SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft GFI #171 entitled 
``Demonstrating Bioequivalence for Soluble Powder Oral Dosage Form 
Products and Type A Medicated Articles Manufactured from Active 
Pharmaceutical Ingredients Considered to be Soluble in Aqueous Media.'' 
This draft guidance describes how the Agency intends to evaluate 
requests for waiving the requirement for performing in vivo 
bioequivalence studies (biowaivers) for animal drugs administered 
orally as soluble powders or as Type A medicated articles manufactured 
from active pharmaceutical ingredients (APIs) considered to be soluble 
in aqueous media (water soluble APIs). This draft guidance expands upon 
GFI #35, ``Bioequivalence Guidance,'' published November 8, 2006, to 
include biowaivers for soluble powder oral dosage form products as well 
as Type A medicated articles manufactured from active pharmaceutical 
ingredients considered to be soluble in aqueous media. This draft 
guidance offers particular focus on criteria for the waiver of the 
requirements for

[[Page 51597]]

submitting in vivo bioequivalence study data.
    This draft guidance is applicable to generic investigational new 
animal drug (JINAD) files and to abbreviated new animal drug 
applications (ANADAs). Although the recommendations in this guidance 
refer to generic drug applications, the general principles described 
may also be applicable to new animal drug applications (NADAs), 
investigational new animal drug (INAD) files, and supplemental NADAs. 
This draft guidance does not address Type A medicated articles 
manufactured from active pharmaceutical ingredients considered to be 
insoluble in aqueous media.

II. Significance of Guidance

    This level 1 draft guidance is being issued consistent with FDA's 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 The draft guidance, 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 
``Demonstrating Bioequivalence for Soluble Powder Oral Dosage Form 
Products and Type A Medicated Articles Manufactured from Active 
Pharmaceutical Ingredients Considered to be Soluble in Aqueous Media.'' 
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. This 
guidance is not subject to Executive Order 12866.

III. Paperwork Reduction Act of 1995

    This draft guidance refers to collections of information associated 
with biowaiver requests for generic soluble powder oral dosage form 
products and Type A medicated articles. 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 associated with biowaiver 
requests for generic soluble powder oral dosage form products and Type 
A medicated articles are being reviewed by OMB under OMB control number 
0910-0669 (see 84 FR 16270 at 16271, April 18, 2019).
