Long-Term Safety Evaluation Of Treatment Of Constipation Due To Opioids Being Taken For Persistent Non-Cancer Pain - Full Text View

Purpose

Adults who are taking opioid therapy for persistent non-cancer pain and have resulting opioid-induced bowel dysfunction (OBD) will be randomized (1:1) to alvimopan or placebo. The primary objective of this phase 3 long-term safety study is to compare alvimopan with placebo for safety and tolerability in the treatment of OBD. The primary safety endpoint is based on the frequency of reported adverse events. Subjects will be required to attend 8 clinic visits over approximately 1 year.
