Phase 1

Registration Number
NCT02986100
Lead Sponsor

Brief Summary

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

Detailed Description

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

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
