EudraCT Number
A unique identification number assigned to clinical trials conducted in the European Economic Area, used in the EU Clinical Trials Register. The format is YYYY-NNNNNN-CC. EudraCT numbers complement NCT numbers and may appear on trials conducted primarily in European sites.
Technical Context
EudraCT (European Union Drug Regulating Authorities Clinical Trials Database) is maintained by the EMA and contains information on all clinical trials conducted in the European Economic Area since 2004. The number format is YYYY-NNNNNN-CC where YYYY is year, NNNNNN is a sequential number, and CC is a check digit. EudraCT records include: protocol information, regulatory and ethics approvals, and (since 2014) summary results for paediatric and Phase II-IV adult trials. The EU Clinical Trials Register (clinicaltrialsregister.eu) is the public-facing portal. Under the new Clinical Trials Regulation (CTR 536/2014), the Clinical Trials Information System (CTIS) is replacing EudraCT as the single submission point for EU clinical trials.
