# §360b. New animal drugs

- (a) **Unsafe new animal drugs and animal feed containing such drugs; conditions of safety; exemption of drugs for research; import tolerances—**
  - (1) A [new animal drug](/usc/21/321.md?p=v) shall, with respect to any particular use or intended use of such [drug](/usc/21/321.md?p=g-1), be deemed unsafe for purposes of [section 351(a)(5) of this title](/usc/21/351.md) and [section 342(a)(2)(C)(ii) of this title](/usc/21/342.md) unless—
    - (A) there is in effect an approval of an application filed pursuant to [subsection (b)](#b) with respect to such use or intended use of such [drug](/usc/21/321.md?p=g-1), and such [drug](/usc/21/321.md?p=g-1), its [labeling](/usc/21/321.md?p=m), and such use conform to such approved application;
    - (B) there is in effect a conditional approval of an application filed pursuant to [section 360ccc of this title](/usc/21/360ccc.md) with respect to such use or intended use of such [drug](/usc/21/321.md?p=g-1), and such [drug](/usc/21/321.md?p=g-1), its [labeling](/usc/21/321.md?p=m), and such use conform to such conditionally approved application;
    - (C) there is in effect an index listing pursuant to [section 360ccc–1 of this title](/usc/21/360ccc–1.md) with respect to such use or intended use of such [drug](/usc/21/321.md?p=g-1) in a [minor species](/usc/21/321.md?p=oo), and such [drug](/usc/21/321.md?p=g-1), its [labeling](/usc/21/321.md?p=m), and such use conform to such index listing; or
    - (D) there is in effect an authorization pursuant to [section 360bbb–3 of this title](/usc/21/360bbb–3.md) with respect to such use or intended use of such [drug](/usc/21/321.md?p=g-1), and such [drug](/usc/21/321.md?p=g-1), its [labeling](/usc/21/321.md?p=m), and such use conform to any conditions of such authorization.

    A [new animal drug](/usc/21/321.md?p=v) shall also be deemed unsafe for such purposes in the event of removal from the establishment of a [manufacturer](/usc/21/360hh.md?p=3), packer, or distributor of such [drug](/usc/21/321.md?p=g-1) for use in the manufacture of [animal feed](/usc/21/321.md?p=w) in any [State](/usc/21/321.md?p=a-1) unless at the time of such removal such [manufacturer](/usc/21/360hh.md?p=3), packer, or distributor has an unrevoked written statement from the consignee of such [drug](/usc/21/321.md?p=g-1), or notice from the [Secretary](/usc/21/321.md?p=d), to the effect that, with respect to the use of such [drug](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w), such consignee (i) holds a license issued under [subsection (m)](#m) and has in its possession current approved [labeling](/usc/21/321.md?p=m) for such [drug](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w); or (ii) will, if the consignee is not a user of the [drug](/usc/21/321.md?p=g-1), ship such [drug](/usc/21/321.md?p=g-1) only to a holder of a license issued under [subsection (m)](#m).

  - (2) An [animal feed](/usc/21/321.md?p=w) bearing or containing a [new animal drug](/usc/21/321.md?p=v) shall, with respect to any particular use or intended use of such [animal feed](/usc/21/321.md?p=w) be deemed unsafe for purposes of [section 351(a)(6) of this title](/usc/21/351.md) unless—
    - (A) there is in effect—
      - (i) an approval of an application filed pursuant to [subsection (b)](#b) with respect to such [drug](/usc/21/321.md?p=g-1), as used in such [animal feed](/usc/21/321.md?p=w), and such [animal feed](/usc/21/321.md?p=w) and its [labeling](/usc/21/321.md?p=m), [distribution](/usc/21/360eee.md?p=5), holding, and use conform to such approved application;
      - (ii) a conditional approval of an application filed pursuant to [section 360ccc of this title](/usc/21/360ccc.md) with respect to such [drug](/usc/21/321.md?p=g-1), as used in such [animal feed](/usc/21/321.md?p=w), and such [animal feed](/usc/21/321.md?p=w) and its [labeling](/usc/21/321.md?p=m), [distribution](/usc/21/360eee.md?p=5), holding, and use conform to such conditionally approved application; or
      - (iii) an index listing pursuant to [section 360ccc–1 of this title](/usc/21/360ccc–1.md) with respect to such [drug](/usc/21/321.md?p=g-1), as used in such [animal feed](/usc/21/321.md?p=w), and such [animal feed](/usc/21/321.md?p=w) and its [labeling](/usc/21/321.md?p=m), [distribution](/usc/21/360eee.md?p=5), holding, and use conform to such index listing; and
    - (B) such [animal feed](/usc/21/321.md?p=w) is manufactured at a site for which there is in effect a license issued pursuant to [subsection (m)(1)](#m-1) to manufacture such [animal feed](/usc/21/321.md?p=w).
  - (3) A [new animal drug](/usc/21/321.md?p=v) or an [animal feed](/usc/21/321.md?p=w) bearing or containing a [new animal drug](/usc/21/321.md?p=v) shall not be deemed unsafe for the purposes of [section 351(a)(5)](/usc/21/351.md) or (6) of this title if such article is for investigational use and conforms to the terms of an exemption in effect with respect thereto under [subsection (j)](#j).
  - (4)
    - (A) Except as provided in [subparagraph (B)](#a-4-B), if an approval of an application filed under [subsection (b)](#b) is in effect with respect to a particular use or intended use of a [new animal drug](/usc/21/321.md?p=v), the [drug](/usc/21/321.md?p=g-1) shall not be deemed unsafe for the purposes of [paragraph (1)](#a-1) and shall be exempt from the requirements of [section 352(f) of this title](/usc/21/352.md?p=f) with respect to a different use or intended use of the [drug](/usc/21/321.md?p=g-1), other than a use in or on [animal feed](/usc/21/321.md?p=w), if such use or intended use—
      - (i) is by or on the lawful written or oral order of a [licensed](/usc/21/360eee.md?p=9) veterinarian within the context of a veterinarian-client-patient relationship, as defined by the [Secretary](/usc/21/321.md?p=d); and
      - (ii) is in compliance with regulations promulgated by the [Secretary](/usc/21/321.md?p=d) that establish the conditions for such different use or intended use.

      The regulations promulgated by the [Secretary](/usc/21/321.md?p=d) under [clause (ii)](#a-4-A-ii) may prohibit particular uses of an animal [drug](/usc/21/321.md?p=g-1) and shall not permit such different use of an animal [drug](/usc/21/321.md?p=g-1) if the [labeling](/usc/21/321.md?p=m) of another animal [drug](/usc/21/321.md?p=g-1) that contains the same active ingredient and which is in the same dosage form and concentration provides for such different use.

    - (B) If the [Secretary](/usc/21/321.md?p=d) finds that there is a reasonable probability that a use of an animal [drug](/usc/21/321.md?p=g-1) [authorized](/usc/21/360eee.md?p=2) under [subparagraph (A)](#a-4-A) may present a risk to the public health, the [Secretary](/usc/21/321.md?p=d) may—
      - (i) establish a [safe](/usc/21/321.md?p=u) level for a residue of an animal [drug](/usc/21/321.md?p=g-1) when it is used for such different use [authorized](/usc/21/360eee.md?p=2) by [subparagraph (A)](#a-4-A); and
      - (ii) require the development of a practical, analytical method for the detection of residues of such [drug](/usc/21/321.md?p=g-1) above the [safe](/usc/21/321.md?p=u) level established under [clause (i)](#a-4-B-i).

      The use of an animal [drug](/usc/21/321.md?p=g-1) that results in residues exceeding a [safe](/usc/21/321.md?p=u) level established under [clause (i)](#a-4-B-i) shall be considered an unsafe use of such [drug](/usc/21/321.md?p=g-1) under [paragraph (1)](#a-1). [Safe](/usc/21/321.md?p=u) levels may be established under [clause (i)](#a-4-B-i) either by regulation or order.

    - (C) The [Secretary](/usc/21/321.md?p=d) may by general regulation provide access to the records of veterinarians to ascertain any use or intended use [authorized](/usc/21/360eee.md?p=2) under [subparagraph (A)](#a-4-A) that the [Secretary](/usc/21/321.md?p=d) has determined may present a risk to the public health.
    - (D) If the [Secretary](/usc/21/321.md?p=d) finds, after affording an opportunity for public comment, that a use of an animal [drug](/usc/21/321.md?p=g-1) [authorized](/usc/21/360eee.md?p=2) under [subparagraph (A)](#a-4-A) presents a risk to the public health or that an analytical method required under [subparagraph (B)](#a-4-B) has not been developed and submitted to the [Secretary](/usc/21/321.md?p=d), the [Secretary](/usc/21/321.md?p=d) may, by order, prohibit any such use.
  - (5) If the approval of an application filed under [section 355 of this title](/usc/21/355.md) is in effect, the [drug](/usc/21/321.md?p=g-1) under such application shall not be deemed unsafe for purposes of [paragraph (1)](#a-1) and shall be exempt from the requirements of [section 352(f) of this title](/usc/21/352.md?p=f) with respect to a use or intended use of the [drug](/usc/21/321.md?p=g-1) in animals if such use or intended use—
    - (A) is by or on the lawful written or oral order of a [licensed](/usc/21/360eee.md?p=9) veterinarian within the context of a veterinarian-client-patient relationship, as defined by the [Secretary](/usc/21/321.md?p=d); and
    - (B) is in compliance with regulations promulgated by the [Secretary](/usc/21/321.md?p=d) that establish the conditions for the use or intended use of the [drug](/usc/21/321.md?p=g-1) in animals.
  - (6) For purposes of [section 342(a)(2)(D)](/usc/21/342.md)[^1] of this title, a use or intended use of a [new animal drug](/usc/21/321.md?p=v) shall not be deemed unsafe under this section if the [Secretary](/usc/21/321.md?p=d) establishes a tolerance for such [drug](/usc/21/321.md?p=g-1) and any edible portion of any animal imported into the United States does not contain residues exceeding such tolerance. In establishing such tolerance, the [Secretary](/usc/21/321.md?p=d) shall rely on data sufficient to demonstrate that a proposed tolerance is [safe](/usc/21/321.md?p=u) based on similar [food](/usc/21/321.md?p=f) safety criteria used by the [Secretary](/usc/21/321.md?p=d) to establish tolerances for applications for [new animal drugs](/usc/21/321.md?p=v) filed under [subsection (b)(1)](#b-1). The [Secretary](/usc/21/321.md?p=d) may consider and rely on data submitted by the [drug](/usc/21/321.md?p=g-1) [manufacturer](/usc/21/360hh.md?p=3), including data submitted to appropriate regulatory authorities in any country where the [new animal drug](/usc/21/321.md?p=v) is lawfully used or data available from a relevant international organization, to the extent such data are not inconsistent with the criteria used by the [Secretary](/usc/21/321.md?p=d) to establish a tolerance for applications for [new animal drugs](/usc/21/321.md?p=v) filed under [subsection (b)(1)](#b-1). For purposes of this paragraph, “relevant international organization” means the Codex Alimenterius[^2] Commission or other international organization deemed appropriate by the [Secretary](/usc/21/321.md?p=d). The [Secretary](/usc/21/321.md?p=d) may, under procedures specified by regulation, revoke a tolerance established under this paragraph if information demonstrates that the use of the [new animal drug](/usc/21/321.md?p=v) under actual use conditions results in [food](/usc/21/321.md?p=f) being imported into the United States with residues exceeding the tolerance or if scientific evidence shows the tolerance to be unsafe.
- (b) **Filing application for uses of new animal drug; contents; patent information; abbreviated application; presubmission conference—**
  - (1) Any [person](/usc/21/321.md?p=e) may file with the [Secretary](/usc/21/321.md?p=d) an application with respect to any intended use or uses of a [new animal drug](/usc/21/321.md?p=v). Such [person](/usc/21/321.md?p=e) shall submit to the [Secretary](/usc/21/321.md?p=d) as a part of the application (A) full reports of investigations which have been made to show whether or not such [drug](/usc/21/321.md?p=g-1) is [safe](/usc/21/321.md?p=u) and effective for use; (B) a full list of the articles used as components of such [drug](/usc/21/321.md?p=g-1); (C) a full statement of the composition of such [drug](/usc/21/321.md?p=g-1); (D) a full description of the methods used in, and the facilities and controls used for, the manufacture, processing, and packing of such [drug](/usc/21/321.md?p=g-1); (E) such samples of such [drug](/usc/21/321.md?p=g-1) and of the articles used as components thereof, of any [animal feed](/usc/21/321.md?p=w) for use in or on which such [drug](/usc/21/321.md?p=g-1) is intended, and of the edible portions or [products](/usc/21/360eee.md?p=13) (before or after slaughter) of animals to which such [drug](/usc/21/321.md?p=g-1) (directly or in or on [animal feed](/usc/21/321.md?p=w)) is intended to be administered, as the [Secretary](/usc/21/321.md?p=d) may require; (F) specimens of the [labeling](/usc/21/321.md?p=m) proposed to be used for such [drug](/usc/21/321.md?p=g-1), or in case such [drug](/usc/21/321.md?p=g-1) is intended for use in [animal feed](/usc/21/321.md?p=w), proposed [labeling](/usc/21/321.md?p=m) appropriate for such use, and specimens of the [labeling](/usc/21/321.md?p=m) for the [drug](/usc/21/321.md?p=g-1) to be manufactured, packed, or distributed by the applicant; (G) a description of practicable methods for determining the quantity, if any, of such [drug](/usc/21/321.md?p=g-1) in or on [food](/usc/21/321.md?p=f), and any substance formed in or on [food](/usc/21/321.md?p=f), because of its use; and (H) the proposed tolerance or withdrawal period or other use restrictions for such [drug](/usc/21/321.md?p=g-1) if any tolerance or withdrawal period or other use restrictions are required in order to assure that the proposed use of such [drug](/usc/21/321.md?p=g-1) will be [safe](/usc/21/321.md?p=u). The applicant shall file with the application the patent number and the expiration date of any patent which claims the [new animal drug](/usc/21/321.md?p=v) for which the applicant filed the application or which claims a method of using such [drug](/usc/21/321.md?p=g-1) and with respect to which a claim of patent infringement could reasonably be asserted if a [person](/usc/21/321.md?p=e) not [licensed](/usc/21/360eee.md?p=9) by the owner engaged in the manufacture, use, or sale of the [drug](/usc/21/321.md?p=g-1). If an application is filed under this subsection for a [drug](/usc/21/321.md?p=g-1) and a patent which claims such [drug](/usc/21/321.md?p=g-1) or a method of using such [drug](/usc/21/321.md?p=g-1) is issued after the filing date but before approval of the application, the applicant shall amend the application to include the information required by the preceding sentence. Upon approval of the application, the [Secretary](/usc/21/321.md?p=d) shall publish information submitted under the two preceding sentences.
  - (2) Any [person](/usc/21/321.md?p=e) may file with the [Secretary](/usc/21/321.md?p=d) an abbreviated application for the approval of a [new animal drug](/usc/21/321.md?p=v). An abbreviated application shall contain the information required by [subsection (n)](#n).
  - (3) Any [person](/usc/21/321.md?p=e) intending to file an application under [paragraph (1)](#b-1), [section 360ccc of this title](/usc/21/360ccc.md), or a request for an investigational exemption under [subsection (j)](#j) shall be entitled to one or more conferences prior to such submission to reach an agreement acceptable to the [Secretary](/usc/21/321.md?p=d) establishing a submission or an investigational requirement, which may include a requirement for a field investigation. A decision establishing a submission or an investigational requirement shall bind the [Secretary](/usc/21/321.md?p=d) and the applicant or requestor unless (A) the [Secretary](/usc/21/321.md?p=d) and the applicant or requestor mutually agree to modify the requirement, or (B) the [Secretary](/usc/21/321.md?p=d) by written order determines that a substantiated scientific requirement essential to the determination of safety or effectiveness of the animal [drug](/usc/21/321.md?p=g-1) involved has appeared after the conference. No later than 25 calendar days after each such conference, the [Secretary](/usc/21/321.md?p=d) shall provide a written order setting forth a scientific justification specific to the animal [drug](/usc/21/321.md?p=g-1) and intended uses under consideration if the agreement referred to in the first sentence requires more than one field investigation as being essential to provide substantial evidence of effectiveness for the intended uses of the [drug](/usc/21/321.md?p=g-1). Nothing in this paragraph shall be construed as compelling the [Secretary](/usc/21/321.md?p=d) to require a field investigation.
  - (4) Beginning on October 1, 2018, all applications or submissions pursuant to this subsection shall be submitted by electronic means in such format as the [Secretary](/usc/21/321.md?p=d) may require.
- (c) **Period for submission and approval of application; period for notice and expedition of hearing; period for issuance of order; abbreviated applications; withdrawal periods; effective date of approval; relationship to other applications; withdrawal or suspension of approval; bioequivalence; filing of additional patent information—**
  - (1) Within one hundred and eighty days after the filing of an application pursuant to [subsection (b)](#b), or such additional period as may be agreed upon by the [Secretary](/usc/21/321.md?p=d) and the applicant, the [Secretary](/usc/21/321.md?p=d) shall either (A) issue an order approving the application if he then finds that none of the grounds for denying approval specified in [subsection (d)](#d) applies, or (B) give the applicant notice of an opportunity for a hearing before the [Secretary](/usc/21/321.md?p=d) under [subsection (d)](#d) on the question whether such application is approvable. If the applicant elects to accept the opportunity for a hearing by written request within thirty days after such notice, such hearing shall commence not more than ninety days after the expiration of such thirty days unless the [Secretary](/usc/21/321.md?p=d) and the applicant otherwise agree. Any such hearing shall thereafter be conducted on an expedited basis and the [Secretary](/usc/21/321.md?p=d)’s order thereon shall be issued within ninety days after the date fixed by the [Secretary](/usc/21/321.md?p=d) for filing final briefs.
  - (2)
    - (A) Subject to [subparagraph (C)](#c-2-C), the [Secretary](/usc/21/321.md?p=d) shall approve an abbreviated application for a [drug](/usc/21/321.md?p=g-1) unless the [Secretary](/usc/21/321.md?p=d) finds—
      - (i) the methods used in, or the facilities and controls used for, the manufacture, processing, and packing of the [drug](/usc/21/321.md?p=g-1) are inadequate to assure and preserve its identity, strength, quality, and purity;
      - (ii) the conditions of use prescribed, recommended, or suggested in the proposed [labeling](/usc/21/321.md?p=m) are not reasonably certain to be followed in practice or, except as provided in [subparagraph (B)](#c-2-B), information submitted with the application is insufficient to show that each of the proposed conditions of use or similar limitations (whether in the [labeling](/usc/21/321.md?p=m) or published pursuant to [subsection (i)](#i)) have been previously approved for the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application;
      - (iii) information submitted with the application is insufficient to show that the active ingredients are the same as those of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application;
      - (iv)
        - (I) if the application is for a [drug](/usc/21/321.md?p=g-1) whose active ingredients, route of administration, dosage form, strength, or use with other animal [drugs](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w) is the same as the active ingredients, route of administration, dosage form, strength, or use with other animal [drugs](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w) of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application, information submitted in the application is insufficient to show that the active ingredients, route of administration, dosage form, strength, or use with other animal [drugs](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w) is the same as that of the approved [new animal drug](/usc/21/321.md?p=v), or
        - (II) if the application is for a [drug](/usc/21/321.md?p=g-1) whose active ingredients, route of administration, dosage form, strength, or use with other animal [drugs](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w) is different from that of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application, no petition to file an application for the [drug](/usc/21/321.md?p=g-1) with the different active ingredients, route of administration, dosage form, strength, or use with other animal [drugs](/usc/21/321.md?p=g-1) in [animal feed](/usc/21/321.md?p=w) was approved under [subsection (n)(3)](#n-3);

If such an action is brought before the expiration of such days, the approval shall be made effective upon the expiration of the 30 month period beginning on the date of the receipt of the notice provided under [subsection (n)(2)(B)](#n-2-B) or such shorter or longer period as the court may order because either party to the action failed to reasonably cooperate in expediting the action, except that if before the expiration of such period—
        - (I) the court decides that such patent is invalid or not infringed, the approval shall be made effective on the date of the court decision,
        - (II) the court decides that such patent has been infringed, the approval shall be made effective on such date as the court orders under [section 271(e)(4)(A) of title 35](/usc/35/271.md?p=e-4-A), or
        - (III) the court grants a preliminary injunction prohibiting the applicant from engaging in the commercial manufacture or sale of the [drug](/usc/21/321.md?p=g-1) until the court decides the issues of patent validity and infringement and if the court decides that such patent is invalid or not infringed, the approval shall be made effective on the date of such court decision.

        In such an action, each of the parties shall reasonably cooperate in expediting the action. Until the expiration of 45 days from the date the notice made under [subsection (n)(2)(B)](#n-2-B) is received, no action may be brought under [section 2201 of title 28](/usc/28/2201.md) for a declaratory judgment with respect to the patent. Any action brought under [section 2201 of title 28](/usc/28/2201.md) shall be brought in the judicial district where the defendant has its principal place of business or a regular and established place of business.

      - (iv) If the application contains a certification described in clause (iv) of subsection (n)(1)(G) and is for a [drug](/usc/21/321.md?p=g-1) for which a previous application has been filed under this subsection containing such a certification, the application shall be made effective not earlier than 180 days after—
        - (I) the date the [Secretary](/usc/21/321.md?p=d) receives notice from the applicant under the previous application of the first commercial marketing of the [drug](/usc/21/321.md?p=g-1) under the previous application, or
        - (II) the date of a decision of a court in an action described in subclause (III)[^3] holding the patent which is the subject of the certification to be invalid or not infringed,

        whichever is earlier.

    - (E) If the [Secretary](/usc/21/321.md?p=d) decides to disapprove an application, the [Secretary](/usc/21/321.md?p=d) shall give the applicant notice of an opportunity for a hearing before the [Secretary](/usc/21/321.md?p=d) on the question of whether such application is approvable. If the applicant elects to accept the opportunity for hearing by written request within 30 days after such notice, such hearing shall commence not more than 90 days after the expiration of such 30 days unless the [Secretary](/usc/21/321.md?p=d) and the applicant otherwise agree. Any such hearing shall thereafter be conducted on an expedited basis and the [Secretary](/usc/21/321.md?p=d)’s order thereon shall be issued within 90 days after the date fixed by the [Secretary](/usc/21/321.md?p=d) for filing final briefs.

      - (i) for the same period as the withdrawal or suspension under [subsection (e)](#e) or this subparagraph, or
      - (ii) if the approved [new animal drug](/usc/21/321.md?p=v) has been withdrawn from sale, for the period of withdrawal from sale or, if earlier, the period ending on the date the [Secretary](/usc/21/321.md?p=d) determines that the withdrawal from sale is not for safety or effectiveness reasons.
    - (H) For purposes of this paragraph:
      - (i) The term “bioequivalence” means the rate and extent to which the active ingredient or therapeutic ingredient is absorbed from a [new animal drug](/usc/21/321.md?p=v) and becomes available at the site of [drug](/usc/21/321.md?p=g-1) action.
      - (ii) A [new animal drug](/usc/21/321.md?p=v) shall be considered to be bioequivalent to the approved [new animal drug](/usc/21/321.md?p=v) referred to in its application under [subsection (n)](#n) if—
        - (I) the rate and extent of absorption of the [drug](/usc/21/321.md?p=g-1) do not show a significant difference from the rate and extent of absorption of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application when administered at the same dose of the active ingredient under similar experimental conditions in either a single dose or multiple doses;
        - (II) the extent of absorption of the [drug](/usc/21/321.md?p=g-1) does not show a significant difference from the extent of absorption of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application when administered at the same dose of the active ingredient under similar experimental conditions in either a single dose or multiple doses and the difference from the approved [new animal drug](/usc/21/321.md?p=v) in the rate of absorption of the [drug](/usc/21/321.md?p=g-1) is intentional, is reflected in its proposed [labeling](/usc/21/321.md?p=m), is not essential to the attainment of effective [drug](/usc/21/321.md?p=g-1) concentrations in use, and is considered scientifically insignificant for the [drug](/usc/21/321.md?p=g-1) in attaining the intended purposes of its use and preserving human [food](/usc/21/321.md?p=f) safety; or
        - (III) in any case in which the [Secretary](/usc/21/321.md?p=d) determines that the measurement of the rate and extent of absorption or excretion of the [new animal drug](/usc/21/321.md?p=v) in biological fluids is inappropriate or impractical, an appropriate acute pharmacological effects test or other test of the [new animal drug](/usc/21/321.md?p=v) and, when deemed scientifically necessary, of the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application in the species to be tested or in an appropriate animal model does not show a significant difference between the [new animal drug](/usc/21/321.md?p=v) and such approved [new animal drug](/usc/21/321.md?p=v) when administered at the same dose under similar experimental conditions.

        If the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application for a [new animal drug](/usc/21/321.md?p=v) under [subsection (n)](#n) is approved for use in more than one animal species, the bioequivalency information described in subclauses [(I)](#c-2-H-ii-I), [(II)](#c-2-H-ii-II), and [(III)](#c-2-H-ii-III) shall be obtained for one species, or if the [Secretary](/usc/21/321.md?p=d) deems appropriate based on scientific principles, shall be obtained for more than one species. The [Secretary](/usc/21/321.md?p=d) may prescribe the dose to be used in determining bioequivalency under subclause [(I)](#c-2-H-ii-I), [(II)](#c-2-H-ii-II), or [(III)](#c-2-H-ii-III). To assure that the residues of the [new animal drug](/usc/21/321.md?p=v) will be consistent with the established tolerances for the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application under [subsection (b)(2)](#b-2) upon the expiration of the withdrawal period contained in the application for the [new animal drug](/usc/21/321.md?p=v), the [Secretary](/usc/21/321.md?p=d) shall require bioequivalency data or residue depletion studies of the [new animal drug](/usc/21/321.md?p=v) or such other data or studies as the [Secretary](/usc/21/321.md?p=d) considers appropriate based on scientific principles. If the [Secretary](/usc/21/321.md?p=d) requires one or more residue studies under the preceding sentence, the [Secretary](/usc/21/321.md?p=d) may not require that the assay methodology used to determine the withdrawal period of the [new animal drug](/usc/21/321.md?p=v) be more rigorous than the methodology used to determine the withdrawal period for the approved [new animal drug](/usc/21/321.md?p=v) referred to in the application. If such studies are required and if the approved [new animal drug](/usc/21/321.md?p=v), referred to in the application for the [new animal drug](/usc/21/321.md?p=v) for which such studies are required, is approved for use in more than one animal species, such studies shall be conducted for one species, or if the [Secretary](/usc/21/321.md?p=d) deems appropriate based on scientific principles, shall be conducted for more than one species.

  - (3) If the patent information described in [subsection (b)(1)](#b-1) could not be filed with the submission of an application under [subsection (b)(1)](#b-1) because the application was filed before the patent information was required under [subsection (b)(1)](#b-1) or a patent was issued after the application was approved under such subsection, the holder of an approved application shall file with the [Secretary](/usc/21/321.md?p=d) the patent number and the expiration date of any patent which claims the [new animal drug](/usc/21/321.md?p=v) for which the application was filed or which claims a method of using such [drug](/usc/21/321.md?p=g-1) and with respect to which a claim of patent infringement could reasonably be asserted if a [person](/usc/21/321.md?p=e) not [licensed](/usc/21/360eee.md?p=9) by the owner engaged in the manufacture, use, or sale of the [drug](/usc/21/321.md?p=g-1). If the holder of an approved application could not file patent information under [subsection (b)(1)](#b-1) because it was not required at the time the application was approved, the holder shall file such information under this subsection not later than 30 days after November 16, 1988, and if the holder of an approved application could not file patent information under [subsection (b)(1)](#b-1) because no patent had been issued when an application was filed or approved, the holder shall file such information under this subsection not later than 30 days after the date the patent involved is issued. Upon the submission of patent information under this subsection, the [Secretary](/usc/21/321.md?p=d) shall publish it.
  - (4) A [drug](/usc/21/321.md?p=g-1) manufactured in a pilot or other small facility may be used to demonstrate the safety and effectiveness of the [drug](/usc/21/321.md?p=g-1) and to obtain approval for the [drug](/usc/21/321.md?p=g-1) prior to manufacture of the [drug](/usc/21/321.md?p=g-1) in a larger facility, unless the [Secretary](/usc/21/321.md?p=d) makes a determination that a full scale production facility is necessary to ensure the safety or effectiveness of the [drug](/usc/21/321.md?p=g-1).
- (d) **Grounds for refusing application; approval of application; factors; “substantial evidence” defined; combination drugs—**
  - (1) If the [Secretary](/usc/21/321.md?p=d) finds, after due notice to the applicant in accordance with [subsection (c)](#c) and giving him an opportunity for a hearing, in accordance with said subsection, that—
    - (A) the investigations, reports of which are required to be submitted to the [Secretary](/usc/21/321.md?p=d) pursuant to [subsection (b)](#b), do not include adequate tests by all methods reasonably applicable to show whether or not such [drug](/usc/21/321.md?p=g-1) is [safe](/usc/21/321.md?p=u) for use under the conditions prescribed, recommended, or suggested in the proposed [labeling](/usc/21/321.md?p=m) thereof;
    - (B) the results of such tests show that such [drug](/usc/21/321.md?p=g-1) is unsafe for use under such conditions or do not show that such [drug](/usc/21/321.md?p=g-1) is [safe](/usc/21/321.md?p=u) for use under such conditions;
    - (C) the methods used in, and the facilities and controls used for, the manufacture, processing, and packing of such [drug](/usc/21/321.md?p=g-1) are inadequate to preserve its identity, strength, quality, and purity;
    - (D) upon the basis of the information submitted to him as part of the application, or upon the basis of any other information before him with respect to such [drug](/usc/21/321.md?p=g-1), he has insufficient information to determine whether such [drug](/usc/21/321.md?p=g-1) is [safe](/usc/21/321.md?p=u) for use under such conditions;
    - (E) evaluated on the basis of the information submitted to him as part of the application and any other information before him with respect to such [drug](/usc/21/321.md?p=g-1), there is a lack of substantial evidence that the [drug](/usc/21/321.md?p=g-1) will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in the proposed [labeling](/usc/21/321.md?p=m) thereof;
    - (F) upon the basis of information submitted to the [Secretary](/usc/21/321.md?p=d) as part of the application or any other information before the [Secretary](/usc/21/321.md?p=d) with respect to such [drug](/usc/21/321.md?p=g-1), any use prescribed, recommended, or suggested in [labeling](/usc/21/321.md?p=m) proposed for such [drug](/usc/21/321.md?p=g-1) will result in a residue of such [drug](/usc/21/321.md?p=g-1) in excess of a tolerance found by the [Secretary](/usc/21/321.md?p=d) to be [safe](/usc/21/321.md?p=u) for such [drug](/usc/21/321.md?p=g-1);
    - (G) the application failed to contain the patent information prescribed by [subsection (b)(1)](#b-1);
    - (H) based on a fair evaluation of all material facts, such [labeling](/usc/21/321.md?p=m) is false or misleading in any particular; or
    - (I) such [drug](/usc/21/321.md?p=g-1) induces cancer when ingested by man or animal or, after tests which are appropriate for the evaluation of the safety of such [drug](/usc/21/321.md?p=g-1), induces cancer in man or animal, except that the foregoing provisions of this subparagraph shall not apply with respect to such [drug](/usc/21/321.md?p=g-1) if the [Secretary](/usc/21/321.md?p=d) finds that, under the conditions of use specified in proposed [labeling](/usc/21/321.md?p=m) and reasonably certain to be followed in practice (i) such [drug](/usc/21/321.md?p=g-1) will not adversely affect the animals for which it is intended, and (ii) no residue of such [drug](/usc/21/321.md?p=g-1) will be found (by methods of examination prescribed or approved by the [Secretary](/usc/21/321.md?p=d) by regulations, which regulations shall not be subject to subsections [(c)](#c), [(d)](#d), and [(h)](#h)), in any edible portion of such animals after slaughter or in any [food](/usc/21/321.md?p=f) yielded by or derived from the living animals;

    he shall issue an order refusing to approve the application. If, after such notice and opportunity for hearings, the [Secretary](/usc/21/321.md?p=d) finds that subparagraphs [(A)](#d-1-A) through [(I)](#d-1-I) do not apply, he shall issue an order approving the application.

  - (2) In determining whether such [drug](/usc/21/321.md?p=g-1) is [safe](/usc/21/321.md?p=u) for use under the conditions prescribed, recommended, or suggested in the proposed [labeling](/usc/21/321.md?p=m) thereof, the [Secretary](/usc/21/321.md?p=d) shall consider, among other relevant factors, (A) the probable consumption of such [drug](/usc/21/321.md?p=g-1) and of any substance formed in or on [food](/usc/21/321.md?p=f) because of the use of such [drug](/usc/21/321.md?p=g-1), (B) the cumulative effect on man or animal of such [drug](/usc/21/321.md?p=g-1), taking into account any chemically or pharmacologically related substance, (C) safety factors which in the opinion of experts, qualified by scientific training and experience to evaluate the safety of such [drugs](/usc/21/321.md?p=g-1), are appropriate for the use of animal experimentation data, and (D) whether the conditions of use prescribed, recommended, or suggested in the proposed [labeling](/usc/21/321.md?p=m) are reasonably certain to be followed in practice. Any order issued under this subsection refusing to approve an application shall [state](/usc/21/321.md?p=a-1) the findings upon which it is based.
  - (3) As used in this section, the term “substantial evidence” means evidence consisting of one or more adequate and well controlled investigations, such as—
    - (A) a study in a target species;
    - (B) a study in laboratory animals;
    - (C) any field investigation that may be required under this section and that meets the requirements of [subsection (b)(3)](#b-3) if a presubmission conference is requested by the applicant;
    - (D) a bioequivalence study; or
    - (E) an in vitro study;

    by experts qualified by scientific training and experience to evaluate the effectiveness of the [drug](/usc/21/321.md?p=g-1) involved, on the basis of which it could fairly and reasonably be concluded by such experts that the [drug](/usc/21/321.md?p=g-1) will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in the [labeling](/usc/21/321.md?p=m) or proposed [labeling](/usc/21/321.md?p=m) thereof.

  - (4) In a case in which an animal [drug](/usc/21/321.md?p=g-1) contains more than one active ingredient, or the [labeling](/usc/21/321.md?p=m) of the [drug](/usc/21/321.md?p=g-1) prescribes, recommends, or suggests use of the [drug](/usc/21/321.md?p=g-1) in combination with one or more other animal [drugs](/usc/21/321.md?p=g-1), and the active ingredients or [drugs](/usc/21/321.md?p=g-1) intended for use in the combination have previously been separately approved pursuant to an application submitted under [subsection (b)(1)](#b-1) for particular uses and conditions of use for which they are intended for use in the combination—
    - (A) the [Secretary](/usc/21/321.md?p=d) shall not issue an order under paragraph [(1)(A)](#d-1-A), [(1)(B)](#d-1-B), or [(1)(D)](#d-1-D) refusing to approve the application for such combination on human [food](/usc/21/321.md?p=f) safety grounds unless the [Secretary](/usc/21/321.md?p=d) finds that the application fails to establish that—
      - (i) none of the active ingredients or [drugs](/usc/21/321.md?p=g-1) intended for use in the combination, respectively, at the longest withdrawal time of any of the active ingredients or [drugs](/usc/21/321.md?p=g-1) in the combination, respectively, exceeds its established tolerance; or
      - (ii) none of the active ingredients or [drugs](/usc/21/321.md?p=g-1) in the combination interferes with the methods of analysis for another of the active ingredients or [drugs](/usc/21/321.md?p=g-1) in the combination, respectively;
    - (B) the [Secretary](/usc/21/321.md?p=d) shall not issue an order under paragraph [(1)(A)](#d-1-A), [(1)(B)](#d-1-B), or [(1)(D)](#d-1-D) refusing to approve the application for such combination on target animal safety grounds unless the [Secretary](/usc/21/321.md?p=d) finds that—
      - (i)
        - (I) there is a substantiated scientific issue, specific to one or more of the active ingredients or animal [drugs](/usc/21/321.md?p=g-1) in the combination, that cannot adequately be evaluated based on information contained in the application for the combination (including any investigations, studies, or tests for which the applicant has a right of reference or use from the [person](/usc/21/321.md?p=e) by or for whom the investigations, studies, or tests were conducted); or
        - (II) there is a scientific issue raised by target animal observations contained in studies submitted to the [Secretary](/usc/21/321.md?p=d) as part of the application; and
      - (ii) based on the [Secretary](/usc/21/321.md?p=d)’s evaluation of the information contained in the application with respect to the issues identified in clauses [(i)(I)](#d-4-B-i-I) and (II), paragraph [(1)(A)](#d-1-A), (B), or (D) apply;
    - (C) except in the case of a combination that contains a nontopical antibacterial ingredient or animal [drug](/usc/21/321.md?p=g-1), the [Secretary](/usc/21/321.md?p=d) shall not issue an order under [paragraph (1)(E)](#d-1-E) refusing to approve an application for a combination animal [drug](/usc/21/321.md?p=g-1) intended for use other than in [animal feed](/usc/21/321.md?p=w) or drinking water unless the [Secretary](/usc/21/321.md?p=d) finds that the application fails to demonstrate that—
      - (i) there is substantial evidence that any active ingredient or animal [drug](/usc/21/321.md?p=g-1) intended only for the same use as another active ingredient or animal [drug](/usc/21/321.md?p=g-1) in the combination makes a contribution to labeled effectiveness;
      - (ii) each active ingredient or animal [drug](/usc/21/321.md?p=g-1) intended for at least one use that is different from all other active ingredients or animal [drugs](/usc/21/321.md?p=g-1) used in the combination provides appropriate concurrent use for the intended target population; or
      - (iii) where based on scientific information the [Secretary](/usc/21/321.md?p=d) has reason to believe the active ingredients or animal [drugs](/usc/21/321.md?p=g-1) may be physically incompatible or have disparate dosing regimens, such active ingredients or animal [drugs](/usc/21/321.md?p=g-1) are physically compatible or do not have disparate dosing regimens; and
    - (D) the [Secretary](/usc/21/321.md?p=d) shall not issue an order under [paragraph (1)(E)](#d-1-E) refusing to approve an application for a combination animal [drug](/usc/21/321.md?p=g-1) intended for use in [animal feed](/usc/21/321.md?p=w) or drinking water unless the [Secretary](/usc/21/321.md?p=d) finds that the application fails to demonstrate that—
      - (i) there is substantial evidence that any active ingredient or animal [drug](/usc/21/321.md?p=g-1) intended only for the same use as another active ingredient or animal [drug](/usc/21/321.md?p=g-1) in the combination makes a contribution to the labeled effectiveness;
      - (ii) each of the active ingredients or animal [drugs](/usc/21/321.md?p=g-1) intended for at least one use that is different from all other active ingredients or animal [drugs](/usc/21/321.md?p=g-1) used in the combination provides appropriate concurrent use for the intended target population;
      - (iii) where a combination contains more than one nontopical antibacterial ingredient or animal [drug](/usc/21/321.md?p=g-1), there is substantial evidence that each of the nontopical antibacterial ingredients or animal [drugs](/usc/21/321.md?p=g-1) makes a contribution to the labeled effectiveness, except that for purposes of this clause, antibacterial ingredient or animal [drug](/usc/21/321.md?p=g-1) does not include the ionophore or arsenical classes of animal [drugs](/usc/21/321.md?p=g-1); or
      - (iv) where based on scientific information the [Secretary](/usc/21/321.md?p=d) has reason to believe the active ingredients or animal [drugs](/usc/21/321.md?p=g-1) intended for use in drinking water may be physically incompatible, such active ingredients or animal [drugs](/usc/21/321.md?p=g-1) intended for use in drinking water are physically compatible.
  - (5) In reviewing an application that proposes a change to add an intended use for a [minor use](/usc/21/321.md?p=pp) or a [minor species](/usc/21/321.md?p=oo) to an approved [new animal drug](/usc/21/321.md?p=v) application, the [Secretary](/usc/21/321.md?p=d) shall reevaluate only the relevant information in the approved application to determine whether the application for the [minor use](/usc/21/321.md?p=pp) or [minor species](/usc/21/321.md?p=oo) can be approved. A decision to approve the application for the [minor use](/usc/21/321.md?p=pp) or [minor species](/usc/21/321.md?p=oo) is not, implicitly or explicitly, a reaffirmation of the approval of the original application.
- (e) **Withdrawal of approval; grounds; immediate suspension upon finding imminent hazard to health of man or animals—**
  - (1) The [Secretary](/usc/21/321.md?p=d) shall, after due notice and opportunity for hearing to the applicant, issue an order withdrawing approval of an application filed pursuant to [subsection (b)](#b) with respect to any [new animal drug](/usc/21/321.md?p=v) if the [Secretary](/usc/21/321.md?p=d) finds—
    - (A) that experience or scientific data show that such [drug](/usc/21/321.md?p=g-1) is unsafe for use under the conditions of use upon the basis of which the application was approved or the condition of use [authorized](/usc/21/360eee.md?p=2) under [subsection (a)(4)(A)](#a-4-A);
    - (B) that new evidence not contained in such application or not available to the [Secretary](/usc/21/321.md?p=d) until after such application was approved, or tests by new methods, or tests by methods not deemed reasonably applicable when such application was approved, evaluated together with the evidence available to the [Secretary](/usc/21/321.md?p=d) when the application was approved, shows that such [drug](/usc/21/321.md?p=g-1) is not shown to be [safe](/usc/21/321.md?p=u) for use under the conditions of use upon the basis of which the application was approved or that subparagraph (I) of paragraph (1) of [subsection (d)](#d) applies to such [drug](/usc/21/321.md?p=g-1);
    - (C) on the basis of new information before him with respect to such [drug](/usc/21/321.md?p=g-1), evaluated together with the evidence available to him when the application was approved, that there is a lack of substantial evidence that such [drug](/usc/21/321.md?p=g-1) will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in the [labeling](/usc/21/321.md?p=m) thereof;
    - (D) the patent information prescribed by [subsection (c)(3)](#c-3) was not filed within 30 days after the receipt of written notice from the [Secretary](/usc/21/321.md?p=d) specifying the failure to file such information;
    - (E) that the application contains any untrue statement of a material fact; or
    - (F) that the applicant has made any changes from the standpoint of safety or effectiveness beyond the variations provided for in the application unless he has supplemented the application by filing with the [Secretary](/usc/21/321.md?p=d) adequate information respecting all such changes and unless there is in effect an approval of the supplemental application. The supplemental application shall be treated in the same manner as the original application.

    If the [Secretary](/usc/21/321.md?p=d) (or in his absence the officer acting as [Secretary](/usc/21/321.md?p=d)) finds that there is an imminent hazard to the health of man or of the animals for which such [drug](/usc/21/321.md?p=g-1) is intended, he may suspend the approval of such application immediately, and give the applicant prompt notice of his action and afford the applicant the opportunity for an expedited hearing under this subsection; but the authority conferred by this sentence to suspend the approval of an application shall not be delegated.

  - (2) The [Secretary](/usc/21/321.md?p=d) may also, after due notice and opportunity for hearing to the applicant, issue an order withdrawing the approval of an application with respect to any [new animal drug](/usc/21/321.md?p=v) under this section if the [Secretary](/usc/21/321.md?p=d) finds—
    - (A) that the applicant has failed to establish a system for maintaining required rec­ords, or has repeatedly or deliberately failed to maintain such records or to make required reports in accordance with a regulation or order under [subsection (l)](#l), or the applicant has refused to permit access to, or copying or [verification](/usc/21/360eee.md?p=28) of, such records as required by [paragraph (2)](#e-2) of such subsection;
    - (B) that on the basis of new information before him, evaluated together with the evidence before him when the application was approved, the methods used in, or the facilities and controls used for, the manufacture, processing, and packing of such [drug](/usc/21/321.md?p=g-1) are inadequate to assure and preserve its identity, strength, quality, and purity and were not made adequate within a reasonable time after receipt of written notice from the [Secretary](/usc/21/321.md?p=d) specifying the matter complained of; or
    - (C) that on the basis of new information before him, evaluated together with the evidence before him when the application was approved, the [labeling](/usc/21/321.md?p=m) of such [drug](/usc/21/321.md?p=g-1), based on a fair evaluation of all material facts, is false or misleading in any particular and was not corrected within a reasonable time after receipt of written notice from the [Secretary](/usc/21/321.md?p=d) specifying the matter complained of.
  - (3) Any order under this subsection shall [state](/usc/21/321.md?p=a-1) the findings upon which it is based.
- (f) **Revocation of order refusing, withdrawing or suspending approval of application—** Whenever the [Secretary](/usc/21/321.md?p=d) finds that the facts so require, he shall revoke any previous order under subsection [(d)](#d), [(e)](#e), or [(m)](#m), or [section 360ccc(c)](/usc/21/360ccc.md?p=c), (d), or (e) of this title refusing, withdrawing, or suspending approval of an application and shall approve such application or reinstate such approval, as may be appropriate.
- (g) **Service of orders—** Orders of the [Secretary](/usc/21/321.md?p=d) issued under this section, or [section 360ccc of this title](/usc/21/360ccc.md) (other than orders issuing, amending, or repealing regulations) shall be served (1) in [person](/usc/21/321.md?p=e) by any officer or employee of the [department](/usc/21/321.md?p=c) designated by the [Secretary](/usc/21/321.md?p=d) or (2) by mailing the order by registered mail or by certified mail addressed to the applicant or respondent at his last known address in the records of the [Secretary](/usc/21/321.md?p=d).
- (h) **Appeal from order—** An appeal may be taken by the applicant from an order of the [Secretary](/usc/21/321.md?p=d) refusing or withdrawing approval of an application filed under subsection [(b)](#b) or [(m)](#m) of this section. The provisions of subsection (h) of [section 355 of this title](/usc/21/355.md) shall govern any such appeal.
- (i) **Publication in Federal Register; effective date and revocation or suspension of regulation—** When a [new animal drug](/usc/21/321.md?p=v) application filed pursuant to [subsection (b)](#b) or [section 360ccc of this title](/usc/21/360ccc.md) is approved, the [Secretary](/usc/21/321.md?p=d) shall by notice, which upon publication shall be effective as a regulation, publish in the Federal Register the name and address of the applicant and the conditions and indications of use of the [new animal drug](/usc/21/321.md?p=v) covered by such application, including any tolerance and withdrawal period or other use restrictions and, if such [new animal drug](/usc/21/321.md?p=v) is intended for use in [animal feed](/usc/21/321.md?p=w), appropriate purposes and conditions of use (including special [labeling](/usc/21/321.md?p=m) requirements and any requirement that an [animal feed](/usc/21/321.md?p=w) bearing or containing the [new animal drug](/usc/21/321.md?p=v) be limited to use under the professional supervision of a [licensed](/usc/21/360eee.md?p=9) veterinarian) applicable to any [animal feed](/usc/21/321.md?p=w) for use in which such [drug](/usc/21/321.md?p=g-1) is approved, and such other information, upon the basis of which such application was approved, as the [Secretary](/usc/21/321.md?p=d) deems necessary to assure the [safe](/usc/21/321.md?p=u) and effective use of such [drug](/usc/21/321.md?p=g-1). Upon withdrawal of approval of such [new animal drug](/usc/21/321.md?p=v) application or upon its suspension or upon failure to renew a conditional approval under [section 360ccc of this title](/usc/21/360ccc.md), the [Secretary](/usc/21/321.md?p=d) shall forthwith revoke or suspend, as the case may be, the regulation published pursuant to this [subsection (i)](#i) insofar as it is based on the approval of such application.
- (j) **Exemption of drugs for research; discretionary and mandatory conditions—** To the extent consistent with the public health, the [Secretary](/usc/21/321.md?p=d) shall promulgate regulations for exempting from the operation of this section [new animal drugs](/usc/21/321.md?p=v), and [animal feeds](/usc/21/321.md?p=w) bearing or containing [new animal drugs](/usc/21/321.md?p=v), intended solely for investigational use by experts qualified by scientific training and experience to investigate the safety and effectiveness of animal [drugs](/usc/21/321.md?p=g-1). Such regulations may, in the discretion of the [Secretary](/usc/21/321.md?p=d), among other conditions relating to the protection of the public health, provide for conditioning such exemption upon the establishment and maintenance of such records, and the making of such reports to the [Secretary](/usc/21/321.md?p=d), by the [manufacturer](/usc/21/360hh.md?p=3) or the [sponsor](/usc/21/360fff.md?p=8) of the investigation of such article, of data (including but not limited to analytical reports by investigators) obtained as a result of such investigational use of such article, as the [Secretary](/usc/21/321.md?p=d) finds will enable him to evaluate the safety and effectiveness of such article in the event of the filing of an application pursuant to this section. Such regulations, among other things, shall set forth the conditions (if any) upon which animals treated with such articles, and any [products](/usc/21/360eee.md?p=13) of such animals (before or after slaughter), may be marketed for [food](/usc/21/321.md?p=f) use.
- (k) **Food containing new animal drug considered unadulterated while approval of application for such drug is effective—** While approval of an application for a [new animal drug](/usc/21/321.md?p=v) is effective, a [food](/usc/21/321.md?p=f) shall not, by reason of bearing or containing such [drug](/usc/21/321.md?p=g-1) or any substance formed in or on the [food](/usc/21/321.md?p=f) because of its use in accordance with such application (including the conditions and indications of use prescribed pursuant to [subsection (i)](#i)), be considered adulterated within the meaning of clause (1) of [section 342(a) of this title](/usc/21/342.md?p=a).
- (l) **Records and reports; required information; regulations and orders; examination of data; access to records—**
  - (1) In the case of any [new animal drug](/usc/21/321.md?p=v) for which an approval of an application filed pursuant to [subsection (b)](#b) or [section 360ccc of this title](/usc/21/360ccc.md) is in effect, the applicant shall establish and maintain such records, and make such reports to the [Secretary](/usc/21/321.md?p=d), of data relating to experience, including experience with uses [authorized](/usc/21/360eee.md?p=2) under [subsection (a)(4)(A)](#a-4-A), and other data or information, received or otherwise obtained by such applicant with respect to such [drug](/usc/21/321.md?p=g-1), or with respect to [animal feeds](/usc/21/321.md?p=w) bearing or containing such [drug](/usc/21/321.md?p=g-1), as the [Secretary](/usc/21/321.md?p=d) may by general regulation, or by order with respect to such application, prescribe on the basis of a finding that such records and reports are necessary in order to enable the [Secretary](/usc/21/321.md?p=d) to determine, or facilitate a determination, whether there is or may be ground for invoking [subsection (e)](#e) or [subsection (m)(4)](#m-4) of this section. Such regulation or order shall provide, where the [Secretary](/usc/21/321.md?p=d) deems it to be appropriate, for the examination, upon request, by the [persons](/usc/21/321.md?p=e) to whom such regulation or order is applicable, of similar information received or otherwise obtained by the [Secretary](/usc/21/321.md?p=d).
  - (2) Every [person](/usc/21/321.md?p=e) required under this subsection to maintain records, and every [person](/usc/21/321.md?p=e) in charge or custody thereof, shall, upon request of an officer or employee designated by the [Secretary](/usc/21/321.md?p=d), permit such officer or employee at all reasonable times to have access to and copy and [verify](/usc/21/360eee.md?p=28) such records.
  - (3)
    - (A) In the case of each [new animal drug](/usc/21/321.md?p=v) described in [paragraph (1)](#l-1) that contains an antimicrobial active ingredient, the [sponsor](/usc/21/360fff.md?p=8) of the [drug](/usc/21/321.md?p=g-1) shall submit an annual report to the [Secretary](/usc/21/321.md?p=d) on the amount of each antimicrobial active ingredient in the [drug](/usc/21/321.md?p=g-1) that is sold or distributed for use in [food](/usc/21/321.md?p=f)-producing animals, including information on any distributor-labeled [product](/usc/21/360eee.md?p=13).
    - (B) Each report under this paragraph shall specify the amount of each antimicrobial active ingredient—
      - (i) by container size, strength, and dosage form;
      - (ii) by quantities distributed domestically and quantities exported; and
      - (iii) by dosage form, including, for each such dosage form, a listing of the target animals, indications, and production classes that are specified on the approved [label](/usc/21/321.md?p=k) of the [product](/usc/21/360eee.md?p=13).
    - (C) Each report under this paragraph shall—
      - (i) be submitted not later than March 31 each year;
      - (ii) cover the period of the preceding calendar year; and
      - (iii) include separate information for each month of such calendar year.
    - (D) The [Secretary](/usc/21/321.md?p=d) may share information reported under this paragraph with the Antimicrobial Resistance Task Force established under [section 247d–5 of title 42](/usc/42/247d–5.md).
    - (E) The [Secretary](/usc/21/321.md?p=d) shall make summaries of the information reported under this paragraph publicly available, except that—
      - (i) the summary data shall be reported by antimicrobial class, and no class with fewer than 3 distinct [sponsors](/usc/21/360fff.md?p=8) of approved applications shall be independently reported; and
      - (ii) the data shall be reported in a manner consistent with protecting both national security and confidential business information.

  - (2) Within 90 days after the filing of an application pursuant to [paragraph (1)](#m-1), or such additional period as may be agreed upon by the [Secretary](/usc/21/321.md?p=d) and the applicant, the [Secretary](/usc/21/321.md?p=d) shall (A) issue an order approving the application if the [Secretary](/usc/21/321.md?p=d) then finds that none of the grounds for denying approval specified in [paragraph (3)](#m-3) applies, or (B) give the applicant notice of an opportunity for a hearing before the [Secretary](/usc/21/321.md?p=d) under [paragraph (3)](#m-3) on the question whether such application is approvable. The procedure governing such a hearing shall be the procedure set forth in the last two sentences of [subsection (c)(1)](#c-1).
  - (3) If the [Secretary](/usc/21/321.md?p=d), after due notice to the applicant in accordance with [paragraph (2)](#m-2) and giving the applicant an opportunity for a hearing in accordance with such paragraph, finds, on the basis of information submitted to the [Secretary](/usc/21/321.md?p=d) as part of the application, on the basis of a preapproval inspection, or on the basis of any other information before the [Secretary](/usc/21/321.md?p=d)—
    - (A) that the application is incomplete, false, or misleading in any particular;
    - (B) that the methods used in, and the facilities and controls used for, the manufacture, processing, and packing of such [animal feed](/usc/21/321.md?p=w) are inadequate to preserve the identity, strength, quality, and purity of the [new animal drug](/usc/21/321.md?p=v) therein; or
    - (C) that the facility manufactures [animal feeds](/usc/21/321.md?p=w) bearing or containing [new animal drugs](/usc/21/321.md?p=v) in a manner that does not accord with the specifications for manufacture or [labels](/usc/21/321.md?p=k) [animal feeds](/usc/21/321.md?p=w) bearing or containing [new animal drugs](/usc/21/321.md?p=v) in a manner that does not accord with the conditions or indications of use that are published pursuant to [subsection (i)](#i) or an index listing pursuant to [section 360ccc–1(e) of this title](/usc/21/360ccc–1.md?p=e),
