SINO BIOPHARM (01177) rose more than 4%, reaching a 2.87% gain at press time to trade at HK$7.16, with a turnover of HK$174 million. The catalyst behind the rally was the online publication of Phase II clinical trial results for TQB2102, a HER2-targeted bispecific antibody-drug conjugate (ADC), in the prestigious Journal of Clinical Oncology (IF 43.4) on November 25. TQB2102, developed by SINO BIOPHARM's subsidiary Chia Tai Tianqing, is an ADC targeting two non-overlapping HER2 epitopes (ECD2 and ECD4). Led by Professor Shao Zhimin's team at Fudan University Shanghai Cancer Center, the study marks the first to demonstrate the efficacy and safety of this dual-epitope HER2 ADC in neoadjuvant breast cancer treatment. A Phase III registration trial is currently underway.
