Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Niraparib
Treatment: Drugs - Temozolomide

Experimental: Arm A: Niraparib -

Active comparator: Arm B: Temozolomide -


Treatment: Drugs: Niraparib
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

Treatment: Drugs: Temozolomide
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.

* 2. Age =18 years at the time of signing informed consent.
* 3. Sufficient tissue available for retrospective central pathology review and genomic analysis. If insufficient tissue is available, approval 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 laboratory manual.
* 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 following during the study intervention period and for at least 90 days after the last dose of study intervention: refrain from donation sperm PLUS be abstinent from heterosexual activity or agree to use a male condom and be advised of the benefit for a female partner to use a contraceptive method that is highly effective (with a failure rate of <1% per year).
* 9. The participant must be capable of providing signed informed consent, including compliance with the requirements and restrictions listed in the ICF and in this protocol.

* 17. Received a live vaccine within 30 days before the planned start of study intervention. Coronavirus disease 2019 (COVID-19) vaccines that do not contain live viruses are allowed. Note: mRNA and adenoviral-based COVID-19 vaccines are considered non-live.
* 18. Received a transfusion (platelets or red blood cells) or colony-stimulating factors (e.g., granulocyte macrophage colony-stimulating factor or recombinant erythropoietin) within 4 weeks of the planned start of study intervention.
* 19. Treatment with another investigational drug or other intervention within 5 half-lives of the investigational product.
* 20. Treatment with tumor treating fields (e.g., Optune) for GBM.
* 21. Presence of known isocitrate dehydrogenase (IDH) mutation.
* 22. Presence of known H3 mutation.
