A Trial of Niraparib in BAP1 and Other DNA Double-Strand Break Repair Deficient Neoplasms (UF-STO-ETI-001)

Published: July 19, 2017

Primary Outcome Measures

    • Objective Response Rate [ Time Frame: 1 year ]
      Determine the objective response rate for patients with BAP1 and other DNA double- strand break repair pathway mutations

Secondary Outcome Measures

      • Progression Free Survival [ Time Frame: 1 year ]. Determine the median progression free survival
      • Progression Free Survival [ Time Frame: 3 months ]. Determine the progression free survival at 3 months
      • Progression Free Survival [ Time Frame: 6 months ].Determine the progression free survival at 6 months
      • Overall Survival [ Time Frame: 2 years ]. Estimate the median overall survival
      • Number of participants with treatment-related adverse events, as assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0 [ Time Frame: 1 year ]
        Determine the incidence, severity, and reversibility of the toxicities of niraparib using CTCAE v4.0

Other Outcome Measures

      • Number of DNA repair mechanism deficiencies [ Time Frame: 1 year ]. Explore the impact that specific DNA repair mechanism deficiencies have on tumor PARP inhibition.
      • Biomarker identification [ Time Frame: 1 year ]. Explore alternate biomarkers that predict response to PARP inhibition
