David M. Fox

David M. Fox is a leading authority on the regulation of prescription and over-the-counter drugs, biological products, combination products, and controlled substances.

He began his Food and Drug Administration (FDA) career in its Office of the Chief Counsel as assistant chief counsel for enforcement and associate chief counsel for drugs. During his FDA tenure and in private practice, David has been deeply involved in precedent-setting disputes between pioneer and generic drug sponsors under the Hatch-Waxman Act. In 2012, he founded biosimilarslawblog.com, a forum for commenting on the emerging field of biosimilars. He has also published leading texts on drug-device combination products and the regulation of controlled substances by FDA and Drug Enforcement Administration (DEA).

David advises management teams, from start-ups to the largest global pharmaceutical and biotechnology companies, on matters before the FDA and DEA. He is closely integrated with funding sources for the industry and is frequently retained as a strategic advisor on assessing the value of life sciences assets. He is known for his collaborative approach to complex regulatory issues and has successfully resolved numerous differences between sponsors and staff at FDA on products that raise novel issues.

Regularly recognized at the top of the administrative law bar, David was named the 2015 LMG Life Sciences Regulatory Lawyer of the Year. He is also routinely listed at the top of his field in leading industry publications, including Chambers USA America's Leading Lawyers, Who's Who Legal, Washington D.C. Super Lawyers, PLC Life Sciences, and Washingtonian's Top Lawyers.

David previously led our Pharmaceutical and Biotechnology Practice Group and now serves on the firm's Global Life Sciences Management Team.

"[R]egarded as one of the brightest all-round stars among the younger generation of FDA lawyers."
