Insights
Sagimet's acne drug denifanstat achieved all Phase 3 endpoints with strong efficacy data, validating their novel FASN inhibition approach.
Sagimet's announcement represents a significant clinical milestone for their fatty acid synthase (FASN) inhibitor platform. The Phase 3 trial for denifanstat in moderate to severe acne demonstrated robust efficacy with a
What makes this particularly notable is that denifanstat represents a novel mechanism of action in a therapeutic area that has seen limited innovation in four decades. The once-daily oral administration also offers a potential advantage over topical treatments that dominate the acne market.
This validates Sagimet's scientific approach targeting FASN inhibition while simultaneously strengthening their partnership with Ascletis, who holds rights to the compound in China. The positive safety profile noted ("generally well-tolerated") is equally important for regulatory consideration, especially for a chronic condition like acne.
Strategically, Sagimet is expanding their FASN inhibitor pipeline with TVB-3567 now in Phase 1, suggesting confidence in the mechanism beyond just denifanstat. While the company is developing denifanstat for MASH (Metabolic dysfunction-Associated SteatoHepatitis) outside China, these acne results demonstrate the platform's potential versatility across multiple indications.
Denifanstat met all primary and secondary endpoints versus placebo
Denifanstat was generally well tolerated
Sagimet initiated first-in-human Phase 1 clinical trial of a second FASN inhibitor, TVB-3567, for development in acne
SAN MATEO, Calif., Sept. 17, 2025 (GLOBE NEWSWIRE) -- Sagimet Biosciences Inc. (Nasdaq: SGMT), a clinical-stage biopharmaceutical company developing novel therapeutics targeting dysfunctional metabolic and fibrotic pathways, today reported that data from a Phase 3 clinical trial for the treatment of moderate to severe acne vulgaris conducted by Sagimet’s license partner Ascletis Bioscience Co. Ltd. (Ascletis) will be presented at the European Academy of Dermatology and Venerology (EADV) 2025 Congress taking place September 17-20, 2025 in Paris, France. Denifanstat is a once-daily oral small molecule fatty acid synthase (FASN) inhibitor being developed by Ascletis as ASC40 for acne in China and by Sagimet for MASH in the rest of world.
The Phase 3 clinical trial was a randomized, double-blind, placebo-controlled, multicenter clinical trial in China to evaluate the safety and efficacy of denifanstat for the treatment of patients with moderate to severe acne, defined as Investigator’s Global Assessment (IGA) scores of 3 and 4. This trial enrolled 480 patients who were randomized 1:1 into two treatment arms to receive denifanstat 50mg or placebo, once daily for 12 weeks. Primary endpoints included the percentage of treatment success (defined as an IGA score of 0 (clear) or 1 (almost clear) with at least a 2-point decrease from baseline), the percentage change in total lesion count, and the percentage change in inflammatory lesion count. Denifanstat met all primary and secondary endpoints and was generally well tolerated.

“FASN inhibition represents a novel mechanism of action for the treatment of acne, a condition that impacts more than 50 million people in the U.S. annually, with limited innovation over the last 40 years,” said David Happel, Chief Executive Officer of Sagimet. “While Ascletis continues to advance denifanstat for approval in China, Sagimet initiated a Phase 1 first-in-human clinical trial with a second FASN inhibitor, TVB-3567, that we plan to develop as a novel therapeutic option for patients with moderate to severe acne.”
About Sagimet Biosciences
Sagimet is a clinical-stage biopharmaceutical company developing novel fatty acid synthase (FASN) inhibitors that are designed to target dysfunctional metabolic and fibrotic pathways in diseases resulting from the overproduction of the fatty acid, palmitate. Sagimet’s lead drug candidate, denifanstat, is an oral, once-daily pill and selective FASN inhibitor in development for the treatment of metabolic dysfunction associated steatohepatitis (MASH). FASCINATE-2, a Phase 2b clinical trial of denifanstat in MASH with liver biopsy-based primary endpoints, was successfully completed with positive results. Denifanstat has been granted Breakthrough Therapy designation by the FDA for the treatment of non-cirrhotic MASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis), and end-of-Phase 2 interactions with the FDA have been successfully completed, supporting the advancement of denifanstat into further development. Sagimet has recently initiated a Phase 1 first-in-human clinical trial with a second oral FASN inhibitor drug candidate, TVB-3567, that is planned to be developed for acne in the U.S. For additional information about Sagimet, please visit www.sagimet.com.
About Acne
There are 5.1 million acne patients treated by dermatologists annually in the U.S., and a total U.S. acne market of over 50 million people.1,2 There is no cure for acne; and due to its pathology, most patients require chronic management and multiple courses of treatment for flare control annually. Additionally, adherence to topical therapies is lower than with oral agents, with an estimated
