A Trial of Niraparib in BAP1 and Other DNA Damage Response (DDR) Deficient Neoplasms (UF-STO-ETI-001)

Trial Status: Active

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.

Inclusion Criteria

  • Age ≥18 years
  • Histologically confirmed clinical diagnosis of incurable cancer
  • Confirmed diagnosis of uveal melanoma, mesothelioma, renal cell carcinoma (clear cell subtype), or cholangiocarcinoma (Cohort A only)
  • Known DNA damage repair mutation including any one of the following: ARID1A, ATM, ATR, BACH1 (BRIP1), BAP1, BARD1, BLM, CHEK1, CHEK2, CDK2, CDK4, ERCC, FAM175A, FEN1, IDH1, IDH2, MRE11A, NBN (NBS1), PALB2, POLD1, PRKDC (DNA-PK) PTEN, RAD50, RAD51, RAD52, RAD54, RPA1, SLX4, WRN, or XRCC. Only CLIA certified next generation sequencing (NGS) assays are acceptable. Variants of unknown significance (VUS) will be allowed to enroll on study. (Cohort B only)
  • Prior treatment with standard systemic therapy (must have exhausted or declined all known and currently approved effective life prolonging therapies)
  • Must have formalin-fixed paraffin embedded (FFPE) tissue available for research purposes. Tissue must have been obtained within the last 3 years from a core or excisional biopsy.
  • Measurable disease by RECIST (v 1.1) criteria
  • Adequate organ function
  • ECOG Performance Status of 0-1
  • Life expectancy ≥ 12 weeks
  • Women of childbearing potential must have a negative serum or urine pregnancy test within 7 days prior to the first dose AND be using an adequate method of contraception to avoid pregnancy throughout the study and for at least 180 days after the last dose of study drug to minimize the risk of pregnancy.
  • Males with female partners of child-bearing potential must agree to use physician-approved contraceptive methods (e.g., abstinence, condoms, vasectomy) throughout the study and should avoid conceiving children for 180 days following the last dose of study drug. In addition, men must not donate sperm during niraparib therapy and for 180 days after receiving the last dose of niraparib.
  • Subjects must agree to not donate blood during the study or for 90 days after the last dose of study treatment.
  • Subjects receiving oral corticosteroids may continue as long as their dose is stable for least 4 weeks prior to initiating protocol therapy.
  • If a new biopsy is needed for diagnostic reasons, the biopsy must be performed from a tumor site that is not the only site of measurable disease.

Exclusion Criteria

  • Prior exposure to PARP inhibitors
  • Subject has received or is planning to receive live vaccines within 30 days prior to the first dose of oral treatment and while participating in the trial
  • Known BRCA1 or BRCA2 mutation
  • Pathologic diagnosis of prostate cancer as the cancer to be treated in cohort B
  • Simultaneous enrollment in any other interventional clinical trial
  • Major surgery ≤ 3 weeks of study enrollment (Subject must have recovered from any effects of any major sugery.)
  • Investigational therapy ≤ 4 weeks of first day of dosing of study drug
  • Radiotherapy to > 20% of the bone marrow within 4 weeks of the first dose of study drug
  • Known hypersensitivity to the components of niraparib or the excipients
  • Platelet or red blood cell transfusion ≤ 4 weeks of first dose of study drug
  • Colony-stimulating factors within 4 weeks prior to starting protocol therapy
  • More than one active malignancy at the time of enrollment (Subjects with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen [as determined by the treatment physician and approved by the PI] may be included).
  • Known, active symptomatic brain or leptomeningeal metastases
  • Subject has had any known Grade 3 or 4 anemia, neutropenia or thrombocytopenia due to prior chemotherapy that persisted > 4 weeks and was related to the most recent treatment.
  • Known history of myelodysplastic syndrome or acute myeloid leukemia
  • Females or males of childbearing potential who are unwilling or unable to use an acceptable method of birth control to avoid pregnancy for the entire study period and for at least 180 days after the last dose of study drug.
  • Females who are pregnant or breastfeeding
  • History of any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of protocol therapy or that might affect the interpretation of the results of the study or that puts the subject at high risk for treatment complications, in the opinion of the treating physician or study PI.
  • Prisoners or subjects who are involuntarily incarcerated.
  • Subjects who are compulsorily detained for treatment of either a psychiatric or physical illness.
  • Subjects demonstrating an inability to comply with the study and/or follow-up procedures

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.
