Impax Laboratories Confirms Patent Challenge Relating to INTUNIVTM, 4 mg
December 03 2010 - 5:00PM
Business Wire
Impax Laboratories, Inc. (NASDAQ: IPXL) today confirms
that it has initiated a challenge of patents listed by Shire
Development Inc. in connection with INTUNIVTM (guanfacine
hydrochloride), 4 mg.
Impax filed its Abbreviated New Drug Application (ANDA)
containing a paragraph IV certification for a generic version of
INTUNIV™ with the U.S. Food & Drug Administration
(FDA). Following receipt of the notice from the FDA that
Impax’s ANDA had been accepted for filing, Impax notified the New
Drug Application holder and patent owners of its paragraph IV
certification.
On December 2, 2010, Shire LLC, Supernus Pharmaceuticals, Inc.,
Amy F.T. Arnsten, Pasko Rakic, and Richard D. Hunt filed suit for
patent infringement against Impax in the United States District
Court for the Northern District of California. This action formally
initiates the patent challenge process under the Hatch-Waxman
Act.
Once the ANDA is approved by FDA, Global Pharmaceuticals,
Impax’s generic division, will commercialize the products.
INTUNIV™ is indicated for the treatment of Attention Deficit
Hyperactivity Disorder. According to Wolters Kluwer Health, U.S.
sales of INTUNIV™, 4 mg, were approximately $14 million for the
twelve-month period ending September 30, 2010.
