About KN046
KN046 is PD-L1/CTLA-4 bispecific antibody independently developed by Jiangsu Alphamab. Its innovative designs include: a novel mechanism - CTLA-4 fused with PD-L1 single domain antibody; engineered to target the tumor microenvironment with high PD-L1 expression, and Treg (suppress tumor immunity) clearing function.
There are about 20 clinical trials of KN046 in different stages covering more than 10 types of tumors including NSCLC, thymic cancer, pancreatic cancer, HCC, ESCC and TNBC in Australia, the US and China. The results of these clinical trials have shown an advantage in survival for patients. Alphamab Oncology has received FDA clearance to enter phase II trial of KN046 based on the clinical results in China and Australia. Moreover, KN046 has obtained the U.S. FDA's orphan drug designation for thymic epithelial tumor in September 2020. Four pivotal clinical trials are currently being conducted.
About KN026
KN026 is an anti-HER2 bispecific antibody invented by Alphamab Oncology using the proprietary Fc-based heterodimer bispecific platform technology called CRIB (Charge Repulsion Induced Bispecific). KN026 can bind two non-overlapping epitopes of HER2 simultaneously, leading to a dual HER2 signal blockade. KN026 has demonstrated potentially equivalent efficacy compared with Trastuzumab and Pertuzumab in combination, and was superior to either single agent, such as increased binding affinity, as well as better tumor inhibition in HER2-positive tumor cell lines. Additionally, KN026 has also shown inhibitory effect on tumor cells with medium or low HER2 expression or Trastuzumab-resistant cell lines.
KN026 received IND approval from the National Medical Products Administration (NMPA) of China and U.S. Food and Drug Administration (FDA) in 2018. Currently, it is in multiple phase I/II clinical trials in China and phase I clinical trial in the United States. The results of Phase I clinical trials show KN026 has good safety, tolerance and potentially superior anti-tumor activity in HER2-positive breast cancer patients who progressed after multiple lines of anti-HER2 treatment.
