International Comparison of Qualification Process for Medical Product Development Tools.

Introduction: Qualification of medical product evaluation tools is underway in the United States, Europe, and Japan to reflect the advancements in the basic science of medical products. In Europe and the U.S., Guidance of Guidances (GoG) policies that clarify regulators'processes, tasks, and methods of sponsor involvement are adopted to issue tool guidance. However, in Japan, a non-GoG type policy focusing on supporting the research and development for tools without defining a tool guidance-making process has been adopted.

Methods: In this study, an analytical framework for the lifecycle of development tools was constructed, including pre- and post-tool qualification processes, to compare the two above-mentioned approaches. For this study, Japanese cases were selected as experimental cases, whereas Western cases served as controls. The progress of tool qualification and composition of deliverables were analyzed.

Results and conclusions: It was indicated that in the GoG type policy, in which processes are defined, and involvement methods are clarified, tool qualification can progress more smoothly than in a non-GoG type policy. This policy indicates that deliverables may have a consistent composition. Contrastingly, GoG-type policies alone present challenges in connecting upstream tools for R&D support.
