PDL BioPharma Announces Launch of an Authorized Generic of Tekturna® (aliskiren) in Partnership with Prasco Laboratories

INCLINE VILLAGE, Nev., March 4, 2019 /PRNewswire/ -- PDL BioPharma, Inc. ("PDL", NASDAQ: PDLI) announces the U.S. commercial launch of an authorized generic of Tekturna®, aliskiren hemifumarate 150 mg and 300 mg tablets. The authorized generic has the same drug formulation as Tekturna. The launch is being carried out by Prasco, LLC, d/b/a Prasco Laboratories, under an agreement with PDL's wholly owned subsidiary, Noden Pharma USA, Inc. ("Noden").

Noden will continue to manufacture and commercialize prescription aliskiren products under the Tekturna and Tekturna HCT® (aliskiren and hydrochlorothiazide) brands in the United States, and the Rasilez® and Rasilez HCT® brands in international markets (collectively, the "Tekturna Products"). The authorized generic launch does not include Tekturna HCT.

"We believe being first-to-market with a generic version of aliskiren provides Noden with a distinct competitive advantage, especially given the market and brand recognition for Tekturna that the Noden team established with its promotional activities over the past two years," said Dominique Monnet, President and CEO of PDL. "We are very pleased to partner with Prasco, the recognized leader in the commercialization of authorized generics in the U.S. Together we look forward to continuing to fulfill the needs of U.S. patients who depend on Tekturna for the control of their blood pressure."

In June 2017, Noden Pharma DAC received a Paragraph IV Notice Letter advising that Anchen Pharmaceuticals, Inc. ("Anchen") submitted an Abbreviated New Drug Application ("ANDA") to the U.S. Food and Drug Administration ("FDA") seeking authorization from the FDA to manufacture and market a generic version of Tekturna aliskiren hemifumarate tablets, 150 mg and 300 mg, in the U.S. In June 2018, a settlement agreement was reached by the parties to the litigation granting Anchen a nonexclusive royalty-free license to manufacture and commercialize a generic version of aliskiren in the United States. Anchen's license does not include any right to manufacture or commercialize a generic version of a combination aliskiren-hydrochlorothiazide product. In return, Anchen agreed not to commercialize its generic version of aliskiren prior to March 1, 2019. PDL is not aware of Anchen's plans for, or the timing of a launch of, a generic version of aliskiren or of any other ANDA applications referencing Tekturna.

Total Noden sales of the Tekturna Products in the United States over the trailing 12 months ending September 30, 2018 were $45.1 million, with approximately 79% of sales for Tekturna and 21% for Tekturna HCT. Noden Pharma DAC purchased the Tekturna Products from Novartis in 2016, when the Tekturna Products sales were rapidly declining. Noden engaged a contract sales force which, under the direction of the Noden team, stabilized prescriptions for Tekturna in the United States. Given the possibility for generic entry in 2019 by Anchen, in August 2018 PDL announced plans to commercialize an authorized generic of Tekturna, and Noden terminated its direct sales force in favor of a comprehensive, more cost-efficient program of non-personal promotion in partnership with Archer Healthcare.
