S7B – The Non-Clinical Evaluation of the Potential for Delayed Ventricular Repolarization (QT Interval Prolongation) by Human Pharmaceuticals

Guideline number: S7B
Status: Implementation (Step 5)
Adopted (Step 4): 12 May 2005

The ICH Harmonised Guideline was adopted under Step 4 in May 2005. This Guideline describes a non-clinical testing strategy for assessing the potential of a test substance to delay ventricular repolarization. This Guideline includes information concerning non-clinical assays and integrated risk assessments.

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).
