Brief Summary

This phase II randomized trial is for patients with clinical stage II-III, ER and PR <10%, HER2-negative invasive breast carcinoma (triple negative breast cancer) for whom adjuvant RT is planned and pre-operative RT is deemed feasible by the treating radiation oncologist. Subjects will be randomized into arm A or B and treatment will last for 16 weeks. Both groups will receive Durvalumab 750mg IV Q2 weeks x 2 then a biopsy prior to durvalumab 1500mg IV Q4 weeks x 3 with paclitaxel and carboplatin IV weekly x 12. Arm B will receive radiation (24 Gy total) starting with the second durvalumab dose every other day (8Gy per fraction) for one week. Following treatment, subjects will receive SOC breast surgery and continue on to physician's choices SOC treatment during the 3 year follow up period.

This study hopes to explore the impact of checkpoint blockade administration with a non- anthracycline chemotherapy regimen plus RT on post-surgery pathologic complete response (pCR) rate in the breast and axilla (ypT0/Tis ypN0) following 12 weeks of treatment and surgery.

2. Clinical stage II-III by the AJCC 8th definition, any nodal status (cT2-4N0 or cT1-4N1-3), biopsies of clinically suspicious lymph nodes to confirm nodal status is encouraged.

3. Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form and in this protocol. Written informed consent and any locally required authorization obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations.

4. At least 18 years of age on the day of signing informed consent.

5. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.

6. Body weight >30kg.

7. Have provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.

8. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.

9. Have adequate organ function as defined in the following table (Table 1). Specimens must be collected within 10 days prior to the start of study treatment.

10. Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

11. Patients with multifocal, multicentric or bilateral breast cancer are permitted if all suspicious foci have been biopsied and deemed "triple negative" per criterion 1.

Male participants:

12. A male participant must agree to use a contraception as detailed in Appendix C of this protocol during the treatment period and for at least 6 months after the last dose of study treatment and refrain from donating sperm during this period.

Female participants:

13. A female participant is eligible to participate if she is not pregnant (see Appendix C), not breastfeeding, and at least one of the following conditions applies:

1. Not a woman of childbearing potential (WOCBP) as defined in Appendix C OR

2. A WOCBP who agrees to follow the contraceptive guidance in Appendix C during the treatment period and for at least 6 months after the last dose of study treatment.

Exclusion Criteria

1. A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization (see Appendix C). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

2. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX 40, CD137).

3. Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.
