Jiangsu Hengrui Pharmaceuticals’ injected GLP-1/GIP agonist helped obese patients in a China-based trial lose around 18% of their weight after around 11 months’ treatment, Hengrui and its US partner Kailera Therapeutics said Tuesday. On a cross-trial basis, this is not bad, marginally beating what Eli Lilly’s similarly acting Zepbound showed at one year in its own pivotal China trial. In Phase 2, a higher dose of Hengrui’s drug, called HRS9531, posted weight loss of 22.8% after just
eight months. Adjusted for placebo, weight loss in the Phase 3 trial was 16.3%, again better than the 15.2% seen with the high dose of Zepbound. A prespecified supplementary analysis found that the highest dose, 6 mg weekly, allowed patients to lose 19.2% of their weight, or 17.7% when adjusted for placebo. |
