Active clinical trials for "Leukemia, Lymphoid"

All patients are treated according to the same therapy regimen. Therapy duration (number of cycles) and radiotherapy vary according to age group, stage and response. Chemotherapy consists of a pre-phase-treatment (for all patients) and varying A, B and C cycles. Therapy for Patients in the 18-55 Age Group Patients in stages III-IV and all patients with mediastinal tumors or extranodal involvement are administered 6 cycles (A1, B1, A2, B2, A3, B3). Chemotherapy is stopped after 4 cycles (A1, B1, A2, B2) for patients with stage I/ II if a clear CR has been achieved and there is initially no mediastinal or extranodal involvement. In cases of refractory or progressive disease after 4 cycles, study therapy is stopped. These patients are to be given salvage therapy with subsequent stem cell transplantation. Therapy for Patients older than 55 years The course corresponds to that of patients in the younger age group, but the regimen is dose reduced (A1*, B1*,A2*, B2*, A3*, B3*). Antibody therapy with anti-CD20 is to be administered on day 1 of each chemotherapy cycle (A, B). After end of chemotherapy (6 or 4 cycles) 2 more cycles of anti-CD 20 are to be administered to reach a total number of 8 resp. 6 cycles antibody therapy.

The patient receive 2 different drug combinations on this study. The first combination will consist of an intensive chemotherapy regimen (cyclophosphamide, mesna, methotrexate, doxorubicin liposomal or doxorubicin, vincristine, ARA-C (cytarabine) and dexamethasone). The second combination will consist of another intensive chemotherapy regimen (methotrexate and Ara-C [cytarabine]).

Patients with advanced chronic lymphocytic leukemia (CLL) have a poor long-term prognosis. Allogeneic stem cell transplantation (SCT) in patients with CLL has only rarely been performed in the past because the clinical outcome after myeloablative conditioning was poor, mainly due to the high treatment-related mortality. However long-term disease-free survival after allogeneic SCT has been reported. Recently it has been demonstrated by our group and others that non-relapse mortality can be reduced significantly with the use of reduced-intensity conditioning regimens. Yet, graft versus host disease (GVHD) remains an important problem in this setting. Alemtuzumab is an effective drug for the treatment of patients with advanced CLL and has been successfully applied for GVHD-prophylaxis in the setting of myeloablative and reduced-intensity conditioning regimens. The goal of the present study is to evaluate the role of alemtuzumab as part of a fludarabine-based reduced intensity conditioning regimen for allogeneic SCT in patients with advanced CLL.

The aim of the study is to evaluate if the treatment with Alemtuzumab (after I or II line chemotherapy) administered for 6 weeks followed by 4 months maintenance treatment compared to a control group can reduce disease activity/residual disease and thereby delay the reoccurrence of the CLL disease.

RATIONALE: 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 more than one drug (combination chemotherapy) may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating acute lymphoblastic leukemia. PURPOSE: This randomized phase III trial is studying different combination chemotherapy regimens to compare how well they work in treating young patients with acute lymphoblastic leukemia.

The purpose of this study is to determine the correct dose for intramuscular administration to compare the frequency of antibody formation after intramuscular administration of native E.coli asparaginase and PEG-asparaginase during two treatment courses in the treatment of childhood lymphoblastic leukemia

A randomised trial for children with acute lymphoblastic leukemia, using the detection of minimal residual disease to define risk groups, aiming to answer the questions: Can treatment be reduced without compromising efficacy in a MRD-defined low risk group? Does further post-remission intensification improve outcome for a MRD-defined high risk group? Measure the Quality of Life impact of the different treatment arms on the children and their families.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known which chlorambucil regimen is more effective in treating advanced chronic lymphocytic leukemia. PURPOSE: Randomized phase III trial to determine the effectiveness of different regimens of chlorambucil in treating patients who have advanced chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of combination chemotherapy plus steroid therapy is more effective for acute lymphoblastic leukemia or lymphoblastic non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy plus steroid therapy in treating children who have acute lymphoblastic leukemia or lymphoblastic non-Hodgkin's lymphoma.

The aim of this clinical study is to evaluate the feasibility and safety of an individualized peptide vaccination approach in patients with acute lymphoblastic leukemia (ALL). For this purpose, tumor-specific mutations are analyzed by comparative exome sequencing of tumor and healthy reference tissue. Expression of variants is further validated by RNA sequencing. In a second step, HLA-binding (human leukocyte antigen-binding) peptides derived from mutated protein sequences are selected for vaccination. The peptides are administered as a vaccination cocktail with adjuvant GM-CSF and Imiquimod over a course of 9 months and a total of 16 vaccinations. Primary objective is the de novo induction of a specific T cell response without unacceptable toxicity and acute GvHD (graft versus host disease).
