Overview

Cofetuzumab pelidotin is an experimental antibody-drug conjugate (ADC) designed for the treatment of cancer. It consists of a humanized anti-protein tyrosine kinase 7 (PTK7) monoclonal antibody (hu6M024, IgG1) linked via a cleavable valine-citrulline linker to auristatin-0101 (Aur0101), a potent microtubule inhibitor. The ADC selectively binds to PTK7-expressing tumor cells; upon internalization and cleavage within the cell, it releases the cytotoxic auristatin payload that disrupts microtubules and induces mitotic arrest and apoptosis. PTK7 is overexpressed in several cancers including non-small cell lung cancer (NSCLC), ovarian cancer, breast cancer—especially triple-negative breast cancer—and others. Early clinical trials have shown promising antitumor activity in these indications[1][3][5][6][7].
