SUPPLEMENTARY INFORMATION: In compliance with 44 U.S.C. 3507, FDA has 
submitted the following proposed collection of information to OMB for 
review and clearance.

Waiver of In Vivo Demonstration of Bioequivalence of Animal Drugs in 
Soluble Powder Oral Dosage Form Products and Type A Medicated 
Articles--21 CFR 514.1(b)(7) and (b)(8) (OMB Control Number 0910-
0575)--Extension

    The Center for Veterinary Medicine has written this guidance to 
address a perceived need for Agency guidance in its work with the 
animal health industry. This guidance describes the procedures that the 
Agency recommends for the review of requests for waiver of in vivo 
demonstration of bioequivalence for generic soluble powder oral dosage 
form products and Type A medicated articles.
    The Generic Animal Drug and Patent Term Registration Act of 1988 
(Pub. L. 100-670) permitted generic drug manufacturers to copy those 
pioneer drug products that were no longer subject to patent or other 
marketing exclusivity protection. The approval for marketing these 
generic products is based, in part, upon a demonstration of 
bioequivalence between the generic product and pioneer product. This 
guidance clarifies circumstances under which FDA believes the 
demonstration of bioequivalence required by the statute does not need 
to be established on the basis of in vivo studies for soluble powder 
oral dosage form products and Type A medicated articles. The data 
submitted in support of the waiver request are necessary to validate 
the waiver decision. The requirement to establish bioequivalence 
through in vivo studies (blood level bioequivalence or clinical 
endpoint bioequivalence) may be waived for soluble powder oral dosage 
form products or Type A medicated articles in either of two alternative 
ways. A biowaiver may be granted if it can be shown that the generic 
soluble powder oral dosage form product or Type A medicated article 
contains the same active and inactive

[[Page 15765]]

ingredient(s) and is produced using the same manufacturing processes as 
the approved comparator product or article. Alternatively, a biowaiver 
may be granted without direct comparison to the pioneer product's 
formulation and manufacturing process if it can be shown that the 
active pharmaceutical ingredient(s) (API) is the same as the pioneer 
product, is soluble, and that there are no ingredients in the 
formulation likely to cause adverse pharmacologic effects. For the 
purpose of evaluating soluble powder oral dosage form products and Type 
A medicated articles, solubility can be demonstrated in one of two 
ways: ``USP definition'' approach or ``Dosage adjusted'' approach. The 
respondents for this collection of information are pharmaceutical 
companies manufacturing animal drugs. FDA estimates the burden for this 
collection of information as follows in tables 1 and 2 of this 
document. The source of the above data is records of generic drug 
applications over the past 10 years.
    In the Federal Register of October 24, 2011 (76 FR 65733), FDA 
published a 60-day notice requesting public comment on the proposed 
collection of information. FDA received one comment, which, however, 
did not address the questions posed in 60-day notice regarding the 
collection of information. The comment supported the bioequivalence 
program but suggested a revision to the determination of 
bioequivalence, which relates to the substance of the scientific 
recommendations in the guidance document. Under FDA's good guidance 
practices regulations (21 CFR 10.115(f)(4)), the public may suggest at 
anytime that FDA revise a guidance document and under 21 CFR 
10.115(g)(5), FDA will revise guidance documents in response to 
comments when appropriate.
    FDA estimates the burden of this collection of information as 
follows:
