A Phase 1B/2 Multicohort Umbrella Study to Evaluate the Safety and Efficacy of Novel Treatments And/Or Combinations of Treatments in Participants With Ovarian Cancer (OPAL)
In Brief
A Phase 2 clinical trial evaluating Niraparib, TSR-042, and 3 other interventions for Ovarian Neoplasms. Completed, enrolled 77 participants across 28 sites in 3 countries.
Detailed Summary
This study will evaluate the efficacy and safety of niraparib and novel treatment combinations of niraparib as described within each cohort-specific supplement in participants with ovarian, fallopian tube, or primary peritoneal cancer. Cohort A (single arm) includes participants with recurrent ovarian cancer. Cohort B will not be initiated. Cohort C (randomized-2 arms) includes participants with newly diagnosed ovarian cancer.

Timeline
Interventions
Niraparib is a potent, orally active PARP1 and PARP2 inhibitor being developed as a treatment for participants with tumors that harbor defects in the homologous recombination deoxyribonucleic acid (DNA) repair pathway or that are driven by PARP-mediated transcription factors.
TSR-042 is a humanized monoclonal antibody that binds with high affinity to Programmed cell death protein 1 (PD-1) resulting in inhibition of binding to programmed death receptor ligands 1 and 2 (PD-L1 and PD-L2).
Bevacizumab is an Food Drug and Administration (FDA) approved antiangiogenic recombinant humanized monoclonal Immunoglobulin (Ig) G1 antibody against the vascular endothelial growth factor protein, which has been shown to be efficacious against a variety of different cancer types, including colon cancer, lung cancer, glioblastoma, and renal-cell carcinoma.
Carboplatin will be infused intravenously over 60 minutes at the prescribed dose of area under the concentration versus time curve of 5 to 6 mg/milliliters (mL) per minute on Day 1 of every 21-day cycle
Paclitaxel will be administered intravenously over 180 minutes at the prescribed dose of 175 mg/meter square (m\^2) on Day 1 of every 21-day cycle
