16:17 EDTNKTRNektar announces new data from Phase 2 study of NKTR-102
Nektar Therapeutics announced new data from an investigator-sponsored Phase 2 study of NKTR-102, etirinotecan pegol, in patients with Avastin-refractory high-grade glioma conducted at Stanford Cancer Institute under the direction of Lawrence Recht, M.D., Professor of Neurology and Neurosurgery, with co-investigator Seema Nagpal, M.D., Clinical Assistant Professor of Neurology and Neurological Sciences, Stanford School of Medicine. The primary endpoint was met and exceeded with fifty-five percent of patients in the study achieving six-week progression-free survival. Response and disease progression were assessed by RANO criteria in the trial. Three patients, or 15%, achieved partial responses with NKTR-102 monotherapy with maximum percent reductions in tumor area of 86%, 72%, and 59%. An additional eight patients, or 40%, achieved stable disease as best response. Two of the three patients with RANO responses experienced a long duration of response of 14 and 20 months. Secondary endpoints include median progression-free survival, median survival from time of first NKTR-102 infusion and median overall survival from date of pathologic diagnosis or confirmation of high-grade glioma. NKTR-102 monotherapy was well-tolerated in patients with Avastin-refractory high-grade glioma with low toxicity in spite of being heavily pre-treated and neurologically symptomatic. Only one patient had Grade 3 toxicity attributable to NKTR-102 as a result of not taking anti-diarrheal medication. Hematologic toxicity was mild. As of May 31, there is one patient in the study who is continuing on NKTR-102 monotherapy.

08:33 EDTNKTRNektar receives $40M milestone payment from first commercial sale of Moventig
Nektar (NKTR) announced that it has received a $40M cash payment under a license agreement with AstraZeneca (AZN). The payment was triggered by the first commercial sale of MOVENTIG (naloxegol) in Germany. MOVENTIG is the first once-daily, oral peripherally-acting mu-opioid receptor antagonist (PAMORA) medication approved in the European Union for the treatment of opioid-induced constipation (OIC) in adult patients who have had an inadequate response to laxatives. MOVENTIG is marketed in the U.S. by AstraZeneca as MOVANTIK and is the first once-daily oral PAMORA medication indicated for the treatment of OIC in adult patients with chronic, non-cancer pain. MOVENTIG/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 $40 million milestone payment announced today, Nektar received a $100 million milestone payment upon first commercial sale of MOVANTIK in the U.S. in March of 2015. Nektar is also entitled to 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.
