Phase 2 Trial Design Participants: 338 adults with obesity (BMI 30) or overweight with comorbidities (BMI 27), without diabetes Duration: 48 weeks Dosing groups: Placebo, 1mg, 4mg, 8mg, or 12mg weekly (with gradual dose escalation over 20-24 weeks) Primary endpoint: Percentage change in body weight from baseline Beyond Weight Loss: Metabolic Improvements Beyond weight loss, the 12mg dose also improved several cardiometabolic markers: Blood pressure: Systolic BP decreased by 7.4 mmHg (clinically significant reduction) Lipids: Triglycerides fell 30%, HDL cholesterol increased 8% Glucose control: HbA1c decreased 0.4% even in participants without diabetes Liver health: Markers of fatty liver disease (ALT, AST) improved significantly Inflammation: C-reactive protein (CRP) decreased, indicating reduced systemic inflammation What this means: Retatrutide appears to improve the metabolic dysfunction behind obesity-related diseases, not just the weight itself

Ever since SGLT2is and GLP1RAs demonstrated cardiovascular benefits in cardiovascular outcome trials (CVOTs), studies have attempted to elucidate the mechanisms of these drugs in reducing cardiovascular events
