The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry titled "Assessing Adhesion With Transdermal and Topical Delivery Systems for ANDAs." This guidance provides recommendations for the design and conduct of studies evaluating the adhesion performance of a transdermal or topical delivery system (collectively referred to as TDS). Depending on the objectives of a generic TDS product development program, applicants may choose to evaluate TDS adhesion in studies performed to evaluate TDS adhesion only, or in studies performed with a combined purpose (e.g., for the simultaneous evaluation of adhesion and bioequivalence (BE) with pharmacokinetic (PK) endpoints). The recommendations in this guidance relate to studies submitted in support of an abbreviated new drug application (ANDA). The guidance replaces the draft guidance (Revision 2) "Assessing Adhesion With Transdermal and Topical Delivery Systems for ANDAs," issued on April 13, 2023.
