New Codification as per November 2005 (Click here for more details)

S1A: Guideline on the Need for Carcinogenicity Studies of Pharmaceuticals

The tripartite harmonised ICH guideline was finalised (Step 4) in November 1995. This document provides a consistent definition of the circumstances under which it is necessary to undertake carcinogenicity studies on new drugs. These recommendations take into account the known risk factors as well as the intended indications and duration of exposure.

MHLW : Adopted April 97, PAB/PCD Notification No.315
FDA : Published in the Federal Register, Vol. 61, March 1, 1996, pages 8153

S1B: Testing for Carcinogenicity of Pharmaceuticals

The tripartite harmonised ICH guideline was finalised (Step 4) in July 1997. This document provides guidance on the need to carry out carcinogenicity studies in both mice and rats, and guidance is also given on alternative testing procedures which may be applied without jeopardizing safety.

EU : Adopted by CPMP, September 97, issued as CPMP/ICH/299/95
MHLW : Adopted July 1998, PMSB/ELD Notification No.548

S1C(R2): Dose Selection for Carcinogenicity Studies of Pharmaceuticals

This second revision has been approved by the ICH Steering Committee directly under Step 4 without further public consultation in March 2008.

Note 2 of the parent guideline has been deleted, and the text referring to the Notes has been revised. The title has been changed by deleting "& Limit Dose". 
The Addendum has been integrated in the text.

This document addresses the criteria for the selection of the high dose to be used in carcinogenicity studies on new therapeutic agents to harmonise current practices and improve the design of studies. 

In this revision, the pharmacokinetic endpoint of 25 is declared to be applicable also for pharmaceuticals with positive genotoxicity signals. This change has implications on "Refinement" (one of the 3R's) in enhancing the welfare, i.e., reducing the pain or discomfort of the animals at the MTD.

S2(R1): Guidance on Genotoxicity Testing and Data Interpretation for Pharmaceuticals Intended for Human Use

This guideline has been released for consultation under Step 2 of the ICH process on 6 March 2008. 
This guidance replaces and combines the ICH S2A and S2B guidelines: 

The purpose of the revision of this guideline is to optimize the standard genetic toxicology battery for prediction of potential human risks, and to provide guidance on interpretation of results, with the ultimate goal of improving risk characterization for carcinogenic effects that have their basis in changes in the genetic material. The revised guidance describes internationally agreed upon standards for follow-up testing and interpretation of positive results in vitro and in vivo in the standard genetic toxicology battery, including assessment of non-relevant findings.

S4:  Single Dose Toxicity Tests

Agreement was reached, at the time of ICH 1, in 1991, that the LD₅₀ determination should be abandoned for pharmaceuticals. The recommendation was published in the Proceedings of the First International Conference on Harmonisation, page 184.

S4:  Duration of Chronic Toxicity Testing in Animals (Rodent and Non-Rodent Toxicity Testing)

A tripartite, harmonised ICH guideline was finalised (Step 4) in September 1998. The recommendations are unchanged from those in the consultation draft issued in July 1997. The text incorporates the guidance for repeat-dose toxicity tests that was agreed at the time of ICH 1, in 1991 (reduction of the duration of repeat dose toxicity studies in the rat from 12 to 6 months).

S5(R2): Detection of Toxicity to Reproduction for Medicinal Products & Toxicity to Male Fertility

The core tripartite harmonised ICH guideline was finalised (Step 4) in June 1993. This document provides guidance on tests for reproductive toxicity. It defines the periods of treatment to be used in animals to better reflect human exposure to medical products and allow more specific identification of stages at risk.

The addendum to the core ICH guideline above with respect to male fertility studies was finalised (Step 4) in November 1995. The guideline has been amended on November 9, 2000, under the Maintenance Process.

S6(R1): Preclinical Safety Evaluation of Biotechnology-Derived Pharmaceuticals

This guideline has been released for consultation under Step 2 of the ICH process on 29 October 2009. 
The purpose of the addendum is to provide clarification on S6 and an update of the following topics discussed in the original ICH S6 guidance: species selection, study design, immunogenicity, reproductive and developmental toxicity and assessment of carcinogenic potential. Scientific advances and experience gained since publication of the original ICH S6 guidance call for this addendum.
This harmonised addendum will provide further complementary guidance to the S6 guideline and will help to define the current recommendations and reduce the likelihood that substantial differences will exist among regions.

S8 : Immunotoxicity Studies for Human Pharmaceuticals

The Guideline reached Step 4 of the ICH process on 15 September 2005.

This guideline addresses the recommendations on nonclinical testing for immunosuppression induced by low molecular weight drugs (non-biologicals). It applies to new pharmaceuticals intended for use in humans, as well as to marketed drug products proposed for different indications or other variations on the current product label in which the change could result in unaddressed and relevant toxicologic issues. In addition, the guideline might also apply to drugs in which clinical signs of immunosuppression are observed during clinical trials and following approval to market. The term immunotoxicity in this guideline will primarily refer to immunosuppression, i.e. a state of increased susceptibility to infections or the development of tumors.
It is beyond the scope of this guideline to provide specific guidance on how each immunotoxicity study should be performed. 
General guidance is provided in Appendix 1.
