Study Endpoints

Primary Endpoints

Change From Baseline (CFB) in 4-week Overall Spontaneous Bowel Movement (SBM) Frequency Rate During the Treatment Period
Baseline (14-day prior to randomization and up to randomization) to Week 4

SBM was defined as a BM that occurred in the absence of laxative, suppository, or enema use on the calendar day of the BM or the calendar day before the BM. SBM rate was defined as SBMs/week during the 4-week Treatment period. Participants recorded the occurrence of BMs and use of rescue medication, morning and evening, daily in an eDiary since pretreatment period. The SBM frequency rate (SBMs/week) during the analysis period for each participant were calculated as \[(total number of SBMs in the analysis period/number of days in the analysis period)\*7\]. Baseline value was based on values collected 14 days before randomization up to randomization. Change from Baseline was calculated as the SBM frequency rate during the 4-week treatment period - SBM frequency rate at baseline. A positive change from Baseline indicates improvement. Least squares mean (LSM) and standard error (SE) were calculated using analysis of covariance (ANCOVA) method.
