EU MDR · ISO 14155 · Pre-market
Pre-market clinical investigations, built for Notified Body approval.
For high-risk devices, literature and equivalence no longer clear the bar. A well-designed pre-market study is often the only route to CE mark. Here are the four pillars and when you need one.

Led by authority
Protocols designed by clinical and regulatory specialists.
A pre-market study that clears review is designed by people who know how Competent Authorities and Notified Bodies read a protocol.

Distinction confirmed by an independent third party, the CVBF, also an awardee of the xShare × EUCROF Open Call.
CVBF coverage →The four pillars
Four frameworks. All must hold.
The move from the MDD to EU MDR altered the path to market. A pre-CE mark investigation must satisfy multiple overlapping frameworks — and failure in any single pillar means rejection by a Competent Authority or Notified Body.
EU MDR Annex XV
Defines the strict legal requirements for clinical investigations in Europe: protocol structure, investigator brochures and sponsor obligations.
ISO 14155
The core Good Clinical Practice standard for medical devices: how trials must be designed, conducted and recorded.
GDPR
Patient data protection: pseudonymisation, explicit informed consent and certified health-data hosting (e.g. HDS in France).
Declaration of Helsinki
The ethical bedrock: patient safety and well-being prioritised over scientific or commercial interests.
When you need a study
By device class.
Not every device needs a new trial. The obligation depends on class and the availability of existing clinical data.
| Device class | Clinical evidence requirement | Pre-market study? |
|---|---|---|
| Class I & IIa | Clinical evaluation from literature, post-market data of equivalents and bench testing. | Rarely — only for novel technology, materials or a new intended purpose with no equivalent. |
| Class IIb | Comprehensive CER; equivalence claims heavily scrutinised. | Frequently — unless strict biological, technical and clinical equivalence is proven. |
| Class III & implantables | Exceptional scrutiny; Article 61 mandates investigations. | Almost always — exceptions are extremely narrow (e.g. legacy transition with robust data). |
Crucial regulatory update
EUDAMED registration, before first patient.
Managing an ISO 14155 pre-market investigation is now inextricably linked to EUDAMED. Sponsors and Clinical Project Managers must complete administrative workflows before recruiting a single patient.
Before recruitment
- Obtain a Single Registration Number (SRN) to identify the sponsor across EUDAMED
- Register the clinical investigation, including SADE reporting and annual progress reports
- Align the protocol, the CIP and the submission with the target Competent Authority — see our MDCG 2021-8 guide
