KIT T670I | gastrointestinal stromal tumor | predicted - resistant | Avapritinib | Phase I | Actionable | In a Phase I trial, patients with gastrointestinal stromal tumors harboring either KIT V654A or KIT T670I demonstrated decreased overall response rate (0%, 0/25 vs. 26%, 22/84) and increased progressive disease rate (72% vs 23%) compared to those without either KIT mutation when treated with Ayvakit (avapritinib) (PMID: 31270078; NCT02508532). | 31270078 |
