First seen Jan 21, 2026 · Last updated Jun 06, 2026 · Updated 27 times

Summary

This early-phase study tests whether the drug regorafenib can help control gastrointestinal stromal tumors (GIST) that have specific genetic changes (KIT exon 17, 18, or 14 mutations, or SDHB deficiency) after imatinib has stopped working. Only 3 adults with measurable, unresectable tumors are enrolled. The main goal is to check safety and side effects.
