Niraparib and Dostarlimab as Neoadjuvant Treatment for Patients with BRCA-Mutated or PALB2-Mutated Stage I-III Breast Cancer
This phase II trial studies the effects of niraparib in combination with dostarlimab prior to surgery in treating BRCA-mutated or PALB2-mutated stage I-III breast cancer. Niraparib is a PARP inhibitor, which means that it blocks an enzyme (proteins that help chemical reactions in the body occur) in cells called PARP. PARP 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. Dostarlimab stimulates the immune system by blocking the PD-1 pathway. The PD-1 pathway controls the bodys natural immune response, but for some types of cancer, the immune system does not work as it should and is prevented from attacking tumors. Dostarlimab works by blocking the PD-1 pathway, which may help your immune system identify and catch tumor cells. Giving niraparib in combination with dostarlimab may work better against the tumor and maximize tumor shrinkage before surgery.
