HUTCHMED (China) Limited (Nasdaq/AIM: HCM; HKEX: 13) has entered an exclusive licensing agreement with GSK plc (NYSE/LSE: GSK) covering HMPL-A830, an experimental antibody-targeted cancer therapy expected to enter clinical development during the second half of 2026.
Under the September 3 agreement, HUTCHMED is set to receive US$110 million upfront when the transaction closes. The company could receive another US$1.185 billion through development, regulatory and commercial milestones, bringing the potential total to US$1.295 billion. GSK will also pay tiered royalties on future net sales.
The upfront payment is subject to customary closing conditions, including applicable antitrust reviews. Milestone payments depend on future clinical, regulatory and commercial achievements and are not guaranteed.
GSK will receive development and commercialization rights worldwide except in Mainland China, Hong Kong, Macau and Taiwan, where HUTCHMED will retain full rights. HUTCHMED will conduct the global Phase 1 program, after which GSK will assume responsibility for subsequent development and commercialization outside those retained territories.
HMPL-A830 is an antibody-targeted therapy conjugate, or ATTC. It combines an anti-EGFR antibody with a small-molecule inhibitor targeting KRAS, a frequently altered cancer-causing protein. The candidate is designed to deliver its KRAS inhibitor directly to EGFR-expressing tumors while simultaneously blocking EGFR and KRAS signaling.
HUTCHMED describes HMPL-A830 as a potential first-in-class therapy. Initial clinical development is expected to focus on colorectal, pancreatic and lung cancers, which commonly contain KRAS alterations. The company reported that regulatory clearances for the study were obtained in June and July 2026. No human safety or efficacy results have been announced.
“HMPL-A830 is our third drug candidate from these novel payload platforms and the first from our platform to be licensed to a global partner,” Acting CEO and CFO Johnny Cheng said.
The transaction also provides outside validation for HUTCHMED’s emerging ATTC platform. Two other candidates, HMPL-A251 and HMPL-A580, entered early clinical development in December 2025 and March 2026, respectively.
HUTCHMED reported US$1.375 billion in cash, cash equivalents and short-term investments as of June 30, 2026. First-half consolidated revenue was US$278.3 million, while net income attributable to HUTCHMED was US$15.9 million. The corresponding 2025 profit included a US$416.3 million gain from a business divestment, making the year-over-year comparison less representative of ongoing operations.
