Filter by:The purpose of this study is to evaluate the disease free survival and the overall survival in patients with acute leukemia in first or second complete remission after administrating a CXCR4 antagonist, as a chemo sensitization strategy, plus chemotherapy as the conditioning regimen for autologous or allogeneic hematopoietic stem cell transplantation (HSCT).
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 study hypotheses is that the introduction of dose escalated thiotepa, in substitution to busulfan or melphalan, will reduce toxicity after allogeneic transplantation while improving disease eradication in patients with lymphoid malignancies not eligible for standard transplantation.
Autologous T cells engineered to express an anti-CD19 chimeric antigen receptor (CAR) with a safety switch will be infused back to patients with B cell malignancies, including lymphoma and leukemia. The patients will be monitored after infusion of anti-CD19 CAR-transduced T cells for adverse events, persistence of anti-CD19 CAR-transduced T cells and treatment efficacy. Objectives: To evaluate the safety and the efficacy of anti-CD19 CAR-transduced T cell therapy for patients with B cell malignancies. Eligibility: Patients between 1 and 85 years of age, who have relapsed or refractory CD19-expressing B-cell malignancies (leukemia or lymphoma) that have not responded to standard treatments. Patients with a history of allogeneic stem cell transplant who meet all eligibility criteria are eligible to participate. Patients must have adequate organ functions. Design: - Peripheral blood from patients will be collected for isolation of peripheral blood mononuclear cells (PBMCs), which will be transduced with a lentiviral or retroviral vector encoding anti-CD19 CAR containing a CD28 and a CD3 zeta as costimulatory domains as well as a safety switch. - Patients will receive a lymphodepleting preconditioning regimen to prepare their immune system to accept modified T cells. - Patients will receive an infusion of their own modified T cells. They will remain in the hospital to be monitored for adverse events until they have recovered from the treatment. - Patients will have frequent follow-up visits to monitor the persistence of modified T cells and efficacy of the treatment.
Recent advances in acute lymphoblastic leukemia treatment are based on a cytotoxic drug combination. Measurement of minimal residual disease in bone marrow samples at day 14 of treatment is the most powerful early predictive indicator of further relapse, and it can be applied practically to all patients with acute lymphoblastic leukemia. Even more so, it has been observed that patients who present negative minimal residual disease in bone marrow samples at day 7 during induction have a better prognosis than those achieving this at day 14. Relapse represents the main cause of treatment failure that related in the extreme with resistance to apoptosis, defining the latter as the principal mechanism of programmed cell death; it is also related with the induction of leukemic cells to senescent arrest. Pentoxifylline is a methyl-xanthine byproduct considered an unspecific inhibitor of phosphodiesterase. It inhibits nuclear factor-kappa-beta activation by different mechanisms and stimulates apoptosis induced by different drugs; thus, it can optimize the antineoplastic effect of actual treatments in order to increase the apoptosis of leukemic cells. This effect might improve the prognosis of these patients. Evaluate the safety and effect of Pentoxifylline together with antineoplastic drugs in order to study increased apoptosis and decreased senescence during the remission induction phase in pediatric patients with newly diagnosed acute lymphoblastic leukemia. To achieve this propose, we will divide patients in two groups, who will receive pentoxifylline or placebo depending on the group, in addition to conventional treatment according to the protocol standard chemotherapy schema for pediatric patients with acute lymphoblastic leukemia at our institution during the remission induction phase. In addition, we will test whether the study group exerts an impact on reaching remission earlier as compared with the control group.
This phase I/II trial studies the side effects and best dose of ONC201 and to see how well it works in treating patients with acute leukemia or high-risk myelodysplastic syndrome that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). ONC201 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Recently, a novel assay for detecting heavy/light chain (HLC) ratios has been reported which enables improvement in paraprotein detection and monitoring in multiple myeloma and other plasma-cell dyscrasias. The prognostic and biological role of the HLC assay has as yet not been studied in CLL. Aims of the proposed study: 1. To quantify and analyze the prognostic significance of HLC ratios in the serum of CLL patients. (In addition to FLC) 2. To study the different patterns of Immunoglobulin's subclass antibodies in the serum of patients with CLL and compare them to those of to healthy volunteers. 3. To perform a sub-analysis in patients with CLL who have autoimmune phenomenon (AIHA and ITP)
Taking into account the specificities of adolescent and young adult cancer patients led agencies (in particular the French National Cancer Institute INCa, through the last Cancer Plan), to initiate projects targeting this population. Acute leukemia is among the most common cancers in adolescents and young adults. Recent therapeutic advances now allow hope for a cure in about 50% of this population. The issue of post-cancer is therefore of particular importance for young adults with cancer. Our aim is to establish the health determinants in young adult leukemia survivors and to compare the frequency of these effects and their explanatory factors to the data collected in children or adolescent leukemia survivors program (LEA). 90 patients followed up at the Institut Paoli-Calmettes cancer center and Nice University Hospital have been identified and would be included in this study.Collected data will include information on the initial disease and its treatments, physical sequelae (fertility, thyroid function, heart function, visual function, secondary tumors, viral infections, lung function, bone metabolism, iron metabolism, metabolic syndrome, osteonecrosis, alopecia ... ), quality of life, social and occupational integration and relationship with care system.
Treatment of pediatric acute lymphoblastic leukemia (ALL) has advanced and the overall survival exceeds 80% nowadays. However the overall survival of high risk ALL remains 75-90%, thus recent studies focus on treatment intensification according to the risk group. According to the previous reports, we designed a multicenter prospective trial for pediatric ALL.
The stud will evaluate whether infusions of CD45RA-depleted lymphocytes from the donor early post-transplant is a safe way to improve immunity to common infections in recipients of TCR-alpha/beta depleted hematopoietic stem cell grafts.
