        Inclusion Criteria:

          -  Confirmed diagnosis of high-grade serous or endometrioid epithelial ovarian, primary
             peritoneal, or fallopian tube cancer.

          -  Received ≥2 prior platinum-based treatment regimens including platinum based regimen
             that must have been administered immediately prior to maintenance therapy in this
             trial.

          -  Received no more than 1 non-platinum chemotherapy regimen. Prior hormonal therapy will
             not be counted as a non-platinum regimen.

          -  Must have had at least a 6-month disease-free period following prior treatment with
             the penultimate platinum-based chemotherapy and achieved a response.

          -  For the last chemotherapy course prior to study entry, patients must have received a
             platinum-based doublet chemotherapy regimen and have achieved a CR or PR (as defined
             by RECIST) and/or a GCIG CA-125 response.

          -  Have sufficient archival tumor tissue for analysis.

        Exclusion Criteria:

          -  History of prior cancer except for non-melanoma skin cancer, breast cancer curatively
             > 3 years ago, curatively treated solid tumor (>5 years ago without evidence of
             recurrence), and synchronous endometrial cancer (Stage 1A) with ovarian cancer.

          -  Prior treatment with any PARP inhibitor, including rucaparib. Patients who received
             prior iniparib are eligible.

          -  Untreated or symptomatic central nervous system metastases.

          -  Pre-existing duodenal stent and/or any gastrointestinal disorder or defect that would,
             in the opinion of the Investigator, interfere with absorption of study drug.

          -  Required drainage of ascites during the final 2 cycles of their last platinum-based
             regimen and/or during the period between the last dose of chemotherapy of that regimen
             and randomization to maintenance treatment in this study.
