Title 21 › Chapter 9— FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter V— DRUGS AND DEVICES › Part B— Drugs for Rare Diseases or Conditions › § 360bb
A drug company or sponsor can ask the Secretary (the head of the health agency) to officially label a drug as for a rare disease or condition. The request must come before they file the drug approval or biologics license application. A disease is “rare” if it affects fewer than 200,000 people in the United States, or if it affects more but the maker cannot reasonably expect to recover development costs from U.S. sales. The agency decides based on the facts on the date the request is made. If the drug gets approved or licensed, the maker must tell the Secretary at least one year before stopping production. If approval or a license hasn’t been granted and trials are happening, the maker must notify the Secretary if they decide to stop pursuing approval. The designation will be made public, and the Secretary must create rules for how the process will work.
