Nonclinical Safety Evaluation of Reformulated Drug Products and 
Products Intended for Administration by an Alternate Route; Guidance 
for Industry and Review Staff; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

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

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a guidance for industry and review staff entitled 
``Nonclinical Safety Evaluation of Reformulated Drug Products and 
Products Intended for Administration by an Alternate Route.'' The 
guidance provides recommendations concerning the evaluation of the 
nonclinical safety of reformulated drug products or products being used 
by an alternate route. It is intended for use by interested individuals 
in industry and reviewers within the Center for Drug Evaluation and 
Research (CDER). The goals of this guidance are to foster and expedite 
the development of reformulated drug products or the use of previously 
approved drugs by alternate routes, communicate to industry current 
CDER thoughts pertaining to safety data needed to support these drug 
products, and increase uniformity within CDER on expectations for the 
nonclinical development of reformulated drug products or products being 
used by an alternate route. This guidance finalizes the draft guidance 
of the same name published on March 7, 2008.

DATES: Submit either electronic or written comments on Agency guidances 
at any time.

ADDRESSES: You may submit comments as follows:

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry and 
review staff entitled ``Nonclinical Safety Evaluation of Reformulated 
Drug Products and Products Intended for Administration by an Alternate 
Route.'' This guidance provides recommendations regarding the 
nonclinical evaluation of a new formulation containing a previously 
approved drug substance and of a product proposed for use by an 
alternate route of administration for which the product was not 
previously approved.
    Generally, nonclinical data support use of a drug product by a 
particular route and also reflect the planned duration of use. Much of 
the available nonclinical information used to support approval of the 
initial formulation can be used to support the safety of additional 
formulations assuming all legal rights to the information are met. 
Information used to support an initial formulation, however, may not 
always be sufficient to support such additional approvals because 
changes in the formulation could produce a new toxicity. This is 
particularly true if the drug product's route of administration is 
different or the duration of use changes markedly. Therefore, 
additional nonclinical studies might be recommended to ensure that the 
toxicity of a new formulation is fully characterized.
    This guidance provides general nonclinical considerations for all 
reformulations or new routes of use and several route-specific 
considerations. The considerations in this guidance can also be applied 
to routes not specifically mentioned in the guidance.
    This guidance finalizes the draft guidance of the same name 
published on March 7, 2008. Changes to the guidance include the 
addition of a recommendation that toxicology studies be conducted under 
good laboratory practices, clarification that histopathology can be 
limited in some cases to locally exposed tissues, the addition of a 
reference to the International Conference on Harmonisation guidance for 
industry entitled ``S10 Photosafety Evaluation of Pharmaceuticals,'' 
and other clarifications to the studies recommended for specific routes 
such as dermal, ocular, and intranasal.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on nonclinical safety evaluation of 
reformulated drug products and products intended for administration by 
an alternate route. 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.
