Abstract:
The HER-3 receptor is emerging as an attractive molecule in therapeutics because of its overexpression across many human cancers and because of its role in in several compensatory processes that underlay emergence of resistance to certain cancer drugs. In this study, we present evidence of the preclinical efficacy of a novel Antibody-Drug Conjugate (ADC) targeting HER-3. It consists of a humanized HER-3 monoclonal antibody (mAb EV20), which recognizes the HER-3 extracellular domain, conjugated to different payloads (HER-3-ADC)s. In HER-3 expressing cancer cell lines, these HER-3-ADCs demonstrated a powerful, specific and target-dependent killing activity. High expression levels of HER-3 in tumor cells correlated with efficient internalization, efficacy, and cytotoxic effects in vitro. Efficacy studies demonstrated that HER-3-ADCs treatment leads to a long lasting tumor growth inhibition of cell line-based models of human head and neck, breast, pancreatic, prostatic, lung, stomach cancers and melanoma. Overall, these findings validate HER-3 as an attractive therapeutic target in multiple solid tumors and support further clinical development and application of HER-3 targeting ADCs.
