E3 – Structure and Content of Clinical Study Reports
Guideline number: E3
Status: Implementation (Step 5)
Adopted (Step 4): 30 November 1995
The ICH Harmonised Guideline was finalised under Step 4 in November 1995. This document describes the format and content of a clinical study report that will be acceptable to all regulatory authorities of the ICH regions. It consists of a core report suitable for all submissions and appendices that need to be available but will not be submitted in all cases.
The ICH Harmonised Guideline was finalised under Step 4 in July 1997. This document covers the preclinical safety testing requirements for biotechnological products. It addresses the use of animal models of disease, determination of when genotoxicity assays and carcinogenicity studies should be performed, and the impact of antibody formation on duration of toxicology studies.
An addendum was proposed to provide clarification on S6 and an update of the following topics discussed in the original ICH S6 Guideline: species selection, study design, immunogenicity, reproductive and developmental toxicity and assessment of carcinogenic potential. The Harmonised addendum provides further complementary guidance to the S6 Guideline and helps to define the current recommendations and reduce the likelihood that substantial differences will exist among regions.
The addendum reached Step 4 of the harmonisation process in June 2011 and was integrated as part II in the core Guideline that was then renamed S6(R1).

Q+A implementation
Since reaching Step 4 and publication within the ICH regions, experiences by all parties with the implementation of the E3 Guideline have resulted in the need for some clarification. This supplementary Questions and Answers document intends to clarify key issues. In July 2012, minor typographical errors were corrected in the Answer to Question 6 and the document was renamed R1.
