Brief Summary:
This open-label, non-randomized study will investigate the use of niraparib in patients with tumors known to have mutations in BAP1 and other select DNA damage response pathway genes.

Condition or disease Intervention/treatment Phase
Mesothelioma Uveal Melanoma Renal Cell Carcinoma Cholangiocarcinoma Drug: Niraparib Phase 2

Detailed Description:
BAP1 is an ubiquitin ligase that is critical in helping to regulate the cell cycle, cellular differentiation, and cell death. This protein is also intimately involved with DNA double-strand break repair. Germline mutations in the BAP1 gene are associated with a hereditary cancer syndrome that increases the risk of uveal melanoma, mesothelioma and renal cell carcinoma. PARP is another protein that is crucial in DNA repair and enables continued cell replication and survival. It is hypothesized that PARP inhibition with niraparib will result in significant cytoreduction in patient tumors with mutations in BAP1 and other components of the DNA damage response pathway through synthetic lethality. Synthetic lethality is the inhibition of a gene that a cell relies on to compensate for the loss of another gene, resulting in the cell's demise.

  3. Progression Free Survival [ Time Frame: 6 months ]
    Determine the progression free survival at 6 months in each cohort and histologic subset of subjects

  4. Overall Survival [ Time Frame: 2 years ]
    Estimate the median overall survival

  5. 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:
  1. Number of DNA repair mechanism deficiencies [ Time Frame: 1 year ]
    Explore the impact that specific DNA repair mechanism deficiencies have on tumor PARP inhibition

  2. Biomarker identification [ Time Frame: 1 year ]
    Explore alternate biomarkers that predict response to PARP inhibition
