SAE reporting is a critical part of any Clinical Trial. The Investigator is responsible for the medical care of the trial subject and also ethically bound to report any SAE to the stakeholders involved in the clinical trial. The trial Investigator should report all SAEs to the drug regulatory body, sponsor of the trial, and the concerned ethics committee that approved the trial protocol within 24 hours of occurrence of the SAE. The drug trial sponsor is responsible for the ongoing safety evaluation of the investigational product or drug trial, reporting, and compensating the participant in case of any SAE.  SAE’s can be further categorized as expected or unexpected.
