Medical Definition of orphan drug. : a drug that is not developed or marketed because its extremely limited use (as in the treatment of a rare disease) makes it unprofitable.
The EU's definition of an orphan condition is broader than that of the USA, in that it also covers some tropical diseases that are primarily found in developing nations. Orphan drug status granted by the European Commission gives marketing exclusivity in the EU for 10 years after approval.The EU's legislation is administered by the Committee on Orphan Medicinal Products of the European Medicines Agency (EMA).or example, orphan drug regulations generally acknowledge the fact that it may not be possible to test 1,000 patients in a phase III clinical trial, as fewer than that number may be afflicted with the disease in question.
