Sustained Complete Molecular Remissions After Treatment With Imatinib-Mesylate in Patients With Failure After Allogeneic Stem Cell Transplantation for Chronic Myelogenous Leukemia: Results of a Prospective Phase II Open-Label Multicenter Study
Purpose In the era of molecular therapy of chronic myelogenous leukemia (CML) applying BCR-ABL tyrosine kinase inhibitors, the usefulness of molecular end points, in particular, quantitative polymerase chain reaction (PCR) for BCR-ABL in monitoring responses has been broadly accepted. Therefore, we have designed a prospective phase II trial in CML, which, for the first time, evaluated the feasibility and safety of molecular end points as surrogate markers to guide through a stratified treatment algorithm within a multicenter trial. Patients and Methods As a clinical model, we adopted minimal residual disease (MRD) found in relapse after allogeneic stem cell transplantation (SCT) in CML. For…
Combination Treatment with Imatinib and Mitoxantrone/Etoposide Is a Suitable Preparative Regimen before Allogeneic Transplantation in Patients with Myeloid Blast Crisis of Chronic Myeloid Leukemia.
Abstract In advanced BCR-ABL-positive leukemia, combination of chemotherapy with imatinib is expected to result in better reduction of leukemia cell load and may delay or offset clonal selection of resistant leukemia cells, thus improving the survival. We carried out a prospective phase I/II combination trial for patients (pts) with myeloid blast crisis of chronic myelogenous leukemia (CML). Pts were treated with imatinib+mitoxantrone/etoposide in four cohorts starting from mitoxantrone 10mg/m2/d and etoposide 100 mg/m2/d for 2 or 3 consecutive days and start of imatinib 600mg/d from day 15 (coh. 1 and 2) or from day 1 (coh. 3 and 4, respectively). After hematologic reconstitution following…
