Pharmacodynamic, Pharmacokinetic, and Tolerability Study of a Liquid Form of Lubiprostone in Adult Subjects With Chronic Idiopathic Constipation

2019年11月26日 更新者:Mallinckrodt

A Randomized, Placebo-controlled, Double-blinded, Multicenter Study of the Pharmacodynamics, Pharmacokinetics, and Tolerability of a Liquid Form of Lubiprostone in Adult Subjects With Chronic Idiopathic Constipation

To evaluate the pharmacodynamics and tolerability of a liquid formulation of lubiprostone, as compared to matching placebo, when administered orally to subjects with chronic idiopathic constipation. Additionally, liquid formulation pharmacokinetics, including a comparison of fed and fasted pharmacokinetics, of the liquid formulation will be performed in a subset of subjects.

主要结果指标

结果测量
措施说明
大体时间

within 1 week

次要结果测量

结果测量
措施说明
大体时间
Consistency of SBMs at Week 1
大体时间:at Week 1
Stool consistency was rated according to the 7-point Bristol Stool Form Scale: Type 1 = separate hard lumps, like nuts (hard to pass), Type 2 = sausage-shaped but lumpy, Type 3 = like a sausage but with cracks on the surface, Type 4 = like a sausage or snake, smooth and soft, Type 5 = soft blobs with clear-cut edges (passed easily), Type 6 = fluffy pieces with ragged edges, a mushy stool, Type 7 = watery, no solid pieces; entirely liquid.
at Week 1
Overall Stool Consistency at Week 1
大体时间:at Week 1
Overall stool consistency was rated according to the 7-point Bristol Stool Form Scale: Type 1 = separate hard lumps, like nuts (hard to pass), Type 2 = sausage-shaped but lumpy, Type 3 = like a sausage but with cracks on the surface, Type 4 = like a sausage or snake, smooth and soft, Type 5 = soft blobs with clear-cut edges (passed easily), Type 6 = fluffy pieces with ragged edges, a mushy stool, Type 7 = watery, no solid pieces; entirely liquid.
at Week 1
Mean Change From Baseline in Stool Consistency at Week 1
大体时间:Baseline and Week 1
Stool consistency was rated according to the 7-point Bristol Stool Form Scale: Type 1 = separate hard lumps, like nuts (hard to pass), Type 2 = sausage-shaped but lumpy, Type 3 = like a sausage but with cracks on the surface, Type 4 = like a sausage or snake, smooth and soft, Type 5 = soft blobs with clear-cut edges (passed easily), Type 6 = fluffy pieces with ragged edges, a mushy stool, Type 7 = watery, no solid pieces; entirely liquid. The change from baseline was calculated as post-treatment value (mean) minus the baseline value (mean).
Baseline and Week 1
Overall Straining at Week 1
大体时间:Week 1
Bowel straining was rated on a scale of 0 to 4 (0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe).
Week 1
Mean Change From Baseline in Straining at Week 1
大体时间:Week 1
Bowel straining was rated as 0 = absent, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe. The change from baseline was calculated as post-treatment value minus the baseline value.
Week 1
