Evaluating Drug Concentration and Pharmacodynamics of Niraparib in Patients with Recurrent IDH1/2 Mutated Gliomas

Trial Status: closed to accrual

This phase 0 trial evaluates the intratumoral concentration, activity and effects of niraparib tosylate monohydrate in subjects with IDH1 and/or IDH2 mutated gliomas that have come back (recurrent). Niraparib tosylate monohydrate is a drug that binds to and inhibits an enzyme involved in deoxyribonucleic acid (DNA) repair called poly (adenosine diphosphate [ADP]-ribose) polymerase 1 (PARP), resulting in cell death. Tumors with IDH mutations have been shown to be especially sensitive to PARP inhibitors, and glioma cells that have these types of mutations may possess a reduced capacity to repair DNA, leading to enhanced tumor cell death when exposed to treatment. This trial explores the activity of the PARP inhibitor niraparib tosylate monohydrate in patients with IDH1 and/or IDH2 mutated recurrent gliomas.
