IA14 Induction in Young Acute Myeloid Leukemia

Study Overview
=================
Brief Summary
-----------------
Acute myeloid leukemia (AML) is a clinically and biologically heterogeneous disease characterized by the clonal expansion of undifferentiated myeloid precursors. Although induction chemotherapy with cytarabine and daunorubicin/Idarubicin, typically called 7+3, has not changed for several decades, the best dosage of anthracycline is still unknown. Several prospective trials have demonstrated that intense dosage of anthracycline improved complete remission (CR) and overall survival (OS). Idarubicin 12mg/m2 (IA12) has been shown to be equal to dose intense daunorubicin (90 mg/m2 ) for achieving CR. Dose-intense daunorubicin 90 mg/m2 (DA90) has been shown to improve CR compared to standard dose daunorubucin 45mg/m2 in newly diagnosed AML patients. In our previous study, CR rate of induction with daunorubicin 60 mg/m2/d (3 days) and cytarabine 200 mg/m2/d days 1-7 was about 67%. Benefit of intensification seems limited to the patients without adverse cytogenetics. Wheher ultra high dose idarubicin 14mg/m2 (IA14) could further improve CR rate, give patients with adverse cytogenetics a chance to do allo-stem cell transplantation? This phase 2, prospective, single-center study is designed to evaluate the efficacy and safety of induction with idarubicin 14mg/m2/d (3 days) and cytarabine 200 mg/m2/d days 1-7 in young newly diagnosed AML patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Complete remission (CR) rate | the rate of patient who get CR after induction therapy | On Day 21 (window Day 21 to Day 30), a bone marrow aspirate specimen will be collected for pathology. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Event-free survival (EFS) | EFS is defined as the duration from initiation of IA induction treatment to the date of a first event | Assessed up to 24 months. Event is defined as any of the following: 1)Refractory disease (or treatment failure) which is determined at the end of the Induction Phase; 2)Relapse after CR or CRi; 3)Death from any cause at any time during the study. |
