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 maker can ask the Secretary to label a medicine as for a rare disease or condition. The request must come before the company files a marketing application or a license. The Secretary will grant the label if the drug is being or will be studied for a rare disease and any future approval or license would be for that disease. The request must say the company agrees to let the Secretary announce the designation to the public. A “rare disease or condition” means it affects fewer than 200,000 people in the United States, or it affects more but selling the drug in the U.S. would not likely pay back development costs. The Secretary decides this based on facts when the request is made. If the drug is approved, the company must give at least one year’s notice before stopping production. If it is still in testing and the company stops pursuing approval, it must tell the Secretary. The Secretary must publish the designation and set up rules for how this process works.
