Design Considerations of Generic Dermatological Products

Design Considerations of Generic Dermatological Products

Lakshmi Raghavan, Ph.D. (Solaris Pharma Corporation)



The Food and Drug Administration’s (FDA) approach to approving any generic drug product is based on the Abbreviated New Drug Application (ANDA) providing enough scientific justification to prove it is bioequivalent to the approved Reference Product. For topically administered drugs, the standard approach has been to conduct a clinical end-point study with a pharmaceutically equivalent product and prove therapeutic equivalence with the Reference Product. The pharmaceutical equivalence is established through demonstration of qualitative (Q1) and quantitative (Q2) sameness as well as establishing microstructural arrangement of matter sameness (Q3). Systematic science and risk-based approaches using Quality by Design (QbD) principles are utilized to identify the critical quality attributes (CQA), critical material attributes (CMA) and critical process parameters (CPP) and guide control strategies in developing a quality generic dermatological product. Demonstrating bioequivalence of a pharmaceutically equivalent product through clinical end point studies is extremely complex and expensive due to the lack of sensitivity in detecting differences between the test and the reference product. In vitro Release (IVRT) and skin permeation tests (IVPT) can be used as surrogate tool to predict in vivo performance in human clinical end-point studies. This talk will address some of the design considerations that will be critical in developing a bioequivalent
generic topical product.
