Fostering IRB collaboration for review of international research.

This article presents a review of the literature, summarizes current initiatives, and provides a heuristic for assessing the effectiveness of a range of institutional review board (IRB) collaborative strategies that can reduce the regulatory burden of ethics review while ensuring protection of human subjects, with a particular focus on international research. Broad adoption of IRB collaborative strategies will reduce regulatory burdens posed by overlapping oversight mechanisms and has the potential to enhance human subjects protections.
