“The complexity is there’s an antibody component, linker-payloads with highly potent toxic agents that need high containment, and linking a biologic with a highly potent small molecule – it’s inherently challenging.”
Dr. Harch Ooi, VP of Manufacturing and Chemistry at IsoBio Inc., brings 17 years of specialized expertise in antibody-drug conjugate (ADC) manufacturing and external partnerships from Seagen (acquired by Pfizer in 2023). There, he contributed to the development and manufacturing of SGD-1006, the vedotin linker-payload that is used in Adcetris, Padcev, Tivdak, Polivy (from Genentech/Roche), and Emrelis (from Abbvie). Over the years, Dr. Ooi has witnessed the field’s dramatic transformation, from a single approved ADC in 2000 to a robust pipeline of 15 approved therapies today.
In the latest podcast episode, Harch explains why mastering ADC outsourcing strategy is crucial for biotechnology companies navigating this complex modality. He shares practical insights on CDMO selection, safety protocols, and operational strategies that drive success from early development through commercial launch.
