Descriptive Information
Brief Title  ICMJE Cell Therapy in Myocardial Infarction
Official Title  ICMJE Multicenter Prospective Randomized Double Blind Trial of Bone Marrow Mononuclear Cells Transplantation Through Intracoronary Injection in Patients With Acute Myocardial Infarction.
Brief Summary The purpose of this study is to determine cell therapy efficacy in patients with ST elevation acute myocardial infarction (STEMI)
Detailed Description

This study protocol describes a randomized double blind clinical trial, which main purpose is to evaluate the effect of the autologous bone marrow mononuclear cell (ABMMC) implant in 300 Brazilian patients with ST elevation acute myocardial infarction (STEMI).

Double blind study design was chosen for this trial, based on several phase I and II safety trials of intracoronary autologous bone marrow stem cells transplantation, already published. The study coordinator committee, supported by the Brazilian Health Ministry, therefore has proposed a phase III trial with the purpose of proving the efficacy of this kind of therapy, for a population with a high risk of developing heart failure and of death by cardiovascular cause.

Thus, in this protocol we propose a prospective, double blind, controlled and randomized trial to evaluate the effect of ABMMC transplantation through intracoronary infusion, on systolic left ventricle (LV) function. The main hypothesis of this trial is that patients submitted to autologous bone marrow stem cell implant, after 6 months follow up, will present a 5% relative increase of the ejection fraction (EF) comparing to control group.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
Double Blind Randomized Controlled Trial
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:
Control group received injection of saline with 5% autologous serum without the suspension of mononuclear cells.
Primary Purpose: Treatment
Condition  ICMJE Acute Myocardial Infarction
Intervention  ICMJE Procedure: Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation
Catheter based stem cells delivery of 100 million cells resuspended in a 10 ml solution of saline with autologous serum. About 100 ml of Bone Marrow aspirate were harvested from iliac crest between the fifth and seventh day after myocardial infarction. ABMMC were isolated by density gradient centrifugation on Ficoll-PaqueTM plus (Amersham Biosciences) and manipulated under aseptic conditions for injection, after being filtered through 100 um nylon mesh to remove cell aggregates.
Other Name: Catheter based stem cell delivery
Study Arms  ICMJE
  • Experimental: Treated Group
    Intracoronary injection in the infarcted-related artery of 100 million bone marrow mononuclear cells resuspended in a 10 ml solution of saline with autologous serum.
    Intervention: Procedure: Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation
  • Placebo Comparator: Control Group
    Intracoronary injection in the infarcted-related artery of placebo solution consisting of a saline containing autologous blood serum.
    Intervention: Procedure: Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Patients will be eligible if presenting all characteristics described below:

    • ST segment elevation myocardial infarction in two or more contiguous leads, and according to the WHO definition, at least one of the following two:

      i) Presence of chest pain. ii) Elevation of the myonecrosis markers.

    • Age between 30 and 80 years old.
    • Ejection fraction ≤50% on Echocardiogram (Simpson) and segmentary dysfunction of the infarction area, measured between the 3rd and 5th day post AMI.

Among patients submitted to thrombolytic therapy, the angioplasty of the related artery should be preferably done up to 24h after thrombolysis, with a maximum deadline of 72h after thrombolysis.

Exclusion Criteria:

  • Patients will be ineligible if presenting any of the characteristics described below:

    • AMI related artery presenting TIMI < 3 at the moment f cell injection.
    • Left Main Coronary Artery Lesion of >50% or multivessel coronariopathy (>70% lesion in vessels with >2,0mm diameter in left anterior descending, circumflex and right coronary territory) indicating the need for CABG or angioplasty with three or more stents implant.
    • Coronary anatomy, after thrombolytic reperfusion, presenting no need for angioplasty with stent implant.

    • Significant valve disease, defined as aortic stenosis (mean systolic pressure gradient across the aortic valve >50mmHg), mitral stenosis with a valvar area less than 1,5 cm,2 moderate to severe aortic and/or mitral regurgitation.
    • Chronic use of immunosuppressive agents.
    • > 2,0 mg/dl creatinine or previous dialysis treatment.
    • Presence of fever on the past 48h before injection glaring active systemic infection according to ACCP/SCCM (American College of Chest Physicians/Society of Critical Care Medicine) sepsis definition.
    • Sustained ventricular tachycardia 48h after AMI.
