Filter by:Plasma-cell post-transplantation lymphoproliferative disorders (PC-PTLD) are rare monomorphic PTLD divided into plasma cell myeloma (PCM) and plasmacytoma-like lesion (PLL) PTLD. To date, there is no exhaustive published cytogenetic data on PC-PTLD. The investigators report array-based comparative genomic hybridization (aCGH) of 10 cases of PCM and PLL-PTLD.
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.
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.
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).
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).
The administration of allogeneic third party derived LMP specific-CTLs (special peripheral blood cells from another person) that are made specific to fight EBV infection) in Children, Adolescents and Young Adults (CAYA) with EBV-associated refractory or relapsed lymphoma will be feasible ( able to be done), safe and well tolerated (no unexpected serious events will occur). In addition, potential donors who are EBV positive will be enrolled to donate peripheral blood to help build a bank of these specific EBV fighting cell lines.
Post-transplant lymphoproliferative disorders (PTLD) differ clinically from lymphoma in the general (immunocompetent) population due to their higher incidence and their frequent association with Epstein-Barr virus. Previous clinical trials have shown their remarkably good response to rituximab as well as to chemotherapy. The PTLD-1 trial demonstrated the efficacy and safety of sequential immunochemotherapy with 4 courses of rituximab IV followed by 4 cycles of CHOP chemotherapy. Compared to trials of rituximab monotherapy in PTLD, median overall survival was extended from 2.4 to 6.5 years. Compared to previous trials of chemotherapy, complications were reduced. In addition, we noted that those patients who already had a good response to the first four cycles of rituximab did better overall than those who did not. As a consequence, the PTLD-1/3 trial introduced risk-stratification in sequential treatment according to the response to the first 4 courses of rituximab monotherapy. Those patients with a complete remission went on to receive four further courses of rituximab whereas those who did not received rituximab and CHOP chemotherapy. Interim results have demonstrated that it is safe to restrict chemotherapy treatment in this manner and thus established the concept of treatment stratification based on the response to rituximab. The PTLD-2 trial is the next step in the development of this strategy. Compared to the PTLD-1/3 trial, the key difference is the use of subcutaneous instead of intravenous rituximab application. Interim results from an ongoing trial of patients with follicular lymphoma (NCT01200758) have shown that subcutaneous administration results in increased blood levels and in non-inferior remission rates. Furthermore, the stratification strategy is refined based on observations from the previous PTLD-1 and PTLD1/3 trials: Risk groups are now defined not only based on response to rituximab therapy but also on the international prognostic index (IPI, a well-established lymphoma risk score) and the transplanted organ. The major advantage of this new stratification is an extended low-risk group that is eligible for subcutaneous rituximab monotherapy: Patients with a low risk of disease progression, defined as those who achieve a complete remission after the first four courses of subcutaneous rituximab monotherapy and those with an IPI of 0 to 2 who achieve a partial remission at interim staging, will go on with rituximab monotherapy. Patients with high IPI who achieve a partial remission, patients with stable disease at interim staging and non-thoracic transplant recipients with progressive disease at interim staging will be considered high risk. These patients will go on with 4 cycles of rituximab plus CHOP chemotherapy similar to the PTLD-1/3 protocol. Thoracic transplant recipients refractory to rituximab will be considered very high risk and will go on with rituximab subcutaneous plus alternating chemotherapy with CHOP and DHAOx. The trial hypothesis is that the new protocol will improve the event-free survival, a measure integrating unfavorable events such as death, disease progression and treatment complications, particularly infections, in the low risk-group compared to the results of the PTLD-1 trial. In very high-risk patients data from the PTLD-1 and PTLD-1/3 trial have shown that the current treatment is not sufficient to control the disease. Death due to disease progression was observed in more than 80% of patients. Here, rituximab combined with alternating chemotherapy cycles of CHOP and DHAOx (+GCSF) may increase treatment efficacy with an acceptable toxicity profile. In summary, the PTLD-2 trials tests if the substitution of subcutaneous for intravenous rituximab and an updated stratification strategy that deescalates treatment for those at low risk and escalates treatment for those at very high risk can further improve the overall efficacy and safety of PTLD therapy.
This pilot phase II trial studies how well giving donor T cells after donor stem cell transplant works in treating patients with hematologic malignancies. In a donor stem cell transplant, the donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect.
The purpose of this study is collect and evaluate the clinical experience reached in Italy on the use of bendamustine alone or combined with rituximab as treatment of patients with relapsed or refractory chronic lymphoproliferative disorders.
This pilot phase II trial studies how well giving vorinostat, tacrolimus, and methotrexate works in preventing graft-versus-host disease (GVHD) after stem cell transplant in patients with hematological malignancies. Vorinostat, tacrolimus, and methotrexate may be an effective treatment for GVHD caused by a bone marrow transplant.
