Active clinical trials for "Leukemia"

The present pharmacokinetic (PK)-pharmacodynamic (PD) study will explore the toxicity and antileukemic response during the initial 3 months of individualised therapy of children and young adults with acute lymphoblastic leukemia (ALL). The investigators will on an individual toxicity-titrated basis attempt to increase the dose intensity of the 6-mercaptopurine used in the two-months post-remission treatment phase of lower risk childhood ALL. This will be performed together with continuous PEG-ASP (every 2nd week) and interspersed HD-MTX (5 g/m^2) every 3rd week. Thus, the trial will also test the feasibility of this particular drug combination.

The purpose of this study is to determine if ribavirin (a drug commonly used to treat hepatitis C) also has activity in the treatment of patients with refractory or relapsed acute myeloid leukemia (AML) of the M4 and M5 subtype.

RATIONALE: Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or stopping them from dividing. Colony stimulating factors, such as G-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine to see how well it works when given together with cytarabine and G-CSF in treating patients with relapsed or refractory acute myeloid leukemia

Due to ALL Ph+ patients should receive a different treatment, is proposed a therapeutical protocol with: intensification treatment of induction to increment the CR rate, allogenic transplantation in first CR, autologous transplantation follow by alfa interferon in patients cannot done allogenic transplantation.

The purpose of this study is to show that a therapeutic platelet transfusion strategy (i.e. platelet transfusion only in case of bleeding) needs minimally a quarter less of transfusions compared to the standard prophylactic transfusion strategy (i.e. platelet transfusion without any sign of bleeding when the platelet count is below 10.000/µL). With the experimental transfusion strategy transfusions could be safely reduced when the study hypothesis can be proven. This is the first prospective randomized study on this topic.

The goal of this clinical research study is to find the highest tolerable dose of Azacytidine (5-azacytidine) combined with cytosine arabinoside (ara-C) for the treatment of patients with relapsed and/or refractory Acute Myeloid Leukemia (AML) or high-risk Myelodysplastic Syndrome (MDS). The safety and effectiveness of this treatment combination will also be studied.

The purpose of this study is to see at what dose MDX-1342, a monoclonal antibody, is safe and tolerable for patients with chronic lymphocytic leukemia (CLL). Information on any responses that patients may have to the drug will also be collected.

This study uses a new investigational (not yet approved by the FDA for widespread use) drug called ZIO-101, an organic arsenical. You must be diagnosed to have relapsed/refractory leukemia or lymphoma (blood cancer) and have tried other standard therapies. This study is designed to determine whether ZIO-101 may be given safely. The study will also test whether ZIO-101 helps to treat blood cancer. We anticipate that approximately 22 to 35 patients will take part in this study. Arsenic has been used as a medicinal agent for centuries in many different cultures. Most recently in the United States, an inorganic arsenic compound was approved by the FDA for the treatment of patients with relapsed acute promyelocytic leukemia (APL). However, use of inorganic arsenic is limited by a narrow range of activity and systemic toxicity, most notably of the cardiac system. ZIO-101 is an organic arsenic derivative. In vitro testing in both the National Cancer Institute (NCI) cancer cell panel and in vivo testing in a leukemia animal model demonstrated substantial activity of SGLU against hematologic cancers. In vitro testing of SGLU using the NCI human cancer cell panel also detected activity against lung, colon and brain cancers, melanoma, and ovary and kidney cancers. Moderate activity was seen against breast and prostate cancers cells. Data suggest that organic arsenic generates reactive oxygen species in the cells to induce apoptosis and cell cycle arrest.

Two-arm, randomized, open-label trial designed to evaluate the efficacy and safety of bosutinib alone compared to imatinib alone in subjects newly diagnosed with chronic phase Chronic Myelogenous Leukemia (CML). The primary endpoint is cytogenetic response rate at one year.

RATIONALE: Giving an infusion of donor lymphocytes may be able to kill cancer cells in patients with hematologic cancer that has come back after a donor stem cell transplant. PURPOSE: This clinical trial is studying how well donor lymphocyte infusion works in treating patients with recurrent or persistent hematologic cancer after donor stem cell transplant.
