Orphan
Drugs
The term "orphan drug" refers to a product that
treats a rare disease affecting fewer than 200,000 Americans. The
Orphan Drug Act was signed into law on January 4, 1983. Since the
Orphan Drug Act passed, over 100 orphan drugs and biological
products have been brought to market.
The intent of the Orphan Drug Act is to stimulate the
research, development, and approval of products that treat rare
diseases. This mission is accomplished through several
mechanisms:
- Sponsors are granted seven years of marketing exclusivity
after approval of its orphan drug product.
- Sponsors also are granted tax incentives for clinical
research they have undertaken.
- FDA's Office
of Orphan Products Development coordinates research
study design assistance for sponsors of drugs for rare
diseases [Notice: This link will take you outside
the CDER web site].
- The Office of Orphan Products Development also encourages
sponsors to conduct open protocols, allowing patients to
be added to ongoing studies.
- Grant funding is available to defray costs of qualified
clinical testing expenses incurred in connection with the
development of orphan products.
