STAR-Lite Bispecific Antibody Platform
STAR-Lite platform has successfully deployed and developed Multiple bispecific antibody drug candidates
● Common light chain, no mismatch between light and heavy chains
● Not reduce the diversity of light chains (compared to common light chain animal platforms)
● Not rely on expensive mouse platforms such as Veloclmmune、OmniFlic、RenLite® 、 MeMo®
● Good CMC and developability, superior to nanobody and ScFv
● Similar CMC process to monoclonal antibodies,allowing scaling up
● Differentiated from DuoBody ®, STAR-Lite platform allows one-cell manufacturing
● Rational design based on biology, related to disease setting
Bispecific Antibody Platform
Hy-BEAM platform has been successfully applied to multiple tumor ADCs

Parallel Conjugation
Multi-Payload
Stable Conjugation

● Site-specific conjugation yields homogeneous antibody-drug conjugates with defined drug-to-antibody ratios, enabling consistent therapeutic efficacy and improved safety profiles.

● Hydrophilic Linker, suitable for ADC development of high DAR, potentially enhancing the efficacy of the ADC.

● Greater therapeutic window in animal models, could be further improved/combined with other novel payloads

● Integrating STAR-Lite platform to avoid light chain mismatch, especially for BsAb ADCs ensuring better functionality of molecules with complex structure

● Good developability and excellent serum stability.

Bispecific ADC Expand Therapeutic Window
Bispecific ADC can be the optimal solution to improve target specificity and expand therapeutic window
MOA1: Dual Signaling Inhibition
MOA1: Dual Signaling Inhibition

Bispecific ADC inhibit two signaling pathways simultaneously, potentially leading to synergistic effects in cancer treatment. By targeting multiple pathways to overcome drug resistance that often hampers traditional therapies typically focus on a single pathway.

MOA2: Improve Target Specificity
MOA2: Improve Target Specificity

Bispecific ADCs can specifically recognize and bind to tumor cells expressing two different target antigens simultaneously. The specificity spares normal cells that express only one of the antigens, potentially reducing off-target effects and increasing safety.

MOA3: Enhance Internalization
MOA3: Enhance Internalization

By binding two different epitopes on the same antigen molecule, a ternary complex is formed, which can enhance the rate of antigen internalization. This improved internalization rate promotes the efficacy of the ADC

MOA4: Avidity Expand Therapeutic Window
MOA4: Avidity Expand Therapeutic Window

Bispecific ADCs target tumor cells through avidity, which reduces the likelihood of affecting normal cells. The selective targeting improves the specificity and safety of drug, leading to an expanded therapeutic window.
