New pill targets Hard-to-Treat cancer mutation in early trial
NCT ID NCT05009329
First seen Jun 25, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This study tests an experimental oral drug called JAB-21822 (glecirasib) in people with advanced solid tumors that have a specific mutation in the KRAS gene (G12C). The trial aims to find the best dose and check if the drug is safe and can shrink tumors. About 315 adults whose cancer has not responded to standard treatments are participating.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JAB-21822 (glecirasib), an oral drug that targets a specific cancer-driving mutation (KRAS G12C)
- What this could lead to
- If successful, this could provide a new treatment option for people with advanced cancers that have a KRAS G12C mutation, especially when other treatments have stopped working.
- What could go wrong
- This is an early-phase trial (Phase 1/2) with a small number of participants, so the drug may not prove effective or safe enough for wider use. Side effects are possible and not yet fully known.
