  Purpose

The purpose of this study is to determine if exenatide will improve global cardiac function in patients with type 2 diabetes mellitus and congestive heart failure, by favorable effects on cardiac metabolism leading to improvement of cardiac efficiency.

Primary Outcome Measures:
  • Cardiac Magnetic Resonance (CMR) will be used to assess global cardiac function (LV ejection fraction). [ Time Frame: week -2 and week 11 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Cardiac oxygen consumption, cardiac efficiency and stress perfusion will be assessed by Positron Emission Tomography (PET) using 11C-acetate and H2-15O [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Cardiac function, dimensions and scarring will be measured bij CMR [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Myocardial diastolic function parameters will be obtained bij trans thoracal echocardiography. Comparisons will be made of strain and torsion measures obtained bij CMR and echocardiography. [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Exercise capacity and performance will be assessed by a 6-minute walking test [ Time Frame: week -1 and week 27 ] [ Designated as safety issue: No ]

Enrollment: 27
Study Start Date: May 2009
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1. Exenatide Drug: exenatide
Exenatide 5 mcg BID for 4 weeks, subsequently increased to 10 mcg BID for the remainder of the study (total of 26 weeks).
Other Name: exenatide-Byetta
Active Comparator: 2. Insulin glargine Drug: Insulin glargine
Insulin glargine will be initiated at 10 IU QD, titrated according to fasting blood glucose concentrations based on general protocol-defined guidance.
Other Name: insulin glargine-Lantus
