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 › § 360ff–1
Makes it easier to develop and get approval for genetically targeted drugs and variant protein drugs that treat rare, serious, or life‑threatening illnesses in specific patient groups (including groups with different gene mutations). It also encourages using scientific tools like surrogate endpoints and biomarkers. The Secretary may allow a drug sponsor to use data they already developed (or data they have a legal right to use) and data that supported earlier approved drug applications when applying for these kinds of drugs. Genetically targeted drug: a drug for a rare, serious illness that changes a gene’s function or its product and uses genetically targeted technology. Genetically targeted technology: non‑replicating nucleic acid or similar compounds with common chemistry aimed at treating subgroups of the same disease. Variant protein targeted drug: a drug for a rare, serious illness that changes the function of a mutated gene product and targets patient subgroups. This does not change the Secretary’s approval authority or the rules about evidence or data‑referencing as they were before December 13, 2016.
