eligibility Criteria
The following eligibility criteria pertain to patients enrolling into PART 2 of the study: Inclusion: * Have a histologically confirmed diagnosis of high grade serous or Grade 2 or Grade 3 endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer * Received at least 3 prior chemotherapy regimens. Non-chemotherapy regimens and maintenance therapies administered as single agent treatment will not count as a chemotherapy regimen * Relapsed/progressive disease as confirmed by CT scan * Have biopsiable and measurable disease. Note: biopsy is optional for patients known to harbor a deleterious gBRCA mutation * Have sufficient archival formalin-fixed paraffin-embedded (FFPE) tumor tissue available for planned analyses Exclusion: * 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 * Hospitalization for bowel obstruction within 3 months prior to enrollment

primary Outcomes
  1. description
    The primary efficacy endpoint of PFS is calculated as 1+ the number of days from the first dose of study drug to disease progression by RECIST (Response Evaluation Criteria in Solid Tumors), as determined by the investigator or death due to any cause, whichever occurs first. Progression is defined using RECIST v1.1, as at least a 20% increase in the sum of the longest diameter of target lesions, or a measureable increase in a non-target lesion, or the appearance of new lesions.
    measure
    Progression-free Survival (PFS) According to RECIST v1.1 in Molecularly-defined HRD (Homologous Recombination Deficiency) Subgroups (Part 1 of Study)
    time Frame
    Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.
  2. description
    The confirmed response rate by RECIST v1.1 is defined as the percentage of patients with a confirmed complete response (CR) or partial response (PR) on subsequent tumor assessment at least 28 days after first response documentation. Complete response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.
    measure
    Objective Response Rate (ORR) by RECIST v1.1 in Molecularly-defined HRD Subgroups (Part 2 of Study)
    time Frame
    Assessments every 8 weeks from C1D1 until disease progression, death or withdrawal of consent. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3 years.

    The endpoint of ORR defined as the percentage of patients with a best response of CR or PR using RECIST v 1.1 or a response per Gynecologic Cancer InterGroup cancer antigen 125 (GCIG CA-125) criteria. Complete response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter. A response to CA-125 has occurred if there is at least a 50% decrease from baseline: 1. in a sample collected after initiation of study treatment AND 2. that is confirmed in a subsequent sample collected ≥21 days after the prior sample. The absolute value of this confirmatory sample must be ≤110% of the prior sample. The date when the first sample with a 50% decrease from baseline is observed is the date of the CA-125 response.

    Duration of response (DOR) for any confirmed RECIST CR or PR measured from the date of the first occurrence of a response until the first occurrence of progressive disease (PD) per RECIST.

Full study description
brief Summary
The purpose of this study is to determine which patients with ovarian, fallopian tube, and primary peritoneal cancer will best respond to treatment with rucaparib.
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 to ARIEL2 PART 2 and 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. This study will include 2 parts: PART 1 (completed enrollment): Evaluation of HRD status and rucaparib efficacy in patients who received ≥1 prior platinum-based regimen and had platinum-sensitive disease PART 2 (completed enrollment): Evaluation of HRD status and rucaparib efficacy in patients who received at least 3 prior chemotherapy regimens
