Your Easy Guide to Clinical Studies

An Adverse Event (AE) is any untoward medical occurrence in a participant administered an Investigational Medicinal Product (IMP), but which does not necessarily have a causal relationship with the treatment.

 

AE is defined as:

• An unfavourable and unintended sign (e.g. abnormal laboratory finding), or
• A symptom or disease temporally associated with the use of an Investigational Medicinal Product (IMP)

 

In studies, the assessment of AEs is mandatory (e.g. based on HRA). Still, the extent of AE documentation and reporting depends on the risk-category of the study.

 

As required, AE documentation and reporting starts and is mandatory once the participant has signed the consent form (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)

As a Site-INV and SP-INV:

• Perform AE assessments. In the event of a serious event, proceed accordingly (e.g. SAE reporting)
• If applicable, document AEs in a standardised manner (e.g. patient-file and eCRF). Include any medical care provided to participants
• Follow reporting requirements as defined in the study protocol (e.g. reporting timelines from Site-INV to SP-INV, summary of all AEs in a study report and a clinical study report at the end of the study)

 

During study conduct, the requirement of AE documentation depends on study risk:

• Category A (low risk): has no documentation requirements except:
  • If required based on the study protocol
  • The study outcome / endpoint is the safety outcome of the study
• Category B (medium risk) and Category C (high risk): must document all AEs critical to the safety evaluation

 

Reporting must be done to Ethics Committee (EC), and as applicable to Swissmedic, including other relevant RAs international).
