Summary

This trial is testing Niraparib as a possible treatment for triple negative breast cancer.

Who is the study for?
This trial is for adults with non-metastatic triple negative breast cancer who've had surgery and are planning postoperative radiation therapy. They must have some remaining invasive disease, not be pregnant or breastfeeding, agree to contraception use, and have good organ function. Exclusions include prior PARP inhibitor treatment, certain small tumors, significant other diseases or unresolved toxicities from past treatments.
What is being tested?
The study tests Niraparib given alongside standard postoperative radiation therapy in patients with triple negative breast cancer. It aims to see if this combination can improve outcomes compared to radiation alone.
What are the potential side effects?
Niraparib may cause blood disorders like anemia or low platelets, fatigue, nausea, digestive issues, and could affect fertility. Radiation therapy might lead to skin changes at the treated site, tiredness and swelling of the breast area.
