HUTCHMED Highlights Clinical Data to be Presented at the ESMO Congress 2026

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 European Society for Medical Oncology (“ESMO”) Congress 2026, taking place on October 23-27, 2026, in Madrid, Spain.

Notably, results from two positive Phase III studies evaluating the savolitinib and osimertinib combination have been selected for oral presentations. Results from the global SAFFRON study will be featured in the Presidential Symposium session, while results from the SANOVO study in China will be presented in a Proffered Paper session, both highlighting important new clinical data. Having two Phase III studies featured as late-breaking abstracts underscores the potential of this all-oral, chemo-free combination to deliver meaningful advancements for patients with non-small cell lung cancer (“NSCLC”).

The SAFFRON Global Phase III Study has been selected for a Presidential Symposium oral presentation. The study evaluated the combination in patients with epidermal growth factor receptor (EGFR)-mutated NSCLC with MET overexpression or amplification following disease progression on osimertinib. The trial reported positive high-level results on August 17, 2026, demonstrating a statistically significant and clinically meaningful improvement in progression-free survival (“PFS”) and overall survival (“OS”) compared to doublet platinum-based chemotherapy.

The SANOVO China Phase III Study has been selected for a Proffered Paper oral presentation. The study evaluated the combination in previously untreated patients with locally advanced or metastatic NSCLC harboring activating EGFR mutations and MET overexpression. The trial reported positive high-level results on August 31, 2026, demonstrating a statistically significant and clinically meaningful improvement in PFS and a clinically meaningful benefit in OS versus osimertinib monotherapy.

Details of the presentations are as follows:

About Fruquintinib Fruquintinib is a selective oral inhibitor of all three vascular endothelial growth factor receptors (“VEGFR”) -1, -2 and -3. Fruquintinib is co-developed and co-commercialized in China by HUTCHMED and Eli Lilly and Company under the brand name ELUNATE ® . Takeda holds the exclusive worldwide license to further develop, commercialize, and manufacture fruquintinib outside mainland China, Hong Kong and Macau, marketing it under the brand name FRUZAQLA ® .

About Savolitinib Savolitinib is an oral, potent and highly selective MET tyrosine kinase inhibitor that has demonstrated clinical activity in advanced solid tumors. It blocks atypical activation of the MET receptor tyrosine kinase pathway that occurs because of mutations (such as exon 14 skipping alterations or other point mutations), gene amplification or protein overexpression. Savolitinib is being jointly developed by AstraZeneca and HUTCHMED, and commercialized by AstraZeneca under the brand name ORPATHYS ® .

About Surufatinib Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with VEGFRs and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells. Surufatinib is marketed in China by HUTCHMED under the brand name SULANDA ® . HUTCHMED currently retains all rights to surufatinib worldwide.

About HUTCHMED HUTCHMED (Nasdaq/AIM:HCM; HKEX:13) is an innovative, commercial-stage, biopharmaceutical company. It is committed to the discovery and global development and commercialization of targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. Since inception it has focused on bringing drug candidates from in-house discovery to patients around the world, with its first four medicines marketed in China, the first of which is also approved around the world including in the US, Europe and Japan.

Forward-Looking Statements This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the US 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 savolitinib, the further clinical development for fruquintinib, surufatinib and savolitinib, its expectations as to whether any studies on fruquintinib, surufatinib and savolitinib 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 savolitinib, 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 savolitinib for a targeted indication, and the sufficiency of funding. In addition, as certain studies rely on the use of other drug products such as sintilimab and toripalimab 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. For further discussion of these and other risks, see HUTCHMED’s filings with the US Securities and Exchange Commission, The Stock Exchange of Hong Kong Limited and on AIM.
