— Approval based on Phase III SACHI Trial results which showed a 66% reduced risk of progression or death as compared to platinum-based chemotherapy —

— The only all-oral combination treatment option for these patients —

— Consistent benefit regardless of first-line EGFR inhibitor therapy —

Hong Kong, Shanghai & Florham Park, NJ —  Monday, June 30, 2025: HUTCHMED (China) Limited (“HUTCHMED”) (Nasdaq/AIM:​HCM; HKEX:​13) today announces that the New Drug Application (“NDA”) for the combination of ORPATHYS^® (savolitinib) and TAGRISSO^® (osimertinib) has been granted approval by the China National Medical Products Administration (“NMPA”) for the treatment of patients with locally advanced or metastatic epidermal growth factor receptor (“EGFR”) mutation-positive non-squamous non-small cell lung cancer (“NSCLC”) with MET amplification after disease progression on EGFR tyrosine kinase inhibitor (“TKI”) therapy. ORPATHYS^® is an oral, potent and highly selective MET TKI. TAGRISSO^® is a third-generation, irreversible EGFR TKI. This approval also triggers a US$11 million milestone payment from AstraZeneca, which markets both ORPATHYS^® and TAGRISSO^® in China.

ORPATHYS^® was the first selective MET inhibitor approved in China, indicated for adult patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alteration. This new approval by the NMPA was based on data from the SACHI Phase III trial of the ORPATHYS^® and TAGRISSO^® combination (NCT05015608), having met the pre-defined primary endpoint of progression-free survival (“PFS”) in a pre-planned interim analysis. Primary results were presented at the American Society of Clinical Oncology (“ASCO”) Annual Meeting in June 2025. In 2024 the NMPA designated the combination as a Breakthrough Therapy, and in 2025 it granted the NDA Priority Review.

Professor 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 trial, said, “The approval of the ORPATHYS^® and TAGRISSO^® combination is a significant milestone in addressing the complex challenges of lung cancer treatment in China, where the EGFR mutation is common amongst NSCLC patients. For patients who develop MET amplification after progressing on EGFR inhibitors, the combination offers a continued all-oral, chemotherapy-free approach to tackle a critical resistance mechanism. As a researcher and clinician, I am excited about the opportunity to offer this targeted therapy to patients, improving their treatment outcomes and quality of life through innovative research.”

“The NMPA approval marks an important step forward in our mission to address MET-driven progression following first-line EGFR-inhibitor therapy in NSCLC patients.” said Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED. “Our collaboration with AstraZeneca, built on a shared vision to transform oncology care, has been crucial in reaching this achievement. We are committed to advancing this partnership, continuing our research into further treatment settings, and bringing this innovative combination to patients in China and beyond.”

Ms Mary Guan, General Manager of AstraZeneca China Oncology Business, said: “This milestone marks the third indication of ORPATHYS^® approved in China, bringing a new treatment option to lung cancer patients who develop MET amplification after progressing on EGFR inhibitor therapy. Through our partnership with HUTCHMED, we are committed to expanding the reach of the ORPATHYS^® and TAGRISSO^® combination to address progression on first-line therapy and help even more patients with this form of lung cancer.”

In the intention to treat (ITT) population of the SACHI trial, the ORPATHYS^® and TAGRISSO^® combination reduced the risk of disease progression by 66% with a median PFS of 8.2 months, compared to 4.5 months for chemotherapy, as assessed by investigators. The independent review committee (IRC) also reported a 60% risk reduction in disease progression, with a median PFS of 7.2 months versus 4.2 months, respectively. The safety profile of the ORPATHYS^® and TAGRISSO^® 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 both the ORPATHYS^® plus TAGRISSO^® group and the chemotherapy group, suggesting a favorable safety profile.

About NSCLC and MET aberrations

Lung cancer is the leading cause of cancer death, accounting for about one-fifth of all cancer deaths.^[1] Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% classified as NSCLC.^[2] The majority of NSCLC patients (approximately 75%) are diagnosed with advanced disease, and approximately 10-15% of NSCLC patients in the US and Europe and 30-40% of patients in Asia have EGFR-mutated (“EGFRm”) NSCLC.^{[3],[4],[5],[6]}

MET is a tyrosine kinase receptor that has an essential role in normal cell development. MET overexpression and/or amplification can lead to tumor growth and the metastatic progression of cancer cells, and is one of the mechanisms of acquired resistance to EGFR TKI for metastatic EGFRm NSCLC.^[7],[8]

About ORPATHYS^®

ORPATHYS^® (savolitinib) is an oral, potent and highly selective MET TKI 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.

ORPATHYS^® is approved in China and is marketed by 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 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 TAGRISSO^®

TAGRISSO^® (osimertinib) is a third-generation, irreversible EGFR-TKI with proven clinical activity in NSCLC, including against central nervous system (CNS) metastases. TAGRISSO^® (40mg and 80mg once-daily oral tablets) has been used to treat nearly 800,000 patients across its indications worldwide and AstraZeneca continues to explore TAGRISSO^® as a treatment for patients across multiple stages of EGFRm NSCLC.

There is an extensive body of evidence supporting the use of TAGRISSO^® as standard of care in EGFRm NSCLC. TAGRISSO^® improved patient outcomes in early-stage disease in the ADAURA Phase III trial, locally advanced disease in the LAURA Phase III trial, late-stage disease in the FLAURA Phase III trial, and with chemotherapy in the FLAURA2 Phase III trial.

About ORPATHYS^® and TAGRISSO^® Combination Development in EGFR-mutated NSCLC

Among patients who experience disease progression following treatment with a third-generation EGFR TKI, approximately 15-50% present with MET aberration, depending on the sample type, detection method and assay cut-off used. TAGRISSO^® is a third-generation, irreversible EGFR-TKI with proven clinical activity in NSCLC, including against central nervous system metastases. Treatment with ORPATHYS^® in combination with TAGRISSO^® has been studied extensively in these patients in the TATTON (NCT02143466) and SAVANNAH (NCT03778229) studies. The encouraging results led to the initiation of several Phase III trials in this setting including the SACHI trial in China (NCT05015608) and the global SAFFRON trial (NCT05261399), as well as the SANOVO trial in China (NCT05009836).

This combination represents a promising chemotherapy-free oral treatment strategy to address mechanisms of resistance in this advanced setting. Positive data from the SACHI randomized Phase III trial led to the filing of a second NDA in China. Strong data from the SAVANNAH single-arm Phase II study was recently presented at the European Lung Cancer Congress (ELCC) in March 2025 demonstrated high, clinically meaningful and durable objective response rate (ORR), with consistent safety results. The SAFFRON randomized Phase III trial is progressing. Following AstraZeneca’s consultation with the US Food and Drug Administration (“FDA”), we look forward to completing the SAFFRON trial as soon as possible to support potential US and other global registration filings.

SACHI: The SACHI China Phase III trial met the primary endpoint of PFS during its interim analysis towards the end of 2024 and a NDA was accepted and granted Breakthrough Therapy Designation and Priority Review status in China in December 2024. SACHI evaluated the combination of ORPATHYS^® and TAGRISSO^® for the treatment of patients with EGFRm, MET-amplified locally advanced or metastatic NSCLC after progression on EGFR TKI compared to platinum-based doublet chemotherapy. Results were presented at the ASCO Annual Meeting in June 2025.

SAFFRON: In 2023, ORPATHYS^® and TAGRISSO^® received Fast Track Designation from the US FDA in this setting. The global SAFFRON Phase III trial is currently ongoing to assess the ORPATHYS^® plus TAGRISSO^® combination versus platinum-based doublet chemotherapy in patients with EGFRm, MET-overexpressed and/or amplified, locally advanced or metastatic NSCLC following progression on treatment with TAGRISSO^®. Patients are being prospectively selected using the high MET level cut-off identified in SAVANNAH.

Hong Kong, Shanghai & Florham Park, NJ — Thursday, June 5, 2025: HUTCHMED (China) Limited (“HUTCHMED”) (Nasdaq/AIM:​HCM; HKEX:​13) and Innovent Biologics, Inc. (“Innovent”) (HKEX: 01801) today jointly announce that the New Drug Application (“NDA”) for the combination of fruquintinib and sintilimab for the treatment of patients with locally advanced or metastatic renal cell carcinoma who have failed prior treatment with one tyrosine kinase inhibitor (“TKI”) has been accepted for review by the China National Medical Products Administration (“NMPA”).

The NDA is supported by data from FRUSICA-2, a randomized, open-label, active-controlled registration study evaluating the efficacy and safety of fruquintinib in combination with sintilimab versus axitinib or everolimus monotherapy for the second-line treatment of advanced renal cell carcinoma. The study has met its primary endpoint of progression free survival (“PFS”), as assessed by blinded independent central review (BICR) according to RECIST 1.1 criteria. The combination also demonstrated improvements in secondary endpoints including objective response rate (“ORR”) and duration of response (“DoR”). The safety profile was tolerable and no new safety signals were observed. Data from FRUSICA-2 will be submitted for presentation at an upcoming scientific conference. Additional details may be found at clinicaltrials.gov, using identifier NCT05522231.

“Kidney cancer continues to pose significant challenges in China, with limited treatment options for patients who fail first-line therapies. Submitting this NDA for the fruquintinib and sintilimab combination for advanced renal cell carcinoma marks an important step in our efforts to address this unmet need,” said Dr Michael Shi, Head of R&D and Chief Medical Officer of HUTCHMED. “We are dedicated to making this combination therapy available to patients with renal cell carcinoma. At the same time, through ongoing research, we remain focused on exploring the full potential of this combination, as well as advancing our broader pipeline across multiple cancer types, to provide more patients with new and effective treatment options.”

“The NDA acceptance of sintilimab and fruquintinib combination represents a significant step toward providing a more effective second line treatment option for patients with advanced renal cell carcinoma in China,” said Dr Hui Zhou, Senior Vice President of Innovent. “Our PD-1 inhibitor, sintilimab (TYVYT^®), has solidified its position as a cornerstone of immuno-oncology (IO) therapy with this NDA as its 10^th indication, marking a meaningful milestone in lifecycle management and clinical value optimization.”

In December 2024, the combination of fruquintinib and sintilimab received conditional approval from the China NMPA for the treatment of patients with advanced mismatch repair proficient (“pMMR”) endometrial cancer who have failed prior systemic therapy and are not candidates for curative surgery or radiation, based on data from the FRUSICA-1 study (NCT03903705).

About Kidney Cancer and Renal Cell Carcinoma

It is estimated that approximately 435,000 new patients were diagnosed with kidney cancer worldwide in 2022.^[1] In China, an estimated 74,000 new patients were diagnosed with kidney cancer in 2022.^[2] Approximately 90% of kidney tumors are renal cell carcinoma.

About Fruquintinib

Fruquintinib is a selective oral inhibitor of all three vascular endothelial growth factor receptors (“VEGFR”) -1, -2 and -3. VEGFR inhibitors play a pivotal role in inhibiting tumor angiogenesis. Fruquintinib was designed to have enhanced selectivity that limits off-target kinase activity, allowing for drug exposure that achieves sustained target inhibition and flexibility for potential use as part of a combination therapy.^[3]

About Fruquintinib Approvals

Fruquintinib is co-developed and co-commercialized in China by HUTCHMED and Eli Lilly and Company under the brand name ELUNATE^®. It is approved for the treatment of patients with metastatic colorectal cancer who have previously received fluoropyrimidine, oxaliplatin and irinotecan-based chemotherapy, and those who have previously received or are not suitable to receive anti-VEGF therapy or anti-epidermal growth factor receptor (EGFR) therapy (RAS wild-type) in China. It was included in the China National Reimbursement Drug List (NRDL) in January 2020. Since its launch in China, over 100,000 patients with colorectal cancer have been treated with fruquintinib.

The combination of ELUNATE^® (fruquintinib) and TYVYT^® (sintilimab injection) has conditional approval in China for the treatment of patients with advanced pMMR endometrial cancer who have failed prior systemic therapy and are not candidates for curative surgery or radiation.

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^®. Fruquintinib received approval for the treatment of previously treated metastatic colorectal cancer in the US, Europe, Japan and many other countries around the world.

The safety and efficacy of fruquintinib for the following investigational uses have not been established and there is no guarantee that it will receive health authority approval or become commercially available in any country for the uses being investigated:

About Fruquintinib for Second-line Treatment of Renal Cell Carcinoma

Single-agent targeted therapy continues to be one of the primary choices for first-line treatment of advanced renal cell carcinoma in China. Notably, advanced renal cell carcinoma patients who have experienced failure with single-agent targeted therapy previously still indicate an unmet medical need.

Results from a proof-of-concept Phase Ib/II study of fruquintinib plus sintilimab were published in Targeted Oncology in January 2025. The combination showed promising efficacy and a tolerable safety profile in this setting. At the data cutoff of October 9, 2024, all 20 enrolled previously treated patients were evaluable for efficacy, with a median follow-up duration of 45.7 months. The confirmed ORR was 60.0% and DCR was 85.0%. Median DoR was 13.9 months and median PFS was 15.9 months. Overall survival (“OS”) was not reached, and the 36-month OS rate was 58.3%.^[4]

About Sintilimab

Sintilimab, marketed as TYVYT^® (sintilimab injection) in China, is a PD-1 immunoglobulin G4 monoclonal antibody co-developed and co-commercialized by Innovent and Eli Lilly and Company, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells. ^[5]

In China, sintilimab has been approved and included in the updated NRDL for seven indications. The updated NRDL reimbursement scope for TYVYT^® (sintilimab injection) includes:

• For the treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy;
• For the first-line treatment of unresectable locally advanced or metastatic non-squamous non-small cell lung cancer lacking EGFR or ALK driver gene mutations;

— 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, Shanghai & Florham Park, NJ — Monday, June 2, 2025: 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 (clinicaltrials.gov identifier NCT05015608).

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.”

HUTCHMED will host a webcast to discuss the data presented at the ASCO Annual Meeting at 8:30 -9:00 am HKT on Tuesday, June 3, 2025 (8:30 – 9:00 pm EDT on June 2, 2025). The event will be held in English and can be accessed via www.hutch-med.com/event. 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.
