§360ccc Conditional approval of new animal drugs for minor use and minor species and certain new animal drugs

Title 21 › Chapter CHAPTER 9— - FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter SUBCHAPTER V— - DRUGS AND DEVICES › Part Part F— - New Animal Drugs for Minor Use and Minor Species › § 360ccc

Last updated Apr 6, 2026|Official source

Summary

Allows a person to ask the Secretary (FDA) for a conditional OK to market a new animal drug in two cases: the drug is for a minor use or a minor species, or the drug treats a serious or life‑threatening condition or fills an unmet health need and proving full effectiveness would need especially hard studies. The FDA had to give more details about the second case by September 30, 2019. You cannot ask for conditional approval for a drug from a transgenic animal, file a duplicate application for the same drug and use, or use someone else’s application or data. Also, drugs that are antimicrobials cannot use the serious‑disease path. Starting October 1, 2018, applications must be sent electronically. An application must include safety reports, enough data to show a reasonable expectation of effectiveness, a conditional dose, estimates of how much the drug will be needed and sold each year, and a promise to finish full effectiveness studies within 5 years. The FDA has 180 days after filing to either issue a one‑year conditional approval or offer a hearing. Conditional approval lasts 1 year and can be renewed yearly up to 4 more years (a 5‑year total) unless the FDA finds problems. The FDA can refuse or withdraw conditional approval if new full approval is granted to someone else who can supply enough drug, if safety or effectiveness concerns arise, or if the applicant fails to show progress toward full approval. The drug label must say it is conditionally approved and that full proof of effectiveness is still pending, and it must include the application number. You cannot add new uses to a conditionally approved application. Applicants must submit all materials needed for full approval at least 180 days before the conditional approval ends or the conditional approval will stop. “Transgenic animal” means an animal whose genome was intentionally changed in a lab (including its offspring), but not an animal changed only by selective breeding. The FDA’s authority to give conditional approval for drugs that are not for a minor use or minor species ends on October 1, 2028. After that date the FDA cannot accept new applications under that path, but it can keep working on drugs that were already conditionally approved and can accept full approval applications for those drugs until October 1, 2032.

(ii)a new animal drug not intended for a minor use or minor species—
(I)that is intended to treat a serious or life-threatening disease or condition or addresses an unmet animal or human health need; and
(II)for which the Secretary determines that a demonstration of effectiveness would require a complex or particularly difficult study or studies.
(B)The Secretary shall, not later than September 30, 2019, issue guidance or regulations further clarifying the criteria specified in subparagraph (A)(ii).
(C)An application under this paragraph shall comply in all respects with the provisions of section 360b of this title except for subsections (a)(4), (b)(2), (c)(1), (c)(2), (c)(3), (d)(1), (e), (h), and (n) of such section unless otherwise stated in this section, and any additional provisions of this section.

(2)The applicant shall submit to the Secretary as part of an application for the conditional approval of a new animal drug—
(A)all information necessary to meet the requirements of section 360b(b)(1) of this title except section 360b(b)(1)(A) of this title;
(B)full reports of investigations which have been made to show whether or not such drug is safe under section 360b(d) of this title (including, for an antimicrobial new animal drug, with respect to antimicrobial resistance) and there is a reasonable expectation of effectiveness for use;

(2)the information submitted to the Secretary as part of the application and any other information before the Secretary with respect to such drug, is insufficient to show that there is a reasonable expectation that the drug will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in the proposed labeling thereof; or
(3)another person has received approval under section 360b of this title for the same drug in the same dosage form for the same intended use, and that person is able to assure the availability of sufficient quantities of the drug to meet the needs for which the drug is intended;

(ii)the quantity of the drug that has been distributed is consistent with the conditionally approved intended use and conditions of use, unless there is adequate explanation that ensures that the drug is only used for its intended purpose; or
(iii)the same drug in the same dosage form for the same intended use has not received approval under section 360b of this title, or if such a drug has been approved, that the holder of the approved application is unable to assure the availability of sufficient quantities of the drug to meet the needs for which the drug is intended; or

(2)The Secretary shall, after due notice and opportunity for an informal hearing to the applicant, issue an order withdrawing conditional approval of an application filed pursuant to subsection (a) if the Secretary finds that—
(A)any of the provisions of section 360b(e)(1)(A) through (B) or (D) through (F) of this title are applicable; or
(B)on the basis of new information before the Secretary with respect to such drug, evaluated together with the evidence available to the Secretary when the application was conditionally approved, that there is not a reasonable expectation that such drug will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in the labeling thereof.

Statutory Notes and Related Subsidiaries

Findings Pub. L. 108–282, title I, § 102(a), Aug. 2, 2004, 118 Stat. 891, provided that: “Congress makes the following findings: “(1) There is a severe shortage of approved new animal drugs for use in minor species. “(2) There is a severe shortage of approved new animal drugs for treating animal diseases and conditions that occur infrequently or in limited geographic areas. “(3) Because of the small market shares, low-profit margins involved, and capital investment required, it is generally not economically feasible for new animal drug applicants to pursue approvals for these species, diseases, and conditions. “(4) Because the populations for which such new animal drugs are intended may be small and conditions of animal management may vary widely, it is often difficult to design and conduct studies to establish drug safety and effectiveness under traditional new animal drug approval processes. “(5) It is in the public interest and in the interest of animal welfare to provide for special procedures to allow the lawful use and marketing of certain new animal drugs for minor species and minor uses that take into account these special circumstances and that ensure that such drugs do not endanger animal or public health. “(6) Exclusive marketing rights for clinical testing expenses have helped encourage the development of ‘orphan’ drugs for human use, and comparable incentives should encourage the development of new animal drugs for minor species and minor uses.”
