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

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a draft guidance for industry entitled ``New Chemical 
Entity Exclusivity Determinations for Certain Fixed-Combination Drug 
Products.'' This draft guidance sets forth a change in the Agency's 
interpretation of the 5-year new chemical entity (NCE)

exclusivity statutory and regulatory provisions as they apply to 
certain fixed-combination drug products (fixed combinations). If the 
guidance is finalized, a drug product will be eligible for 5-year NCE 
exclusivity if it contains a drug substance that meets the definition 
of ``new chemical entity,'' regardless of whether that drug substance 
is approved alone or in certain fixed-combinations.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by April 25, 2014.

ADDRESSES: Submit written requests for single copies of the draft 
guidance to the Division of Drug Information, Center for Drug 
Evaluation and Research, Food and Drug Administration, 10903 New 
Hampshire Ave., Bldg. 51, Rm. 2201, Silver Spring, MD 20993-0002. Send 
one self-addressed adhesive label to assist that office in processing 
your requests. See the SUPPLEMENTARY INFORMATION section for electronic 
access to the draft guidance document.
    Submit electronic comments on the draft guidance to http://www.regulations.gov. Submit written comments to the Division of Dockets 
Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane,

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``New Chemical Entity Exclusivity Determinations for Certain 
Fixed-Combination Drug Products.'' This guidance sets forth a change in 
the Agency's interpretation of the 5-year NCE exclusivity provisions as 
they apply to certain fixed-combinations. Sections 505(c)(3)(E)(ii) and 
(j)(5)(F)(ii) of the Food, Drug, and Cosmetic Act and 21 CFR 314.108, 
among other provisions, establish the scheme under which a drug product 
is eligible for 5-year NCE exclusivity. The Agency currently interprets 
the term ``drug'' as it appears in the first subclause of the statutory 
provisions and in the definition of ``new chemical entity'' in its 
regulation to mean ``drug product.'' This results in a fixed-
combination not being eligible for 5-year NCE exclusivity if it 
contains any drug substance that contains an active moiety that had 
been previously approved by the Agency, even if the fixed-combination 
also contains another drug substance that contains a previously 
unapproved active moiety.
    The Agency recognizes, however, that fixed-combinations have become 
increasingly prevalent in certain therapeutic areas and that these 
products play an important role in optimizing adherence to dosing 
regimens and improving patient outcomes. Therefore, to further 
incentivize the development of fixed-combinations containing previously 
unapproved active moieties, the Agency is revising its existing 
interpretation regarding the eligibility for 5-year NCE exclusivity of 
certain fixed-combinations. Under the revised interpretation, the term 
``drug'' in the relevant provisions would be interpreted to mean ``drug 
substance'' or ``active ingredient,'' and not ``drug product.'' 
Accordingly, a drug product would be eligible for 5-year NCE 
exclusivity provided that it contains any drug substance that contains 
no active moiety that has been previously approved. This will permit a 
drug substance that meets the definition of new chemical entity (i.e., 
it contains no previously approved active moiety) to be eligible for 5-
year NCE exclusivity, even when it is approved in a fixed-combination 
with another drug substance that contains a previously approved active 
moiety.
    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 Agency's current thinking on 5-year NCE 
exclusivity for certain fixed-combinations. 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 requirements of the applicable statutes and regulations.
