What Are Interchangeable Biological Products?
A biological product is interchangeable if it is biosimilar to the reference product and is expected to produce the same clinical result as the reference product in any given patient. A biosimilar product that is deemed to be interchangeable by the FDA means the biosimilar product can be substituted for the reference product by a pharmacist without consulting the prescriber. The specific requirements for substitution vary by state.

What Is Advertising Litigation?
Advertising litigation is defined as the legal area that covers false or deceptive advertising cases. Lawsuits may be brought by government agencies or corporate competitors based on the Lanham Act—a law that specifically deals with false advertising. The Act outlines how an advertisement can be deemed false. The Federal Trade Commission (FTC) has the ability to file lawsuits to halt deceptive advertising claims. The U.S. Food and Drug Administration may also pursue advertising litigation against violators of government regulations. Companies may be called on to substantiate their advertising claims, whether these are made in print or online.

In the product liability context, general causation is the legal and scientific determination of whether the product in question has the inherent capability to cause the alleged injury under certain circumstances. Establishment of general causation is a critical aspect of a plaintiff’s case, and typically requires scientific evidence, such as epidemiology or toxicology, and expert testimony to establish a causal connection between the product’s design, manufacturing, or warnings and the injury or injuries at issue. As contrasted to specific causation, the focus in a general causation inquiry is on whether the product or exposure, as a general matter, can cause the type of injury claimed by the plaintiff. A general causation inquiry does not assess any facts unique to a particular plaintiff.
