MOVENTIG (naloxegol) receives EC approval for treatment of opioid-induced constipation

Nektar Therapeutics (NASDAQ: NKTR) reported partner AstraZeneca today announced that MOVENTIG® (naloxegol) has been granted Marketing Authorisation by the European Commission (EC) for the treatment of opioid-induced constipation (OIC) in adult patients who have had an inadequate response to laxative(s). MOVENTIG is the first once-daily oral peripherally-acting mu-opioid receptor antagonist (PAMORA) to be approved in the European Union (EU).

Opioids play an important role in chronic pain relief and work by binding to mu-receptors in the central nervous system, but they also bind to mu-receptors in the gastrointestinal tract, which can result in patients suffering from OIC.

Briggs Morrison, Executive Vice President, Global Medicines Development & Chief Medical Officer, AstraZeneca, said: "Constipation is one of the most common side effects for those using opioid pain medication. We're very pleased to have received marketing authorisation for MOVENTIG, as it allows us to offer a new treatment option for the millions of patients across Europe who suffer from opioid-induced constipation and haven't responded to laxatives."

The approval of MOVENTIG was based on data from the KODIAC clinical programme, which was comprised of four studies: KODIAC-4, -5, -7 and -8. KODIAC-4 and -5 were both placebo controlled, double-blind, 12 week studies assessing safety and efficacy, while KODIAC-7 was a 12 week safety extension to KODIAC-4, and KODIAC-8 was a 52 week open label, long-term safety study.

The EC marketing authorisation applies to all member states of the EU, Iceland, Norway and Lichtenstein. Today's announcement follows the approval on 16 September 2014 of MOVANTIKTM (naloxegol) tablets by the US Food and Drug Administration, as the first once-daily PAMORA for the treatment of OIC in adult patients with chronic non-cancer pain.
