Academic investigators' interest in promoting specified clinical trials†:†Questionnaire survey before and after implementation of the Clinical Trial Act.

ABSTRACT

Background  Enforcement of the 2018 Clinical Trials Act (CTA) in Japan resulted in strict and complicated regulations surrounding intervention studies. Few Japan-specific measures have been developed to promote intervention studies in Japan despite concerns about CTA's negative influence on such studies. Therefore, this study examined the changes in academic investigators' interest in conducting clinical studies before and after enforcement of the CTA to determine measures to promote specified clinical trials. Methods  We conducted a questionnaire survey with investigators belonging to the Institute of Biomedical Sciences, Tokushima University Graduate School, before and after enforcement of the CTA. Results  Investigators had lesser interest in intervention studies in the post-questionnaire survey (post) group than in the pre-questionnaire survey (pre) group. Their desire for "project management" was significantly higher in the post-group than in the pre-group. Their desire for "support for preparing documents when conducting specified clinical trials" was significantly higher in the group interested in conducting specified clinical trials than that in the not-interested group. Conclusion  We revealed that investigators were highly interested in "project management" and "support for preparing documents when conducting specified clinical trials" after enforcement of the CTA. Measures for these desires may promote specified clinical trials. J. Med. Invest. 68 71-75, February, 2021.
