Clinical Trial to Assess the Efficacy and Toxicity of Induction and Consolidation With CPX-351 for Patients Aged 60 to 75 Years With Secondary or High-risk Acute Myeloid Leukemia

This protocol corresponds to a prospective, multicentre, open label, phase II study designed to evaluate the efficacy of CPX-351 in elderly patients with secondary or high-risk AML. The clinical trial is divided into pre-treatment, treatment (induction and consolidation cycles) and follow-up periods and consists of a single arm group. Patients will be enrolled at diagnosis to follow the treatment arm. After that will start induction chemotherapy with CPX-351 regimen (14 days maximum screening period). Once a patient have been evaluated for response and recovered from major complications, he/she will start second course (consolidation 1), unless the bone marrow and peripheral blood assessment is showing less than a complete response, then a second induction may be offered. If a CR or CRi is obtained after the second induction course, patients will start the third course after a rest and recovery period. Patients aged between 60 and 65 years old are recommended to undergo an allo-SCT after first consolidation if they are considered fit for this procedure and they have a full matched related or unrelated donor. Patients aged between 65 and 70 years old can be proposed for an allo-SCT in CR/CRi if they have a composite HSCT co-morbidity index /age less than 4 and a suitable fully matched related donor. In patients over 70 years old, an allo-SCT in first CR should be avoided although the decision should be taken on an individual basis. Patients with CR/CRi who are not considered for an allo-SCT, will follow 6 maintenance cycles with modified courses of CPX-351 schedule. Patients showing unacceptable toxicity along all therapeutic phases that, in consideration of the investigator, will be prematurely discontinued. All patients will be followed-up for survival. The study will be analyzed on an intention to treat basis. Bone marrow and response assessments will be done after each induction and consolidation course, and every 3 months during the first 12 months after startin
