What is it? Why is it important?

The Annual Safety Report (ASR) is a document provided by the SP-INV to the EC and RA (e.g. Swissmedic), regarding a current summary of all safety relevant information in an ongoing study.


An ASR report must:

  • Be submitted for all studies under ClinO and ClinO-MD
  • Be submitted once a year to EC and Swissmedic (e.g. for Swissmedic only risk category B and C)
  • Contain a list of relevant safety events that occurred:
    • Since the last submitted ASR, or
    • Upon 1 year after study start (e.g. defined as the EC/RA approval date, whichever came first)
  • Describe the safety assessments of collected events (e.g. severity, seriousness, the potential causal relationship to the intervention, and expectedness)
  • Describe measures taken to ensure the safety of study participants
  • Include events that occurred at study sites located abroad

What do I need to do?

As a Site-INV submit all safety relevant information required for the preparation of the ASR report to the SP-INV.

As a SP-INV submit once a year an ASR to:


Based on study type, include in your ASR the following lists:

  • IMP studies: all SAEs and SUSARs
  • IMD studies: all reportable events (SADEs and DDs with SAE potential)
  • Other Clinical Trials: all SAEs for which a causal relationship with the intervention cannot be excluded
  • TrP / GT / GMO studies: all SAEs, SADRs, SUSARs, and quality defects


For international multi-centre studies with TrP/ GT / GMO:

  • Present data from study participants treated in Switzerland separately
  • For healthy volunteers, list all AEs irrespective whether they occurred in Switzerland or abroad
