Assessment method [1]

Adverse event (AE) was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Serious adverse events (SAEs) included death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent 1 of the outcomes listed in this definition. TEAEs were defined as an AE that emerged during the treatment period. Any TEAEs included both treatment-emergent SAEs and non-serious AEs. A summary of serious and all other non-serious AEs regardless of causality is located in the Reported Adverse Events module.

Change From Baseline in Weekly Bowel Movement (BM) Rate Through Follow-up
Query!
Assessment method [1]
0
0
Weekly BM rate was derived as the total number of BMs reported in a month divided by the total number of days with non-missing BM diary information in the same month, then multiplied by 7 to normalize to a weekly rate. If the total number of days with non-missing BM diary information in a given month was less than 10 days, the weekly BM rate for the month was defined as missing. The weekly BM rate at baseline was calculated based on the screening period (Days -14 to -1). If the total number of days with non-missing BM diary information during the screening period was less than 5 days, the weekly BM rate at baseline was defined as missing.

Summary
Brief summary
This study is designed to evaluate the long-term safety and tolerability of the subcutaneous (SC) injection form of N-methylnaltrexone bromide (MOA-728) for the treatment of opioid-induced constipation in participants with nonmalignant pain. The study consists of a 2-week screening period, a 48-week open-label treatment period and a 2 week follow-up period. Participants will need to agree to self-administer SC injections, complete daily diaries, and check-in via a daily telephone call during the study.
