Primary Purpose: Treatment
Official Title: A Phase 2 Open-Label, Single-Arm Study to Evaluate the Efficacy and Safety of the Combination of Niraparib and Dostarlimab (TSR-042) in Patients With Platinum-Resistant Ovarian Cancer (MOONSTONE)
Actual Study Start Date : October 3, 2019
Estimated Primary Completion Date : September 15, 2021
Estimated Study Completion Date : February 28, 2024


Arm Intervention/treatment
Experimental: Niraparib+TSR-042
Participants will receive both Niraparib and TSR-042 to evaluate the efficacy and safety of the combination of both drugs. Niraparib will be administered once daily (QD) continuously until Progressive disease (PD) or toxicity. Dostarlimab (TSR-042) will be administered via a 30-minute intravenous (IV) infusion on Day 1 every 3 weeks (Q3W) during Cycles 1 through 4. Beginning at Cycle 5, dostarlimab (TSR-042) will be administered via a 30-minute IV infusion on Day 1 of each 6-week cycle until PD or toxicity, for a maximum of 3 years.
Drug: Niraparib
Niraparib is a potent, orally active poly (adenosine diphosphate-ribose) polymerase (PARP)-1 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.
Other Name: ZEJULA

Drug: TSR-042
TSR-042 is a humanized monoclonal antibody that binds with high affinity to programmed cell death-1 (PD-1) resulting in inhibition of binding to programmed cell-death receptor ligands 1 and 2 (PD-L1 and PD-L2).
Other Name: Dostarlimab




Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: Up to 5 years ]
    ORR is defined as the proportion of participants who have achieved confirmed complete response (CR) or partial response (PR), evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 based on Investigator assessment.


Secondary Outcome Measures :
  1. Duration of Response (DOR) [ Time Frame: Up to 5 years ]
    DOR is defined as the time from first documentation of response (CR or PR) until the time of first documentation of disease progression by RECIST v.1.1 based on Investigator assessment or death by any cause in the absence of progression by RECIST v.1.1.

  2. Progression-free Survival (PFS) [ Time Frame: Up to 5 years ]
    PFS is defined as the time from the date of the first dose of study treatment to the earlier date of assessment of progression by RECIST v.1.1 based on Investigator assessment or death by any cause in the absence of progression by RECIST v.1.1.

  3. Overall Survival (OS) [ Time Frame: Up to 5 years ]
    OS is defined as the time from the date of the first dose of study treatment to the date of death by any cause.

  4. Disease Control Rate (DCR) [ Time Frame: Up to 5 years ]
    DCR is defined as the percentage of patients who have achieved best overall response (BOR) of CR, PR, or stable disease (SD) per RECIST v.1.1 based on the Investigator's assessment.

  5. ORR Based on Independent Review Committee Assessment [ Time Frame: Up to 5 years ]
    ORR based on independent review committee assessment is defined as the percentage of participants who have achieved confirmed CR or PR per RECIST v1.1 based on the independent review committee assessment.

  6. DOR based on Independent Review Committee Assessment [ Time Frame: Up to 5 years ]
    DOR is defined as the time from first documentation of response (CR or PR) until the time of first documentation of disease progression by RECIST v.1.1 based on Independent Review Committee Assessment or death by any cause in the absence of progression by RECIST v.1.1.

  7. PFS based on Independent Review Committee Assessment [ Time Frame: Up to 5 years ]
    PFS is defined as the time from the date of the first dose of study treatment to the earlier date of assessment of progression by RECIST v.1.1 based on Independent Review Committee Assessment or death by any cause in the absence of progression by RECIST v.1.1.

  8. DCR based on Independent Review Committee Assessment [ Time Frame: Up to 5 years ]
    DCR is defined as the percentage of participants who have achieved BOR of CR, PR, or SD per RECIST v.1.1 based on Independent Review Committee Assessment.
