Increases to the opioid regimen are permitted. 6.Has a diagnosis of constipation, defined as either a.Fewer than 3 bowel movements during the previous week by history, and no clinically notable laxation in the 24 hours before the first dose of test article, or b.No clinically notable laxation in the 48 hours before the first dose of test article.

This means that there must be a standing laxative order (not PRN). a.A subject who meets inclusion criterion 6a and uses or used a rescue laxative (or enema/suppository) that produces a notable bowel movement within the 24 hours before the first dose of test article must wait to be laxation free for 24 hours in order to receive test article. b.A subject who meets inclusion criterion 6b and receives or received a rescue laxative (or enema/suppository) that produces a notable bowel movement within the 24 hours before the first dose of test article must wait to be laxation free for 48 hours in order to receive test article.

| Main Objective: Primary: The primary objective of this study is to evaluate the efficacy and safety of a fixed dose of SC methylnaltrexone in inducing laxation over a 7-day period in subjects with advanced illness and OIC. ;Secondary Objective: Secondary: The secondary objectives of this study are to assess the effect of SC methylnaltrexone on patient-reported constipation symptoms and constipation-related quality of life and to assess the efficacy of SC methylnaltrexone beyond 7 days in individuals with advanced illness and OIC.;Primary end point(s): Proportion of subjects who have a laxation response within 4 hours after at least 2 of the first 4 doses (the first week of treatment). | — |
