Trial record 1 of 1 for:
Assessment of Whole Gut Transit Time Using the SmartPill Capsule (WholeGut)
This study has been completed.

The SmartPill Corporation
First received: January 8, 2008
Last updated: August 28, 2008
Last verified: August 2008
Our null hypothesis states that the two techniques (Sitzmarks radioopaque markers and SmartPill) are equivalent and is demonstrated if the study population shows a correlation of 0.7 or higher.
||Observational Model: Case Control
Time Perspective: Prospective
||Assessment of Whole Gut Transit Time Using the SmartPill Capsule: a Multi-Center Study
Primary Outcome Measures:
- whole gut transit time [ Time Frame: 2 days and 5 days ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Determine regional gut (gastric, small bowel, colonic) transit times [ Time Frame: continuous time measure until caspule elimination ] [ Designated as safety issue: No ]

| Primary Completion Date:
||June 2008 (Final data collection date for primary outcome measure)
healthy adult subjects with no history or current gastrointestinal disorders or conditions
Adult subjects with functional constipation as define by Rome II criteria
The purpose of the study is to measure total gastrointestinal transit time using SmartPill GI Monitoring System with pH.p Capsule and compare the transit time determined by capsule transit to the conventional radioopaque marker technique.
Both techniques are simultaneously applied in normal and constipated adult populations.
|Ages Eligible for Study:
||18 Years to 80 Years
