Comprehensive Guide to ICH Q11: Impurity Control Strategy in Drug Substance Development Testing Services Provided by Eurolab

ICH Q11: Impurity Control Strategy is a regulatory guideline developed by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH). The guideline provides recommendations for the control and identification of impurities in drug substances during development. In this section, we will provide comprehensive information about the relevant standards, legal and regulatory framework, international and national standards, standard development organizations, and their role.

Relevant Standards

The following standards are relevant to ICH Q11: Impurity Control Strategy:

  • ISO 17025:2005 (General requirements for the competence of testing and calibration laboratories)

  • ASTM E2553-10 (Standard Guide for Impurities in Pharmaceuticals)

  • EN 14636:2014 (Pharmaceuticals - Impurities in pharmaceutical substances)

  • TSE (Turkish Standards Institution) TS EN ISO 17025:2006 (General requirements for the competence of testing and calibration laboratories)

    • Legal and Regulatory Framework

    The legal and regulatory framework surrounding ICH Q11: Impurity Control Strategy is governed by various national and international regulations. These regulations require that pharmaceutical companies follow good manufacturing practices (GMP) and ensure that their products meet specific quality standards.

  • US FDA 21 CFR Part 211 (Current Good Manufacturing Practice in Manufacture, Processing, Packing, or Holding of Drugs)

  • EU GMP (Good Manufacturing Practice for Medicinal Products)

  • ICH Q7 (Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients)

    • International and National Standards

    ICH Q11: Impurity Control Strategy is based on the principles outlined in various international and national standards. These standards provide a framework for the control and identification of impurities in drug substances.

  • ISO 17025:2005 (General requirements for the competence of testing and calibration laboratories)

  • ASTM E2553-10 (Standard Guide for Impurities in Pharmaceuticals)

  • EN 14636:2014 (Pharmaceuticals - Impurities in pharmaceutical substances)

    • Standard Development Organizations

    Standard development organizations play a crucial role in developing and maintaining standards that govern ICH Q11: Impurity Control Strategy. These organizations include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

  • Turkish Standards Institution (TSE)

    • Role of Standard Development Organizations

    Standard development organizations are responsible for developing, maintaining, and publishing standards that govern ICH Q11: Impurity Control Strategy. These organizations work closely with industry experts, regulatory bodies, and other stakeholders to ensure that the developed standards meet specific needs.

    Standards Evolution and Update

    Standards governing ICH Q11: Impurity Control Strategy are subject to periodic review and update. This ensures that the standards remain relevant and effective in ensuring the quality of pharmaceutical products.

  • ISO 17025:2005 was revised to ISO/IEC 17025:2018 (General requirements for the competence of testing and calibration laboratories)

  • ASTM E2553-10 was revised to ASTM E2854-19 (Standard Guide for Impurities in Pharmaceuticals)

    • Specific Standard Numbers and Scope

    The following are specific standard numbers and their scope:

  • ISO/IEC 17025:2018 - General requirements for the competence of testing and calibration laboratories

  • ASTM E2553-10 (Revised to E2854-19) - Standard Guide for Impurities in Pharmaceuticals

  • EN 14636:2014 - Pharmaceuticals - Impurities in pharmaceutical substances

    • Standard Compliance Requirements

    Standard compliance requirements vary depending on the industry, sector, or regulatory requirement. The following are some examples of standard compliance requirements:

  • ISO/IEC 17025:2018 is required for testing and calibration laboratories.

  • ASTM E2854-19 is recommended for pharmaceutical manufacturers and suppliers.

  • EN 14636:2014 is mandatory for pharmaceutical companies operating in the European Union.

    • In this section, we will provide additional information about standard-related topics relevant to ICH Q11: Impurity Control Strategy.

    Why ICH Q11: Impurity Control Strategy is Required

    ICH Q11: Impurity Control Strategy is required for several reasons:

  • To ensure the quality and safety of pharmaceutical products.

  • To comply with regulatory requirements.

  • To maintain customer trust and confidence.

    • Business and Technical Reasons

    The business and technical reasons for conducting ICH Q11: Impurity Control Strategy testing are as follows:

  • To identify and control impurities in drug substances.

  • To ensure compliance with regulatory requirements.

  • To maintain product quality and safety.

  • To reduce the risk of product recall or contamination.

    • Consequences of Not Performing This Test

    The consequences of not performing ICH Q11: Impurity Control Strategy testing are as follows:

  • Regulatory non-compliance.

  • Product contamination or recall.

  • Loss of customer trust and confidence.

  • Financial losses due to product failure or regulatory penalties.

    • Impurities in Pharmaceuticals

    Impurities in pharmaceuticals can be categorized into two main types: organic and inorganic impurities. Organic impurities include compounds such as residues, degradation products, and solvents. Inorganic impurities include metals and metal ions.

    Identification and Control of Impurities

    The identification and control of impurities in drug substances are critical to ensuring product quality and safety. This can be achieved through various methods, including:

  • High-performance liquid chromatography (HPLC).

  • Gas chromatography (GC).

  • Mass spectrometry (MS).
