Aug 28

Hong Kong-listed CSPC Pharmaceutical Group Limited (CSPC Pharma) announced on 28 August 2026 that the first study centre in Mainland China has formally activated the Phase II clinical trial (SYH2069-004) of SYH2069 Injection, a novel dual-target therapy for weight management in adults with overweight or obesity.

SYH2069 is a fatty acid-modified polypeptide designed to act as a long-acting dual-biased agonist of the glucagon-like peptide-1 receptor (GLP-1R) and glucose-dependent insulinotropic polypeptide receptor (GIPR). By selectively activating the cyclic adenosine monophosphate (cAMP) pathway while avoiding β-arrestin-mediated receptor desensitisation, the candidate aims to enhance insulin-secretion, suppress appetite, delay gastric emptying, increase satiety and reduce caloric intake, thereby delivering combined glucose-lowering and weight-reducing effects.

Preclinical evaluations indicated favourable target activity and a manageable safety profile. Following receipt of a Clinical Trial Approval from the National Medical Products Administration in December 2025, CSPC Pharma completed Phase I trials that established preliminary safety and pharmacokinetic/pharmacodynamic characteristics in healthy participants with overweight or obesity.

The ongoing Phase II study is structured as a multicentre, randomised, double-blind, placebo-controlled trial focusing on non-diabetic individuals with obesity. Participant recruitment and screening are currently in progress.
