SAN FRANCISCO, April 2, 2015 /PRNewswire/ -- Nektar Therapeutics (NASDAQ: NKTR) announced today that it has received a $100 million payment under a license agreement with AstraZeneca. The cash payment under the Nektar-AstraZeneca agreement was triggered by the first commercial sale of MOVANTIK (naloxegol) in the U.S. MOVANTIK is the first once-daily, oral peripherally-acting mu-opioid receptor antagonist (PAMORA) medication for the treatment of opioid-induced constipation (OIC) in adult patients with chronic, non-cancer pain.

"We're pleased that MOVANTIK is now available as an important treatment option for the millions of patients suffering from opioid-induced constipation," said Howard W. Robin, President and Chief Executive Officer of Nektar. "This significant milestone for MOVANTIK showcases Nektar's invention and development of a first-in-class oral medicine that is specifically designed to target the common and potentially debilitating condition experienced by chronic pain patients treated with opioids."

MOVANTIK was developed using Nektar's oral small molecule polymer conjugate technology. MOVANTIK is part of the exclusive worldwide license agreement announced on September 21, 2009 between AstraZeneca and Nektar Therapeutics. Under the terms of the agreement, in addition to the $100 million milestone payment announced today, Nektar is entitled to a $40 million milestone payment upon first commercial sale of MOVANTIK in a major European country, as well as royalties on worldwide net product sales and up to $375 million in sales milestones. The royalty rate in the U.S. starts at 20% and escalates. The royalty rate in Europe and the rest of the world starts at 18% and escalates. Under the agreement, AstraZeneca is responsible for all sales and marketing activities for MOVANTIK worldwide.

About Nektar
Nektar Therapeutics has a robust R&D pipeline in pain, oncology, hemophilia and other therapeutic areas. In the area of pain, Nektar has an exclusive worldwide license agreement with AstraZeneca for MOVANTIK™ (naloxegol), the first FDA-approved once-daily oral peripherally-acting mu-opioid receptor antagonist (PAMORA) medication for the treatment of opioid-induced constipation (OIC), in adult patients with chronic, non-cancer pain. The product is also approved in the European Union as MOVENTIG® and is indicated for adult patients with OIC who have had an inadequate response to laxatives. The AstraZeneca agreement also includes NKTR-119, an earlier stage development program that is a co-formulation of MOVANTIK™ and an opioid. NKTR-181, a wholly-owned mu-opioid analgesic molecule for chronic pain conditions, is in Phase 3 development. NKTR-171, a wholly-owned new sodium channel blocker being developed as an oral therapy for the treatment of peripheral neuropathic pain, is in Phase 1 clinical development. In hemophilia, BAX 855, a longer-acting PEGylated Factor VIII therapeutic is in Phase 3 development conducted by partner Baxter. A BLA for BAX 855 was filed by Baxter to the US FDA in December, 2014 and is currently under review. In anti-infectives, Amikacin Inhale is in Phase 3 studies conducted by Bayer Healthcare as an adjunctive treatment for intubated and mechanically ventilated patients with Gram-negative pneumonia.

Examples of forward-looking statements include, among others, statements we make regarding the potential of MOVANTIK (naloxegol) and the value and potential of our polymer conjugate technology and research and development pipeline. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results to differ materially from those indicated in the forward-looking statements include, among others, (i) the commercial potential of a new drug at the early stages of commercial launch, such as MOVANTIK, is difficult to predict and will have a significant impact on our future results of operation and financial condition; (ii) scientific discovery of new medical breakthroughs is an inherently uncertain process and the future success of the application of our technology platform to potential new drug candidates is therefore highly uncertain and unpredictable and one or more research and development programs could fail; (iii) patents may not issue from our patent applications for our drugs (including MOVANTIK) and drug candidates, patents that have issued may not be enforceable, or additional intellectual property licenses from third parties may be required; and (iv) the outcome of any existing or future intellectual property or other litigation related to our drugs and drug candidates and those of our collaboration partners including MOVANTIK.
