E2A – Clinical Safety Data Management: Definitions and Standards for Expedited Reporting

Guideline number: E2A
Status: Implementation (Step 5)
Adopted (Step 4): 27 October 1994

The ICH Harmonised Guideline was finalised under Step 4 in October 1994. This document gives standard definitions and terminology for key aspects of clinical safety reporting. It also gives guidance on mechanisms for handling expedited (rapid) reporting of adverse drug reactions in the investigational phase of drug development.

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).
