The U.S. Food and Drug Administration (“FDA”) to grant 5-year New Chemical Entity (“NCE”)
On February 23, 2007, after reviewing the requisite clinical studies submitted on behalf of VYVANSE, the FDA determined that VYVANSE qualified as an NCE within the meaning of the governing statutes and regulations. As an NCE, VYVANSE is entitled to 5-year market exclusivity.
The FDA therefore appropriately refused to file the Abbreviated New Drug Application (“ANDA”) submitted by Actavis Elizabeth, LLC for generic lisdexamfetamine dimesylate. On February 24, 2009, Actavis sued the FDA in the District Court of the District of Columbia challenging the NCE decision.
Shire is pleased that on March 4, 2010, following the extensive briefing of the parties and an oral hearing, the Court upheld the FDA’s decision (and reaffirmation) that VYVANSE is entitled to 5-year market exclusivity. The Court correctly determined that FDA’s actions complied with federal administrative law standards as a reasonable exercise of the agency’s scientific expertise.
The five-year exclusivity period for VYVANSE expires on February 23, 2012, and precludes generic manufacturers from submitting an ANDA to FDA until that time, or until February 23, 2011 should a generic applicant challenge the United States patents covering Vyvanse, which remain in effect until June 29, 2023.
