A Decade After Checkpoints: What Do We Know, What Do We Need to Know?

Daniel S Chen, MD, PhD, is the founder of Engenuity Life Sciences, former Vice President, Global Head of Cancer Immunotherapy Development at Genentech/Roche and former Chief Medical Officer for IGM Biosciences. He received a BS degree in Biology from the Massachusetts Institute of Technology (1990), a PhD in Microbiology & Immunology (1996) and MD (1998) from the University of Southern California. His PhD work and publications focused on “Early Events in Coronavirus Infection.” Dr Chen completed an Internal Medicine Residency and Medical Oncology Fellowship at Stanford University (2003). He went on to complete a Post-doctoral fellowship with Mark Davis in Immunology, where he was a Howard Hughes Medical Institute Associate. He also ran the metastatic melanoma clinic at the Stanford Cancer Center from 2003-2006. In that time, he studied human anti-cancer immune responses pre- and post- cancer vaccination and cytokine administration to determine why anti-tumor immune responses were not more clinically effective. He received a U19 grant to develop better immunologic tools to interrogate human immune responses and ultimately patented the MHC cellular microarray to detect and functionally characterize antigen-specific T cell states. He continued as Adjunct Clinical Faculty at Stanford from 2006-2016, where he cared for melanoma patients. At Genentech from 2006-2018, Dr Chen focused on the clinical development of anti-angiogenic and immune modulatory targeted therapies in both early and late Development, as well as the diagnostic tools to aid their development. This included leading the clinical development for atezolizumab, a PD-L1 inhibitor, from the time the program was in research through IND, Phase I, Phase II, Phase III, to filing and approvals in multiple indications worldwide. At IGM Biosciences, Dr Chen focused on the development of novel engineered multivalent and multispecific therapeutics and helped lead this from preclinical to having multiple therapeutics in the clinic in Phase I/II. He is a reviewer for Nature, Immunity, Journal for Immunotherapy of Cancer and Clinical Cancer Research, served on the Board of Directors for SITC, has been a recurring session organizer and session chair for PEGS Europe on engineered therapeutics since 2019, gave the keynote presentation at the AACR NCI EORTC Annual Meeting 2014 and presented at the US Congressional Briefing on Immuno Oncology in 2017. He has continued to publish with academic and industry collaborators in the field of cancer immunotherapy, including the often-referenced Chen and Mellman manuscripts, “Oncology meets Immunology: the Cancer-Immunity Cycle,” “Elements of cancer immunity and the cancer-immune set point” and the Hegde and Chen manuscript “Top 10 Challenges in Cancer Immunotherapy.”
