The Food and Drug Administration (FDA) grants Priority Review to applications for medicines that, if approved, would offer significant improvements over available options by demonstrating safety or efficacy improvements, preventing serious conditions or enhancing patient compliance. 1 The Prescription Drug User Fee Act date, the FDA action date for its regulatory decision, is anticipated during the third quarter of 2025. Datopotamab deruxtecan was previously granted Breakthrough Therapy Designation (BTD) by the FDA for this patient population. The BLA and BTD are based on data from the TROPION-Lung05 Phase II trial and supported by data from the TROPION-Lung01 Phase III trial. In addition, the BLA is supported by data from the TROPION-PanTumor01 Phase I trial. In a pooled analysis of patients with previously treated advanced or metastatic EGFR m NSCLC in the TROPION-Lung05 and TROPION-Lung01 trials presented at the European Society for Medical Oncology (ESMO) Asia 2024 Congress, datopotamab deruxtecan demonstrated a confirmed objective response rate (ORR) of 42.7% (95% confidence interval [CI] 33.6-52.2) as assessed by blinded independent central review (BICR) and a median duration of response (DoR) of 7.0 months (95% CI 4.2-9.8). The safety profile of datopotamab deruxtecan was consistent with previous reports from the TROPION-Lung05 and TROPION-Lung01 trials, with no new safety concerns identified. Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “Acquired resistance to front-line therapies and, ultimately, disease progression are unfortunate realities for most patients with advanced EGFR -mutated non-small cell lung cancer. This Priority Review, and the previously granted Breakthrough Therapy Designation, recognise the potential for datopotamab deruxtecan to provide a much-needed option to patients whose disease has become resistant to current treatments.” Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo, said: “Treating advanced EGFR -mutated non-small cell lung cancer presents a significant challenge due to the limited efficacy of available treatments once the disease has progressed following front-line therapies, including the use of an EGFR -tyrosine kinase inhibitor. If approved, datopotamab deruxtecan could become the first TROP2-directed antibody drug conjugate for lung cancer, providing a promising option for patients.” Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by AstraZeneca and Daiichi Sankyo. AstraZeneca and Daiichi Sankyo are evaluating datopotamab deruxtecan alone and in novel combinations as treatment for patients with NSCLC in seven Phase III trials including the TROPION-Lung14 and TROPION-Lung15 trials of datopotamab deruxtecan alone and with Tagrisso (osimertinib) as treatment for patients with advanced or metastatic EGFR m nonsquamous NSCLC. Advanced non-small cell lung cancer Nearly 2.5 million lung cancer cases were diagnosed globally in 2022. 2 Lung cancer is broadly split into small or non-small cell lung cancer, the latter accounting for about 80% of cases. 3 Approximately 10 to 15% of patients with NSCLC in the US and Europe, and 30 to 40% of patients in Asia have an EGFR mutation. 4,5 The majority of EGFR mutations occur in tumours of nonsquamous histology. 6 For patients with tumours that have an EGFR mutation, the established 1st-line treatment in the metastatic setting is an EGFR -TKI. 7 While EGFR -TKIs have improved outcomes in the 1st-line setting, most patients eventually experience disease progression and receive subsequent therapies, such as chemotherapy. 8-11 TROP2 is a protein broadly expressed in the majority of NSCLC tumours. 12 There is currently no TROP2-directed ADC approved for the treatment of lung cancer. 7,13 TROPION-Lung05 TROPION-Lung05 is a global, multicentre, single-arm, open-label Phase II trial evaluating the efficacy and safety of datopotamab deruxtecan in patients with locally advanced or metastatic NSCLC with actionable genomic alterations who have progressed on at least one TKI (with or without other systemic therapies) and on or after one regimen of platinum-based chemotherapy. Patients receiving up to four prior lines of treatment with tumours with one or more genomic alterations including EGFR , ALK , ROS1 , NTRK , BRAF , RET or MET were eligible for the trial. The primary endpoint of TROPION-Lung05 is ORR as assessed by BICR. Secondary efficacy endpoints include DoR, disease control rate (DCR), clinical benefit rate (CBR), progression-free survival (PFS), time to response (TTR), overall survival (OS) and safety. TROPION-Lung05 enrolled 137 patients globally in Asia, Europe and North America. For more information visit ClinicalTrials.gov. Primary results from TROPION-Lung05 were published in the Journal of Clinical Oncology in January 2025. TROPION-Lung01 TROPION-Lung01 is a global, randomised, multicentre, open-label Phase III trial evaluating the efficacy and safety of datopotamab deruxtecan versus docetaxel in adult patients with locally advanced or metastatic NSCLC with and without actionable genomic alterations who require systemic therapy following prior treatment. Patients with actionable genomic alterations were previously treated with an approved targeted therapy and platinum-based chemotherapy. Patients without known actionable genomic alterations were previously treated, concurrently or sequentially, with platinum-based chemotherapy and a PD-1 or PD-L1 inhibitor. The dual primary endpoints of TROPION-Lung01 are PFS as assessed by BICR and OS. Key secondary endpoints include investigator-assessed PFS, ORR, DoR, TTR, and DCR as assessed by both BICR and investigator, and safety. TROPION-Lung01 enrolled approximately 600 patients in Asia, Europe, North America, Oceania and South America. For more information visit ClinicalTrials.gov. Primary results from TROPION-Lung01, as presented at the ESMO 2023 Congress, showed datopotamab deruxtecan demonstrated a statistically significant improvement in PFS over docetaxel. OS results were presented at the IASLC 2024 World Conference on Lung Cancer hosted by the International Association for the Study of Lung Cancer and simultaneously published in the Journal of Clinical Oncology in September 2024. TROPION-PanTumor01 TROPION-PanTumor01 is a first-in-human, open-label, two-part, multicentre Phase I trial evaluating the safety and preliminary efficacy of datopotamab deruxtecan in patients with advanced solid tumours that have relapsed or are refractory to standard treatment or for which no standard treatment is available. The dose escalation portion of the trial enrolled patients with NSCLC to assess the safety and tolerability of datopotamab deruxtecan to determine the recommended dose for expansion (6mg/kg). The dose expansion part of TROPION-PanTumor01 enrolled several different cohorts including patients with NSCLC, triple-negative breast cancer (TNBC), hormone receptor (HR)-positive, HER2-negative breast cancer, small cell lung cancer, urothelial, gastric, pancreatic, castration resistant prostate and esophageal cancer. Safety endpoints include dose-limiting toxicities and serious adverse events. Efficacy endpoints include ORR, DoR, TTR, PFS and OS. Pharmacokinetic, biomarker and immunogenicity endpoints are also being evaluated. TROPION-PanTumor01 enrolled approximately 900 patients in Asia and North America. For more information visit ClinicalTrials.gov. Datopotamab deruxtecan (Dato-DXd) Datopotamab deruxtecan (Dato-DXd) is an investigational TROP2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, datopotamab deruxtecan is one of six DXd ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programmes in AstraZeneca’s ADC scientific platform.

Jan. 02, 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) 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 has been accepted and granted priority review by the China National Medical Products Administration (“NMPA”). ORPATHYS® is an oral, potent and highly selective MET tyrosine kinase inhibitor (“TKI”). TAGRISSO® is a third-generation, irreversible EGFR TKI. This acceptance also triggers a milestone payment from AstraZeneca. The NDA is supported by data from SACHI, a multi-center, open-label, randomized, controlled, Phase III trial which evaluated the efficacy and safety of a combination of ORPATHYS® and TAGRISSO® compared to platinum-based doublet-chemotherapy (pemetrexed plus cisplatin or carboplatin), the standard-of-care treatment option in this setting. The primary endpoint of the study was progression free survival (“PFS”) as assessed by investigators. Other endpoints include PFS assessed by an independent review committee, overall survival (OS), objective response rate (ORR), duration of response (DoR), disease control rate (DCR), time to response (TTR), and safety. 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. Results from SACHI will be submitted for presentation at an upcoming scientific conference (clinicaltrials.gov identifier NCT05015608). “This marks the first regulatory filing for the ORPATHYS® and TAGRISSO® combination. The combination has demonstrated clear evidence to address MET-driven EGFR-inhibitor resistance and offers a continued path for oral treatment,” said Dr Michael Shi, Head of R&D and Chief Medical Officer of HUTCHMED. “With our biomarker-specific approach, we are hopeful to enhance treatment continuity and quality of life for NSCLC patients navigating this challenging journey. We and our partner AstraZeneca have been exploring this combination globally, through an array of late-stage clinical trials including the TATTON, SAVANNAH, SAFFRON and ORCHARD studies, and we hope to bring this all-oral, chemotherapy-free treatment option to patients with MET-driven lung cancer in the near future.” The NMPA granted Breakthrough Therapy designation to the combination of ORPATHYS® and TAGRISSO® for this potential indication in December 2024. The NMPA granted this designation to this combination as a new treatment that could target a serious condition where clinical evidence demonstrates substantial advantages over existing therapies. 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.7 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 EGFR-mutated NSCLC.7,8 Approximately 2-3% of NSCLC patients have tumors with MET exon 14 skipping alterations, a targetable mutation in the MET gene.9 MET aberration is a major mechanism for acquired resistance to both first/second-generation EGFR TKIs as well as third-generation EGFR TKIs like osimertinib. Among patients who experience disease progression post-osimertinib treatment, approximately 15-50% present with MET aberration.10,11,12,13,14 The prevalence of MET aberration depends on the sample type, detection method and assay thresholds used.15 The combination of ORPATHYS® and TAGRISSO® has been studied extensively in patients with EGFR mutation-positive NSCLC, including the TATTON (NCT02143466) and SAVANNAH (NCT03778229) studies. The encouraging results from these studies led to the initiation of three Phase III trials with this combination: SACHI (NCT05015608) and SANOVO (NCT05009836) were initiated in China in 2021, and the global, pivotal Phase III SAFFRON (NCT05261399) study started enrollment in 2022. In comparison to other treatment options, this combination treatment is chemotherapy-free, biomarker-specific and orally administered, aiming for a balanced efficacy, safety and quality-of-life profile for lung cancer patients. SAVANNAH is a global Phase II study in patients who have progressed following osimertinib due to MET amplification or overexpression, and recruitment completed earlier in 2024. The evaluation of savolitinib in combination with osimertinib was designated as a Fast Track development program by the US Food and Drug Administration (FDA) in 2023. SAFFRON is a multi-center, randomized, controlled, open-label, global Phase III trial in patients with EGFR mutation-positive NSCLC with MET overexpression and/or amplification after disease progression on osimertinib. SACHI is a multi-center, randomized, controlled, open-label, China Phase III trial in patients with EGFR mutation-positive NSCLC with MET amplification after disease progression on any EGFR inhibitor therapy, including third-generation EGFR-TKIs such as osimertinib. SANOVO is a multi-center, randomized, controlled, blinded, China Phase III trial in treatment-naïve patients with EGFR mutation-positive NSCLC with MET-positive tumors. ORPATHYS® was granted conditional approval in China for the treatment of patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alterations who have progressed following prior systemic therapy or are unable to receive chemotherapy. ORPATHYS® is the first selective MET inhibitor approved in China. It has been included in the National Reimbursement Drug List of China (NRDL) since March 2023. A supplementary NDA is under review which, if approved, could expand this indication to include treatment-naïve adult patients in China. More than a third of the world’s lung cancer patients are in China and, among those with NSCLC globally, approximately 2-3% have tumors with MET exon 14 skipping alterations. ORPATHYS® 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 marketed in China and 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. In 2011, AstraZeneca and HUTCHMED entered a global licensing and collaboration agreement to jointly develop and commercialize ORPATHYS®. Joint development of ORPATHYS® in China is led by HUTCHMED, while AstraZeneca leads development outside of China. HUTCHMED is responsible for the marketing authorization, manufacturing and supply of ORPATHYS® in China. AstraZeneca is responsible for the commercialization of ORPATHYS® in China and worldwide. Sales of ORPATHYS® are recognized by AstraZeneca. 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. HUTCHMED (Nasdaq/AIM:​HCM; HKEX:​13) is an innovative, commercial-stage, biopharmaceutical company. It is committed to the discovery, global development and commercialization of targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. Since inception, HUTCHMED 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 in the US, Europe and Japan.
