United Laboratories International Holdings Ltd (HKG: 3933) announced completion of a Phase II clinical trial for UBT251 Injection, its Category 1 innovative triple‑target agonist, in Chinese patients with overweight/obesity. The study demonstrated significant weight‑loss efficacy across all dose groups, with the maximum mean body weight reduction of -19.7% (-17.5 kg) at Week 24, positioning UBT251 as a potential competitor in the rapidly expanding metabolic disease market.

Strategic Implications
Triple‑Target Differentiation: UBT251’s GLP‑1/GIP/GCG triple agonism offers potential superior efficacy vs. dual agonists (tirzepatide) and single‑target GLP‑1s (semaglutide), with glucagon component adding energy expenditure benefits.
Blockbuster Validation: The 19.7% weight reduction approaches surgical intervention levels and exceeds many approved/investigational pharmacotherapies, supporting USD 2B partnership valuation with Novo Nordisk.
Safety Advantage:Zero discontinuations due to adverse events differentiates UBT251 in a class where GI tolerability is a key commercial consideration.
Pipeline Breadth: Indications spanning obesity, T2D, CKD, and MASH position UBT251 as a multi‑indication metabolic platform with potential to address interconnected disease burden.
