Filter by:This is an open-label study of Clofarabine, Etoposide, Cyclophosphamide, PEG-asparaginase, and Vincristine to assess this 5-drug treatment's safety and tolerability in pediatric patients with first relapse Acute Lymphoblastic Leukemia (ALL).
This is an open-label, single arm study. Approximately 3-30 patients will be enrolled. Patients will receive Oral ciclopirox olamine (aqueous suspension), initial starting dose of 5 mg/m2/day administered as a single dose daily for 5 days. Three patients will initially be treated at each dose level in sequential cohorts. Dose escalation will continue for each subsequent cohort based on toxicity and plasma drug concentrations observed during the previous cohort. Dose escalation will continue until establishment of the maximum tolerated dose (MTD) has been met. Patients who have demonstrated response to treatment, up to 6 total cycles of treatment may be administered. If additional cycles are warranted, ciclopirox olamine will be given at the same dose and frequency as the patient initially received.
The goal of this clinical research study is to test the safety of giving clofarabine in combination with busulfan, followed by an allogeneic (from a donor) stem cell transplant, in patients with advanced leukemia or lymphoma.
This phase I trial studies pretargeted radioimmunotherapy and donor peripheral blood stem cell transplant employing fludarabine phosphate and total-body irradiation (TBI) to treat patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells. Radiolabeled monoclonal antibodies can be combined with fludarabine phosphate and TBI to find cancer cells and kill them without harming normal cells. Pretargeted radioimmunotherapy (PRIT) allows for further improved targeting of tumor cells over standard directly labeled antibodies.
Background: - Allogeneic hematopoietic stem cell transplantation (allotransplant) has been used to treat many kinds of cancer that develop in cells from the blood or immune system. After allotransplant, donor cells take over production of the recipient s blood and immune cells, and donor immune cells can directly attack and control tumor. However, for cancers that do not respond to allotransplant, there are no proven cures. - A single treatment with radiation can improve the potency of immune-cell therapies. This is probably because the tumor tissue is damaged in a way that new tumor proteins are exposed, attracting immune cells to the tumor. By giving only a single dose of radiation, the immune cells that are attracted to the tumor are allowed to survive and function in their usual way, traveling throughout the body and educating other immune cells to recognize tumor, and to activate and expand in order to kill the tumor cells. Some research has shown that radiation may have a widespread effect on stimulating the immune system, educating immune cells to recognize and control tumors that have not been radiated. Objectives: - To determine whether a single treatment of radiation will help donor immune cells control cancer after allotransplant without causing excessive side effects. Eligibility: - Recipients: Individuals 18 years of age and older who have blood cancers that have not responded to allotransplant. - Donors: Healthy individuals 18 years of age and older who were previous allotransplant donors for one of the study recipients. Design: - Donors will provide additional blood immune cells, called lymphocytes, through apheresis. Apheresis involves drawing blood, separating out the lymphocytes, and returning the rest of the blood to the donor. - Recipients will receive a single dose of radiation to the greatest amount of tumor that can be irradiated safely. Researchers will intentionally leave some tumor that will not be radiated in order to evaluate whether there is a widespread response to the treatment. - There are two treatment arms on the study. - Arm 1: Study participants who have donor lymphocytes available and who have not had major complications from the allotransplant will be given a dose of donor cells after they receive radiation, to provide an additional boost to the donor immune response. - Arm 2: Study participants who cannot receive donor lymphocytes because their donor is not available, they received an allotransplant from a partially matched relative, or they have had significant complications from the allotransplant - will receive radiation without additional donor lymphocytes. - All recipients will be followed closely for side effects and for tumor response to radiation with or without donor lymphocytes. Additional tests will be performed, including tumor biopsies, bone marrow samples, and blood draws, in order to study the immune effects of radiation and donor lymphocytes. - A separate, control group of allotransplant recipients will not receive radiation. This group will include participants whose transplant doctors plan to use donor lymphocyte therapy alone to control cancer progression. This group will donate blood immune cells through blood draws and apheresis. These cells will be examined to study the immune effects of receiving donor lymphocytes without radiation.
Clofarabine is approved by the FDA for the treatment of pediatric patients (1 to 21 years of age) with relapsed or refractory ALL. Alemtuzumab is approved by the FDA for treatment of B-cell chronic lymphocytic leukemia (B-CLL) in patients over the age of 18. These drugs have been used to treat patients with leukemia in other research studies like this one. Both drugs have individually been administered to adult patients with ALL with acceptable toxicity profiles. This study will evaluate the combination of clofarabine and alemtuzumab when administered to adult patients with relapsed or refractory ALL. Primary objectives of the study is to determine the maximum tolerated dose of clofarabine when administered with alemtuzumab, evaluate the safety of the combination, and assess for activity of the combination by evaluating response rate, effect on ALL progenitor cell population, and patients who are able to bridge to transplant.
This non-controlled multicentre phase II study is designed to assess the safety and to describe (in relation to children of higher age) the pharmacodynamics of recombinant ASNase (rASNase) for first-line treatment of infants (< 1 year of age at diagnosis) with de novo acute lymphoblastic leukaemia
The study will examine the prevalence of venous thromboembolism in children with acute lymphoblastic leukaemia treated in accordance with NOPHO ALL-2008. The investigators will prospectively study clinical symptomatic thromboses, asymptomatic central line-associated thromboses, and infections.
The purpose of this study is to compare the effects (good and bad) of the medication basiliximab in combination with cyclosporine (investigational therapy) for the prevention of a complication of bone marrow transplantation known as graft-versus-host disease (GVHD). GVHD is a complication in which the cells of the transplanted bone marrow react against organs and tissues.
The purpose of this study is to determine the safety and effectiveness of a multi-drug regimen (which includes prednisone, vincristine, cytarabine, doxorubicin, 6 mercaptopurine, and methotrexate) which is considered standard treatment for children and young adults with acute lymphoblastic leukemia (ALL), in combination with PEG-asparaginase and clofarabine to treat older adults with ALL. PEG-asparaginase has been used in chemotherapy treatment regimens for both children and adults with ALL. Clofarabine has been used in chemotherapy treatment regimens for children with ALL and has been shown to decrease the number of leukemia cells. Participants with leukemia that has an abnormal chromosome, called the Philadelphia chromosome, will also be given imatinib.
