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

methods for demonstrating OINDP therapeutic equivalence.
