Safety profile of semaglutide versus placebo in the SELECT study: a randomized controlled trial

Obesity (Silver Spring)Published Secondary analysis of the SELECT randomised controlled trial

Authors' conclusion

The long-term safety profile observed in the Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity (SELECT) study is consistent with previously reported semaglutide studies. No new safety concerns were identified for once-weekly semaglutide 2.4 mg.

Study context

Population
Patients with established CVD and overweight or obesity
Comparison
Once-weekly subcutaneous semaglutide 2.4 mg vs placebo
Primary endpoint
Safety: SAEs, all adverse events (AEs) leading to permanent treatment discontinuation, and prespecified AEs of special interest
