Sagimet Biosciences Inc., a clinical-stage biopharmaceutical company, announced the positive results of a Phase 3 clinical trial conducted by its license partner, Ascletis Bioscience Co. Ltd. in China, for the treatment of moderate to severe acne vulgaris. The trial evaluated the oral small molecule fatty acid synthase (FASN) inhibitor, denifanstat, which met all primary and secondary endpoints versus a placebo and was well tolerated by participants. This development marks an advancement in acne treatment, introducing a novel mechanism of action through FASN inhibition. Additionally, Sagimet has initiated a Phase 1 clinical trial in the United States for a second FASN inhibitor, TVB-3567, targeting acne treatment. The positive outcomes from the trial underscore the potential of FASN inhibition as a therapeutic approach for acne.
