TVB-2640: A Promising Drug Candidate in Multiple Therapeutic Areas

Last updated: December 30, 2024

Introduction

TVB-2640, also known as denifanstat, is a small-molecule inhibitor of the fatty acid synthase (FASN) enzyme, which has been gaining significant attention in the pharmaceutical industry for its potential in treating various diseases, including cancer and nonalcoholic steatohepatitis (NASH). Here, we will delve into the development updates and market projections for this promising drug candidate.

Mechanism of Action and Therapeutic Targets

TVB-2640 is a potent and reversible inhibitor of the ketoacylreductase (KR) enzymatic activity of the FASN enzyme. FASN is crucial for the synthesis of long-chain fatty acids, which are essential for cell membrane formation and energy storage. In cancer cells, FASN is often overexpressed, making it a viable therapeutic target. TVB-2640 has shown efficacy in inhibiting lipogenesis and demonstrating target engagement in clinical studies[3].

Clinical Development in Cancer

Phase I and Phase II Studies

In the first-in-human study, TVB-2640 demonstrated a favorable safety profile with predictable pharmacokinetics and manageable side effects. The study established the recommended phase 2 dose (RP2D) of 100 mg/m². When combined with paclitaxel, TVB-2640 showed a disease control rate (DCR) of 70% and partial response rates in patients with KRAS-mutant non-small cell lung cancer (NSCLC), ovarian cancer, and breast cancer[3].

A phase II study in patients with relapsed high-grade astrocytoma showed that TVB-2640, when combined with bevacizumab, had a well-tolerated safety profile and significant clinical activity. The overall response rate (ORR) was 56%, with a progression-free survival rate at 6 months (PFS6) of 31.4%, which was statistically significant compared to historical bevacizumab monotherapy[1].

Ongoing and Future Studies

TVB-2640 is currently being evaluated in several ongoing clinical trials for various types of cancer, including NSCLC, breast, ovarian, prostate, colon, and pancreatic cancer. The favorable safety profile and response signals from earlier studies support the initiation of larger multicenter trials, including a potential phase III study in astrocytoma[1][3].

Clinical Development in NASH

Phase II Studies

In the context of NASH, TVB-2640 has shown promising results. The FASCINATE-1 phase II trial, a randomized, placebo-controlled study of 99 patients in the United States, demonstrated that TVB-2640 significantly reduced liver fat, with a 61% responder rate in the 50 mg group. Participants also showed improvements in markers of liver function and fibrosis. The drug was well-tolerated, with predominantly grade 1 adverse events and no on-treatment serious adverse events[5].

Bridging Studies and Future Plans

A pharmacokinetic bridging study in China confirmed that TVB-2640 has linear pharmacokinetics and is safe and well-tolerated in Chinese subjects, consistent with findings in the United States. This study supports the global development of TVB-2640 for NASH[5].

Sagimet Biosciences, the developer of TVB-2640, plans to hold an end-of-phase 2 meeting with the FDA and aims to start a phase 3 program in the second half of 2024. Given the positive results, TVB-2640 is expected to be a significant player in the NASH market, which is projected to grow substantially due to the launch of novel therapies[4].

Market Projections

NASH Market

The NASH market is anticipated to experience significant growth, driven by the expected launch of novel emerging therapies. TVB-2640, with its favorable safety profile and efficacy in reducing liver fat and improving liver function, is poised to capture a substantial share of this growing market. The United States is expected to be the largest market for NASH treatments, followed by the EU5 countries and Japan[2].

Cancer Market

In the oncology sector, TVB-2640’s potential in treating various types of cancer, particularly those with KRAS mutations, positions it as a promising candidate. The market for cancer therapies is vast and continuously evolving, with a high demand for effective and safe treatments. TVB-2640’s ability to overcome resistance to existing therapies, such as bevacizumab, makes it an attractive option for patients and healthcare providers[1][3].

Safety and Tolerability

Across various studies, TVB-2640 has consistently demonstrated a favorable safety profile. The most frequently reported adverse events are non-serious and reversible, affecting the skin and eyes. In both cancer and NASH studies, TVB-2640 has shown a benign adverse event profile, predominantly consisting of grade 1 events[1][3][5].

Conclusion

TVB-2640 is a highly selective FASN inhibitor with significant potential in treating both cancer and NASH. Its favorable safety profile, combined with its clinical efficacy, makes it a promising drug candidate. As it progresses through clinical trials and potentially moves towards regulatory approval, TVB-2640 is expected to play a crucial role in the treatment of these diseases, contributing to the growth of the respective markets.
