The purpose of this study is to test the tolerability, safety, and effectiveness of 12 weeks once-daily fenofibrate in reducing Ischemic Cholangiopathy (IC) incidence after Donation after Circulatory Death (DCD) liver transplantation. Additionally to assess the association between serum markers of cholestasis and development of IC. Tolerability and safety will be assessed as proportions of: drug discontinuation, and new grade 3 or 4 adverse events. Effectiveness will be assessed as incidence of cholangiographically-diagnosed IC and incidence of any IC-related complication.

The main focus of this study is to develop blood and/or urine tests that will help to detect early signs of rejection in people who have had a liver transplant. Researchers will examine blood, urine, and tissue samples and try to identify markers for certain conditions such as rejection, response to therapy, and scarring of the liver. Additionally, researchers would like to identify biomarkers that can detect damage to the native kidneys before blood levels of creatinine rises. By studying gene expression, researchers hope to be able to diagnose these conditions earlier and improve liver survival.

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 ...
