AstraZeneca has entered into a licensing agreement with Grünenthal GmbH for the exclusive rights to Zurampic (lesinurad) in Europe and Latin America.

Zurampic was approved by the European Medicines Agency (EMA) in February 2016, in combination with a xanthine oxidase inhibitor (XOI), for the adjunctive treatment of hyperuricemia (excess of uric acid in the blood) in adult patients with uncontrolled gout.

Grünenthal will acquire the exclusive rights to Zurampic in all 28 European Union member states, Switzerland, Iceland, Norway and Lichtenstein, and in all Latin-American countries including Mexico, the Dominican Republic and Cuba. In addition, Grünenthal will also obtain the exclusive rights to the fixed-dose combination of lesinurad and allopurinol in these markets. This combination is currently in clinical trials.

Under the terms or the agreement, Grünenthal will submit the fixed-dose combination programme for regulatory review and will pay AstraZeneca up to $230 million in sales and other related milestones over the lifetime of the contract. Grünenthal will also pay tiered, low double-digit royalties on annual Product Sales. AstraZeneca will initially manufacture and supply Zurampic to Grünenthal and will undertake the European post-approval commitment on Grünenthal’s behalf. From 1 October 2021, Grünenthal has the option to take over manufacturing of Zurampic.

Luke Miels, executive vice president, global product and portfolio strategy, AstraZeneca, said: “Grünenthal has an established presence across European and Latin American markets and extensive expertise in inflammatory diseases. This agreement allows us to further focus our resources on our strategic priorities.”

Prof. Dr. Eric-Paul Pâques, CEO, Grünenthal, said: “We are highly committed to the research, development and commercialisation of innovative therapies that bring true benefits to patients. Zurampic is a strong addition to our existing portfolio of innovative therapies in the areas of inflammatory diseases and chronic pain. We will thus use our capabilities to provide patients in our markets with this innovative new medicine to better control their condition.”

Gout is a serious, chronic, progressive and potentially debilitating form of inflammatory arthritis that affects more than 7.8 million people in the major European and Latin American market.

Revenue from the licensing agreement will provide AstraZeneca with future recurring Externalisation Revenue from expected milestone payments and tiered, low double-digit percent royalty payments on Product Sales. The agreement does not impact AstraZeneca¹s financial guidance for 2016.

Zurampic (lesinurad) is the first in a new class of medicines called Selective Uric Acid Reabsorption Inhibitors (SURI) that work selectively to complement xanthine oxidase inhibitors (XOIs) in the treatment of hyperuricemia associated with uncontrolled gout. Zurampic is not recommended for the treatment of asymptomatic hyperuricemia and should not be used as monotherapy. XOIs reduce the production of uric acid; Zurampic increases the excretion of uric acid. Together, the combination of Zurampic and an XOI provides a dual mechanism of action that both decreases production and increases excretion of uric acid, thereby lowering serum uric acid (sUA) levels in patients who have not achieved target serum acid levels with XOI treatment alone. Zurampic selectively inhibits the function of transporter proteins urate transporter (URAT1) and organic anion transporter 4 (OAT4), involved in uric acid reabsorption in the kidney. In people, Zurampic does not inhibit OAT1 and OAT3, which are drug transporters in the kidney associated with drug-drug interactions. The efficacy of Zurampic was established in three Phase III clinical trials that evaluated a once daily dose of Zurampic in combination with the XOI allopurinol or febuxostat compared to XOI alone.

In April 2016, AstraZeneca entered into a licensing agreement with Ironwood Pharmaceuticals for the exclusive US rights to Zurampic and the fixed-dose combination of lesinurad and allopurinol.

The Grünenthal Group is an independent, family-owned, international research-based pharmaceutical company headquartered in Aachen, Germany.
