Detailed description

This study in patients with IBS-C is a randomized, double-blind, placebo-controlled, parallel-group clinical trial with 12 weeks of study drug therapy. Screening/Baseline: Patients will undergo an up to 28-day Screening/Baseline period to allow for any necessary diagnostic procedures, allow for required washout of medications and to determine study eligibility. If otherwise eligible based on screening criteria, patients will undergo a 2-week baseline assessment using an electronic diary where they will record daily assessments of bowel movements (BMs), stool consistency (Bristol Stool Form Scale-BSFS), abdominal pain and other IBS-related symptoms. Data from the two-week electronic diary assessment just prior to the randomization visit will be used to confirm IBS-C and study eligibility as well as define the patient's baseline from which change will be determined. Treatment: Patients who meet all entry criteria will be randomized (1:1:1) to one of three blinded treatment groups on Day 1 of the Treatment period. Patients will take an oral dose of study drug OD for 12 weeks and continue the daily electronic diaries (BMs, rescue medication use, abdominal pain, and other symptoms). During treatment weeks 4, 8, and 12, patients will return to the clinic to undergo safety and efficacy assessments. Post-Treatment: For 2 weeks after completing dosing, patients will continue to complete daily electronic diaries. Patients will then return to the clinical site for a final follow-up visit during Week 14 following randomization. The planned duration of participation in this study will be at least 116 days from signing of informed consent through post-treatment or up to approximately 135 days with visit windows considered.
