Optimal Pediatric Heart Transplant Immunosuppression With MicroRNAs

Sponsored by Northwestern University

About this study

This study aims to discover circulating microRNAs (associated with drug doses and levels) that can be used to characterize the overall immune state in pediatric heart transplant patients and predict patients that will go on to develop infection and rejection. MicroRNAs (miRs) are small, non-coding RNA molecules that regulate gene expression and serve as molecular biomarkers found in the circulation.

The study objectives will be accomplished in a prospective, multicenter observational, longitudinal cohort study that includes 100-150 Pediatric Heart Transplant (PHT) patients from the United States. Patients will be screened for eligibility and enrolled 10-50 days after PHT. Study participation will last 24 months. All patients will follow the center's standard of care surveillance schedule after transplant. Blood samples will be collected for miR evaluation at: 1. specified time intervals after transplant and 2. when a clinical event of interest occurs, including treated rejection, or infection. Research samples will be collected and used to evaluate microRNA expression as well as other biomarkers related to heart transplantation and immunosuppression medications. Additional data col…
