Effects on Re-endothelialisation With Bydureon Treatment in Type 2 Diabetes Subjects

The aim of the study is to use Exenatide long-acting release (LAR) [Bydureon] to minimize vascular remodeling and neointima formation after Percutaneous Coronary Intervention (PCI) and to accelerate stent endothelialisation.

About this study

Exenatide LAR will be given as a once-weekly (s.c.) dose of Bydureon (2 mg) add on to Insulin in combination with Metformin. If patients are Insulin naïve (both groups) an initial dose of 10U (s.c.) at bedtime will be started, and further up-titrated to achieve a fP-glucose levels at 6 mmol/l. Standard care for post myocardial infarction will be given after PCI.

Primary objectives:

To test whether Bydureon, add on to Insulin Neutral Protamine Hagedorn (NPH) + Metformin, is superior vs. Insulin NPH + Metformin alone, in covered stent struts

Secondary objectives:

To test whether Bydureon, add on to Insulin NPH + Metformin, is superior vs. Insulin NPH + Metformin alone: in cardiac and endothelial functions

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients eligible for PCI with application of DES, due to ACS.
  • Patients with known or newly diagnosed T2D (type 2 diabetes is diagnosed according to current WHO criteria or by the use of anti-diabetic drugs)
  • Male and female subjects 18-80 years.
  • HbA1c (accordingly to IFCC) 47 mmol/mol - 110 mmol/mol.
  • Signed informed consent form.

Exclusion criteria

  • Type 1 diabetes (autoantibody positive).
  • Any history of receiving GLP-1 analogues or dipeptidyl peptidase inhibitors within 6 months
  • Known severe heart failure, classified as NYHA 4.
  • Active myocarditis; malfunctioning artificial heart valve.
  • History of ventricular tachycardia within 3 months before study entry; second- or third-degree atrioventricular block.
  • Supine systolic blood pressure <85 mm Hg or >200 mm Hg at screening.
  • Primary renal impairment, creatinine clearance < 45 ml/min if treated with metformin.
  • Uncorrected hypokalemia or hyperkalemia (potassium <3.5 mmol/l or >5.5 mmol/l).
  • Significant anemia (Hb < 90 g/l)
  • Severe gastrointestinal disease, including gastroparesis. As judged by the Investigator.
  • Body mass index (BMI) > 45 kg/m2.

Treatment and study plan

Bydureon

Drug

2 mg Once Weekly

Other names: Exenatide

Humulin kwickpen

Drug

Humulin kwickpen 10U QD at bedtime

Other names: Insulin Aspart

metformin

Drug

Metformin 1g BID

Other names: Biguanide

Primary outcomes

  1. The degree of non-covered stent struts by Bydureon add on to Insulin over that of Insulin as analyzed by optical coherence tomography (OCT).

    Time frame: 12 weeks

Secondary outcomes

  1. Fractional Flow Reserve (FFR)

    Time frame: 12 weeks

    FFR is a unitless index calculated as the ratio between distal coronary and aortic pressure during maximum hyperemia.

  2. Coronary Flow velocity Reserve (CRF)

    Time frame: 12 weeks

    CFR is a unitless index calculated as the ratio between the the mean transit time recorded at maximum hyperemia and at baseline using the thermodilution.

  3. Index of Microcirculatory Resistance (IMR)

    Time frame: 12 weeks

    IMR is a unitless index calculated by dividing the mean distal coronary pressure by the inverse of the mean transit time recorded using the thermodilution technique during maximum hyperemia

  4. Fractional flow reserve positive re-stenosis

    Time frame: 12 weeks

  5. Target lesion failure

    Time frame: 12 weeks

    Need of unplanned PCI in the treated stenosis or significant re-stenosis in the follow-up

  6. Acute coronary syndrome (ACS) and/or repeat revascularization

    Time frame: 12 weeks

  7. Late lumen loss/neointima thickness measured with OCT

    Time frame: 12 weeks

  8. Change in minimal lumen area by OCT

    Time frame: 12 weeks

  9. Left ventricular systolic and diastolic function assessed by echocardiography

    Time frame: 12 weeks

  10. Recovery from endothelial damage, measured by high resolution ultrasound, after PCI

    Time frame: 12 weeks

    Non-invasive ultrasound over the radialis artery after the PCI procedure using Standard 6-7F guiding catheters.

  11. Plasma markers of endothelial activation i.e., E-Selectin, VCAM-1, ICAM-1, nitrotyrosine levels

    Time frame: 12 weeks

  12. Plasma markers of inflammation i.e., CRP, IL-1β, IL-6 and IL-8.

    Time frame: 12 weeks

  13. Plasma markers of matrix remodeling enzymes i.e., MMP-2 and MMP9

    Time frame: 12 weeks

  14. Circulating endothelial progenitor cells

    Time frame: 12 weeks

  15. Gene expression (Affymetrix) e.g., transcription factors of sirtuins (SIRT) and nitric oxide synthase (NOS)

    Time frame: 12 weeks
