HUTCHMED announced that it has completed an overseas licensing agreement for HMPL-A830, a KRAS-EGFR antibody-drug conjugate therapy exclusively developed with a subsidiary of GlaxoSmithKline (GSK plc). The agreement grants the GSK subsidiary exclusive rights to develop and commercialize HMPL-A830 globally, excluding mainland China, Hong Kong, Macau, and Taiwan. HUTCHMED expects to receive an upfront payment of $110 million, with potential additional payments of up to $1.185 billion upon achieving regulatory, development, and commercial sales milestones, plus tiered royalties based on net sales.
According to the company, HMPL-A830 enhances efficacy, durability, and tolerability by delivering a rat sarcoma subtype KRAS inhibitor directly to tumors expressing EGFR, thereby simultaneously blocking both EGFR and KRAS signaling pathways.
Currently, a global clinical trial testing HMPL-A830 for the treatment of unresectable advanced or metastatic solid tumors in China and the United States was initiated in September 2026. (am)
