HAYWARD, Calif.--(BUSINESS WIRE)--
Impax Laboratories, Inc. (NASDAQ: IPXL) today confirms that it
has initiated a challenge of the patents listed in the Orange Book in
connection with Fentora® (fentanyl buccal tablets, 100 mcg, 200 mcg, 400
mcg, 600 mcg and 800 mcg).
Impax filed its Abbreviated New Drug Application (ANDA) containing a
paragraph IV certification for a generic version of Fentora® with
the U.S. Food & Drug Administration (FDA). Following receipt of the
notice from FDA that Impax’s ANDA had been accepted for filing, Impax
notified the New Drug Application holder and patent owner of its
paragraph IV certification.
On November 18, 2011, Cephalon, Inc. and CIMA Labs, Inc. filed suit for
patent infringement against Impax Laboratories, Inc. in the District of
Delaware. 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, intends to commercialize the product.
Fentora® is used to treat "breakthrough" cancer pain that is not
controlled by other medicines. According to Wolters Kluwer Health, U.S.
sales of Fentora® were approximately $159 million for the twelve months
ending September 2011.
