A Study Comparing Niraparib With Temozolomide in Adult Participants With Newly-diagnosed, MGMT Unmethylated Glioblastoma

Summary

The goal of this Phase 3 clinical trial is to compare the efficacy of niraparib versus temozolomide (TMZ) in adult participants with newly-diagnosed, MGMT unmethylated glioblastoma multiforme (GBM). The main question it aims to answer is: Does niraparib improve overall survival (OS) compared to TMZ? Participants will be randomly assigned to one of two treatment arms: niraparib or TMZ. * study drug (Niraparib) or * comparator drug (Temozolomide - which is the standard approved treatment for MGMT unmethylated glioblastoma). The study medication will be taken daily while receiving standard of care radiation therapy (RT) for 6-7 weeks. Participants may continue to take the niraparib or TMZ adjuvantly as long as the cancer does not get worse or completion of 6 cycles of treatment (TMZ). A total of 450 participants will be enrolled in the study. Participants' tasks will include: * Complete study visits as scheduled * Complete a diary to record study medication
