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

Inclusion Criteria:

• Confirmed diagnosis of high-grade serous or endometrioid epithelial ovarian, primaryperitoneal, or fallopian tube cancer.
• Received ≥2 prior platinum-based treatment regimens including platinum based regimenthat must have been administered immediately prior to maintenance therapy in thistrial.
• Received no more than 1 non-platinum chemotherapy regimen. Prior hormonal therapy willnot be counted as a non-platinum regimen.
• Must have had at least a 6-month disease-free period following prior treatment withthe penultimate platinum-based chemotherapy and achieved a response.
• For the last chemotherapy course prior to study entry, patients must have received aplatinum-based doublet chemotherapy regimen and have achieved a CR or PR (as definedby 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 ofrecurrence), and synchronous endometrial cancer (Stage 1A) with ovarian cancer.
• Prior treatment with any PARP inhibitor, including rucaparib. Patients who receivedprior 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-basedregimen and/or during the period between the last dose of chemotherapy of that regimenand randomization to maintenance treatment in this study.
