First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests a new drug, pimitespib (TAS-116), combined with the standard drug imatinib in people with advanced gastrointestinal stromal tumors (GIST) that have stopped responding to imatinib. The study aims to find the safest dose, check for side effects, and see if the combination can slow tumor growth. About 78 participants will be enrolled across different treatment groups.

What this could mean

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

Active substance

pimitespib (TAS-116) and imatinib

What this could lead to

If successful, this combination could offer a new treatment option for people with GIST whose cancer has stopped responding to imatinib alone.

What could go wrong

This is an early Phase 1 trial with a small number of participants, so it is not yet clear if the combination is safe or effective. Side effects from the drugs may also limit their use.
