Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Study has three parts:
1. Neoadjuvant phase (immune-conditioning phase): patients will receive 1 dose of dostarlimab + niraparib from day -14 prior to radiotherapy (up to 48h prior to radiotherapy (RT) in Cohort A and until RT in Cohort B).
2. Concurrent phase (radiosensitization): patients will receive definitive radiotherapy (70Gy in 35 fractions) with concurrent cisplatin (Cohort A) or with concurrent niraparib (Cohort B).
3. Maintenance: Following radiotherapy, patients will receive adjuvant dostarlimab plus niraparib until week 48 (37 cycles) in both cohorts.
