ADA issues new screening, obesity management recommendations
for 2024.
“The Standards of Care are essentially the global guidelines for the care of individuals with diabetes and those at risk,” ADA chief scientific and medical officer Robert Gabbay, MD, PhD, said during a briefing announcing the new Standards.
The document was developed via a scientific literature review by the ADA’s Professional Practice Committee. The panel comprises 21 professionals, including physicians from many specialties, nurse practitioners, certified diabetes care and education specialists, dietitians, and pharmacists. The chair is Nuha A. El Sayed, MD, ADA’s senior vice president of healthcare improvement.
Specific sections of the 2024 document have been endorsed by the American College of Cardiology, the American Society of Bone and Mineral Research, and the Obesity Society. It was published on December 11, 2023, as a supplement in Diabetes Care.
An introductory section summarizing the changes for 2024 spans six pages. Those addressed during the briefing included the following:
Heart Failure Screening: Two new recommendations have been added to include screening of adults with diabetes for asymptomatic heart failure by measuring natriuretic peptide levels to facilitate the prevention or progression to symptomatic stages of heart failure.
“This is a really important and exciting area. We know that people with type 2 diabetes in particular are at high risk for heart failure,” Dr. Gabbay said, adding that these recommendations “are to really more aggressively screen those at high risk for heart failure with a simple blood test and, based on those values, then be able to move on to further evaluation and echocardiography, for example. The recommendations are really to screen a broad number of individuals with type 2 diabetes because many are at risk, [particularly] those without symptoms.”
PAD Screening: A new strong recommendation is to screen for PAD with ankle-brachial index testing in asymptomatic people with diabetes who are aged ≥ 50 years and have microvascular disease in any location, foot complications, or any end-organ damage from diabetes. The document also advises consideration of PAD screening for all individuals who have had diabetes for ≥ 10 years.
Dr. Gabbay commented, “We know that amputation rates are rising, unlike many other complications. We know that there are incredible health disparities. Blacks are two to four times more likely than Whites to have an amputation.”
Dr. El Sayed added, “Many patients don’t show the common symptoms of peripheral arterial disease. Screening is the most important way to find out if they have it or not because it can be a very devastating disease.”
Type 1 Diabetes Screening: This involves several new recommendations, including a framework for investigating suspected type 1 diabetes in newly diagnosed adults using islet autoantibody tests and diagnostic criteria for preclinical stages based on the recent approval of teplizumab for delaying the onset of type 1 diabetes.
“Screening and capturing disease earlier so that we can intervene is really an important consideration here. That includes screening for type 1 diabetes and thinking about therapeutic options to delay the development of frank type 1 diabetes,” Dr. Gabbay said.
Screening first-degree relatives of people with type 1 diabetes is a high priority because they’re at an elevated risk, he added.
Obesity Management: New recommendations here include the use of anthropomorphic measurements beyond body mass index to include waist circumference and waist:hip ratio and individual assessment of body fat mass and distribution.
Individualization of obesity management including behavioral, pharmacologic, and surgical approaches is encouraged. The use of a glucagon-like peptide-1 (GLP-1) receptor agonist or a dual glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist with greater weight loss efficacy is preferred for obesity management in people with diabetes.
“Obesity management is one of the biggest changes over this last year,” Dr. Gabbay commented.
Other New Recommendations: Among the many other revisions in the 2024 document are new recommendations about regular evaluation and treatment for bone health, assessment of disability and guidance for referral, and alignment of guidance for liver disease screening and management with those of other professional societies. Regarding the last item, Dr. Gabbay noted, “I don’t think it’s gotten the attention it deserves. Diabetes and obesity are becoming the leading causes of liver disease.”
Clinicians can also download the Standards of Care app on their smartphones. “That can be really helpful when questions come up since you can’t remember everything in there. Here you can look it up in a matter of seconds,” Dr. Gabbay said.
Dr. El Sayed added that asking patients about their priorities is also important. “If they aren’t brought up during the visit, it’s unlikely to be as fruitful as it should be.”
Dr. El Sayed has no disclosures. Dr. Gabbay serves as a consultant and/or advisor for HealthReveal, Lark Technologies, Onduo, StartUp Health, Sweetech, and Vida Health.

New COVID variant JN.1 could disrupt holiday plans
No one planning holiday gatherings or travel wants to hear this, but the rise of a new COVID-19 variant, JN.1, is concerning experts, who say it may threaten those good times.
The good news is recent research suggests the 2023-2024 COVID-19 vaccine appears to work against this newest variant. But so few people have gotten the latest vaccine — less than 16% of U.S. adults — that some experts suggest it’s time for the CDC to urge the public who haven’t it to do so now, so the antibodies can kick in before the festivities.
“A significant wave [of JN.1] has started here and could be blunted with a high booster rate and mitigation measures,” said Eric Topol, MD, professor and executive vice president of Scripps Research in La Jolla, CA, and editor-in-chief of Medscape, a sister site of this news organization.
COVID metrics, meanwhile, have started to climb again. Nearly 10,000 people were hospitalized for COVID in the U.S. for the week ending Nov. 25, the CDC said, a 10% increase over the previous week.
Who’s Who in the Family Tree
JN.1, an Omicron subvariant, was first detected in the U.S. in September and is termed “a notable descendent lineage” of Omicron subvariant BA.2.86 by the World Health Organization. When BA.2.86, also known as Pirola, was first identified in August, it appeared very different from other variants, the CDC said. That triggered concerns it might be more infectious than previous ones, even for people with immunity from vaccination and previous infections.
“JN.1 is Pirola’s kid,” said Rajendram Rajnarayanan, PhD, assistant dean of research and associate professor at the New York Institute of Technology at Arkansas State University, who maintains a COVID-19 variant database. The variant BA.2.86 and offspring are worrisome due to the mutations, he said.
How Widespread Is JN.1?
As of Nov. 27, the CDC says, BA.2.86 is projected to comprise 5%-15% of circulating variants in the U.S. “The expected public health risk of this variant, including its offshoot JN.1, is low,” the agency said.
Currently, JN.1 is reported more often in Europe, Dr. Rajnarayanan said, but some countries have better reporting data than others. “It has probably spread to every country tracking COVID,’’ he said, due to the mutations in the spike protein that make it easier for it to bind and infect.
Wastewater data suggest the variant’s rise is helping to fuel a wave, Dr. Topol said.
Vaccine Effectiveness Against JN.1, Other New Variants
The new XBB.1.5 monovalent vaccine, protects against XBB.1.5, another Omicron subvariant, but also JN.1 and other “emergent” viruses, a team of researchers reported Nov. 26 in a study on bioRxiv that has not yet been certified by peer review.
The updated vaccine, when given to uninfected people, boosted antibodies about 27-fold against XBB.1.5 and about 13- to 27-fold against JN.1 and other emergent viruses, the researchers reported.
While even primary doses of the COVID vaccine will likely help protect against the new JN.1 subvariant, “if you got the XBB.1.5 booster, it is going to be protecting you better against this new variant,” Dr. Rajnarayanan said.
2023-2024 Vaccine Uptake Low
In November, the CDC posted the first detailed estimates of who did. As of Nov. 18, less than 16% of U.S. adults had, with nearly 15% saying they planned to get it.
Coverage among children is lower, with just 6.3% of children up to date on the newest vaccine and 19% of parents saying they planned to get the 2023-2024 vaccine for their children.
Predictions, Mitigation
While some experts say a peak due to JN.1 is expected in the weeks ahead, Dr. Topol said it’s impossible to predict exactly how JN.1 will play out.
“It’s not going to be a repeat of November 2021,” when Omicron surfaced, Dr. Rajnarayanan predicted. Within 4 weeks of the World Health Organization declaring Omicron as a virus of concern, it spread around the world.
Mitigation measures can help, Dr. Rajnarayanan said. He suggested:
Get the new vaccine, and especially encourage vulnerable family and friends to do so.
If you are gathering inside for holiday festivities, improve circulation in the house, if possible.
Wear masks in airports and on planes and other public transportation.

T2D: Real benefits of new oral antidiabetic drugs
Cardiovascular disease is the most common cause of death in people living with type 2 diabetes (T2D). It is true that patient prognoses have improved with the use of metformin and by addressing cardiovascular risk factors. But the new oral antidiabetic drugs, SGLT2 (sodium glucose cotransporter-2) inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1Ra) offer fresh therapeutic approaches.
A cohort of more than 2 million patients with T2D
What about in the real world, far away from the ideal conditions of randomized trials? Could combining SGLT2 inhibitors with GLP-1R agonists be even more effective?
These are the questions answered by a large retrospective cohort study in which 2.2 million patients with T2D receiving insulin were initially enrolled and monitored at 85 specialist centers spread throughout three countries (Denmark, the United Kingdom, and the United States).
Three groups were formed from this cohort according to whether they received monotherapy or combination treatments: SGLT2i (n = 143,600), GLP-1Ra (n = 186,841), and SGLT2i + GLP-1Ra (n = 108,5040). A control group received none of these treatments.
Propensity score matching took into account the following relevant variables: age, sex, ischemic heart disease, hypertension, chronic kidney disease, heart failure, and glycated hemoglobin. The data was analyzed using the Cox’s proportional hazards model, with follow-up at 5 years.
Real-world benefits – Even better when combined
The inter-group comparison suggests that oral antidiabetic agents are effective when taking into account three major events:
All-cause mortality: SGLT2i (hazard ratio, 0.49; confidence interval 95% 0.48-0.50); GLP-1Ra (HR, 0.47; CI 95% 0.46-0.48); SGLT2i + GLP-1Ra (HR, 0.25; CI 95% 0.24-0.26).
Admissions rate: respectively HR: 0.73 (0.72-0.74); 0.69 (0.68-0.69); 0.60 (0.59-0.61).
Myocardial infarction rate: respectively HR: 0.75 (0.72-0.78); 0.70 (0.68-0.73); 0.63 (0.60-0.66).
A complementary sub-analysis also revealed a more significant reduction in all-cause mortality in the event of exposure to the combination of two antidiabetic drugs versus SGLT2i alone (HR, 0.53 [0.50-0.55]) and GLP-1Ra as monotherapy (HR, 0.56 [0.54-0.59]).
This real-world retrospective cohort study involves a large sample size: more than 400,000 patients with T2D treated with new oral antidiabetic drugs and as many control patients. It suggests that SGLT2 inhibitors and GLP-1R agonists have a significant effect on overall mortality, as well as on the risk of myocardial infarction and the admissions rate. Yes, it is retrospective, but its findings are in line with those from the most recent and conclusive randomized trials that suggest a cardio- and nephroprotective effect, at least with regard to SGLT2 inhibitors.

Yes, it is retrospective, but its findings are in line with those from the most recent and conclusive randomized trials that suggest a cardio- and nephroprotective effect, at least with regard to SGLT2 inhibitors.

Cardiovascular disease is the most common cause of death in people living with type 2 diabetes (T2D). It is true that patient prognoses have improved with the use of metformin and by addressing cardiovascular risk factors. But the new oral antidiabetic drugs, SGLT2 (sodium glucose cotransporter-2) inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1Ra) offer fresh therapeutic approaches.
A cohort of more than 2 million patients with T2D
What about in the real world, far away from the ideal conditions of randomized trials? Could combining SGLT2 inhibitors with GLP-1R agonists be even more effective?
These are the questions answered by a large retrospective cohort study in which 2.2 million patients with T2D receiving insulin were initially enrolled and monitored at 85 specialist centers spread throughout three countries (Denmark, the United Kingdom, and the United States).
Three groups were formed from this cohort according to whether they received monotherapy or combination treatments: SGLT2i (n = 143,600), GLP-1Ra (n = 186,841), and SGLT2i + GLP-1Ra (n = 108,5040). A control group received none of these treatments.
Propensity score matching took into account the following relevant variables: age, sex, ischemic heart disease, hypertension, chronic kidney disease, heart failure, and glycated hemoglobin. The data was analyzed using the Cox’s proportional hazards model, with follow-up at 5 years.
Real-world benefits – Even better when combined
The inter-group comparison suggests that oral antidiabetic agents are effective when taking into account three major events:
All-cause mortality: SGLT2i (hazard ratio, 0.49; confidence interval 95% 0.48-0.50); GLP-1Ra (HR, 0.47; CI 95% 0.46-0.48); SGLT2i + GLP-1Ra (HR, 0.25; CI 95% 0.24-0.26).
Admissions rate: respectively HR: 0.73 (0.72-0.74); 0.69 (0.68-0.69); 0.60 (0.59-0.61).
Myocardial infarction rate: respectively HR: 0.75 (0.72-0.78); 0.70 (0.68-0.73); 0.63 (0.60-0.66).
A complementary sub-analysis also revealed a more significant reduction in all-cause mortality in the event of exposure to the combination of two antidiabetic drugs versus SGLT2i alone (HR, 0.53 [0.50-0.55]) and GLP-1Ra as monotherapy (HR, 0.56 [0.54-0.59]).
This real-world retrospective cohort study involves a large sample size: more than 400,000 patients with T2D treated with new oral antidiabetic drugs and as many control patients.

Blood test could predict future disability in MS
a new study suggests.
Rising NfL levels are a known indicator of neuroaxonal injury and correlate with MS disease activity. Levels rise in the presence of an MS relapse or MRI activity and fall following treatment with disease-modifying therapies. But the link between NfL levels and worsening disability was less understood.
This new analysis of NfL in two large MS cohorts found that elevated levels of the neuronal protein at baseline were associated with large increases in future disability risk, even in patients with no clinical relapse.
“This rising of NfL up to 2 years before signs of disability worsening represents the window when interventions may prevent worsening,” lead investigator Ahmed Abdelhak, MD, department of neurology, University of California, San Francisco, said in a press release.
The findings were published online in JAMA Neurology.
Early warning system?
The study included data on 1,899 patients with nearly 13,000 patient visits from two observational, long-term, real-world cohorts: the U.S.-based Expression, Proteomics, Imaging, Clinical (EPIC) study (n = 609 patients), and the Swiss Multiple Sclerosis Cohort trial (SMSC; n = 1,290 patients).
Investigators analyzed longitudinal serum NfL measurements in conjunction with clinical disability worsening, defined as 6 months or more of increased impairment as measured by the Expanded Disability Status Scale.
Researchers also assessed the temporal association between NfL measurements and the risk of increased disability and distinguished between disability with and without relapse.
Worsening disability was reported in 227 patients in the EPIC group and 435 in the SMSC trial.
Elevated NfL at baseline was associated with a 70% higher risk for worsening disability with relapse about 11 months later in the SMSC study (hazard ratio, 1.70; P = .02). In the EPIC trial, there was trend toward a 91% higher risk for worsening disability with relapse at 12.6 months, although the findings did not meet statistical significance (HR, 1.91; P = .07).
The risk of future disability progression independent of clinical relapse was 40% higher in those with high NfL at baseline in the EPIC study 12 months after baseline (HR, 1.40; P = .02) and 49% higher in the SMSC trial 21 months later (HR, 1.49; P < .001).
The early elevation of NfL levels suggests a slower degradation of nerve cells and could be a possible early warning system of future progression of disability, allowing time for interventions that could slow or even halt further disability.
“Monitoring NfL levels might be able to detect disease activity with higher sensitivity than clinical exam or conventional imaging,” senior author Jens Kuhle, MD, PhD, leader of the Swiss cohort and head of the Multiple Sclerosis Center at University Hospital and University of Basel, said in a statement.
Challenges for clinicians
Commenting on the findings, Robert Fox, MD, staff neurologist at the Mellen Center for MS and vice chair for research, Neurological Institute, Cleveland Clinic, said that, while there is a clinical test to measure NfL levels, incorporating that test into standard of care isn’t straightforward.
“The challenge for the practicing clinician is to translate these population-level studies to individual patient management decisions,” said Dr. Fox, who was not a part of the study.
“The published prediction curves corrected for age, sex, disease course, disease-modifying treatment, relapse within the past 90 days, and current disability status, the combination of which makes it rather challenging to calculate and interpret adjusted z score NfL levels in routine practice and then use it in clinical decision-making.”
The investigators said the study underscores the importance of NfL as an MS biomarker and “points to the existence of different windows of dynamic central nervous system pathology” that precedes worsening disability with or without relapse. But there may be a simpler explanation, Dr. Fox suggested.
“We know MRI activity occurs 5-10 times more frequently than relapses, and we know that MRI activity is associated with both NfL increases and future disability progression,” Dr. Fox said. “It is quite likely that the elevations in NfL seen here are reflective of new MRI disease activity, which frequently is seen without symptoms of an MS relapse,” he said
The study was funded by the Westridge Foundation, F. Hoffmann–La Roche, the Fishman Family, the Swiss National Research Foundation, the National Institutes of Health/National Institute of Neurological Disorders and Stroke, and the Valhalla Foundation. Dr. Abdelhak reported receiving grants from the German Multiple Sclerosis Society and the Weill Institute for Neurosciences outside the submitted work. Dr. Kuhle has received grants from Swiss MS Society, the Swiss National Research Foundation, the Progressive MS Alliance, Biogen, Merck, Celgene, Bristol-Myers Squibb, Novartis, Octave Bioscience, Roche, Sanofi, Alnylam, Bayer, Immunic, Quanterix, Neurogenesis, Stata DX, and the University of Basel outside the submitted work. Dr. Fox reported receiving consulting fees from Siemens and Roche.

Semaglutide prescribing surged in the past year
Among more than 350,000 prescribers in the nationwide DrFirst network between December 2022 and June 2023, prescriptions for the weight loss formulation Wegovy rose sixfold while those for Ozempic, the lower-dose version for treating type 2 diabetes, increased by 65%.
Before December 2022, prescribing for both semaglutide drug formulations had been relatively flat. Ozempic was approved in the United States for treating type 2 diabetes in 2017, and Wegovy for weight loss in 2021. Prescribing of oral type 2 diabetes drugs also rose during the study period but to a lesser degree.
General and family practice providers were the most frequent semaglutide providers, accounting for 30% of the total, followed by internists at 15%, endocrinologists at 4%, ob.gyns. at 2%, and pediatricians at 1%. Other specialists writing less than 1% of the prescriptions included cardiologists, emergency medicine physicians, hospitalists, psychiatrists, and surgeons.
“What I think is interesting is that in a relatively short period of time, primary care providers got comfortable with writing [prescriptions] for a drug that’s relatively new ... That isn’t always the case ... To me, it’s actually pretty telling that within a year or year and a half, the primary care field got very comfortable writing [prescriptions] for these [glucagon-like peptide 1 receptor agonists],” DrFirst chief medical officer Colin Banas, MD, said in an interview.
Asked to comment, S. Sethu K. Reddy, MD, president of the American Association of Clinical Endocrinologists, noted, “It is to be expected when there is an agent that not only lowers blood sugar levels but also may result in weight loss. These medications are packaged conveniently for a primary care physician to prescribe. There is enough awareness amongst the public in that the patients themselves often ask their physician about the medication.”
Moreover, Dr. Reddy noted, “there is clinical evidence that these medications not only improve diabetes control but also reduce the risk of cardiovascular events. The lack of cardiovascular safety data was a missing piece of the puzzle in the past. So, currently, if someone has type 2 diabetes and is at greater risk of cardiovascular disease, there is little controversy for the patient to receive GLP-1 analogs.”
Are patients actually getting the prescribed medications?
However, Sharon W. Lahiri, MD, of Wayne State University School of Medicine and Henry Ford Hospital, Detroit, pointed out that prescription data don’t equate to actual drug use. “It depends what type of insurance a person has. ... We write prescriptions on a daily basis for semaglutide. At least five or more come into our inbox every day saying it’s denied.”
Earlier this year, Dr. Lahiri co-authored results from a survey of 125 health care providers between February 9 and March 14, 2022, seeking to identify factors influencing medication choices and barriers to prescribing both GLP-1 agonists and sodium-glucose cotransporter 2 inhibitors. High cost and the need for prior authorizations were reported as the main barriers to prescribing drugs in these two classes, along with a lack of experience among some specialists.
Dr. Lahiri told this news organization that many insurers don’t cover Wegovy at all, or they mandate stepped-care paradigms in which the patient must enroll in behavior modification programs for a period of time or first try older, less expensive weight loss drugs such as phentermine, topiramate, or orlistat before they authorize coverage for Wegovy or even for the older weight-loss GLP-1 agonist drug Saxenda. “And then, they require you to document why the prior drugs didn’t work or couldn’t be tolerated.”
Moreover, Wegovy coverage is often time-limited, varying anywhere from 3 months to 2 years, and some insurers require a visit where the patient must have lost at least 5% of their body weight for coverage to continue.
Dr. Lahiri said recently she’s also encountered such “step” requirements when she’s tried to prescribe the “twincretin” Mounjaro for treating type 2 diabetes, where insurers will require trials of other GLP-1 agonists first. “So, it’s very complicated. I would say the barriers are definitely worse now. I don’t think the number of written prescriptions reflects that at all.”
Indeed, Dr. Banas noted, “more patients are going to pay out of pocket for Wegovy than for Ozempic if they have a diabetes indication.” And he added, “In my clinical observation, insurance coverage for obesity medication appears to be holding steady. I haven’t seen a massive increase in these drugs being covered for obesity per se, but I definitely see more coverage for diabetes use cases.”
The study was funded by DrFirst. Dr. Banas is an employee of DrFirst. Dr. Reddy and Dr. Lahiri have no disclosures.

Nirmatrelvir-ritonavir ineffective at reducing most post-COVID conditions
TOPLINE:
Thromboembolic events are the exception.
METHODOLOGY:
- A retrospective study of 9,593 veterans older than 65 years examined the impact of nirmatrelvir-ritonavir in comparison with no treatment on post–COVID-19 conditions (PCCs).
- Researchers coded 31 conditions, including those that fell into cardiac, pulmonary, renal, thromboembolic, gastrointestinal, neurologic, mental health, musculoskeletal, and endocrine categories.
- The incidence of PCCs was analyzed 31-180 days after treatment.
TAKEAWAY:
- The combined incidence of venous thromboembolism and pulmonary embolism was reduced among patients given nirmatrelvir-ritonavir.
- No statistically significant reduction of other conditions was found.
- Results differ from the conclusions of a smaller study that found that the incidence of 10 of 13 PCCs was lower.
IN PRACTICE:
“Our results suggest that considerations about PCCs may not be an important factor in COVID-19 treatment decisions,” the authors write.
SOURCE:
The study was funded by the Department of Veterans Affairs and was published online in Annals of Internal Medicine. George Ioannou, MD, director of hepatology at the VA Puget Sound Health Care System in Seattle, led the study.
LIMITATIONS:
A large number of outcomes were observed, so it’s possible that the association between treatment with nirmatrelvir-ritonavir and reduced incidence of thromboembolic events occurred by chance.
Data on COVID-19 treatments and PCCs may be incomplete. The long-term effects of PCCs may not have been fully captured by the ICD-10, which was used for diagnosis codes.
Electronic health records did not accurately capture the symptom burden or the date symptoms began. Patients in the treatment arm may have had more symptoms than matched control persons who were not treated.

TOPLINE:
Thromboembolic events are the exception.
METHODOLOGY:
- A retrospective study of 9,593 veterans older than 65 years examined the impact of nirmatrelvir-ritonavir in comparison with no treatment on post–COVID-19 conditions (PCCs).
- Researchers coded 31 conditions, including those that fell into cardiac, pulmonary, renal, thromboembolic, gastrointestinal, neurologic, mental health, musculoskeletal, and endocrine categories.
- The incidence of PCCs was analyzed 31-180 days after treatment.
TAKEAWAY:
- The combined incidence of venous thromboembolism and pulmonary embolism was reduced among patients given nirmatrelvir-ritonavir.
- No statistically significant reduction of other conditions was found.
- Results differ from the conclusions of a smaller study that found that the incidence of 10 of 13 PCCs was lower.
IN PRACTICE:
“Our results suggest that considerations about PCCs may not be an important factor in COVID-19 treatment decisions,” the authors write.

Antidepressants ‘don’t blunt’ semaglutide and weight loss
in a post hoc analysis of the Semaglutide Treatment Effect in People with Obesity (STEP) program.
Adverse events, including psychiatric events, were slightly more usual in the patients on antidepressants, Robert Kushner, MD, noted, in an oral session at the annual meeting of the Obesity Society.
“It is very common that patients who present for weight management are taking antidepressants for various reasons, including depression, anxiety, insomnia, or chronic pain,”Dr. Kushner, from Northwestern University in Chicago, said in an email. “We wanted to see if these participants responded differently to semaglutide, compared to those not on antidepressants.”
“We found that antidepressants do not blunt the effect of semaglutide for weight loss,” he said. “However, there is a slight increase in reported adverse effects.”
“Semaglutide 2.4 mg provides an effective treatment option for weight management, regardless of antidepressant use at baseline,” Dr. Kushner summarized. “Clinicians should be assured that we can use semaglutide in this population of patients.”
Jack Yanovski, MD, PhD, said this was a “great presentation,” noting that “it’s really important that we understand what goes on in patients with depression.”
“Of course, all these trials still had rules that prevent the folks with the most severe depressive symptoms or past suicidality to participate,” added Dr. Yanovski, chief of the Growth and Obesity Section, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Rockville, Md. “We need specific trials to know exactly how well we do.”
Dr. Kushner agreed, but also noted that, ever since some earlier antidepressants were associated with risk for suicidal ideation and death, strict guidelines were put in place that exclude certain patients from participating in clinical trials.
Dr. Yanovski suggested that now that the drugs are approved, it would be possible to study this, and the information would be important for clinicians.
Dr. Kushner said he hopes that such studies are forthcoming. In the meantime, “data like this will add some support and understanding,” he suggested.
36,000 Patients with obesity, 500 on antidepressants
Many people living with obesity report taking antidepressants for depression, anxiety, chronic pain, obsessive-compulsive disorder, sleep disturbance, neuropathy, panic disorder, or posttraumatic stress disorder, Dr. Kushner noted.
However, some of these medications can cause weight gain, and little is known about treatment outcomes for people with obesity who are on antidepressants, since most weight-loss studies exclude people with active major depressive disorder.
The researchers analyzed data from 1,961 patients in STEP 1 and 807 patients in STEP 2 as well as 611 patients in STEP 3 and 304 patients in STEP 5 – 3,683 participants in total, of which 539 were on antidepressants at baseline.
The patients were randomly assigned to 2.4 mg semaglutide vs. placebo plus a lifestyle intervention (STEP 1, 2, and 5) or intensive behavioral therapy (STEP 3 only), for 68 weeks, except STEP 5, which was 104 weeks.
Patients were included if they were aged 18 or older with a body mass index ≥30 kg/m2, or ≥27 kg/m2 with more than one weight-related complication (STEP 1, 3, and 5) or BMI ≥27 kg/m2 with type 2 diabetes (STEP 2 only), and at least one self-reported unsuccessful effort to lose weight by diet.
They were excluded if they had active major depressive disorder within 2 years prior to screening (or other severe psychiatric disorders such as schizophrenia or bipolar disorder) or a Patient Health Questionnaire-9 score of 15 or higher (indicating moderately severe or severe depression), or suicide ideation (type 4 or 5 on the Columbia Suicide Severity Rating Scale) or suicide behavior, within 30 days of screening.
From baseline to week 68, patients on semaglutide (with/without baseline antidepressant use) had a significantly greater change in weight vs. patients on placebo (with/without baseline antidepressant use), respectively:
- STEP 1: –15.7% / –14.7% vs. –0.2% / –2.8%
- STEP 2: –10.7% / –9.5% vs. –3.3% / –3.4%
- STEP 3: –16.2% / –15.9% vs. –5.0% / –5.9%
- STEP 5: –19.0% / –14.1% vs. +1.6% / – 4.0%.
The proportion of reported adverse events was generally slightly greater in patients receiving semaglutide (with/without baseline antidepressant use) than those on placebo (with/without baseline antidepressant use), respectively:
- STEP 1: 97.7% vs 88.6% and 92.9% vs. 86%
- STEP 2: 97.6% vs 86.5% and 88.6% vs. 77.2%
- STEP 3: 97.6% vs 95.3% and 100% vs. 95.8%
- STEP 5: 100% vs 94.8% and 95.5% vs. 89.2%.
Gastrointestinal adverse events were more frequently reported in the semaglutide group and in patients on antidepressants at baseline. The proportion of patients with psychiatric adverse events was greater in participants on antidepressants at baseline. There were no differences in suicidal ideation/behavior in patients with/without antidepressant use at baseline.
The STEP trials were funded by Novo Nordisk. Dr. Kushner discloses that he served as a consultant for Novo Nordisk, WeightWatchers, Eli Lilly, and Pfizer, and received a research grant from Epitomee.

Taking a new obesity drug and birth control pills? Be careful
For women who are obese, daily life is wrought with landmines. Whether it’s the challenges of air travel because plane seats are too small, the need to shield themselves from the world’s discriminating eyes, or the great lengths many will go to achieve better health and the promise of longevity, navigating life as an obese person requires a thick skin.
So, it’s no wonder so many are willing to pay more than $1,000 a month out of pocket to get their hands on drugs like semaglutide (Ozempic and Wegovy) or tirzepatide (Mounjaro). The benefits of these drugs, which are part of a new class called glucagonlike peptide–1 (GLP-1) receptor agonists, include significant and rapid weight loss, blood sugar control, and improved life quality; they are unprecedented in a setting where surgery has long been considered the most effective long-term option.
On the flip side, the desire for rapid weight loss and better blood sugar control also comes with an unexpected cost. , making an unintended pregnancy more likely.
Neel Shah, MD, an endocrinologist and associate professor at the University of Texas Health Science Center at Houston, said he has had several patients become pregnant without intending to.
“It was when Mounjaro came out on the market when we started using it,” he said of the drug the Food and Drug Administration approved for type 2 diabetes in 2022. “It [the warning] was in the product insert, but clinically speaking, I don’t know if it was at the top of providers’ minds when they were prescribing Mounjaro.”
When asked if he believed that we were going to be seeing a significant increase in so-called Mounjaro babies, Dr. Shah was sure in his response.
“Absolutely. We will because the sheer volume [of patients] will increase,” he said.
It’s all in the gut
One of the ways that drugs like Mounjaro work is by delaying the time that it takes for food to move from the stomach to the small intestine. Although data are still evolving, it is believed that this process – delayed gastric emptying – may affect the absorption of birth control pills.
Dr. Shah said another theory is that vomiting, which is a common side effect of these types of drugs, also affects the pills’ ability to prevent pregnancy.
And “there’s a prolonged period of ramping up the dose because of the GI side effects,” said Pinar Kodaman, MD, PhD, a reproductive endocrinologist and assistant professor of gynecology at Yale University in New Haven, Conn.
“Initially, at the lowest dose, there may not be a lot of potential effect on absorption and gastric emptying. But as the dose goes up, it becomes more common, and it can cause diarrhea, which is another condition that can affect the absorption of any medication,” she said.
Unanticipated outcomes, extra prevention
Roughly 42% of women in the United States are obese, 40% of whom are between the ages of 20 and 39. Although these new drugs can improve fertility outcomes for women who are obese (especially those with polycystic ovary syndrome, or PCOS), only one – Mounjaro – currently carries a warning about birth control pill effectiveness on its label. Unfortunately, it appears that some doctors are unaware or not counseling patients about this risk, and the data are unclear about whether other drugs in this class, like Ozempic and Wegovy, have the same risks.
“To date, it hasn’t been a typical thing that we counsel about,” said Dr. Kodaman. “It’s all fairly new, but when we have patients on birth control pills, we do review other medications that they are on because some can affect efficacy, and it’s something to keep in mind.”
It’s also unclear if other forms of birth control – for example, birth control patches that deliver through the skin – might carry similar pregnancy risks. Dr. Shah said some of his patients who became pregnant without intending to were using these patches. This raises even more questions, since they deliver drugs through the skin directly into the bloodstream and not through the GI system.
What can women do to help ensure that they don’t become pregnant while using these drugs?
“I really think that if patients want to protect themselves from an unplanned pregnancy, that as soon as they start the GLP receptor agonists, it wouldn’t be a bad idea to use condoms, because the onset of action is pretty quick,” said Dr. Kodaman, noting also that “at the lowest dose there may not be a lot of potential effect on gastric emptying. But as the dose goes up, it becomes much more common or can cause diarrhea.”
Dr. Shah said that in his practice he’s “been telling patients to add barrier contraception” 4 weeks before they start their first dose “and at any dose adjustment.”
Zoobia Chaudhry, an obesity medicine doctor and assistant professor of medicine at Johns Hopkins University in Baltimore, recommends that “patients just make sure that the injection and medication that they take are at least 1 hour apart.”
“Most of the time, patients do take birth control before bedtime, so if the two are spaced, it should be OK,” she said.
Another option is for women to speak to their doctors about other contraceptive options like IUDs or implantable rods, where gastric absorption is not going to be an issue.
“There’s very little research on this class of drugs,” said Emily Goodstein, a 40-year-old small-business owner in Washington, who recently switched from Ozempic to Mounjaro. “Being a person who lives in a larger body is such a horrifying experience because of the way that the world discriminates against you.”
She appreciates the feeling of being proactive that these new drugs grant. It has “opened up a bunch of opportunities for me to be seen as a full individual by the medical establishment,” she said. “I was willing to take the risk, knowing that I would be on these drugs for the rest of my life.”
In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.
“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to.
Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah.
Clear conversations are key.

“Folks are really not talking about the reproductive implications,” she said, referring to members of a Facebook group on these drugs that she belongs to.
Like patients themselves, many doctors are just beginning to get their arms around these agents. “Awareness, education, provider involvement, and having a multidisciplinary team could help patients achieve the goals that they set out for themselves,” said Dr. Shah.
Clear conversations are key.

For women who are obese, daily life is wrought with landmines. Whether it’s the challenges of air travel because plane seats are too small, the need to shield themselves from the world’s discriminating eyes, or the great lengths many will go to achieve better health and the promise of longevity, navigating life as an obese person requires a thick skin.
So, it’s no wonder so many are willing to pay more than $1,000 a month out of pocket to get their hands on drugs like semaglutide (Ozempic and Wegovy) or tirzepatide (Mounjaro). The benefits of these drugs, which are part of a new class called glucagonlike peptide–1 (GLP-1) receptor agonists, include significant and rapid weight loss, blood sugar control, and improved life quality; they are unprecedented in a setting where surgery has long been considered the most effective long-term option.
On the flip side, the desire for rapid weight loss and better blood sugar control also comes with an unexpected cost. , making an unintended pregnancy more likely.
Neel Shah, MD, an endocrinologist and associate professor at the University of Texas Health Science Center at Houston, said he has had several patients become pregnant without intending to.
“It was when Mounjaro came out on the market when we started using it,” he said of the drug the Food and Drug Administration approved for type 2 diabetes in 2022. “It [the warning] was in the product insert, but clinically speaking, I don’t know if it was at the top of providers’ minds when they were prescribing Mounjaro.”
When asked if he believed that we were going to be seeing a significant increase in so-called Mounjaro babies, Dr. Shah was sure in his response.
“Absolutely. We will because the sheer volume [of patients] will increase,” he said.
It’s all in the gut
One of the ways that drugs like Mounjaro work is by delaying the time that it takes for food to move from the stomach to the small intestine. Although data are still evolving, it is believed that this process – delayed gastric emptying – may affect the absorption of birth control pills.
Dr. Shah said another theory is that vomiting, which is a common side effect of these types of drugs, also affects the pills’ ability to prevent pregnancy.
And “there’s a prolonged period of ramping up the dose because of the GI side effects,” said Pinar Kodaman, MD, PhD, a reproductive endocrinologist and assistant professor of gynecology at Yale University in New Haven, Conn.
“Initially, at the lowest dose, there may not be a lot of potential effect on absorption and gastric emptying. But as the dose goes up, it becomes more common, and it can cause diarrhea, which is another condition that can affect the absorption of any medication,” she said.
Unanticipated outcomes, extra prevention
Roughly 42% of women in the United States are obese, 40% of whom are between the ages of 20 and 39. Although these new drugs can improve fertility outcomes for women who are obese (especially those with polycystic ovary syndrome, or PCOS), only one – Mounjaro – currently carries a warning about birth control pill effectiveness on its label. Unfortunately, it appears that some doctors are unaware or not counseling patients about this risk, and the data are unclear about whether other drugs in this class, like Ozempic and Wegovy, have the same risks.
“To date, it hasn’t been a typical thing that we counsel about,” said Dr. Kodaman. “It’s all fairly new, but when we have patients on birth control pills, we do review other medications that they are on because some can affect efficacy, and it’s something to keep in mind.”
It’s also unclear if other forms of birth control – for example, birth control patches that deliver through the skin – might carry similar pregnancy risks. Dr. Shah said some of his patients who became pregnant without intending to were using these patches. This raises even more questions, since they deliver drugs through the skin directly into the bloodstream and not through the GI system.
What can women do to help ensure that they don’t become pregnant while using these drugs?
“I really think that if patients want to protect themselves from an unplanned pregnancy, that as soon as they start the GLP receptor agonists, it wouldn’t be a bad idea to use condoms, because the onset of action is pretty quick,” said Dr. Kodaman, noting also that “at the lowest dose there may not be a lot of potential effect on gastric emptying. But as the dose goes up, it becomes much more common or can cause diarrhea.”
Dr. Shah said that in his practice he’s “been telling patients to add barrier contraception” 4 weeks before they start their first dose “and at any dose adjustment.”
Zoobia Chaudhry, an obesity medicine doctor and assistant professor of medicine at Johns Hopkins University in Baltimore, recommends that “patients just make sure that the injection and medication that they take are at least 1 hour apart.”
“Most of the time, patients do take birth control before bedtime, so if the two are spaced, it should be OK,” she said.
Another option is for women to speak to their doctors about other contraceptive options like IUDs or implantable rods, where gastric absorption is not going to be an issue.
“There’s very little research on this class of drugs,” said Emily Goodstein, a 40-year-old small-business owner in Washington, who recently switched from Ozempic to Mounjaro. “Being a person who lives in a larger body is such a horrifying experience because of the way that the world discriminates against you.”
She appreciates the feeling of being proactive that these new drugs grant. It has “opened up a bunch of opportunities for me to be seen as a full individual by the medical establishment,” she said. “I was willing to take the risk, knowing that I would be on these drugs for the rest of my life.”
In addition to being what Dr. Goodstein refers to as a guinea pig, she said she made sure that her primary care doctor was aware that she was not trying or planning to become pregnant again. (She has a 3-year-old child.) Still, her doctor mentioned only the most common side effects linked to these drugs, like nausea, vomiting, and diarrhea, and did not mention the risk of pregnancy.

FDA panel rejects implanted GLP1-RA dosing device for T2D
Sept. 21 from an advisory committee of the Food and Drug Administration.
The 19 voting panel members mostly cited concerning signals of both renal toxicity in the form of excess episodes of acute kidney injury (AKI) as well as increased cardiovascular events compared with placebo as their main reasons for voting that the developing company, Intarcia Therapeutics, had not shown adequate evidence that the benefits of the drug-device combination, known as ITCA 650, outweighed its risks for treating people with type 2 diabetes.
“I’m quite uncomfortable with the AKI safety,” said panel member Erica Brittain, PhD, deputy chief of the Biostatistics Research Branch of the National Institute of Allergy and Infectious Diseases in Bethesda, Md.
The case that ITCA 650 is ready for routine use was also undermined by uncertainty documented by FDA staff about the uniformity and reliability of exenatide delivery by the DUROS device, a matchstick-sized reservoir that’s placed subcutaneously and designed to deliver exenatide continuously for 6 months at a time, noted Cecilia C. Low Wang, MD, chair of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee.
“No evidence of improved adherence”
Another shortcoming was no data on the impact that this form of drug delivery, first developed and FDA approved to treat patients with prostate cancer with leuprolide acetate, really accomplished its goal of improving adherence to a glycemic-control agent. Intarcia Therapeutics presented “no evidence of improved adherence,” said Dr. Low Wang, director of the Glucose Management Team at the University of Colorado Hospital.
However, she and several other panel members acknowledged the compelling comments from several patients and health care professionals experienced in using or administering the device who, during the public comment period, voiced anecdotal testimonials to its positive impact on treatment compliance.
Seven years of FDA review
This review of ITCA 650 capped a nearly 7-year effort by Intarcia Therapeutics to receive marketing approval for ITCA 650 from the FDA, which began with an application filed in November 2016 (and denied by the agency in September 2017). Intarcia resubmitted an amended application in 2019 that the FDA again rejected in 2020. The company’s persistence following that led to the current panel meeting, the first time the ITCA 650 evidence came before an advisory panel.
Committee members in general praised the concept of managing blood glucose by continuous release of a medication 6 months at a time. They also offered ideas on a path forward, such as a study that used an active competitor. Ideally, that could be another agent from the same class of GLP-1 receptor agonists such as Bydureon, an injected formulation of exenatide administered by subcutaneous injection once a week.
But the key, agreed panel members, was to bulk up the evidence that ITCA 650 is safe. “The data show concerning safety signals that need further investigation,” summed up Dr. Low Wong. “There are concerns about overall safety, all-cause mortality, AKI, cardiovascular events, and glycemic excursions.”
All voting members of the advisory committee met the FDA’s standard for having no relevant financial relationships.

Exercise timing may dictate obesity, type 2 diabetes risk
Tongyu Ma, PhD, research assistant professor with the Health Sciences Department, Franklin Pierce University, Rindge, N.H., and colleagues studied data on almost 5,300 individuals, finding a strong association between moderate to vigorous physical activity (MVPA) and obesity.
The research, published in Obesity, showed that people who exercised in the morning had a lower body mass index than that of those who exercised at other times, even though they were more sedentary.
For the second study, Chirag J. Patel, PhD, associate professor of biomedical informatics at Harvard Medical School, Boston, and colleagues examined more than 93,000 individuals and found that morning and afternoon, but not evening, exercise reduced the risk for type 2 diabetes.
However, the results, published in Diabetologia, also indicated that people who undertook at least MVPA were protected against developing type 2 diabetes no matter what time of day they exercised.
Along with considering the timing of exercise, the authors suggest that it is “helpful to include some higher intensity activity to help reduce the risk of developing diabetes and other cardiovascular disease.”
Morning exercisers perform less physical activity
Dr. Ma and colleagues noted that “although a beneficial association among the levels of physical activity with obesity has been frequently reported, the optimal timing of physical activity for decreasing obesity remains controversial.”
The researchers analyzed data from the National Health and Nutrition Examination Survey for the 2003-2004 and 2005-2006 cycles, because accelerometry was implemented in those periods.
They included 5,285 individuals aged ≥ 20 years who had physical activity measured via an accelerometer worn on the right hip during waking hours for 7 consecutive days.
The diurnal pattern of MVPA was classified into three clusters by the established technique of K-means clustering analysis: morning (n = 642), midday (n = 2,456), and evening (n = 2,187).
The association between MVPA, diurnal pattern, and obesity was then assessed in linear regression models taking into account a range of potential confounding factors.
Overall, participants in the morning cluster were older and more likely to be female than those in the other clusters (P < .001 for both). They were also more likely to be nonsmokers (P = .007) and to have less than high school education (P = .0041).
Morning cluster individuals performed less physical activity and were more sedentary than those in the midday and evening groups (P < .001 for both), although they were more likely to be healthy eaters (P = .004), with a lower calorie intake (P < .001).
Individuals in the morning cluster had, on average, a lower body mass index than those in other clusters, at 27.4 vs. 28.4 in the midday cluster and 28.2 in the evening cluster (P for interaction = .02).
Morning cluster participants also had a lower waist circumference than participants in the midday or evening cluster: 95.9 cm, 97.9 cm, and 97.3 cm, respectively (P for interaction = .06).
The team reported that there was a strong linear association between MVPA and obesity in the morning cluster, whereas there was a weaker curvilinear association in the midday and evening clusters.
“This is exciting new research that is consistent with a common tip for meeting exercise goals – that is, schedule exercise in the morning before emails, phone calls, or meetings that might distract you,” Rebecca Krukowski, PhD, professor, public health sciences, University of Virginia, Charlottesville, said in a release.
However, she noted that the cross-sectional nature of the study means that it is “not known whether people who exercise consistently in the morning may be systematically different from those who exercise at other times, in ways that were not measured in this study.
“For example, people who exercise regularly in the morning could have more predictable schedules, such as being less likely to be shift workers or less likely to have caregiving responsibilities that impede morning exercise,” said Dr. Krukowski, who was not involved in the study.
No association between evening activity and type 2 diabetes risk
In the second study, the team studied 93,095 persons in the UK Biobank, with a mean age of 62 years and no history of type 2 diabetes, who wore a wrist accelerometer for 1 week.
The movement data were used to estimate the metabolic equivalent of task, which was then summed into the total physical activity completed in the morning, afternoon, and evening and linked to the development of incident type 2 diabetes.
After adjustment for potential confounding factors, both morning and afternoon physical activity were associated with a reduced risk of developing type 2 diabetes, at hazard ratios of 0.90 (P = 7 × 10-8) and 0.91 (P = 1 × 10-5), respectively.
However, there was no association between evening activity and the risk for type 2 diabetes, at a hazard ratio of 0.95 (P = .07).
The team found, however, that MVPA and vigorous physical activity were associated with a reduced risk for type 2 diabetes at all times of day.
Dr. Patel’s study was supported in part by National Institutes of Health grants. No other funding was declared. No relevant financial relationships were declared.
