HGG-42. PEDIATRIC H3K27M MUTANT DIFFUSE INTRINSIC PONTINE GLIOMA (DIPG) SHOWS ROBUST RESPONSE TO IMIPRIDONE BASED COMBINATION THERAPY

ONC201 is a first-in-class small molecule imipridone therapy, which is known to selectively induce apoptosis of cancer cells independent of p53. This novel chemotherapeutic, as well as its analogs ONC206 and ONC212, has been shown to have potent preclinical efficacy against H3K27M mutant diffuse intrinsic pontine glioma (DIPG). We sought to identify synergy between imipridones and other FDA-approved chemotherapeutics. Seven patient-derived DIPG...
