A Study of Rucaparib in Patients With Metastatic Castration-resistant Prostate Cancer and Homologous Recombination Gene Deficiency

Purpose

The purpose of this study is to determine how patients with metastatic castration-resistant prostate cancer, and evidence of a homologous recombination gene deficiency, respond to treatment with rucaparib.

Condition

  • Metastatic Castration Resistant Prostate Cancer

Eligibility

Eligible Ages
Over 18 Years
Eligible Genders
Male
Accepts Healthy Volunteers
No

Inclusion Criteria

  • Be 18 years old at the time the informed consent form is signed
  • Have a histologically or cytologically confirmed adenocarcinoma or poorly differentiated carcinoma of the prostate
  • Be surgically or medically castrated, with serum testosterone levels of ≤ 50 ng/dL (1.73 nM)
  • Experienced disease progression after having received at least 1 but no more than 2 prior next-generation androgen receptor-targeted therapies, and 1 prior taxane-based chemotherapy, for castration-resistant disease
  • Have a deleterious mutation in BRCA1/2 or ATM, or molecular evidence of other homologous recombination deficiency

Exclusion Criteria

  • Active second malignancy, with the exception of curatively treated non-melanoma skin cancer, carcinoma in situ, or superficial bladder cancer
  • Prior treatment with any PARP inhibitor, mitoxantrone, cyclophosphamide or any platinum-based chemotherapy
  • Symptomatic and/or untreated central nervous system metastases
  • Pre-existing duodenal stent and/or any gastrointestinal disorder or defect that would, in the opinion of the investigator, interfere with absorption of rucaparib
