Conduct↦Safety↦Medicinal Product Safety Reporting↦Suspected Unexpected Serious Adverse Reaction
What is it? Why is it important?
A Suspected Unexpected Serious Adverse Reaction (SUSAR) is a SAE that is:
- Suspected to be related to the product under investigation (IMP)
- Unexpected, as the event has not yet been described in terms of its nature, intensity or frequency (e.g. based on the RSI: IB for non-licensed IMPs, product information for licensed MPs)
SUSARs are subject to expedited reporting, meaning that the event must be reported within a given timeframe.
A SUSAR in a double-blind study might require unblinding in order to establish a potential relationship with the product under investigation (IMP).
In order to prevent participants from being disqualified from the study, unblinding procedures must prevent the disclosure of the study’s treatment allocation (e.g. SP-INV, study staff). In order to treat participants with a SUSAR, the Site-INV must know the treatment allocation (e.g. treatment group or placebo)
What do I need to do?
As a Site-INV:
- Report all SAEs to the SP-INV within 24 hours of awareness
- If a SAE qualifies as a SUSAR, the SP-INV will require additional details needed to complete the SUSAR reporting form (CIOMS)
As a SP-INV:
- Assess SAE expectedness based on the RSI
- For SAEs that qualify as SUSARs, fill in the CIOMS form (e.g. based on reports provided by the Site-INV)
- Report SUSARs occurred at Swiss study site within:
- 7 days, for fatal events
- 15 days, for all other cases
- Report to:
- EC using the BASEC portal
- Swissmedic (e.g. for category B and C studies)
- All participating Site-INVs
For category A studies, report all SUSARs to Swissmedic within 15 days (e.g. through the Pharmacovigilance (PV) drug safety department, or the PV unit at your hospital).
Do not delay expedited reporting due to the lack of required information (e.g. Site-INV to SP-INV, SP-INV to PV). Applicable follow-up reports can be forwarded as they become available.
In multi-centre Swiss studies:
- The coordinating Site-INV might also take on SUSAR reporting responsibilities to participating local EC(s)
- A list of all SUSARs that have occurred at all study sites (including international sites) are summarised in the annual safety report
SUSAR documentation and reporting starts and is mandatory once the participant has signed the ICF until:
- Study termination (e.g. last study participant at last study visit), or
- The end of some predefined safety follow-up period (e.g. as defined in the study protocol)
