Bensley, Office of New Animal Drug Evaluation (HFV-140), Center for Veterinary Medicine, Food [[Page 53394]] and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301- 827-6956. SUPPLEMENTARY INFORMATION: I. Background Section 116 of the Food and Drug Administration Modernization Act (the Modernization Act) amended the Federal Food, Drug, and Cosmetic Act (the act) by adding section 506A (21 U.S.C. 356a). This section provides requirements for making and reporting manufacturing changes to an approved application and for distributing a drug product made with such change. Elsewhere in this issue of the Federal Register, FDA is proposing to amend its regulations on supplements and other changes to an approved application Sec. 514.8 (21 CFR 514.8) to conform to section 506A of the act. The purpose of this draft guidance is to provide recommendations to holders of NADA's and ANADA's who intend to make postapproval changes in accordance with section 506A of the act and the proposed amended regulations at Sec. 514.8. The draft guidance covers recommended reporting categories for postapproval changes for new animal drugs. Recommendations are provided for postapproval changes in: (1) Components and composition, (2) sites, (3) manufacturing process, (4) specification(s), (5) package, and (6) miscellaneous changes. This draft guidance does not provide recommendations on the specific information that should be developed by an applicant to validate the effect of the change on the identity, strength (e.g., assay, content uniformity), quality (e.g., physical, chemical, and biological properties), purity (e.g., impurities and degradation products), or potency (e.g., biological activity, bioavailability, bioequivalence) of a product as they may relate to the safety or effectiveness of the product. FDA has published guidances, including the Scale-up and Postapproval Changes (SUPAC) guidances, that provide recommendations on reporting categories and/or the type of information that should be developed by the applicant to validate the effect of the change on the identity, strength, quality, purity, or potency of a product as they may relate to the safety or effectiveness of the product. The draft guidance, which cites proposed Sec. 514.8, will be revised based on public comments and implemented for use as a companion document when Sec. 514.8 is finalized. This draft guidance represents the agency's current thinking on this subject. 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 requirement of the applicable statute, regulations, or both. II. Comment Interested persons may, on or before December 15, 1999, submit to the Dockets Management Branch (address above) written comments regarding the draft guidance. Two copies of any comments are to be submitted, except that individuals may submit one copy. Comments are to be identified with the docket number found in brackets in the heading of this document. A copy of the draft guidance and received comments may be seen in the office above between 9 a.m. and 4 p.m., Monday through Friday. III. Electronic Access Persons with access to the Internet may obtain the draft guidance using the World Wide Web (WWW). For WWW access, connect to CVM at ``http://www.fda.gov/cvm''. Dated: June 23, 1999.
