Nontoxic approaches are needed to improve overall survival (OS) and progression-free survival (PFS) for high-risk breast cancer. Combination immunotherapy (IT) consisting of activated T cells (ATC), interleukin-2 (IL-2), and CTL (GM-CSF) was given after peripheral blood stem cell transplant (PBSCT). There were no major toxicities and there appear to be improvements in OS and PFS over historical controls. In order to develop specific cytotoxic T lymphocytes (CTL), we combined ATC with the use of bispecific antibody (BiAb). By arming ATC with anti-CD3 × anti-HER2/neu BiAb (HER2BiAb), the approach converts nonspecific ATC into HER2/neu (HER2) specific CTL. ATC remain armed, kill tumor targets for days, and produce cytokines after binding to tumor. Arming ATC with BiAbs may prove to be effective for targeting a variety of tumors with and without high-dose chemotherapy.
