As there are no regulatory detailed expectations on oversight by investigators on eCOA data, multiple approaches have been adopted across the industry (from log-in as evidence to notification/alerts or investigator signature on eCOA data). In general, as per other data sources, oversight for eCOA data should be continual and not once at the end of the study. In addition, oversight activities should be right-sized according to the criticality of the data and protocol requirements for compliance. Evidence of the oversight should be available during the conduct of the trial and enduring for the entire retention period. The aim of this webinar is to allow participants to share different approaches and any knowledge of current expectations by regulatory inspectors.
