2021-00189. Potential Approach for Defining Durations of Use for Medically Important Antimicrobial Drugs Intended for Use In or On Feed: A Concept Paper; Request for Comments  

  • Start Preamble

    AGENCY:

    Food and Drug Administration, HHS.

    ACTION:

    Notice; request for comments.

    SUMMARY:

    The Food and Drug Administration (FDA, we, or Agency) is requesting comments on a document entitled “Potential Approach for Defining Durations of Use for Medically Important Antimicrobial Drugs Intended for Use In or On Feed: A Concept Paper.” The concept paper outlines a potential framework for how sponsors of new animal drug products containing medically important antimicrobial drugs approved for use in or on animal feed might voluntarily establish appropriately defined durations of therapeutic administration to food-producing animals where none currently exist. Establishing appropriately defined durations of use to mitigate development of antimicrobial resistance would be consistent with previous efforts by FDA to protect public health by promoting the judicious use of these drugs in food-producing animals.

    DATES:

    Submit either electronic or written comments by April 12, 2021.

    SUPPLEMENTARY INFORMATION:

    I. Background

    In response to recommendations made by FDA in Guidance for Industry (GFI) #213,[1] as part of a strategy to address antimicrobial resistance associated with the use of antimicrobial drugs in animal agriculture, sponsors of all new animal drugs containing antimicrobial drugs important to human medicine (medically important antimicrobial drugs) approved for use in or on the feed or in the drinking water of food-producing animals worked with FDA over a 3-year period from 2013 to 2016 to voluntarily withdraw approval of indications that were not considered necessary for assuring animal health (production indications) and to voluntarily change the marketing status of all remaining approved uses of such new animal drugs from “over the counter” to either by veterinary prescription or by veterinary feed directive, as applicable.

    In September 2016, FDA announced that it intended to enter the next phase of its efforts to mitigate antimicrobial resistance by focusing on medically important antimicrobial drugs used in animal feed or water that have at least one therapeutic indication without a defined duration of use. In a notice published in the Federal Register on September 14, 2016 (81 FR 63187), the Agency requested information from the public about how to establish appropriately targeted durations of use for therapeutic products affected by GFI #213 with no defined duration of use. Public feedback received in response to that request for information was taken into consideration during development of this concept paper.

    On September 14, 2018, FDA released a 5-year action plan for supporting antimicrobial stewardship in veterinary settings.[2] This plan includes an action item intended to ensure that all medically important antimicrobial drugs used in or on the feed or drinking water of food-producing animals have an appropriately targeted duration of use.[3]

    II. Request for Comments

    We are requesting early input and comments from the public on a concept paper that outlines a potential framework for how sponsors of approved new animal drug applications and abbreviated new animal drug applications for products containing medically important antimicrobial drugs for use in or on the feed of food-producing animals could voluntarily change the approved conditions of use of these drugs to establish appropriately defined durations of use for those indications that currently have an undefined duration of use. A copy of the concept paper may be obtained as described in section III below.

    For the purpose of this potential framework, the term “undefined duration of use” means that for one or more of the indications for which the drug is approved, the product's labeling either includes no information regarding the duration of administration or otherwise does not provide an appropriately targeted duration of use. Although FDA's 5-year action plan for supporting antimicrobial stewardship that issued in September 2018 included an action item calling for the Agency to develop a strategy for establishing appropriately defined durations of use for medically important antimicrobial drugs used in or on the feed or drinking water of food-producing animals, the Center for Veterinary Medicine later determined that all of the approved uses of medically important antimicrobial drugs in dosage forms other than feed already have appropriately defined durations of use. For this reason, the scope of the concept paper is limited to those drugs that are approved for use in or on medicated feed.

    The concept paper is intended to outline for sponsors and other stakeholders a potential process framework for how to make voluntary changes to the approved conditions of use of their medically important antimicrobial drugs administered in or on the medicated feed of food-producing animals to establish appropriately defined durations of use where none currently exist. Establishing appropriately defined durations of use to mitigate the development of antimicrobial resistance would be consistent with previous efforts by FDA to protect public health by promoting the judicious use of these drugs in food-producing animals.

    Under the potential framework described in the concept paper, the process for revising the conditions of use would include making changes to the approved labeling for the product to appropriately define duration of use and, when appropriate, providing additional information to be included on the product's labeling that would be relevant to the veterinarian in determining when drug administration should be initiated or stopped in accordance with the approved labeling and consistent with the principles of judicious use of antimicrobials. In addition, were the potential framework later to be adopted through guidance, sponsors who choose to voluntarily establish appropriately defined durations of use for their products would be expected to submit data or other information supporting effectiveness at the shortest duration of use proposed for the labeling.

    The potential framework includes a possible timeline for sponsors, with two phases: Phase 1, reassessing the existing data used to support the original approval of the affected product indications, considering what additional data or information might be needed, and formulating plans to obtain such data or information; and Phase 2, taking steps to obtain approval of revisions to conditions of use for their affected products. The potential framework also includes possible timelines for making labeling changes to combination proprietary free-choice medicated feeds and generic products, as well as a possible timeline for sponsors who intend to voluntarily withdraw the approval of an indication or an entire application rather than submit data or other information to define a duration of use.

    We do not intend for the concept paper described in this notice to produce any decisions or new positions on specific regulatory issues or processes. Rather, the intent is to gather Start Printed Page 1981information and obtain early input from the public on a potential framework for how sponsors may voluntarily change the approved conditions of use of medically important antimicrobial drugs used in or on the medicated feed of food-producing animals to establish an appropriately defined duration of use for those indications that currently have an undefined duration of use. The concept paper does not contain recommendations and does not constitute draft or final guidance by FDA. It should not be used for any purpose other than to facilitate public comment. FDA intends to consider all information and comments received on the concept paper before issuing draft guidance for additional comment.

    We are specifically interested in receiving public comments on the following questions:

    1. Are the potential timeframes outlined in the concept paper reasonable to achieve the goals described in the concept paper? If not, are there specific scientific or administrative barriers that would prevent sponsors from meeting these timeframes?

    2. Are the potential processes for revising the applications described in the concept paper reasonable? If not, what specific adjustments could be made to improve these processes?

    3. Are there other factors we should consider regarding this potential framework? If so, what are they?

    III. Electronic Access
