What is it? Why is it important?

Once the EC has assessed the application dossier:

  • The study is provided with a unique ID (e.g. consists of a BASEC identification number and/or an EC reference number)
  • An order is issued conveying its decision. In general, the decision states that study conduct is:
    • Granted: The study can start
    • Granted with conditions Changes or adaptations must be fulfilled within 30 days
    • Not granted: If resubmitted, the EC will consider the dossier as a new submission (e.g. the original BASEC ID is retained)

The EC order also includes:

  • Additional information regarding pending tasks
  • A summary of submitted documents. EC approval only applies to those documents that were submitted in the application dossier


The EC might also forward a list of outstanding questions to the SP-INV, which includes:

  • An order stating the decision of the EC
  • A list of pending questions
  • A separate document where any relevant questions & answers are entered (Word table)

What do I need to do?

In the event, approval was granted based on conditions:

  • Ensure to correctly answer all EC question(s)
  • If applicable, provide additional documents or make requested adaptations
  • Report back within the deadline (30 days)

Once the study has been fully approved, the SP-INV must ensure that:

  • The EC-identifier-number is included during any correspondence with EC
  • A robust document tracking system is in place, to ensure that only EC approved documents are used in the study
  • Any changes to EC approved documents are re-submitted for EC approval prior to implementation

Some studies also require Swissmedic / FOPH approval. Consequently, wait for all required approvals before starting the study.


In the event the EC requires you to answer some questions:

  • Write a cover letter
  • Complete the question & answer table
  • Make required changes or adaptations to relevant study documents (e.g. both in track-changes and clean version)
  • Create and include any additionally requested documents
  • Access BASEC to submit your updated application dossier

File all correspondence with EC, including the order of approval in the TMF, and if applicable in the local ISF.
