Official title
A Phase I/II Study of the SV-BR-1-GM Regimen in HLA Matched Metastatic Breast Cancer Patients in Combination With Pembrolizumab
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I/II trial studies the side effects of a breast cancer vaccine (SV-BR-1-GM) and how well it works in combination with pembrolizumab for the treatment of breast cancer that is persistent, has come back (recurrent), or has spread to other places in the body (metastatic). Breast cancer vaccine SV-BR-1-GM is a human breast cancer cell line that has been genetically engineered to produce a substance called "GM-CSF" (granulocyte-macrophage colony stimulating factor) which occurs naturally in the body. GM-CSF is normally produced by white blood cells and helps the body develop immunity to disease-causing germs. 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. Anti-cancer drugs such as cyclophosphamide may help boost the immune response. Interferon alpha 2b may help stimulate the immune system to fight cancer. This trial may help doctors see whether SV-BR-1-GM injections help boost the immune system and/or help control or help shrink breast cancer along with the other drugs that also boost the immune system.
