HCM HUTCHMED China Limited

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:
