A Study of Rucaparib as Switch Maintenance Following Platinum-Based Chemotherapy in Patients With Platinum-Sensitive, High-Grade Serous or Endometrioid Epithelial Ovarian, Primary Peritoneal or Fallopian Tube Cancer
Patients enrolled into this study will be stratified into 3 groups based on gene mutations identified in their tumor tissue. The purpose of this study is to evaluate patient response to maintenance treatment with rucaparib versus placebo. Response to treatment will be analyzed based on homologous recombination (HR) status of tumor samples.
- 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.
- 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.

Trial Objectives and Outline
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). Clinical data have shown that ovarian cancer patients with and without evidence of a gBRCA mutation benefit from treatment with a PARP and that maintenance treatment with a PARP inhibitor following a response to platinum-based treatment increases PFS in patients with ovarian cancer. While patients with a BRCA mutation derived the most benefit, patients without evidence of a BRCA mutation also derived significant benefit. Patients enrolled into this study will be stratified into 3 groups based on tumor HRD status. The purpose of this study is to identify which of these groups of patients will most likely benefit from treatment with rucaparib. It is anticipated that rucaparib will provide therapeutic benefit and increase PFS in patients with HRD associated with a BRCA gene mutation or other HR gene alteration.
