SGT-53, Carboplatin, and Pembrolizumab for the Treatment of Metastatic Triple Negative Inflammatory Breast Cancer

This phase I trial studies the effect of SGT-53, carboplatin, and pembrolizumab in treating patients with triple negative inflammatory breast that has spread to other parts of the body (metastatic). SGT-53 is a gene therapy that changes the deoxyribonucleic acid (DNA) of patients' tumor cells to make it easier for the immune system to recognize them. SGT-53 targets the TP53 gene, which is frequently mutated in IBC cells. Chemotherapy drugs, such as carboplatin, 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving SGT-53, pembrolizumab, and carboplatin may help the control the disease in patients with triple negative inflammatory breast cancer.
