A 505(b)(2) New Drug Application (NDA) is a submission to the Food and Drug Administration (FDA) for approval to market a drug in the USA. It differs from a ‘stand-alone’ NDA in that some of the data on which the applicant relies to demonstrate safety and efficacy have been obtained from publicly available sources rather than from the applicant’s own studies. The applicant typically proposes to market a drug that is based on an approved reference product but modified in its formulation or uses. A 505(b)(2) NDA also differs from an Abbreviated New Drug Application (ANDA) for approval of a generic drug in that the applicant’s product need not be a duplicate of the reference listed drug. The 505(b)(2) pathway may be said to lie part-way between the ‘stand-alone’ NDA and generics pathways, offering a unique combination of advantages to developers. It facilitates the modification of drugs to address unmet medical needs. The 505(b)(2) application pathway accounts for about half of all new drug approvals in the USA.

Medicines for the prevention, diagnosis, or treatment of rare diseases have become known as ‘orphan drugs’ because of their commercial unattractiveness. Development of such products is successfully encouraged through incentives offered by regulatory authorities. To qualify for important incentives, the sponsor of a drug must gain ‘orphan designation’ for its use in an indication. This module describes the requirements for orphan designation and how to apply for it in the USA and the European Economic Area.
