[Docket No. FDA-2017-N-5442]


Leveraging Quantitative Methods and Modeling To Modernize Generic 
Drug Development and Review; Public Workshop; Request for Comments

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of public workshop; request for comments.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA, the Agency, or we) is 
announcing the following public workshop entitled ``Leveraging 
Quantitative Methods and Modeling to Modernize Generic Drug Development 
and Review.'' The purpose of the public workshop is to engage 
stakeholders in a discussion of current and emerging scientific 
approaches and applications for the conduct of quantitative modeling 
and simulations in generic drug development, especially for complex and 
locally acting products, and to gain input regarding opportunities and 
knowledge gaps related to the use of quantitative modeling and 
simulation to inform regulatory decision making through the product 
lifecycle. FDA will use the information gained through the workshop to 
support product-specific guidance development, improve pre-abbreviated 
new drug applications (ANDA) interactions with applicants, increase the 
quality and efficiency of regulatory reviews, and identify a next 
generation modeling and simulation toolset for complex and locally 
acting products.

SUPPLEMENTARY INFORMATION:

I. Background

    To enhance dialogue regarding modeling and simulation and 
communication of recent advances in modeling and simulation, including 
those supported by the Generic Drug User Fee Amendments regulatory 
science research program, FDA plans to hold a public workshop to (1) 
engage stakeholders in a discussion of current and emerging scientific 
approaches and applications for the conduct of quantitative modeling 
and simulations in generic drug development, especially for complex and 
locally acting products, and (2) gain input regarding opportunities and 
knowledge gaps related to the use of quantitative modeling and 
simulation to inform regulatory decision making through the product 
lifecycle.
    Modeling and simulation has been increasingly used in drug 
development, providing a framework for synthesizing information and 
extrapolating beyond what has been studied. Model-informed drug 
development (MIDD) approaches can be applied to brand drug products 
approved pursuant to a new drug application (NDA), and generic drug 
products approved pursuant to an ANDA. MIDD holds particular promise in 
key opportunity areas including pharmacokinetic/pharmacodynamics (PK/
PD) models, physiologically based pharmacokinetic (PBPK) or absorption 
models, systems pharmacology, quantitative risk modeling, and emergent 
machine learning tools. These application areas can leverage the large 
pharmaceutical data sets (big data) available to FDA and other 
organizations. Quantitative approaches have been used to address 
significant scientific and regulatory issues in all phases of the 
product lifecycle: from pre-investigational new drug applications 
through NDAs, ANDAs, and post-approval evaluation of new and generic 
drugs. Given the broad applications of modeling and simulation through 
the entire lifecycle of a product, there is a need to identify best 
practices to improve the routine use and acceptance of modeling and 
simulation for regulatory decision making.
    The purposes of the workshop are to:
    (1) Engage global stakeholders and share experience and vision on 
using quantitative approaches in regulatory decision making for generic 
drug development and product lifecycle management;
    (2) Identify and prioritize potential areas for global 
harmonization for tools to inform regulatory decision making;
    (3) Share the current state of knowledge and practice in utilizing 
quantitative methods and modeling for generic drug development and 
review by case demonstrations and by integrating experience and lessons 
learned from new drug product development and reviews;
    (4) Identify opportunities for complex and locally acting product 
development and discuss approaches and principles in using quantitative 
methods and modeling to aid product-specific guidance development, pre-
ANDA interactions between FDA and prospective applicants, ANDA reviews, 
and postmarket performance monitoring; and
    (5) Discuss next generation quantitative method and modeling 
toolsets, future directions, and application areas beyond currently 
available tools.
    There is a paradigm shift to a risk-based product-specific 
regulatory approach for generic drugs. Examples of this transition 
include recommendations for partial AUC (area under the concentration-
time curve) for some modified release drugs and replicate study 
bioequivalence (BE) recommendations for narrow therapeutic index (NTI) 
drugs. These product-specific guidances are driven by the therapeutic 
significance of either the exposure-response relationships for safety 
and efficacy (NTI drugs) or the difference in the shape of PK profiles. 
Modeling and simulation toolsets direct the design and evaluation of PK 
or comparative clinical endpoint BE studies, help evaluate clinical 
endpoint sensitivity and feasibility, and enable the assessment of 
alternative BE approaches. Overall, quantitative methods and modeling 
support better and faster decisions during the generic drug development 
and review process because they integrate knowledge accumulated during 
and after new drug product development, including in vitro in vivo 
correlation for formulation design, absorption, distribution, 
metabolism, and excretion properties, population PK, and exposure-
response relationships for efficacy and safety.
    There is also a growing recognition that analysis of large datasets 
helps organizations and individuals make better decisions. Emerging 
methodologies that enable the Agency to take advantage of big data will 
impact how generic drugs are developed, reviewed, and monitored. 
Knowledge extracted from large datasets can provide FDA the opportunity 
to improve the focus of regulatory review, modernize BE assessment 
criteria, and efficiently manage workload by predicting future ANDA 
applications. Further, such knowledge will support industry's efforts 
to optimize their generic drug portfolios to meet upcoming patient and 
market needs. The public workshop will focus on the use and advance of 
quantitative methods and modeling in modernizing generic drug 
development, regulatory review, and product lifecycle management.

II. Scope of Public Input Requested

    FDA seeks input on a range of topics related to the conduct of 
modeling and simulation by pharmaceutical industries and by FDA and on 
the interpretation and use of simulations for risk-based regulatory 
assessment. They include:
    (1) Opportunity areas for model-informed generic drug development 
and review
    (2) Risk-based BE standard for complex and locally acting products:
    a. Under what circumstances would alternative approaches to the 
product-specific BE guidances be encouraged?
    b. What can serve as evidentiary data when proposing alternative BE 
approaches?
    c. What are the scientific and regulatory challenges in using a 
model-based BE approach?
    (3) Emerging quantitative methods and modeling in assisting 
regulatory decision making for drug development and product life cycle 
management:
    a. What are the areas (e.g., excipient selection, molecular target/
mechanism of action-safety profile association, universal exposure 
response models for drugs with the same target) that can benefit most 
in the big data era and what will be the regulatory impact and 
implications?
    b. What are the potential new methods, including but not limited 
to, machine learning and their application areas in assisting drug 
development and review?
    (4) Post-approval evaluation of the substitutability of generic 
products for

[[Page 45865]]

the corresponding reference listed drugs or reference standards:
    a. How to effectively integrate systems pharmacology, PBPK, and the 
exposure-clinical response relationship to evaluate product risk and 
assist BE evaluation?
    b. What will be the next generation methodologies in postmarket 
signal detection to evaluate product substitution or compare product 
performance using the Sentinel database or complementary toolsets?
