A Study Comparing Niraparib With Temozolomide in Adult Participants With Newly-diagnosed, MGMT Unmethylated Glioblastoma
United States, Australia, Canada450 participantsStarted 2024-06-19
Plain-language 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

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 1\. Histologic documentation of a newly-diagnosed intracranial GBM, per 2021 WHO classification guidelines through local pathology review.
* 2\. Age ≥18 years at the time of signing informed consent.
* 3\. Sufficient tissue available for retrospective central pathology review, retrospective central confirmation of MGMT promoter methylation status and genomic analysis. If insufficient tissue is available,pproval may be granted on a case-by-case basis after a review.
* 4\. Unmethylated MGMT promoter region determined locally by a validated PSQ or qMS-PCR assay compliant to local regulations. Numerical cut-off for an MGMT unmethylated tumor will be defined in the protocol.
* 5\. Suitability for SOC RT to 60 Gy in 30 fractions using ESTRO-EANO 'single phase' targeting approach \[Niyazi, 2023\], per investigator's judgment.
* 6\. No prior treatment for GBM (including brachytherapy or BCNU wafers), other than surgical resection or biopsy.
* 7\. Female participants: Not pregnant, planning to get pregnant, or breastfeeding and one of the following conditions apply: is of nonchildbearing potential or is of childbearing potential AND using a contraceptive method that is highly effective (with a failure rate of \<1% per year) from screening through at least 180 days after the last dose of study intervention. Breastfeeding is contraindicated during the study and for one month after the last dose of study intervention.
* 8\. Male participants: Must agree to the foll…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
