Amarin Ruling Solidifies Off-Label Marketing Options But Raises Questions About False Claims Act Enforcement Action

The Southern District of New York recently ruled in Amarin Pharma, Inc. et al. v. Food and Drug Administration, et al. that a drug company may engage in "truthful and non-misleading speech" about off-label uses of an approved drug without the threat of a misbranding action under the Federal Food, Drug, and Cosmetic Act. No. 1:15-cv-03588 (S.D.N.Y., Aug. 7, 2015). This important decision—which arose out of Amarin's constitutional challenge seeking to make certain statements about unapproved uses of a triglyceride-lowering drug, Vascepa—builds on recent Second Circuit precedent that allows drug makers more regulatory latitude, at minimum in the Second Circuit, to provide truthful and non-misleading scientific information about unapproved uses for their products. However, the ruling also serves as a reminder of potential False Claims Act (FCA) liability associated with off-label marketing of pharmaceuticals and devices.

Amarin filed its complaint against the Food and Drug Administration (FDA) after the company received a Complete Response Letter (CRL) from the FDA in connection with its application for approval of a new indication. The CRL indicated that, while clinical studies revealed that Vascepa reduced triglyceride levels, based on its data review, the FDA advised that additional clinical data would be needed before it could approve the drug for additional uses beyond the original approval for "very" high levels of triglycerides. Despite the fact that Amarin sought to make truthful and non-misleading statements about its product to "sophisticated healthcare professionals," including the physicians who joined Amarin in the lawsuit, the FDA concluded there was insufficient support for approval of the supplemental application for a new indication and stated that any communications about off-label uses of Vascepa could result in enforcement action.

While the FDA described Amarin's First Amendment claims as a "frontal assault on the framework for new drug approval that Congress created in 1962," the court rejected all of the government's counterarguments. Relying on the Second Circuit's decision in United States v. Caronia, 703 F.3d 149 (2d Cir. 2012), the court held that Amarin could engage in the following activity:
