Primary Outcome Measures:
  • Progression-free survival per RECIST version 1.1 [ Time Frame: Screening; at the end of every 8 weeks (±4 days) of treatment; at disease progression; study data collection expected to last for ~2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Best overall response rate achieved (from baseline to disease progression) per RECIST version 1.1 and GCIG CA-125 response criteria. [ Time Frame: Screening; at the end of every 8 weeks (±4 days) of treatment; at disease progression; study data collection expected to last for ~2 years (RECIST v1.1). ] [ Designated as safety issue: No ]
    Screening, Day 1 of every cycle, at the end of every 8 weeks (±4 days) of treatment, as clinically indicated, and at disease progression (GCIG CA-125 response criteria).

  • Duration of response per RECIST version 1.1 [ Time Frame: Screening; at the end of every 8 weeks (±4 days) of treatment; at disease progression; study data collection expected to last for ~2 years ] [ Designated as safety issue: No ]
  • Incidence of adverse events, clinical laboratory abnormalities, and dose modifications [ Time Frame: Every day starting with signing of consent until 28 days after discontinuation of treatment; study data collection expected to last for ~2 years ] [ Designated as safety issue: Yes ]
  • Trough (Cmin) level of rucaparib concentrations [ Time Frame: 2 weeks, 1 month, 2 months and 3 months after 1st dose ] [ Designated as safety issue: No ]

Estimated Enrollment: 180
Study Start Date: September 2013
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ovarian cancer
All patients with platinum-sensitive, relapsed, high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer will take oral rucaparib
Drug: Oral rucaparib
All patients will ingest rucaparib twice a day continuously until disease progression. Patients may take rucaparib on an empty stomach or with food. Each dose should be taken with at least 8 oz (240 mL) of room temperature water. Tablets should be swallowed whole. Each patient will take the Recommended Phase 2 Dose established in the CO-338-010 study.

Detailed Description:

Rucaparib is an orally available, small molecule inhibitor of poly-adenosine diphosphate [ADP] ribose polymerase (PARP) being developed for treatment of ovarian cancer associated with homologous recombination (HR) DNA repair deficiency (HRD). The safety and efficacy of rucaparib has been evaluated in several Phase 1 and Phase 2 studies. An oral formulation is the focus of current development efforts. Rucaparib is currently being investigated as monotherapy in patients with cancer associated with breast cancer susceptibility gene 1 (BRCA1) or BRCA2 mutations.

Clinical data with PARP inhibitors indicate there is an ovarian cancer patient population beyond just those with germline BRCA (gBRCA) mutations that may benefit from treatment with a PARP inhibitor. This study will define a molecular signature of HRD in ovarian cancer that correlates with response to rucaparib and enables selection of appropriate ovarian cancer patients for treatment with rucaparib. The HRD signature will be based on an association between the extent of genomic scarring (a downstream consequence of HRD) in a patient's tumor and observed clinical benefit from rucaparib treatment. Genomic scarring can be assessed by quantifying the extent of loss of heterozygosity across the tumor genome (tumor genomic LOH). One of the main advantages of detecting tumor genomic LOH is that it can identify HRD tumors regardless of the underlying mechanisms, which include both known (i.e., BRCA mutations) and unknown genetic and other mechanisms.

Once determined, this signature will be prospectively applied in the final analysis of the planned Phase 3 pivotal study (ARIEL3). This Phase 2 study (ARIEL2) will also compare archival versus recently collected tumor tissue in order to validate the use of archival tumor tissue for assessment of HRD status in ARIEL3.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed diagnosis of high-grade epithelial ovarian (serous or endometrioid histology), fallopian tube, or primary peritoneal cancer
  • Relapsed/progressive disease as confirmed by CT scan
  • Received ≥1 prior platinum-based treatment regimen
  • Received platinum-based regimen as last treatment; continuous or switch maintenance treatment as part of this regimen is permitted
  • Sensitive to last platinum regimen (disease progression >6 months after the last dose of platinum)
  • If <55 years of age at diagnosis, prior history of breast cancer, or close relative (first or second degree) with ovarian cancer or early onset (<age 50) breast cancer, must have been previously tested for gBRCA mutation; after 15 patients harboring the gBRCA mutation are enrolled, no additional patients with a known gBRCA mutation will be allowed to enroll.
  • Have biopsiable and measurable disease

Exclusion Criteria:

  • History of prior cancers except for those that have been curatively treated, with no evidence of cancer currently (provided all chemotherapy was completed >6 months prior and/or bone marrow transplant >2 years prior to first dose of rucaparib).
  • Prior treatment with any PARP inhibitor
  • Symptomatic and/or untreated central nervous system metastases
  • Pre-existing duodenal stent and/or any other gastrointestinal disorder or defect that would, in the opinion of the Investigator, interfere with absorption of rucaparib
