TOKYO, Japan & BASKING RIDGE, NJ, USA I October 30, 2024 I The first patients have been dosed in three global, randomized phase 3 trials evaluating the efficacy and safety of datopotamab deruxtecan (Dato-DXd)-based combinations in patients with locally advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC). Datopotamab deruxtecan is a specifically engineered TROP2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN). TROPION-Lung10 is evaluating datopotamab deruxtecan plus rilvegostomig, AstraZeneca’s PD-1/TIGIT bispecific antibody, or rilvegostomig alone versus pembrolizumab in patients with previously untreated locally advanced or metastatic nonsquamous NSCLC with high PD-L1 expression (tumor cells [TC] ≥ 50%) and without actionable genomic alterations. TROPION-Lung14 is evaluating datopotamab deruxtecan plus osimertinib, AstraZeneca’s EGFR tyrosine kinase inhibitor (TKI), versus osimertinib alone in patients with previously untreated locally advanced or metastatic EGFR mutated nonsquamous NSCLC. TROPION-Lung15 is evaluating datopotamab deruxtecan with or without osimertinib versus platinum-based doublet chemotherapy in patients with locally advanced or metastatic nonsquamous EGFR mutated NSCLC whose disease progressed on prior treatment with osimertinib. “These three trials in either high PD-L1 expressing or EGFR mutated nonsquamous non-small cell lung cancer are critical to helping us understand the potential role of datopotamab deruxtecan in treating patients across different lines and types of lung cancer,” said Mark Rutstein, MD, Global Head, Oncology Clinical Development, Daiichi Sankyo. “Our growing TROPION clinical program, which now consists of seven phase 3 trials demonstrates our commitment to understanding the full potential of datopotamab deruxtecan in lung cancer.” “Clinical research suggests that combining an antibody drug conjugate with a targeted treatment or a bispecific immunotherapy may drive stronger and more durable tumor responses in patients with a variety of cancers including lung cancer,” said Cristian Massacesi, MD, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca. “The initiation of these additional three phase 3 trials of datopotamab deruxtecan in combination with our agents, osimertinib and rilvegostomig illustrates our commitment to exploring potential synergies within our oncology pipeline as well as the full potential and combinability of this TROP2 directed antibody drug conjugate across multiple segments and settings of non-small cell lung cancer.” About TROPION-Lung10 TROPION-Lung10 is a global, multicenter, open-label, three-arm phase 3 trial where patients will be randomized in a 2:1:2 ratio to evaluate the efficacy and safety of datopotamab deruxtecan (6.0 mg/kg) in combination with rilvegostomig (750 mg) or rilvegostomig (750 mg) monotherapy versus pembrolizumab (200 mg) monotherapy in adult patients with previously untreated locally advanced or metastatic nonsquamous NSCLC with high PD-L1 expression (TC ≥ 50%) and without actionable genomic alterations. The dual primary endpoints of TROPION-Lung10 are progression-free survival (PFS) as assessed by blinded independent central review (BICR) and overall survival (OS) in patients with TROP2 positive tumors receiving datopotamab deruxtecan in combination with rilvegostomig versus the pembrolizumab arm. A pre-specified retrospective analysis from tumor biopsies collected pretreatment will be conducted following validation of a potential TROP2 biomarker determined by quantitative continuous scoring, a computational pathology approach. Key secondary endpoints for all arms of the trial include PFS as assessed by BICR and investigator and OS in the intention-to-treat (ITT) population, objective response rate (ORR) as assessed by BICR and duration of response (DoR) as assessed by BICR and investigator in both TROP2 biomarker positive and the ITT populations. The safety and tolerability of datopotamab deruxtecan in combination with rilvegostomig and rilvegostomig monotherapy as compared with pembrolizumab also will be assessed. TROPION-Lung10 will enroll approximately 675 patients in Asia, Europe, North America, Oceania and South America. For more information visit ClinicalTrials.gov . The TIGIT component of rilvegostomig is derived from the clinical-stage anti-TIGIT antibody, COM902, developed by Compugen Ltd. (Nasdaq/TASE: CGEN). About TROPION-Lung14 TROPION-Lung14 is a global, randomized, multicenter, open-label phase 3 trial evaluating the efficacy and safety of datopotamab deruxtecan (6.0 mg/kg) in combination with osimertinib (80 mg) versus osimertinib (80 mg) monotherapy in adult patients with previously untreated locally advanced or metastatic nonsquamous NSCLC with an EGFR mutation (Exon 19 deletion and/or L858R). The randomized period of the trial is preceded by a single-arm safety run-in period which will enroll approximately 20 patients to evaluate the combination therapy. The primary endpoint of TROPION-Lung14 is PFS as assessed by BICR. Key secondary endpoints include central nervous system (CNS) PFS as assessed by CNS BICR, PFS as assessed by investigator, ORR as assessed by BICR and investigator, OS and safety. TROPION-Lung14 will enroll approximately 580 patients in Asia, Europe, North America, Oceania and South America. For more information visit ClinicalTrials.gov . About TROPION-Lung15 TROPION-Lung15 is a global, multicenter, open-label, three-arm phase 3 trial where patients will be randomized in a 1:1:1 ratio to evaluate the efficacy and safety of datopotamab deruxtecan (6.0 mg/kg) as monotherapy or in combination with osimertinib (80 mg) versus platinum-based doublet chemotherapy (pemetrexed in combination with carboplatin or cisplatin followed by pemetrexed maintenance) in adult patients with locally advanced or metastatic nonsquamous NSCLC with at least one EGFR mutation (G719X, Ex19del, S768I, L858R, and/or L861Q) and with disease progression following prior treatment with osimertinib. The dual primary PFS endpoints of TROPION-Lung15 are PFS as assessed by BICR for datopotamab deruxtecan monotherapy versus chemotherapy and datopotamab deruxtecan in combination with osimertinib versus chemotherapy. Key secondary endpoints include investigator-assessed CNS PFS as assessed by CNS BICR, ORR and DoR as assessed by BICR, OS and safety. TROPION-Lung15 will enroll approximately 630 patients in Asia, Europe, North America, Oceania and South America. For more information visit ClinicalTrials.gov . About Advanced Non-Small Cell Lung Cancer Nearly 2.5 million lung cancer cases were diagnosed globally in 2022. 1 NSCLC is the most common type of lung cancer, accounting for about 85% of cases. 2 Approximately 75% and 25% of NSCLC tumors are of nonsquamous or squamous histology, respectively, with EGFR mutations occurring in 14% to 38% of all NSCLC tumors worldwide. 3,4 A majority of EGFR mutations occur in tumors with nonsquamous histology. 5 For patients with tumors that do not express a known actionable genomic alteration (e.g., EGFR, ALK, ROS1, NTRK, BRAF, RET or MET), the current first-line standard of care in the metastatic setting is an immune checkpoint inhibitor and/or platinum-based chemotherapy based on PD-L1 expression. 6,7,8 For certain patients with tumors that have EGFR mutations, the established first-line treatment in the metastatic setting is an EGFR TKI. 9 While these treatment strategies have improved outcomes in the first-line metastatic setting, most patients eventually experience disease progression. 10,11,12 TROP2 is a protein broadly expressed in the majority of NSCLC tumors. 13 There is currently no TROP2 directed ADC approved for the treatment of lung cancer. 8,9 About 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 programs in AstraZeneca’s ADC scientific platform. Datopotamab deruxtecan is comprised of a humanized anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. A comprehensive global clinical development program is underway with more than 20 trials evaluating the efficacy and safety of datopotamab deruxtecan across multiple cancers, including NSCLC, triple negative breast cancer and HR positive, HER2 negative breast cancer. The program includes seven phase 3 trials in lung cancer and five phase 3 trials in breast cancer evaluating datopotamab deruxtecan as a monotherapy and in combination with other anticancer treatments in various settings. About the Daiichi Sankyo and AstraZeneca Collaboration Daiichi Sankyo and AstraZeneca entered into a global collaboration to jointly develop and commercialize ENHERTU in March 2019 and datopotamab deruxtecan (Dato-DXd) in July 2020 , except in Japan where Daiichi Sankyo maintains exclusive rights for each ADC. Daiichi Sankyo is responsible for the manufacturing and supply of ENHERTU and datopotamab deruxtecan. About the ADC Portfolio of Daiichi Sankyo The Daiichi Sankyo ADC portfolio consists of seven ADCs in clinical development crafted from two distinct ADC technology platforms discovered in-house by Daiichi Sankyo. The ADC platform furthest in clinical development is Daiichi Sankyo’s DXd ADC Technology where each ADC consists of a monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. The DXd ADC portfolio currently consists of ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan (Dato-DXd), a TROP2 directed ADC, which are being jointly developed and commercialized globally with AstraZeneca. Patritumab deruxtecan (HER3-DXd), a HER3 directed ADC, ifinatamab deruxtecan (I-DXd), a B7-H3 directed ADC, and raludotatug deruxtecan (R-DXd), a CDH6 directed ADC, are being jointly developed and commercialized globally with Merck. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo. The second Daiichi Sankyo ADC platform consists of a monoclonal antibody attached to a modified pyrrolobenzodiazepine (PBD) payload. DS-9606, a CLDN6 directed PBD ADC, is the first of several planned ADCs in clinical development utilizing this platform. Datopotamab deruxtecan, ifinatamab deruxtecan, patritumab deruxtecan, raludotatug deruxtecan, DS-3939 and DS-9606 are investigational medicines that have not been approved for any indication in any country.

This approval marks the second international marketing authorization for sugemalimab outside of China, following its recent approval by the European Commission. The approval is based on results from the Phase 3 GEMSTONE-302 clinical trial, which demonstrated that sugemalimab in combination with chemotherapy significantly prolonged progression-free survival (PFS) and overall survival (OS) in treatment-naive patients with metastatic NSCLC. Long-term survival data from the GEMSTONE-302 study were presented at the 2024 European Society for Medical Oncology (ESMO) Annual Meeting. CStone is actively communicating with regulatory authorities, including the European Medicines Agency (EMA) for marketing authorization applications for additional indications of sugemalimab. CStone has entered into a strategic commercialization partnership with Ewopharma for sugemalimab in Central & Eastern Europe and Switzerland, with further collaborations expected soon in regions including Western Europe, Latin America, the Middle East, and Southeast Asia. SUZHOU, China, Oct. 31, 2024 /PRNewswire/ -- CStone Pharmaceuticals (HKEX: 2616), an innovation-driven biopharmaceutical company focused on the research and development of anti-cancer therapies, today announced that the UK Medicines and Healthcare products Regulatory Agency (MHRA) has approved sugemalimab in combination with platinum-based chemotherapy as a first-line treatment for adult patients with metastatic non-small cell lung cancer (NSCLC) without EGFR-sensitive mutations or ALK, ROS1, RET genomic alterations. This marks the second overseas approval for sugemalimab following its recent authorization by the European Commission. Dr. Jason Yang, CEO, President of R&D and Executive Director of the Board at CStone, said, "This approval is a significant milestone in our global expansion strategy. Sugemalimab is the first domestic anti-PD-L1 antibody to receive approval outside of China and has already entered the world's second-largest pharmaceutical market, the EU. Now, with the UK approval, sugemalimab continued to expand its presence in the European market. The long-term survival data, recently presented at this year's ESMO Congress, further confirmed sugemalimab's value in the frontline treatment landscape for metastatic NSCLC." Dr. Yang added, "We are actively pursuing additional partnerships across Western Europe, Latin America, the Middle East, Southeast Asia, and Canada, and expect to finalize some of these agreements shortly. Meanwhile, we are communicating with the European Medicines Agency (EMA) and other agencies for additional regulatory applications for other sugemalimab indications, including Stage III NSCLC, first-line gastric cancer, and first-line esophageal squamous cell carcinoma, aiming to bring innovative treatment options to more patients globally." The MHRA's approval is primarily based on the data from GEMSTONE-302, a multicenter, randomized, double-blind phase 3 trial. The study demonstrated that sugemalimab in combination with chemotherapy significantly prolonged progression-free survival (PFS) and overall survival (OS) compared to placebo combined with chemotherapy in treatment-naïve patients with metastatic NSCLC. Study results have been published in The Lancet Oncology and Nature Cancer, and have been presented at multiple international academic conferences in both oral and poster sessions.

In addition, Biocartis will host a free corporate workshop. Six Idylla™ abstracts from renowned institutions will be presented at this year's AMP conference, showcasing the strong collaborations Biocartis has built with leading research and academic partners. 1. Performance Assessment and Clinical Validation of the Idylla™ IDH1-2 Mutation Assay Kit in Rapid Detection of IDH Mutations in Acute Myeloid Leukemia Ashutosh Vashisht, Ashis K Mondal, Lora Walczak, Vishakha Vashisht, Shubha Sharma, Pankaj Ahluwalia, Jana Woodall, Harmanpreet Singh, Ravindra Kolhe - Department of Pathology, Medical College of Georgia, Augusta University, GA, USA. By using 36 samples from 18 unique AML cases, the authors were able to demonstrate perfect concordance (100%) of the Idylla™ IDH1-2 Mutation Assay Kit with NGS. Directly using bone marrow aspirate in the Cartridge significantly reduced turnaround time, making this technique an ideal solution for developing assays for AML diagnosis, prognosis, and treatment evaluation. 2. The Idylla™ Platform Enables Rapid and Accurate EGFR Mutation Assessment in NSCLC with Minimal Sample InputKatherine Drews-Elger, Rodrigo Santoscoy-Valencia, Catherine Garcia-Serje, Silvia Gonzalez-Leiva, Mayra Rodriguez, Orlando Bracho-Rincon, and Roberto Ruiz-Cordero - Department of Pathology and Laboratory Medicine, University of Miami, Miami, FL - Jackson Memorial Hospital, Miami, FL - Clinical OncoMolecular Lab, Department of Pathology and Laboratory Medicine, University of Miami, Miami, FL. This new prospective study demonstrated how the Idylla™ EGFR Mutation Assay offered rapid and accurate detection of EGFR mutations in non-small cell lung cancer (NSCLC), with 95% concordance with NGS. The Assay successfully identified mutations in cases where NGS could not be performed (10% of the cohort) and reduced turnaround time from 12.1 to 1.7 days. With minimal sample requirements and hands-on time, Idylla™ provided a faster option for obtaining EGFR mutation status in NSCLC. 3. Re-verification and Report Ruling Revision of NTRK Fusion Results of Idylla™ GeneFusion Assay after Manufacturer Algorithm UpdatePatricia Caffes, Gang Zheng M.D. Ph.D., Ying-Chun Lo M.D. Ph.D. - Division of Laboratory Genetics and Genomics, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN - Division of Anatomic Pathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN. This recent re-verification study of the Idylla™ GeneFusion Assay demonstrated improved sensitivity for detecting NTRK2 fusions, due to a software update. Although sensitivity for NTRK3 decreased slightly, updates to the laboratory’s standard operating procedure have enhanced accuracy by requiring confirmation testing for certain equivocal results. The study showed no changes to the detection of ALK, ROS1, RET, and MET fusions, maintaining 100% sensitivity and specificity. 4. Rapid Determination of IDH1 and IDH2 Mutation Status in AML and Glioma Using Microfluidic Detection SystemCatalina Esguerra, Anthony Magliocco - Protean BioDiagnostics This study showed 97% accuracy, 100% sensitivity and 95% specificity for detecting IDH1 and IDH2 mutations in glioma and AML samples with the Idylla™ IDH1-2 Mutation Assay Kit. The Assay delivered rapid results within 95 minutes, with only one discordant case under investigation, potentially due to a higher sensitivity than the reference test. The Idylla™ System was praised for its ease of use and reliability, making it a valuable tool for determining IDH mutation status in various malignancies. 5. The Idylla™ POLE Mutation Assay, a New Tool for Direct Mutation Detection from FFPE TissueSofie Metsu - Biocartis Based on a literature review, the diagnostic sensitivity of the (under development) Idylla™ POLE Mutation Assay for detecting POLE mutations with evidence to support clinical utility, was 98% in endometrial cancer and 90% colorectal cancer. The new assay is currently undergoing evaluation at multiple selected sites across Europe and the US, using clinical endometrial carcinoma FFPE specimens. The conclusive results will be shared at the AMP conference. 6. Same-Day Molecular Testing Results from Cytology Specimens: The Next Frontier of the Rapid On-site Evaluation?Dr. Gloria Sura - Cytology, MDACC This MDACC study demonstrated the feasibility of Idylla™ for rapid and accurate molecular testing of NSCLC and thyroid cancer biomarkers from cytology samples. Results were available in 2-3 hours, with high accuracy across KRAS, EGFR, BRAF and GeneFusion Assays, showing concordance rates of 94-100%. The Biocartis corporate workshop will take place on November 20th, 2024 at 3 PM PST and is focused on optimizing Fine Needle Aspiration (FNA) workflows using the Idylla™ Platform. Gloria Sura, MD (MD Anderson Cancer Center) will present a comprehensive feasibility and performance study showcasing the rapid assessment of EGFR, KRAS, BRAF and GeneFusion in cytopathology. Dr. Sura will highlight the integration of cytology and small biopsy specimens, particularly in lung and thyroid cancers, within a large cancer center. W.
