Hengrui’s HRS9531 Injection Clears NMPA Approval, Hits 19.2% Weight Loss in Phase 3

China‑based Jiangsu Hengrui Pharmaceuticals Co., Ltd. (HKG: 1276, SHA: 600276) confirmed that China’s National Medical Products Administration (NMPA) has accepted the marketing filing for its HRS9531 Injection, a novel dual agonist targeting the GLP‑1 and GIP receptors for long‑term weight management.

Product Profile

  • Indication – Adults with BMI ≥ 28 kg/m² (obesity) or BMI ≥ 24 kg/m² (overweight) plus at least one weight‑related comorbidity (hyperglycemia, hypertension, dyslipidemia, OSA, fatty liver, etc.).
  • Mechanism – Dual GLP‑1/GIP receptor agonist, developed in‑house, designed to enhance satiety and improve insulin sensitivity.
  • Safety – Phase 3 data demonstrate a favorable safety and tolerability profile.

Phase 3 Success

MetricResult
Primary EndpointMet (significant weight reduction vs. placebo)
Key Secondary EndpointsMet (including waist circumference, HbA1c, BP)
High‑Dose Mean Weight Loss19.2 %
≥20 % Weight Loss44.4 % of subjects
Trial Size567 adults with obesity/overweight + comorbidity

The clinical trial (HRS9531‑301) enrolled 567 participants, achieving all primary and key secondary endpoints, positioning HRS9531 as a strong contender in the obesity‑drug market.

Global Licensing & Commercial Strategy

In May 2024, Hengrui licensed the global rights (excluding Greater China) to Kailera Therapeutics for the development, production, and commercialization of HRS9531. Key terms:

  • Upfront Payment + Milestones – Totaling > $6 B.
  • Equity – Hengrui acquired a 19.9 % stake in Kailera.
  • Exclusivity – Kailera holds exclusive rights outside China, ensuring a focused global rollout.

Implications for the Market

  • Competitive Edge – The dual‑agonist mechanism offers a differentiated profile versus existing GLP‑1 monotherapies.
  • Growth Potential – With 44.4 % of high‑dose patients losing ≥20 % of body weight, HRS9531 could capture a sizable share of the obesity‑treatment segment.
  • Strategic Partnership – The $6 B milestone package underscores investor confidence and provides a robust pipeline for Kailera.-Fineline Info & Tech
