Handa Pharmaceuticals, LLC (“Handa”), a specialty pharmaceutical company based in Fremont, California, today announced that it has entered into an exclusive acquisition and license agreement with Par Pharmaceutical, Inc. (NYSE: PRX) for Handa’s Abbreviated New Drug Application (“ANDA”) for Dexlansoprazole Delayed Release Capsules, a generic version of Takeda’s DEXILANT®. Handa believes that it is the first applicant to file an ANDA for the 60 mg strength of DEXILANT® containing a Paragraph IV certification under the provisions of the Hatch-Waxman Act, which would potentially provide 180 days of marketing exclusivity.

Under the terms of the agreement, Handa has received a payment from Par for the ANDA, giving Par the exclusive rights to market, sell and distribute Dexlansoprazole Delayed Release Capsules in the U.S. under the ANDA, subject to final FDA approval. Handa will receive a percentage of profits from the sales of the product.

Handa is currently involved in patent litigation concerning the ANDA in the U.S. District Court for the District of Northern California. Par will assume control of ongoing litigation.

According to IMS Health data, annual sales of DEXILANT® Delayed Release Capsules, 60 mg, in the U.S. are approximately $517 million.
