STEP 1 Trial

Meaning

The STEP 1 Trial, formally titled “Semaglutide Treatment Effect in People with Obesity,” was a pivotal, multi-center, randomized, double-blind, placebo-controlled phase 3 clinical trial. This landmark study investigated the efficacy and safety of once-weekly subcutaneous semaglutide for chronic weight management in non-diabetic adults with obesity or overweight and at least one weight-related comorbidity. The trial provided robust evidence for the significant and sustained weight loss potential of GLP-1 receptor agonists, fundamentally changing the landscape of obesity pharmacotherapy and establishing a new benchmark for intervention.
