awareness and use, and insurers make decisions about coverage, it’s crucial for patients who have obesity or diabetes, or who are overweight with other health problems, to talk with their healthcare providers about their options,” said poll director Jeffrey Kullgren, MD, MPH, MS, a primary care physician at the VA Ann Arbor Healthcare System and associate professor of internal medicine at U-M.

Other weight-management strategies that respondents think should be covered by health insurance include sessions with a registered dietitian or nutritionist (85%);  weight-loss surgery  (73%); gym or fitness facility memberships (65%); apps or online programs to track diet, exercise, and/or behavior change (58%); and sessions with a personal trainer (53%).

The randomly selected nationally representative household survey of 2657 adults was conducted from July 17 to August 7, 2023, by NORC at the University of Chicago for the U-M Institute for Healthcare Policy and Innovation. The sample was subsequently weighted to reflect population figures from the US Census Bureau. The completion rate was 50% among those contacted to participate. The margin of error is ±1 to 5 percentage points for questions asked of the full sample and higher among subgroups.

The poll is based at the U-M Institute for Healthcare Policy and Innovation and supported by AARP and Michigan Medicine, the University of Michigan’s academic medical center.

TOPLINE:

A high-quality, low-carbohydrate diet (LCD), rich in plant-based proteins and healthy fats, was associated with slower weight gain, while a lower-quality LCD was associated with the reverse.

METHODOLOGY:

• Prospective cohort study included 123,332 participants from the Nurses’ Health Studies (NHS, 1986-2010 and 1991-2015) and the Health Professionals Follow-up Study (HPFS, 1986-2018).
• Diets assessed by questionnaires were categorized as: (1) total LCD (TLCD), emphasizing overall lower carbohydrate intake; (2) animal-based LCD (ALCD), emphasizing animal-sourced protein and fat; (3) vegetable-based LCD (VLCD), emphasizing plant-sourced protein and fat; (4) a healthy LCD (HLCD), emphasizing less refined carbohydrates, more plant protein, and healthy fat; and (5) unhealthy LCD (ULCD), emphasizing less healthful carbohydrates, more animal protein, and unhealthy fat.
• The primary outcome was 4-year reported changes in body weight, divided into quintiles, with Q3 = no change, Q1 = largest decrease, and Q5 = largest increase.

TAKEAWAY:

• Participants gained a mean of 1.3 kg over each 4-year interval, with gains of 0.8, 1.8, and 0.5 kg for NHS, NHSII, and HPFS, respectively.
• After adjustment for baseline and concomitant changes in lifestyle and demographic factors, compared with participants with no change in the TLCD score over 4-year intervals, those with the largest increase (Q5) in the TLCD score did not have significant weight change (0.03 kg), while those with the largest decrease (Q1) in the TLCD score had significantly less weight gain (−0.20 kg).
• Similarly, those following a VLCD with Q5 change, compared with those with stable Q3 adherence, experienced 0.21 kg less weight gain, and those with Q1 change experienced 0.17 kg less weight gain, both significant.
• Adhering to an ALCD was associated with more weight gain over time, with each 1 standard deviation (SD) increase in ALCD associated with a significant 0.13 kg more weight gain over 4-year intervals.
• Opposite results were seen for ULCD and HLCD scores, where a 1-SD increase in HLCD and ULCD was associated with a significant 0.36 kg weight loss and 0.39 kg weight gain, respectively, over 4-year intervals.
• The associations were stronger among individuals with baseline body mass index ≥ 30 kg/m².

IN PRACTICE:

“The findings of this cohort study underscore the importance of diet quality within LCD patterns for weight management… Overall, the study findings argue against the sole focus of macronutrient quantity for weight management and suggest the crucial role of nutrient quality in maintaining a healthy body weight.”

• Observational study, potential for residual confounding.
• No body composition measurement.
• Study population was mainly White health professionals.

The glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide has made headlines as a US Food and Drug Administration (FDA)–approved treatment for type 2 diabetes (Ozempic) and obesity (Wegovy). 

Recently, attention has turned to the possibility that semaglutide may have broader applications, including its potential positive impact on addictive behaviors such as reducing drug craving and alcohol consumption. 

“There is some really interesting preclinical research in rodents and monkeys that shows that GLP-1 agonist molecules, like semaglutide, have the effect of reducing the consumption of not just food, but also alcohol, nicotine, cocaine and amphetamines,” Kyle Simmons, PhD, professor of pharmacology and physiology at Oklahoma State University Center for Health Sciences in Tulsa, said in an interview. 

Some of that early research was conducted by Elisabet Jerlhag Holm, PhD, and colleagues at University of Gothenburg, Sweden.

“We have worked on GLP-1 and alcohol since 2012, and observe promising effects,” Holm told this news organization. 

Her team published two studies earlier this year — one in one in Frontiers in Pharmacology and the other in eBioMedicine — demonstrating that semaglutide, in low doses, reduces alcohol intake in male and female rats.

“We have shown that semaglutide binds to the nucleus accumbens — an area of the brain associated with reward. We have also shown that semaglutide alters the dopamine metabolism when alcohol is on board. This provides a tentative mechanism,” Dr. Holm said. 

First Human Data 

The preclinical data fueled interest in testing the value of the GLP-1 agonist in patient populations with addiction.

Dr. Simmons and colleagues have now published what is believed to be the first evidence in humans that semaglutide specifically reduces the symptoms of alcohol use disorder (AUD).

In a report published online on November 27 in The Journal of Clinical Psychiatry, they describe six patients (of whom five are female; mean age, 43 years) who received semaglutide treatment in the course of pharmacotherapy for weight loss.

All six screened positive for AUD on the Alcohol Use Disorders Identification Test (AUDIT), and all six showed significant improvement in their alcohol-related symptoms after starting semaglutide. 

An AUDIT score > 8 is considered positive. The mean AUDIT score at baseline was 14. It fell to 4.5 on average after semaglutide treatment. The mean 9.5-point decrease in AUDIT scores with semaglutide was statistically significant (P < .001). 

The patients were followed up from a few weeks to almost 9 months, and all of them had a reduction in AUD symptoms. At the various follow-up time points, all six patients had AUDIT scores consistent with “low-risk” drinking.

Strong Response at Low Doses 

“There was a very strong response, even at a very low dose,” lead author Jesse Richards, DO, director of obesity medicine and assistant professor of medicine University of Oklahoma School of Community Medicine, Tulsa, said in an interview. 

Three patients were treated with 0.5 mg of semaglutide weekly, two with 0.25 mg weekly, and one with 1 mg weekly. These doses are lower than those currently approved for treatment of type 2 diabetes and obesity. 

Dr. Holm is not surprised by the results in these six patients. “Based on our preclinical data, this outcome is expected. The data are promising and bigger studies needed,” she said.

Simmons is currently leading a randomized placebo-controlled trial to further test the impact of semaglutide on AUD. 

The STAR (Semaglutide Therapy for Alcohol Reduction) study is funded by the Hardesty Family Foundation and Oklahoma State University Center for Health Sciences.

A sister study is also currently underway in Baltimore, funded by the National Institute on Drug Abuse.

Hopefully, these studies will be able to “definitively tell us whether semaglutide is safe and effective for treatment” for AUD, Dr. Simmons said in a statement. 

Despite being a major cause of preventable death worldwide, AUD currently has only three FDA-approved pharmacotherapies. However, there has been limited uptake of these drugs. 

“There remains a significant treatment gap and need for new and novel or perhaps better tolerated or different mechanism treatment options for patients,” Dr. Richards said. 

The preclinical and early clinical data provide a “signal” of a treatment effect for semaglutide in AUD, Dr. Richards said. The randomized controlled trials now underway should be concluding in the next 1-2 years, “at which point we’ll have a much better sense of the safety and efficacy of this drug for AUD,” he said. 

The case series had no specific funding. Dr. Richards is on speakers bureaus for Rhythm Pharmaceuticals and Novo Nordisk and is on an advisory board for Rhythm Pharmaceuticals. Simmons is the recipient of a grant from the Hardesty Family Foundation to support an ongoing clinical trial of semaglutide in the treatment of AUD. Dr. Holm has no relevant disclosures.

“We have worked on GLP-1 and alcohol since 2012, and observe promising effects,” Holm told this news organization. 

Her team published two studies earlier this year — one in one in Frontiers in Pharmacology and the other in eBioMedicine — demonstrating that semaglutide, in low doses, reduces alcohol intake in male and female rats.

“We have shown that semaglutide binds to the nucleus accumbens — an area of the brain associated with reward. We have also shown that semaglutide alters the dopamine metabolism when alcohol is on board. This provides a tentative mechanism,” Dr. Holm said. 

First Human Data 

The preclinical data fueled interest in testing the value of the GLP-1 agonist in patient populations with addiction.

Dr. Simmons and colleagues have now published what is believed to be the first evidence in humans that semaglutide specifically reduces the symptoms of alcohol use disorder (AUD).

In a report published online on November 27 in The Journal of Clinical Psychiatry, they describe six patients (of whom five are female; mean age, 43 years) who received semaglutide treatment in the course of pharmacotherapy for weight loss.

All six screened positive for AUD on the Alcohol Use Disorders Identification Test (AUDIT), and all six showed significant improvement in their alcohol-related symptoms after starting semaglutide. 

An AUDIT score > 8 is considered positive. The mean AUDIT score at baseline was 14. It fell to 4.5 on average after semaglutide treatment. The mean 9.5-point decrease in AUDIT scores with semaglutide was statistically significant (P < .001). 

The patients were followed up from a few weeks to almost 9 months, and all of them had a reduction in AUD symptoms. At the various follow-up time points, all six patients had AUDIT scores consistent with “low-risk” drinking.

Strong Response at Low Doses 

“There was a very strong response, even at a very low dose,” lead author Jesse Richards, DO, director of obesity medicine and assistant professor of medicine University of Oklahoma School of Community Medicine, Tulsa, said in an interview. 

Three patients were treated with 0.5 mg of semaglutide weekly, two with 0.25 mg weekly, and one with 1 mg weekly. These doses are lower than those currently approved for treatment of type 2 diabetes and obesity. 

Dr. Holm is not surprised by the results in these six patients. “Based on our preclinical data, this outcome is expected. The data are promising and bigger studies needed,” she said.

Simmons is currently leading a randomized placebo-controlled trial to further test the impact of semaglutide on AUD. 

The STAR (Semaglutide Therapy for Alcohol Reduction) study is funded by the Hardesty Family Foundation and Oklahoma State University Center for Health Sciences.

A sister study is also currently underway in Baltimore, funded by the National Institute on Drug Abuse.

Hopefully, these studies will be able to “definitively tell us whether semaglutide is safe and effective for treatment” for AUD, Dr. Simmons said in a statement. 

Despite being a major cause of preventable death worldwide, AUD currently has only three FDA-approved pharmacotherapies. However, there has been limited uptake of these drugs. 

“There remains a significant treatment gap and need for new and novel or perhaps better tolerated or different mechanism treatment options for patients,” Dr. Richards said. 

The preclinical and early clinical data provide a “signal” of a treatment effect for semaglutide in AUD, Dr. Richards said. The randomized controlled trials now underway should be concluding in the next 1-2 years, “at which point we’ll have a much better sense of the safety and efficacy of this drug for AUD,” he said. 

The case series had no specific funding. Dr. Richards is on speakers bureaus for Rhythm Pharmaceuticals and Novo Nordisk and is on an advisory board for Rhythm Pharmaceuticals. Simmons is the recipient of a grant from the Hardesty Family Foundation to support an ongoing clinical trial of semaglutide in the treatment of AUD. Dr. Holm has no relevant disclosures.

The glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide has made headlines as a US Food and Drug Administration (FDA)–approved treatment for type 2 diabetes (Ozempic) and obesity (Wegovy). 

Recently, attention has turned to the possibility that semaglutide may have broader applications, including its potential positive impact on addictive behaviors such as reducing drug craving and alcohol consumption. 

“There is some really interesting preclinical research in rodents and monkeys that shows that GLP-1 agonist molecules, like semaglutide, have the effect of reducing the consumption of not just food, but also alcohol, nicotine, cocaine and amphetamines,” Kyle Simmons, PhD, professor of pharmacology and physiology at Oklahoma State University Center for Health Sciences in Tulsa, said in an interview.

As we begin to find our way in the new world of obesity management, questions continue to surface more quickly than answers. This isn’t surprising, as we are being asked to view obesity as a disease when for decades the general consensus has been that overweight people are simply will power deficient.

Are the new drugs as effective as we are told by the patients and physicians who have had some experience using and prescribing them? Will they continue to be effective in the very long run? Will their safety record hold up over time? And for those of us in pediatrics, what will be their role for children? As a group we tend to be cautious about drugs that haven’t been thoroughly tested in children. How many years will it take before we feel comfortable with obesity drugs? And, of course, we should be asking ourselves the same questions about bariatric surgery.

Fortunately, while the media spotlight has been focused on the treatment arm of our obesity strategy, there are still some folks looking at what has been up to now the discouraging prospects for prevention. The U.S. Preventive Services Task Force (USPSTF) has recently released a draft of its recommendations that includes evidence supporting the effectiveness of “intensive behavioral interventions” (defined as a minimum of 26 hours of counseling). In reviewing data from nearly 60 randomized controlled trials, which included more than 10,000 children, the task force found that when beginning as early as age 6, a package including healthy eating education, physical activity, and behavioral change support could be effective in helping the children achieve healthy weight and an improved quality of life. It should be noted that the USPSTF gave the intervention package only a B grade, which means that the agency found evidence of high certainty of a moderate benefit over an unspecified time period. Certainly, not a ringing endorsement.

While I think we must applaud the diligent efforts of the task force and its commitment to prevention, I fear that the strategy is too little too late. That being said, I am willing to accept the idea that targeting age 6 for intensive counseling may qualify for the better-late-than-never category. The task force acknowledges that procuring the resources given our already understaffed mental health clinics is going to be difficult and expensive. I would add that it will be so costly in time and money as to be unrealistic.

Based on my observations of thousands of children, the scaffolding of habits, diet, and preference for inactivity that underly obesity has already been laid by age 6. Are we prepared to shoulder our already overburdened school systems in an attempt to reconfigure this foundation of an obesogenic lifestyle? An effort on this scale after children have been sent off to first grade is doomed to failure.

A recent review of data reported by the CDC and reviewed in the journal Pediatrics reveals that about 2% of children receiving federal assistance from the WIC program are severely obese. It is probably safe to say that these preschoolers represent just the tip of a very concerning iceberg.

By waiting until age 6, we would increase the risk of further stigmatizing the obese child. What will he tell his peers when he is taken out of school or misses a playdate because he has to meet with his “obesity counselor”?

If we are going to take obesity prevention seriously and spend time and money in counseling, doesn’t it make more sense to invest this effort on the parents and the home situation when the child is still under their influence? We must be prepared to unwrap and employ an “intensive behavioral package” the first time we see evidence that the child’s growth chart is heading in an unhealthy direction.

This won’t always be easy. I can recall seeing a 4-year-old whose weight had risen dramatically from her previous curve in the year since her 3-year checkup. The answer became obvious when I discovered that her grandmother, for whom baking was a passion, had taken over as her daycare provider. Arriving at a solution that kept the family on speaking terms took some tact, but it was one of my rare successes in obesity prevention. And, it worked because of early intervention.

Thank you USPSTF, but 6 years is too late.

As an endocrinologist, I treat many patients who have diabetes, obesity, or both. Antiobesity medications, particularly the class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), are our first support tools when nutrition and physical activity aren’t enough. With the holidays upon us, here are five tips that I often share with my patients who are on GLP-1 RAs and similar medications.

1. Be mindful of fullness cues. 

GLP-1 RAs increase satiety; they help patients feel fuller sooner within a meal and longer in between meals. This means consuming the “usual” at a holiday gathering makes them feel as if they ate too much, and often this will result in more side effects, such as nausea and reflux.

Patient tip: A good rule of thumb is to anticipate feeling full with half of your usual portion. Start with half a plate and reassess your hunger level after finishing.

2. Distinguish between hunger and “food noise.”

Ask your patients, “Do you ever find yourself eating even when you’re not hungry?” Many people eat because of emotions (eg, stress, anxiety, happiness), social situations, or cultural expectations. This type of food consumption is what scientists call “hedonic food intake” and may be driven by the “food noise” that patients describe as persistent thoughts about food in the absence of physiologic hunger. Semaglutide (Ozempic, Wegovy) has been found to reduce cravings, though other research has shown that emotional eating may blunt the effect of GLP-1 RAs.

Patient tip: Recognize when you might be seeking food for reasons other than hunger, and try a different way to address the cue (eg, chat with a friend or family member, go for a walk).

3. Be careful with alcohol.

GLP-1 RAs are being researched as potential treatments for alcohol use disorder. Many patients report less interest in alcohol and a lower tolerance to alcohol when they are taking a GLP-1 RA. Additionally, GLP-1 RAs may be a risk factor for pancreatitis, which can be caused by consuming too much alcohol.

Patient tip: The standard recommendation remains true: If drinking alcohol, limit to one to two servings per day, but also know that reduced intake or interest is normal when taking a GLP-1 RA.

4. Be aware of sickness vs side effects.

With holiday travel and the winter season, it is common for people to catch a cold or a stomach bug. Symptoms of common illnesses might include fatigue, loss of appetite, or diarrhea. These symptoms overlap with side effects of antiobesity medications like semaglutide and tirzepatide.

Patient tip: If you are experiencing constitutional or gastrointestinal symptoms due to illness, speak with your board-certified obesity medicine doctor, who may recommend a temporary medication adjustment to avoid excess side effects.

5. Stay strong against weight stigma.

The holiday season can be a stressful time, especially as patients are reconnecting with people who have not been a part of their health or weight loss journey. Unfortunately, weight bias and weight stigma remain rampant. Many people don’t understand the biology of obesity and refuse to accept the necessity of medical treatment. They may be surrounded by opinions, often louder and less informed.

Patient tip: Remember that obesity is a medical disease. Tell your nosy cousin that it’s a private health matter and that your decisions are your own.

Severe obesity among preschool-age children from low-income families is on the rise in the United States, according to a new analysis of federal data.

An estimated 2% of children ages 2 to 4 years old had severe obesity in 2020, up from 1.8% in 2016, according to the report that appeared Dec. 18 in Pediatrics, a journal published by the American Academy of Pediatrics. 

The increase is “small but significant,” a group of experts not involved in the research wrote in a companion commentary published alongside the research.

The new data put an end to hopes that childhood obesity was on the retreat following a small decrease in rates from 2010 to 2016. Instead, the researchers noted that the new childhood obesity figures reflect those of the general population. In the United States, about 20% of children and teens are obese, and about 42% of adults are obese, according to the CDC.

This latest study looked for severe obesity, which was defined as being well above the 95th percentile for the combined height-weight measure known as body mass index. The figures are important because rates of severe obesity among young children can foreshadow health problems that may occur on a scale to warrant concerns among public health officials, policymakers, and health care professionals.

Compared with children who have moderate obesity, children with severe obesity “are at a greater risk of various health complications, including cardiovascular disease, metabolic syndrome, type 2 diabetes, fatty liver disease, and premature death,” the study authors wrote.

The largest increases from 2016 to 2020 in severe obesity were observed among 4-year-olds and among Hispanic children. When looking at state-level data, Alaska was the only state to report a decline in severe obesity among young children from 2016 to 2020.

The new estimates were drawn from data on children enrolled in the federal Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

“WIC is a federal assistance program that provides healthy foods, nutrition education, health care referrals, and other services to millions of low-income pregnant and postpartum women, as well as infants and children up to age 5, who are at nutritional risk,” the researchers noted.

The new figures indicate 16.6 million children ages 2 to 4 years old have severe obesity. Having severe obesity at these early ages is “nearly irreversible,” the authors of the commentary article noted, adding that little research exists that indicates how to effectively treat obesity before age 6.

“The study underscores the need for ongoing monitoring ... post pandemic of children’s health status,” a news release from the American Academy of Pediatrics stated. “It also further supports the need for children and families from households with lower incomes across the nation to have access to early clinical detection, such as health care screenings and referrals to effective family-based interventions to support healthy growth.”

Severe obesity among preschool-age children from low-income families is on the rise in the United States, according to a new analysis of federal data.

An estimated 2% of children ages 2 to 4 years old had severe obesity in 2020, up from 1.8% in 2016, according to the report that appeared Dec. 18 in Pediatrics, a journal published by the American Academy of Pediatrics. 

The increase is “small but significant,” a group of experts not involved in the research wrote in a companion commentary published alongside the research.

The new data put an end to hopes that childhood obesity was on the retreat following a small decrease in rates from 2010 to 2016. Instead, the researchers noted that the new childhood obesity figures reflect those of the general population. In the United States, about 20% of children and teens are obese, and about 42% of adults are obese, according to the CDC.

This latest study looked for severe obesity, which was defined as being well above the 95th percentile for the combined height-weight measure known as body mass index. The figures are important because rates of severe obesity among young children can foreshadow health problems that may occur on a scale to warrant concerns among public health officials, policymakers, and health care professionals.

Compared with children who have moderate obesity, children with severe obesity “are at a greater risk of various health complications, including cardiovascular disease, metabolic syndrome, type 2 diabetes, fatty liver disease, and premature death,” the study authors wrote.

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are associated with a reduced risk for colorectal cancer (CRC) in patients with type 2 diabetes, with and without overweight or obesity, according to a new analysis.

In particular, GLP-1 RAs were associated with decreased risk compared with other antidiabetic treatments, including insulin, metformin, sodium-glucose cotransporter 2 (SGLT2) inhibitors, sulfonylureas, and thiazolidinediones.

More profound effects were seen in patients with overweight or obesity, “suggesting a potential protective effect against CRC partially mediated by weight loss and other mechanisms related to weight loss,” Lindsey Wang, an undergraduate student at Case Western Reserve University, Cleveland, Ohio, and colleagues wrote in JAMA Oncology.
 

Testing Treatments

GLP-1 RAs, usually given by injection, are approved by the US Food and Drug Administration to treat type 2 diabetes. They can lower blood sugar levels, improve insulin sensitivity, and help patients manage their weight.

Diabetes, overweight, and obesity are known risk factors for CRC and make prognosis worse. Ms. Wang and colleagues hypothesized that GLP-1 RAs might reduce CRC risk compared with other antidiabetics, including metformin and insulin, which have also been shown to reduce CRC risk.

Using a national database of more than 101 million electronic health records, Ms. Wang and colleagues conducted a population-based study of more than 1.2 million patients who had medical encounters for type 2 diabetes and were subsequently prescribed antidiabetic medications between 2005 and 2019. The patients had no prior antidiabetic medication use nor CRC diagnosis.

The researchers analyzed the effects of GLP-1 RAs on CRC incidence compared with the other prescribed antidiabetic drugs, matching for demographics, adverse socioeconomic determinants of health, preexisting medical conditions, family and personal history of cancers and colonic polyps, lifestyle factors, and procedures such as colonoscopy.

During a 15-year follow-up, GLP-1 RAs were associated with decreased risk for CRC compared with insulin (hazard ratio [HR], 0.56), metformin (HR, 0.75), SGLT2 inhibitors (HR, 0.77), sulfonylureas (HR, 0.82), and thiazolidinediones (HR, 0.82) in the overall study population.

For instance, among 22,572 patients who took insulin, 167 cases of CRC occurred, compared with 94 cases among the matched GLP-1 RA cohort. Among 18,518 patients who took metformin, 153 cases of CRC occurred compared with 96 cases among the matched GLP-1 RA cohort.

GLP-1 RAs also were associated with lower but not statistically significant risk than alpha-glucosidase inhibitors (HR, 0.59) and dipeptidyl-peptidase-4 (DPP-4) inhibitors (HR, 0.93).

In patients with overweight or obesity, GLP-1 RAs were associated with a lower risk for CRC than most of the other antidiabetics, including insulin (HR, 0.5), metformin (HR, 0.58), SGLT2 inhibitors (HR, 0.68), sulfonylureas (HR, 0.63), thiazolidinediones (HR, 0.73), and DPP-4 inhibitors (HR, 0.77).

Consistent findings were observed in women and men.

“Our results clearly demonstrate that GLP-1 RAs are significantly more effective than popular antidiabetic drugs, such as metformin or insulin, at preventing the development of CRC,” said Nathan Berger, MD, co-lead researcher, professor of experimental medicine, and member of the Case Comprehensive Cancer Center.
 

Targets for Future Research

Study limitations include potential unmeasured or uncontrolled confounders, self-selection, reverse causality, and other biases involved in observational studies, the research team noted.

Further research is warranted to investigate the effects in patients with prior antidiabetic treatments, underlying mechanisms, potential variation in effects among different GLP-1 RAs, and the potential of GLP-1 RAs to reduce the risks for other obesity-associated cancers, the researchers wrote.

“To our knowledge, this is the first indication this popular weight loss and antidiabetic class of drugs reduces incidence of CRC, relative to other antidiabetic agents,” said Rong Xu, PhD, co-lead researcher, professor of medicine, and member of the Case Comprehensive Cancer Center.

The study was supported by the National Cancer Institute Case Comprehensive Cancer Center, American Cancer Society, Landon Foundation-American Association for Cancer Research, National Institutes of Health Director’s New Innovator Award Program, National Institute on Aging, and National Institute on Alcohol Abuse and Alcoholism. Several authors reported grants from the National Institutes of Health during the conduct of the study.
