Business Overview and History
Sagimet Biosciences Inc. (NASDAQ:SGMT) is a clinical-stage biopharmaceutical company that has emerged as a key player in the development of novel therapeutics targeting dysfunctional metabolic and fibrotic pathways. With a focus on addressing the growing global epidemic of metabolic dysfunction-associated steatohepatitis (MASH), formerly known as non-alcoholic steatohepatitis (NASH), Sagimet has made significant strides in advancing its lead drug candidate, denifanstat, through the clinical trial process.
Sagimet Biosciences was founded in December 2006 and is headquartered in San Mateo, California. The company was originally incorporated under the name 3-V Biosciences, Inc. before changing its name to Sagimet Biosciences Inc. in August 2019. Sagimet's core focus has been on the development of fatty acid synthase (FASN) inhibitors, a unique approach to targeting the underlying drivers of MASH. These FASN inhibitors are designed to target dysfunctional metabolic and fibrotic pathways in diseases resulting from the overproduction of the fatty acid, palmitate.
The company's journey began with the discovery and optimization of its proprietary FASN inhibitor library, culminating in the selection of denifanstat as the lead candidate for clinical development. Denifanstat is an oral, once-daily FASN inhibitor that has shown promise in clinical trials for the treatment of MASH.

Denifanstat's Clinical Progression and Regulatory Milestones
Sagimet's lead drug candidate, denifanstat, has made significant strides in its clinical development for the treatment of MASH. The positive results from the Phase 2b FASCINATE-2 trial, announced in January 2024, demonstrated the compound's ability to achieve statistically significant improvements in MASH resolution, fibrosis, and liver fat reduction compared to placebo.
In the FASCINATE-2 trial, which evaluated 168 biopsy-confirmed MASH patients with stage F2 or F3 fibrosis, denifanstat achieved primary endpoints including a 2-point reduction in NAFLD Activity Score (NAS) without worsening of fibrosis (52% vs. 20% for placebo, p=0.0003) and MASH resolution without worsening of fibrosis with a 2-point reduction in NAS (36% vs. 13% for placebo, p=0.0044). Additionally, 41% of patients achieved a 1-stage improvement in fibrosis with no worsening of MASH compared to 18% in the placebo group (p=0.0102).
These compelling results paved the way for Sagimet to receive Breakthrough Therapy designation from the FDA for denifanstat in the treatment of non-cirrhotic MASH with moderate to advanced liver fibrosis. This designation is intended to expedite the development and review of drugs that target serious or life-threatening conditions and demonstrate the potential for substantial improvement over existing therapies.
Building on this momentum, Sagimet has initiated a pivotal Phase 3 program for denifanstat in MASH, which is expected to commence patient screening in the first half of 2025.
