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 proposing 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 proposing to amend 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 use 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 proposing to amend 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 proposing to revise 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 proposing to clarify the relationship between established and proprietary names in this context with the use of parentheses.

II. Companion Document to Direct Final Rulemaking

This proposed rule is a companion to the direct final rule published in the final rules section of this issue of the Federal Register. The direct final rule and this companion proposed rule are substantively identical. This companion proposed rule provides the procedural framework to proceed with standard notice-and-comment rulemaking if the direct final rule receives significant adverse comment and is withdrawn. FDA is publishing the direct final rule because we believe the rule is non-controversial and we do not anticipate receiving any significant adverse comments.

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 terminating a direct final rulemaking, 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). Comments that are frivolous, insubstantial, or outside the scope of the rule will not be considered significant or adverse under this procedure. A comment recommending a regulation change in addition to those in the rule would not be considered a significant adverse comment unless the comment states why the rule would be ineffective without the additional change. In addition, if a significant adverse comment applies to an amendment, paragraph, or section of this rule and that provision can be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of a significant adverse comment. The comment period for the companion proposed rule runs concurrently with the comment period of the direct final rule. Any comments received on this companion proposed rule will also be treated as comments on the direct final rule. We will not provide additional opportunity for comment.

If no significant adverse comment is received in response to the direct final rule, no further action will be taken related to this companion proposed rule. Instead, we will publish a document confirming the effective date within 30 days after the comment period ends, and we intend the direct final rule to become effective 30 days after publication of the confirmation notice.

If we receive any significant adverse comments, we will withdraw the direct final rule within 30 days after the comment period ends and proceed to respond to all of the comments under this companion proposed rule using usual notice-and-comment rulemaking procedures. The Agency will address the comments in a subsequent final rule.Start Printed Page 69616

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 proposed 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 proposed 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 proposed 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 proposed rule is not a significant regulatory action as defined by 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 proposed rule would not impose any compliance costs on the sponsors of animal drug products that are currently marketed or in development, the Agency proposes to certify that the 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 proposed rule to result in any 1-year expenditure that would meet or exceed this amount.

VI. Federalism

FDA has analyzed this proposed rule in accordance with the principles set forth in Executive Order 13132. FDA has determined that the proposed rule, if finalized, would not contain policies that would 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 tentatively concludes that the proposed 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 proposed 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 this proposed 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

Interested persons may submit to the Division of Dockets Management (see ADDRESSES) either electronic or written comments regarding this document. It is only necessary to send one set of comments. It is no longer necessary to send two copies of mailed comments. Identify comments with the docket number found in brackets in the heading of this document.
