New pill targets stubborn colorectal cancer mutation
NCT ID NCT07659795
First seen Jun 27, 2026 · Last updated Sep 17, 2026 · Updated 19 times
Summary
This study tests an experimental pill called VS-7375, designed to block a specific cancer-driving protein (KRAS G12D). The trial includes people with metastatic colorectal cancer that has this mutation. Some participants receive VS-7375 alone, others get it combined with an antibody therapy or with antibody therapy plus chemotherapy. The goal is to see if these combinations can shrink tumors and control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VS-7375
- What this could lead to
- If successful, this could provide a new targeted treatment option for people with a hard-to-treat form of colorectal cancer that has spread.
- What could go wrong
- This is an early-phase trial with a small number of participants, so the drug may not work as hoped or could cause significant side effects. Results may not apply to all patients.
Why investors are watching
Verastem is a very small company, so this phase 2 trial of its oral drug VS-7375 in metastatic colorectal cancer is a major test. The trial checks whether the drug works alone, with an EGFR antibody, or with the antibody plus chemotherapy. A clear result matters because this drug targets a specific KRAS mutation, and the company's future depends on showing it helps patients.
If it works: A positive result could show that VS-7375 controls the disease in a hard-to-treat cancer, which might lead to further development and partnerships. For a micro-cap company, a successful readout could be a turning point that validates its main drug candidate.
If it fails: Trials often fail, and this one could show the drug is unsafe or does not shrink tumors. A failure or delay would be a serious setback for Verastem, possibly limiting its ability to raise money or continue the program.
