Activated T cells armed with bispecific antibodies kill tumor targets

Curr Opin Hematol. 2015 Nov;22(6):476-83. doi: 10.1097/MOH.0000000000000176.

Abstract

Purpose of review: Adoptive T-cell therapy has become one of the most exciting fields of cancer therapy in the past few years. In this article, we describe a method which combines adoptive T-cell therapy with antibody therapy by arming T cells from cord blood, normal patients, and cancer patients with bispecific antibodies capable of binding to tumor-associated antigens on one side of the bispecific antibody construct and T cells on another side of the construct. This approach redirects T cells against tumor cells in a non-MHC-restricted manner.

Recent findings: Various methods for manipulating the immune system including check-point inhibitors, chimeric antigen receptor T cells, and bispecific antibodies have shown promising activity in treating both hematological malignancies and solid tumors with excellent success. In recent studies, activated T cells armed with bispecific antibodies have shown good preclinical activity, safety, and promising efficacy in the clinical trials.

Summary: Activated T cells armed with bispecific antibodies represent a promising treatment for cancer immunotherapy.
