简要总结
Primary outcome measure:
Evaluate the efficacy in terms of complete responses of induction therapy and first-line consolidation of Clofarabine and low-dose Cytarabine with AML patients aged 60 years or more. The first efficacy objective is evaluate the overall remission rate (TRG), where general reference (RG) is defined as a patient who achieved complete remission (CR) or complete remission with inadequate platelet recovery (CPR).
Secondary outcome measures:
- To evaluate disease-free survival (DFS)
- Evaluate the overall survival (OS)
- To evaluate the safety and tolerability of clofarabine and duration, severity and relationship of adverse events (AEs) occurring during treatment
- To assess the rate of mortality at 30 days (ie, the incidence of deaths occurring between Day 1 and Day 30 of induction cycle)
- The incidence, intensity (according to the latest version of the CTCAE classification), duration, causality, severity and type of AA
详细描述
This protocol corresponds to a multicenter, phase II, open, non randomized, designed to determine the efficacy of clofarabine and low-dose cytarabine combination in AML patients older than or equal to 60 years.
The trial is divided into pre-treatment and treatment (cycle / s of induction and consolidation) periods.The induction cycle consist of clofarabine at 20 mg/m2/day intravenously for 5 consecutive days plus cytarabine subcutaneously at 20 mg/m2/day for 14 consecutive days. If patients do not achieve CR they will receive a second course of induction with the same pattern. Consolidation cycles consist of clofarabine intravenously at 15 mg/m2/day for 5 consecutive days plus cytarabine at 20 mg/m2/day subcutaneously for 7 consecutive days. Patients will receive a maximum of 12 cycles of clofarabine and LDAC. The monitoring phase of survival is made by clinical practice and will continue until all patients have either died or survived two years after the end of treatment visit.
There will be 75 patients older than or equal to 60 years. Patients will be evaluated over the following periods: Pre-treatment and treatment (induction and consolidation).
Pre-treatment phase: includes enrolment visit in which the patient completes the written informed consent to participate in the study.
There will be a selection of patients who have given their written informed consent to join the clinical trial. They must meet all the inclusion criteria and no exclusion.

- •Older than or equal to 70 years
- •Prior hematological disorder (AHD)
- •ECOG performance status 2
- •Unfavorable karyotype (ie, adverse) defined as any cytogenetic profile except the presence of any of the following:
- •t(8;21)(q22;q22) inv(16)(p13q22) or t(16;16)(p13;q22) t(15;17)(q22;q12) and variants
- •Provide written informed consent form.
- •Being able to comply with study procedures and follow-up evaluations.
- •Not to be fertile or willing to use a method of birth control during the study until the end of the last visit of the treatment.
- •Adequate renal and hepatic function as follows:
- •Total bilirubin <= 1,5 x upper of institutional normal limit (ULN) and
- •AST y ALT <=2,5 x ULN and
- •Serum creatinine <=1,0 mg/dL of serum creatinine <01,0 mg/dL, then, glomerular filtration rate (GFR) estimated must be >60 mL/min/1,73 m2 calculated from the equation of the Modification of Diet in Renal Disease (MDRD).
- •Adequate cardiac function determined by at least one of the following:
- •Left ventricular ejection fraction (LVEF) >=40% measured by echocardiography in Multiple Gated Acquisition (MUGA) scan or isotope angiography or

- •Pre-treatment with clofarabine.
- •Previous treatment for AML or a hematological disorder AHD (excluding palliative care, hydroxyurea, hematopoietic cytokines or lenalidomide [the latter only for a specific AHD]). Hematopoietic cytokines and lenalidomide should not have been administered within the 14 days preceding the first dose of study drug. If it is received any previous treatment for AML or AHD within the time limits allowed, drug-related toxicity, must have recovered to Grade 1 or less before the first dose of study drug.
- •Previous hematopoietic stem cell transplantation (HSCT).
- •External beam pelvic radiotherapy.
