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 › § 360bb
A drug maker can ask the Secretary to call their medicine a treatment for a rare disease or condition. The request must come before the company files the drug approval or license application. The Secretary will decide if the drug is being or will be studied for a rare disease. A rare disease means it affects fewer than 200,000 people in the United States, or it affects more but sales are not expected to pay back the cost of developing the drug. The Secretary uses the facts that exist when the request is made. If the Secretary gives the rare-disease designation, the maker must meet two conditions. If the drug is approved or licensed, the maker must tell the Secretary at least one year before they stop making it. If the drug is still in preclinical or clinical studies and not yet approved or licensed, the maker must tell the Secretary if they decide to stop seeking approval or a license. The Secretary must make the designation public and create rules to carry out this process.
