Frequently asked questions about TVB-2640

What is TVB-2640 used for?

TVB-2640 is an investigational small molecule being studied for MASLD/MASH, solid malignant tumors, KRAS gene mutation, and non-alcoholic steatohepatitis. It is in clinical development for these conditions, including a Phase 1 study in solid tumors and Phase 2 studies in KRAS non-small cell lung carcinomas and NASH.

What does TVB-2640 target?

TVB-2640 targets FASN, an enzyme involved in fatty acid synthesis. By inhibiting FASN, the drug aims to affect metabolic pathways relevant to diseases like MASH and certain cancers. This mechanism is being evaluated in clinical trials for solid tumors, KRAS-mutant lung cancer, and non-alcoholic steatohepatitis.

Who makes TVB-2640?

TVB-2640 is being developed by Sagimet Biosciences Inc., a company listed on the stock exchange under the ticker SGMT. The company is conducting clinical trials for this investigational drug across multiple indications, including MASH and solid tumors.

What phase is TVB-2640 in?

TVB-2640 is in Phase 1 and Phase 2 clinical trials. It has completed Phase 1 studies in solid tumors and hepatic impairment, and Phase 2 studies in KRAS non-small cell lung carcinomas and non-alcoholic steatohepatitis. It is investigational and not yet approved by the FDA.

What clinical trials is TVB-2640 in?

TVB-2640 has been studied in several clinical trials, including NCT02223247 (Phase 1 in solid tumors), NCT03808558 (Phase 2 in KRAS non-small cell lung carcinomas), NCT03938246 (Phase 2 in NASH), and NCT05835180 (Phase 1 in hepatic impairment). These trials are completed or active.

Is TVB-2640 the same as Denifanstat?

Yes, TVB-2640 is also known as Denifanstat. The drug is referred to by both names in clinical research, including in a Phase 1 pharmacokinetic study of TVB-2640 (Denifanstat) in subjects with hepatic impairment.
