This study is for patients that have been diagnosed with Epstein-Barr Virus associated Post-Transplant Lymphoproliferative Disorder (EBV-PTLD). The investigational drug in this study is tabelecleucel. Tabelecleucel is a product containing special immune allogeneic cells, called EBV-Cytotoxic T Lymphocytes (EBV-CTLs), that are made in the laboratory starting with cells from a healthy person who is immune to EBV. The purpose of this study is to test how well tabelecleucel works to treat EBV-PTLD following SOT in patients who have not responded to rituximab or rituximab plus chemotherapy treatment and to see what side effects happen. Your participation will help us to understand more about tabelecleucel. In the first 12-month period, participants will be asked to come to the clinic for an estimated 11 to 19 study visits and a minimum of 2 scans, depending on the number of cycles of treatment they are given. After treatment is done, participants will enter into the follow-up phase, and will continue to come into the clinic for scheduled check-ups for up to 24 months after the first dose of tabelecleucel was given. Participant information on the status of their disease and any new treatment will be collected for up to an additional 3 years. Participants can expect to be in this study for up to five years total.

The primary purpose of this registry is to evaluate the feasibility and clinical validation of LiverCare in liver transplant recipients, as part of post-transplant surveillance. LiverCare is an investigational panel test that includes 6 components: 1. AlloSure Liver 2. AlloMap Liver 3. AlloHeme Liver 4. iBox Liver 5. HistoMap Liver 6. AlloID. AlloSure Liver is a research test used to measure donor-derived cell free DNA in Liver transplant recipients. AlloMap Liver is a research gene expression profile test using peripheral blood to establish immune activity and is currently undergoing clinical evaluation and development. iBox Liver is an analytic platform that predicts organ outcomes after transplant using a software algorithm based on information from your medical records and is currently undergoing clinical evaluation and development. AlloHeme Liver is a diagnostic test to measure donor and recipient DNA in the blood. HistoMap Liver is a tissue-based gene expression test using tissue collected from standard of care biopsies to establish immune profiles within the organ and is currently undergoing clinical evaluation and development. AlloID is a blood test that will quantify the presence of more than 100 pathogens including standard post-transplant infectious disease screening such as Cytomegalovirus (CMV), Epstein-Barr virus (EBV), adenovirus, Human Herpesvirus 6 (HHV-6) and viral hepatitis.

This study is for subjects who have been diagnosed with recurrent or metastatic nasopharyngeal cancer. Subjects are expected to remain in the study for a minimum of 70 months. Drugs are FDA approved and is given through a vein (also called IV or intravenous). The procedures include blood and urine tests, troponin test. Risks include infection, bruising, bleeding, anemia, kidney damage, hearing loss, nausea, vomiting, numbness, pain, rash, blood in urine. You may not receive a benefit from participating in this trial, however, information learned from the trial may help other people in the future.
