§
Mounjaro is not indicated to improve key cardiometabolic parameters, including waist circumference, blood pressure( systolic and diastolic), cholesterol( total, non-HDL, HDL, and LDL) and triglycerides. 1 Cardiometabolic parameters were secondary endpoints in SURMOUNT-1 and SURMOUNT-4. 4, 5
SURMOUNT-1: Waist circumference: Mounjaro 5 mg, 10 mg and 15 mg vs placebo, p < 0.001( 5 mg not adjusted for multiplicity). 1 Triglycerides, HDL and non-HDL cholesterols, and systolic blood pressure: pooled Mounjaro groups vs placebo, p < 0.001; diastolic blood pressure and total and LDL cholesterols, p-values not reported. 5 Key secondary endpoints were adjusted for multiplicity. 5 SURMOUNT-4: systolic and diastolic blood pressure, triglycerides and LDL cholesterol, p < 0.001, Mounjaro MTD vs placebo, not adjusted for multiplicity; HDL cholesterol, p = 0.014, Mounjaro MTD vs placebo, not adjusted for multiplicity. 4
SURMOUNT-1 was powered to show superiority of Mounjaro( 10 mg, 15 mg, or both) to placebo with respect to the coprimary endpoints from baseline to week 72. 5
Studied in adults with obesity( BMI of ≥30 kg / m 2) or with overweight( BMI of ≥27 kg / m 2 to < 30 kg / m 2) with at least 1 weight-related complication, excluding type 2 diabetes. 1 All participants in SURMOUNT-1 and SURMOUNT-4 received lifestyle intervention, including a reduced-calorie diet and increased physical activity. 1, 4, 5
SURMOUNT-4 was a Phase 3 clinical trial with a 36-week lead-in period, in which all participants received Mounjaro maximum tolerated dose( 10 mg or 15 mg), and a 52-week double-blind period, in which participants were randomised to MTD or placebo. 4
Safety profile: Common adverse events with Mounjaro in SURMOUNT-1 and SURMOUNT-4 included nausea, diarrhoea, constipation and vomiting. 4, 5 These adverse events were mostly mild or moderate in severity, occurred more often during dose escalation, and decreased over time. 1, 4, 5
