Core Competence
Fc-Based Designer Biologics, FBDB™

The core technology of HanchorBio is the FBDB™ (Fc-Based Designer Biologics) platform, which focuses on the development of next-generation immuno-oncology fusion protein therapeutics. This platform utilizes the antibody Fc region as a backbone, onto which various engineered anti-cancer molecules are constructed through protein engineering. Combined with AI-assisted drug design capabilities, this technology is dedicated to overcoming key challenges in tumor immunotherapy.

World-Leading Innovative Tri-Functional Biologics Technology

Over 160 antibody drugs have already been approved by global regulatory agencies, including 17 bispecific antibodies.
Globally, no tri-functional antibodies or fusion proteins have been approved to date.
Among the more than 2,400 antibody or fusion protein candidates currently in clinical development, tri-functional biologics remain rare and valuable, accounting for only 1.6% of all projects worldwide.
