Study Description

Brief Summary:

The primary objective of this study is to evaluate the safety, efficacy and clinical activity of Pamiparib in combination with radiation therapy (RT) and/or temozolomide (TMZ) in participants with newly diagnosed or recurrent/refractory glioblastoma.

Condition or disease	Intervention/treatment	Phase
Brain and Central Nervous System Tumors	Drug: Pamiparib; Drug: TMZ; Radiation: Radiation	Phase 1; Phase 2

Detailed Description:

An open-label, multiple-dose, dose-escalation study to determine the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of Pamiparib in combination with radiation therapy (RT) and/or TMZ.

In dose escalation/Phase 1b, Pamiparib will be combined with RT (Arm A) or RT and TMZ (Arm B) in participants with newly diagnosed unmethylated glioblastoma (GBM) and in Arm C of the study Pamiparib will be combined with TMZ in participants with methylated or unmethylated recurrent/refractory GBM.

The dose expansion/Phase 2 phase will enroll up to 4 cohorts: participants with newly diagnosed unmethylated GBM in Arms A and B, and 2 cohorts of participants with recurrent/refractory GBM grouped by O-6-methylguanine-DNA methyltransferase (MGMT) status - unmethylated or methylated - in Arm C.

Participants in Arms A and B are treated until completion of RT and participants in Arm C may continue treatment in the absence of safety concerns and disease progression.
