Glycan-specific Conjugation Platform
Bispecific Antibody Platform
Subcutaneous Formulation Platform

Revolutionary Technology in Cancer Therapeutics

This platform leverages antibody Fc glycan-specific conjugation technology, utilizing an innovative one-enzyme two-step method that simplifies processes and reduces costs. It enables the development of ADCs with highly uniform DAR, demonstrating superior serum stability, enhanced bystander effects, and a broader therapeutic window, while minimizing toxicity risks. The platform has been validated for industrial-scale production and is currently expanding to develop dual-payload ADCs with customizable DAR values. Additionally, it can be integrated with other conjugation technologies, such as thiol-based conjugation and microbial transglutaminase (mTG), to generate a diverse array of next-generation ADCs.

Globally Leading Bispecific Antibody Development Platform

This platform integrates two core technologies: the Fc-based CRIB (Charge Repulsion Induced Bispecific) heterodimer platform and the single-domain antibody assembly platform. The CRIB technology overcomes critical CMC (Chemistry, Manufacturing, and Control) challenges in asymmetric bispecific antibody production, enabling stable manufacturing of high-purity bispecific antibodies. The single-domain antibody assembly technology allows flexible construction of quadrivalent symmetric bispecific antibodies, which enhance tumor targeting precision through dual-target synergy while minimizing off-target risks. The platform’s advantages have been validated across multiple product candidates.

Innovation in Drug Administration Technology

Subcutaneous high concentration formulation platform has successfully overcome technical barriers in developing high-concentration (≥150 mg/mL) liquid formulations for antibody drugs, enabling long-term stable storage (24-month stability under 2-8℃conditions). It has completed the commercial formulation development for products such as KN035 (PD-L1 single-domain antibody), with patient compliance surveys showing a satisfaction rate of 92%. For ADCs, the platform offers subcutaneous formulations that reduce infusion reactions (incidence lowered to <5%) and hematologic toxicity associated with intravenous administration.
