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.

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.

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).
