HUTCHMED Highlights SACHI Phase III Study Data Presented at the 2025 ASCO Annual Meeting
— The all-oral chemotherapy-free combination of savolitinib plus osimertinib demonstrated significant PFS benefit with a favorable safety profile in the SACHI Phase III China study — — Webcast to be held at 8:30 am HKT on Tuesday, June 3 to discuss the data presented — HONG KONG and SHANGHAI and FLORHAM PARK, N.J., June 02, 2025 (GLOBE NEWSWIRE) -- HUTCHMED (China) Limited ('HUTCHMED') (Nasdaq/AIM:HCM; HKEX:13) announces primary results from the interim analysis of the SACHI Phase III study. These results were presented in a late-breaking oral presentation on Sunday, June 1, 2025, during the American Society of Clinical Oncology ('ASCO') Annual Meeting in Chicago, USA. SACHI is a Phase III study of the savolitinib and osimertinib combination for the treatment of patients with locally advanced or metastatic epidermal growth factor receptor ('EGFR') mutation-positive non-small cell lung cancer ('NSCLC') with MET amplification after disease progression on first-line EGFR inhibitor therapy ( identifier NCT05015608). Title: Savolitinib combined with osimertinib versus chemotherapy in EGFR-mutant and MET-amplification advanced NSCLC after disease progression on EGFR tyrosine kinase inhibitor: Results from a randomized Phase III SACHI study Lead Author: Shun Lu, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China Session: Oral Abstract Session: Lung Cancer - Non-Small Cell Metastatic Abstract Number: LBA8505 Date & Time: Sunday, June 1, 2025, 8:00 AM Central Daylight Time Location: Arie Crown Theater Prof. Shun Lu, Chief of the Shanghai Lung Cancer Center at Shanghai Chest Hospital, School of Medicine, Shanghai Jiaotong University, and Principal Investigator of the SACHI study, said, 'The results from the SACHI Phase III study represent a significant advancement in the treatment of EGFR mutation-positive NSCLC with MET amplification. The savolitinib and osimertinib combination demonstrates promising efficacy in patients who have progressed on prior EGFR inhibitor therapy. These findings highlight the potential of this novel, chemotherapy-free combination to enable a continued oral regimen, offering a convenient and well-tolerated treatment option that addresses critical unmet needs for patients with this challenging disease.' The event will be held in English and can be accessed via A replay will also be available on the website shortly after the event. As of the interim analysis data cut-off of August 30, 2024, a total of 211 patients were randomized to receive the savolitinib and osimertinib combination or chemotherapy. In the intention to treat (ITT) population, the median progression-free survival ('PFS') assessed by investigator was 8.2 months with savolitinib plus osimertinib, compared to 4.5 months with chemotherapy (hazard ratio ['HR'] 0.34; 95% confidence interval ['CI'] 0.23-0.49; p < 0.0001). The independent review committee ('IRC') assessed median PFS was 7.2 months vs 4.2 months, respectively (HR 0.40; 95% CI 0.28-0.59; p < 0.0001). The investigator-assessed objective response rate (ORR) was 58% in the savolitinib plus osimertinib group compared to 34% for patients in the chemotherapy group. The disease control rate (DCR) was 89% vs 67% and the median duration of response (DoR) was 8.4 months vs 3.2 months, respectively. Overall survival was not mature at the time of the interim analysis. Efficacy outcomes in the third-generation EGFR tyrosine kinase inhibitor ('TKI')–treated patients were comparable with those in the intention-to-treat and third-generation EGFR-TKI–naïve populations. In the third generation EGFR-TKI–treated subgroup, the investigator-assessed and IRC-assessed median PFS were highly consistent, both at 6.9 vs 3.0 months (HR 0.32; p < 0.0001). The safety profile of the savolitinib and osimertinib combination was tolerable and no new safety signals were observed. Treatment-emergent adverse events of Grade 3 or above occurred in 57% of patients in the savolitinib plus osimertinib group compared to 57% for patients in the chemotherapy group, suggesting a favorable safety profile. In January 2025, the Independent Data Monitoring Committee (IDMC) of SACHI has considered that the study has met the pre-defined primary endpoint of PFS in a planned interim analysis and as a result, enrollment into the study has concluded. Supported by data from SACHI, a New Drug Application (NDA) for the combination of savolitinib and osimertinib for the treatment of patients with locally advanced or metastatic EGFR mutation-positive NSCLC with MET amplification after disease progression on first-line EGFR inhibitor therapy has been accepted and granted priority review by the China National Medical Products Administration (NMPA). About Savolitinib Savolitinib is an oral, potent, and highly selective MET TKI that has demonstrated clinical activity in advanced solid tumors. MET is a tyrosine kinase receptor that has an essential role in normal cell development. Savolitinib 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. MET overexpression and/or amplification can lead to tumor growth and the metastatic progression of cancer cells, and is a known mechanism of acquired resistance to EGFR TKIs. The prevalence of MET depends on the sample type, detection method and assay cut-off used. Savolitinib is approved in China and is marketed under the brand name ORPATHYS® by our partner, AstraZeneca, for the treatment of adult patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alteration, representing the first selective MET inhibitor approved in China. It has been included in the National Reimbursement Drug List of China (NRDL) since March 2023. It is currently under clinical development for multiple tumor types, including lung, kidney, and gastric cancers as a single treatment and in combination with other medicines. 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 three medicines marketed in China, the first of which is also approved around the world including in the US, Europe and Japan.

China's HER2-Targeted ADC Trastuzumab Rezetecan Gains NMPA Approval for HER2-Mutant NSCLC
SHANGHAI, May 29, 2025 /PRNewswire/ -- The National Medical Products Administration has recently granted approval for Trastuzumab rezetecan, China's first domestically developed antibody-drug conjugate (ADC), for treatment of adult patients with unresectable locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring activating HER2 (ERBB2) mutations who have previously received at least one systemic therapy. The approval of Trastuzumab rezetecan was based on the pivotal HORIZON-Lung study led by Professor Lu Shun at Shanghai Chest Hospital, which demonstrated groundbreaking efficacy in HER2-mutant locally advanced or metastatic NSCLC patients who have received prior systemic therapy. The trial achieved a median follow-up of 14.2 months, an IRC-confirmed objective response rate (ORR) of 74.5%, and a median progression-free survival (mPFS) of 11.5 months—thereby doubling the efficacy of conventional treatments. In addition, Trastuzumab rezetecan significantly reduced the toxicity risks typically associated with conventional ADCs. These results have redefined global benchmarks for ADC research and garnered significant attention from the international scientific community. Trastuzumab rezetecan has achieved breakthroughs in both efficacy and safety through pioneering molecular design from the ground up, a milestone made possible by Hengrui Pharmaceuticals' decade-long development of its ADC R&D platform, the Hengrui Rapid Modular ADC Platform (HRMAP). HRMAP enables end-to-end capabilities spanning molecular design, preclinical optimization, and clinical translation. To date, Hengrui has advanced over 10 differentiated ADC candidates into clinical development, including Trastuzumab rezetecan, its flagship HER2-targeted ADC therapy. Shun Lu, MD, PhD, Director of oncology department (Shanghai Lung Tumor Clinical Medical Center)，China, and principal investigator of Horizon-Lung, said, "the HORIZON-Lung study validates Trastuzumab rezetecan as a transformative therapy for HER2-mutant NSCLC, addressing a critical unmet need for advanced HER2-driven NSCLC patients in China. Grounded in epidemiological data that accurately reflect China's NSCLC epidemiological landscape, this therapeutic advance not only provides a novel treatment option for patients, but also heralds China's emergence as a pioneering force in shaping the global ADC landscape for precision oncology. Beyond its established efficacy in lung cancer, Trastuzumab rezetecan has demonstrated significant clinical advances across multiple tumor types, with eight additional indications—including breast cancer, colorectal cancer, gastric cancer, biliary tract cancer, cervical cancer, ovarian cancer, fallopian tube cancer, and primary peritoneal cancer—receiving Breakthrough Therapy Designation (BTD) from China's National Medical Products Administration (NMPA).
