Dr. Charles Weijer from Western University (Canada) explored the evolving ethical landscape of modern randomized
controlled trials and their implications for research practice. As Professor of Medicine (Critical Care) and Philosophy,
Dr. Weijer brought unique expertise from his leadership in developing the first international ethics guidelines for cluster randomized
trials and his work on WHO guidance for health policy research.
Attendees learned how pragmatic RCTs, designed to inform real-world clinical decisions, challenge traditional informed consent approaches when
conducted across diverse patient populations and complex healthcare settings. Dr. Weijer examined why cluster RCTs, which randomize groups rather than individuals,
require rethinking research ethics beyond individual participant protection, and how these challenges offer opportunities to deepen our understanding
of core ethical principles in clinical research.
