A sponsor submits a dossier for regulatory review in South Africa with the following findings during inspection: Trial sites used trained pharmacists to conduct screening procedures under Principal Investigator oversight, but delegation logs were inconsistently updated. Biological samples were stored at correct temperatures, but calibration logs for freezer monitoring devices were missing for a 2-week period. Adverse events were recorded, but serious adverse event reporting to the sponsor was delayed by 72 hours in several cases. Statistical analysis plan was finalised after database lock but before unblinding. Source data verification was performed on 60 % of records instead of the planned 100 % due to staffing limitations. Which is the most serious regulatory concern?
