Enhancing Conjugation Chemistry for Unlocking Synergistic Potential In Dual Payload ADCs
9:30 am Next-Generation Multi-Payload ADCs: How Site-Selective Conjugations Enable New Modalities
- Potential of dual-payload ADCs and challenges presented by traditional conjugation approaches
- Review of approaches to manufacturing dual-payload ADCs, with focus on the CysTyr platform for site-specific conjugation

10:00 am Repurposing the Maleimide Moiety of Linker-Payloads for Conjugation via Cycloaddition Reactions. Development of a Site-Specific Conjugation Approach via Transglutaminase and Diels-Alder Processes
This presentation will focus on the development of a novel two-step conjugation approach that combines the site specificity of the transglutaminase reaction with the reliability of the well-known Diels-Alder reaction. Attendees will gain insight into:
- Re-purposing the maleimides for conjugation to antibodies. A different application that specifically conjugates via cycloaddition reaction versus conjugation to interchain disulfides or engineered cysteines.
- Design and synthesis of diene-containing linkers for site specific transglutaminase conjugation. Modulation of the reactivity of the dienes for conjugation of two different payloads to generate dual-payload ADCs.
- Evaluation of the in vitro and in vivo activity of the ADCs generated via this transglutaminase – Diels-Alder approach, including the assessment of their stability.
- Highlight the importance of collaborations with Contract Research Organizations (CROs) for discovering and developing novel linker and conjugation technologies
