June 10, 2025 | In this bonus episode of The Chain, Daniel Chen, MD, PhD, founder and CEO of Synthetic Design Lab, returns for the Science Commune segment and speaks with Keith Flaherty, MD, FAACR, professor of Medicine of Harvard Medical School and president-elect of AACR. They discuss Flaherty’s prolific career; how his background led him to pursue a career in medicine; how public and private sectors are coming together in oncology around collaborations; reflections on targeted therapies and technologies; optimism around how AI will impact society and the future of medicine positively; and how we need to detect and treat disease early.
GUEST BIO
Keith T. Flaherty, MD, FAACR, Professor of Medicine, Harvard Medical School; and President-Elect, AACR
Dr. Flaherty is Director of Clinical Research at the Massachusetts General Hospital Cancer Center, and Professor of Medicine at Harvard Medical School. As described in the more than 300 peer reviewed primary research reports he has authored or co-authored, Dr. Flaherty and colleagues made several seminal observations that have defined the treatment of melanoma when they established the efficacy of BRAF, MEK and combined BRAF/MEK inhibition in patients with metastatic melanoma in a series of New England Journal of Medicine articles for which Dr. Flaherty was the first or senior author. He was the principal investigator of the NCI MATCH trial, the first NCI-sponsored trial assigning patients to targeted therapy independent of tumor type on the basis of DNA sequencing detection of oncogenes. Dr. Flaherty joined the NCI Board of Scientific Advisors in 2018 (chair 2021-23), AACR Board of Directors in 2019, and was elected President of AACR in 2025. Dr. Flaherty co-founded Loxo Oncology in 2013 and Scorpion Therapeutics in 2020, serving on the board of directors through the acquisitions of both by Eli Lilly in 2019 and 2025. He co-founded X4 Pharmaceuticals (NASDAQ: XFOR), privately held Strata Oncology (2015), Apricity Oncology (2017), Gyges Oncology (2020), Khora Therapeutics (2024), and Monimoi Therapeutics (2025). He has served on the boards of directors for Clovis Oncology, Kinnate BioPharma, and Checkmate Pharmaceuticals (until its acquisition by Regeneron in 2022), along with Loxo Oncology, Strata Oncology and Scorpion Therapeutics.
MODERATOR BIO
Daniel Chen, MD, PhD, Founder & CEO, Synthetic Design Lab
Daniel S. Chen, MD, PhD, is the founder of Engenuity Life Sciences and founder and CEO of Synthetic Design Lab, 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.” Daniel 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, Daniel focused on the clinical development of anti-angiogenic, antibody drug conjugates 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, Daniel focused on the development of novel engineered multivalent therapeutics and helped lead this from pre-clinical 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.”
