In Memoriam: Dr. Brian Feagan
Office of the Dean
With sadness, we share the passing of Dr. Brian Feagan on November 23, 2025.
Brian was a professor in the Departments of Medicine and Epidemiology and Biostatistics at Western University and a gastroenterologist at London Health Sciences Centre. A global leader in the design and execution of large-scale clinical trials, he dedicated his career to improving care for people living with Crohn’s disease and ulcerative colitis.
His research, vision and leadership touched millions of lives across the globe.
Born in London, Ontario, Brian made the city his lifelong home. He attended Western University for his undergraduate and medical training, earning an Honors Bachelor of Science in bacteriology and immunology in 1977 and Doctor of Medicine in 1983. In addition, he completed a master’s degree in medical microbiology at the London School of Hygiene and Tropical Medicine and advanced training in epidemiology and biostatistics at McMaster University.
Brian often said he became a scientist because it was clear early in his medical training that too many treatment decisions were made without strong evidence. He was proud to contribute to the growing movement of evidence-based medicine, and he took great satisfaction in conducting research that directly shaped patient care.
Building on the foundation laid by Dr. Henry Barnett and the London Clinical Trials Research Group, Brian established Alimentiv Inc. (formerly Robarts Clinical Trials Inc.), where he served as Chief Executive Officer (1997 – 2016), before stepping into the role of Senior Scientific Director.
As a principal investigator on more than 140 trials and author of over 500 papers and book chapters, his work has been cited more than 40,000 times, placing him among the top one per cent of cited scientists worldwide.
He was also a mentor to many trainees, colleagues and friends across clinical, academic and industry communities.
While he was internationally lauded for his outstanding contributions to medical science, Brian also filled his life with simple passions. He was a devoted Green Bay Packers fan, a lover of art, literature and world history, and enjoyed canoeing through northern Ontario in his younger years. He especially loved his cockapoo and grandchildren.
Brian will be dearly missed by his family, friends, colleagues and the countless patients whose lives were shaped by his commitment to better medicine. His legacy will continue to inspire and guide our community for years to come.
