Handa Pharmaceuticals, LLC (“Handa”), a specialty pharmaceutical company based in Fremont, California, today announced that it has reached an agreement with AstraZeneca to settle its U.S. patent litigation regarding Handa’s Abbreviated New Drug Application (“ANDA”) for Quetiapine Fumarate Extended-Release Tablets 50 mg., 150 mg., 200 mg., 300 mg., and 400 mg., a generic version of AstraZeneca’s SEROQUEL XR®. Handa is the first applicant to file an ANDA for SEROQUEL XR® 50 mg., 150 mg., 200 mg., and 300 mg. containing a Paragraph IV certification, under the provisions of the Hatch-Waxman Act.

Under the terms of the settlement agreement, AstraZeneca has granted Handa a license to enter the U.S. market with a generic version of SEROQUEL XR® on November 1, 2016 or earlier upon certain circumstances. Handa and AstraZeneca have filed a proposed Consent Judgment with the U.S. District Court for the District of New Jersey requesting that the Court dismiss the pending legal action between Handa and AstraZeneca.

“We are pleased to resolve Handa’s patent litigation with AstraZeneca on our First-to-File ANDA for Quetiapine XR. This settlement agreement allows Handa to bring a generic version of SEROQUEL XR® to the U.S. market prior to the November 2017 expiration of AstraZeneca’s formulation patent, without incurring the uncertainty and risk inherent with patent litigation,” said Bill Liu, Handa’s President and CEO.

According to IMS Health, annual sales of SEROQUEL XR® in the U.S. were about $883 million for the twelve months ended March 31, 2011.
