Lepu Biopharma Co. Ltd. has announced the results of a pivotal clinical trial for their drug candidate, MRG003, which were presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The study focused on the treatment of recurrent or metastatic nasopharyngeal cancer (R/M NPC) using MRG003, a novel EGFR-targeted antibody-drug conjugate. In a randomized-controlled, multicenter, open-label study, MRG003 demonstrated statistically and clinically significant benefits in heavily pretreated patients compared to chemotherapy. The trial enrolled 173 patients, with MRG003 showing a higher objective response rate of 30.2% compared to 11.5% for chemotherapy. The study highlights a potential shift in treatment paradigms for R/M NPC. However, the company cautions that there is no guarantee of MRG003's successful development and market launch.
