CHENGDU, China, June 6, 2025 /PRNewswire/ — Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. (“Kelun-Biotech”, 6990.HK) today announced that results from its registrational study (OptiTROP-Lung03) evaluating sacituzumab tirumotecan (sac-TMT) versus docetaxel in patients with previously treated advanced EGFR-mutant non-small cell lung cancer (NSCLC) have been published in The British Medical Journal (impact factor: 93.6). These data were also presented as an oral presentation in the Lung Cancer—Non–Small Cell Metastatic session (Abstract #8507) at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. Based on the encouraging data from this study, sac-TMT was approved for marketing by the National Medical Products Administration (NMPA) for the treatment of adult patients with epidermal growth factor receptor (EGFR) mutant-positive locally advanced or metastatic non-squamous NSCLC following progression on EGFR-tyrosine kinase inhibitor (TKI) therapy and platinum-based chemotherapy in March 2025. This marks the first global approval of a TROP2 ADC for a lung cancer indication.
