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

Patients with chronic myeloid leukemia in imatinib induced CHR are randomized between imatinib 400 mg daily and imatinib 400 mg daily + PegIntron 30 ug weekly. Primary endpoint: To compare at 12 months between the treatment arms the rate of Major Molecular Response (=99,9% tumour reduction) at 12 months

Maintain and monitor long-term hematological and cytogenetic responses previously obtained by patients participating in the [CAMN107A2109] study

The purpose of this study is to provide patients with imatinib resistant/intolerant chronic myeloid leukemia - in blast crisis, accelerated phase and chronic phase, who have been previously enrolled to CAMN107A2109 and benefit from the treatment, with access to nilotinib (AMN107) in Poland until such time as the treatment with this drug is financed by the National Health Found in Poland (via 'therapeutic program') or for a period of 18 months, whichever comes first.

In this study participants with relapsed/refractory leukemia will be given MK-0457 in sequential cohorts and with varying treatment duration to determine the maximum tolerated dose (MTD) for MK-0457.

The EURO-SKI is a multicenter open label, uncontrolled trial estimating the persistence of molecular remission in Chronic Myeloid Leukemia (CML) patients after stopping Tyrosine Kinase Inhibitor (TKI). Main goal is the assessment of the duration of major molecular response (MMR) or better after stopping TKI therapy. Secondary goals include: Identification of clinical and biological factors affecting the persistence of complete molecular remission after stopping TKI (e.g. level of Complete molecular remission (CMR), risk score, duration of TKI treatment, type of TKI pretreatment) Evaluation of quality of life (QoL) in patients stopping TKI Evaluation of medico-economic impact of stopping TKI Estimating the number of patients in CMR who are eligible for stopping TKI therapy by setting up a screening log Time to recovery of CMR There will be no randomised comparison. Based on the experience of the STIM trial (Mahon et al., Lancet Onc 2010) we expect an overall six-month molecular-relapse-free survival probability of at least 40%. An interim analysis will be performed after a pilot phase where 200 patients have been observed for at least six months. Formally, it is planned to test the null hypothesis H0: Six-month molecular relapse-free survival probability P ≤ 40% against the alternative hypothesis H1: Six-month molecular-relapse-free survival probability P > 40%. Eligible are adult CML patients in chronic phase on TKI treatment in CMR for at least one year (> 4 log reduction of BCR-ABL transcripts on IS, TKI treatment for at least 3 years, confirmed by a PCR within a standardized CMR laboratory). Clinical and biological monitoring will be performed during 3 years: Associated scientific projects are performed. Recruitment period: 2 years; follow up: 3 years. Planned patient recruitment in main phase: n=500

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.

purpose: To conduct the relative bioavailability study of a single dose and multiple doses of imatinib mesylate capsule (Jiangsu Chia-Tai Tianqing Pharmacy Co. Ltd.) versus Glivec (Novartis Pharma Stein AG). Experimental Design： Two-period crossover design Test drug: imatinib mesylate capsule Reference drug: Glivec Sample size：20

This is a phase II trial using a non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen followed by a related or unrelated donor stem cell infusion. The primary objective is to evaluate rates of acute graft-versus-host disease (GVHD) grades II-IV and chronic GVHD with an updated GVHD prophylaxis of tacrolimus and mycophenolate mofetil (MMF) with a non-myeloablative preparative regimen in persons with hematologic malignancies.

The purpose of this study is to provide an opportunity for patients with malignancies or bone marrow failure states who lack a suitable sibling donor to undergo allogeneic hematopoietic progenitor cell transplantation using cells from unrelated individuals or cord blood registries.

After more than a decade of treating chronic myeloid leukemia (CML) with tyrosine kinase inhibitors (TKI), the discontinuation of treatment represents the expected new revolution. The investigators has recently discovered a new innate CD8+ T population in healthy subjects, the Eomes+ KIR+ CD8+ T population, with anti-tumor properties. Remarkably, these cells are numerically and functionally deficient in patients at diagnosis and then restored in patients in major molecular remission (MMR) on TKI. Our work performed in a retrospective pilot study interestingly shows a very significant increase in the proportion of CD8+ Eomes+ KIR+ T cells within total T cells in patients with prolonged success in stopping their ITK (≥ 2 years).Thus, the investigators postulate that CD8+ Eomes+ KIR+ T cells are a predictive signature of TKI arrest success in CML. The investigators will rely on a prospective translational study of this cell contingent during treatment cessation.
