The purpose of this study is to characterize the mass balance, absorption, metabolism, and elimination pathways of orally administered [14C] rucaparib followed by cycle by cycle treatment with rucaparib continuing until disease progression or other reason for discontinuation

This is a Phase 1, open-label, non-randomized, mass balance study in patients with histologically or cytologically confirmed advanced solid tumors. Approximately 6 patients will be enrolled. The study will consist of 2 parts: a mass balance part (Part I) and a rucaparib treatment part (Part II).

Each patient will receive a single oral dose of 600 mg [14C] rucaparib (approximately 140 µCi) in the fasted state. Patients will be confined at the study site for the collection of blood samples and excreta for a maximum of 13 days, from Day -1. The patient can be discharged sooner than Day 13, if the discharge criteria are met. If the cumulative recovery of radioactivity exceeds 90% of the administered dose or if radioactivity in urine and feces is < 1% of the administered dose over a 24 hour period on two consecutive days, as determined by quick counts.

In Part II, the treatment with rucaparib in 28-day cycles will continue until progression of disease, unacceptable toxicity, or other reason for discontinuation.

Inclusion Criteria:

• Histologically or cytologically confirmed advanced solid tumor
• Part II only: Have a known deleterious BRCA1/2 mutation (germline or somatic) as determined by a local or central laboratory
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• Adequate bone marrow, renal, and liver function

Exclusion Criteria:

• Prior treatment with chemotherapy, radiation, antibody therapy or other immunotherapy, gene therapy, vaccine therapy, or angiogenesis inhibitors within 14 days prior to Day 1
• Participation in a trial involving administration of [14C]-labeled compound(s) within the last 6 months prior to Day 1
• Arterial or venous thrombi (including cerebrovascular accident), myocardial infarction, admission for unstable angina, cardiac angioplasty, or stenting within the last 3 months prior to Screening
• Pre-existing duodenal stent, recent or existing bowel obstruction, and/or any gastrointestinal disorder or defect that would, in the opinion of the Investigator, interfere with absorption of rucaparib
• Untreated or symptomatic central nervous system (CNS) metastases
• Evidence or history of bleeding disorder
• Participation in another investigational drug trial within 14 days prior to Day 1 (or 5 times the half-life of the drug, whichever is longer) or exposure to more than three new investigational agents within 12 months prior to Day 1
• Acute illness (eg, nausea, vomiting, fever, diarrhea) within 14 days prior to Day 1, unless mild in severity and approved by the Investigator and Sponsor's/designated medical representative
• Active second malignancy
