This is a Phase 1 open-label, dose-escalation, safety and pharmacokinetic study of rucaparib administered twice daily (BID) to Japanese patients with a solid tumor who have failed previous standard treatment for their cancer. A recommended dose of rucaparib for Japanese patients will be determined in a dose-escalation portion and then further evaluated in a dose-expansion portion of the study.

  • For patients enrolled in the dose-expansion portion, has high-grade serous ovarian cancer, or BRCA 1/2 mutated breast cancer, or other solid tumor with BRCA 1/2 or related gene mutation

• Have to have evaluable disease (i.e. disease can be followed on scans.)

• Be willing and able to fast for at least 14 hours

Exclusion Criteria:
