Filter by:The purpose of this study is to find out whether adding a new drug, dasatinib, to imatinib is safe, and whether the combination of the two drugs will help decrease the number of cells that contain the Philadelphia chromosome.
The goal of this clinical research study is to see if Leukine(R) (sargramostim) improves the effectiveness of the pneumococcal vaccine, a medicine used to prevent pneumococcal pneumonia, in patients with chronic lymphocytic leukemia (CLL).
This clinical study is being conducted at multiple sites to determine the activity, safety and tolerability of XL999 when given weekly to patients with relapsed or newly-diagnosed AML. XL999 is a small molecule inhibitor against Flk1/kinase insert domain receptor (KDR), PDGFR, c-Kit, FLT3 and SRC. c-Kit and FLT3 are receptors commonly expressed on AML blasts.
RATIONALE: Giving chemotherapy, such as fludarabine phosphate, busulfan, and cyclophosphamide, and total-body radiation therapy before a donor peripheral stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether low-dose chemotherapy and total-body radiation therapy is more effective than high-dose chemotherapy in treating patients with myelodysplastic syndrome or acute myeloid leukemia. PURPOSE: This phase III trial is studying low-dose conditioning to see how well it works compared to high-dose conditioning followed by peripheral blood stem cell transplant in treating patients with myelodysplastic syndromes or acute myeloid leukemia
RATIONALE: Zoledronic acid, vitamin D, and calcium may prevent bone loss in patients who are undergoing donor stem cell transplant. PURPOSE: This randomized phase II trial is studying how well zoledronic acid works in preventing osteoporosis in patients undergoing donor stem cell transplant.
RATIONALE: Supportive care, such as healing touch, may improve quality of life in patients receiving chemotherapy for acute leukemia. PURPOSE: This clinical trial is studying how well healing touch works in treating patients receiving chemotherapy for acute myeloid leukemia or acute lymphocytic leukemia.
This phase II trial is studying how well AZD2171 works in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia. AZD2171 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer cells
Background: - AZD2171 is an experimental drug that may slow the growth of cancers by blocking angiogenesis (formation of new blood vessels). - Cancer growth is dependent on angiogenesis for nutrition. - Inhibiting angiogenesis is a new approach to cancer therapy. Objectives: - To determine the side effects of AZD2171 in children and adolescents with cancer. - To determine the highest dose of AZD2171 that can safely be given to children and adolescents with cancer. - To study how the body handles AZD2171. - To determine the effects of AZD2171 on various factors related to angiogenesis. - To determine if AZD2171 can inhibit cancer growth in children and adolescents. Eligibility: -Children and adolescents 2-18 years of age with treatment-resistant solid tumor cancers or acute myelogenous leukemia. Design: - About 40 patients may be included in the study. - AZD2171 is given by mouth in treatment cycles of once a day for 28 days. Treatment may continue unless the cancer worsens or unacceptable side effects develop. - Patients have periodic physical examinations, blood and urine tests and imaging tests (CT, X-rays, MRI) to evaluate disease throughout the course of treatment. Additional blood tests are done to study how the body handles AZD2171, to look for proteins that stimulate angiogenesis, to determine if certain blood vessel cells are affected by AZD2171, and for other research purposes. - Biopsy tissue (when available) is examined for the receptor for new blood vessel formation.
Background: - About 80% of patients with hairy cell leukemia (HCL) have tumor cells that have a protein on their surface called cluster of differentiation 25 (CD25). - The experimental drug LMB-2 is a recombinant immunotoxin that has been shown to kill leukemia and lymphoma cells with the CD25 protein. (A recombinant immunotoxin is a genetically engineered drug that has two parts - a protein that binds or targets a cancer cell, and a toxin that kills the cancer cell to which it binds.) Objectives: - To evaluate the safety and effectiveness of LMB-2 in patients with HCL whose cancer cells contain the CD25 protein. - To evaluate the effects of LMB-2 on the immune system, determine how the drug is metabolized by the body and examine its side effects. Eligibility: -Adults with hairy cell leukemia whose tumor cells have CD25 on their surface Design: - Up to 27 patients may be included in the study. - Patients receive an infusion of LMB-2 through a vein every other day for three doses (days 1, 3, 5), constituting one treatment cycle. - Patients may receive up to six treatment cycles every 4 weeks unless their cancer worsens or they develop unacceptable side effects. - Blood is drawn weekly for various tests. - Before each cycle and in follow-up visits, disease status is evaluated with a physical examination, blood tests, chest x-ray and electrocardiogram. - Before the first cycle, patients may have a computed tomography (CT) scan, echocardiogram (heart ultrasound test) and bone marrow biopsy. With the patient's permission, these tests may be repeated before other cycles also.
The purpose of this study is to compare the efficacy of dasatinib with that of high-dose (800-mg) imatinib in participants with chronic phase chronic myeloid leukemia who achieved only a suboptimal response after at least 3 months of monotherapy with 400-mg imatinib. The safety of these treatments will also be evaluated.
