Filter by:This study is designed to see if children with acute lymphoblastic leukemia who have developed foot drop during treatment for their leukemia consume less oxygen when walking with or without an ankle brace designed to support their foot during walking. In this study children with foot drop are asked to walk for six minutes with and without brace on their ankle. During each walk, the amount of oxygen used is measured. The child wears a face mask which is attached to a device that records how much oxygen they use. The amount of oxygen used during the walk with the brace on will be compared to the amount of oxygen used with the brace off.
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.
In this trial the investigators seek to determine if injecting cord blood cells directly into the bone marrow (intraosseous injection), rather than infusing them intravenously, can improve engraftment. The rational for doing this is that most hematopoietic stem cells (HSCs) infused intravenously never reach the bone marrow, getting trapped by other organs, such as the lungs, instead. The potential advantage of intraosseous infusion is suggested by studies in rodents that have demonstrated that in HSC transplants where the cell dose is limiting intraosseous injection is a more effective route of administration. The safety of intraosseous injections, in general, is underscored by the vast experience using intraosseous injections for resuscitation of critically ill children. The safety of injecting HSCs intraosseously has been demonstrated in a clinical trial of transplanting bone marrow cells. To safeguard against problems that might result, if intraosseous infusion fails to improve engraftment in this trial, the investigators will integrate a recently introduced strategy proven to improve engraftment-the transplantation of two cord blood units. Transplanting two unrelated cord blood units by intravenous infusion has been shown to improve engraftment (although there is still room for improvement). In this trial one unit will be injected intraosseously and the other unit will be infused intravenously. This study is being conducted as a forerunner to a larger, multi-center trial. The investigators intend to enroll five patients over 1-2 years.
This is an open-label, single arm phase 1 study to evaluate the dose-limiting toxicity, maximum tolerated dose, and recommended phase II dose of Clioquinol in patients with relapsed or refractory hematologic malignancies. The study will also characterize Cliquinol's safety, tolerability and pharmacodynamic effect.
This is an open-label phase I/II study that will investigate the combination of dasatinib and rituximab therapy in patients with relapsed/refractory CLL. In phase I, eligible subjects will take either 100 mg or 140 mg of dasatinib daily along with rituximab on day 1 of each cycle for 6 cycles. In phase II, eligible subjects will all receive the same dose of dasatinib, as established in the phase I portion, along with rituximab on day 1 of each cycle for 6 cycles. The investigators hypothesize that the combination of dasatinib and rituximab will demonstrate efficacy in the treatment of patients with relapsed/refractory CLL.
This phase I trial is studying the side effects and best dose of alemtuzumab when given together with bendamustine hydrochloride in treating patients with relapsed chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that did not respond to fludarabine phosphate. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as alemtuzumab, can also block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving bendamustine hydrochloride together with alemtuzumab may kill more cancer cells.
This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation and rituximab works in treating patients with B-cell lymphoma or chronic lymphocytic leukemia who are undergoing an allogeneic (donor) bone marrow transplant. The type of bone marrow transplant is a less intensive or "mini" transplant using a relative as the bone marrow donor. The donated bone marrow stem cells may replace the patient's immune system cells and help destroy any remaining cancer (graft-versus-tumor effect). Patients undergoing this type of transplant often have more than one relative who could be a donor. The trial is also studying a new way of choosing amongst possible donors which might improve how the rituximab works.
The primary objective is: - To determine the efficacy and safety of DepoCyte®, as the only intrathecal (IT) prophylaxis of neuromeningeal relapse for patients between 16 and 30 years old diagnosed with acute lymphoblastic leukemia of standard risk treated with the PETHEMA LAL-RI-08 Protocol Chemotherapy schedule. The secondary objectives are: - To evaluate the tolerability of IT DepoCyte® as CNS prophylaxis of CNS via IT for patients between 16 and 30 years old with ALL of standard risk. - To compare the frequency of relapse in CNS for patients between 16 and 30 years old with standard risk ALL treated with the PETHEMA LAL-RI-08 Protocol Chemotherapy schedule and receiving DepoCyte® as the only IT CNS prophylaxis, with that observed in an historic group of patients of identical risk that were treated with the PETHEMA LAL-RI/96 protocol (same systemic chemotherapy and double administration of triple intrathecal chemotherapy) - To evaluate the frequency of systemic relapses of standard risk ALL patients between 16 and 30 years old treated with the PETHEMA LAL-RI-08 Protocol and who receive DepoCyte® as the only IT prophylaxis of CNS involvement and to compare with those observed in the identical risk patients treated with PETHEMA LAL-RI/96 protocol (same systemic chemotherapy and double administration of triple IT chemotherapy)
This is a Phase II, open label, fixed dose, repeat injection, single institution study. Eligible subjects will receive up to six doses of Ad-ISF35 injected directly into a selected lymph node under ultrasound guidance. The primary goal is to determine and monitor clinical and biological responses in patients treated with repeat intranodal injections of Ad-ISF35.
