Evaluation of Donor Specific Immune Senescence and Exhaustion as Biomarkers of Tolerance Post Liver Transplantation (OPTIMAL)


The goal of the OPTIMAL study is to gradually reduce anti-rejection medication(s) in liver transplant recipients over a period of time until the medication(s) are stopped. This is called immunosuppression withdrawal.

As part of the OPTIMAL study, investigators will also do blood and liver biopsy tests to see whether they can identify common markers of immune systems that are able to tolerate transplanted livers without immunosuppressive medications. Identification of these markers and tests will help transplant doctors predict whether it is safe to decrease or stop anti-rejection medication(s) for future liver transplant recipients.

In general, study visits will consist of a brief physical exam, and some visits will also include questionnaires as well as blood, urine, stool (fecal), and liver biopsy collections.

In total, participation may last between 3.5 and 6 years.
