Experimental: Rucaparib
Eligible patients will be enrolled in either Cohort A or Cohort B. Cohort A: Up to 200 patients with deleterious mutations in BRCA1, BRCA2, PALB2, RAD51C or RAD51D. Cohort B (Exploratory): Up to 20 patients with deleterious mutations in BARD1, BRIP1, FANCA, NBN, RAD51 or RAD51B. |
Drug: Rucaparib
Oral rucaparib will be administered twice daily. The starting dose will be 600 mg daily (BID).

- Best Overall Response Rate by Investigator [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]Best overall response rate as assessed by the investigator by RECIST v1.1 (or by RECIST v1.1 and PCWG3 in patients with advanced prostate cancer).
- Overall Response Rate by Independent Radiology Review [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]Best overall response rate by independent radiology review by RECIST v1.1 (or by RECIST v1.1 and PCWG3 in patients with advanced prostate cancer)
- Duration of Response [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]Measure of clinical benefit, defined as the time from initial tumor response to documented tumor progression.
- Disease Control Rate [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]Measure of clinical benefit, defined as the percentage of complete response (CR), partial response (PR), and stable disease (SD) beyond 16 weeks.

Note: Breast cancer patients that are HER2 negative and have germline BRCA1 or BRCA2 mutations AND patients with epithelial ovarian cancer, fallopian tube cancer, primary peritoneal cancer or metastatic castration-resistant prostate cancer with BRCA1 or BRCA2 mutations are ineligible for this trial.
- At least one prior line of therapy extending overall survival or standard of care therapy for advanced disease. Note: Some tumor types have specific inclusion/exclusion criteria for previous treatments.
- ECOG 0 or 1
- Tumor tissue available for genomic analysis, or must be willing to have a biopsy if no archival tumor tissue available
- Adequate organ function
- Life expectancy of 4 months
Key Exclusion Criteria:
- Active central nervous system brain metastases, leptomeningeal disease or primary tumor of CNS origin
- Active second malignancy (Exceptions: Successfully treated malignancy with no active disease for 1 year, surgically cured and/or low-risk tumors, or patients receiving ongoing anticancer hormonal therapy for a previously treated cancer)
- Pre-existing gastrointestinal disorders/conditions interfering with ingestion/absorption of rucaparib
- Prior treatment with a PARP inhibitor
- More than 3 prior lines of chemotherapy in the locally advanced/metastatic setting
- History of myelodysplastic syndrome or acute myeloid leukemia
