§360cc Protection for drugs for rare diseases or conditions

Title 21 › Chapter CHAPTER 9— - FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter SUBCHAPTER V— - DRUGS AND DEVICES › Part Part B— - Drugs for Rare Diseases or Conditions › § 360cc

Last updated Apr 18, 2026|Official source

Summary

Gives a drug for a rare disease a 7-year period of exclusivity after the Secretary approves it or issues a license. During that 7-year period the Secretary may only allow the same drug for the same approved use if the exclusivity holder cannot supply enough medicine (after being notified and allowed to respond) or if the holder gives written permission. If a company wants exclusivity for a drug that is basically the same as an already approved drug, the company must prove the new drug is clinically superior. "Clinically superior" means a clear health advantage: better effectiveness, better safety, or a major help to patient care. This rule applies to drugs approved or licensed after Aug 18, 2017. The Secretary can make rules, must tell sponsors why a drug was designated, and must publish a summary if exclusivity is granted for clinical superiority. "Approved use or indication" means the use approved or licensed for the rare disease.

(a)Except as provided in subsection (b), if the Secretary—
(1)approves an application filed pursuant to section 355 of this title, or
(2)issues a license under section 262 of title 42
(b)During the 7-year period described in subsection (a) for an approved application under section 355 of this title or license under section 262 of title 42, the Secretary may approve an application or issue a license for a drug that is otherwise the same, as determined by the Secretary, as the already approved drug for the same approved use or indication for which such 7-year period applies to such already approved or licensed drug if—
(1)the Secretary finds, after providing the holder of exclusive approval or licensure notice and opportunity for the submission of views, that during such period the holder of the exclusive approval or licensure cannot ensure the availability of sufficient quantities of the drug to meet the needs, relating to the approved use or indication, of persons with the disease or condition for which the drug was designated; or
(2)the holder provides the Secretary in writing the consent of such holder for the approval of other applications or the issuance of other licenses before the expiration of such seven-year period.
(c)(1)If a sponsor of a drug that is designated under section 360bb of this title and is otherwise the same, as determined by the Secretary, as an already approved or licensed drug is seeking exclusive approval or exclusive licensure described in subsection (a) for the same use or indication for which the already approved or licensed drug was approved or licensed, the Secretary shall require such sponsor, as a condition of such exclusive approval or licensure, to demonstrate that such drug is clinically superior to any already approved or licensed drug that is the same drug.
(2)For purposes of paragraph (1), the term “clinically superior” with respect to a drug means that the drug provides a significant therapeutic advantage over and above an already approved or licensed drug in terms of greater efficacy, greater safety, or by providing a major contribution to patient care.
(3)This subsection applies to any drug designated under section 360bb of this title for which an application was approved under section 355 of this title or licensed under section 262 of title 42 after August 18, 2017, regardless of the date on which such drug was designated under section 360bb of this title.
(d)The Secretary may promulgate regulations for the implementation of subsection (c). Beginning on August 18, 2017, until such time as the Secretary promulgates regulations in accordance with this subsection, the Secretary may apply any definitions set forth in regulations that were promulgated prior to such date, to the extent such definitions are not inconsistent with the terms of this section, as amended by such Act.
(e)To assist sponsors in demonstrating clinical superiority as described in subsection (c), the Secretary—
(1)upon the designation of any drug under section 360bb of this title, shall notify the sponsor of such drug in writing of the basis for the designation, including, as applicable, any plausible hypothesis offered by the sponsor and relied upon by the Secretary that the drug is clinically superior to a previously approved drug; and
(2)upon granting exclusive approval or licensure under subsection (a) on the basis of a demonstration of clinical superiority as described in subsection (c), shall publish a summary of the clinical superiority findings.
(f)In this section, the term “approved use or indication” means the use or indication approved under section 355 of this title or licensed under section 262 of title 42 for a drug designated under section 360bb of this title for a rare disease or condition.
