Harmonisation achievements in the Quality area include pivotal milestones such as the conduct of stability studies, defining relevant thresholds for impurities testing and a more flexible approach to pharmaceutical quality based on Good Manufacturing Practice GMP risk management. This Guideline provides recommendations on stability testing protocols including temperature, humidity and trial duration for climatic Zone I and II.

Furthermore, the revised document takes into account the requirements for stability testing in Climatic Zones III and IV in order to minimise the different storage conditions for submission of a global dossier.

This forms an annex to the main stability Guideline, and gives guidance on the basic testing protocol required to evaluate the light sensitivity and stability of new drugs and products. It extends the main stability Guideline for new formulations of already approved medicines and defines the circumstances under which reduced stability data can be accepted. This document describes general principles for reduced stability testing and provides examples of bracketing and matrixing designs. Furthermore, it provides examples of statistical approaches to stability data analysis.

The scope of the revision of ICH Q2 R1 will include validation principles that cover analytical use of spectroscopic or spectrometry data e. The guideline will continue to provide a general framework for the principles of analytical procedure validation applicable to products mostly in the scope of Q6A and Q6B.

Q14 Analytical Procedure Development Guideline.

The new q22a is proposed to harmonise the scientific approaches of Analytical Procedure Development, and to provide the principles relating to the description of Analytical Procedure Development process. This new guideline is intended to improve regulatory communication between industry and regulators and facilitate more efficient, sound scientific and risk-based approval as well as post-approval change management of analytical procedures.

This identifies the validation parameters needed for a variety of analytical methods. It also discusses the characteristics that must be considered during the validation of the analytical procedures which are included as part of registration applications. It extends the Guideline Q2A to include the actual experimental data required, along with the statistical interpretation, for the validation of analytical procedures.

The Guideline on Methodology has been incorporated into the Guideline guidflines Text in November and then renamed Q2 R1without any changes in the contents of the two Guidelines.

The Guideline addresses the chemistry and safety aspects of impurities, including the listing of impurities in specifications and defines the thresholds for reporting, identification and qualification.

The revision of the guideline has allowed clarifying some inconsistencies, to revise the decision tree, to harmonize with Q3B and to address some editorial issues.

Quality Guidelines : ICH

The Attachment 2 of this guideline has been revised under Step 4 without further public consultation on 25 October Q3A R2. This Guideline has been first revised and finalised under Step 4 in February It complements the Guideline on impurities guivelines new drug substances and provides advice in regard to impurities in products containing new, chemically synthesized drug substances.

Guideline Guideline specifically deals with those impurities which might arise as degradation products of the drug substance or arising from interactions between drug substance and excipients or components gyidelines primary packaging materials.

The Guideline sets out a rationale for the reporting, identification and qualification of such impurities based on a scientific appraisal of likely and actual impurities observed, and of the safety implications, following the principles elaborated in the parent Guideline. Threshold values for reporting and control of impurities are proposed, based on the maximum daily dose of the drug substance administered in the product.

This recommends the use of less toxic solvents in the manufacture of drug substances and dosage forms, and sets pharmaceutical limits for residual solvents organic volatile impurities in drug products. Limit values for three residual solvents in drug products were revised on basis of the newly recognised toxicity data; lower PDE for N-Methylpyrrolidone being kept in Class 2 limited by health-basis and for Tetrahydrofuran and Cumene being placed into Class 2 from Class 3 no health-based.


A corrigendum to calculation formula lch NMP was subsequently approved on 28 October As per the new coding rule, they were incorporated into the core Guideline in November Additionally, the MC approved the publication of Support Documents 1, 2 and 3, which include the summaries of the toxicity data from which PDEs were derived.

This guidance aims to provide a global policy for limiting metal impurities qualitatively and quantitatively in drug products and ingredients. An additional Guideline Q3C was developed to provide clarification of the requirements for residual solvents. ICH Q3D Elemental Impurities is a quality guideline for the control of elemental impurities in new drug products medicinal productsand it establishes Permitted Daily Exposures PDEs for 24 Elemental Impurities EIs for drug products administered by the oral, parenteral and inhalation routes of administration.

In addition, guidance is provided in Q3D on how to develop an acceptable level for EIs for drug products administered by other routes of administration. EC, Europe – Deadline for comments by 16 August Products administered on skin and its appendages e.

Throughout the development of the Q3D Guideline, external audiences, constituents and interested parties have clearly communicated the complexity of the implementation approaches for this guideline. While the Q11 Guideline provides the framework, it cannot provide the detailed examples covering the breadth of q2 case studies for fuidelines within scope of the guideline. Consequently, the ICH SC considered that the development of a comprehensive training programme and supporting documentation sponsored by ICH was necessary to ensure the proper interpretation and effective utilisation by industry and regulators alike to enable a harmonised and smooth implementation of Q3D on a global basis.

Q6A activity provided the framework on how to set specifications for drug substances to address how regulators and manufacturers might avoid setting or agreeing to conflicting standards for the same fuidelines, as part of the registration in different regions. The three organisations conduct their harmonisation efforts through a tripartite pharmacopeial harmonisation program known as the Pharmacopoeial Discussion Group PDG.

The pharmacopoeial authorities, working together through the Pharmacopoeial Discussion Group PDGhave been closely involved with the work of ICH since the outset and harmonisation between the major pharmacopoeias, which started before ICH, has proceeded in parallel.

The ICH Steering Committee receives regular reports on the status of pharmacopoeial harmonisation at its meetings. This document describes a process for the evaluation and recommendation by the Q4B Expert Working Group EWG of selected pharmacopoeial texts to facilitate their recognition by regulatory authorities for use as interchangeable in the ICH regions and since in Canada.

Following favourable evaluations, ICH will issue topic-specific annexes with information about these texts and their implementation. Implementation of the Q4B annexes is intended to avoid redundant testing by industry. Sub-Visible Particles General Chapter. Microbial Enumeration Tests General Chapter.

Tests for Specified Micro-organisms General Chapter. For each regulatory region this pharmacopoeial text is non-mandatory and is provided for informational purposes only. It contains the Interchangeability Statement from Health Canada. This is concerned with testing and evaluation of the viral safety of biotechnology products derived from characterised cell lines of human or animal origin.

The purpose is to provide a general framework for virus testing experiments for the evaluation of virus clearance and the design of viral tests and clearance evaluation studies. Please note that a typographic error has been corrected on 23 September on Table A The correction was integrated in the Guideline that was then renamed Q5A R1.

It advises on the types of information that are considered valuable in assessing the structure of the expression construct used to produce recombinant DNA derived proteins.

Therefore, this guideline is intended to assist in the collection of relevant technical information which serves as evidence that the manufacturing process changes will not have an adverse impact on the quality, safety and efficacy of the drug product.

The document does not prescribe any particular analytical, nonclinical or clinical strategy. The main emphasis of the document is on quality aspects. This addresses the process of selecting tests and methods and setting specifications for the testing of drug substances and dosage forms. Account has been taken of the considerable guidance and background information which are present in existing regional documents. This document provides guidance on justifying and setting specifications for proteins and polypeptides which are derived from recombinant or non-recombinant cell cultures.


The scope of this part is initially limited to well-characterised biotechnological products, although the concepts may be applicable to other biologicals as appropriate. In view of the nature of the products, the topic of specifications include in-process controls, bulk drug, final product and stability specifications and give guidance for a harmonised approach to determining appropriate specifications based on safety, process consistency, purity, analytical methodology, product administration and clinical data considerations.

Recently, however, attention has focused on the need to formalise GMP requirements for the components of pharmaceutical products – both active and inactive. With respect to the latter representatives from China, India and Australia have been invited to participate.

Experience gained with the implementation of the Guidrlines Q7 Guideline since its finalisation in shows that uncertainties related to the interpretation of some sections exist. Technical issues with regard to GMP of APIs — also in context q2x new ICH Guidelines – are addressed in this Question guidrlines Answer document in order to harmonise expectations during inspections, to remove ambiguities and uncertainties and also to harmonise the inspections of both small molecules and biotech APIs.

This Guideline is intended to provide guidance on the contents of Section 3. The guideline does not apply to contents of submissions for drug products during the clinical research stages of drug development. However the principles in this guideline are important to consider during these stages. This guideline might also be appropriate for other types of products.

To determine the applicability of this guideline for a particular type of product, applicants should consult with the appropriate regulatory authorities. The annex provides further clarification of key concepts outlined in the core Guideline. In addition, this annex describes the icg of quality by design QbD.

The annex is not intended to establish new standards: Where a company chooses to apply quality by design and quality risk management Q9: Quality Risk Managementlinked to an appropriate pharmaceutical guixelines system, then opportunities arise to enhance science- and risk-based regulatory approaches see Q The document with the first and second set of Points to Consider Document was finalised in June and Novemberrespectively.

This Guideline applies to pharmaceutical drug substances and drug products, including biotechnology and biological products, throughout the product och. The elements of Q10 should be applied in a manner that is appropriate and proportionate to each of the product lifecycle stages, recognising the differences among, and the different goals of each stage.

This new guidance is proposed for Active Pharmaceutical Ingredients APIs harmonising the scientific and technical principles relating to the description and guudelines of the development and manufacturing process CTD sections S 2.
