Direct final rule.


The Food and Drug Administration (FDA) is amending its regulations regarding new animal drugs for minor use and minor species to update language and to clarify the regulations consistent with the explanations in the preambles to the proposed and final rules establishing them. This action is being taken to ensure accuracy and clarity in the Agency's regulations.

Elsewhere in this issue of the Federal Register, FDA is publishing a companion proposed rule, under FDA's usual procedure for notice-and-comment rulemaking, to provide a procedural framework to finalize the rule in the event the Agency receives any significant adverse comments and withdraws this direct final rule. The companion proposed rule and direct final rule are substantively identical.


This rule is effective March 30, 2011. Submit either electronic or written comments by January 31, 2011. If FDA receives no significant adverse comments within the specified comment period, the Agency will publish a document confirming the effective date of the final rule in the Federal Register within 30 days after the comment period on this direct final rule ends. If timely significant adverse comments are received, the Agency will publish a document in the Federal Register withdrawing this direct final rule before its effective date.

I. Background

The Minor Use and Minor Species Animal Health Act of 2004 amended the Federal Food, Drug, and Cosmetic Act (the FD&C Act) to establish new regulatory procedures that provide incentives intended to make more drugs legally available to veterinarians and animal owners for the treatment of minor animal species and uncommon diseases in major animal species. FDA published the final rule to implement these regulations (part 516 (21 CFR part 516)) in the Federal Register of July 26, 2007 (72 FR 41010).

FDA is issuing this direct final rule to amend its regulations regarding new animal drugs for minor use and minor species (MUMS) in part 516 to update language and clarify the intent of the regulations consistent with the preambles to the proposed and final rules.

In § 516.3(b), FDA is amending the definition of “Same dosage form” to make it clearer that the six dosage form categories listed in the regulations under § 516.3(b)(i) through (b)(vi) are the “categories” of dosage forms that the preamble to the proposed rule referenced as follows: “The second test of sameness which the statute establishes to determine eligibility of an animal drug for designation is `same dosage form.' The agency proposes to Start Printed Page 69587use the long-established dosage form categories listed in Title 21 of the Code of Federal Regulations to implement this statutory requirement” (70 FR 56394 at 56398, September 27, 2005). To accomplish this clarification, the amendment will add the word “categories” after the phrase “dosage forms” and remove the “s” from “forms” in the first sentence of the definition.

Section 516.20(b)(2) requires that requests for MUMS designation include “* * * the generic and trade name, if any, of the drug * * *” intended to be designated and FDA is amending this language to replace the terms “generic” and “trade” with the terms “established” and “proprietary”, respectively, because the latter are the terms used in the FD&C Act (see section 502(e) (21 U.S.C. 352(e)). FDA is also revising this language to clarify that “drug” in the context of § 516.20(b)(2) refers to the “active pharmaceutical ingredient (API)” name rather than to a formulated drug product name. The purpose of the information required in this provision of the regulation is to permit the Agency to determine whether a drug is eligible for designation on the basis that it is not the “same drug” as a drug that is already designated, conditionally approved, or approved (see section 573(a)(2)(B) of the FD&C Act (21 U.S.C. 360ccc-2)) and, because the definition of “same drug” in § 516.3(b) requires a knowledge of the drug's “active moiety” in order to make this determination, a request for MUMS designation needs to include the API name. This is because the API name includes the active moiety and the drug product name normally does not. FDA is also clarifying the relationship between established and proprietary names in this context with the use of parentheses.

II. Direct Final Rulemaking

FDA has determined that the subject of this rulemaking is suitable for a direct final rule. FDA is revising part 516 by updating language and clarifying its intent. This rule is intended to make noncontroversial changes to existing regulations. The Agency does not anticipate receiving any significant adverse comment on this rule.

Consistent with FDA's procedures on direct final rulemaking, we are publishing elsewhere in this issue of the Federal Register a companion proposed rule. The companion proposed rule provides the procedural framework within which the rule may be finalized in the event the direct final is withdrawn because of any significant adverse comment. The comment period for this direct final rule runs concurrently with the comment period of the companion proposed rule. Any comments received in response to the companion proposed rule will also be considered as comments regarding this direct rule.

FDA is providing a comment period on the direct final rule of 75 days after the date of publication in the Federal Register. If FDA receives any significant adverse comment, we intend to withdraw this direct final rule before its effective date by publication of a notice in the Federal Register within 30 days after the comment period ends. A significant adverse comment is one that explains why the rule would be inappropriate, including challenges to the rule's underlying premise or approach, or would be ineffective or unacceptable without a change. In determining whether an adverse comment is significant and warrants withdrawing a direct final rule, we will consider whether the comment raises an issue serious enough to warrant a substantive response in a notice-and-comment process in accordance with section 553 of the Administrative Procedure Act (5 U.S.C. 553). A comment recommending a rule change in addition to this rule will not be considered a significant adverse comment unless the comment also states why this rule would be ineffective without the additional change.

If FDA does not receive significant adverse comment, the Agency will publish a document in the Federal Register confirming the effective date of the final rule. The Agency intends to make the direct final rule effective 30 days after publication of the confirmation document in the Federal Register.

A full description of FDA's policy on direct final rule procedures may be found in a guidance document published in the Federal Register of November 21, 1997 (62 FR 62466). The guidance document may be accessed at:​RegulatoryInformation/​Guidances/​ucm125166.htm.

III. Legal Authority

FDA's authority to issue this direct final rule is provided by section 512(b)(1) of the FD&C Act (21 U.S.C. 360b(b)(1)). This section states that any person may file with the Secretary of Health and Human Services an application with respect to any intended use or uses of a new animal drug and sets forth the specific information that must be included in such an application. In addition, section 701(a) of the FD&C Act (21 U.S.C. 371(a)) gives FDA general rulemaking authority to issue regulations for the efficient enforcement of the FD&C Act. FDA is issuing this direct final rule under these authorities.

IV. Environmental Impact

FDA has determined under 21 CFR 25.30(h) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.

V. Analysis of Impacts

FDA has examined the impacts of the final rule under Executive Order 12866 and the Regulatory Flexibility Act (5 U.S.C. 601-612), and the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4). Executive Order 12866 directs agencies to assess all costs and benefits of available regulatory alternatives and, when regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity). The Agency believes that this final rule is not a significant regulatory action under the Executive order.

The Regulatory Flexibility Act requires agencies to analyze regulatory options that would minimize any significant impact of a rule on small entities. Because this direct final rule would not impose any compliance costs on the sponsors of animal drug products that are currently marketed or in development, the Agency certifies that the direct final rule will not have a significant economic impact on a substantial number of small entities.

Section 202(a) of the Unfunded Mandates Reform Act of 1995 requires that agencies prepare a written statement, which includes an assessment of anticipated costs and benefits, before proposing “any rule that includes any Federal mandate that may result in the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more (adjusted annually for inflation) in any one year.” The current threshold after adjustment for inflation is $135 million, using the most current (2009) Implicit Price Deflator for the Gross Domestic Product. FDA does not expect this direct final rule to result in any 1-year expenditure that would meet or exceed this amount.

VI. Federalism

FDA has analyzed this direct final rule in accordance with the principles set forth in Executive Order 13132. FDA has determined that the direct final rule Start Printed Page 69588does not contain policies that have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Accordingly, the Agency has concluded that the rule does not contain policies that have federalism implications as defined in the Executive order and, consequently, a federalism summary impact statement is not required.

VII. Paperwork Reduction Act of 1995

This direct final rule contains information collection provisions that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (the PRA) (44 U.S.C. 3501-3520). The collections of information addressed in the direct final rule have been approved by OMB in accordance with the PRA under the regulations governing designation of new animal drugs for MUMS (part 516, OMB control number 0910-0605). Thus, § 516.20 as amended, does not constitute a new or additional paperwork burden requiring OMB approval.

VIII. Request for Comments
