Primary Outcome Measures
NameTimeMethod
Change From Baseline in Mean Weekly Spontaneous Bowel Movement (SBM) Frequency in Subjects Without Dose Reduction Prior to Week 8Baseline and Week 8
Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Mean Weekly SBM FrequencyBaseline, Week 12, and Weeks 1-12

For overall assessment of change, average weekly rating was calculated from data collected from Week 1 through Week 12.

First Post-dose SBM24 and 48 hours post-dose

The number of participants that experienced first post-dose SBM 24 and 48 hour of dose initiation.

Responder RateUp to 12 weeks

Number of participants, who remained on treatment for at least 8 weeks, and reported response (\>=3 SBMs) for at least 50% of weeks on study.

Mean Changes From Baseline in Straining, Stool Consistency, Constipation Severity, Abdominal Bloating, Abdominal Discomfort, and Bowel Habit RegularityWeeks 1-12

Ratings over 12-week treatment period were averaged and difference from baseline score calculated Straining scale: 0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe Stool consistency scale: 0 = very loose, 1 = loose, 2 = normal, 3 = hard, 4 = very hard (little balls) Constipation severity scale: 0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe Abdominal bloating scale: 0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe Abdominal discomfort scale: 0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe Bowel habit regularity scale: 7-point scale, where 1 = very regular and 7 = very irregular

Treatment EffectivenessWeeks 1-12

Treatment effectiveness scale: 0 = not at all effective, 1 = a little bit effective, 2 = moderately effective, 3 = quite a bit effective, 4 = extremely effective
