[Docket No. 2007D-0168]

 
Draft Guidances for Industry Describing Product-Specific 
Bioequivalence Recommendations; Availability

AGENCY:  Food and Drug Administration, HHS.

ACTION:  Notice.

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

SUMMARY: This notice announces the availability of draft guidances for 
industry that describe recommendations on how to design bioequivalence 
(BE) studies for 200 specific drug products to support abbreviated new 
drug applications (ANDAs). These draft guidances are being made 
available

[[Page 30387]]

concurrently with the publication of a draft guidance for industry 
entitled ``Draft Guidance for Industry--Bioequivalence Recommendations 
for Specific Products'' (product specific BE recommendations). This 
draft guidance describes the new process for making available guidance 
on product-specific BE studies. Under the process described in the 
draft guidance, draft and final product-specific BE study guidance will 
be made available on the FDA Web site. FDA believes that making this 
information available on the Internet will streamline the guidance 
process and provide a meaningful opportunity for the public to consider 
and comment on product-specific BE study recommendations. Elsewhere in 
this issue of the Federal Register, FDA is announcing the availability 
of a related guidance document entitled ``Draft Guidance for Industry--
Bioequivalence Recommendations for Specific Products.''

DATES:  Submit written or electronic comments on the draft guidances by 
September 28, 2007. General comments on agency guidance documents are 
welcome at any time.

ADDRESSES:  Submit written requests for single copies of draft product-
specific BE study guidances to the Division of Drug Information (HFD-
240), Center for Drug Evaluation and Research, Food and Drug 
Administration, 5600 Fishers Lane, Rockville, MD 20857. Send one self-
addressed adhesive label to assist that office in processing your 
requests. Submit written comments on the draft guidance to the Division 
of Dockets Management (HFA-305), Food and Drug Administration, 5630 
Fishers Lane, rm. 1061, Rockville, MD 20852. Submit electronic comments 
to http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.fda.gov/dockets/ecomments. See the SUPPLEMENTARY 

INFORMATION section for electronic access to the draft guidance 
document.

FOR FURTHER INFORMATION CONTACT: Doan T. Nguyen, Center for Drug 
Evaluation and Research (HFD-600), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-0495.

SUPPLEMENTARY INFORMATION:

I. Background

    To receive approval for an ANDA, an applicant generally must 
demonstrate, among other things, that its product has the same active 
ingredient, dosage form, strength, route of administration and 
conditions of use as the listed drug, and that the proposed drug 
product is bioequivalent to the reference listed drug (21 U.S.C. 
355(j)(2)(A); 21 CFR 314.94(a)). Bioequivalent drug products show no 
significant difference in the rate and extent of absorption of the 
therapeutic ingredient (21 U.S.C. 355(j)(8); 21 CFR 320.1(e)). BE 
studies are undertaken in support of ANDA submissions with the goal of 
demonstrating BE between a proposed generic drug product and its 
reference listed drug. The regulations governing BE are provided at 21 
CFR in part 320.
    The draft guidance entitled ``Bioequivalence Recommendations for 
Specific Products'' describes the following process for making 
available draft and final product-specific BE recommendations:
     FDA will develop product-specific BE recommendations and 
post them on the Center for Drug Evaluation and Research (CDER) 
guidance page (http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.fda.gov/cder/index.html) in draft to 

facilitate public consideration and comment. The recommendations can be 
viewed by clicking on the URL associated with the ``Bioequivalence 
Recommendations for Specific Products'' guidance on the CDER guidance 
page or on the Office of Generic Drugs Page (see http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.fda.gov/cder/ogd/index.htm
). Users can also search for a specific product BE 

recommendation using the search tool on the CDER guidance page.
     Newly posted draft and final BE recommendations will be 
announced in the ``Newly Added Guidance Documents'' list, which is 
posted monthly on the CDER guidance page.
     The agency will issue a notice in the Federal Register 
announcing the availability on the FDA web site of new product-specific 
draft and final BE recommendations. The notice will identify a comment 
period for the recommendations.
     Comments on product-specific BE recommendations will be 
considered in developing final BE recommendations.
     The BE recommendations will be revised as appropriate to 
ensure that the most up-to-date BE information is available to the 
public.
    FDA is making the first group of draft product-specific BE 
recommendations available concurrently with the issuance of the draft 
guidance document describing the process.
