Filter by:This study evaluates the safety and efficacy of EBV-specific T-cell lines to treat patients suffering from high EBV viral titers not responding to standard of care therapies and to treat EBV-related lymphoma. The study will recruit 6 patients to receive autologous T cells or a T cell line derived from the patient's allogeneic donor (in the case of stem cell transplant recipients), and 6 patients to receive a T-cell line prepared from a matched or partially matched related donor.
The subject has a type of cancer or lymph gland disease associated with a virus called Epstein Barr Virus (EBV), which has come back, is at risk of coming back, or has not gone away after standard treatments. This research study uses special immune system cells called LMP, BARF-1 and EBNA1- specific cytotoxic T lymphocytes (MABEL CTLs). Some patients with Lymphoma (such as Hodgkin (HD) or non-Hodgkin Lymphoma (NHL)), T/NK-lymphoproliferative disease, or CAEBV, or solid tumors such as nasopharyngeal carcinoma (NPC), smooth muscle tumors, and leiomyosarcomas show signs of a virus called EBV before or at the time of their diagnosis. EBV causes mononucleosis or glandular fever ("mono" or the "kissing disease"). EBV is found in the cancer cells of up to half the patients with HD and NHL, suggesting that it may play a role in causing Lymphoma. The cancer cells (in lymphoma) and some immune system cells (in CAEBV) infected by EBV are able to hide from the body's immune system and escape destruction. EBV is also found in the majority of NPC and smooth muscle tumors, and some leiomyosarcomas. We want to see if special white blood cells (MABEL CTLs) that have been trained to kill EBV infected cells can survive in your blood and affect the tumor. In previous studies, EBV CTLs were generated from the blood of the patient, which was often difficult if the patient had recently received chemotherapy. Also, it took up to 1-2 months to make the cells, which is not practical when a patient needs more urgent treatment. To address these issues, the MABEL CTLs were made in the lab in a simpler, faster, and safer way. The MABEL CTLs will still see LMP proteins but also two other EBV proteins called EBNA-1 and BARF. To ensure these cells are available for use in patients in urgent clinical need, we have generated MABEL CTLs from the blood of healthy donors and created a bank of these cells, which are frozen until ready for use. We have previously successfully used frozen T cells from healthy donors to treat EBV lymphoma and virus infections and we now have improved our production method to make it faster. In this study, we want to find out if we can use banked MABEL CTLs to treat HD, NHL, T/NK-lymphoproliferative disease, CAEBV, NPC, smooth muscle tumors or leiomyosarcoma. We will search the bank to find a MABEL CTL line that is a partial match with the subject. MABEL CTLs are investigational and not approved by the Food and Drug Administration.
The purpose of this study is to study the prevalence of EBV, HCMV, HHV-6 in saliva and on the toothbrush patient with periodontitis.
Epstein-Barr virus (EBV) is a member of the human herpes virus family that infects more than 95 percent of the U.S. population. Most infections occur in childhood and cause no symptoms; in adolescents and adults, EBV often causes infectious mononucleosis. It has also been associated with certain forms of cancer. Chronic Epstein-Barr virus (CAEBV) is a rare disease, primarily of children and young adults, that leads to life-threatening infections. This study seeks to identify genetic mutations responsible for CAEBV. A secondary goal is to learn more about the natural history of CAEBV. The study will examine blood and tissue samples from up to 50 patients (age 3 and above) with CAEBV and up to 150 of their relatives (age 1 and above). Autopsy samples may be included in the study. Up to 300 anonymous blood samples from the NIH Clinical Center Blood Transfusion Medicine will also be examined for comparison. No more than 450 milligrams (30 tablespoons) of blood per 8 weeks will be drawn from adult patients, and no more than 7 milliliters per kilogram of blood per 8 weeks will be drawn from patients under age 18. Local health care providers will refer patients to the study and will obtain the samples. Some patients may also be seen at the NIH Clinical Center. Those patients will have a full medical history and physical examination, along with chest X-ray, blood counts, blood chemistry, EBV serologies, and viral load. Other tests, such as CT scan or MRI, may be performed if medically indicated. Patients will be asked to undergo leukapheresis. In vitro tests on the blood or tissue samples will include analysis for proteins or genes that are involved in the immune response; cloning of portions of patient DNA; transformation of B cells with EBV; measurement of the ability of patient blood cells to kill EBV-infected cells; determination of lymphocyte subsets; and determination of antibodies to EBV or other herpes viruses. If a genetic cause for CAEBV is found, the investigators will be available to discuss the results with patients in person or by telephone. Genetic indications of risk for other diseases will also be discussed with patients.
