Purpose
This study is a multi-center, open-label comparison study and aimed to evaluate the preliminary performance of this 13C-uracil GEBT to examine its abilities of identifying abnormal (accelerated or delayed) gastric emptying rates in subjects.

Primary Outcome Measures:
- Expired 13CO2 concentrations [ Time Frame: 6 hours ] [ Designated as safety issue: No ]Expired 13CO2 concentrations are obtained from breath test. The values will be calculated to Re(t)[B] semi-solid: remaining (%) of semi-solid test meal in stomach at t, t1/2[B] semi solid: half emptying time of semi-solid test meal , and tlag[B] semi-solid: lag time of semi-solid test meal.
Secondary Outcome Measures:
- Concentrations of 13C-uracil and its major metabolites in plasma and urine [ Time Frame: 6 hours ] [ Designated as safety issue: No ]PK parameters of 13C-uracil and its major metabolites, DHU and UPA, including AUCt, AUC∞, Cmax, tmax, λz, and t1/2,z, will be calculated based on plasma and urine concentration for 13C-uracil and its metabolites, and expired 13CO2-excretion, which calculated based on expired 13CO2 concentrations

Experimental: 13C-uracil and 99mTc sulfur colloid
Subjects will consume the Semi-solid Test Meal containing 500 uCi 99mTc sulfur colloid and 100 mg of 13C-uracil.

Drug: 13C-uracil and 99mTc sulfur colloid
Visit 2: Day 15+-4, perform the Breath Test and Scintigraphy with Semi solid Test Meal containing 100 mg of 13C-uracil and 500 uCi
Other Name: C13-URA and Technetium Tc 99m Sulfur Colloid Injection
|
Detailed Description:
Approximately equal numbers of subjects will be enrolled in each of the 3 groups (with normal gastric emptying, with rapid (accelerated) gastric emptying, and with delayed gastric emptying (gastroparesis)) to complete at least 10 subjects per group.
The subjects will first have their gastric emptying rates investigated by scintigraphy using the Solid Test Meal containing 500 uCi 99mTc sulfur colloid at Visit 1. Second, the subjects will have their gastric emptying rates investigated by scintigraphy and 13C-uracil GEBT simultaneously using the Semi solid Test Meal containing 500 uCi 99mTc sulfur colloid and 100 mg of 13C-uracil, respectively, at Visit 2. A comparison will be made between the results obtained at Visits 1 and 2 along with a comparison of the data obtained during Visit 2 for evaluation of the 13C-uracil GEBT.
