Semaglutide shows sustained weight loss benefits in older adults
In continuation of my update on semaglutide
A new analysis of the STEP trails carried out by semaglutide manufacturer Novo Nordisk has analysed various trials to show the safety and efficacy of the obesity drug semaglutide in older adults (over 65 years), and found similar efficacy and safety as in the general trial populations . The study is by Prof Luca Busetto from the University of Padova in Italy and colleagues including from Novo Nordisk, who sponsor this new study.
Of the total population in the selected trials (N=4523), 358 participants (8%) were aged 65 years or older and included in the analysis (semaglutide 2.4 mg, n=248; placebo, n=110), with most (90%) being aged 65–74 years (and the others 75 years and over). Across the pooled semaglutide and placebo groups at baseline, mean age was 69 years, bodyweight was 99.0 kg, BMI was 36.6 kg/m² and waist circumference was 115 cm; 72% were female.
At week 68, there was a mean −15.4% change in body weight for semaglutide 2.4 mg vs −5.1% for placebo, and a mean −14.3 cm vs −6.0 cm change in waist circumference, respectively. Proportions of participants achieving body weight reduction thresholds in the semaglutide 2.4 mg vs placebo groups were 66.5% vs 15.5% (at least 10%), 46.8% vs 6.4% (at least 15%) and 28.6% vs 2.7% (at least 20%), respectively.
In the semaglutide 2.4 mg group, 11.3% achieved a WHtR <0.53, compared with 4.5% with placebo. A greater proportion of semaglutide-treated participants improved their BMI category from baseline to week 68 compared with placebo (see Figure full abstract). A BMI of <27 kg/m² (so called healthy weight) was achieved by 27.0% of participants in the semaglutide group vs 5.5% in the placebo group; and the proportion of elderly patients in the overweight and obesity class I, II and III categories all fell in the semaglutide group at week 68 due to the increase in participants who had reached a healthy weight.
For participants achieving both a BMI of 27 or less and a WHtR of <0.53 these values were 10.5% vs 2.7%, respectively. Greater improvements in cardiometabolic risk factors were observed with semaglutide 2.4 mg vs placebo (see Table full abstract), including blood pressure, blood fats, cholesterol and glycated haemoglobin (HbA1c – a measure of blood sugar control used in diagnosis of diabetes).
Proportions of participants experiencing AEs and serious AEs in the semaglutide 2.4 mg vs placebo groups were similar for AEs overall (89.1% vs 84.5%), but higher for semaglutide re: serious AEs - 19.0% vs 12.7%, respectively. Constipation and dizziness rates (known side effects of this class of drug) were higher with semaglutide, while fractures and hypoglycaemia were comparable to placebo, both affecting less than 1% in each group.

Legumes and soy foods may help reduce hypertension risk
In continuation of my continuation of my update on soy ..
A higher dietary intake of soy and legumes is linked to a lower risk of high blood pressure, finds a pooled data analysis of the available evidence, published in the open access journal BMJ Nutrition Prevention & Health.
And the optimal daily amount may be around 170 g of legumes, which include peas, lentils, chickpeas and beans, and 60 to 80 g of soy foods, examples of which include tofu, soy milk, edamame, tempeh, and miso, the findings indicate.
Legumes and soy foods have been associated with an overall lower risk of cardiovascular disease, but the evidence on their potential for lowering high blood pressure is mixed and needs to be systematically quantified, explain the researchers.
To explore this further, the researchers scoured databases for relevant studies published up to June 2025, and found 10 publications that included data from 12 prospective observational studies.
Five studies were from the USA, 5 from Asia (China, Iran, South Korea and Japan), and 2 were from Europe (France and the UK). Nine studies included both men and women, 2 included only women, and 1 included only men.
The number of study participants ranged from 1152 to 88,475 and the number of cases of high blood pressure ranged from 144 to 35,375.
Pooled data analysis of the study findings showed that higher daily intake of legumes and soy foods was associated with a lower risk of developing high blood pressure.
Compared with those with a low intake of legumes, those with a high intake were 16% less likely to develop high blood pressure. Similarly, those with a high intake of soy foods were 19% less likely to develop the condition than those with a low intake.
When assessing the association between quantity and lower risk, a linear reduction (30%) emerged for legumes up to around 170 g/day, while most of the reduction in risk (28-29%) for soy foods was observed at between 60 and 80 g/day, with no further reduction in risk at higher intake.
One hundred grams of legumes/soy is equivalent to a serving size of about one cup or 5–6 tablespoons of cooked beans, peas, chickpeas, lentils, soybeans or a palm-size serving of tofu, explain the researchers.
Using World Cancer Research Fund evidence grading criteria for evaluating the likelihood of causality, the researchers consider the overall evidence to indicate a probable causal relationship between both legume and soy intake and a reduced risk of high blood pressure.
There are plausible explanations for the findings, they say. Legumes and soy are high in potassium, magnesium, and dietary fiber, all of which are known for their blood pressure lowering properties.
And recent research has suggested that the fermentation of soluble fiber from legumes and soy produces short-chain fatty acids that influence blood vessel dilation, while the isoflavone content of soy also seems to help lower blood pressure, they explain.
The researchers acknowledge various limitations to their findings, including the variability of the studies in the pooled data analysis. This included differences in legume types, levels of intake, preparation methods, dietary contexts, and the definition of high blood pressure.
"Despite these limitations, the findings of this meta-analysis have major public health implications, given the alarming global increase in hypertension prevalence," they point out.
"Current legume consumption across Europe and the UK remains below dietary recommendations, with average intakes of only 8–15 g/day, far below the recommendations of 65 to 100 g/day recommended for overall cardiovascular health," they add.
"Although further large-scale cohorts are needed for confirmation, these findings provide further evidence in support of dietary recommendations to the public to prioritise and integrate legumes and soy foods as healthy protein sources in the diet," they conclude.
"This research strengthens the evidence base for the cardioprotective benefits of plant-based diets. The authors have significantly added to the case for using legumes and soy as primary dietary strategies to mitigate the global burden of hypertension," comments Professor Sumantra Ray, chief scientist and executive director of NNEdPro Global Institute for Food, Nutrition and Health, which co-owns BMJ Nutrition Prevention & Health.
"The strengths of the study lie in its rigorous dose-response analyses, which offer practical dietary targets for use in public health guidelines and clinical practice. But we can't entirely rule out the influence of unmeasured influential factors. And the plateauing of benefits for soy at 60–80 g/day warrants further investigation, as it remains unclear if this reflects a true biological limit or is a byproduct of the smaller number of studies available for analysis."

Metformin's real power may be in the gut
The body relies on glucose as a fast and versatile fuel, but too much glucose can lead to insulin resistance and ultimately damage blood vessels and organs. The study found metformin slows mitochondrial energy production in gut cells, forcing the intestine to metabolize extra sugar.
"Metformin essentially helps the intestine suck the glucose out of the bloodstream, which further highlights that the gut plays a major role in regulating blood sugar levels," said corresponding author Navdeep Chandel, professor of biochemistry and molecular genetics at Northwestern University Feinberg School of Medicine.
The study is published in Nature Metabolism.
The study builds off findings from previous work in Chandel's lab, which found metformin lowers blood sugar by blocking a specific part of the cell's energy-making machinery called mitochondrial complex I, a key enzyme in cellular respiration.
The new study furthers that work by pinpointing the specific tissue targeted by metformin. The findings suggest directing drugs or supplements to the gut could be an effective strategy for controlling blood sugar, Chandel said.
Chandel is also the David W. Cugell, MD, Professor of Medicine (Pulmonology and Critical Care), Biochemistry and Molecular Genetics and an investigator with the Chan Zuckerberg Initiative. The study's first author is Zach Sebo, a postdoctoral fellow in the Chandel lab who will soon start his own research group at the University of Kansas School of Medicine.
"Our study suggests that revisiting assumptions about metformin's mechanism may offer a more detailed understanding of how it works," Sebo said.

Cogent Biosciences Announces Submission of New Drug Application for Bezuclastinib in Gastrointestinal Stromal Tumors (GIST)
Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, announced the completion of the submission of its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for bezuclastinib in patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib. Based on the positive results from the PEAK trial, the bezuclastinib NDA was submitted under the FDA’s Real-Time Oncology Review (RTOR) program, which is intended to enable a more streamlined review process. Bezuclastinib was also granted Breakthrough Therapy Designation as a treatment for GIST earlier this year.
- Bezuclastinib NDA submitted under the FDA’s RTOR program based on positive results from Phase 3 PEAK trial; bezuclastinib previously granted Breakthrough Therapy Designation in GIST
- Bezuclastinib combination demonstrated 16.5 month mPFS and 46% ORR in imatinib-resistant GIST patients, dramatically improving upon the current standard of care
“We are excited to complete our PEAK NDA submission which marks a significant step toward bringing a new therapy to patients with second-line GIST,” said Andrew Robbins, President and Chief Executive Officer. “Based on the strength of the PEAK data, we believe the bezuclastinib combination has the potential to meaningfully change the treatment landscape for these patients. We are grateful to the patients, investigators, and study teams who made this possible.”
Pivotal data from PEAK, a global, randomized Phase 3 clinical trial evaluating bezuclastinib in combination with sunitinib vs. sunitinib monotherapy in patients with GIST who have received prior treatment with imatinib, were reported in November 2025. As disclosed in the top-line results, the bezuclastinib combination demonstrated a substantial and highly statistically significant clinical benefit on the primary endpoint of progression free survival (PFS), reducing risk of disease progression or death compared to the current standard of care by 50% (hazard ratio of 0.50, 95% CI: 0.39 – 0.65). mPFS, as assessed by blinded independent central review, was 16.5 months for the bezuclastinib combination vs. 9.2 months for sunitinib monotherapy. Additionally, the bezuclastinib combination demonstrated an unprecedented ORR in imatinib-resistant patients, with 46% of patients treated with the bezuclastinib combination achieving an objective response compared to 26% of patients treated with sunitinib. The bezuclastinib combination was generally well tolerated, and no unique risks were observed with the novel combination when compared to the known safety profile of sunitinib. Data for overall survival remains immature.

Some Improvement Seen in Cognitive Function With Exercise, Ibuprofen in Cancer
In continution of my update on Ibuprofen
For adults with cancer receiving chemotherapy, an exercise intervention and low-dose ibuprofen improved some domains of cognitive function, according to a study published online April 20 in Cancer.
Michelle C. Janelsins, Ph.D., M.P.H., from the University of Rochester in New York, and colleagues randomly assigned 86 adult participants with cancer receiving chemotherapy and reporting cognitive problems to one of four study arms for six weeks: Exercise for Cancer Patients (EXCAP)-ibuprofen, EXCAP-placebo, ibuprofen only, and placebo only. EXCAP is a home-based, low- to moderate-intensity progressive walking and resistance exercise prescription.
The researchers found that compared with the placebo group, participants in the EXCAP-placebo group had significantly better attention performance on the Trail Making Test (–21.57 seconds). Greater improvements were seen for the ibuprofen-only group versus the placebo group (difference of –11.27 seconds). Improvements on the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) "comments from others" subscale were exhibited by participants in both the EXCAP-ibuprofen and EXCAP-placebo groups compared with the placebo group. Participants in the EXCAP-placebo group had a significant improvement on Rapid Visual Processing mean latency compared with the placebo group; those receiving ibuprofen had an improvement compared with those receiving placebo, which was attributed to a trend after adjustment for reading score. Compared with those not receiving ibuprofen, the ibuprofen group performed less well on the Hopkins Verbal Learning Test‐Revised delayed.
"We are encouraged by the findings of this trial that suggest possible benefits of both interventions for some cognitive domains. Clearly, we saw a more pronounced effect with exercise, which is notable considering the multiple health benefits of exercise for cancer survivors," Janelsins said in a statement.

Combining Cannabinoid With Opioid Does Not Relieve Pain in Knee Osteoarthritis
For patients with knee osteoarthritis, combining a cannabinoid medication with an opioid does not provide additional pain relief, according to a study published in the May issue of Anesthesiology.
Katrina R. Hamilton, Ph.D., from Johns Hopkins University School of Medicine in Baltimore, and colleagues examined the acute analgesic and drug effects of synthetic delta-9-tetrahydrocannabinol and hydromorphone, alone and in combination, in 21 individuals with knee osteoarthritis (mean age, 63.4 years). Participants received oral combinations of placebo, hydromorphone (2 mg), and dronabinol (10 mg).
The researchers found greater pressure pain threshold analgesia for hydromorphone than dronabinol and greater capsaicin and noncapsaicin sensitized mechanical temporal summation analgesia versus placebo. No significant drug-related differences were seen for clinical pain severity, thermal threshold or tolerance, temporal summation, cold pressor, conditioned pain modulation, capsaicin-induced thermal threshold, central sensitization, general pain sensitivity, or physical functioning (two-minute walking distance, Timed Up and Go, and total stair climb time). Compared with all conditions, hydromorphone impaired working memory accuracy and produced greater good effects than placebo in terms of secondary outcomes. Working memory reaction time was impaired with hydromorphone + dronabinol, which produced greater high ratings than placebo, greater drug effects than placebo + hydromorphone, and higher nausea than hydromorphone. Greater high ratings were seen for dronabinol than hydromorphone.
"Some patients believe combining cannabis with opioids can help with pain, and clinicians may recommend or prescribe it in states where cannabis is legal," Hamilton said in a statement. "Our study suggests that isn't the case and patients may experience more side effects when the drugs are combined."

FDA Approves Idvynso (doravirine and islatravir) for the Treatment of HIV-1 Infection in Adults
In continuation of my update on Doravirine
Merck (NYSE: MRK), known as MSD outside of the United States and Canada, announced the U.S. Food and Drug Administration (FDA) approval of Idvynso, a new, two-drug single-tablet regimen of 100 mg doravirine and 0.25 mg islatravir, for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no history of virologic treatment failure and no known substitutions associated with resistance to doravirine. Idvynso is contraindicated when co-administered with drugs that are strong cytochrome P450 (CYP)3A enzyme inducers and lamivudine (3TC) or emtricitabine (FTC). Co-administration with these drugs may decrease the effectiveness of Idvynso. See additional selected safety information on the following pages. Idvynso (pronounced ihd-VIHN-soh) will be available in pharmacies after May 11.
Islatravir
- Idvynso is approved for adults with virologically suppressed HIV-1 with no history of virologic treatment failure and no known substitutions associated with resistance to doravirine
- Idvynso is the first and only non-INSTI, tenofovir-free, once-daily, complete two-drug regimen to demonstrate non-inferior efficacy in a head-to-head Phase 3 trial versus three-drug regimen Biktarvyi (BIC/FTC/TAF)
“Advances in HIV treatment mean more people living with HIV are living longer — a remarkable achievement,” said Carl Baloney, Jr., president and chief executive officer of AIDS United. “People aging with HIV face additional health challenges, including managing multiple chronic conditions and medications at the same time. It is essential that management of HIV considers these factors in addition to virologic suppression when choosing an HIV treatment regimen.”
“Idvynso combines islatravir, a next-generation NRTI with multiple mechanisms of action, including translocation inhibition, with doravirine, an NNRTI with an established efficacy and safety profile. As the only two-drug, non-INSTI, tenofovir-free regimen, Idvynso expands therapeutic diversity beyond the currently available oral treatment options,” said Dr. Eliav Barr, senior vice president and chief medical officer, Merck Research Laboratories. “As the health needs of adults living with HIV change over time, Idvynso gives clinicians a new choice for HIV treatment. This approval marks an important new chapter in Merck’s long-standing commitment to research and discovery for people living with HIV.”
Idvynso is a complete regimen; co-administration with other antiretroviral medications for treatment of HIV-1 infection is not recommended. Severe skin reactions, including Stevens-Johnson syndrome/toxic epidermal necrolysis, have been reported with doravirine-containing regimens. Drug Rash with Eosinophilia and Systemic Symptoms was reported with Idvynso. Concomitant use of Idvynso and certain other drugs may result in known or potentially significant drug interactions, some of which may lead to loss of therapeutic effect of Idvynso and possible development of resistance, or possible clinically significant adverse reactions from greater exposures of a component of Idvynso. See additional selected safety information on the following pages.
“Idvynso is the first non-INSTI, tenofovir-free, two-drug regimen to demonstrate non-inferior efficacy to standard oral antiretroviral regimens, including Biktarvy. This makes Idvynso a potential alternative for people with virologically suppressed HIV who may need to switch their treatment,” said Dr. Amy Colson, director of research at Community Resource Initiative, Boston, Massachusetts.
Phase 3 studies supporting approval of Idvynso
The efficacy and safety of Idvynso is supported by Week 48 data from two randomized, active-controlled, non-inferiority trials [Trial 052 (NCT05630755) and Trial 051 (NCT05631093)] in virologically-suppressed (HIV-1 RNA less than 50 copies per mL) adults living with HIV. Participants must have been stably suppressed on their baseline regimen for at least 3 months prior to trial entry and had no history of treatment failure. Across the two trials, a total of 708 participants received once-daily Idvynso; of these, 81 (11%) participants were aged 65 years and older, including 10 (1%) aged 75 years and older.
In the double-blind Trial 052, participants were switched from Biktarvy [bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF)] to Idvynso. A total of 513 participants were randomized (2:1) and were switched to once-daily Idvynso (n=342) or remained on BIC/FTC/TAF (n=171). At baseline, participants had a mean age of 48 years (range: 19 to 77), 21% of participants were female, 61% were White, 31% were Black/African American, and 6% were Asian. A total of 23% identified as Hispanic/Latino.
In the open-label Trial 051, participants were switched from an oral ART (antiretroviral therapy) regimen to Idvynso. A total of 551 participants were randomized (2:1) and were switched to once-daily Idvynso (n=366) or remained on their baseline ART (bART) (n=185). Randomization was stratified by bART. At baseline, participants had a mean age of 50 years (range: 18 to 83), 40% of participants were female, 39% were White, 45% were Black/African American, and 5% were Asian. A total of 15% identified as Hispanic/Latino. At enrollment, 64% of the participants were receiving integrase strand transfer inhibitor (INSTI)-based regimens, 5% protease inhibitor (PI)-based regimens (including combinations with INSTI), and 30% were receiving other regimens.

Experimental drug cuts Parkinson's-linked protein up to 60% in early trial
Scientists have long believed that lowering the activity of the LRRK2 protein could help slow or modify the disease, but turning that idea into a viable therapy has remained a challenge, said co-author of the study Danielle Larson, MD, '15, '18 GME, assistant professor in the Ken & Ruth Davee Department of Neurology's Division of Movement Disorders.
"This was a multicenter clinical trial looking at an antisense oligonucleotide therapy for LRRK2-specific Parkinson's disease," Larson said. "The main goal was to examine the safety of delivering this therapy to patients, with the hope that if it proved safe, future studies could evaluate whether it might slow disease progression."
The study tested whether BIIB094 could safely reduce LRRK2 levels in people with Parkinson's disease. The results suggest it can be done without serious safety concerns, Larson said.
In the randomized, placebo-controlled trial, 82 participants with Parkinson's disease were enrolled across two study segments. In the first, 40 participants received a single dose of BIIB094 or placebo. In the second, 42 participants received four doses of the drug or placebo, administered every four weeks. The therapy was delivered intrathecally: directly into the cerebrospinal fluid through a lumbar puncture.
Participants in the second section were stratified based on whether they carried a known LRRK2 genetic variant.
Across both parts of the trial, the treatment was generally well tolerated. While adverse events were common, they were mostly mild to moderate and did not limit dosing. No serious adverse events related to BIIB094 were reported, according to the study.
