AbbVie acquired ImmunoGen in 2024.



Lambert earned a Ph.D. in biochemistry from the University of Cambridge in 1976 and completed postdoctoral research at the University of California, Davis, and the University of Glasgow. He has authored over 130 peer-reviewed publications and was elected Fellow of the American Institute for Medical and Biological Engineering in 2016. Since 2018, he has advised biotechnology companies and venture capital firms on ADC technologies.



"John is one of the most respected pioneers in the ADC field and has contributed to the development of technologies and therapeutics that have had a major impact on cancer treatment worldwide," said Sébastien Plouffe, Defence's chief executive officer.



Defence Therapeutics develops its ACCUM platform for precision drug delivery, focusing on enhancing the effectiveness of ADCs and other biologics for cancer treatment.
