Differences in EU and US 510(k) Market Approval

Often asked by sponsor pharma and medical device manufacturers - is there a difference in clinical criteria and regulatory submission requirements? Differences in Class II and Class III medical device 510(k) regulatory clearance processes do exist. In particular is the process pertaining to issuance for a 510(k) medical device CE Mark. The EU CE Mark process requires medical device demonstration of safety only, and not efficacy and relies heavily on non-governmental opinion leaders or "Notified Bodies (NBs)" to regulate acceptance criteria, regulatory process, approval registration and post-approval post marketing surveillance for safety. In contrast, approval in the US of a new moderate to high risk Class II or Class III medical device requires demonstration of both safety and efficacy and is more regulated by a central governmental agency, CDRH/FDA. European Union Member Countries most often utilize CE review and approval from NBs, particularly because there is a huge savings in clinical development and clinical submission costs and thus time, with shorten timelines to registration and marketed medical device. Remember, EU approval is based only on data and documentation relating to safety and thus the NBs are often seen and chosen as a quick outlet to success and market CE approval. NBs can issue the CE Mark, they are independent, commercial organizations which implement regulatory control, monitor performance and safety of EU approved Class II or Class III medical devices.

  • review
  • monitor
  • audit
  • critique medical device design
  • assess safety
  • verify quality systems
  • review clinical submission data and documentation
  • guide regulatory process
  • approve medical devices
  • issue CE Marks
  • establish EU post marketing safety surveillance programs
  • regulate country-specific requirements and governance.

A medical device sponsor or manufacturer is free to choose an NB within the European Union. Within the European Union, there are more than 50 active NBs to date currently reviewing CE applications and registrations.

In the US, a 510(k) application is submitted to CRDH/FDA. The medical device must be safe and efficacious. The 510(k) application typically requires prospective, randomized, controlled clinical trials. To receive clearance from CDRH/FDA, clinical trial results must demonstrate safety, performance and efficacy, significantly demonstrate acceptable intended use. Clinical trials supporting a Class II or Class III medical device 510(k):

  • includes ~800 patients
  • multi-center
  • randomized
  • controlled
  • comparative.

A typical clinical trial including 800 patients with the above bulleted design criteria will cost the medical device sponsor or manufacturer 10M-20M, 24 months to perform, 6-8 months to prepare and submit depending on literature, references and supported by previously submitted "global" supplemental and supportive data from CE Marks, if applicable.
