GSK return rights to Entereg to Adolor

14 September 2008

UK drug major GlaxoSmithKline has returned the worldwide rights for Entereg (alvimopan) in the treatment of chronic opioid bowel dysfunction to originator, US drugmaker Adolor.

GSK also returned the rights related for the use of the drug in irritable bowel syndrome and non-opioid induced forms of constipation or bowel dysfunction, but there have been no active development programs for these indications. The drug major is, however, retaining rights for postoperative ileus and the companies will continue to collaborate on the US development and commercialization of Entereg for that indication.
