BreastVAX: Radiation Boost to Enhance Immune Checkpoint Blockade Therapy (NCT04454528)
Preoperative Use of Radiation Boost to Enhance Effectiveness of Immune Checkpoint Blockade Therapy in Operable Breast Cancer
🩺 Plain-English Summary (8th-Grade Level)
The primary objective is to determine the feasibility of combining pembrolizumab with a single fraction radiation boost in patients with early/ operable breast cancer. The secondary objectives are to assess clinical response on pre- and post-treatment clinical, imaging, and histology exams, and to assess immune response on pre and post treatment blood and tissue samples by tracking change in Ki67 + CD8 T cells in peripheral blood and in extent of tumor infiltrating lymphocytes. A clinically significant partial response is defined as \>30% tumor shrinkage post-clinical trial intervention.
