Assessing the Irritation and Sensitization Potential of Transdermal and Topical Delivery Systems for Abbreviated New Drug Applications; Draft Guidance for Industry; Availability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The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled "Assessing the Irritation and Sensitization Potential of Transdermal and Topical Delivery Systems for ANDAs." This draft guidance provides recommendations for the design and conduct of studies to evaluate the in vivo skin irritation and sensitization (I/S) potential of a proposed transdermal or topical delivery system (collectively referred to as TDS). The recommendations in this draft guidance relate exclusively to studies submitted in support of an abbreviated new drug application (ANDA).

DATES:

Submit either electronic or written comments on the draft guidance by December 10, 2018 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

ADDRESSES:

You may submit comments on any guidance at any time as follows:

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled "Assessing the Irritation and Sensitization Potential of Transdermal and Topical Delivery Systems for ANDAs."

The components and composition of a TDS formulation, including the nature of the drug substance and/or the occlusivity of the TDS materials, in conjunction with other factors such as the environmental humidity or the condition of the skin, may have the potential to irritate the skin or lead to a sensitization reaction. Such reactions can be unpleasant to the patient and may affect patient compliance, skin permeability, and/or adhesion of the TDS to the skin. The collective consequence of these potential effects could create uncertainty about the resulting drug delivery profile and uncertainty about the rate and extent of drug absorption from the TDS. Therefore, applicants should perform a comparative assessment of the test (T) and reference (R) TDS products using an appropriately designed skin I/S study with human subjects to demonstrate that the potential for a skin irritation or sensitization reaction with the T TDS is no worse than the reaction observed with the R TDS.

This draft guidance provides recommendations for the design and conduct of studies to evaluate the in vivo skin I/S potential of a proposed TDS. The recommendations in this draft guidance relate exclusively to studies submitted in support of an ANDA.

The Agency is seeking comments on the recommendations reflected in the draft guidance announced in this notice. In addition, FDA invites comments on the scales and any alternative approaches, including those recommended by international regulatory agencies, that may have been used with success for the comparative assessment of the I/S potential for proposed generic TDS products. FDA also specifically invites comments regarding the comparative assessment of sensitization itself, i.e., whether there are clinical scenarios where a comparative sensitization assessment may be uninformative when done in addition to a comparative irritation assessment.

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 current thinking of FDA on "Assessing the Irritation and Sensitization Potential of Transdermal and Topical Delivery Systems for ANDAs." 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.
