The aim of this phase I/II trial is induction of anti leukemic T cell immunity in a clinical situation of "minimal residual disease". This might be a strategy to immunologically eradicate the residual leukemia cells. Patients to be included are chronic phase bcr/abl+ CML (chronic myeloid leukemia) patients in stable cytogenetic and/or molecular remission. These patients can be included if they have: 1. not achieved a CMR (complete molecular response) or 2. achieved bcr/abl < 10% on qPCR (quantitative polymerase chain reaction) (=MCyR) (Major cytogenic Response), but less than a CCyR (complete cytogenic Response). Autologous DC (Dendritic cells), generated under GMP (Good manufacturing conditions) conditions, are used as a vaccine. These DC constitutively express all putative tumor antigens. In order to ensure sufficient presentation of distinct CML-related antigens, particularly in good responders to TKIs, DC are additionally pulsed with peptides from bcr/abl, WT-1 (Wilms Tumor Protein) and proteinase-3. Monitoring of T cell reactivity against these peptides can then serve as surrogate marker for anti leukemic immunity induced by the vaccine. Vaccination is performed with 10^7 DC i.d. (intra dermal) in weeks 1, 3, 5, 8, 11, 14, 17, 20, 23 and 26. KLH (keyhole limpet hemocyanin) is used as an adjuvant for vaccine preparations in weeks 3, 5 and 8 (and 11).
Stem cell transplantation will continue to be a treatment option for patients with chronic myeloid leukaemia, despite the introduction of tyrosine kinase inhibitors. However, many patients will have received prior therapy with TKIs, including Nilotinib or Dasatinib at the time of allogeneic stem cell transplantation. While the use of Imatinib prior to stem cell transplantation seems to have no adverse impact on the outcome of allogeneic stem cell transplantation little is known on the impact of prior use of second generation TK inhibitors. Therefore this non interventional prospective study addresses this question and patients undergoing allogeneic stem cell transplantation after prior use of 2nd generation TKIs will be followed by the data office office on engraftment, treatment related mortality, relapse rate and survival, prospectively. Details on TKI therapy will be collected by the participating centers, retrospectively. This is a non interventional prospective study. There is no upper limit to the number of patients entered, but it is estimated that up to 450 patients will be included in 150 centres for this non interventional prospective study. The registry will include patients for three years plus one more year for follow up and data analysis which should then be followed-up until the projected end of the non interventional prospective study.
whether Nilotinib at the two sequential dosage forms will induce quicker and deeper response in those patients, and if FISH on PB (Peripheral blood) would be an effective way to monitor response compared to conventional cytogenetics on bone marrow (BM) sample
For patients with hematologic malignancies undergoing allogeneic myeloablative (MA) HCT with a T cell depleted graft, the infusion of naturally occurring regulatory T cells with conventional T cells (T cell add back) in pre-defined doses and ratios will reduce the incidence of acute graft vs host disease while augmenting the graft vs leukemia effect and improving immune reconstitution.
The objective is to evaluate the cytogenetic response to Dasatinib (BMS-354825) administered for 24 weeks in subjects with Imatinib resistant or intolerant chronic phase chronic myeloid leukemia (CML) once daily (QD) or twice daily. (BID)
The purpose of this clinical research study is to compare the rate of confirmed complete cytogenetic response (cCCyR) of dasatinib to imatinib therapy within 12 months after randomization in newly diagnosed chronic phase Philadelphia positive chronic myeloid leukemia (Ph+ CML) patients. The safety of this treatment will also be studied.
The first purpose of this study is to evaluate the persistence of the complete molecular remission in patients with Chronic Myeloid Leukemia after stopping imatinib treatment (determine by Reverse Transcription real-time Polymerase Chain Reaction (RT-PCR) negative for bcr-abl transcripts). The second purpose is to determine clinicals and biologicals factors associated with the persistent complete molecular remission.
Newly diagnosed pediatric patients (age < 19 years) with bcr-abl-positive CML will be treated with imatinib. Serial monitoring of treatment response is performed in one month intervals during the first three months of treatment and in three months intervals thereafter. Patients with non-response, poor response (either molecular, cytogenetic, or hematologic non-/poor response) or progress of the disease while under imatinib treatment will stop imatinib and undergo stem cell transplantation. All responders to imatinib treatment with an HLA matched donor will undergo stem cell transplantation not later than 2 years after diagnosis.
Imatinib mesylate is standard treatment of Chronic myeloid leukaemia, complete cytogenetic response is obtained in most of cases but molecular response concerned only a small part of the patients. To increase molecular response ratio we decided to increase imatinib dose to limited resistance to this drug and to add zoledronate for it anti tumoral activity to increase anti leukemic effect. We plan to accrue 37 patients in 5 centers. We will analyse molecular expression of BCR-ABL transcript after 6 months of treatment, safety, duration of response, VEGF expression and LTgd production.
