Active clinical trials for "Leukemia, Lymphoid"

This phase I/II trial is studying the side effects and best way to give nilotinib when given alone or sequentially after imatinib mesylate after donor stem cell transplant in treating patients with acute lymphoblastic leukemia or chronic myelogenous leukemia. Nilotinib and imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving dasatinib together with combination chemotherapy may kill more cancer cells.

RATIONALE: Classical chemotherapy does not cure advanced chronic lymphocytic leukemia (CLL) despite new drugs. Rituximab is a monoclonal antibody directed against CD20 surface antigen on B lymphocytes and leads to apoptosis of CD20 positive B lymphocytes. The highest response rate yet published in the treatment of first-line CLL has been obtained by the association of fludarabine, cyclophosphamide and rituximab (FCR). Now, the question is whether this response can be improved, as some trials showed that eradication of minimal residual disease (MRD) in CLL is associated with a longer treatment-free and overall survival. Maintenance therapy using rituximab has been recently approved as a means of prolonging remission in patients with indolent non Hodgkin's lymphoma. Maintenance therapy with rituximab could be of interest in treatment of MRD in CLL and prolonging remission and survival times. PURPOSE: The overall purpose of the study is to determine the value of immunotherapy maintenance with single agent rituximab in comparison with no further treatment (observation ) for previously untreated chronic lymphocytic leukaemia in elderly (>65 years) patients who respond to induction immunochemotherapy with FCR.

Studies have shown that both high-dose Methylprednisolone and Rituximab used as single agents are effective in relapsed and refractory B-CLL. Methylprednisolone acts independently of p53 apoptosis pathway. The combination of both drugs may improve response and outcome in previously treated high-risk B-CLL patients. Study Objectives Primary: To determine the clinical benefit of high-dose Methylprednisolone and Rituximab in previously treated high-risk B-CLL patients in terms of clinical and flowcytometric response rate. Secondary: To determine progression free and overall survival. To characterize the safety profile of high-dose Methylprednisolone and Rituximab.

The purpose of this study is to evaluate the safety of GCS-100 and the biologic activity of GCS-100 in subjects with chronic lymphocytic leukemia.

This single arm study will assess the efficacy and safety of rituximab in combination with fludarabine and cyclophosphamide, followed by rituximab maintenance therapy, as first line treatment of participants with CLL.

The purpose of this study is to determine whether the bispecific T-cell engager (BiTE®) Blinatumomab (MT103) is effective in the treatment of ALL patients with minimal residual disease.

To determine the highest dose of study drug that can be taken without causing serious side effects in patients with advanced cancer. The study will look at safety of the study drug and whether the treatment schedule is tolerated by patients.

Open label multicenter, two-step, non-randomized (pilot) study to analyze the safety of 4 cycles of 3-day 40mg/m2 oral fludarabine with simultaneous thrice weekly application of 30mg alemtuzumab s.c. in patients with B-CLL disease in 1st and 2nd relapse after any primary treatment or with disease refractory to any therapy in 1st or 2nd line (including Fludarabine, ). This regimen is preceded by an escalation phase with 3-10-30 mg of alemtuzumab s.c. After the first phase (completed treatment of 7 patients) an interim analysis of safety and efficacy will be performed. In case of a sufficient risk benefit assessment followed by the enrollment of further 21 patients. Final analysis of safety and preliminary efficacy will be based on all patients enrolled.

This phase I/II trial will combine fludarabine, rituximab, and lenalidomide in untreated or minimally treated (Phase I only) CLL patients, employing fixed doses of fludarabine and rituximab, using a schedule similar to that examined by investigators at MD Anderson (J Clin Oncol 23(18):4079-88, 2005). Given that the optimal dose and schedule is not currently known, this trial will perform a phase I component followed by a phase II examination to further explore this regimen's activity.
