kn046 and kn026 combination therapy

kn046 and kn026 are two innovative bispecific antibodies independently developed by alphamab oncology. both products have shown good safety, tolerability and preliminary efficacy in clinical trials. the clinical trial under application aims to study kn046 in combination with kn026 for the treatment of her2-positive or expressing solid tumors, including but not limited to her2-positive or expressing breast cancer, gastric cancer/gastroesophageal junction cancer, esophageal cancer, colorectal cancer, pancreatic cancer, bile duct cancer, ovarian cancer, urothelial cancer and lung cancer.


kn046 and ningetinib combination therapy

alphamab oncology and sunshine lake pharma co., ltd. reached a cooperation agreement on kn046 and ningetinib toluenesulfonate for the treatment of hepatocellular carcinoma (hcc) in january 2019. this ind application aims to study the safety, tolerability and preliminary efficacy of kn046 in combination with ningetinib toluenesulfonate for hematology malignancies and solid tumors including advanced hepatocellular carcinoma.


kn026 injection

previously, the ind of lyophilized dosage form of kn026 was approved by china nmpa and the us food and drug administration (fda) in 2018, and is currently undergoing phase i clinical trials in the united states and phase ii clinical trials in china for a variety of indications. the recent ind application for kn026 injection is filed for liquid dosage form developed by the company. it targets first-line treatment of recurrent or metastatic her2-positive or expressing breast cancer.

dr. ting xu, founder, chairman and ceo of alphamab oncology, commented : "kn046 and kn026 are the next-generation bispecific drugs for cancer treatment with great potential, and the anti-tumor effects of the two products have been preliminarily demonstrated in a variety of clinical trials. these ind applications mark that alphamab oncology is entering the stage of clinical study of combination therapy. the company will further study the clinical potential of the product pipeline through combination therapies including combination of kn046 and kn026, striving to provide world-class biological therapy for cancer patients and make contributions to 'healthy china 2030'".

about kn046

kn046 is the world's first recombinant humanized pd-l1/ctla-4 bispecific antibody independently developed by alphamab. its innovative designs include: a bispecific antibody fused with pd-l1 antibody; engineered to target the tumor microenvironment with high pd-l1 expression; a proprietary ctla-4 domain antibody with a significantly improved safety profile; treg clearing function. the preclinical and clinical study results of kn046 have shown promising efficacy and reduced toxicity to human peripheral system, with the potential to become the backbone of next generation immuno-oncology therapy in the future.

previously, kn046's phase i clinical trials in australia and china have shown an preliminary profile of good safety and promising efficacy, and several phase ii clinical trials are ongoing in china for nsclc, tnbc and escc.

about kn026

kn026 is an anti-her2 bispecific antibody developed 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. in pre-clinical studies, kn026 has demonstrated potentially equivalent or superior efficacy compared with trastuzumab and pertuzumab alone or in combination, 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 phase i trials in china have shown good safety and preliminary efficacy.

kn026 received ind approval from the national medical products administration of china and u.s. food and drug administration in 2018. currently, it is under phase i clinical trial in the united states and phase ii clinical trial in china targeting at many indications.
