Verastem Oncology Advances Treatment Options with VS-7375

Verastem Oncology's Strategic Move with VS-7375

Verastem Oncology (Nasdaq: VSTM) has recently made a significant advancement in its commitment to developing innovative treatments for RAS/MAPK pathway-driven cancers. This Boston-based biopharmaceutical company has exercised its option early to license VS-7375 from GenFleet Therapeutics. VS-7375, also known as GFH375, is an oral inhibitor targeting the KRAS G12D mutation, one of the most prevalent KRAS mutations found in various cancers.

Preliminary Clinical Data from Phase 1 Studies

The Phase 1 dose-escalation study in China has already treated 26 patients with VS-7375, producing both confirmed and unconfirmed partial responses in individuals suffering from advanced non-small cell lung cancer and metastatic pancreatic cancer. Impressively, six dose cohorts have been successfully cleared without any dose-limiting toxicities noted. These encouraging preliminary findings highlight VS-7375's potential as a groundbreaking treatment for patients facing these serious conditions.

Patient Monitoring and Dosing Results

The ongoing study has shown that the oral administration of VS-7375 reaches plasma levels associated with effective responses seen in earlier testing. Notably, these results align with preclinical findings, which reported significant tumor regressions in KRAS G12D tumor models. Verastem anticipates filing a U.S. investigational new drug (IND) application for VS-7375 in early 2025, aiming to commence a Phase 1/2a study shortly thereafter.

The Role of KRAS G12D Mutation in Cancers

Understanding the KRAS G12D mutation's broad implications in cancer is crucial. This mutation accounts for about 26% of all KRAS mutations and is most commonly found in pancreatic cancer (37%), colorectal cancer (12.5%), endometrial cancer (8%), and non-small cell lung cancer (5%). While current treatment options remain limited—with no existing FDA-approved therapies targeting KRAS G12D—the need for effective solutions is clear.

Collaboration with GenFleet Therapeutics

The collaboration with GenFleet Therapeutics is a part of Verastem's strategic approach to tackle RAS pathway-driven cancers. Established in 2023, this partnership not only provides a foundation for risk-sharing but also allows Verastem to exclusively license up to three candidate compounds based on preclinical and clinical milestones. The successful acquisition of VS-7375 marks the first major step in this collaboration, emphasizing the mutual commitment to transforming cancer care.
