NCT03824704

Brief Summary

This is an open label Phase 2, 2-stage, 2-cohort study to evaluate rucaparib in combination with nivolumab in patients with high-grade serous or endometroid ovarian cancer. Patients entering the following cohorts must have BRCA mutational status confirmed by a central lab:

  • Cohort A1: No BRCA mutation in tumor; high level of LOH (loss of heterozygosity)
  • Cohort A2: BRCA mutation in tumor

Outcome Measures

Primary Outcomes (2)

  • Objective Response Rate (ORR) by RECIST v1.1 as Assessed by the Investigator

    Objective response rate (ORR) is defined as the percentage of patients with a best confirmed response of complete response (CR) or partial response (PR) by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as assessed by the investigator.

    From enrollment until disease progression (up to approximately 2 years)

  • The Effect of Rucaparib on the Immune Microenvironment

    Change in expression of the immune marker PD-L1 pre and post-rucaparib treatment; Cohort A2 only

    From enrollment to primary completion of study (up to approximately 2 years)

Secondary Outcomes (3)

  • ORR by RECIST v1.1 and Gynecological Cancer InterGroup (GCIG) Cancer Antigen 125 (CA-125 Criteria)

    For patients with measurable disease, every 8 weeks after the start of combination treatment for 3 years, then every 24 weeks thereafter until disease progression or up to 25 months. Study data collection expected to last for 2 years.

  • Progression-free Survival (PFS)

    From randomization until disease progression (up to approximately 2 years)

  • Duration of Response (DOR)

    For patients with measurable disease, every 12 weeks after the start of combination treatment for 3 years, then every 24 weeks thereafter until disease progression. Study data collection expected to last for 2 years

Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥ 18 years of age
  • Adequate organ function
  • Life expectancy ≥ 16 weeks
  • Women of childbearing potential must have a negative serum pregnancy test
  • High-grade serous or endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer
  • Received 1 or 2 prior regimens, including ≥ 1 prior platinum-based therapy and have platinum-sensitive disease
  • Relapsed/progressive disease (confirmed by radiologic assessment)
  • Willing and able to have a biopsy of tumor at screening and after 4 weeks of treatment.
  • Measurable disease (RECIST v1.1)- Cohort A1 only
  • ECOG performance status of 0 to 1

You may not qualify if:

  • Evidence of interstitial lung disease, active pneumonitis, myocarditis, or history of myocarditis.
  • Active, known or suspected autoimmune disease (eg, autoimmune hepatitis).
  • Condition requiring systemic treatment with either corticosteroids
  • Prior treatment with a PARP inhibitor or immune checkpoint inhibitor.
  • Non-epithelial tumors (pure sarcomas) or ovarian tumors with low malignant potential (ie, borderline tumors) or mucinous tumors. Mixed Mullerian tumors/carcinosarcomas are allowed.
