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

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. Participants will be required to attend 8 clinic visits over approximately 1 year.
