(Nasdaq: SGMT), clinical-stage biopharmaceutical company developing novel therapeutics targeting dysfunctional metabolic and fibrotic pathways, today reported financial results for the full year ended December 31, 2024, and provided recent corporate updates. “2024 was a highly productive year for Sagimet, and we’re carrying that momentum into a strong start for 2025,” said David Happel, Chief Executive Officer of Sagimet. “We are pleased to have initiated our Phase 3 denifanstat program in MASH, with site activation and patient pre-screening underway and patient screening expected to begin soon. With the successful Phase 2b FASCINATE-2 results we reported in 2024, and Breakthrough Therapy designation granted by the FDA, we are confident in denifanstat’s potential to address the significant unmet need for patients living with MASH. At the same time, we are excited to advance a second Fatty Acid Synthase inhibitor, TVB-3567, into the clinic for the potential treatment of moderate to severe acne, following IND clearance. Given the potential of FASN inhibition across multiple disease states, we look forward to progressing both denifanstat and TVB-3567 in the coming year.” Full Year and Recent Corporate Highlights Clinical and Regulatory Updates In March 2025, Sagimet announced the clearance of its IND application for a first-in-human Phase 1 clinical trial of a second FASN inhibitor, TVB-3567. The Phase 1 trial initiation is planned in 2025. In October 2024, Sagimet announced the successful completion of end-of-Phase 2 interactions with the FDA, supporting the advancement of denifanstat into Phase 3 development in metabolic-dysfunction associated steatohepatitis (MASH). The planned program will include two Phase 3 trials: FASCINATE-3, evaluating patients with F2/F3 (non-cirrhotic) MASH, and FASCINIT, evaluating patients with suspected or confirmed diagnosis of metabolic dysfunction-associated steatotic liver disease (MASLD)/MASH. In October 2024, Sagimet announced that the FDA granted Breakthrough Therapy designation to denifanstat for the treatment of non-cirrhotic MASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Breakthrough Therapy designation was supported by positive data from the Phase 2b FASCINATE-2 trial in biopsy-confirmed F2/F3 MASH patients and continuing unmet need for differentiated therapies. In January 2024, Sagimet announced positive topline results from the Phase 2b FASCINATE-2 clinical trial, evaluating denifanstat in biopsy-confirmed MASH patients with stage F2 or F3 fibrosis compared to placebo at week 52. The study met its primary efficacy endpoints and multiple secondary endpoints. Full 52-week data from the intention to treat (ITT), modified intention to treat (mITT), and F3 patient population were presented at the European Association for the Study of the Liver (EASL) Congress in June 2024. Publications and Presentations In February 2025, Sagimet delivered an oral presentation at the MASH Pathogenesis and Therapeutic Approaches Keystone Symposium. The presentation featured lipidomic data on improvements in polyunsaturated fatty acid triglycerides and LDL cholesterol levels in advanced fibrosis patients from the Phase 2b FASCINATE-2 trial of denifanstat in MASH, and preclinical data showing reduction of LDL and chemokines in a preclinical atherosclerosis model. In January 2025, Sagimet delivered an oral presentation at the 9th Annual MASH-TAG Conference highlighting the differentiated mechanism of action of the FASN inhibitor denifanstat and the observed anti-fibrotic effect in the Phase 2b FASCINATE-2 study in F2/F3 MASH. In November 2024, Sagimet presented clinical denifanstat and preclinical FASN inhibitor data at the American Association for the Study of Liver Disease (AASLD) - The Liver Meeting 2024®. Phase 2b data demonstrating the anti-fibrotic activity of its FASN inhibitor denifanstat was featured in an oral presentation and poster. In addition, preclinical data demonstrating potential benefit of FASN inhibition in reversing atherosclerosis was presented in a poster. In October 2024, Sagimet announced the publication of results from the Phase 2b FASCINATE-2 clinical trial of denifanstat in The Lancet Gastroenterology & Hepatology. The publication, titled “Denifanstat for the treatment of metabolic-dysfunction associated steatohepatitis: a multicentre, double-blind, randomised, placebo-controlled, phase 2b trial,” reported that denifanstat treatment achieved statistically significant and clinically meaningful improvements in disease activity, MASH resolution and fibrosis. In September 2024, Sagimet delivered an oral presentation at the 8th Annual MASH Drug Development Summit highlighting denifanstat’s direct anti-fibrotic activity in MASH. Corporate Updates Throughout 2024, Sagimet announced several appointments to its board of directors, including industry leaders Tim Walbert, Paul Hoelscher, Dr. Anne Phillips and Jennifer Jarrett. In May 2024, Sagimet appointed Thierry Chauche as Chief Financial Officer. In January 2024, Sagimet completed a follow-on offering of 9,000,000 shares of its Series A common stock, resulting in $104.7 million in net proceeds. Anticipated Upcoming Milestones Start-up activities for the Phase 3 program for denifanstat in MASH have begun, with sites activated and patients pre-screened in the fourth quarter of 2024. Screening of patients is expected to start in the first half of 2025. The Phase 3 program consists of two double-blind, placebo-controlled multicenter registrational trials: FASCINATE-3 in patients with F2/F3 (non-cirrhotic) MASH: The trial is expected to evaluate the efficacy and safety of denifanstat in this population, with primary endpoints being liver biopsy assessments at 52 weeks, at which time Sagimet plans to seek accelerated approval in the US and Europe based on this 52-week data. The trial will continue until such point in time that the required number of clinical outcomes is reached, estimated at 3.5 years after the week 52 timepoint. FASCINIT in patients with suspected or confirmed diagnosis of MASLD/MASH: The trial is expected to evaluate the safety and efficacy of denifanstat in this population, with the primary endpoint of safety and tolerability at 52 weeks. Non-invasive biomarkers will be assessed as part of the secondary endpoints, with no liver biopsy endpoint. The Phase 3 program is designed to comprise a minimum of 1,800 patients exposed to denifanstat. A first-in-human Phase 1 trial of TVB-3567 is anticipated to initiate in 2025. In November 2024, the Company’s license partner for Greater China, Ascletis BioScience Co. Ltd. (Ascletis) announced completion of enrollment of 480 patients in its Phase 3 clinical trial of denifanstat for acne in China, and that it expects to announce topline results in the second quarter of 2025. The Phase 3 trial was initiated following positive Phase 2 acne data reported in Q2 2023. FASCINATE-3 in patients with F2/F3 (non-cirrhotic) MASH: The trial is expected to evaluate the efficacy and safety of denifanstat in this population, with primary endpoints being liver biopsy assessments at 52 weeks, at which time Sagimet plans to seek accelerated approval in the US and Europe based on this 52-week data. The trial will continue until such point in time that the required number of clinical outcomes is reached, estimated at 3.5 years after the week 52 timepoint. FASCINIT in patients with suspected or confirmed diagnosis of MASLD/MASH: The trial is expected to evaluate the safety and efficacy of denifanstat in this population, with the primary endpoint of safety and tolerability at 52 weeks. Non-invasive biomarkers will be assessed as part of the secondary endpoints, with no liver biopsy endpoint. The Phase 3 program is designed to comprise a minimum of 1,800 patients exposed to denifanstat.

About MASH Metabolic-dysfunction associated steatohepatitis (MASH) is a progressive and severe liver disease which is estimated to impact more than 115 million people worldwide, for which there is only one recently approved treatment in the United States and no currently approved treatments in Europe. In 2023, global liver disease medical societies and patient groups formalized the decision to rename non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated steatotic liver disease (MASLD) and nonalcoholic steatohepatitis (NASH) to MASH. Additionally, an overarching term, steatotic liver disease (SLD), was established to capture multiple types of liver diseases associated with fat buildup in the liver. The goal of the name change was to establish an affirmative, non-stigmatizing name and diagnosis.

TVB-3567 is the Company’s second fatty acid synthase (FASN) inhibitor First-in-human Phase 1 trial initiation planned in 2025 SAN MATEO, Calif., March 11, 2025 (GLOBE NEWSWIRE) -- Sagimet Biosciences Inc. (Sagimet, Nasdaq: SGMT), a clinical-stage biopharmaceutical company developing novel therapeutics targeting dysfunctional metabolic and fibrotic pathways, today announced the clearance of its Investigational New Drug (IND) application for TVB-3567, the Company’s second fatty acid synthase (FASN) inhibitor. TVB-3567 is a potent and selective small molecule FASN inhibitor, planned to enter clinical development for the treatment of acne. The IND with the U.S. Food and Drug Administration’s Division of Dermatology and Dentistry allows the Company to initiate a first-in-human Phase 1 clinical trial of TVB-3567, planned in 2025. “The clearance of the TVB-3567 IND marks a significant milestone for Sagimet, as we advance our second FASN inhibitor into the clinic and expand our therapeutic presence into dermatology,” said David Happel, Chief Executive Officer of Sagimet. “FASN inhibition is a highly attractive target in the treatment of acne, addressing acne’s most significant contributor, sebum. We are excited about bringing TVB-3567 into the clinic, building upon compelling data from the denifanstat program in acne, including the favorable sebum lipid composition changes demonstrated in the Phase 1 clinical trial conducted by Sagimet, and the significant decreases in inflammatory and non-inflammatory lesion counts after 12 weeks of treatment shown in a Phase 2 clinical trial conducted by our license partner Ascletis BioScience in patients with moderate to severe acne vulgaris in China. Based on both its mechanism of action and strong preclinical profile, we believe TVB-3567 has the potential to offer a differentiated treatment option for acne. We look forward to initiating enrollment of the first-in-human study of TVB-3567 in 2025.” Over 50 million people suffer from acne in the US, making it one of the most prevalent skin diseases that physicians address annually. Acne’s pathogenesis is highly associated with increased sebum production in the skin. FASN is the last committed step in the de novo lipogenesis pathway which produces approximately 80% of sebum lipids, including the fatty acids palmitate and sapienate. Previous pre-clinical and clinical studies have demonstrated that a FASN inhibitor can favorably alter sebum composition and significantly reduce acne lesions. FASN inhibition therefore represents a therapeutic target within acne and a significant commercial opportunity, if approved. The planned Phase 1 clinical trial will be a randomized double-blind placebo-controlled trial designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of TVB-3567 in healthy participants with or without acne. The trial is expected to be comprised of several parts, including single ascending dose cohorts and multiple ascending dose cohorts in participants without acne, followed by testing in participants with acne including evaluation of pharmacodynamic biomarkers.
