Active clinical trials for "Leukemia"

The goal of this clinical research study is to compare the effectiveness of a white blood cell transfusion with radiated cells to a white blood cell transfusion with cells that have not been radiated. The safety of this procedure will also be studied.

This phase I trial studies the side effects and best dose of giving bortezomib and romidepsin together in treating patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), indolent B-cell lymphoma, peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma (CTCL). Bortezomib and romidepsin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Azacitidine has proved prolonged overall survival in patients with high-risk MDS. Minor pilot studies have shown that treatment with Azacitidine can induce transfusion independency in previous transfusion dependent patients with low-risk MDS. This study will evaluate the effect of Azacitidine in transfusion dependent patients with low-risk MDS (IPSS low or int-1) or low risk CMML. Included patients should first have failed, or considered not being eligible to, treatment with EPO +/- G-CSF. Our hypothesis is that Azacitidine can lead to transfusion independency in this group of patients. Those patients who do not respond to treatment with Azacitidine alone, will be given treatment with the combination of Azacitidine and EPO where our hypothesis is that Azacitidine can restore sensitivity to EPO.

Patients with newly diagnosed Acute lymphoblastic leukemia after providing consent, will be screened for eligibility. Eligible patients will be treated with Vincristine (1 mg/m2 at Day 1 and Day 8), Dexamethasone 24 mg/d day 1-15 and IT at Days 1, 4, 8 and 12. At day 14 patients will be randomized in two group. BMT group who have donor and Chemotherapy group who don't have suitable donor. BMT group treated with allogenic Bone Marrow Transplantation and Chemotherapy treated with Cyclophosphamide at day 15, Daunorubicin at day 15-18, Vincristine at day 15 and 22 and Dexamethasone at day 12-28 followed by standard chemotherapy. In BMT group patients will be received CNS radiotherapy at +100 day after transplantation.

RATIONALE: Giving chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Imatinib mesylate may also stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. 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 which treatment regimen is most effective in treating acute lymphoblastic leukemia. PURPOSE: This phase II trial is studying the side effects of giving imatinib mesylate together with combination chemotherapy with or without a donor stem cell transplant and to see how well it works in treating patients with newly diagnosed acute lymphoblastic leukemia.

This is a Phase II trial conducted at multiple centers for evaluation of the pharmacodynamic activity and the overall response rate contributed by the combination agents of GTI-2040 and High Dose Cytarabine (HiDAC) in Refractory and Relapsed Acute Myeloid Leukemia (AML).

This phase II trial is studying how well dasatinib works in treating patients with unresectable or metastatic squamous cell skin cancer or RAI Stage 0-I chronic lymphocytic leukemia. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Background: Major problems with stem cell transplantation (SCT) for cancer treatment are a lack of suitable donors for patients without a human leukocyte-antigen (HLA) tissue-matched sibling and graft-versus-host disease (GVHD), a serious side effects of immune-suppressing chemotherapy that is given to bring the cancer under control before SCT. In GVHD, the patients immune system attacks the transplanted donor cells. This study will try to improve the results of SCT from unrelated HLA-matched donors using targeted immune-depleting chemotherapy to bring the cancer under control before transplantation and to lower the chance of graft rejection, followed by reduced-intensity transplant chemotherapy to make the procedure less toxic. Objectives: To evaluate the safety and effectiveness of targeted immune-depleting chemotherapy followed by reduced-intensity transplant chemotherapy in patients with advanced cancers of the blood and immune system. To evaluate the safety and effectiveness of two different drug combinations to prevent GVHD. Both regimens have been successful in preventing GVHD, but they work by different mechanisms and affect the rebuilding of the immune system after the transplant. Eligibility: People 18 to 74 years of age with advanced or high-risk cancers of the blood and immune system who do not have a suitable HLA-matched sibling. Design: All patients receive chemotherapy before transplant to treat the cancer and suppress immune function. All patients receive a conditioning regimen of cyclophosphamide for 4 days and fludarabine for 4 days before SCT to prepare for the transplant. Patients are randomly assigned to one of two combination drug treatments to prevent GHVD as follows: Group 1: Tacrolimus starting 3 days before SCT and continuing for 6 months, plus methotrexate on days 1, 3, 6, and 11 post-SCT, plus sirolimus starting 3 days before the SCT and continues for 6 months following SCT. Group 2: Alemtuzumab for 4 days starting 8 days before SCT, plus cyclosporine starting 1 day before SCT and continuing for 6 months. Patients receive the donors stem cells and immune cells 2 days after completing the conditioning regimen. Patients are followed at the clinic regularly for the first 6 months after SCT, and then less often for at least 5 years. Some visits may include bone marrow aspirates and biopsies, blood draws, and other tests to monitor disease status. A skin biopsy, oral mucosa biopsy, and saliva collection are done to study chronic GVHD. ...

This is a Phase II, open-label, non-randomized study to evaluate the safety, efficacy, and pharmacokinetics of tamibarotene in adult patients with relapsed or refractory acute promyelocytic leukemia (APL) following treatment with all-trans-retinoic acid (ATRA) and arsenic trioxide (ATO). Patients must have received and failed therapy with ATRA and ATO. Treatment may have been administered either as combination therapy or sequentially as single agents. Patients who are intolerant to either drug are eligible for this study.

Primary Objective: 1. Evaluate the ability of Cyclophosphamide, Fludarabine, Alemtuzumab, and Rituximab (CFAR) to increase the proportion of patients with <5% CD5/CD19+ cells in bone marrow to 66% following 3 courses of treatment without significantly increasing the incidence of pneumonia or sepsis compared to a historic group of patients treated with the combination fludarabine, cyclophosphamide, and rituximab (FCR). Second Objectives: Assess complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR. Evaluate molecular remission in bone marrow by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responders treated with CFAR. Assess immune parameters including blood T cell counts and subset distribution and serum immunoglobulin levels pretreatment, during treatment, and post-treatment in patients treated with CFAR.
