Clinical Trial Summary

The purpose of this study is to investigate the effects of POL6326 (CXCR4 antagonist) as a stem cell mobilizing agent, on cardiac function and infarct size and on safety and tolerability, in patients with reperfused ST-Elevation Myocardial Infarction (STEMI).


Description:

After acute myocardial infarction and successful stent implantation patients will undergo a baseline MRI (magnetic resonance imaging) for eligibility for the study. Patients will receive POL6326 or placebo in the first week after STEMI. The primary and secondary endpoints will also be determined in a follow-up visit after 12 months. An interim analysis will be performed after 50% of the patients have completed the 4 months MRI assessment and may result in an adjustment of study size. A number of pre-specified subgroups will be investigated.

Accepts healthy volunteers No
Gender Both
Age group 18 Years to 80 Years
Eligibility Inclusion Criteria:

1. Patients with symptoms suggestive of an acute MI with ST-segment elevation or new left bundle-branch block and a rise or fall in cardiac necrosis markers.

2. Patients must be scheduled to undergo coronary angiography for the purposes of primary PCI (percutaneous coronary intervention) culminating in successful stent implantation.

3. Age between 18 and 80 years. Male and WOCBP (women of child bearing potential) willing to use highly effective methods of contraception from the time of first dose until 3 months after the last dose of the drug.

4. Markedly reduced LVEF at baseline cardiac MRI.

5. No previous occurrence of Myocardial Infarction.

6. Estimated glomerular filtration rate (eGFR) equal or higher than 40 mL/minute prior to MRI.

7. Signed Informed Consent.

Exclusion Criteria:

1. Evidence of multi-vessel coronary artery disease likely to require repeat PCI or coronary artery bypass grafting within 4 months.

2. Pulmonary oedema or cardiogenic shock requiring intubation or mechanical support at the time of the planned baseline MRI.

3. Fitted with a non-MRI-compatible cardiac pacemaker or implantable cardioverter defibrillator, or expected to require such a device within 4 months after randomisation.

4. Terminal illness or malignant disease.

5. Advanced hepatic disease.

6. Diagnosis of severe obesity which precludes MRI assessments.

7. Claustrophobia.

8. Acute systemic infection or fever.

9. Anemia (where hemoglobin levels are <10 g/dL), thrombocytopenia (platelet count <100000/µL) or coagulopathy.

10. History of multiple drug allergies or with a known allergy to the drug class of CXCR4 antagonists.

11. Pregnancy or females of childbearing potential who are not using double contraception

12. Known history of human immunodeficiency virus (HIV) infection, chronic hepatitis B or hepatitis C infection or significant active chronic inflammatory disease that requires immunosuppressive medication or regular systemic corticosteroids.

13. Patients who have participated in any investigational drug or device trial within 30 days prior to signing informed consent.

14. Patients who are unwilling or unable to abide by the study requirements.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in LVEF (left ventricular ejection fraction) as determined by MRI Difference in LVEF from baseline (after STEMI and stent procedure, before infusion of drug or placebo) and after 4 months 4 months No
Secondary Additional measures of cardiovascular function Using MRI the following parameters will also be determined: infarct size, LV volumes, regional LV function. Plasma BNP (brain natriuretic peptide) will also be determined. 4 months No
Secondary Mobilization of stem and progenitor cells Time dependent measurement of stem and progenitor cells during and after infusion of POL6326 2 days No
Secondary Pharmacokinetic outcome Measurement of plasma concentrations of POL6326 at predose and several time points after infusion. 2 days No
Secondary Safety of POL6326 by intravenous infusion Safety as measured by incidence, type and severity of adverse events (Major Adverse Cardiovascular Events (MACE), Arrhythmia) 12 months Yes
