Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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 questions it aims to answer are: Does niraparib improve progression-free survival (PFS) compared to TMZ? 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

Accepts Healthy Volunteers:No

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion 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 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. * 10. Karnofsky performance status of ≥70. * 11. Adequate organ function * 12.

Participant is at an increased bleeding risk due to concurrent conditions (e.g., major injuries or major surgery within the past 28 days prior to start of study treatment). * 4. Any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach and/or bowels. * 5. Has cirrhosis or current unstable liver or biliary disease per investigator assessment defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal/gastric varices, or persistent jaundice. NOTE: Stable noncirrhotic chronic liver disease (including Gilbert's syndrome or asymptomatic gallstones), hepatobiliary involvement of malignancy, or chronic stable HBV infection (in a participant for whom HDV infection has been excluded) or chronic HCV infection is acceptable if the participant otherwise meets entry criteria. * 6.

MDS/AML or with features suggestive of MDS/AML. * 8. History of another malignancy within 2 years prior to registration. Participants with a past history of adequately treated carcinoma-in-situ, basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or superficial transitional cell carcinoma of the bladder are eligible.
