BioAge Labs (BIOA) has announced the discontinuation of its STRIDES Phase 2 clinical trial evaluating azelaprag in combination with tirzepatide for obesity treatment. The decision follows observations of liver transaminitis in some subjects receiving azelaprag, though without clinically significant symptoms. The study, which enrolled 204 subjects, was designed to evaluate two oral doses of azelaprag combined with tirzepatide in individuals aged 55 and older with obesity.
The company will analyze available data from enrolled subjects and plans to share updated plans for azelaprag in Q1 2025. In parallel, BioAge continues advancing its pipeline, including a brain-penetrant NLRP3 inhibitor program targeting neuroinflammation, with IND submission anticipated in second half of 2025.
