Clinical Glossary: Orphan Drug
Orphan Drug
Definition: A designation of the FDA to indicate a therapy developed to treat a rare disease (one which afflicts a U.S. population of less than 200,000 people). Because there are few financial incentives for drug companies to develop therapies for diseases that afflict so few people, the U.S. government offers additional incentives to drug companies (i.e. tax advantages and extended marketing exclusivity) that develop these drugs. |
