• Combination treatment of a FASN inhibitor with semaglutide, a GLP-1 receptor agonist, improved several biomarkers associated with NASH in a mouse model and showed a significant improvement in liver fibrosis, while semaglutide alone did not significantly improve fibrosis
  
• Reductions of circulating lipids associated with cardiovascular risk were observed in denifanstat-treated patients in the FASCINATE-2 Phase 2b clinical trial interim analysis, with numerical separation from placebo at Week 4 and statistically significant responses at Week 13
• FASCINATE-2 Phase 2b clinical trial of denifanstat in F2-F3 NASH patients is fully enrolled; on track to report week 52 topline results, including liver biopsy, in the first quarter of 2024

SAN MATEO, Calif., Nov. 10, 2023 (GLOBE NEWSWIRE) -- Sagimet Biosciences Inc. (Sagimet, Nasdaq: SGMT), a clinical-stage biopharmaceutical company developing novel fatty acid synthase (FASN) inhibitors that target dysfunctional metabolic pathways, today announced the presentation of preclinical results detailing artificial intelligence (AI) based digital pathology of Sagimet’s FASN inhibitor alone or in combination with semaglutide in a preclinical mouse model of nonalcoholic steatohepatitis (NASH). A comprehensive lipidomic analysis from the interim analysis of the FASCINATE-2 Phase 2b clinical trial will also be presented in a late-breaking poster session at the American Association for the Study of Liver Diseases (AASLD) - The Liver Meeting^® 2023 held November 10-14, 2023 in Boston.

“The preclinical combination results underscore the importance of developing disease modifying therapies, such as denifanstat, for NASH patients,” said Marie O’Farrell, Ph.D., Sagimet’s Senior Vice President of Research and Development. “There is a sizeable population of NASH patients with type 2 diabetes. Our data, consistent with published clinical results, suggests that GLP-1 therapy alone is associated with major body weight loss but does not significantly reduce liver fibrosis, a predictor of outcome in NASH. We are pleased that the combination treatment significantly decreased liver fibrosis as well as NAFLD activity score (NAS) in this preclinical model, and believe it could warrant further clinical evaluation. At this time, we are focused on continuing to advance denifanstat as a potential monotherapy and are on track to report topline results of our FASCINATE-2 Phase 2b clinical trial, including biopsy data, in the first quarter of next year.”

Highlights from the posters include:

Poster [2400-C]: Artificial Intelligence Based Digital Pathology Reveals Fatty Acid Synthase (FASN) Inhibitor Alone or in Combination with Semaglutide Improves Fibrosis in Diet-Induced Obese Mice with Biopsy-Confirmed NASH and Fibrosis

In diet-induced obese mice with biopsy confirmed NASH and fibrosis, a combination treatment of Sagimet’s FASN inhibitor with semaglutide, a GLP-1 analogue, significantly decreased ALT, liver triglycerides and cholesterols. A single treatment of a FASN inhibitor or semaglutide - improved the NAFLD activity score, or NAS, (NAS ≥ 1 point, 47% and 56%, respectively). The combination of a FASN inhibitor and semaglutide showed further improvement of NAS (94%, p<0.001). Semaglutide reduced body weight by >20% in NASH mice, alone, or in combination with a FASN inhibitor. The digital AI pathology assessment showed that treatment with a FASN inhibitor alone, or in combination with semaglutide significantly reduced liver fibrosis (p<0.05 and p<0.01, respectively). Treatment with semaglutide alone did not show significant reduction of liver fibrosis. These results support the further clinical evaluation of denifanstat in combination with GLP-1 receptor agonists.

Late-Breaking Poster [5051-C]: Interim Analysis of FASCINATE-2 A Phase 2b Randomized, Placebo Controlled Trial Demonstrated Denifanstat Reduces Circulating Saturated Diacylglycerols and Triacylglycerols, Markers of Lipotoxicity

Lipidomic results demonstrated a beneficial shift in lipid profile for the 52 denifanstat-treated patients assessed in the interim analysis of the FASCINATE-2 Phase 2b clinical trial. Treatment with denifanstat was associated with reduced circulating saturated lipids and ceramides associated with cardiovascular risk such as LDL, tripalmitin and C16-ceramide, with numerical separation from placebo at week 4 and statistically significant responses at week 13. There was also an increase in beneficial unsaturated lipids and polyunsaturated fatty acid (PUFA) content at week 13. These improvements are consistent with the results previously presented at the European Association for the Study of the Liver (EASL) Congress in June 2023 and the FASCINATE-1 Phase 2a clinical trial findings.

Rohit Loomba, M.D., M.H.Sc., Chief, Division of Gastroenterology and Hepatology, Director, MASLD Research Center, University of California San Diego commented, “This comprehensive analysis demonstrates denifanstat’s improvements in the circulating blood lipid profile starting from week 4 of treatment. It is encouraging that the early results are sustained at week 13. The observation that treatment with denifanstat was associated with decreased the di-/triglycerides that are unregulated in NASH and increased cardioprotective polyunsaturated di-/triglycerides, is promising. These results, combined with the previous data from the FASCINATE-1 Phase 2a clinical trial, reinforce the potential of denifanstat to reduce lipotoxic drive and decrease cardiovascular risk in NASH patients.”

Both abstracts are now available on the AASLD website and the presentations are available in the “Posters and Publications” section of Sagimet’s website.

About Sagimet Biosciences

Sagimet is a clinical-stage biopharmaceutical company developing novel fatty acid synthase (FASN) inhibitors that target dysfunctional metabolic 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 NASH, for which there are no treatments currently approved in the United States or Europe. Denifanstat is currently being tested in FASCINATE-2, a Phase 2b clinical trial in NASH with liver biopsy as the primary endpoint.
