Drug Competition Enhancement Act

This bill prohibits product hopping by drug manufacturers and authorizes the Federal Trade Commission (FTC) to enforce this prohibition.

Generally, product hopping describes a situation where, when the patents on a reference drug (or biological product) expire, the manufacturer switches to a follow-on product that is covered by a later-expiring patent. Under this bill, a follow-on product is a modified version of the reference drug that has an indication (what the drug is used for) that is identical or substantively similar to an indication of the reference drug.

The bill establishes a presumption that product hopping has occurred when a reference drug manufacturer, after receiving notice that the Food and Drug Administration has received an application to market a competing generic (or biosimilar) version, takes certain actions such as withdrawing the reference drug from the market and selling a follow-on product.

A drug manufacturer may rebut these presumptions by demonstrating that its conduct was not intended to limit competition.
