Successful ADCs must achieve potent on-target cytotoxicity while minimizing off-target effects on healthy cells. Off-target toxicities to normal hematopoietic cells are the most frequently reported adverse events associated with ADCs. These off-target effects can be caused when normal cells express the ADC target. However, the unforeseen and unexpected off-target toxicities to the hematopoietic compartment, with targets not expressed on hematopoietic cells, suggest that linker stability and the highly potent payloads may play the most significant role in off-target toxicity. The featured speakers will also discuss in vitro assays to quickly evaluate these components and demonstrate how linker stability and payload selection contribute to these adverse outcomes.
Register for this webinar to gain practical strategies for advancing ADC development with confidence, whether you’re new to ADCs or optimizing your next therapeutic candidate.

Who Should Attend?
This webinar will appeal to:
- ADC developers and scientists
- Oncology drug developers and researchers
- Preclinical and translational scientists focused on in vitro assay development
- Biopharma professionals involved in ADC candidate selection and optimization
What You Will Learn
Attendees will:
- Understand why ADC programs benefit from a “fail faster” approach to reduce late-stage attrition and accelerate development
- Learn how early in vitro testing helps identify both on-target efficacy and off-target toxicity risks
- See how tumoroid models offer more physiologically relevant insights into ADC activity across diverse tumor types
- Explore how hematopoietic assays can predict off-target effects like myelosuppression and neutropenia
