SUPPLEMENTARY INFORMATION:

I. Background

In recent years, many important initiatives have been undertaken by regulatory authorities and industry associations to promote the international harmonization of regulatory requirements. FDA has participated in efforts to enhance harmonization and has expressed its commitment to seek scientifically based harmonized technical procedures for the development of pharmaceutical products. One of the goals of harmonization is to identify and then reduce differences in technical requirements for drug development among regulatory agencies in different countries.

FDA has actively participated in the International Conference on Harmonization of Technical Requirements for Approval of Pharmaceuticals for Human Use for several years to develop harmonized technical requirements for the approval of human pharmaceutical and biological products among the European Union, Japan, and the United States. VICH is a parallel initiative for veterinary medicinal products. VICH is concerned with developing harmonized technical requirements for the approval of veterinary medicinal products in the European Union, Japan, and the United States, and includes input from both regulatory and industry representatives.

The VICH steering committee is composed of member representatives from the European Commission; European Medicines Evaluation Agency; European Federation of Animal Health; Committee on Veterinary Medicinal Products; FDA; the U.S. Department of Agriculture; the Animal Health Institute; the Japanese Veterinary Pharmaceutical Association; the Japanese Association of Veterinary Biologics; and the Japanese Ministry of Agriculture, Forestry, and Fisheries.

Four observers are eligible to participate in the VICH steering committee: One representative from the government of Australia/New Zealand, one representative from the industry in Australia/New Zealand, one representative from the government of Canada, and one representative from the industry of Canada. The VICH Secretariat, which coordinates the preparation of documentation, is provided by the International Federation for Animal Health (IFAH). An IFAH representative also participates in the VICH steering committee meetings.

II. Draft Revised Guidance on Impurities in New Veterinary Drug Substances

In May 2005, the VICH steering committee agreed that a draft revised guidance entitled “Impurities in New Veterinary Drug Substances (Revision)” VICH GL10(R) should be made available for public comment. The draft revised guidance is a revision of a final guidance on the same topic for which a notice of availability was published in the Federal Register of July 7, 2000 (65 FR 42020). The draft revised guidance clarifies the 2000 guidance, adds information, and provides consistency with more recently published VICH guidances. The draft revised guidance is the product of the Quality Expert Working Group of VICH. Comments about this draft will be considered by FDA and the Quality Expert Working Group.

This draft revised document is intended to provide guidance for registration applications on the content and qualification of impurities in new veterinary drug substances intended to be used for new veterinary medicinal products, produced by chemical syntheses and not previously registered in a country, region, or member state.

The draft revised guidance includes revised text on recommended threshold limits and revised text on recommended specification limits for impurities. Additions to the glossary include definitions for the terms “identification threshold” and “qualification threshold.” References to validated limits of quantitation were removed. In addition, minor editorial changes were made to improve the clarity and consistency of the document.

III. Paperwork Reduction Act of 1995

This draft revised guidance contains information collection provisions that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in this draft revised guidance have been approved under OMB control number 0910-0032.

IV. Significance of Guidance

This draft revised document, developed under the VICH process, has been revised to conform to FDA's good guidance practices regulation (21 CFR 10.115). For example, the document has been designated “guidance” rather than “guideline.” In addition, guidance documents must not include mandatory language such as “shall,” “must,” “required,” or “requirement,” unless FDA is using these words to describe a statutory or regulatory requirement.

The draft revised VICH guidance represents the agency's current thinking on impurities in new veterinary drug substances. This draft revised guidance does not create or confer any rights for or on any person and will not operate to bind FDA or the public. An alternative method may be used as long as it satisfies the requirements of applicable statutes and regulations.

V. Comments

This draft revised guidance document is being distributed for comment purposes only and is not intended for implementation at this time. Interested persons may submit to the Division of Dockets Management (see ADDRESSES) written or electronic comments regarding this draft revised guidance document. Submit a single copy of electronic comments or two paper copies of any mailed comments, except that individuals may submit one paper copy.
