Niraparib in Metastatic Pancreatic Cancer After Previous Chemotherapy (NIRA-PANC): a Phase 2 Trial

Niraparib in Metastatic Pancreatic Cancer After Previous Chemotherapy (NIRA-PANC): a Phase 2 Trial

The goal of this clinical research study is to learn if Niraparib can help to control metastatic pancreatic cancer. The safety of this drug will also be studied. Niraparib is FDA approved and commercially available for the treatment of ovarian cancer. Its use in this study is investigational.

• Able to swallow oral study drug
• Histologically or cytologically confirmed adenocarcinoma of the exocrine pancreas
• Measurable disease
• Patients with history of other, non-pancreatic cancers with no evidence of active disease are eligible.
• Participants who have had any prior chemotherapy as first line and/or second line therapy for metastatic disease are eligible to seek enrollment. Patients who refuse chemotherapy or do not tolerate chemotherapy are eligible.

• Women must have a negative serum pregnancy test within 72 hours to taking study treatment.
• Women of child-bearing potential and men with partners of child-bearing potential must agree to practice sexual abstinence, or to use approved forms of contraception prior to study entry, for the duration of study participation, and for 180 days following completion of therapy.

• Patient has had prior treatment with a known poly polymerase inhibitor
• Psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant, breast feeding or expecting to conceive children while receiving study treatment and for 180 days after the last dose of study treatment. There is a potential for congenital abnormalities and for this regimen to harm breast feeding infants.

• Patients must not have received a transfusion (platelets or red blood cells) within 4 weeks of the first dose of study treatment
• Patients must not have current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study or interfere with the patient's participation for the full duration of the study treatment or that makes it not in the best interest of the patient to participate
• Patients must not have known, symptomatic brain or leptomeningeal metastases
• Patient must not have any known history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)
