Safety and efficacy of STI-571 (imatinib mesylate) in patients with bcr/abl-positive chronic myelogenous leukemia (CML) after autologous peripheral b…
2001
We examined safety and efficacy of STI-571 in 24 bcr/abl-positive patients with CML post PBSCT. At start of STI-571 therapy, nine patients presented in blast crisis (BC) or in accelerated phase (AP), and 15 in chronic phase (CP). Patients were evaluated for hematologic, cytogenetic and molecular response, survival and toxicity. In general, STI-571 was well tolerated in this heavily pretreated group of patients with a non-hematologic and hematologic toxicity profile similar to that observed in a previous phase I trial at comparable doses. Five of nine patients with CML in transformation (AP, BC) were evaluable for hematologic response. Two of five patients had transient reductions in WBC and…
Interferon alfa-2c in chronic myelogenous leukemia (CML): hematologic, cytogenetic and molecular-genetic response of patients with chronic phase CML …
1990
Alpha- and gamma-interferons have been shown to actively suppress hematopoiesis in patients in the chronic phase of chronic myelogenous leukemia in vitro and in vivo. Since both interferons act through different receptors on their hematopoietic target cells, they are expected to be capable of independently inhibiting abnormal blood cell development in patients with chronic myelogenous leukemia. We have utilized recombinant human interferon alfa-2c to treate 11 patients with Philadelphia chromosome positive chronic myelogenous leukemia in chronic phase, who were resistant to previous interferon gamma therapy. Ten of the patients were evaluable for hematologic, cytogenetic and molecular-genet…
High BCR-ABL Levels At Diagnosis Are Associated with Unfavorable Responses to Imatinib Mesylate.
2012
Abstract Abstract 2790 The approval of second-generation tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated a need for early molecular parameters associated with inadequate responses to Imatinib Mesylate (IM). Recent evidence suggests that CML patients presenting BCR-ABL/ABLIS levels >10% after 3 months of IM or >1% after 6 months of treatment have inferior outcomes in terms of both overall survival (OS) and progression-free survival. We wanted to establish if high BCR-ABL transcripts at diagnosis would also be associated with unfavorable responses to IM. To this end, we correlated quantitative determinations of BCR-ABL measu…
High BCR-ABL/GUSIS Levels At Diagnosis Are Associated With Unfavorable Responses To Imatinib
2013
Abstract The approval of three tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated an urgent need for molecular parameters predictive of unfavorable therapeutic outcomes. Recent evidence suggests that failure to achieve early molecular responses (i.e. BCR-ABL/ABLIS levels <10% after 3 months or <1% after 6 months of TKI treatment) results in inferior rates of both overall and progression-free survival. With the current study, we wanted to establish if high BCR-ABL transcripts at diagnosis would be associated with unfavorable responses to Imatinib Mesylate (IM). Thus, we correlated quantitative determinations of BCR-ABL levels …
Sustained Responses and Resistance to Imatinib Mesylate in the First 173 Chronic Myeloid Leukemia Patients Accrued by the SCREEN Multicenter Study: F…
2009
Abstract Abstract 4276 Introduction Imatinib mesylate (IM) has shown unprecedented effectiveness in the treatment of Chronic Myeloid Leukemia (CML) patients (pts) in the chronic phase of the disease. As most of the data concerning the efficacy of the drug derive either from a single sponsored trial or from single institution reports, we decided to accrue all CML pts diagnosed in the Italian region of Sicily to the observational SCREEN (Siciliy CML Regional Enterprise) study, to evaluate the hematological, cytogenetic and molecular responses of this unselected population to IM. Patients and Methods Although the study is still ongoing, 173 consecutive CML pts have been enrolled between Januar…
