Evidence Type(s): Oncogenic, Functional, Predictive

Justification: Oncogenic: The KIT V559D mutation is described as the most prevalent primary gain-of-function mutation in Gastrointestinal Stromal Tumors (GISTs), indicating its role in tumorigenesis. Functional: The study demonstrates that CHMFL-KIT-031 selectively inhibits the proliferation and auto-phosphorylation of cells expressing the KIT V559D mutation, confirming its functional impact on mutant KIT signaling pathways. Predictive: The selectivity of CHMFL-KIT-031 for the KIT V559D mutation over other mutations and wild-type KIT suggests its potential as a predictive biomarker for treatment response in patients with GISTs harboring this specific mutation.
