HUTCHMED Highlights Data to be Presented at AACR Congress 2024

Hong Kong, Shanghai & Florham Park, NJ - Friday, April 5, 2024: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM:HCM; HKEX:13) today announces that new and updated data from several studies of compounds discovered by HUTCHMED will be presented at the upcoming American Association of Cancer Research ("AACR") Annual Meeting 2024, taking place on April 5-10, 2024 in San Diego, California.

Initial preclinical data will be presented for HMPL-506, a novel, highly potent and differentiated menin-MLL inhibitor for the treatment of certain types of acute leukemia. Compared with five other menin inhibitors in clinical development, HMPL-506 showed the stronger inhibitory potency in MLL-rearranged and NPM1 mutant leukemia cell line models. Furthermore, HMPL-506  in combination with azacytidine, venetoclax or gilteritinib synergistically improved the anti-tumor effect against MLL-rearranged leukemias both in vitro and in vivo. The investigational drug candidate displayed favorable pharmacokinetic profiles, high selectivity and low risk of cardiac toxicity. A Phase I study of HMPL-506 is planned for the second half of 2024.

Initial preclinical data will also be presented for HMPL-A067 (HMA800067), a novel CD38-targeting antibody-drug conjugate (ADC) in which daratumumab was conjugated with cytotoxic payload Monomethyl auristatin E (MMAE) via a novel linker. It demonstrated significant superior anti-tumor activity to daratumumab, including  in several B-cell malignancies models with resistance to daratumumab treatment.

Other presentations include preclinical data on the ERK 1/2 inhibitor, HMPL-295; early clinical data on the Syk inhibitor, sovleplenib, in lymphoma patients; additional clinical data from global studies of VEGFR inhibitor, fruquintinib, and MET inhibitor, savolitinib; and several investigator-initiated studies of fruquintinib and VEGFR/CSF-1R/FGFR inhibitor, surufatinib.

Details of the presentations are as follows:

These forward-looking statements reflect HUTCHMED's current expectations regarding future events, including but not limited to its expectations regarding the therapeutic potential of fruquintinib, savolitinib, surufatinib, sovleplenib, HMPL-295, HMPL-506 and HMA800067, the further clinical development for fruquintinib, savolitinib, surufatinib, sovleplenib, HMPL-295, HMPL-506 and HMA800067, its expectations as to whether any studies on fruquintinib, savolitinib, surufatinib, sovleplenib, HMPL-295, HMPL-506 and HMA800067 would meet their primary or secondary endpoints, and its expectations as to the timing of the completion and the release of results from such studies. Such risks and uncertainties include, among other things, assumptions regarding enrollment rates and the timing and availability of subjects meeting a study's inclusion and exclusion criteria; changes to clinical protocols or regulatory requirements; unexpected adverse events or safety issues; the ability of fruquintinib, savolitinib, surufatinib, sovleplenib, HMPL-295, HMPL-506 and HMA800067, including as combination therapies, to meet the primary or secondary endpoint of a study, to obtain regulatory approval in different jurisdictions and to gain commercial acceptance after obtaining regulatory approval; the potential markets of fruquintinib, savolitinib, surufatinib, sovleplenib, HMPL-295, HMPL-506 and HMA800067 for a targeted indication, and the sufficiency of funding. In addition, as certain studies rely on the use of nab-paclitaxel, sintilimab, toripalimab, pemetrexed, platinum, etoposide or cisplatin as combination therapeutics, such risks and uncertainties include assumptions regarding their safety, efficacy, supply and continued regulatory approval. Existing and prospective investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
