What is it? Why is it important?

The discontinuation or interruption of a study must be notified to EC, and if applicable Swissmedic within:

  • 90 days, for HRO studies
  • 15 days, for ClinO and ClinO-MD studies
  • 24 hours, for ClinO-MD studies where study termination was due to safety reasons

What do I need to do?

As SP-INV notify:

  • EC by:
    • Submitting a notification form of study discontinuation or interruption via BASEC
  • Swissmedic by:
    • Completing a “FO submission form” available on the Swissmedic website
    • Submitting the document(s) by post, both in paper and electronic form (CD)

With study / research project discontinuation or interruption, provide details and rational as to why the study was stopped.

File notification forms in the TMF.
