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 physiologicallybased 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
VerDate Sep<11>2014
17:47 Dec 18, 2017
Jkt 244001
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 sciencebased initiatives have informed us
during the development of productspecific 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.

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

FOR FURTHER INFORMATION CONTACT:
In
compliance with 44 U.S.C. 3507, FDA
has submitted the following proposed
collection of information to OMB for
review and clearance.
SUPPLEMENTARY INFORMATION:
Good Laboratory Practice Regulations
for Nonclinical Studies—21 CFR Part
58
OMB Control Number 0910–0119—
Extension
Sections 409, 505, 512, and 515 of the
Federal Food, Drug, and Cosmetic Act
(21 U.S.C. 348, 355, 360b, and 360e) and
related statutes require manufacturers of
food additives, human drugs and
biological products, animal drugs, and
medical devices to demonstrate the
safety and utility of their product by
submitting applications to FDA for

research or marketing permits. Such
applications contain, among other
important items, full reports of all
studies done to demonstrate product
safety in man and/or other animals. In
order to ensure adequate quality control
for these studies and to provide an
adequate degree of consumer protection,
the Agency issued good laboratory
practice (GLP) regulations for
nonclinical laboratory studies in part 58
(21 CFR part 58). The regulations
specify minimum standards for the
proper conduct of safety testing and
contain sections on facilities, personnel,
equipment, standard operating
procedures (SOPs), test and control
articles, quality assurance, protocol and
conduct of a safety study, records and
reports, and laboratory disqualification.
Part 58 requires testing facilities
engaged in conducting toxicological
studies to retain, and make available to
regulatory officials, records regarding
compliance with GLPs. Records are
maintained on file at each testing
facility and examined there periodically
by FDA inspectors. The GLP regulations
require that, for each nonclinical
laboratory study, a final report be
prepared that documents the results of
quality assurance unit inspections, test
and control article characterization,
testing of mixtures of test and control
articles with carriers, and an overall
interpretation of nonclinical laboratory
studies. The GLP regulations also
require written records pertaining to: (1)
Personnel job descriptions and
summaries of training and experience;
(2) master schedules, protocols and
amendments thereto, inspection reports,
and SOPs; (3) equipment inspection,
maintenance, calibration, and testing
records; (4) documentation of feed and
water analyses, and animal treatments;
(5) test article accountability records;
and (6) study documentation and raw
data.
Recordkeeping is necessary to
document the conduct of nonclinical
laboratory studies of FDA-regulated
products to ensure the quality and
integrity of the resulting final study
report on which a regulatory decision
may be based. Written SOPs and records
of actions taken are essential for testing
facilities to implement GLPs effectively.
Further, they are essential for FDA to be
able to determine a testing facility’s
compliance with the GLP regulations in
part 58.
In a notice of proposed rulemaking
published in the Federal Register of
August 24, 2016 (81 FR 58342), we
proposed changes in our GLP
regulations, including some of those
listed in tables 1 and 2 of this
document. The document included

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
