Efficacy and Toxicity of Increasing Doses of Idarubicin, Cytarabine and G-CSF in Acute Myeloid Leukemia
While several studies have been reported with increasing doses of daunorubicin in the first line treatment of Acute Myeloid Leukemia (AML), there is no similar experience with idarubicin as initial treatment of AML.
As idarubicin is the most common treatment used for AML, it is needed to find the optimal dose for the combination of idarubicin, cytarabine and G_CSF, to explore if this combination improves the outcomes of current treatments for AML.
The aim of this dose-finding study is to find the optimal dose for the combination of idarubicin, cytarabine and G-CSF that could improve the response rate, reduce relapse and improve survival of patients with primary acute myeloid leukemia. This could be a significant advance in a field where treatment outcomes have stabilized in the last 15 years. This study will be the basis for further prospective, randomized, multicenter trial comparing idarubicin maximum tolerated dose, compared to standard treatment with idarubicin and cytarabine, including raising both arms in G-CSF. The dose of 12 mg/m2 will be administered as control arm in this future randomized study, which will investigate the benefit of enhanced dose identified as optimal in this phase II pilot study.

- Rate of complete remissions (CR) [ Time Frame: From 28 up to 56 days after first induction ]Identify the highest dose of idarubicin in combination with cytarabine and G-CSF that produces a CR rate equal to or greater than 65% with tolerable toxicity.
- Rate of patients with adverse events as a measure of safety and tolerability [ Time Frame: Weekly during treatment, and on months 3 and 6 after complete response ]Hematologic toxicity Gastrointestinal and liver toxicity Cardiac Toxicity Fever and infection Pulmonary complications Duration of hospitalization Mortality and causes of death induction.
- Duration of hospitalization [ Time Frame: From the inclusion until 9 months after inclusion. ]Number of days in which the patient is hospitalized.
- Mortality (as rate) related to study treatment [ Time Frame: Weekly during treatment, 3 months after complete remission, 6 months after complete remission and 9 months after complete remission ]Causes of death, mortality related treatment, mortality in induction.
- Relapse at 6 months [ Time Frame: 6 months from complete remission, expected to be within 9 months from inclusion. ]Rate of patients that have relapsed within 6 months after complete remission.
- Survival at 9 months from diagnosis [ Time Frame: 9 months after diagnoses ]Rate of patients alive at 9 months after diagnosis.
