6 Clinical Trials for Various Conditions
This study is for patients that have a type of lymph gland disease called Hodgkin or non-Hodgkin Lymphoma or T/NK-lymphoproliferative disease which has come back or has not gone away after treatment, including the best treatment the investigators know for these diseases. Some patients with Lymphoma or T/NK-lymphoproliferative disease show signs of virus that is sometimes called Epstein Barr virus (EBV) that causes mononucleosis or glandular fever ("mono") before or at the time of their diagnosis. EBV is found in the cancer cells of up to half the patients with Hodgkin's and non-Hodgkin Lymphoma, suggesting that plays a role in causing Lymphoma. The cancer cells (in lymphoma) and some immune system cells infected by EBV are able to hide from the body's immune system and escape destruction. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. T cells have been used to treat patients with cancers. T cells, that have been trained to kill EBV infected cells can survive in the blood and affect the tumor. The investigators have treated over 80 people on studies using T cells to target these diseases. About half of those patients who had disease at the time they got the cells had responses including some patients with complete responses. The investigators think that if T cells are able to last longer in the body, they may have a better chance of killing EBV and EBV infected tumor cells. Therefore, in this study the investigators will add a new gene to the EBV T cells that can cause the cells to live longer called C7R. The investigators know that T cells need substances called cytokines to survive and the cells may not get enough cytokines after infusion into the body. The investigators have added the gene C7R that gives the cells a constant supply of cytokine and helps them to survive for a longer period of time. The purpose of this study is to find the largest safe dose of C7R-EBV T cells, and additionally to evaluate how long they can be detected in the blood and what affect they have on cancer.
This pilot phase II trial studies how well rituximab and latent membrane protein (LMP)-specific T-cells work in treating pediatric solid organ recipients with Epstein-Barr virus-positive, cluster of differentiation (CD)20-positive post-transplant lymphoproliferative disorder. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. LMP-specific T-cells are special immune system cells trained to recognize proteins found on post-transplant lymphoproliferative disorder tumor cells if they are infected with Epstein-Barr virus. Giving rituximab and LMP-specific T-cells may work better in treating pediatric organ recipients with post-transplant lymphoproliferative disorder than rituximab alone.
This phase Ib trial tests the safety and effectiveness of epcoritamab in treating patients with post-transplant lymphoproliferative disorder (PTLD) that has come back after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Epcoritamab, a bispecific antibody, binds to a protein called CD3, which is found on T cells (a type of white blood cell). It also binds to a protein called CD20, which is found on B cells (another type of white blood cell) and some lymphoma cells. This may help the immune system kill cancer cells. Giving epcoritamab may be safe and effective in treating patients with relapsed or refractory B-cell PTLD.
Solid organ transplantation is an important therapeutic option for children with a variety of end stage diseases. However, the same immunosuppressive medications that are required to prevent the child's immune system from attacking and rejecting the transplanted organ can predispose these individuals to developing a very serious cancer that is linked to Epstein-Barr virus (EBV).
A Phase 2 study to evaluate the efficacy of nanatinostat in combination with valganciclovir in patients with relapsed/refractory EBV-positive lymphomas
Subjects have a type of a lymph node cancer called Non-Hodgkin's Lymphoma (NHL) or lymphoproliferative disease (LPD), which affects their immunity, blood production, and can involve multiple other organs in the body. Their disease has come back or has not gone away after treatment. The experimental treatment plan consists of an antibody therapy called "Nivolumab" that helps the subjects' T-cells control the tumor, and special immune system cells called EBV-specific cytotoxic T lymphocytes, also a new therapy whose side effects are well studied. Some patients with NHL or LPD are infected with the virus that causes infectious mononucleosis (called Epstein-Barr virus, or EBV) before or at the time of their diagnosis. The cancer cells that are infected by EBV are able to hide from the body's immune system and escape destruction. Investigators want to see if special white blood cells, called T cells, that have been trained to kill cells infected by EBV can survive in the blood and affect the tumor. Investigators have used this sort of therapy to treat a different type of cancer that occurs after bone marrow or solid organ transplant called post-transplant lymphoma with good success. These cells are called EBV-specific cytotoxic T-lymphocytes (EBVSTs), and are effective in treating these diseases. These EBVSTs are experimental and not yet approved by the Food and Drug Administration (FDA). Sometimes it is not possible to grow these cells; or they may not last very long in the body after being given into the vein thereby having only limited time to fight the tumor. With this study, investigators aim to increase the duration of time that the T cells can last in the body and can effectively fight the cancer by using nivolumab. Nivolumab is FDA approved for treatment of other kinds of cancer like lung cancer and a skin cancer called Melanoma. The purpose of this study is to find out if EBVST cells in combination with nivolumab are safe, to learn what the side effects are, and to see whether this therapy may help patients with EBV related lymphoma or LPD.
