Ministerial Ordinance on Clinical Trial Standards (GCP for Devices)

Applicable ordinance​

The Good Clinical Practice standards for medical device clinical trials in Japan are established in:

  • Ministerial Ordinance on Standards for Clinical Trials of Medical Devices (医療機器の臨床試験の実施の基準に関する省令)
  • Often referred to as GCP Ordinance for Devices or Device GCP

This is separate from the GCP Ordinance for pharmaceuticals — device clinical trials are governed by device-specific GCP requirements.

GCP requirements for device clinical trials in Japan​

  • File a Clinical Trial Notification (CTN) with MHLW at least 30 days before first subject enrolment
  • Ensure the trial is conducted in accordance with the approved protocol
  • Monitor the trial at participating institutions
  • Report serious adverse events to MHLW
  • Audit the trial and maintain trial master file records

Investigator responsibilities:

  • Obtain and document informed consent from each subject
  • Conduct the trial in accordance with the protocol
  • Report adverse events to the sponsor promptly
  • Maintain investigator site file records

Ethics committee requirements:

  • Each participating institution must have the trial approved by an MHLW-accredited Ethics Committee (倫理審査委員会)
  • Approval must be obtained before any subject is enrolled at that site
  • Amendments to the protocol must be reviewed by the Ethics Committee before implementation

Written informed consent must be obtained from each subject before any trial procedure. The consent process and form must comply with specific content requirements in the GCP Ordinance. If a subject cannot consent personally (e.g. in an emergency), specific alternative consent provisions apply.
