M1 – MedDRA: Medical Dictionary for Regulatory Activities

Guideline number: M1
Status: Implementation (Step 5)
Adopted (Step 4): 1 January 1999

The development of a Medical Dictionary for Regulatory Activities (MedDRA) was approved by the ICH Steering Committee in 1997, and the terminology was launched in 1999. Due to the development of this topic over the years, all information about MedDRA and the Points to Consider documents developed for every MedDRA version are available on the MedDRA page of the ICH website. Please also visit the official MedDRA website.

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).
