MDCG 2021-8 – Clinical investigation application/notification documents

Eclevar medtech MCDG

MDCG 2021-8Clinical investigation application/notification documents 



EUDAMED (electronic system referred to in Article 73 of the MDR) was deemed to be functionally in June 2022, instead of 26 May 2021, but this is still delayed.  Per MDR 2017/745 Sponsors of clinical investigations are required to submit an application/notification to participating Member State(s) via EUDAMED. 

The MDCG created guidance MDCG 2021-8 to support Sponsors and Competent Authorities in the submission processes for clinical investigation application/notification in the absence of the European EUDAMED. 


MDCG 2021-8 Content: 

The main part of this guidance document are the six Annexes included in and downloadable on the last page of this document. 

These forms and templates provided by the MDCG may be helpful for the Competent Authorities and sponsors, though it is always requested to check with the relevant NCA if they require their own official application forms to be used.  

Insofar as possible, the clinical investigation application/notification form includes the same data fields to the EUDAMED system in development and will be used until the EUDAMED module for clinical investigations is fully functional. 

The Guidance also highlights the MDCG 2021-1 Rev.1, see more information below in “Other helpful MDCG Guidance”.

Annex 5: Clinical investigation supporting documents – Appendix of documents to attach  

The use of the checklist is not mandatory, but is recommended to be used for traceability, in conjunction with the document clinical investigation application form. 

The relevant NCA regarding expectations should always be checked, as there might be additional required documents in a single Member state.  

Mandatory documents required to support a submission with respect to Regulation 745/2017 are: 

  • Cover letter 
  • Application form 
  • Investigator’s Brochure (including any annexes) (if applicable)

Annex 6: Checklist of general safety and performance requirements, Standards, common specifications, and scientific advice  

This is well known from the essential requirements checklist under MDD/AIMDD.

MDR 2017/745 Annex XV, chapter II, section 2.7 lists this document to be included in the submission package for information on investigational medical devices.  

New to this checklist is the first part to include information on standards, common specifications, and scientific advice obtained from expert panels according to articles 9 and 106 MDR (Provision of scientific, technical and clinical opinions and advice). For more information on this, see: 

  • COMMISSION IMPLEMENTING DECISION (EU) 2019/1396 of 10 September 2019, laying down the rules for the application of Regulation (EU) 2017/745 of the European Parliament and of the Council as regards the designation of expert panels in the field of medical devices
