About this study

Official title: Early Invasive Monitoring Attenuation Through Gene Expression (EIMAGE) Trial

This study is designed to evaluate the safety and efficacy of a peripheral blood mononuclear cell gene expression profiling method (AlloMap) in monitoring asymptomatic heart transplant patients for acute rejection beginning 2-6 months(≥ 55-185 days) after transplantation.

Read the detailed description

Cardiac allograft rejection is experienced by 20-50% of patients at least once during the first year after cardiac transplantation under the present immunosuppression regimens. The standard for rejection surveillance has been the endomyocardial biopsy (EMB). However, EMB is invasive, causes morbidity, and is subject to sampling error and inter-observer variability.

Gene expression profiling (GEP), with its high negative predictive value (NPV) for acute cellular rejection (ACR), appears to be well suited to identify low-risk patients who can be safely managed without routine invasive endomyocardial biopsy (EMB).

The Invasive Monitoring Attenuation through Gene Expression (IMAGE) multicenter study was conducted between the years 2005-2009 and studied patients who were >6 months-5 years post transplant. The IMAGE study demonstrated that the clinical outcome of heart transplant patients managed with AlloMap® was noninferior to patients managed with EMB. The EIMAGE study expands the time window under study to include patients who are 2 months (≥ 55 days) post-transplant. This earlier time frame of study is the primary difference between the EIMAGE study and the IMAGE study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Event-Free Survival and intravascular ultrasound (IVUS) measures

    Event-Free Survival (EFS) is a composite of: the development of hemodynamic compromise with rejection, allograft dysfunction (hemodynamic compromise without histologically confirmed rejection), death from any cause, or re-transplantation.

    IVUS co-primary endpoint: maximal intimal thickness of the coronary arteries from baseline (measured at 6 weeks ± 30 days) to month 12 of ≥0.5mm, as measured by IVUS.

    Measured: 1.5 years

Secondary outcomes (9)
  1. Time from enrollment to death from any cause, and cause of death.

    Measured: 1.5 years

  2. Number of biopsies performed.

    Measured: 1.5 years

  3. Time from study enrollment to biopsy-related complications, as well as the number and type of biopsy-related complications.

    Measured: 1.5 years

  4. QOL responses as collected from the SF-12 form

    Measured: Enrollment and one year post-transplant

  5. Biopsy-related patient preferences satisfaction using a non-validated survey

    Measured: Enrollment and one year post transplant

  6. Objective measurements of cardiac function

    Measured: 1.5 years

  7. Gene expression profiling scores and immunosuppressant doses

    Measured: 1.5 years

  8. Number of rejection episodes.

    Measured: 1.5 years

  9. Utilization of AlloMap or biopsy to manage corticosteroid weaning between month 6 and month 12 post-transplant.

    Measured: 6 months
