A Phase I-II Study of Niraparib Plus Temozolomide "One Week on, One Week Off" in Patients With Recurrent Isocitrate Dehydrogenase (IDH) Wild Type Glioblastoma and IDH Mutant Gliomas.

Trial ID: NCT06258018

Interventional - Phase 1/2 - Not yet recruiting

The study evaluates safety, tolerability, pharmacokinetics at recommended phase II dose (RP2D) and preliminary antitumor activity of Niraparib + dd-TMZ "one week on, one week off" in patients affected by recurrent GBM IDH wild-type and recurrent IDH mutant (WHO grade 2-4) gliomas. The treatment will be administered until progressive disease, unacceptable toxicity, consent withdrawal, lost to follow-up or death. The entire study is expected to last approximately 40 months.

• 11. Life expectancy \> 12 weeks.
• 12. Ability to swallow intact solid oral dosage form (without chewing, crushing, or opening).
• 13. Normal bone marrow and organ function as defined below:
• Neutrophils ≥ 1500/mm3 Platelets ≥ 150x103/mm3 Hemoglobin ≥ 9.0 g/dL Serum creatinine ≤ 1.5 x the upper limit of normal (ULN) or creatinine clearance (CrCl)≥ 40 mL/min (using the Cockcroft-Gault formula) Aspartate aminotransferase (AST) ≤ 2 x ULN Alanine aminotransferase (ALT) ≤ 2 x ULN Bilirubin≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin \< 3.0 mg/dL)
• 14. international normalized ratio (INR) ≤ 1.5 x ULN
• 15. partial thromboplastin time (PTT) ≤ 1.5 x ULN
• 16. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
• Is not a woman of childbearing potential (WOCBP). or Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of \<1% per year), from the Screening Visit through at least 180 days after the last dose of study treatment and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The Investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study treatment (see also Appendix A).
• A WOCBP must have a negative highly sensitive pregnancy test (urine or serum, as required by local regulations) within 72 hours prior to the first dose of study treatment. (The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy).
• 17. A male participant of reproductive potential is eligible to participate if he agrees to the following starting with the first dose of study treatment through at least 90 days (a spermatogenesis cycle) after the last dose of study treatment:
• refrain from donating sperm plus, either: be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent or must agree to use a male condom and should also be advised of the benefit for a female partner to use a highly effective method of contraception, as a condom may break or leak, when having sexual intercourse with a WOCBP who is not currently pregnant
