Sagimet Biosciences Inc. (Nasdaq: SGMT) announced strategic updates on April 27, 2026, outlining its clinical development timeline for denifanstat, a potential breakthrough treatment for moderate to severe acne.

Phase 3 Acne Trial Timeline

The San Mateo-based clinical-stage biopharmaceutical company plans to launch its pivotal Phase 3 clinical trial of denifanstat in the second half of 2026. This represents a significant milestone for patients suffering from moderate to severe acne, a condition affecting millions of Americans and representing a substantial unmet medical need.
