Trial of Niraparib in Participants With Newly-diagnosed Glioblastoma and Recurrent Glioma

This is an open-label, multi-center Phase 0 study with an expansion phase that will enroll up to 24 participants with newly-diagnosed glioblastoma and up to 18 recurrent glioma participants with IDH mutation and ATRX loss. The trial will be composed of a Phase 0 component (subdivided into Arm A and B) and a therapeutic expansion phase.

Patients with tumors demonstrating a positive PK Response (in Arm A) or a positive PD Response (in Arm B) of the Phase 0 component of the study will graduate to a therapeutic expansion phase that combines therapeutic dosing of niraparib plus standard-of-care fractionated radiotherapy (in Arm A) or niraparib monotherapy (in Arm B) until progression of disease.
