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 This guidance finalizes the draft guidance of the same name published on March 7, 2008.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:

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.
