Active clinical trials for "Leukemia, Myelogenous, Chronic, BCR-ABL Positive"

The purpose of this study is to assess the safety and efficiency of adding pioglitazone to chronic phase chronic myelogenous leukemia patients having received imatinib mesylate who have acquired a stable molecular response but not complete molecular response.

This study aims at evaluating the efficacy of treatment with ponatinib in patients with chronic myeloid leukemia who are in a chronic phase and who previously received treatment with imatinib but resulted to be resistant to it.

Describe the purpose of the study: This study aims to evaluate the improvement of Dasatinib-related adverse events and to evaluate the treatment effect and safety by measuring the genetic response of nilotinib with nilotinib 400mg BID for 12 months in Philadelphia chromosome-positive chronic myeloid leukemia patients intolerant to Dasatinib.

The suppression of the immune system creates a permissive environment for development and progression of cancer. One population of immunosuppressive cells that have become the focus of intense study is myeloid derived suppressor cells , immature myeloid cells able to induce immune-escape, angiogenesis, and tumor progression. Two different subpopulations have been identified and studied: granulocytic and monocytic myeloid derived suppressor cells with a different immunophenotype and immunosuppressive properties

The purpose of this study is to evaluate the hematological, cytogenetic and molecular response to continuous-use of Imatinib in children with CML Ph+.

Allogeneic stem cell transplantation, the only known curative modality for CML, was abandoned in recent years for a very effective and much less toxic targeted therapy with the tyrosine kinase inhibitors (TKIs). However, approximately one third of patients still need another treatment including stem cell transplantation. The study protocol comprised a cohort of consecutive patients with CML who received allogeneic stem cell transplantation using partial T cell depletion, with no post-transplant GvHD prophylaxis. Forty consecutive patients with CML underwent allogeneic stem cell transplantation from a matched sibling using partial T cell depletion (TCD), in a single institution. Escalated dose of donor lymphocyte infusion (DLI) was given in case of either relapse or presence of minimal residual disease (MRD) as detected by cytogenetic or molecular analysis. The purpose of the study is to decrease transplant-related toxicity.

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining imatinib mesylate and chemotherapy may kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of imatinib mesylate plus cytarabine in treating patients who have newly diagnosed chronic myeloid leukemia.

Single-center study, prospective, phase II trial. The study objectives are : To assess safety and pharmacokinetics of the combination of PIO and TKI in CML subjects who experience a loss of MMR following a first TKI discontinuation. To assess survival without loss of MMR over a 12 months period following a second TKI discontinuation in subjects who achieve or maintain < MR4.5 with the combination PIO and TKI administered for at least 6 months.

The purpose of this study is to determine whether radotinib is effective and safe for patients with chronic myeloid leukemia, chronic phase who are intolerable or resistant to prior 2 or more tyrosine kinase inhibitors.

The treatment of CML and the expected survival has been revolutionised since the introduction of tyrosine kinase inhibitors (TKIs) such as nilotinib. Despite their effectiveness, these drugs will never totally remove CML affected cells from the body. In order to achieve this goal, and potentially enable CML patients to live without the daily need for TKIs, other features of the patient's immune system may need to be harnessed. One possibility is using externally administered interferon (IFN) to augment the response induced by the TKI. This study will assess the response in terms of length of survival, detection of minimal disease levels and time until disease worsens in patients with chronic phase CML who are taking nilotinib and pegylated Interferon. Patients will commence taking nilotinib for 3 months, and once tolerated, will simultaneously be treated with injected pegIFN for up to 2 years. Patients can continue taking nilotinib beyond this time providing they are receiving benefit. Options are available for patients to decrease or increase their dose or to switch to another TKI, imatinib, to ensure a balance between drug effectiveness and minimal side effects is achieved.
