Knowing which countries to submit clinical trial results summaries to is the easy part. What becomes difficult is learning the intricacies and transparency requirements of every clinical trial registry globally, including the Japan Primary Registries Network (JPRN). Here is an overview of this registry:

Registry name: Japan Primary Registries Network (JPRN)

Country: Japan

Year established: 2007

Points of interest:

  • The JPRN is a primary registry in the WHO Network, with support from Japan’s National Institute of Public Health (NIPH)
  • The registry network consists of three registries:
    • University Hospital Medical Information Network (UMIN)
    • Japan Pharmaceutical Information Center (JAPIC)
    • Japan Medical Association – Center for Clinical Trials (JMACCT)
  • The JPRN allows users to search for clinical trial information in all three registries
  • Clinical trials in Japan are classified into two categories:
    • those performed by pharmaceutical companies or investigators acquiring marketing authorizations (MAs) of medical products under the Pharmaceutical Affairs Law, and
    • those performed by investigators, without the purpose of acquiring a MA
  • The Japanese government has cooperated with the WHO and encourages continued collaboration within the JPRN
  • The JPRN offers clinical trial information in both Japanese and English, in an effort to make information accessible globally and to Japanese citizens
  • The JPRN’s goal is to make clinical trial information accessible to researchers and clinicians and to aid in Japanese medical innovation
