Trial Title: Phase 3 Study of Rucaparib as Switch Maintenance After Platinum in Relapsed High Grade Serous or Endometrioid Ovarian Cancer (ARIEL3)

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
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.

Study Arms:
- Rucaparib (Type: EXPERIMENTAL): Oral tablets administered twice daily with 8 oz (240 mL) of water on an empty stomach or with food; 28-day cycles of treatment. Doses should be taken as close to 12 hours apart as possible, preferably at the same times every day. Tablets should be swallowed whole.
- Placebo (Type: PLACEBO_COMPARATOR): Oral tablets administered twice daily with 8 oz (240 mL) of water on an empty stomach or with food; 28-day cycles of treatment. Doses should be taken as close to 12 hours apart as possible, preferably at the same times every day. Tablets should be swallowed whole.
