HUTCHMED signed an exclusive global development and licensing agreement with a GSK subsidiary for HMPL-A830, a KRAS‑EGFR‑directed antibody‑drug conjugate, with a potential total value of up to $1.295 billion. HUTCHMED will receive $110 million upfront and can earn up to $1.185 billion in milestones plus tiered royalties; GSK receives rights outside mainland China, Hong Kong, Macau and Taiwan, while HUTCHMED retains those territories. The deal is seen as validation of the ATTC platform and foresees the start of a global Phase I program in H2 2026. The news, together with a recent conditional approval of fanregratinib in China, drove an intraday share rise of about 14% to $13.95. » More on de.investing.com
