Active clinical trials for "Leukemia, Lymphoid"

Chronic lymphocytic leukaemia (CLL) is the most common adult blood cancer in the United Kingdom. CLL means that many cancer cells appear in the blood, bone marrow and other tissues, for example, the spleen where some blood cells reside. Most patients with CLL have been diagnosed by chance, have no symptoms as a result of CLL, and do not need urgent treatment. However, when the cancer cells build up, people experience symptoms of CLL, and treatment is required. One of the current treatments for CLL is chemo-immunotherapy, that targets and kills cancer cells in the blood. However, this treatment does not kill all cancer cells. Some cancer cells survive by 'hiding' in the bone marrow and tissues, like the spleen, where the treatment cannot get to, this is called minimal residual disease (MRD). MRD eventually builds up and patients experience symptoms of CLL again. New approaches to detect and treat MRD are needed. Research has shown, that the number of blood cells, increases after exercise and that many of these blood cells come from the bone marrow and other tissues. This study will investigate if exercise can move CLL cancer cells that are 'hiding' in the bone marrow and other tissues into the blood, thus improving the detection of MRD. By moving cancer cells into blood, the investigators also think this will improve the way chemo-immunotherapy works. In this study, the investigators will investigate the number of cancer and natural killer (NK) cells in the blood after exercise, in three different groups of people with CLL: before treatment; during treatment; and after treatment has finished.

Neuropathic pain / peripheral neuropathy (NP/PN) is a known painful complication of vincristine (VCR) therapy; evidence supporting the best treatment plan for pediatric patients is limited. Gabapentin is frequently used for VCR-related NP/PN, with variable dosing and scheduling regimens, and with varying measures of success. The hypothesis of the study is that gabapentin will reduce the severity of NP/PN in patients receiving vincristine during treatment for ALL on the Total XVI protocol (or for those being treated "as per TOTXVI protocol"), as measured by two outcome measures: the daily dose of morphine used as needed for pain in addition to either gabapentin or placebo, as randomized, and the pain scores assessed daily.

This is a pilot feasibility study to collect preliminary data for a large-scale exergaming intervention in children undergoing maintenance therapy for Acute Lymphoblastic Leukemia (ALL). Patients, ages 5-17 years will be randomized to the intervention or non-intervention control group. The intervention will consist of 30 minute sessions of exergaming 3-5 times a week for 6 months, with weekly assessment of exercise level and phone calls by kinesiology graduate students for safety and compliance. Physical activity at baseline and at the end of study will be assessed using accelerometers. Outcome measures will include: anthropometrics, blood pressure, body composition, visceral fat, vascular function, fasting insulin, fasting glucose, LDL-cholesterol, HDL- cholesterol, triglycerides, functional mobility and endurance, and strength.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Dexrazoxane may lessen the side effects of chemotherapy. PURPOSE: Randomized phase III trial to compare combination chemotherapy with or without dexrazoxane and with or without high-dose methotrexate in patients with acute lymphoblastic leukemia or advanced lymphoblastic non-Hodgkin's lymphoma.

RATIONALE: Lithium carbonate may be an effective treatment for intestinal graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying lithium carbonate in treating patients with acute intestinal graft-versus-host-disease after donor stem cell transplant.

Ofatumumab is a fully-human monoclonal antibody that exhibits high binding affinity to an antigen on the surface of B lymphocytes. Antigen engagement by ofatumumab results in maximal B-cell killing through complement-dependent cytotoxicity and antigen-dependent cellular cytotoxicity in both antigen high- and low-expressing cells. Recent research has shown that ofatumumab-dependent B-cell depletion provides clinical benefit to subjects with CD20-positive cancers such as chronic lymphocytic leukemia (CLL). The purpose of the current study is to assess the impact of ofatumumab on electrocardiographic parameters with particular focus on cardiac repolarization (QTc interval duration) in subjects with refractory CLL. Subjects enrolled in this open-label, single-arm trial will receive ofatumumab at the highest clinical dose (2000 mg) studied or planned for study. Ofatumumab will be administered as eight weekly intravenous (IV) infusions followed by four monthly infusions, beginning in Week 13, across a 25-week treatment period. Cardiovascular effects will be evaluated during treatment through routine 12-lead electrocardiographic (ECG) monitoring. The pharmacokinetic relationship between plasma concentration of ofatumumab and its effect on QTc interval duration will be examined. Specifically, ECG assessments will be collected in triplicate at baseline, at the time of maximum ofatumumab concentrations periodically on-therapy, and at the end of treatment. After completion of the final ofatumumab infusion, subjects will continue to be followed for safety and efficacy for six months relative to the last ofatumumab dose.

This is a research study designed to look at the biological effects of two drugs on leukemia cells. In this study, we are comparing the effects of drugs called corticosteroids when used alone or with another drug called rapamycin. Rapamycin is a drug that prevents the body's immune system from working normally. It has been used for many years after kidney transplants to prevent rejection of the organ. Recent work suggests that rapamycin may also help treat leukemia and other cancers.

RATIONALE: Ondansetron may help lessen or prevent nausea and vomiting in patients undergoing stem cell transplant. PURPOSE: This phase II trial is studying how well ondansetron works in preventing nausea and vomiting in patients undergoing stem cell transplant.

This is a non-blinded, non-randomized pharmacokinetic study to determine the oral bioavailability of clofarabine, and the effect of cimetidine on clofarabine pharmacokinetics in patients with poor-risk acute leukemias and myelodysplastic syndrome (MDS).

Clofarabine (injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens. This research study of clofarabine will be used for advanced cancer in persons in which drugs are no longer effective or no reliable effective treatment is available. The purpose of this study is to find the answers to the following research questions: What is the largest dose of clofarabine that can be safely administered as an IV infusion (over at least 2 hours) once a week for 3 weeks (days 1, 8 and 15) followed by 1 week of rest and repeated every 28 days? What are the side effects of clofarabine when given on this schedule? How much clofarabine is in the blood at specific times after administration and how does the body get rid of the drug? Once the MTD/RP2D is established, patients will be enrolled at the MTD/RP2D regardless of the PK data with cardiac assessments done every other cycle. Will clofarabine help treat a specific cancer?
