Filter by:This is an open-label, multi-center, prospective, single arm phase 2 trial of the combination of bendamustine and rituximab in patients with PTLD, monomorphic cluster of differentiation antigen 20(CD20) positive DLBCL. The investigators want to investigate the efficacy and safety of the combination of bendamustine and rituximab in patients with previously untreated PTLD, monomorphic CD20 (+) diffuse large B-cell lymphoma.
The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to cure most patients. This study is designed to combine both T cells and antibodies to create a more effective treatment called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD30 antigen (ATLCAR.CD30) administration. In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. The new gene that is put in the T cells in this study makes an antibody called anti-CD30. This antibody sticks to lymphoma cells because of a substance on the outside of the cells called CD30. Anti-CD30 antibodies have been used to treat people with lymphoma, but have not been strong enough to cure most patients. For this study, the anti-CD30 antibody has been changed so that instead of floating free in the blood it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD30 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. The purpose of this research study is to establish a safe dose of ATLCAR.CD30 cells to infuse after lymphodepleting chemotherapy and to estimate the number patients whose cancer does not progress for two years after ATLCAR.CD30 administration. This study will also look at other effects of ATLCAR.CD30 cells, including their effect on the patient's cancer.

In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the patient's genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD30. This antibody floats around in the blood and can detect and stick to cancer cells called lymphoma cells because they have a substance on the outside of the cells called CD30. Anti-CD30 antibodies have been used to treat people with lymphoma, but have not been strong enough to cure most patients. For this study, the anti-CD30 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. Only the part of the antibody that sticks to the lymphoma cells is attached to the T cells instead of the entire antibody. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD30 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. The purpose of this research study is to determine a safe dose of the ATLCAR.CD30 cells that can be given to subjects after undergoing an autologous transplant. This is the first step in determining whether giving ATLCAR.CD30 cells to others with lymphoma in the future will help them. The researchers also want to find out what side effects patients will have after they receive the ATLCAR.CD30 cells post-transplant. This study will also look at other effects of ATLCAR.CD30 cells, including their effect on your cancer and how long they will survive in your body.
This pilot clinical trial studies Salvia hispanica seed in reducing the risk of returning disease (recurrence) in patients with non-Hodgkin lymphoma. Functional foods, such as Salvia hispanica seed, has health benefits beyond basic nutrition by reducing disease risk and promoting optimal health. Salvia hispanica seed contains essential poly-unsaturated fatty acids, including omega 3 alpha linoleic acid and omega 6 linoleic acid; it also contains high levels of antioxidants and dietary soluble fiber. Salvia hispanica seed may raise omega-3 levels in the blood and/or change the bacterial populations that live in the digestive system and reduce the risk of disease recurrence in patients with non-Hodgkin lymphoma.
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.
Background: 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.
Many genetic diseases of lymphohematopoietic cells (such as sickle cell anemia, thalassemia, Diamond-Blackfan anemia, Combined Immune Deficiency (CID), Wiskott-Aldrich syndrome, chronic granulomatous disease, X-linked lymphoproliferative disease, and metabolic diseases affecting hematopoiesis) are sublethal diseases caused by mutations that adversely affect the development or function of different types of blood cells. Although pathophysiologically diverse, these genetic diseases share a similar clinical course of significant progressive morbidity, overall poor quality of life, and ultimate death from complications of the disease or its palliative treatment. Supportive care for these diseases includes chronic transfusion, iron chelation, and surgery (splenectomy or cholecystectomy) for the hemoglobinopathies; prophylactic antibiotics, intravenous immunoglobulin, and immunomodulator therapies for the immune deficiencies; and enzyme replacement injections and dietary restriction for some of the metabolic diseases. The suboptimal results of such supportive care measures have led to efforts to implement more aggressive therapeutic interventions to cure these lymphohematopoietic diseases. The most logical strategies for cure of these diseases have been either replacement of the patient's own hematopoietic stem cells (HSC) with those derived from a normal donor allogeneic bone marrow transplant (BMT) or hematopoietic stem cell transplant (HSCT), or to genetically modify the patient's own stem cells to replace the defective gene (gene therapy).
In many countries, numerous steps are taken to minimize the risk of infection from transfused blood products. Typically, blood banking organisations will screen for an array of infectious pathogens as part of their quality control protocol. While transmission of these tested agents via transfusion has become exceedingly rare, the risk of transfusion-transmitted infections for which testing is not currently performed continues to be a concern. Among these untested infectious agents is Epstein-Barr virus (EBV, also known as human herpesvirus-4). Most notably, infection with this virus in transplant recipients can give rise to a malignant disorder called post-transplant lymphoproliferative disease (PTLD), a life-threatening complication which is due to the uncontrolled expansion of EBV-infected cells. It is also associated with other complications such as hepatitis, hemophagocytic syndrome, etc. in transplant population. It is recognised that EBV infection can occurred in transfused immune suppressed graft recipients but the origin of the viral infection is still a matter of debate. It is a known fact that the EBV already present in the recipient's blood can undergo reactivation due to immune suppression. However, because it is known to occur more frequently in patients who are EBV-seronegative at the time of transplant, it is also accepted that primary infection contracted via an infected graft can be a source of virus. The question we are seeking to answer is whether immune suppressed graft recipients can acquire primary EBV infection via transfusion of blood products. EBV is present in the blood of most adults and cases of EBV transfusion-related infection have been reported. Transplant populations are generally transfused with very large volumes of blood products and our recent pilot study supports the possibility that transfusion-related EBV infection can be transmitted to pediatric hematopoietic stem cell (HSCT) recipients (Trottier et al, 2012). The aim of this study is to analyse the risk of EBV transmission through blood product transfusion in pediatric allogeneic HSCT patients.
This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.
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.
