The purpose of this study is to determine the effects of an immune therapy drug called pembrolizumab when combined with standard-of-care, preoperative chemotherapy with HER2-directed therapy in patients with stage II/III HER2-positive, invasive, unilateral breast cancer prior to standard-of-care breast surgery. Participants will be randomly assigned to one of three study groups. Group 1 will receive standard-of-care drugs (trastuzumab, pertuzumab, and paclitaxel) before surgery. Group 2 will receive the standard of care drugs (trastuzumab, pertuzumab, and paclitaxel) plus immune therapy with pembrolizumab (study drug). Group 3 will receive the standard-of-care drugs (trastuzumab and paclitaxel) plus immune therapy with pembrolizumab (study drug).
Pembrolizumab is approved by the U.S. Food and Drug Administration (FDA) for various types of cancers, but it is not approved for the treatment of breast cancer. Pertuzumab, trastuzumab, and paclitaxel in combination are approved by the FDA for the treatment of HER2-positive breast cancer. However, the use of the pertuzumab, paclitaxel, trastuzumab, and pembrolizumab in combination (or trastuzumab, pembrolizumab, and paclitaxel) have not been approved by the FDA.
