  Purpose

The purpose of this study is to investigate the effect of combined glucagon-like-peptide-1 (GLP-1) analogue and metformin therapy on glucose metabolic and cardiovascular endpoints compared to metformin monotherapy in patients with coronary artery disease (CAD) and newly diagnosed type 2 diabetes (T2D).

It is hypothesized that GLP-1 analogue added to backbone therapy of metformin in CAD patients with T2D will improve beta-cell function, left ventricular ejection fraction (LVEF), heart rate variability and lower 24h blood pressure among other selected endpoints.

The present study on CAD patients with newly diagnosed T2D will address these selected endpoints during an investigator initiated, randomized, double blind, crossover, placebo-controlled 12 + 12 weeks intervention study with a 2 week wash-out period.

Arms Assigned Interventions
Placebo Comparator: Placebo + metformin Drug: Placebo
Volume-matched placebo injection pen is administered by the participant once daily by subcutaneous injection. It is given independent of meals. The starting dose is 0.6 mg volume-matched placebo. After 2 weeks the dose will be increased to 1.2 mg. The dose will be further increased after 4 weeks to 1.8 mg. After a total of 12 weeks of treatment, a wash-out period of 2 weeks follows. Subsequently, the participant will be crossed over to a second period of 12 weeks of treatment with liraglutide.
