July 29, 2015 updated by: AstraZeneca

A Randomized, Open-Label, Multicenter, Comparator-Controlled Study to Examine the Effects of Exenatide Long-Acting Release on Glucose Control (HbA1c) and Safety in Subjects With Type 2 Diabetes Mellitus Managed With Diet Modification and Exercise and/or Oral Antidiabetic Medications

A Randomized, Open-Label, Multicenter, Comparator-Controlled Study to Examine the Effects of Exenatide Long-Acting Release (LAR) on Glucose Control (HbA1c) and Safety in Subjects with Type 2 Diabetes Mellitus Managed with Diet Modification and Exercise and/or Oral Antidiabetic Medications.

Study Overview

Status

Completed

Detailed Description

This trial is designed to examine the effect of exenatide once weekly compared to exenatide twice daily on glucose control and safety in subjects for at least 30 weeks. The study is also designed to examine glucose control during the transition from exenatide twice daily for 30 weeks to exenatide once weekly. Long-term safety and efficacy will be monitored during the open-ended assessment periods. This study will be conducted in approximately 300 subjects with type 2 diabetes treated with diet modification and exercise alone or in combination with a stable regimen of metformin, SU, thiazolidinedione (TZD), a combination of metformin and SU, a combination of metformin and TZD, or a combination of SU and TZD.

Assessment on Event Rate of Treatment-emergent Hypoglycemic Events With SU Use at Screening
Time Frame: Day 1 to Week 364
The major hypoglycemia category included events that, in the judgment of the investigator or physician, resulted in loss of consciousness, seizure, coma, or other change in mental status consistent with neuroglycopenia, in which symptoms resolved after administration of intramuscular glucagon or intravenous glucose, required third-party assistance, and was accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment, whether or not symptoms of hypoglycemia were perceived by the subject. The minor hypoglycemia were accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment and not classified as major hypoglycemia.
Day 1 to Week 364

Time Frame: Day 1 to Week 364
The major hypoglycemia category included events that, in the judgment of the investigator or physician, resulted in loss of consciousness, seizure, coma, or other change in mental status consistent with neuroglycopenia, in which symptoms resolved after administration of intramuscular glucagon or intravenous glucose, required third-party assistance, and was accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment, whether or not symptoms of hypoglycemia were perceived by the subject. The minor hypoglycemia were accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment and not classified as major hypoglycemia.
