kn026 is an anti-her2 fc-based heterodimer bispecific antibody which can bind two non-overlapping epitopes of her2 simultaneously, leading to a dual her2 signal blockade. in pre-clinical studies, kn026 has demonstrated equivalent or superior efficacy compared with trastuzumab and pertuzumab alone or in combination, such as increased binding affinity, as well as better efficacy in tumor inhibition in her2-positive tumor cell lines. additionally, kn026 also shown inhibitory effect on tumor cells with low her2 expression or trastuzumab-resistant cell lines.
at present, the phase i dose-escalating clinical trial of kn026 conducted in china is approaching completion, and the preliminary results have shown good safety and preliminary efficacy. additionally, kn026 is entering clinical trials in the united states.
the phase ii clinical trial aims to evaluate the safety, efficacy and tolerability of kn026 in patients with advanced gastric or gastroesophageal junction carcinomas with her2 overexpression and medium or low expression. this trial is led by professor jianming xu from the fifth medical center of pla general hospital as the leading principle investigator. eight clinical sites participate in the study, including the oncology hospital affiliated to harbin medical university, the first affiliated hospital of zhengzhou university, zhejiang oncology hospital, the first affiliated hospital of medical school of zhejiang university, the first affiliated hospital of nanchang university and the first people’s hospital of changzhou.
