Durvalumab Plus Chemotherapy Versus Chemotherapy Alone in HR Positive / HER2 Negative Stage II-III Breast Cancer

What is the Purpose of this Study?

This study focuses on individuals who have early-stage breast cancer that is hormone receptor (HR)-positive and human epidermal growth factor receptor (HER2)-negative with high risk of cancer recurrence based on MammaPrint testing (test that analyzes genes in early-stage cancer). The study aims to determine whether adding an immunotherapy drug (durvalumab) to usual chemotherapy before surgery can lower the chance of breast cancer returning. The addition of durvalumab to the usual treatment could prevent the cancer from returning but may also cause side effects. Researchers will evaluate whether the study drug extends the life of patients and/or prevents the tumor from coming back as compared to the usual approach. The usual approach for people who are not in a study is treatment with chemotherapy, surgery and hormone therapy. Participants in this study will be assigned to 1 of 2 groups. Group 1 will receive the usual combination of 3 chemotherapy drugs (paclitaxel, cyclophosphamide, and doxorubicin) used to treat this type of cancer. Group 2 will receive durvalumab plus the usual combination of 3 chemotherapy drugs (paclitaxel, cyclophosphamide, and doxorubicin).


Eligibility
