About
This phase IB trial evaluates the effect of niraparib and TSR-042 in treating patients with BRCA-mutated breast, pancreas, ovary, fallopian tube, or primary peritoneal cancer that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as TSR-042, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving niraparib and TSR-042 may kill more cancer cells.
Full description
OUTLINE:
Patients receive niraparib orally (PO) once daily (QD) on days 1-28 of cycle 1. Beginning cycle 2, patients receive niraparib PO QD on days 1-21 and dostarlimab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity. Beginning cycle 6, patients receive niraparib PO QD on days 1-42 and dostarlimab IV over 30 minutes on day 1. Cycles repeat every 42 days for up to 24 months in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo biopsy, blood sample collection, and computed tomography (CT) or magnetic resonance imaging (MRI) throughout the study.
After completion of study treatment, patients are followed up for 30 days, every 6 months for 2 years, and then annually for up to 5 years.

-
International normalized ratio (INR) or prothrombin time (PT) =< 1.5 x ULN unless patient is receiving anticoagulant therapy as long as PT or partial thromboplastin (PTT) is within therapeutic range of intended use of anticoagulants. Activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
-
Asymptomatic patients with stable brain metastases must have no evidence of bleeding and no need for steroids or anti-epileptic medications for at least 7 days prior to day 1

Female participant has a negative urine or serum pregnancy test within 7 days prior to taking study treatment if of childbearing potential and agrees to abstain from activities that could result in pregnancy from screening through 180 days after the last dose of study treatment or is of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):

Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. Information must be captured appropriately within the site's source documents. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient
