Trial Outcomes & Findings for Evaluation of the Efficacy and Safety of ADL5945 for the Treatment of Opioid-induced Constipation in Adults Taking Opioid Therapy for Chronic Noncancer Pain (NCT NCT01207427)

NCT ID: NCT01207427

Last Updated: 2018-09-25

Results Overview

An SBM was defined as a bowel movement (BM) with no laxative use in the previous 24 hours. Each weekly SBM average was calculated as follows: (7 × number of SBMs) / (number of days with nonmissing data). The overall SBM rate for the 4-week double-blind treatment period was calculated as follows: (the average of the first week + the average of the second week + the average of the third week + the average of the fourth week) / 4.

PRIMARY outcome

Timeframe: Baseline, Weeks 1 through 4 of treatment

Population: All participants who were randomized to study treatment and had at least 1 evaluable SBM post-dose measurement during the Double-blind Period. Last-observation-carried-forward (LOCF) was used to impute missing postbaseline values.

An SBM was defined as a bowel movement (BM) with no laxative use in the previous 24 hours. Each weekly SBM average was calculated as follows: (7 × number of SBMs) / (number of days with nonmissing data). The overall SBM rate for the 4-week double-blind treatment period was calculated as follows: (the average of the first week + the average of the second week + the average of the third week + the average of the fourth week) / 4.
