J INTS BIO to Present Global Clinical Results from JIN-A02, a Fourth-Generation EGFR-TKI, at ASCO 2025
Significant anti-tumor responses and reduction of brain metastases observed SEOUL, South Korea , June 2, 2025 /PRNewswire/ -- J INTS BIO, a company specializing in the development of therapeutics for cancer and rare diseases, officially announced interim results from the global Phase 1/2 clinical trial of JIN-A02, its fourth-generation EGFR-TKI drug candidate, at the American Society of Clinical Oncology 2025 (ASCO 2025), the world's largest oncology conference, held in Chicago, USA. JIN-A02 is an oral, fourth-generation EGFR-TKI designed to overcome resistance mutations (such as C797S) that develop after treatment failure with third-generation EGFR-TKIs, which are currently the first-line therapy for EGFR-mutant Non-small cell lung cancer (NSCLC). It is currently undergoing clinical trials in South Korea, the United States, Thailand, and other countries. Key efficacy and safety results from Part A (dose escalation) of the multi-center clinical trial (NCT05394831) were presented. 'Confirmed' clinical response observed in patients with disease progression after 3 rd Generation EGFR TKI and chemotherapy One of the key findings of the ASCO presentation was that tumor responses were sustained in specific dose cohorts, with confirmed partial responses (PRs) verified by independent evaluation. Confirmed PRs were observed in 50mg,100mg and 300mg QD dose groups, providing clinical evidence of anti-tumor activity. In the 50 mg dose group, patients achieved a 77.3% reduction in tumor size, maintaining a PR over six consecutive treatment cycles (from cycle 3 to cycle 13). In the 300 mg dose group, a confirmed PR was observed with a 39.7% tumor size reduction, including a significant reduction in brain metastatic lesions. In the 100 mg dose group, a PR was also reported with a 35.3% reduction in tumor size, and brain metastatic lesions remained stable, further supporting the potential of JIN-A02 in treating brain metastases. Safety confirmed up to 300 mg, with therapeutic signals in brain metastases No dose-limiting toxicities (DLTs) or serious adverse events were observed with JIN-A02 at doses up to 300mg, which is six times the dose level when PR was first observed, demonstrating a favorable safety profile even at higher dose levels. The majority of adverse events reported at 300mg were mild (Grade 1-2) and included for the first time, Grade 1 skin rash, diarrhea, and skin desquamation in 3 out of 5 subjects – events commonly associated with EGFR inhibitors and generally considered clinically manageable. Importantly, there were no reports of systemic toxicities such as cardiovascular events or hepatotoxicity, supporting the drug's excellent safety profile. This safety and tolerability have translated into extended treatment durations in real-world settings, with a patient still on JIN-A02 after one year and seven months. In addition, the trial demonstrated notable responses in brain metastases first noted at 100mg, suggesting that JIN-A02 achieves therapeutically relevant concentrations in brain tissue. JIN-A02 gains national spotlight as government grants accelerate development In addition to the ASCO announcement, J INTS BIO continues to achieve noteworthy results in Korea. Recently, it was selected for the '2025 Baby Unicorn Fostering Project' by the Ministry of SMEs and Startups, officially recognizing both our scientific technology and commercialization potential. The 'Baby Unicorn Fostering Project' is a government project that focuses on developing promising startups with innovative technologies and growth potential in the global market as 'potential unicorns'. Companies selected for this project will receive full government support in recognition of their technological prowess and growth potential. With these accolades, JIN-A02 will receive dual funding for its Phase 2 trial and global expansion over the next two years, which is expected to be a decisive point to significantly accelerate the pace of clinical and commercialization in parallel with private investment. It is also significant as a case of securing confidence in the 3 arena of technology, marketability, and global scalability, as the recognition came from different government departments. Based on these achievements, we plan to initiate the Phase 2 clinical trial of JIN-A02 in before the end of this year, in discussions with the US FDA. "The ASCO presentation of JIN-A02's ability to induce anti-cancer responses and its ability to respond to central nervous system metastatic lesions is of great significance," said Dr. Anna Jo, CEO. "The government's continued support is a recognition of our technical capabilities and potential for growth. We will take advantage of this opportunity to accelerate global clinical expansion, technology transfer, and indication expansion to realize our goal of early commercialization"

Kelun-Biotech's TROP2 ADC Sacituzumab Tirumotecan (sac-TMT) Approved for Marketing in Second Indication by NMPA for EGFRm NSCLC
CHENGDU, China, March 10, 2025 /PRNewswire/ -- Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. (the 'Company') announced that the Company's trophoblast cell-surface antigen 2 (TROP2)-directed antibody-drug conjugate (ADC) sacituzumab tirumotecan (sac-TMT, formerly SKB264/MK-2870) was approved for marketing by the National Medical Products Administration (NMPA) for the second indication which is for the treatment of adult patients with epidermal growth factor receptor (EGFR) mutant-positive locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) following progression on EGFR-tyrosine kinase inhibitor (TKI) therapy and platinum-based chemotherapy. This is the first TROP2 ADC drug approved for marketing in lung cancer globally. Compared with current standard of care, sac-TMT significantly extents the overall survival benefits of these patients. The approval is based on a multi-center, randomized, controlled, pivotal study (OptiTROP-Lung03) that evaluates the efficacy and safety profile of sac-TMT monotherapy 5mg/kg every other week (Q2W) as an intravenous injection versus docetaxel for the treatment of patients with locally advanced or metastatic EGFR-mutant NSCLC who have failed after treatment with an EGFR-TKI and platinum-based chemotherapy (used sequentially or in combination). As demonstrated in a pre-specified interim analysis, sac-TMT monotherapy demonstrated a statistically significant and clinically meaningful improvement in objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) compared with docetaxel. Sac-TMT is also the first ADC drug to demonstrate a statistically and clinically significant improvement in overall survival benefit versus standard of care in patients with EGFR-mutant NSCLC after failure of EGFR-TKI and platinum-based chemotherapy. Previously, the NMPA has approved the marketing of sac-TMT in China for adult patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC) who have received at least two prior systemic therapies (at least one of them for advanced or metastatic setting) and accepted a supplemental new drug application (sNDA) seeking the approval of sac-TMT monotherapy for patients with EGFR-mutant NSCLC who have failed after EGFR-TKI therapy. Currently, sac-TMT is fully deployed in the NSCLC field, and Merck Sharp & Dohme and the company are conducting a total of 10 registrational Phase Ⅲ clinical studies in NSCLC globally and in China, with the threads covering from the late backline to early postoperative adjuvant, including monotherapy and combination studies. Among them, a registrational Phase Ⅲ clinical study has been conducted in China in combination with osimertinib for the first-line treatment of locally advanced or metastatic NSCLC with EGFR mutations (OptiTROP-Lung07). Dr. Michael Ge, CEO of Kelun-Biotech said, 'We are very pleased that the second indication of the Company's TROP2 ADC sacituzumab tirumotecan has been approved for marketing, which is exciting progress for us in the field of lung cancer. The successful approval of this new indication will help to address an unmet treatment need for patients with later-stage EGFRm NSCLC in China. Kelun-Biotech has always been committed to promoting innovation and leadership, and we look forward to continuing our research in the field of ADCs in partnership with MSD.' About NSCLC Lung cancer, the second most common cancer in the world, includes two main types of cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most common pathological type, accounting for about 80 to 85% of all lung cancers. The molecular typing of NSCLC patients in China is different from that of Western populations, and EGFR mutation is a common variant gene type, accounting for about 40 to 50% of lung adenocarcinoma patients in China. According to the 2024 Chinese Journal of Cancer Research (CSCO) guidelines, EGFR-TKIs are the preferred treatment for stage IV EGFR-mutant NSCLC.1 Platinum-containing chemotherapy is the main first-line chemotherapy regimen after resistance to EGFR-TKIs; and existing treatment regimens are ineffective in those who have failed EGFR-TKIs and platinum-containing chemotherapy. New drugs are urgently needed to improve patient survival. About sac-TMT (佳泰莱®) Sac-TMT, a core product of the Company, is a novel human TROP2 ADC in which the Company has proprietary intellectual property rights, targeting advanced solid tumors such as NSCLC, breast cancer (BC), gastric cancer (GC), gynecological tumors, among others. Sac-TMT is developed with a novel linker to conjugate the payload, a belotecan-derivative topoisomerase I inhibitor with a drug-to-antibody-ratio (DAR) of 7.4. Sac-TMT specifically recognizes TROP2 on the surface of tumor cells by recombinant anti-TROP2 humanized monoclonal antibodies, which is then endocytosed by tumor cells and releases KL610023 intracellularly. KL610023, as a topoisomerase I inhibitor, induces DNA damage to tumor cells, which in turn leads to cell-cycle arrest and apoptosis. In addition, it also releases KL610023 in the tumor microenvironment. Given that KL610023 is membrane permeable, it can enable a bystander effect, or in other words kill adjacent tumor cells. In May 2022, the Company licensed the exclusive rights to MSD (the tradename of Merck & Co., Inc., Rahway, NJ, USA) to develop, use, manufacture and commercialize sac-TMT in all territories outside of Greater China (includes Mainland China, Hong Kong, Macau, and Taiwan).
