| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
To establish the recommended dose of clofarabine in combination with cytarabine and liposomal daunorubicin (DaunoXome®) in children with relapsed/refractory AML.  
 Note: dosages of cytarabine and liposomal daunorubicin should be comparable to those used in the current Relapsed AML 2001/01 study (i.e. in the context of the FLAG/liposomal daunorubicin regimen). | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
- To determine the safety and tolerability of this combination - To determine (preliminary) efficacy in terms of the hematological remission rate in these patients - To describe the durability of response, including the number of patients that undergo stem-cell transplant after re-induction with this regimen - To describe the pharmacokinetics of clofarabine in combination with cytarabine and liposomal daunorubicin - To preliminary assess the CSF blast disappearance, and the CSF-levels of clofarabine

| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
• 2nd relapse of AML • refractory AML in 1st relapse (defined as  ≥ 20% blasts in the bone marrow after the 1st course of re-induction therapy according to the AML 2001/01 protocol) • 1st early relapse (relapse within one year from initial diagnosis) of AML (only when the Relapsed AML 2001/01 study is closed) • ≤ 18 years old at initial diagnosis • Lansky play score > 60; or Karnofsky performance status > 60 • Life expectancy  6 weeks • Calculated creatinine clearance ≥ 90 ml/min/1.73m2 as calculated by the Schwartz formula for estimated glomerular filtration rate (GFR) where GFR (ml/min/1.73 m2) = k*Height (cm)/serum creatinine (mg/dl). k is a proportionality constant which varies with age and is a function of urinary creatinine excretion per unit of body size; 0.45 up to 12 months of age; 0.55 children and adolescent girls; and 0.70 adolescent boys. • Liver function:          Serum bilirubin ≤1.5 × upper limit of normal (ULN)          Aspartate transaminase (AST)/alanine transaminase (ALT) £2.5 × ULN          Alkaline phosphatase £ 2.5 × ULN  • Able to comply with scheduled follow-up and with management of toxicity. • For female patients with childbearing potential, a negative test for pregnancy is to be considered before entry on study • Male and female patients must use an effective contraceptive method during the study and for a minimum of 6 months after study treatment. • Written informed consent from patients or from parents or legal guardians for minor patients, according to local law and regulations

 | 
| E.4 | Principal exclusion criteria | 
• Isolated extramedullary relapse, including isolated CNS-relapse • Symptomatic CNS leukemia in case of combined relapse • Relapsed/refractory acute promyelocytic leukemia  (APL) • Relapsed/refractory myeloid leukemia of Down Syndrome (ML DS) • Other serious illnesses or medical conditions  • Current uncontrolled infection • Evidence of cardiac dysfunction (shortening fraction below 28%) • Pregnant or lactating patients Prior or current history:  • Use of any anticancer therapy within 2 weeks before study entry. The patient must have recovered from all acute toxicities from any previous therapy (note: hematological toxicities do not need to be considered since the patient has overt leukemia). • History of prior veno-occlusive disease (VOD) • Hypersensitivity to cytarabine, clofarabine or liposomal daunorubicin

 | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| To identify the recommended dose of the combination of clofarabine, cytarabien an dliposomal daunorubicin in relapsed/refractory AML, hence to identify dose-limiting toxicities and the MTD. |
