About Alphamab Oncology

http://www.alphamabonc.com

Alphamab Oncology is an innovative biopharmaceutical company specializing in the research, development, and commercialization of differentiated anti-tumor biotherapeutics. The company is dedicated to addressing unmet clinical needs in oncology by developing effective, safe, and globally competitive cancer therapies. A core unique selling point is its proprietary technology platform for Antibody-Drug Conjugates (ADCs). This platform utilizes site-specific conjugation via Fc glycan, employing a one-enzyme, two-step process to produce ADCs with a highly uniform Drug-to-Antibody Ratio (DAR). This method results in superior serum stability and enhanced bystander killing effect, aiming to widen the therapeutic window and minimize toxic side effects. Key pipeline assets include KN035 and the biparatopic HER2-targeting ADC, JSKN003, which has received Breakthrough Therapy Designation from the FDA.
