Measure Description |
Time Frame |
|---|---|---|
|
Number of Subjects With Treatment-emergent Adverse Events
Time Frame: 6 Weeks (from Day -1 to the follow-up visit on Day 42)
|
Treatment-emergent adverse event is defined as any adverse event (untoward medical experience occurring to a subject whether or not it is related to the study drug) with an onset date/time at/after the placebo dosing on Day -1.
|
6 Weeks (from Day -1 to the follow-up visit on Day 42)
|
|
Number of Stools and Type of Stools Based on Bristol Stool Chart
Time Frame: 7 Weeks (from Day -6 to the follow-up visit on Day 42)
|
Number of occurrences for each stool type was reported based on their type assessed from Bristol Stool Chart.
The Bristol Stool Chart was used to assess the stool shape using a 7-point scale.
Where, 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.
A score of 1 or 2 indicates constipation while a score of 6 or 7 indicates diarrhea.

7 Weeks (from Day -6 to the follow-up visit on Day 42)
|
|
Trough Concentrations of JTT-662 in Plasma on Days 1, 7, 10, 14, 15, 21 and 28
Time Frame: 28 Days
|
Trough plasma concentration is the measured concentration at the end of a dosing interval at steady state (taken directly before next administration).
Blood samples were collected at specific timepoints to measure trough plasma concentrations of JTT-662 in the subjects randomized to JTT-662 treatment groups.
|
28 Days
|
|
Change From Baseline in AUEC0-4 for Plasma Postprandial Glucose (PPG) Compared to Placebo on Days 1, 14 and 28
Time Frame: Days 1, 14 and 28
|
Change from baseline in the AUEC0-4 (area under the observed effect-time curve from the start of breakfast until the 4 hour time point) for PPG were calculated using the corresponding Day -1 value as baseline and compared to the placebo values.
Negative values represent greater reduction in PPG from baseline values compared to placebo.
