Abstract: A brand new trial reveals that weekly injections of the weight-loss drug Wegovy (semaglutide) lowered the danger of loss of life from COVID-19 by a few third and diminished general mortality by 19%.
The research adopted greater than 17,000 members with coronary heart illness and weight problems, exhibiting that Wegovy decreased the chance of loss of life from heart problems by 15% and different causes by 23%.
The findings are shocking, because the drug additionally lessened COVID-19 severity regardless of equal an infection charges in each the Wegovy and placebo teams. Additional research are wanted to know the mechanisms behind these advantages.
Key Details:
- Wegovy diminished the danger of loss of life from COVID-19 by 33% in trial members.
- Total mortality decreased by 19% for these on Wegovy in comparison with placebo.
- The research adopted over 17,000 members with coronary heart illness and weight problems.

A trial research has discovered that injections of the weight-loss drug Wegovy diminished the danger of deaths from COVID-19 by a few third whereas additionally considerably decreasing threat of loss of life from heart problems or some other trigger.
The trial was led by Harvard-affiliated Brigham and Girls’s Hospital. It was funded by Novo Nordisk, makers of Wegovy (the model identify of semaglutide).
From October 2018 via March 2023, researchers studied the impact of once-weekly Wegovy photographs versus placebo on mortality in additional than 17,000 members with coronary heart illness and chubby or weight problems.
The research confirmed that sufferers on Wegovy had been about 15 p.c much less more likely to die from heart problems and 23 p.c much less doubtless from different causes as in comparison with those that took a placebo.
Total loss of life charges within the group taking Wegovy had been 19 p.c decrease in comparison with placebo.
“The trial began earlier than COVID-19, and we by no means anticipated a world respiratory pandemic,” mentioned corresponding creator Benjamin M. Scirica, director of high quality initiatives at BWH’s Cardiovascular Division and professor of medication at Harvard Medical College.
“It’s uncommon for a cardio-metabolic drug to switch non-cardiovascular outcomes,” Scirica added.
“The truth that semaglutide diminished non-cardiovascular loss of life, and particularly COVID-19-related deaths, was shocking. It opens up new avenues for exploring how this class of medication could profit sufferers.”
Within the research, folks taking Wegovy had been simply as more likely to get COVID-19, however they’d fewer critical sicknesses or deaths associated to COVID-19.
The researchers have no idea if the advantage of Wegovy is because of weight reduction or different results, however counsel that further weight often is the biggest contributor to decrease life expectancy.
This result’s from only one remark, albeit in a big, multinational research, so the findings have to be replicated. Additional research will discover potential mechanisms of motion, and different research of medication on this class ought to present further knowledge.

“The Impact of Semaglutide on Mortality and COVID-19–Associated Deaths: An Evaluation From the SELECT Trial” by Benjamin M. Scirica et al. Journal of the American Faculty of Cardiology
Summary
The Impact of Semaglutide on Mortality and COVID-19–Associated Deaths: An Evaluation From the SELECT Trial
Background
Sufferers with chubby and weight problems are at elevated threat of loss of life from a number of causes, together with cardiovascular (CV) loss of life, with few therapies confirmed to cut back the danger.
Aims
This research sought to evaluate the impact of semaglutide 2.4 mg on all-cause loss of life, CV loss of life, and non-CV loss of life, together with subcategories of loss of life and loss of life from coronavirus disease-2019 (COVID-19).
Strategies
The SELECT (Semaglutide Results on Cardiovascular Outcomes in Sufferers With Obese or Weight problems) trial randomized 17,604 members ≥45 years of age with a physique mass index ≥27 kg/m2 with established CV illness however with out diabetes to once-weekly subcutaneous semaglutide 2.4 mg or placebo; the imply trial period was 3.3 years. Adjudicated causes of all deaths, COVID-19 instances, and related deaths had been captured prospectively.
Outcomes
Of 833 deaths, 485 (58%) had been CV deaths, and 348 (42%) had been non-CV deaths. Contributors assigned to semaglutide vs placebo had decrease charges of all-cause loss of life (HR: 0.81; 95% CI: 0.71-0.93), CV loss of life (HR: 0.85; 95% CI: 0.71-1.01), and non-CV loss of life (HR: 0.77; 95% CI: 0.62-0.95).
The most typical causes of CV loss of life with semaglutide vs placebo had been sudden cardiac loss of life (98 vs 109; HR: 0.89; 95% CI: 0.68-1.17) and undetermined loss of life (77 vs 90; HR: 0.85; 95% CI: 0.63-1.15). An infection was the commonest reason for non-CV loss of life and occurred at a decrease charge within the semaglutide vs the placebo group (62 vs 87; HR: 0.71; 95% CI: 0.51-0.98).
Semaglutide didn’t cut back incident COVID-19; nonetheless, amongst members who developed COVID-19, fewer members handled with semaglutide had COVID-19–associated critical opposed occasions (232 vs 277; P = 0.04) or died of COVID-19 (43 vs 65; HR: 0.66; 95% CI: 0.44-0.96).
Excessive charges of infectious deaths occurred throughout the COVID-19 pandemic, with much less infectious loss of life within the semaglutide arm, and resulted in fewer members within the placebo group being in danger for CV loss of life.
Conclusions
In comparison with placebo, sufferers handled with semaglutide 2.4 mg had decrease charges of all-cause loss of life, pushed equally by CV and non-CV loss of life. The decrease charge of non-CV loss of life with semaglutide was predominantly due to fewer infectious deaths.
These findings spotlight the impact of semaglutide on mortality throughout a broad inhabitants of sufferers with CV illness and weight problems.
