Is this trial a fit for you?
✓Likely a good fit
Adults age 18 and older with BMI ≥27 with a weight-related comorbidity or BMI ≥30, who have attempted dietary weight loss in the past.
✕Probably not a fit
Individuals without sufficient weight loss or who do not tolerate the medication may not experience benefit.

What this trial studies
This Phase 3 interventional trial compares oral semaglutide at lower doses to placebo in adults with excess body weight. Eligible participants have BMI ≥27 with at least one weight-related condition or BMI ≥30, and a history of trying to lose weight with diet. The study will identify the most effective lower dose to support weight loss while monitoring safety. It uses a randomized, placebo-controlled design to assess weight change over a defined period. Lead sponsor is Novo Nordisk, with sites in Alabama and California.
Why it matters
Potential benefit: If successful, participants may achieve greater weight loss and improvements in related health risks with a convenient oral medication option.
How similar studies have gone: Previous studies of GLP-1 receptor agonists have shown meaningful weight loss, supporting the potential for benefit with similar approaches.
