An Electronic Trial Master File (eTMF) is a digital repository that stores essential documents demonstrating that a clinical trial was conducted in compliance with regulatory requirements.
eTMFs mirror the structure of the Trial Master File and support real-time oversight and collaboration across sponsors, CROs, and functional teams. They provide documented evidence of approvals, monitoring, safety reporting, vendor oversight, and study conduct activities. Regulators expect eTMFs to be complete, accurate, contemporaneous, and inspection-ready during the entire study lifecycle. A high-quality eTMF supports efficient inspections, strong governance, and defensible compliance posture.
