HUTCHMED (China) Limited announced 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, 2024 to 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 RECST 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 FRUTGA 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 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.
