SUPPLEMENTARY INFORMATION:

I. Background

Except with respect to the limited exemption provided by the Federal Food, Drug, and Cosmetic Act (FD&C Act) described in the following paragraph, statutory provisions applicable to manufactured animal drugs under the FD&C Act also apply to animal drugs compounded from bulk drug substances.

Sections 512(a)(4) and (5) of the FD&C Act (21 U.S.C. 360b(a)(4) and (5)) provide a limited exemption from certain requirements for compounded animal drugs made from already FDA-approved animal or human drugs. Such use is considered an extralabel use. The FD&C Act provides that a compounded drug is exempt from the approval requirements in section 512(a) of the FD&C Act and requirements for adequate directions for use in section 502(f)(1) of the FD&C Act (21 U.S.C. 352(f)(1)) if it meets the conditions set out in the statute and the extralabel use regulations at 21 CFR part 530.

Elsewhere in this issue of the Federal Register, FDA is announcing the availability of draft guidance for industry #256 entitled “Compounding Animal Drugs from Bulk Drug Substances” (GFI #256).[1] The draft guidance describes circumstances under which FDA, based on our current understanding of the risks of animal drugs compounded from bulk drug substances, does not intend to take action against pharmacists in either State-licensed pharmacies or Federal facilities, or veterinarians, who compound animal drugs from bulk drug substances. If the draft guidance is finalized, FDA would not intend to take action under sections 512(a), 501(a)(5), 502(f), and 501(a)(2)(B) of the FD&C Act so long as such compounding is done under the approach described in draft GFI #256.

II. Nominating Bulk Drug Substances

In a Federal Register notice published on May 19, 2015 (80 FR 28622), FDA invited all interested parties to nominate bulk drug substances for inclusion on a list of bulk drug substances that could be used by outsourcing facilities registered under the FD&C Act to compound animal drugs under the conditions described in draft GFI #230, “Compounding Animal Start Printed Page 64082Drugs from Bulk Drug Substances” (announced in the same issue of the Federal Register (80 FR 28624)) (the 2015 request for nominations notice).

Although that draft guidance was subsequently withdrawn in November 2017, FDA received over 30 comments containing nominations for multiple bulk drug substances in response to the 2015 request for nominations notice. FDA's approach for evaluating whether to include a bulk drug substance on the list described in the 2015 request for nominations notice is substantially the same as the approach below for including a bulk drug substance on the list of bulk drug substances for compounding certain animal drugs without a patient specific prescription (i.e., office stock) for use in nonfood-producing animals or antidotes for food-producing animals in accordance with FDA's draft guidance for industry #256 (the List). As a result, CVM intends to include on the List the eight bulk drug substances that FDA previously determined met the approach set out in the now withdrawn 2015 draft guidance. To the extent these substances and conditions of use meet the approach of the final guidance, FDA intends to include them on the List when the draft guidance is finalized.

  • Apomorphine hydrochloride—Indication: For the induction of emesis in dogs. Dosage form: 6.25 mg subconjunctival tablets, 3.125-6.25 milligrams/milliliters (mg/ml) subconjunctival solution, and 2.5 mg/ml injectable solution.
  • Cisapride—Indication: For the management of gastrointestinal motility disorders in cats. Dosage form: 2.5 & 5 mg oral tablets, 2.5 & 5 mg oral capsules, 5-10 mg/ml oral suspension.
  • Dipyrone—Indication: For the treatment of severe, acute fever in dogs suffering from Shar-Pei Fever. Dosage form: 250 mg/ml and 500 mg/ml injectable solution.
  • Guaifenesin—Indication: For muscle relaxation in the horse during anesthetic induction and/or surgery. Dosage form: 50 g soluble powder to be reconstituted into a solution for IV infusion with the addition of 500 ml (10%) or 1000 ml (5%) sterile diluent.
  • Miconazole nitrate—Indication: For the treatment of fungal keratitis in horses. Dosage form: 1% or 2% miconazole nitrate ophthalmic solution or ophthalmic ointment.
  • Potassium bromide—Indication: For initiation of treatment for seizures in dogs. Dosage form: 250 mg/ml oral solution.
  • Tacrolimus—Indication: For treatment of dogs with keratoconjunctivitis sicca that is non-responsive to cyclosporine. Dosage form: 0.01-0.03% tacrolimus ophthalmic drops.
  • Metronidazole benzoate—Indication: For the treatment of feline inflammatory bowel disease in cats. Dosage form: 80 mg/ml oral suspension.

The docket used to collect the previous nominations is now closed for comment. However, FDA is establishing a new public docket so that interested parties can nominate bulk drug substances, re-nominate bulk drug substances with adequate supporting information that were previously nominated without adequate supporting information, or comment on the eight previously nominated bulk drug substances that FDA intends to add to the List when the draft guidance is finalized. This docket will remain open indefinitely so that individuals may nominate and comment on bulk drug substances at any time.

When will FDA include a bulk drug substance on the list of bulk drug substances for compounding office stock drugs for use in nonfood-producing animals or antidotes for food-producing animals?

FDA intends to include a bulk drug substance on the List when:

1. There is no marketed FDA-approved, conditionally approved, or indexed animal drug that can be used as labeled to treat the condition;

2. There is no marketed FDA-approved animal or human drug that could be used in an extralabel manner under section 512(a)(4) or (a)(5) of the FD&C Act and part 530 to treat the condition;

3. The drug cannot be compounded from a legally marketed FDA-approved, conditionally approved, or indexed animal or human drug;

4. Immediate treatment with the compounded drug is necessary to avoid animal suffering or death; and

5. FDA has not identified a significant safety concern specific to the use of the bulk drug substance to compound animal drugs (under the listed conditions and limitations).

For bulk drug substances for compounding drugs intended for use as antidotes in food-producing animals in addition to the above:

6. There is sufficient scientific information for the veterinarian to determine appropriate withdrawal, withholding, or discard time(s) for meat, milk, eggs, or any food which might be derived from the treated animal(s).

How do I submit a nomination for the list?

You may submit nominations and comments to the docket through https://www.regulations.gov. The information to support nominations can be uploaded as attachments to your comment. The docket number is FDA-2018-N-4626.

You may submit written submissions to the Dockets Management Staff (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852. All submissions must include the Docket No. FDA-2018-N-4626 for “List of Bulk Drug Substances for Compounding Office Stock Drugs for Use in Nonfood-Producing Animals or Antidotes for Food-Producing Animals.”

What information should I submit with the nomination?

You may nominate specific bulk drug substances for inclusion on the List. Each bulk drug substance should be submitted to the docket as its own, separate nomination. Submissions to the docket containing more than one bulk drug substance will not be considered an adequate nomination and will not be reviewed. In addition, nominations will only be evaluated if they are for specific substances that meet the definition of a bulk drug substance.[2] Nominated substances that do not meet this definition will not be evaluated for inclusion on the List.

For FDA to evaluate a bulk drug substance for inclusion on the List, you should submit the following information about the bulk drug substance and the compounded animal drug in the nomination:

1. Confirmation That the Nominated Substance is a Bulk Drug Substance: A Start Printed Page 64083statement that the nominated substance meets the definition of bulk drug substance.

2. Description of the Bulk Drug Substance:

(a) Chemical name(s);

(b) common name(s);

(c) chemical grade (e.g., USP-NF, ACS, etc.);

(d) description of the strength, stability, purity; and

(e) how the bulk drug substance is supplied (e.g., powder, liquid).

3. Description of the Animal Drugs That Will be Compounded With the Bulk Drug Substance:

(a) dosage form(s) into which the bulk drug substance will be compounded (e.g., capsule, tablet, suspension);

(b) strength(s) of the compounded drug(s); and

(c) intended route(s) of administration of the compounded drug(s).

4. Information Requested for FDA to Evaluate Bulk Drug Substances for Inclusion on the List:

(a) the species and condition(s) that the drug to be compounded with the nominated bulk drug substance is intended to treat;

(b) a bibliography of scientific literature containing safety and effectiveness data for the drug compounded using the nominated substance;

(c) a list of animal drugs, if any, that are FDA-approved, conditionally approved, or indexed for the condition(s) in the species that the drug compounded with the nominated substance is intended to address;

(d) if there are marketed FDA-approved, conditionally approved, or indexed drugs that address the same condition(s) in the same species, an explanation, supported by relevant scientific literature or other evidence, of why a compounded drug is necessary (e.g., why the FDA-approved, conditionally approved, or indexed drug is not suitable for a particular animal population);

(e) confirmation, using supporting evidence, that there are no marketed FDA-approved animal or human drugs that could be prescribed in an extralabel manner under section 512(a)(4) and (a)(5) of the FD&C Act and 21 CFR part 530 to treat the condition(s) in the species that the drug compounded with the nominated substance is intended to address;

(f) If the bulk drug substance is an active ingredient in a marketed FDA-approved, conditionally approved, or indexed animal or human drug, an explanation, supported by appropriate scientific data or information, of why the animal drug cannot be compounded from the marketed FDA-approved, conditionally approved, or indexed animal or human drug.

(g) An explanation, supported by relevant scientific literature or other evidence, of why the animal drug to be compounded with the nominated bulk drug substance must be available to the veterinarian for immediate treatment to avoid animal suffering or death. Nominations should include specific information documenting that animal suffering or death will result if treatment is delayed until a compounded animal drug can be obtained pursuant to a prescription for an individually identified animal; and

(h) A description of any human user or animal safety concerns associated with use of the nominated bulk drug substance or finished compounded drug for the condition(s) in the species that the compounded drug is intended to address. If there are concerns, an explanation, supported by scientific literature or other evidence, of why the concerns should not preclude inclusion of that bulk drug substance on the List.

(i) For compounded drugs intended for use as antidotes to treat toxicoses in food-producing animals, relevant scientific literature or other evidence that demonstrates that the prescribing veterinarian has a basis for determining appropriate withdrawal, withholding, or discard time(s) for meat, milk, eggs, or any food which might be derived from the treated animal(s).

Footnotes

2.  FDA regulations define “bulk drug substance” and “active pharmaceutical ingredient” as “any substance that is intended for incorporation into a finished drug product and is intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease, or to affect the structure or any function of the body.” The terms do not include intermediates used in the synthesis of the substance. 21 CFR 207.1. “Active ingredient” is defined as “any component that is intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease, or to affect the structure or any function of the body of man or other animals. The term includes those components that may undergo chemical change in the manufacture of the drug product and be present in the drug product in a modified form intended to furnish the specified activity or effect.” 21 CFR 210.3(b)(7). Any component other than an active ingredient is an “inactive ingredient” (21 CFR 210.3(b)(8)). Inactive ingredients used in compounded drug products commonly include flavorings, dyes, diluents, or other excipients. In addition, for purposes of evaluating nominations, FDA considers bulk chemicals used to make antidotes intended to treat toxicoses in animals to be bulk drug substances.
