Overview

This combination therapy pairs zamzetoclax, a potent and selective B-cell lymphoma 2 (BCL-2) inhibitor, with sacituzumab govitecan, a TROP-2-directed antibody-drug conjugate (ADC). Zamzetoclax (BGB-11417) is designed to promote apoptosis by inhibiting the BCL-2 protein, which is often overexpressed in various cancers to evade programmed cell death. Sacituzumab govitecan (Trodelvy) consists of a humanized monoclonal antibody targeting TROP-2 linked via a hydrolyzable linker to SN-38, a topoisomerase I inhibitor payload. The combination aims to leverage the cytotoxic effects of the ADC with the pro-apoptotic sensitization provided by the BCL-2 inhibitor, potentially overcoming resistance mechanisms in TROP-2-expressing solid tumors such as triple-negative breast cancer (TNBC), HR+/HER2- breast cancer, and small cell lung cancer (SCLC).
