Core Insights - HUTCHMED is presenting new and updated data on its compounds savolitinib, fruquintinib, and surufatinib at the AACR Annual Meeting 2025, highlighting ongoing research and development efforts in oncology [1][2]. Company Overview - HUTCHMED is an innovative, commercial-stage biopharmaceutical company focused on the discovery, development, and commercialization of targeted therapies and immunotherapies for cancer and immunological diseases [11]. - The company has successfully marketed three medicines in China, with its first drug also approved in the US, Europe, and Japan [11]. Product Information - **Savolitinib**: An oral, selective MET tyrosine kinase inhibitor developed in collaboration with AstraZeneca, approved in China for treating advanced or metastatic NSCLC with MET exon 14 skipping alterations [5][6]. - **Fruquintinib**: Undergoing clinical development for various tumor types, including colorectal cancer, and is being studied in combination with other therapies [2][5]. - **Surufatinib**: Currently in clinical trials for advanced neuroendocrine tumors and other cancers, with ongoing studies to assess its efficacy in combination with other treatments [2][3]. Clinical Trials and Research - The **SAVANNAH** study is evaluating the combination of savolitinib and osimertinib in NSCLC patients who have progressed after EGFR TKI treatment, with promising results leading to further Phase III trials [7][9]. - The **SACHI** trial has met its primary endpoint of progression-free survival, supporting the combination of savolitinib and TAGRISSO for specific NSCLC patients [9][10]. - The **SAFFRON** trial is assessing the efficacy of savolitinib plus TAGRISSO against platinum-based chemotherapy in a similar patient population [10]. Market Context - Lung cancer remains the leading cause of cancer death globally, with a significant patient population in China, where over a third of the world's lung cancer patients reside [4]. - Non-small cell lung cancer (NSCLC) accounts for approximately 80% of lung cancer cases, with a notable prevalence of EGFR mutations and MET alterations among patients [4].

Company Overview - HUTCHMED (China) Limited is an innovative, commercial-stage biopharmaceutical company focused on the discovery, development, and commercialization of targeted therapies and immunotherapies for cancer and immunological diseases [12]. Recent Developments - HUTCHMED announced new and updated data from studies of its compounds, including savolitinib, fruquintinib, and surufatinib, which will be presented at the American Association of Cancer Research (AACR) Annual Meeting 2025 [1]. - The company is actively involved in multiple clinical trials, including the SACHI and SAFFRON trials, assessing the combination of savolitinib with TAGRISSO® (osimertinib) for treating patients with advanced non-small cell lung cancer (NSCLC) [10][11]. Product Information - Savolitinib is a selective MET tyrosine kinase inhibitor developed by HUTCHMED and AstraZeneca, approved in China for treating adult patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alterations [7][6]. - Fruquintinib is being studied in various treatment regimens for metastatic colorectal cancer (mCRC), with ongoing trials evaluating its efficacy in combination with other therapies [2][3]. Market Context - Lung cancer is the leading cause of cancer death globally, with NSCLC accounting for approximately 80% of cases. A significant portion of NSCLC patients in Asia have epidermal growth factor receptor (EGFR) mutations, which are targetable by therapies like savolitinib [4][5]. - The prevalence of MET aberrations in NSCLC patients who progress after EGFR TKI treatment is notable, with studies indicating that 15-50% of these patients may present with such mutations [8][9]. Clinical Trial Highlights - The SACHI trial met its primary endpoint of progression-free survival (PFS) during its interim analysis, leading to the acceptance of a New Drug Application (NDA) in China [10]. - The SAFFRON trial is ongoing, assessing the combination of savolitinib and TAGRISSO® against platinum-based chemotherapy in a specific patient population [11]. Future Prospects - HUTCHMED is focused on expanding the clinical development of its compounds, with promising data from ongoing trials expected to support potential regulatory filings in the US and other global markets [9][11].
