International Cooperation on Harmonisation of Technical 
Requirements for Registration of Veterinary Medicinal Products; 
Guidance for Industry on Studies To Evaluate the Metabolism and Residue 
Kinetics of Veterinary Drugs in Food-Producing Animals: Comparative 
Metabolism Studies in Laboratory Animals; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a guidance for industry (206) entitled 
``Guidance for Industry on Studies to Evaluate the Metabolism and 
Residue Kinetics of Veterinary Drugs in Food-Producing Animals: 
Comparative Metabolism Studies in Laboratory Animals'' (VICH GL47). 
This guidance has been developed for veterinary use by the 
International Cooperation on Harmonisation of Technical Requirements 
for Registration of Veterinary Medicinal Products (VICH). This VICH 
guidance document is intended to provide recommendations for 
internationally harmonized procedures to identify the metabolites of 
veterinary drugs produced by laboratory animals used for toxicological 
testing for the purpose of comparison to the residues of veterinary 
drugs in edible tissues of food-producing animals.

DATES: Submit either electronic or written comments on Agency guidances 
at any time.

ADDRESSES: Submit written requests for single copies of the guidance to 
the Communications Staff (HFV-12), Center for Veterinary Medicine, Food 
and Drug Administration, 7519 Standish Pl., Rockville, MD 20855. Send 
one self-addressed adhesive label to assist that office in processing 
your request. See the SUPPLEMENTARY INFORMATION section for electronic 
access to the guidance document.
    Submit electronic comments on the guidance to https://www.regulations.gov. Submit written comments to the Division of Dockets 
Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, 
Rm. 1061, Rockville, MD 20852.

FOR FURTHER INFORMATION CONTACT: Julia Oriani, Center for Veterinary 
Medicine (HFV-151), Food and Drug Administration, 7500 Standish Pl.,

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a guidance for industry 
(206) entitled ``Guidance for Industry on Studies to Evaluate 
the Metabolism and Residue Kinetics of Veterinary Drugs in Food-
Producing Animals: Comparative Metabolism Studies in Laboratory 
Animals'' (VICH GL47). 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 
Harmonisation 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. The 
VICH is a parallel initiative for veterinary medicinal products. The 
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, the U.S. 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

[[Page 57058]]

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. Guidance on Comparative Metabolism Studies in Laboratory Animals

    In the Federal Register of April 12, 2010 (75 FR 18507), FDA 
published a notice of availability for a draft guidance entitled 
``Draft Guidance for Industry on Studies to Evaluate the Metabolism and 
Residue Kinetics of Veterinary Drugs in Food-Producing Animals: 
Comparative Metabolism Studies in Laboratory Animals (VICH GL47),'' 
which gave interested persons until May 12, 2010, to comment on the 
draft guidance. FDA received a few comments on the draft guidance and 
those comments as well as those received by other VICH member 
regulatory agencies were considered as the guidance was finalized. At a 
meeting held in February 2011, the VICH Steering Committee endorsed the 
final guidance for industry (VICH GL47). The guidance announced in this 
notice finalizes the draft guidance dated April 12, 2010.
    This VICH guidance document is one of a series developed to 
facilitate the mutual acceptance by national/regional regulators of 
residue chemistry data for veterinary drugs used in food-producing 
animals. This guidance was prepared after consideration of the current 
national/regional requirements and recommendations for evaluating 
veterinary drug residues in the European Union, Japan, the United 
States, Australia, New Zealand, and Canada.
    The objective of this guidance is to provide recommendations for 
internationally harmonized procedures to identify the metabolites of 
veterinary drugs produced by laboratory animals. The purpose of the 
comparative metabolism studies is to compare the metabolites of the 
animals used for toxicological testing to the residues of the 
veterinary drugs in edible tissues of food-producing animals in order 
to determine if the laboratory animals used for toxicological testing 
have been exposed to the metabolites that humans can be exposed to as 
residues in products of food-producing animal origin.
    The human food safety evaluation of veterinary drug residues helps 
ensure that food derived from treated food-producing animals is safe 
for human consumption. As part of the data collection process, studies 
should be conducted to characterize the metabolites to which laboratory 
animals are auto-exposed during the toxicological testing of the 
veterinary drug. The purpose of these studies is to determine whether 
the metabolites that people will consume from tissues of target food-
producing animals are also produced by metabolism in the laboratory 
animals used for the safety testing.

III. Significance of Guidance

    This guidance, 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,'' ``require,'' or 
``requirement,'' unless FDA is using these words to describe a 
statutory or regulatory requirement.
    This guidance represents the Agency's current thinking on this 
topic. It does not create or confer any rights for or on any person and 
does not operate to bind FDA or the public. An alternative approach may 
be used if such approach satisfies the requirements of the applicable 
statutes and regulations.

IV. Paperwork Reduction Act of 1995

    This guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
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 guidance have been approved under 
OMB control number 0910-0032.

V. Comments

    Interested persons may submit to the Division of Dockets Management 
(see ADDRESSES) either electronic or written comments regarding this 
document. It is only necessary to send one set of comments. It is no 
longer necessary to send two copies of mailed comments. Identify 
comments with the docket number found in brackets in the heading of 
this document. Received comments may be seen in the Division of Dockets 
Management between 9 a.m. and 4 p.m., Monday through Friday.
