This study examines the combined use of everolimus and imatinib mesylate in patients with chronic phase chronic myelogenous leukemia (CML) who did not achieve a complete cytogenetic response despite prior imatinib mesylate. It enrolled patients aged 18 and older who were Philadelphia chromosome positive and had been on imatinib for at least 9 months. The research was conducted in Phase 1/Phase 2 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
DISEASE CHARACTERISTICS:
* Histologically confirmed chronic myelogenous leukemia (CML)
* In chronic phase
* Philadelphia chromosome (Ph)-positive
* No accelerated or blastic phase
* Accelerated phase CML is defined as ≥ 15% but \< 30% blasts in peripheral blood or bone marrow OR ≥ 30% blasts and promyelocytes in peripheral blood or bone marrow provided that \< 30% blasts were present OR ≥ 20% peripheral basophils OR platelet count \< 100,000/mm\^3, unrelated to therapy
* No less than 20 metaphases in the bone marrow sample
* No evidence of complete cytogenetic response to imatinib mesylate (complete cytogenetic response defined as 0% Ph-positive cells in bone marrow)
* Receiving continuous imatinib mesylate therapy for ≥ the past 9 months
* Dosage ≥ 600 mg/day for ≥ the past 3 months
* Stable dose of 600 mg/day for ≥ the past 4 weeks
* Achieved and maintained hematological response to imatinib mesylate as defined by all of the following:
* WBC \< 20,000/mm\^3
* Basophils \< 20%
* Less than 5% myelocytes and metamyelocytes in peripheral blood
* No blasts or promyelocytes in peripheral blood
* No evidence of disease-related symptoms or extramedullary disease, including enlarged spleen or liver
