    Electronic Data Capture

    Software systems used to collect, manage, and report clinical trial data electronically, replacing paper case report forms.

    Definition

    Electronic Data Capture (EDC) systems are validated software platforms used to design electronic Case Report Forms (eCRFs), collect clinical data from investigator sites, run edit checks, manage queries, and produce locked datasets for analysis. Common platforms include Medidata Rave, Veeva Vault EDC, Oracle InForm, and Castor. EDC systems generate audit trails, enforce role-based access, and integrate with related systems, Clinical Trial Management Systems (CTMS), eConsent, ePRO, randomization (IRT/IWRS), safety databases, and electronic Trial Master Files (eTMF).
    What the regulation says
    21 CFR Part 11 governs electronic records and signatures used in FDA-regulated activities. ICH E6(R3) and ISO 14155 require validated systems for trial data collection with audit trails, access controls, and data integrity safeguards (ALCOA+). FDA's 'Electronic Systems, Electronic Records, and Electronic Signatures in Clinical Investigations' guidance (2023, draft) updates the agency's expectations.

    What this means in practice

    EDC is foundational to modern clinical trial conduct. Sponsors must validate EDC systems per 21 CFR Part 11 (electronic records and signatures), maintain audit trails, and demonstrate data integrity meets ALCOA+ principles. For IDE device trials, EDC validation, user training records, and source data verification approach are routinely inspected by FDA bioresearch monitoring inspectors. The shift toward Risk-Based Monitoring (RBM) and Decentralized Clinical Trials (DCT) is built on EDC capabilities including remote source data review and real-time anomaly detection.
    Common pitfalls
    • •Treating EDC validation as a vendor responsibility, sponsors are accountable for the validation evidence in their environment, with their configuration.
    • •Skipping or shortcutting 21 CFR Part 11 audit-trail review during inspection readiness.
    • •Underestimating data migration risk when switching EDC platforms mid-study, FDA expects defensible mapping and re-validation.
