# SUPPLEMENTARY INFORMATION:

## I. Background

                    FDA is announcing the availability of a draft GFI #100 (VICH GL18(R2)) entitled “Impurities: Residual Solvents in New Veterinary Medicinal Products, Active Substances and Excipients (Revision 2).” Residual solvents in pharmaceuticals are defined in the guidance as organic volatile chemicals that are used or produced in the manufacture of active substances or                           ( print page 42729)                        excipients, or in the preparation of veterinary medicinal products. The solvents are not completely removed by practical manufacturing techniques. The objective of this draft guidance is to recommend acceptable amounts for residual solvents in pharmaceuticals for the safety of the target animal as well as for the safety of residues in products derived from treated food-producing animals. The draft guidance recommends use of less toxic solvents and describes levels considered to be toxicologically acceptable for some residual solvents. This revision updates the listings and classification of solvents.                

FDA has participated in efforts to enhance harmonization and is committed to seeking scientifically based harmonized technical procedures for pharmaceutical development. 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 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 and European Medicines Agency; International Federation for Animal Health—Europe; FDA—Center for Veterinary Medicine and U.S. Department of Agriculture—Center for Veterinary Biologics; the U.S. Animal Health Institute; the Japanese Veterinary Products Association, and the Japanese Ministry of Agriculture, Forestry, and Fisheries.

There are eight observers to the VICH Steering Committee: One representative from government and one representative from industry of Australia, New Zealand, Canada, and South Africa. The World Organisation for Animal Health is an associate member of the VICH. The VICH Secretariat, which coordinates the preparation of documentation, is provided by the International Federation of Animal Health.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Impurities: Residual Solvents in New Veterinary Medicinal Products, Active Substances and Excipients (Revision 2).” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

## II. Paperwork Reduction Act of 1995

While this draft guidance contains no collection of information, it does refer to previously approved FDA collections of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not required for this guidance. The previously approved collections of information are subject to review by OMB under the PRA. The collections of information in section 512(n)(1) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(n)(1)) have been approved under OMB control number 0910-0669; the collections of information in 21 CFR part 514 have been approved under OMB control number 0910-0032.

## III. Electronic Access

                    Persons with access to the internet may obtain an electronic version of the draft guidance at                     *https://www.fda.gov/​animal-veterinary/​guidance-regulations/​guidance-industry, https://www.fda.gov/​regulatory-information/​search-fda-guidance-documents,*                     or                     *https://www.regulations.gov*.
