UNITED LAB Initiates Phase III Trials of Triple-Agonist UBT251 for Type 2 Diabetes in China

Bulletin Express09-07

The United Laboratories International Holdings Limited (UNITED LAB) announced that the first participant has been dosed in its Phase III clinical programme for UBT251 Injection, a self-developed Class 1 long-acting GLP-1/GIP/GCG triple-agonist targeting type 2 diabetes.

The Phase III programme, conducted by wholly-owned subsidiary The United Bio-Technology (Hengqing) Co., Ltd., comprises two studies:

1. UNIGUIDE-1: A randomized, double-blind, placebo-controlled trial enrolling 360 adults with HbA1c between 7.5 % and 10.5 %. The primary endpoint is change in HbA1c after 40 weeks of treatment.

2. UNIGUIDE-2: A randomized, open-label study comparing UBT251 with semaglutide injection in 956 adults whose HbA1c ranges from 7.5 % to 11.0 % despite metformin and/or sulfonylureas or SGLT2 inhibitors. The primary endpoint is change in HbA1c at week 40, with secondary endpoints covering body weight, blood pressure, lipid profiles and HbA1c at week 52.

UBT251 is the first chemically synthesised long-acting GLP-1R/GIPR/GCGR triple-agonist to enter clinical trials in China and only the second worldwide. Regulatory clearances have been obtained in China and/or the United States for additional indications, including overweight or obesity, chronic kidney disease, metabolic dysfunction-associated steatohepatitis and obstructive sleep apnoea with obesity.

UNITED LAB and United Bio-Technology signed an exclusive licence agreement with Novo Nordisk A/S for UBT251 in March 2025.

The Board, chaired by Mr Tsoi Hoi Shan, released the update on 7 September 2026.
