Arm | Intervention/treatment |
---|---|
Experimental: Liraglutide+standard-of-care treatment
Intervention: Liraglutide is added to existing standard-of-care treatment containing one or more oral anti-hyperglycemic agents or insulin or a combination of these agents with the exception of other incretin and SGLT2i therapies.
|
Drug: Liraglutide+standard-of-care treatment
Liraglutide is available if pre-filled pens (6 mg/ml) as a solution for injection (Victoza®). One ml of solution contains 6 mg of Liraglutide (human glucagon-like peptide-1 analogue produced by recombinant DNA technology in Saccharomyces cerevisiae). One pre-filled pen contains 18 mg Liraglutide in 3 ml. Liraglutide is added to existing standard-of-care treatment containing one or more oral anti-hyperglycemic agents or insulin or a combination of these agents with the exception of other incretin and SGLT2i therapies in accordance with local clinical practice guidelines. Other Name: Victoza |
Active Comparator: standard-of-care treatment
standard-of-care treatment with the exception of incretin and SGLT2i therapies. This approach expect to yield similar glycemic control in the two study groups.
|
Other: standard-of-care treatment
Standard-of-care treatment including: metformin should be given as the first line therapy as long as it is tolerated and not contraindicated; other agents, including sulfonylureas or glucosidase inhibitor or insulin, should be added to metformin .Glycemic control will be managed by the investigators in accordance with local clinical practice guidelines by the adjustment of concomitant glucose-lowering agents or the addition of new antidiabetic medications with the exception of incretin and SGLT2i therapies. This approach expect to yield similar glycemic control in the two study groups. |
- Initial and absolute claudication distance [ Time Frame: 24 weeks ]The primary outcome measures used to assess efficacy were pain-free walking distance (distance walked to the onset of symptoms, or the initial claudication distance [ICD]) and the maximum distance walked (absolute claudication distance [ACD]) on standardized treadmill testing. Evaluation of walking performance was accomplished with standardized treadmill testing. A constant speed of 3.2 km/h (2mile/h) and a fixed incline of 12.5% were used.
- Assess the effects on ABI of a six month treatment with Liraglutide compared to control group (standard-of-care treatment). [ Time Frame: 24 weeks ]ankle-brachial index is ratio of ankle systolic pressure to arm systolic pressure: using a 10-12 cm sphygmomanometer cuff placed just above the ankle and a doppler instrument used to measure the systolic pressure of the posterior tibial and dorsalis pedis arteries of each leg. These pressures are then normalized to the higher brachial pressure of either arm to form the ankle-brachial index (ABI). The index leg is often defined as the leg with the lower ABI.
- Assess the effects on endothelial function of a six month treatment with Liraglutide compared to control group (standard-of-care treatment). [ Time Frame: 24 weeks ]Assess the effects on endothelial function of a six month treatment with Liraglutide compared to conventional treatment, assessed as the baseline corrected change in endothelial function by flow-mediated vasodilation (FMD) of the brachial artery at 6 months.
- Muscle microvascular perfusion by CEU [ Time Frame: 24 weeks ]Contrast enhanced ultrasound (CEU) performed by experienced radiologists is used for contrast ultrasonographic examination of skeletal muscle.
- Assess the effects on the endothelial circulating progenitor cells concentration of a six month treatment with Liraglutide compared to control group (standard-of-care treatment). [ Time Frame: 24 weeks ]Circulating progenitor cells (EPCs) will be quantified using flow cytometry before and after 6 month treatment GLP-1 receptor agonist or conventional therapy (control group). Briefly, after erythrocyte lysis, peripheral blood will be stained with 10µL fluorescein isothiocyanate-conjugated anti-human CD34 mAb, 10µL phycoethrin-conjugated anti-human KDR mAb, and 10µL allophycocyanin-conjugated anti-CD133 mAb.
- Changes from baseline in HbA1c [ Time Frame: 24 weeks ]Change from baseline to last assessment during the treatment period in HbA1c
