HUTCHMED Highlights Presentations at the 2024 ASCO Annual Meeting

HONG KONG and SHANGHAI, China and FLORHAM PARK, N.J., May 23, 2024 (GLOBE NEWSWIRE) -- 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 Society of Clinical Oncology (“ASCO”) Annual Meeting, taking place May 31 – June 4, 2024 in Chicago, IL and online.Results will be presented from the registration Phase II study of fruquintinib combined with sintilimab in 98 second-line or above patients with endometrial cancer (“EMC”) with pMMR status by central laboratory analysis, which supported the New Drug Application (NDA) filed in China. The primary endpoint was objective response rate (“ORR”) per RECIST v1.1, assessed by an independent review committee. The combination showed meaningful efficacy improvements in advanced EMC patients with pMMR status, regardless of prior bevacizumab treatment, with a manageable safety profile. The median follow-up time was 15.7 months. The ORR in 87 efficacy evaluable patients was 35.6% including two complete responses. Disease control rate (“DCR”) was 88.5%, and duration of response was not reached, with 80.7% remaining in response after nine months. Amongst the 98 patients, median progression-free survival (PFS) was 9.5 months, and median overall survival (OS) was 21.3 months. Further details are available in the abstract link below.

Following the initial data of the FRUTIGA Phase III study of fruquintinib in second-line gastric cancer published during the February 2024 ASCO Plenary Series session, further updated efficacy data in key subgroups, and quality of life data will be presented at this year’s ASCO annual meeting. In addition, further data from the FRESCO and FRESCO-2 Phase III colorectal cancer studies, the study of surufatinib combinations in small cell lung cancer, and initial clinical data for the ERK1/2 inhibitor HMPL-295 will be presented.

*Forward-Looking Statements *

This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. 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, surufatinib and HMPL-295, the further clinical development for fruquintinib, surufatinib and HMPL-295, its expectations as to whether any studies on fruquintinib, surufatinib and HMPL-295, 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, surufatinib and HMPL-295, 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, surufatinib and HMPL-295 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.
