Active clinical trials for "Leukemia"

Patients with refractory hematologic malignancies, including those who develop recurrent disease after allogeneic hematopoietic stem cell transplantation (HSCT) have a dismal prognosis. Historically, both regimen-related mortality and disease recurrence have been significant causes of treatment failure in this heavily pre-treated patient population. Novel therapeutic agents that target molecular signaling mechanisms and increase the sensitivity of leukemic cells to apoptosis may clearly play a role in this setting. This study hypothesizes that interrupting the SDF-1/CXCR4 axis using the selective CXCR4 antagonist plerixafor may be useful as a leukemic stem cell mobilizing agent for patients who are refractory to standard dose chemotherapy and in relapse after an allogeneic transplant. This hypothesis is based on the dependence of leukemia cells on MSCs for survival signals as described above and on the preclinical data that suggest increased efficacy by antileukemia agents when leukemia cells are separated from MSCs. In the present trial, the study proposes to add plerixafor to enhance the conditioning regimen cytotoxicity. At this time the goal is to determine the maximum tolerated dose (MTD) of plerixafor through the process of dose limiting toxicity (DLT) evaluation. Pharmacokinetic studies will be conducted. Additional studies will quantify and the content of leukemia cells and key regulatory and effector T cell populations in the bone marrow and blood before and after exposure to this medication. If the observed outcomes of this trial are promising, it could serve as a platform on which to study further use of plerixafor as a complimentary agent with conditioning as well as other chemotherapeutic regimens for patients with relapsed or refractory hematologic malignancies.

This study will assess the pharmacokinetics of nilotinib in Ph+ CML pediatric patients that are newly diagnosed or resistant or intolerant to imatinib or dasatinib or refractory or relapsed Ph+ ALL compared to the adult populations. It will also evaluate safety and activity of nilotinib as secondary objectives.

The purpose of this study is to assess the efficacy, safety and tolerability of AZD1152 alone and in combination with low dose cytosine arabinoside (LDAC) in comparison with LDAC alone in AML patients.

The purpose of the study is to find out what effects (good and bad) Gleevec® (Imatinib mesylate) combined with chemotherapy has on participants and their acute myeloid leukemia.

The purpose of this study is to determine if Revlimid will help maintain patients with acute myeloid leukemia in remission.

Primary: To determine the maximum tolerated dose and schedule of decitabine when administered as maintenance therapy after allogeneic hematopoietic stem cell transplantation (alloHSCT) performed for AML or high-risk MDS.

Primary objectives: To determine the maximum tolerated dose (MTD) of SAR103168 and to characterize the dose limiting toxicities (DLTs) in the proposed dose regimen To evaluate the pharmacokinetic (PK) profile of SAR103168 Secondary objectives: To characterize the global safety profile of SAR103168 To evaluate preliminary anti-leukemia activity To investigate the potential induction effect on CYP3A4 and persistence of this effect by using oral midazolam as a probe substrate in patients enrolled into the expanded cohort at the MTD To determine the metabolic pathways of SAR103168 and identify the chemical structures of metabolites To determine the potential impact of SAR103168 on the QTc interval in patients enrolled at the MTD

The goal of this clinical research study is to learn if the combination of clofarabine, cytarabine, and idarubicin can help to control Acute Myeloid Leukemia (AML) in patients who are between the ages of 18 and 60 years old. The safety of this study drug combination will also be studied.

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)

The goal of this clinical research study is to learn if giving granulocyte-macrophage colony-stimulating factor (GM-CSF) together with rituximab can improve the ability of rituximab to shrink or slow the growth of Chronic Lymphocytic Leukemia (CLL). The safety of this combination treatment will also be studied.
