Collaborator:
Eli Lilly and Company
Information provided by (Responsible Party):
AstraZeneca
  Purpose
As exenatide slows the rate at which materials leave the stomach, it is likely to alter the rate of intestinal absorption of oral drugs when administered within a certain timeframe relative to exenatide. In addition, the residence time within the stomach of other medication may be prolonged and data from this study will help assess the change in residence time in the presence of therapeutic doses of exenatide. This study will also evaluate the relationship between blood levels of exenatide and parameters measuring rate of stomach emptying.

Primary Outcome Measures:
  • To detect the mean difference in half gastric emptying time for a solid meal between any treatment and placebo [ Time Frame: up to 12 hours post meal consumption ]
    A dose of exenatide or placebo is given before the morning meal. After eating the test meal, images will be recorded at approximately 5 minute intervals from ingestion of the test meal until 3 hours after the meal, then every 10 minutes until 6 hours after the meal. In cases where significant radioactivity is observed at 6 hours after the meal, additional scintigraphic images may be taken periodically at the discretion of the investigator, until counts approach low values for up to 12 hours after the meal.

Arms Assigned Interventions
Experimental: Sequence 1
Exenatide 5 mcg - Exentatide 10 mcg - Placebo
Drug: exenatide and placebo
Period 1 = Subcutaneous injections of exenatide 5mcg twice daily for 4 days and once in the morning of the 5th day. Period 2 = Subcutaneous injections of exenatide 5mcg twice daily for 2 days, followed by 2 days of twice daily 10 mcg doses, 10mcg once in the morning of the 5th day.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects with at least 1 year history of type 2 diabetes mellitus.
  • Subjects controlled by oral antidiabetic agents or diet and exercise demonstrated by a screening HbA1c ≥7.0% and ≤10.0%.
  • Between the body mass index (BMI) of 19 kg/m2 and 40 kg/m2, inclusive.

Exclusion Criteria:
