About this study
Official title: A Phase 3, Open-label, Randomized 2-arm Study Comparing the Clinical Efficacy and Safety of Niraparib With Temozolomide in Adult Participants With Newly-diagnosed, MGMT Unmethylated Glioblastoma
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?
Read more
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
- Conditions
- Glioblastoma, GBM, Brain Neoplasms, Adult, Malignant, Brain Tumor
- Being tested
- Niraparib, Temozolomide
- Medical subject headings
- Glioblastoma, Brain Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NiraparibDrug
Also called Zejula
Participants will receive niraparib 200 mg orally once daily starting on Day 1 of RT. Following completion of RT, participants will continue niraparib adjuvant therapy orally once daily on Days 1 to 28 of each 28-day cycle until progression by BICR
TemozolomideDrug
Also called Temodar, TMZ
Participants randomized to the comparator arm (Arm B) will receive SOC TMZ 75 mg/m2 orally once daily with RT starting on Day 1 of RT. Following completion of RT, participants will complete a 4-week rest period, and then receive adjuvant TMZ 150 to 200 mg/m2 orally once daily on Days 1 to 5 of each 28-day cycle until progression by BICR or for a maximum of 6 cycles.
| Study group | Role | What they receive |
|---|---|---|
| Arm A: Niraparib | Experimental | Not described Receives: Drug: Niraparib |
| Arm B: Temozolomide | Active comparator | Not described Receives: Drug: Temozolomide |
What is being measured

Changes from baseline in neurocognitive function assessed by Trail Making Test Parts A and B
The Trail Making Test Part A is designed to evaluate visual motor scanning speed, and the Trail Making Test Part B is designed to evaluate executive function. These tests require participants to connect circles in numerical (Part A) or alternating numerical and alphabetical sequence (Part B) within a timed interval of less than 5 minutes for each test.
Measured: on Day 1 pre-dose or up to 7 days prior, on any day during the 6th week of RT, and on days of MRI at 4- and 12- weeks after RT, every 16 weeks thereafter on days of MRI
Incidence of participants with adverse events (AEs), serious adverse events (SAEs) and adverse events of special interest (AESIs)
AEs, SAEs and AESIs will be collected
Measured: 24 months
Incidence of treatment discontinuations, dose interruptions, and dose reductions due to AEs, SAEs, or AESIs, changes in Karnofsky performance status, changes in clinical laboratory results, and vital sign measurements
Treatment discontinuations, dose interruptions, and dose reductions
Measured: 24 months
Frequency and severity of symptomatic AEs based on PRO-CTCAE
The PRO-CTCAE is a patient-reported outcome measure developed to evaluate symptomatic toxicity in patients on cancer clinical trials.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Niraparib and Temozolomide in people with Glioblastoma and GBM, run by Ivy Brain Tumor Center at 95 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 1 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 95 sites in United States, Spain, France, Germany, Italy and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (time frame: 24 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jul 2026.
