EGFR inhibitor CO-1686
An orally available small molecule, irreversible inhibitor of epidermal growth factor receptor (EGFR) with potential antineoplastic activity. EGFR inhibitor CO-1686 binds to and inhibits mutant forms of EGFR, including T790M, thereby leading to cell death of resistant tumor cells. Compared to other EGFR inhibitors, CO-1686 inhibits T790M, a secondary acquired resistance mutation, as well as other mutant EGFRs and may have therapeutic benefits in tumors with T790M-mediated resistance to other EGFR tyrosine kinase inhibitors. This agent shows minimal activity against wild-type EGFR, hence does not cause certain dose-limiting toxicities. Check for active clinical trials or closed clinical trials using this agent.
