ISHLT Multimodality Research on Heart Transplant Patient Care Grant

CareDx Supported By: CareDx

The grant will fund research that tests the utility of donor-derived cell-free DNA (dd- cfDNA) and gene expression profiling (GEP). The research will focus on the combination of dd-cfDNA and GEP, to further the use of multimodal surveillance strategies for heart transplant recipients.

Although rates of acute rejection have declined after solid organ transplantation, there is an unmet need to better define the molecular phenotype of rejection and provide non-invasive, precision medicine tools to better detect rejection. The standard-of-care for detecting allograft rejection is pathology-read biopsies, which suffer from sampling error, interobserver variability, and artefacts that result in often subjective and varying diagnoses of allograft rejection. Genomic medicine, including biomarkers such as donor-derived cell-free DNA may permit non-invasive and earlier detection of allograft injury and rejection, and may allow for quantitative serial monitoring of graft health and response to rejection treatment. Another genomic medicine technique for monitoring allograft function is gene expression profiling (GEP) of peripheral blood. GEP characterizes changes in gene expression (upregulation and downregulation of genes) that identify pathologic states.

GEP and dd-cfDNA, separately and in combination, show potential utility for monitoring allograft health and identifying graft injury sooner and more accurately than the standard-of-care. We seek investigators who will evaluate the value of multimodality testing for allograft surveillance through improved outcomes, reduction in mortality and mobility to patients, increased graft survival, improved quality of life and reduced costs to the health system. There is also scope for genomic medicine tools to guide immunosuppression and rejection treatment. Proposals that aim to determine if multimodality can improve outcomes through immunomodulation or guiding rejection treatment are also encouraged.

Purpose

The purpose of this grant is to fund research that supports transplantation and immunology research by testing the utility of donor- derived cell-free DNA (dd-cfDNA) and gene expression profiling (GEP) in combination for heart transplant recipients.

Grant Details

Two grants will be awarded for the funding duration of one year. The budget for each grant will be up to $40,000. One grant will be designated for research to be performed in a laboratory located in the United States, and one grant will be designated for research to be performed in a laboratory located outside the United States.
