The United Laboratories International Holdings Limited (3933) announced the completion of its Phase II clinical trial for UBT251 Injection in participants with overweight or obesity. According to the announcement, the trial enrolled 205 patients with a baseline mean body weight of 92.20 kg and a baseline mean BMI of 33.10 kg/m². The study was a randomized, double-blind, parallel, placebo-controlled design, with patients assigned to either placebo or UBT251 Injection in various dose groups over 24 weeks.
Results showed that the maximum mean body weight reduction reached 19.70% (17.50 kg) in the UBT251 groups, compared to 2.00% (1.60 kg) in the placebo group. The announcement also noted significant improvements in secondary endpoints such as waist circumference, blood glucose, blood pressure, and blood lipids. The tolerability profile was generally favorable, with the most common adverse events being mild to moderate gastrointestinal reactions.
The company intends to advance UBT251 to Phase III clinical trials for overweight/obesity in China. UBT251 is a triple-target receptor agonist of GLP-1, GIP, and GCG, approved for clinical research in multiple indications including type 2 diabetes, overweight/obesity, chronic kidney disease, and metabolic dysfunction-associated steatohepatitis. Additionally, an exclusive license agreement for UBT251 was signed in March 2025 between United Biotechnology, a subsidiary of The United Laboratories, and Novo Nordisk A/S.
