Filter by:Immunocompetent subjects with high load of Epstein-Barr virus DNA (EBV-DNA) in peripheral blood will be enrolled and prospectively followed up to track the natural histories of the chronic high load of EBV virus. The primary goal of this study is to explore the association of peripheral high load of EBV with the hematological malignancies, and second goal is to investigate the genetic mechanisms of immune escape and tumorigenesis of chronic EBV infection.
The purpose of this study is to evaluate whether virus-specific T cell lines (VSTs) are safe and can effectively control three viruses (EBV, CMV, and adenovirus) in patients who have had a stem cell transplant and also in patients that have a primary immunodeficiency disorder with no prior stem cell transplant.
A two part, Phase 1b/2 study to define a recommended Phase 2 dose of VRx-3996 in combination with valganciclovir (Phase 1b) designed to evaluate the efficacy of this combination in relapsed/refractory EBV+ lymphomas.
The purpose of this study is to determine the clinical benefit and characterize the safety profile of tabelecleucel for the treatment of Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) in the setting of (1) solid organ transplant (SOT) after failure of rituximab and rituximab plus chemotherapy or (2) allogeneic hematopoietic cell transplant (HCT) after failure of rituximab.
The purpose of this study is to investigate the immune responses associated with Epstein-Barr virus infections, and to find out the possible immunodeficiency that may be linked to severe Epstein-Barr virus infections.
Related donor Epstein-Barr Virus (EBV) specific cytotoxic T cells (CTLs) manufactured with the Miltenyi CliniMACS Prodigy Cytokine Capture System will be administered in children, adolescents and young adults with refractory EBV infection post Allogeneic Hematopoietic Stem Cell Transplantation (AlloHSCT), with primary immunodeficiencies (PID) or post solid organ transplant.

Background: The drug Nivolumab has been approved to treat some cancers. Researchers want to see if it can slow the growth of other cancers. They want to study its effects on cancers that may have not responded to chemotherapy or other treatments. Objectives: To see if Nivolumab slows the growth of some types of cancer or stops them from getting worse. To test the safety of the drug. Eligibility: People 12 and older who have Epstein-Barr Virus (EBV)-positive lymphoproliferative disorders or EBV-positive non-Hodgkin lymphomas with no standard therapy Design: Participants will be screened with: Medical history Physical exam Blood and urine tests CAT scan of the chest, abdomen, and pelvis Tumor and bone marrow biopsies (sample taken) Magnetic resonance imaging scan of the brain Lumbar puncture (also known as spinal tap) Positron emission tomography/computed tomography scan with a radioactive tracer Every 2 weeks, participants will get Nivolumab by vein over about 1 hour. They will also have: Physical exam Blood and pregnancy tests Review of side effects and medications During the study, participants will repeat most of the screening tests. They may also have other biopsies. After stopping treatment, participants will have a visit every 3 months for 1 year. Then they will have a visit every 6 months for years 2-5, and then once a year. They will have a physical exam and blood tests.
This phase II trial studies how well pembrolizumab works with capecitabine and radiation therapy in treating patients with mismatch repair deficient and Epstein-Barr virus positive gastric cancer. Monoclonal antibodies, such as pembrolizumab may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving pembrolizumab, capecitabine and radiation therapy may work better at treating gastric cancer.
Epstein Barr Virus (EBV) or Cytomegalovirus (CMV) infection results in significant morbidity and mortality in hematopoietic stem cell transplantation (HSCT) patients. HSCT patients often face opportunistic infections due to the immunosuppressive state during transplantation. Antimicrobial drugs are usually used for prophylactic purposes and for treatment after early detectable infections. Unfortunately, some patients develop resistance to such drug treatment. In addition to HSCT patient, immune compromised patient may also be victim to opportunistic infections. Many infections can be effectively managed by functional immune recovery. In this study, the safety and efficacy of microbial-specific cytotoxic T lymphocytes (CTLs) will be investigated.
The primary objective of this protocol is to provide expanded access to tabelecleucel to participants with Epstein-Barr virus-associated diseases and malignancies for whom there are no other appropriate therapeutic options, and who are not eligible to enroll in clinical studies designed to support the development and registration of tabelecleucel.
