Lethal injection opinion from DOJ OLC threatens FDA's claims-based interpretation of 'intended use'
USA | 10 July 2019

In a recent opinion, the Office of Legal Counsel (OLC) in the US Department of Justice concluded that an article intended to effectuate capital punishment by a state or the federal government is not subject to regulation by the Food and Drug Administration (FDA) under the Federal Food, Drug and Cosmetic Act. The OLC's opinion appears to have been issued as a result of litigation involving the FDA's obligation to block the entry of misbranded and unapproved drugs used under state lethal injection protocols.

FDA continues scrutiny of direct-to-consumer genetic testing
USA | 13 January 2016

The Food and Drug Administration (FDA) recently released three untitled letters from the Office of In Vitro Diagnostics and Radiological Health to clinical laboratories offering direct-to-consumer genetic tests, and a report of case studies purporting to provide public health evidence for FDA oversight of all laboratory-developed tests. These developments signal that the FDA remains focused on direct-to-consumer tests and willing to assert authority over them.

FDA loses Amarin litigation; court grants preliminary relief
USA | 16 September 2015

In a widely anticipated recent ruling in the ongoing Amarin litigation against the US Food and Drug Administration (FDA), the judge granted Amarin's general and specific requests for relief. This ruling is of major significance for FDA-regulated manufacturers as it addresses and rejects the FDA's frequently articulated rationale that it must be allowed to regulate truthful, non-misleading off-label speech.

New MDDS guidance reduces regulatory hurdles for developers
USA | 09 July 2014

The Food and Drug Administration has issued draft guidance announcing that it does not intend to enforce compliance with the regulatory controls that apply to software medical device data systems, medical image storage devices or medical image communications devices, due to the low risk they pose to patients and the importance they play in advancing digital health.

FDA issues draft guidance on medical device reporting
USA | 14 August 2013

The Food and Drug Administration recently announced the availability of draft guidance, Medical Device Reporting for Manufacturers, which, when final, will supersede the 1997 version. The draft addresses specific questions about the reporting and record-keeping requirements for device-related adverse events.

Second Circuit rejects regulation of off-label promotion as misbranding
USA | 19 December 2012

In a widely anticipated ruling the US Court of Appeals for the Second Circuit recently reversed the conviction of pharmaceutical sales representative Alfred Caronia for misbranding under the Federal Food, Drug and Cosmetic Act, based on alleged off-label promotion. The court agreed with Caronia that the government's prosecution had been based solely on speech promoting off-label uses.
