An Exploratory Study on the Effects of Repeat Doses of Albiglutide Compared to Exenatide on Gastric Myoelectrical Activity and Gastric Emptying in Type 2 Diabetes Mellitus Subjects

• Status: Terminated
• Trial end date: 2017-03-16

Summary

The primary objective of this study is to compare the effect of albiglutide and exenatide on gastric myoelectrical activity (GMA), gastric emptying (GE) and nausea (as measured by visual analogue scale [VAS]) in subjects with type 2 diabetes mellitus (T2DM). The study is divided in two parts. Part A will characterize the GMA, GE and nausea response to exenatide and confirm exenatide as a positive control for Part B. Part B will compare the effects of albiglutide and exenatide on GMA, GE and nausea.

Part A is a single arm, open-label design and all subjects will receive 10 microgram (mcg) subcutaneous exenatide twice daily for 5 days. This part will comprise 3 study periods: a 3-week screening/wash-out, 5-day treatment, and follow-up (within 7 days after the last dose of exenatide). The total duration of a subject's participation in Part A will be approximately 5 weeks. Once Part A is complete, data will be reviewed and a decision to progress to Part B will be made.

In Part B, subjects will be randomized 1:1 to receive either albiglutide (starting dose of 30 milligrams [mg] once weekly for 4 weeks, followed by 50 mg once weekly for 4 weeks) or exenatide (starting dose of 5 mcg twice daily for 4 weeks, followed by 10 mcg twice daily for 4 weeks). The total duration of a subject's participation in the study will be approximately 15 weeks.
