ICH E3 (Structure and Content of Clinical Study Reports)

ICH E3 is the international guideline that defines the required structure, content, and appendices of a Clinical Study Report submitted to support marketing authorization of an investigational medicinal product.

E3 specifies 16 main sections (from Synopsis to References) and detailed appendix requirements (protocol, sample CRFs, IRB approvals, investigator listings, audit certificates, statistical methods, datasets). The 2012 Q&A addendum clarifies expectations around integrated reporting for multiple studies and abbreviated reports.

Adherence to E3 structure expedites regulatory review and is effectively non-negotiable for ICH-region submissions.
