New hope for rare stomach cancer: drug combo targets tough mutations
NCT ID NCT05734105
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two drugs, ripretinib and sunitinib, in people with advanced gastrointestinal stromal tumors (GIST) that have specific genetic changes (KIT exon 11 plus 17/18 mutations) and have stopped responding to the first treatment, imatinib. About 54 participants will be randomly assigned to receive either ripretinib or sunitinib to see which one better delays cancer growth. If the cancer worsens on sunitinib, those patients may switch to ripretinib.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ripretinib (QINLOCK) and Sunitinib (Sutent)
- What this could lead to
- If ripretinib works better than sunitinib, it could become a new standard second-line treatment for people with this specific type of advanced GIST.
- What could go wrong
- This is a relatively small Phase 3 trial (54 participants) and results may not apply to all GIST patients. There is no guarantee ripretinib will prove superior or be approved for this use.
