About this study

This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. There is some evidence from previous clinical trials that people who have a MammaPrint High 2 Risk result may be more likely to respond to chemotherapy and immunotherapy. Adding durvalumab to usual chemotherapy may be able to prevent the cancer from returning for patients with MP2 stage II-III hormone receptor positive, HER2 negative breast cancer.

You may qualify if…

✓ STEP 1: REGISTRATION (SCREENING): Participants must have histologically confirmed estrogen receptor (ER) positive and/or progesterone receptor (PR) positive (hormone receptor positive) and HER2 negative breast cancer, as per American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines
✓ NOTE: Participants with HER2 positive disease by ASCO CAP guidelines are ineligible. HER2 negative and HER2 low or equivocal cases as per ASCO CAP guidelines that do not receive HER2 targeted therapy are eligible
✓ STEP 1: REGISTRATION (SCREENING): Participants must have clinical stage II or III breast cancer
✓ NOTE: Participants with inflammatory breast cancer are eligible
✓ NOTE: Participants with occult (i.e. undetectable) primary breast cancer with axillary nodal involvement are not eligible, as MammaPrint testing has not been validated on tissue obtained from an axillary lymph node
✓ STEP 1: REGISTRATION (SCREENING): Participants must not have metastatic disease (i.e., must be clinically M0 or Mx) Systemic staging studies with imaging should follow routine practice as per National Comprehensive Cancer Network (NCCN) and ASCO guidelines
✓ STEP 1: REGISTRATION (SCREENING): Participants must not have locally recurrent breast cancer
✓ STEP 1: REGISTRATION (SCREENING): Participants with multifocal disease in the same breast or synchronous bilateral primary tumors are eligible, however, all tumors that are biopsied must be hormone receptor positive and HER2 negative per ASCO CAP guidelines and at least one of the tumors must be MammaPrint High-2. MammaPrint can be performed sequentially on biopsies as it is sufficient to have MammaPrint High 2 status on at least one of the lesions
