简要总结
This is a randomized, double blind, placebo controlled trial to evaluate the tolerability of MHS 1031. Tolerability will be assessed using the change in complete spontaneous bowel movements (CSBM), PRO questionnaires, concomitant medication assessments, and assessment of adverse events, from baseline (determined during Screening Phase) to Week 8 (Day 56). The primary analysis will be conducted to assess the tolerability of MHS 1031 product and of the formulated placebo in randomized subjects with CIC diagnosed according to a modified Rome IV criteria.
详细描述
This study will be conducted as a multicenter, randomized, double blind, placebo controlled trial to evaluate the tolerability of MHS 1031 and tolerability of the formulated placebo. The study consists of a screening phase to establish eligibility and baseline values, followed by 3 distinct study periods.
Subjects with CIC will be determined eligible for the study based on modified Rome IV criteria during a 2 week Screening Phase. Approximately 200 subjects with CIC who meet all eligibility criteria will be randomized in a 1:1 ratio, with equal numbers of each in each successive group of 50 subjects, to receive either MHS 1031 [1 g (1.4 ml) per day] or 1.4 ml of placebo (1:1) for 8 weeks (Product/Placebo Phase). Upon completion of the 8 week Product/Placebo Phase, Subjects will enter a 4 week open label Product Phase, during which all subjects will receive MHS 1031. Subjects who complete the study will enter a 2-week Follow-up Phase, during which subjects will take neither placebo nor MHS 1031.
During the study, tolerability will be assessed on the basis of Patient Reported Outcomes (PRO questionnaires), concomitant medication assessments, and assessment of adverse events. Tolerability is defined as no overall worsening of constipation measurement scores after 8 weeks of taking the product or the placebo compared to baseline scores.

结局指标
主要结局
Tolerability as assessed using a PRO questionnaire, a 4 question Daily BM Questionnaire
时间窗: 8 weeks
A Complete Spontaneous Bowel Movement (CSBM) is a Bowel Movement (BM) that occurs in the absence of laxative use within 24 hours of the BM and the patient reports a feeling of complete evacuation. Tolerability is defined as no overall worsening of constipation measurement scores after 8 weeks of taking the product or the placebo compared to baseline scores. More complete spontaneous bowel movements is better, fewer is worse.
