Orphan Drug Legislation
Orphan drugs generally follow the same regulatory development path as any other pharmaceutical product, in which testing focuses on pharmacokinetics and pharmacodynamics, dosing, stability, safety and efficacy. However, some statistical burdens are lessened in an effort to maintain development momentum. For 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.
Since the market for any drug with such a limited application scope would, by definition, be small and thus largely unprofitable, government intervention is often required to motivate a manufacturer to address the need for an orphan drug. Critics of free market enterprise often cite this as a failure of free market economic systems.
The intervention by government on behalf of orphan drug development can take a variety of forms:
- Tax incentives.
- Enhanced patent protection and marketing rights.
- Clinical research financial subsidization.
- Creating a government-run enterprise to engage in research and development (see Crown corporation).

Famous quotes containing the words orphan, drug and/or legislation:
“A man should not go where he cannot carry his whole sphere or society with him,Mnot bodily, the whole circle of his friends, but atmospherically. He should preserve in a new company the same attitude of mind and reality of relation, which his daily associates draw him to, else he is shorn of his best beams, and will be an orphan in the merriest club.”
—Ralph Waldo Emerson (1803–1882)
“Whoever grows angry amid troubles applies a drug worse than the disease and is a physician unskilled about misfortunes.”
—Sophocles (497–406/5 B.C.)
“Being offended is the natural consequence of leaving one’s home. I do not like after- shave lotion, adults who roller-skate, children who speak French, or anyone who is unduly tan. I do not, however, go around enacting legislation and putting up signs.”
—Fran Lebowitz (b. 1950)
