Clinical Study Report (ICH E3)
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
An integrated report of a clinical trial’s methods, results, and statistical analyses, structured in the ICH E3 format so it can be evaluated independently by regulators, ethics committees, and other readers without needing separate access to the raw dataset. The CSR is the primary document supporting marketing applications and post-trial regulatory decisions.
The harmonized ICH E3 structure — synopsis, methods, results organized by endpoint, safety findings, and appendices including the protocol, statistical analysis plan, and case narratives — lets regulators across regions review a trial in a consistent, predictable format regardless of where it was conducted.
The CSR is the vehicle through which the pre-specified Statistical Analysis Plan is executed and reported; any deviation from that finalized plan must be disclosed and justified within the report rather than presented as though it had been planned all along.
Beyond its role in marketing applications, the CSR increasingly feeds public clinical trial results disclosure and registry obligations, making its accuracy and completeness relevant to audiences well beyond the reviewing regulator.
