In an effort to incentivize the development of certain fixed-combination drug products, the Food and Drug Administration (FDA) recently issued draft guidance revising its interpretation of the 5-year New Chemical Entity exclusivity provisions of the Federal Food, Drug and Cosmetic Act (FD&C Act).

Sections 505(c)(3)(E) and 505(j)(5)(F) of the FD&C Act provide the holder of an approved New Drug Application with the benefit of limited protection from certain competition (e.g., generic competition) in the marketplace.  In particular, newly approved drug products that contain an active ingredient that has not been previously approved by FDA (a so-called “new chemical entity”) are eligible for 5-years of New Chemical Entity (NCE) exclusivity and, with one exception, during such 5-year exclusivity period, third party applications referencing the newly-approved drug cannot be submitted to FDA.

Fixed-combination drug products are combinations of two or more active ingredients in a single dosage form or drug product.  FDA has historically interpreted the 5-year NCE exclusivity provisions of the FD&C Act such that fixed-combination drug products that contained a previously-approved drug product were not eligible for 5-year NCE exclusivity, irrespective of whether such fixed-combination drug product contained a new chemical entity.

Based on FDA’s recognition of the increasing prevalence of fixed-combination drug products in certain therapeutic areas (e.g., cancer and infectious diseases, such as HIV) and the role that such combination products play in optimizing adherence to dosing regimens and improving patient outcomes, FDA has revised its interpretation of the 5-year NCE exclusivity provisions.  As a result of FDA’s revised interpretation, a 5-year NCE exclusivity determination will be made on the basis of each active ingredient in a drug product, such that a drug product that includes a new chemical entity will be eligible for 5-year NCE exclusivity, regardless of whether that drug substance is approved alone or in a fixed-combination.  FDA is soliciting comments in response to its draft guidance until April 25, 2014.
