Study Director

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.

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.

A DLT is defined as one of the following toxicities occurring during the DLT assessment window:

Grade ≥3 non-hematologic, non-hepatic major organ adverse event (AE) Grade 4 neutropenia lasting \>7 days Grade ≥3 febrile neutropenia Grade 3 thrombocytopenia with clinically significant bleeding Grade 4 thrombocytopenia lasting \> 3 days and requiring transfusion, or any decreased platelet count \<15,000/mm3/ \<15.0 x 109/L Grade ≥4 anemia Grade ≥3 total bilirubin or hepatic transaminases (ALT or AST)

A treatment-emergent adverse event (TEAE) is defined as an AE that had an onset date on or after first dose of study treatment or was worsening in severity from baseline (pretreatment) up to 30 days following permanent study treatment discontinuation or initiation of new anti-cancer therapy, whichever occurs first.

An SAE is any untoward medical occurrence that, at any dose meets at least one of the following criteria: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is considered a significant medical AE based on medical judgment.

Modified DCR is defined as the percentage of participants with complete response (CR), partial response (PR) or stable disease (SD) per RANO criteria as the response assessment at the end-of-treatment (EOT) visit.

ORR (objective response rate) is defined as percentage of participants with best overall response of CR or PR per RANO criteria (confirmed by a subsequent tumor assessment at least four weeks apart).

Data shows the number of participants who received treatment for the given number of cycles.

The average dose intensity per participant = total dose (mg) per participant / duration of treatment (days).

DCR is defined as the percentage of participants with best overall response of CR, PR or SD per RANO criteria. CR or PR will be confirmed by a subsequent tumor assessment at least four weeks apart

ORR is defined as percentage of participants with best overall response of CR or PR per RANO criteria (confirmed by a subsequent tumor assessment at least four weeks apart).

Clinical benefit rate (CBR) is defined as the percentage of participants with best overall response of CR, PR or SD ≥ 24 weeks per RANO criteria (confirmed by a subsequent tumor assessment at least four weeks apart).

DOR is defined as the time from the date of the earliest documented response to disease progression or death for any cause whichever occurs earlier (confirmed by a subsequent tumor assessment at least four weeks apart).

PFS is defined as the time from the first dose date to disease progression per RANO criteria or death, whichever occurs first.

OS is defined as the time from the first dose date to date of death for any cause.

A treatment-emergent adverse event (TEAE) is defined as an AE that had an onset date on or after first dose of study treatment or was worsening in severity from baseline (pretreatment) up to 30 days following permanent study treatment discontinuation or initiation of new anti-cancer therapy, whichever occurs first. An SAE is any untoward medical occurrence that, at any dose meets at least one of the following criteria: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, is considered a significant medical AE based on medical judgment.
