Effect of Exenatide Plus Metformin vs. Insulin Aspart Plus Metformin on Glycemic Control and Hypoglycemia in Patients With Type 2 Diabetes

Phase 3

Completed

• Conditions: Type 2 Diabetes Mellitus
• Interventions: Drug: exenatide twice daily (BID); Drug: premixed insulin aspart twice daily (BID)

• Registration Number: NCT00434954
• Lead Sponsor: AstraZeneca

Brief Summary

This study in Germany is designed to compare the effects of twice-daily exenatide plus metformin and twice-daily premixed human insulin aspart plus metformin with respect to glycemic control, as measured by HbA1c, combined with the percentage of patients with at least one treatment-emergent hypoglycemic episode. Patients will be treated with study therapy for approximately 26 weeks.

Arm && Interventions

Group	Intervention	Description
Exenatide Twice Daily (BID)	exenatide twice daily (BID)	-
Premixed Insulin Aspart Twice Daily (BID)	premixed insulin aspart twice daily (BID)	-

Primary Outcome Measures

Name	Time	Method
Change in Glycosylated Hemoglobin (HbA1c)	Baseline and 26 weeks	Change in HbA1c from baseline after 26 weeks of treatment (i.e., HbA1c at week 26 minus HbA1c at week 0)
Incidence of Hypoglycemia (Percentage of Participants With at Least One Hypoglycemic Episode)	26 weeks	Risk for first hypoglycemic episode (blood glucose \<=3.9 mmol/L or severe episode) to occur up to week 26

Secondary Outcome Measures

Name	Time	Method
Percentage of Subjects Achieving HbA1c Target of < 6.5%	26 weeks	Percentage of subjects achieving HbA1c target of \< 6.5% at the end of study (week 26) \[i.e., number of subjects who achieved HbA1c \< 6.5% divided by total number of subjects times 100%\].
7 Point Self-monitored Blood Glucose (SMBG) Profiles	Baseline and 26 weeks	7-point self-monitored blood glucose profiles at baseline and the end of the study, measured at 7 times during the day (pre-breakfast, 2 hours post-breakfast, pre-lunch, 2 hours post-lunch, pre-dinner, 2 hours post-dinner, and 3:00am).
Incidence of Hypoglycemic Episodes [Blood Glucose <= 3.0 mmol/L or Severe] (Percentage of Subjects Who Experienced at Least One Treatment-emergent Hypoglycemic Episode During the 26-week Treatment Period)	26 weeks	Risk for the first hypoglycemic episode to occur up to Week 26 (percentage of subjects who experienced at least one treatment-emergent hypoglycemic episode during the 26-week treatment period)\[ i.e., number of subjects experiencing at least one hypoglycemic episode divided by total number of subjects times 100%\]
Patient Reported Outcomes: Diabetes Treatment Satisfaction Questionnaire (DTSQ)	Baseline and 26 weeks	Total DTSQ treatment satisfaction score at baseline (week 0) and after 26 weeks of treatment (LOCF). Total DTSQ treatment satisfaction score is derived as sum score of the individual components 1 and 4-8 of the DTSQ questionnaire. Each component is scored on a scale of 0 (worst case) to 6 (best case). Higher values represent higher treatment satisfaction.
Percentage of Subjects Achieving HbA1c Target of < 7.0%	26 weeks	Percentage of subjects achieving HbA1c target of \< 7.0% at the end of study (week 26) \[i.e., number of subjects who achieved HbA1c \< 7.0% divided by total number of subjects times 100%\].
Change in Body Weight	Baseline and 26 weeks	Change in body weight from baseline after 26 weeks of treatment (i.e., body weight at week 26 minus body weight at week 0)
Patient Reported Outcomes: Quality of Life (SF-12)	Baseline and 26 weeks	SF-12 Physical and Mental Component Summary Scores at baseline (week 0) and after 26 weeks of treatment (LOCF). SF-12 Physical and Mental Component Summary Scores are normalized scores ranging from 0 (worst case) to 100 (best case), and are derived from responses to 12 questions. Scores \> 50 indicate an above-average health status.
Change in Body Mass Index (BMI)	Baseline and 26 weeks	Change in BMI from baseline after 26 weeks of treatment (i.e., BMI at week 26 minus BMI at week 0)
Incidence of Nocturnal Hypoglycemia (Percentage of Subjects Who Experienced at Least One Episode of Nocturnal Hypoglycemia During the 26 Week Treatment Period)	26 weeks	Risk for first nocturnal (night-time) hypoglycemic episode to occur up to week 26 (percentage of subjects who experienced at least one episode of nocturnal hypoglycemia during the 26 week treatment period) \[i.e., number of subjects who experienced nocturnal hypoglycemia divided by total number of subjects times 100%\].
Blood Lipid Levels	Baseline and 26 weeks	Total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol (calculated), and triglyceride levels at baseline (week 0) and the end of the study (week 26)
