Antibody-drug conjugates in solid tumors; new strategy for cancer therapy

Abstract

Antibody-drug conjugates (ADCs) have emerged as a novel class of anticancer treatment. ADCs are composed of three parts: a monoclonal antibody, a linker and a payload. A monoclonal antibody binds to the specific antigen present at the cancer cells, allowing selective delivery of the cytotoxic agents to the tumor site. Several ADCs are approved by the US Food and Drug Administration for the treatment of hematologic cancers and solid tumors with clinically meaningful survival benefit. However, the development of ADCs faces a lot of challenges and there is a need to get better understanding of ADCs in order to improve patient outcomes. Here, we briefly discuss the structure and mechanism of ADCs, as well as the clinical data of current approved ADCs in solid tumors.

Keywords: antibody-drug conjugate; solid tumors; targeted cancer therapy.
