FDA Issues New Nitrosamine Impurities Guidance

By Alan Klein, Patrick Gallagher and Michael Fox

On August 4, 2023, the FDA issued a new Guidance to the pharmaceutical industry relating to large molecule drugs left unaddressed in its earlier nitrosamine Guidance publications. (Access the complete Guidance or the abbreviated version.)

Reacting to considerable input from the pharmaceutical industry, both brand and generic, following the agency’s Federal Register request for and receipt of extensive comments on these issues, including scientific data furnished to the agency by NDA and ANDA sponsors over the past year and a half, FDA has now provided drug manufacturers with critical guidelines for conforming their products to what the agency has determined to be safe nitrosamine exposure limits for patients. This comes on the heels of setting similar exposure limits for these products late last month by the European Union’s chief drug regulator, the European Medicines Agency. In its current Guideline, FDA has ranked impacted prescription drugs into 5 categories depending upon their carcinogenic potency, with “1” being the most potent, and “5” the least. Instructing the industry on their responsibility to minimize or eliminate nitrosamine impurities in their products to the extent feasible, the agency has extended the timeline for this task to August 2025, recognizing the complexity of this process and the need to avoid recalls and market disruptions of widely prescribed and important medications.

Order Requires Disclosure of 3rd Party Funding Information in Zantac MDL

On April 3, 2020, the United States District Court for the Southern District of Florida issued an order in the pending Zantac multidistrict litigation (”MDL”) requiring disclosure of funding arrangements and funding documentation between plaintiffs’ counsel and third-party litigation financiers. This order represents some increased traction in favor of arguments seeking to require disclosure of third-party funding arrangements in MDLs.

The Zantac MDL, In re Zantac (Ranitidine) Prods. Liab. Litig., MDL No. 2924, was originally formed by the Judicial Panel for Multidistrict Litigation on February 6, 2020. The plaintiffs sued various defendants, including manufacturer Sanofi and its distributors, alleging that the active ingredient in the heartburn medication Zantac breaks down to form a carcinogen that caused personal injuries. Included in the MDL are also six putative classes of consumers who sought refunds and economic damages based on their purchase of Zantac. Due to a number of actions already pending in the Southern District of Florida, the Panel transferred the remaining actions to that court to be assigned to the Honorable Robin L. Rosenberg.

Why Reformers Want Disclosure Of 3rd-Party MDL Funding

It is no secret that third-party litigation funding, or TPLF, has become an increasingly common practice. One area particularly affected by this trend is that of mass tort actions and multidistrict litigations, where funding is now more than ever being utilized to finance voluminous and prolonged proceedings.

While courts have historically been reluctant to require disclosure of funding agreements and information, precedent suggests that different approaches may be warranted in the MDL context because of considerations unique to those proceedings — including potential for bias, distortions of control and decision-making as between litigants and funders, and conflicts of interest between funders and the judiciary.

Against this backdrop, advocates of disclosure have taken a proactive role in seeking further changes to rules of discovery and disclosure to address these issues. Litigants should be aware of these emerging efforts toward change, and the reasons underlying them, as the use of litigation funding continues to rise.

Much of Oklahoma’s $572 Million Opioid Case Likely to Be Replicated Elsewhere, But Unique Cause of Action May Not

On August 26, 2019, Cleveland County, Oklahoma, District Judge Thad Balkman delivered his highly anticipated ruling in the state of Oklahoma’s lawsuit against certain pharmaceutical companies responsible for manufacturing and marketing prescription opioid medications. Because the other pharmaceutical companies named in the state’s case settled with the Attorney General’s Office earlier this year, Johnson & Johnson and its subsidiary Janssen Pharmaceuticals remained the primary subjects of the evidence at trial and the focus of the attention surrounding Judge Balkman’s then-forthcoming ruling.

As Judge Balkman stated in the published judgment, the defendants knowingly and misleadingly marketed their highly addictive prescription opioids, and by doing so caused harm for which the state could seek redress, as their “actions annoyed, injured, or endangered the comfort, repose, health or safety of Oklahomans.”
