2021-14202. Assessment of Adhesion for Topical and Transdermal Systems Submitted in New Drug Applications; Draft Guidance for Industry; Availability
-
Start Preamble
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The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Assessment of Adhesion for Topical and Transdermal Systems Submitted in New Drug Applications.” Transdermal delivery systems are designed to deliver a drug across the skin and into systemic circulation, whereas topical delivery systems are designed to deliver the drug to local tissue. There is pharmaceutical and other stakeholder interest in the development of new transdermal and topical products, and this guidance provides recommendations on the clinical assessment of adhesion for such products that will be submitted as new drug applications (NDAs) or supplemental new drug applications. This guidance provides additional study design and methodology recommendations on conducting in vivo adhesion studies. This guidance takes these developments into consideration. When final, this draft guidance will expand upon the recommendation for in vivo adhesion studies in section V., Special Topics, subsection A., Product Adhesion Considerations, in the draft guidance for industry Transdermal and Topical Delivery Systems—Product Development and Quality Considerations issued on November 21, 2019.
DATES:
Submit either electronic or written comments on the draft guidance by August 31, 2021 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.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:

I. Background
FDA is announcing the availability of a draft guidance for industry entitled “Assessment of Adhesion for Topical and Transdermal Systems Submitted in New Drug Applications.” This draft guidance provides recommendations on the clinical assessment of the adhesive properties of topical and transdermal delivery systems (collectively referred to as TDS) intended for submission in an NDA or supplemental NDA. The amount of drug delivered into and through the patient's skin from a TDS is dependent, in part, on the ability of the TDS to remain in direct contact with the skin (adhesive properties). Adhesive properties are clinically important as a loss of TDS adhesion during wear can reduce the amount of drug delivered to the patient, potentially compromising effectiveness. Additionally, partial or full detachment of a TDS from a patient's skin may result in unintentional exposure of the drug to others, potentially compromising safety. This draft guidance includes key considerations for the design of the TDS adhesion clinical study, including the selection of endpoints and FDA's current thinking on acceptable adhesion performance in the in vivo setting.
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 “Assessment of Adhesion for Topical and Transdermal Systems Submitted in New Drug Applications” and will supersede in vivo recommendations in section V., Special Topics in the draft guidance for industry “Transdermal and Topical Delivery Systems—Product Development and Quality Considerations” issued on November 21, 2019 (84 FR 64319). 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.
II. Paperwork Reduction Act of 1995
While this guidance contains no collection of information, it does refer to previously approved FDA collections of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not required for this guidance. The previously approved collections of information are subject to review by OMB under the PRA. The collections of information in 21 CFR part 314 have been approved under OMB control number 0910-0001, and the collections of information for the electronic submission of drug establishment registration and drug listing information have been approved under OMB control number 0910-0045.
III. Electronic Access
Persons with access to the internet may obtain the draft guidance at either https://www.fda.gov/drugs/guidance-compliance-regulatory-information/guidances-drugs or https://www.regulations.gov.
