Obesity challenger reveals impressive Phase II data

14 January 2025

Jiangsu Hengrui Pharmaceuticals (SHA: 600276) and Kailera Therapeutics have unveiled Phase II trial data for their obesity drug HRS9531, a GLP-1/GIP receptor dual agonist.

The findings, which show 21.1% placebo-adjusted weight loss at 36 weeks, suggest the treatment could challenge established market leaders in the competitive obesity space.

The Chinese study involved 61 participants with overweight or obesity, with 49 receiving a once-weekly 8 mg dose of HRS9531. Nearly 60% of those treated achieved a weight loss of at least 20%, and weight reduction continued beyond the 36-week mark.
