Active clinical trials for "Lymphoproliferative Disorders"

This study will find the maximum tolerated dose (MTD) of CYNK-001 which contain NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given post Autologous Stem Cell Transplant (ASCT). The safety of this treatment will be evaluated, and researchers will want to learn if NK cells will help in treating Multiple Myeloma.

This trial studies how well leflunomide works for the treatment of patients with CD30+ lymphoproliferative disorders that have come back (relapsed) or do not respond to treatment (refractory). Leflunomide may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

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 I trial studies the side effects and best dose of genetically modified T-cells following peripheral blood stem cell transplant in treating patients with recurrent or high-risk non-Hodgkin lymphoma. Giving chemotherapy before a stem cell transplant helps stop the growth of cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) later may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect)

This is a Phase 3 study to assess the safety and efficacy of Tadekinig alfa in patients with monogenic, interleukin-18 (IL 18) driven autoinflammation due to Nucleotide-binding oligomerization domain, leucine-rich repeat and caspase recruiting domain (CARD domain) containing 4 (NLRC4) - Macrophage activation syndrome (MAS) mutation (NLRC4-MAS mutation) or X-linked inhibitor of apoptosis (XIAP) deficiency. Because of the likelihood for pathogenic IL-18 in certain monogenic diseases, patients known to harbor deleterious mutations in NLRC4-MAS or XIAP and who have a history of ongoing inflammation will be enrolled if they have ferritin ≥ 500 ng/mL or persistent C reactive protein (CRP) elevation ≥ 2 times the upper limit of normal (ULN) and the patients should have a Modified Autoinflammatory Disease Activity Index (mAIDAI) ≥ 4.

This phase II trial studies the side effect of busulfan, fludarabine phosphate, and post-transplant cyclophosphamide in treating patients with blood cancer undergoing donor stem cell transplant. Drugs used in chemotherapy, such as busulfan, fludarabine phosphate and cyclophosphamide work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy such as busulfan and fludarabine phosphate before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving cyclophosphamide after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them.

This study will gain information about a rare disorder called KSHV-associated multicentric Castleman s disease (MCD). KSHV, a virus, causes several kinds of cancer, including some forms of MCD. KSHV stands for the Kaposi s sarcoma herpes virus, also called human herpes virus-8, or HHV-8. Researchers want to understand the biology of KSHV-MCD to identify how this disease causes illness and to find ways to treat it. There is no standard therapy effective for all cases of KSHV-MCD. The disease is often fatal, and about half the people who have it die within 2 years of diagnosis. Participants ages 18 and older may be eligible for this study. Participation entails more drawing of blood and having repeated tumor biopsies than if patients received treatment in a non-research setting. Researchers would like to learn more about the relationship of KSHV and Castleman s disease symptoms, and they want to obtain at least three biopsies in this study. There are some side effects of experimental therapy that participants may take for KSHV-MCD. Zidovudine, or Retrovir , is used at a high dose. It is given orally or through a vein, four times daily, for 7 days or longer. Zidovudine can cause nausea, vomiting, decreased bone marrow function, and decreased blood counts. Combined with valganciclovir, or Valcyte , it is likely to be more toxic to bone marrow. Valganciclovir can cause problems with bone marrow function, leading to low blood counts, sterility, and defects in a fetus. Combined with zidovudine, valganciclovir may cause more toxicity to the bone marrow. It is given twice daily for 7 days or longer. Bortezomib, or Velcade , is given for a few seconds by a rapid push through a needle into the vein. It is given twice weekly for four doses and then stopped for 1 week. Bortezomib can sometimes cause low blood pressure; it also can cause gastrointestinal problems and a low blood platelet count. Rituximab and liposomal doxorubicin are drugs given by a catheter into a vein. Interferon-alpha is given by injection into the skin. Those drugs are not experimental, but their use in Castleman s disease is experimental. Some participants may be treated with a combination of chemotherapy followed by interferon-alpha. Interferon-alpha is infected into the skin by a needle. The natural form of interferon is produced by the body and helps to control viral infections. KSHV decreases the effect of the body s interferon, and the researchers want to see if giving higher doses of interferon will help to control KSHV infection. A positron emission tomography (PET) scan, for research purposes only, may be done up to three times a year. A radioactive sugar molecule called fluorodeoxyglucose, or FDG, is used. It is believed that activated lymphocytes that may be found in participants disease might use more FDG because these cells burn more glucose fuel. This study may or may not have a direct benefit for participants. However, detailed assessments made throughout the study may provide information to help the doctors treat KSHV-MCD better.

The TEAMMATE Trial will enroll 210 pediatric heart transplant patients from 25 centers at 6 months post-transplant and follow each patient for 2.5 years. Half of the participants will receive everolimus and low-dose tacrolimus and the other half will receive tacrolimus and mycophenolate mofetil. The trial will determine which treatment is better at reducing the cumulative risk of coronary artery vasculopathy, chronic kidney disease and biopsy proven-acute cellular rejection without an increase in graft loss due to all causes (e.g. infection, PTLD, antibody mediated rejection).

This phase II trial studies how well pembrolizumab works in treating patients with B-cell non-Hodgkin lymphoproliferative diseases that have not been treated. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase I trial studies the side effects and best dose of cellular immunotherapy following chemotherapy in treating patients with non-Hodgkin lymphomas, chronic lymphocytic leukemia, or B-cell prolymphocytic leukemia that has come back. Placing a modified gene into white blood cells may help the body build an immune response to kill cancer cells.
