Epstein-Barr Virus (EBV)-Associated DiseasesEBV+ Lymphoproliferative Disease With Primary Immunodeficiency (EBV+ PID LPD)9 moreThe purpose of this study is to assess the efficacy and safety of tabelecleucel in participants with Epstein-Barr virus (EBV) associated diseases.
Acalabrutinib and Obinutuzumab for the Treatment of Previously Untreated Follicular Lymphoma or...
Grade 1 Follicular LymphomaGrade 2 Follicular Lymphoma6 moreThis phase II trial studies the effect of acalabrutinib and obinutuzumab in treating patients with follicular lymphoma or other indolent non-Hodgkin lymphoma for which the patient has not received treatment in the past (previously untreated). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of cancer cells to grow and spread. Giving acalabrutinib and obinutuzumab may kill more cancer cells.

Polatuzumab Vedotin (Pola) Plus Rituximab (R) in Patients With Post-transplant Lymphoproliferative...
Post-transplant Lymphoproliferative DisorderThis study will test polatuzumab vedotin in combination with rituximab in patients with treatment-naïve CD20-positive post-transplant lymphoproliferative disorder (PTLD) based on the established efficacy of polatuzumab vedotin in B-cell lymphomas and the inadequate response rate of PTLD to single-agent rituximab. The hypothesis is that this combination therapy will be safe, well-tolerated, and effective. If so, patients with PTLD will be able to be spared the toxicity of anthracycline-based chemotherapy. Additionally, the role of the tumor microenvironment and the role of anellovirus, a non-human pathogen virus, will be explored as prognostic markers in PTLD.
Pilot Trial of Allogeneic Blood or Marrow Transplantation for Primary Immunodeficiencies
Primary T-cell Immunodeficiency DisordersCommon Variable Immunodeficiency3 moreBackground: Allogeneic blood or marrow transplant is when stem cells are taken from one person s blood or bone marrow and given to another person. Researchers think this may help people with immune system problems. Objective: To see if allogeneic blood or bone marrow transplant is safe and effective in treating people with primary immunodeficiencies. Eligibility: Donors: Healthy people ages 4 or older Recipients: People ages 4-75 with a primary immunodeficiency that may be treated with allogeneic blood or marrow transplant Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will have urine tests, EKG, and chest x-ray. Donors will have: Bone marrow harvest: With anesthesia, marrow is taken by a needle in the hipbone. OR Blood collection: They will have several drug injections over 5-7 days. Blood is taken by IV in one arm, circulates through a machine to remove stem cells, and returned by IV in the other arm. Possible vein assessment or pre-anesthesia evaluation Recipients will have: Lung test, heart tests, radiology scans, CT scans, and dental exam Possible tissue biopsies or lumbar puncture Bone marrow and a small piece of bone removed by needle in the hipbone. Chemotherapy 1-2 weeks before transplant day Donor stem cell donation through a catheter put into a vein in the chest or neck Several-week hospital stay. They will take medications and may need blood transfusions and additional procedures. After discharge, recipients will: Remain near the clinic for about 3 months. They will have weekly visits and may require hospital readmission. Have multiple follow-up visits to the clinic in the first 6 months, and less frequently for at least 5 years.
Immune Disorder HSCT Protocol
Immune Deficiency DisordersSevere Combined Immunodeficiency12 moreThis study hypothesizes that a reduced intensity immunosuppressive preparative regimen will establish engraftment of donor hematopoietic cells with acceptable early and delayed toxicity in patients with immune function disorders. A regimen that maximizes host immune suppression is expected to reduce graft rejection and optimize donor cell engraftment.
Most Closely Matched 3rd Party Rapidly Generated LMP, BARF1 And EBNA1 Specific CTL, EBV-Positive...
Hodgkin DiseaseNon-Hodgkin Lymphoma4 moreThe 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.
Evaluation of the Efficacy of a Treatment by One Single Dose of Rituximab (375mg/m2 ) in the Prevention...
Epstein-Barr Virus InfectionsEpstein Barr virus infects over 90% of human population and persists during lifetime. After infecting B lymphocytes, EBV remains latent in memory B cells. In immunocompromised patients, primary infection could lead to an uncontrolled EBV infected B cells proliferation because of impaired T cell specific cytotoxicity. The latent EBV infection is characterized by expression of restricted latent gene products, which drive cell proliferation and progression to PTLD. As a consequence, EBV seronegativity and EBV mismatch are major risk factors for developing PTLD. The investigators reported in a previous work from the French Registry that the incidence of PTLD was multiplied by ten in adult EBV negative kidney transplant recipients. Moreover, even if the event is relatively rare after transplantation, the prognosis is severe with high morbidity and an overall mortality rate around 50%. Nowadays, few and inconsistent data exist regarding beneficial preventing strategies like antiviral therapy, reduction of immunosuppression or immunoglobulin infusion in this high-risk population of EBV negative recipients. Therefore, an efficient and safe preventive treatment is still lacking to decrease PTLD incidence. Rituximab, has been already proposed in stem cell transplant recipients as a preemptive therapy in patients with a persistent EBV viremia independently of their EBV status. A pilot study was performed in EBV negative kidney transplant recipients but in a very small population. Schachtner60 reported the cases of 5 EBV negative recipients receiving kidney from EBV positive donors after a treatment with Rituximab. Only 2 patients showed a seroconversion and no patients developed neither a viremia nor a PTLD after 49 months of follow-up. The main objective of the investigators study is to evaluate the efficacy of early infusion of Rituximab in the prevention of EBV primary infection and post-transplant lymphoproliferative disorder (PTLD) occurrence in adult EBV negative kidney transplant recipients transplanted with an EBV positive donor.
