SUPPLEMENTARY INFORMATION: I. Background In the Regulatory Science Enhancements section of the GDUFA Reauthorization Performance Goals and Program Enhancement Fiscal Years 2018-2022 (GDUFA II Commitment Letter) (available at: https://www.fda.gov/downloads/ForIndustry/UserFees/GenericDrugUserFees/UCM525234.pdf) FDA committed to ``conduct internal and external research to support fulfilment of submission review and pre-ANDA commitments.'' This continues commitments made in the GDUFA Program Performance Goals and Procedures for fiscal years 2013 through 2017 (GDUFA I Commitment Letter) (available at: https://www.fda.gov/downloads/ForIndustry/UserFees/GenericDrugUserFees/UCM282505.pdf). For complex OINDPs, this research is intended to support the development of scientific guidance and Agency policy to clarify the ANDA pathway for OINDPs and aid our understanding about the critical product attributes relevant for in vivo performance of OINDPs. This work has led to the development of tools beneficial to both industry and FDA for developing and evaluating generic OINDPs. This regulatory science research includes, but is not limited to, the following: (1) Identification of critical formulation and device attributes of generic OINDPs; (2) development of clinically relevant in vitro tools for prediction of in vivo regional drug deposition and dissolution from OINDPs; (3) development of computational fluid dynamic (CFD) and physiologically- based pharmacokinetic (PBPK) models for prediction of the local and systemic exposure of drugs delivered through OINDPs and to assess their applicability in generic OINDP development programs; and (4) identification, validation, and standardization of novel techniques that can be used for future bioequivalence assessments for generic OINDPs. Since its commencement in 2012, the GDUFA Regulatory Science Research Program has continuously aided our understanding about the critical product attributes that are relevant for in vivo performance of OINDPs, and has led to the development of tools beneficial to both industry and FDA for developing and assessing generic OINDPs. Several external and internal research projects have been initiated under the GDUFA Regulatory Science Research Program. The outcomes from these research studies have provided valuable insight about the factors influencing the performance of OINDPs and have helped the Agency fill regulatory science gaps in this area. For instance, advanced modeling tools developed under this initiative, such as CFD and PBPK, can provide insights about patient-device interactions and information about both local and systemic bioavailability, which can better characterize critical device and formulation attributes to further our understanding of generic drug-device combination products. Clinically relevant mouth-throat and nasal models are another example of this research which have shown good in vivo correlations in predicting regional drug deposition; these physical models allow us to predict the impact of certain performance characteristics of OINDPs on regional drug deposition in a realistic manner, potentially without the need for conducting comparative clinical endpoint studies. Similarly, Morphologically Directed Raman Spectroscopy (MDRS), a novel particle sizing method explored under the initiative, has shown promise in differentiating nasal suspension formulations of different drug particle sizes, and has opened the possibility of a new regulatory pathway for the approval of generic nasal suspension products without the need to conduct a comparative clinical endpoint study. Another research outcome developed under the science initiative for OINDPs has been work involving in-vitro dissolution methods, which are providing insights on the bridge between local drug deposition and its downstream systemic bioavailability. Our enhanced understanding about OINDPs from these regulatory science-based initiatives have informed us during the development of product-specific guidances for OINDPs, resulting in the publication of more than 39 product-specific guidance documents since the implementation of GDUFA in 2012. To enhance communication of recent advances, including those supported by GDUFA funds, FDA plans to hold a public workshop on new analytical methods and assessment criteria for characterization of OINDPs. II. Purpose and Scope of the Workshop The purposes of the workshop are as follows: 1. To present the outcomes from the research projects initiated under the GDUFA Regulatory Science Research Program; 2. To discuss how regulatory science initiatives have helped address regulatory science gaps by providing insight on factors that influence the performance of OINDPs; 3. To share the Agency's experience on the utility of novel analytical tools and methods developed under the regulatory science initiative for OINDP product development and bioequivalence assessments; and 4. To obtain input from the public on what, when, where, and how analytical methods and procedures should be applied in the development and review of complex OINDP ANDAs for therapeutic equivalence. The scope of the workshop covers the current status of methods for characterization and bioequivalence evaluation of generic OINDPs. The focus of this public workshop is on the evaluation of these new methods for characterizing and demonstrating therapeutic equivalence of OINDPs, including discussing the areas in which these methods may significantly contribute to generic product development and regulatory understanding, how and under what conditions the methods should be conducted and evaluated, and inherent scientific challenges with this complex class of products. Public input will improve FDA's current understanding of present and future methods available for evaluating OINDP therapeutic equivalence. The knowledge gained through this workshop discussion will be summarized and disseminated to the scientific community by publication(s). III. Scope of Public Input Requested FDA seeks input from the public on when, where, and how to utilize new methods for development of generic OINDPs and in the regulatory review of bioequivalence. Specific topics to be addressed include: 1. Identifying the areas in which new in vitro and computational methods can contribute to the development of generic OINDPs; 2. Discussing how in vitro testing for demonstrating OINDP therapeutic equivalence should be conducted and evaluated; and 3. Addressing the scientific challenges in assessing critical quality attributes of OINDPs and in developing new [[Page 60203]] methods for demonstrating OINDP therapeutic equivalence.
