NCT ID NCT07213609

First seen Jun 25, 2026 · Last updated Jul 22, 2026 · Updated 3 times

Summary

This study tests an experimental oral drug, GSK5460025, alone or with other cancer drugs, in adults whose solid tumors have specific genetic changes (dMMR or MSI-H). The goal is to see if the drug can shrink tumors and to check its safety. About 47 people with advanced cancers that have not responded to other treatments will take part.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
GSK5460025 (an oral drug)
What this could lead to
If it works, this could point toward a new treatment option for people with hard-to-treat cancers that have specific genetic features.
What could go wrong
This is an early-phase trial with only 47 participants, so it is not yet known if the drug is effective or safe in larger groups. Side effects and lack of tumor shrinkage are possible.
