Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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).


Secondary Outcome Measures :
  1. 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)

  2. 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.

  3. 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.

  4. Progression-Free Survival [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]
    Measure of clinical benefit, defined as the duration from study enrollment to objective tumor progression.

  5. Overall Survival [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]
    Measure of clinical benefit, defined as the duration from study enrollment to death.

  6. Safety and Tolerability of rucaparib [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]
    Incidence of AEs, clinical lab abnormalities, and dose modifications.

  7. Steady state minimum concentration [Cmin] [ Time Frame: From first dose of study drug until disease progression (up to approximately 2 years) ]
    Rucaparib PK

Criteria

Key Inclusion Criteria:

  • 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
