SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing a public meeting entitled ``Incorporating 
Alternative Approaches in Clinical Investigations for New Animal 
Drugs.'' This public meeting and request for comment is intended to 
support FDA guidance development as required under section 305 of the 
Animal Drug and Animal Generic Drug User Fee Amendments of 2018 (Pub. 
L. 115-234). Section 305 directs FDA to develop guidance to address 
several alternative approaches in clinical investigations for new 
animal drugs, including incorporating complex adaptive and other novel 
investigation designs, data from foreign countries, real world evidence 
(including ongoing surveillance activities, observational studies, and 
registry data), biomarkers, and surrogate endpoints into proposed 
clinical investigation protocols and applications for new animal drugs 
under sections 512 and 571 of the FD&C Act (21 U.S.C. 360b, 360ccc). 
Section 305 also directs FDA to conduct a public meeting to allow the 
Agency to gather input from stakeholders, including representatives of 
regulated industry, consumer groups, academia, veterinarians, and food 
producers before developing the guidance.

II. Topics for Discussion at the Public Meeting

    The purpose of this public meeting is to facilitate discussion and 
obtain input from stakeholders about the use of complex adaptive and 
other novel investigation designs, data from foreign countries, real 
world evidence, and biomarkers and surrogate endpoints in drug 
development and regulatory decision making.
    The meeting is expected to include four sessions that focus on the 
following topics: (1) Complex adaptive and other novel investigation 
designs; (2) data from foreign countries; (3) real world evidence; and, 
(4) biomarkers and surrogate endpoints. Within each session and 
following all sessions there will be an opportunity for public comment. 
To facilitate the development of guidance on these topics, please 
consider the following questions. When responding please identify the 
topic and question in your response.

Topic 1: Complex Adaptive and Other Novel Investigation Designs

    1. In September 2018, FDA published draft Guidance for Industry: 
Adaptive Designs for Clinical Trials of Drugs and Biologics, which 
applies to human drugs and biologics (https://www.fda.gov/regulatory-information/search-fda-guidance-documents/adaptive-design-clinical-trials-drugs-and-biologics). How should these apply to study designs 
for animal drugs? What are the potential study adaptation features that 
could be applied to animal drug investigations? What are the challenges 
and possible solutions to apply these adaptations to studies for animal 
drugs? To what type of studies for animal drugs would these study 
designs be most applicable?
    2. How does complex adaptive design differ from adaptive design? 
What constitutes other novel investigation designs? What examples are 
directly applicable to animal drug development?
    3. Are there partnerships that can be formed between FDA and the 
regulated industry, academia, or other groups to facilitate the 
development or use of these novel investigational designs for animal 
drug development? What strategic work is needed to enable the regulated 
industry to make full use of these novel investigational designs for 
animal drug development? What methods are needed, such as the use of 
simulations or modeling, to facilitate the use of these novel 
investigational designs for animal drug development?

Topic 2: Data From Foreign Countries

    For the purposes of this meeting, FDA considers data from foreign 
countries to be data from investigations or studies conducted outside 
the United States (U.S.). FDA can accept data from studies conducted 
outside the United States to support a new animal drug application, 
provided the applicant demonstrates that the data are adequate under 
applicable standards to support approval (section 569B of the FD&C Act; 
21 U.S.C. 360bbb-8b). FDA also accepts data from studies conducted 
outside the United States to support a food additive petition for a 
food additive intended for use in animal food, when provided by the 
petitioner (section 409(k)(1) of the FD&C Act; 21 U.S.C. 348(k)(1)). 
While the regulatory standards for approval differ between animal drugs 
and animal food additives, data from foreign countries can be used to 
support either approval if the data meet the appropriate regulatory 
standards.
    1. What challenges and potential solutions do you have in meeting 
the requirements of substantial evidence of effectiveness, as defined 
in 21 CFR 514.4, when using data from foreign countries for an animal 
drug?
    2. Typically in the United States, when we wish to show a test drug 
is no worse than an active control, that active control is an approved 
animal drug in the United States. A non-inferiority analysis is used to 
statistically demonstrate this relationship. In studies conducted 
outside the United States, an active control may be used that is not 
approved for that use in the United States. In the absence of a U.S. 
approval for the active control, FDA cannot interpret non-inferiority 
to the unapproved active control. What challenges exist in utilizing 
these studies? What criteria should FDA use to accept a study where the 
active control is not approved in the United

[[Page 32751]]

States? What are potential options or solutions to enable FDA to use 
these studies?
    3. What challenges exist in demonstrating that data from foreign 
countries were generated under conditions representative of typical 
conditions in the United States for an animal drug or food additive? 
What are potential solutions to these challenges?
    4. What challenges exist in designing studies for an animal drug or 
food additive to meet the approval requirements of different 
jurisdictions? What are possible solutions to these challenges?
    5. What challenges exist in study conduct and the collection and 
interpretability of data from foreign countries (both manual and 
electronic) that may influence study quality and data integrity to 
support the approval of an animal drug or food additive? What are 
possible solutions to these challenges?
    6. What other challenges have you encountered and what potential 
solutions would you propose with regard to providing data from foreign 
countries to FDA?

Topic 3: Real World Evidence

    There is significant activity within FDA aimed at clarifying how to 
determine if real-world data (RWD) are sufficient to generate real-
world evidence (RWE) that could be used for regulatory decision making 
by the Agency. In August 2017, FDA published a guidance document 
entitled, ``Guidance for Industry and Food and Drug Administration 
Staff: Use of Real-World Evidence to Support Regulatory Decision-Making 
for Medical Devices'' (available at https://www.fda.gov/media/99447/download) and, in accordance with the 21st Century Cures Act (Pub. L. 
114-255), released a draft framework entitled ``Framework for FDA's 
Real-World Evidence Program'' (available at https://www.fda.gov/media/120060/download) in December 2018 for human drug and biological 
products.
    1. How should FDA define RWE for making regulatory decisions for 
animal drugs? What sources of RWD should FDA consider to generate RWE 
for animal drugs?
    2. What challenges exist for the use of RWE for animal drug 
approvals? What are possible solutions to these challenges?
    3. In what contexts might RWD/RWE be used to generate clinical 
evidence for regulatory decision making for animal drugs?
    4. What factors should FDA consider when evaluating RWE for animal 
drugs?

Topic 4: Biomarkers and Surrogate Endpoints

    Biomarkers have long been a part of veterinary medicine. Examples 
include routine tests such as body temperature, heart rate, complete 
blood cell count and clinical chemistry, radiographs, and intraocular 
pressure. Numerous technological advancements have greatly increased 
the number of available biomarkers while reducing their cost. 
Unfortunately, many potential biomarkers are not validated for their 
use and interpretation in clinical investigations. FDA's Center for 
Drug Evaluation and Research (CDER) has a formal Biomarker 
Qualification Program, related guidance, and affiliated consortia to 
support the development and use of biomarkers in regulatory decision 
making for human drugs (https://www.fda.gov/drugs/drug-development-tool-qualification-programs/cder-biomarker-qualification-program). FDA 
is seeking stakeholder feedback on how to best support the 
identification and development of new biomarkers for new animal drug 
applications and on ways to better incorporate biomarkers and surrogate 
endpoints into animal drug development.
    1. What are the expectations of sponsors, researchers, 
veterinarians, and producers for the use of biomarkers in the context 
of animal drug regulation and how might biomarkers be used in addition 
to surrogate endpoints in the design and conduct of clinical studies?
    2. Biomarkers are commonly used for diagnosing disease to enroll 
patients, sample size estimations, and pilot/proof-of-concept studies. 
What information should be provided to FDA to support their use in 
these contexts (e.g., analytical validation, clinical validation, 
establishing clinical utility, companion diagnostics etc.)?
    3. What are the major challenges in translating potential 
biomarkers and/or surrogate endpoints into practical tools in clinical 
trials? What are possible solutions to these challenges?
    4. How do we determine the evidentiary criteria for evaluating 
biomarker use?
    5. Should FDA's Center for Veterinary Medicine develop a biomarker 
qualification program like CDER's? Would such a program be beneficial, 
and is it something that stakeholders (e.g., drug sponsors) would use? 
Are there other approaches to the development and acceptance of 
biomarkers for animal drugs?
