|Official Title:||A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase IIb Study to Evaluate the Efficacy and Safety of Multiple Alvimopan Dosage Regimens for the Treatment of Opioid-Induced Bowel Dysfunction in Cancer Pain Subjects|

Experimental: Alvimopan 0.5 mg Twice Daily (BID)
0.5 milligrams (mg) of alvimopan was administered orally BID for 3 weeks.
Experimental: Alvimopan 1 mg Once Daily (QD)
0.5 mg of alvimopan was administered orally QD for 3 days, then 1 mg of alvimopan QD for the remaining 3 weeks. Placebo was administered orally QD to maintain the blind.
A protocol amendment dropped this arm because another study had demonstrated 1 mg QD treatment to have similar efficacy but a less favorable gastrointestinal-related safety profile compared with 0.5 mg BID treatment.
|Drug: alvimopan Drug: placebo|
Experimental: Alvimopan 1 mg Twice Daily (BID)
0.5 mg of alvimopan was administered orally BID for 3 days, then 1 mg of alvimopan BID for the remaining 3 weeks.

- Additional measures of Bowel movement (BM) frequency and symptoms, safety profile of the treatment regimens and any changes in pain intensity or opioid use.
