Active clinical trials for "Immune System Diseases"

Radiotherapy (RT) is an important option for patients with limited stage FL. The recommended approach for patients with limited stage FL by The National Comprehensive Cancer Network (NCCN) is 24Gy~30Gy consolidation RT following effective systemic therapy. There is no universal consensus for a ''standard'' RT field size in the treatment of limited stage FL. The involved-site radiotherapy (ISRT) has been treated effectively for these patients. However, the certain target volumes of ISRT need to be defined for patients with limited stage FL after effective chemotherapy.

The goal of this clinical research study is to learn if giving romidepsin before and after a stem cell transplant in combination with fludarabine and busulfan can help to control leukemia or lymphoma. Researchers also want to learn the highest tolerable dose of romidepsin that can be given with this combination. The safety of this combination and the safety of giving romidepsin after a stem cell transplant will also be studied. This is an investigational study. Romidepsin is FDA approved and commercially available for the treatment of CTCL in patients who have received at least 1 systemic (affecting the whole body) therapy before. Busulfan and fludarabine are FDA approved and commercially available for use with a stem cell transplant. The use of the combination of romidepsin, busulfan, and fludarabine to treat the type of leukemia or lymphoma you have is considered investigational. Up to 30 participants will be enrolled in this study. All will take part at MD Anderson.

The purpose of this study is to find out what effects new combinations of treatment will have this disease. New promising treatment strategies will be added to this study as they are available to be compared against the standard treatment.

This phase II trial studies how well donor cytotoxic T lymphocytes work in treating patients with malignancies with BK and/or JC virus. Cytotoxic T lymphocytes are made from donated blood cells that are grown in the laboratory and are designed to kill viruses that can cause infections in transplant patients and may be an effective treatment in patients with malignancies with BK and/or JC virus.

Stage A: To evaluate the safety and efficacy of red blood cells (RBCs) prepared with the INTERCEPT Blood System for Red Blood Cells Pathogen Reduction Treatment (PRT) in comparison to conventional RBCs in patients who require RBC transfusion support. Stage B: To provide early access to the INTERCEPT pathogen reduction system for RBC in regions where a substantial proportion of the population has been infected or is at risk of a transfusion-transmissible infection. The objectives and design of Stage B will be reassessed on the completion of Stage A, in consultation with the FDA.

The purpose of this research is to find the best dose of genetically modified T-cells, to study the safety of this treatment, and to see how well it works in treating patients with B cell non-Hodgkin lymphoma that has come back (relapsed) or did not respond to previous treatment (refractory).

The investigators will study the effects of methotrexate on blood pressure, arterial stiffness and endothelial function in patients with rheumatoid arthritis.

MERLIN is an adaptive, single arm, multi-centre, phase IIa multi-disease clinical trial. It is designed to: i) Determine dose safety of ORBCEL-C™ (selected Mesenchymal stromal cells derived from human umbilical cord) ii) Evaluate treatment activity through assessment of biomarkers (for patients treated at the highest safe dose only (HSD)) This trial will determine the Highest Safe Dose (HSD) that can be administered by observing for occurrence of dose limiting toxicity (DLT). Upon completion of this trial we hope to be able to justify and conduct separate, larger scale trials using ORBCEL-C™.

The body has different ways of fighting infection and disease. No single way is effective at 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 combines both T cells and antibodies to try to create a more effective treatment. This investigational treatment is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) 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. A gene is a unit of DNA. Genes make up the chemical structure carrying the genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells makes a piece of an antibody called anti-CD19. This antibody can flow through the blood and can find and stick to leukemia cells because these leukemia cells have a substance on their surface called CD19. Anti-CD19 antibodies have been used to treat people with leukemia but have not been strong enough to cure most patients. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood a piece of it is now joined to the surface of the T cells. Only the part of the antibody that sticks to the leukemia 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 CD19 chimeric (combination) receptor-activated T cells 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. Preliminary results of giving ATLCAR.CD19 cells to leukemia patients have been encouraging; however, many subjects receiving this treatment have experienced unwanted side effects including neurotoxicity and/or cytokine release syndrome (also referred to as cytokine storm or an infusion reaction). Cytokines are small proteins that interreact as e signals to other cells and are the way cells talk to one another. During cytokine release syndrome, too many cytokines are released and too many cells in your body react to their release. Symptoms resulting from cytokine release syndrome vary from flu-like symptoms to more severe side effects such as cardiac arrest, multi-system organ failure or death. We predict that about 50% of patients on this study will experience mild to severe cytokine release syndrome. To help reduce cytokine release syndrome symptoms in future patients, a safety switch has been added to the ATLCAR.CD19 cells that can cause the cells to become dormant or "go to sleep". The safety switch is called inducible caspase 9 or iC9. The modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. The purpose of this study is to determine whether receiving the iC9-CAR19 cells is safe and tolerable (there are not too many unwanted effects). Researchers has previously tested different doses of the iC9-CAR19. An effective dose that had the least number of unwanted side effects in patients was identified. It was planned to test this dose in more patients to learn more about its effect in the body. This type of research study is called a dose expansion study. It will allow the investigators to collect more information about the effect of this dose in treating of certain type of cancer.

This phase Ib/II trial is aimed at studying the combination of a drug named Selinexor (selective inhibitor of nuclear export) in combination with standard therapy for B cell Non-Hodgkin's lymphoma called R-CHOP. The investigators will establish maximum tolerated dose of Selinexor in combination with RCHOP and also study the efficacy of this combination for therapy of B cell Non-Hodgkin's lymphoma. Giving Selinexor plus chemotherapy may work better in treating patients with B cell non-Hodgkin lymphoma.
