Clinical Trials

The purpose of this study is to describe the association between Prospera dd-cfDNA measures and other diagnostic tests used to detect heart allograft rejection and/or njury, including histology, echocardiography and DSA, in the first post-transplant year. Additionally, to inform rates of clinical outcomes in a contemporary cohort of adult heart transplant recipients to determine power for a future randomized, controlled clinical trial.

Nonadherence to immunosuppression is associated with an increased risk for organ rejection, allograft vasculopathy, and death (De Geest et al., 2014). Immunosuppression nonadherence has been found to be a factor in up to 90% of late acute rejection events that occur after the first year following transplant, and in 13% to 26% of deaths among heart transplant recipients in single-center research studies (De Geest et al., 2005). A prospective cohort study found that for individuals who were nonadherent after their first year following transplant, the risk of a negative clinical event was doubled (Dobbels et al., 2004). In ...
