Tragically, the outbreak of Ebola that started in West Africa in 2014 has been far more extensive and damaging than any previous outbreaks. The duration of the outbreak has, for the first time, allowed the clinical evaluation of Ebola treatments. ⋯ General principles are outlined for trial designs intended to be deployed quickly, adapt flexibly and provide results soon enough to influence the course of the current epidemic rather than just providing evidence for use should Ebola break out again. Lessons are drawn for the conduct of clinical research in future outbreaks of infectious diseases, where the sequence of events may or may not be similar to the West African Ebola epidemic.

Pragmatic trials comparing "standard of care" treatments provide comparative effectiveness data to make practice of medicine more evidence-based. With electronic health records, recruiting and conducting such trials can be relatively inexpensive. But some worry that the traditional research ethics framework poses unnecessary obstacles and is not appropriate for evaluating such clinical trials. This concern is based on the view (which we call the "Standard of Care Principle") that such research is similar to usual clinical practice and therefore does not raise significant ethical issues since everyone in the research study will receive an accepted standard of care treatment. ⋯ The Standard of Care Principle is ethically inadequate and misleading even when it is applied to the pragmatic randomized clinical trial proposed as a paradigm case for its application.
