About YL201

YL201 is a B7H3-targeting ADC developed using MediLink's proprietary Tumor Microenvironment-Activatable LINker-payload (TMALIN^®) platform. YL201 is currently under investigation in multinational clinical trials for a variety of advanced solid tumors. In China, it has advanced into two Phase III registrational trials for small cell lung cancer (SCLC) and nasopharyngeal carcinoma (NPC).
