Clinical Investigations of Medical Devices in Denmark

Clinical Investigations of Medical Devices in Denmark

1. Overview and Requirements

Clinical investigations of medical devices must be notified to the Danish Medicines Agency before initiation in Denmark. Sponsors (or their legal representatives) are responsible for submission. Investigations require approval from a research ethics committee, except for certain post-market studies.

2. Types of Investigations

  • Pre-market clinical investigations (PMCI) for non-CE marked or off-purpose devices.
  • Post-market clinical follow-up (PMCF) for CE-marked devices.
  • Performance studies for in vitro diagnostic devices (IVDs) under IVDR. Source: Danish Medicines Agency Clinical Investigations Page https://laegemiddelstyrelsen.dk/en/devices/clinical-investigations/

3. Notification and Application

Applications are submitted via the electronic system at kliniskeforsog.dk. Required documents include protocol, investigator's brochure, patient information, and ethics application. The Agency aims to process within 10 days for complete applications; incomplete ones trigger a 30-day clock-stop for supplements.

4. Ethics Committee Approval

All clinical investigations require research ethics committee approval, coordinated through the national system. PMCF investigations not posing additional invasive procedures may be exempt if justified.
