The only way to improve cancer detection, prevention, and treatment is through research. People participating in research contribute to medical knowledge and have opportunity to receive cutting-edge care.

Treating Early-Stage HER2-Negative Breast Cancer with a PARP Inhibitor (Niraparib) and Immunotherapy (Dostarlimab) in People with a BRCA or PALB2 Mutation
About the Study
This study will look at how well the drugs (a ) and Dostarlimab (an ) treat breast cancer in people with an inherited , or mutation.
What the Study Entails
The study will have three different groups of participants (Group A, Group B and Group C). Participants in each group will receive both study drugs. The timing of the drugs differs by group. The study is open label, which means that all participants will know which group they are assigned to.
This study is open to participants with and participants with ER-positive breast cancer. Participants with triple negative breast cancer will be (randomly assigned) to one of two treatment arms (Group A or Group B).
- Group A: Participants will receive together with Dostarlimab for 18 weeks
- Group B: Participants will receive alone for 3 weeks, followed by with Dostarlimab for 15 weeks
All participants with ER-positive breast cancer will be placed into Group C.
- Group C: Participants will receive with Dostarlimab for 18 weeks
Participants will receive treatment for 18 weeks. After 18 weeks, participants will be evaluated to determine if they are a candidate for surgery or if they will require additional treatment.
