Alphamab Oncology (HKG:9966) said JSKN003 received approval from the Center for Drug Evaluation of China's National Medical Products Administration to initiate a phase III clinical study, according to Friday filing with the Hong Kong bourse.
JSKN003 is a HER2-targeting ADC (antibody-drug conjugate) that combines a topoisomerase I inhibitor with KN026 (a humanized anti-HER2 bispecific antibody) used to treat tumors. The drug linker is attached specifically to the antibody's N-glycosylation site using glycoside-specific conjugation, the filing added.
