Nitrosamine Impurities FDA 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.

FDA Revises Policies and Procedures for Prioritization of ANDAs in New MAPP

On January 30, 2020, the U.S. Food & Drug Administration (FDA) issued a new Manual of Policies & Procedures (MAPP) concerning how it will prioritize internal review of abbreviated new drug applications (ANDAs), amendments and supplements.

Whether a submission qualifies for priority designation can mean a substantial difference in approval time. As the FDA explains, it “may grant an ANDA submission either a shorter review goal date or an expedited review” if the submission satisfies a public health priority (or prioritization factor) described in the MAPP.

FDA Adds Useful Information to the ANDA Paragraph IV Certifications List for Better Transparency and Predictability

The U.S. Food and Drug Administration took another step to implement its Drug Competition Action Plan on June 18, 2019, by updating the information provided in the Paragraph IV Certifications List. The updated list will provide greater transparency regarding Paragraph IV certifications and potential exclusivities. That transparency will in turn lead to greater predictability for generic manufacturers regarding the potential timing of approval for their ANDAs and the potential degree of competition. The additional information will also give the public better insight into the status of generic regulatory exclusivities and the potential future availability of lower-cost generic alternatives for specific drug products.

FDA Issues Draft Guidances for Prior Approval Supplements and Amendments / Easily Correctable Deficiencies Under GDUFA

The Generic Drug User Fee Amendments of 2012 (GDUFA) were signed into law on July 9, 2012, in an effort “to speed access to safe and effective generic drugs to the public and reduce costs to industry.” In July 2014, the U.S. Food and Drug Administration issued two draft Guidances for Industry: one relating to Prior Approval Supplements Under GDUFA and one relating to Amendments and Easily Correctable Deficiencies Under GDUFA.

FDA Releases Guidance for Industry on ANDAs: Stability Testing of Drug Substances and Products, Questions and Answers

The U.S. Food and Drug Administration (FDA) recently published a new Guidance for Industry, titled ANDAs: Stability Testing of Drug Substances and Products, Questions and Answers, which provides answers to questions from public comments received on the draft Guidance for Industry on ANDAs: Stability Testing of Drug Substances and Products (“FDA stability guidance”) that was published in the Federal Register on September 25, 2012. It also incorporates comments received on the same draft, which were previously published in the Federal Register on August 27, 2013.

Successful Use of Inter Partes Review to Cancel Claims Asserted in Parallel Litigation

By Vicki G. Norton, Siegfried J.W. Ruppert, and Michael Swit

In a trio of March 6, 2014 inter partes review (IPR) decisions, the Patent Trial and Appeal Board (PTAB) canceled patent claims related to next generation DNA sequencing technology, after Illumina, Inc. countered Columbia University’s patent infringement suit by successfully petitioning for IPR of claims in three of five of Columbia’s patents-in-suit.

The decisions illustrate the utility of the new IPR process before the PTAB, implemented under the America Invents Act (AIA), as a parallel venue in which patent litigation defendants can challenge the patentability of claims asserted against them in litigation, more expeditiously and less costly than in court proceedings.
