This federal Project Grant award from the National Cancer Institute (NCI) under the Cancer Treatment Research program (CFDA 93.395) provides funding to the University of California, San Diego (UCSD) to investigate novel therapeutic approaches for treating gastrointestinal stromal tumors (GIST) driven by KIT mutations. The $662,682 award, effective June 4, 2025 through May 31, 2030, will support a Phase 1 clinical trial to assess the safety and efficacy of combining the tyrosine kinase inhibitor imatinib with the potassium channel blocker 4-AP to target both sensitive and resistant GIST tumor cells. The project aims to validate KVB1.1 protein or KCNAB1 mRNA expression as predictive biomarkers of treatment response, and study how modulating voltage-gated potassium channels impacts GIST cell biology and tumor aggressiveness. This multi-disciplinary effort unites UCSD experts in GIST oncology, clinical trials, radiology, pathology, computational biology, and potassium channel biology to drive improvements in outcomes for patients with KIT-mutant GIST.
