E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main of objective of the phase I part is to determine the optimum dose of Clofarabine (1-hour i.v. or push injection over 10 minutes) in combination with cytosine arabinoside and idarubicine to be recommended for the phase II trial.
The main objective of the randomized phase II part of the trial is to explore the antitumor activity of the above mentioned treatment combination using the recommended dose of Clofarabine (1-hour i.v. or push injection over 10 minutes) as defined in the phase I.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objective of the Phase I part is to determine activity expressed as CR/CRi rate following the induction (one or two cycles) and consolidation therapy, hematopoietic recovery (platelets and neutrophils) after induction and consolidation courses.
The secondary objectives of the Phase II part are: Safety/tolerability, activity expressed as CR/CRi rate following consolidation course, hematopoietic recovery (platelets and neutrophils) after induction and consolidation courses feasibility of blood CD34 harvesting after consolidation treatment. DFS and survival from CR/CRi, and overall survival will be evaluated as well.
The aim of the Phase II Part is also to investigate whether interaction between Clofarabine and cytosine arabinoside with respect to intracellular Ara-CTP and Clofarabine-TP levels takes place and whether a difference can be detected between the schedules with one-hour infusions or the push injections of Clofarabine. |

E.3 | Principal inclusion criteria |
• Age 18 – 60 years (including 60)
• AML according to the new WHO criteria i.e. percentage bone marrow (BM) blasts ≥ 20%, or MDS with ≥ 10% blast cells in the BM
• All AML FAB subtypes except M3
• All cytogenetic groups except:
- those with t(15;17)

• Primary and secondary AML (including AML after MDS)
• Previously untreated, except for ≤ 14 days of hydroxyurea
• WHO PS grade 0 – 2
• Adequate renal and hepatic function tests as indicated by the following laboratory values:
- serum creatinine ≤ 1.0 mg/dl(≤ 88.7micromol/L); if serum creatinine > 1.0 mg/dl (> 88.7micromol/L) then the glomerular filtration rate (GFR) must be > 60 ml/min/1.73 m2 as calculated by the Modification of Diet in Renal Disease equation where the predicted GFR (ml/min/1.73 m2 ) = 186x(serum creatinine in mg/dl)-1.154 x (age in years)-0.203 x (0.742 if patient is female) x (1.212 if patient is black).
NOTE: if serum creatinine is measured in micromol/L recalculate it in mg/dl according to the equation: 1 mg/dl=88.7micromol/L and used above mentioned formula
- Aspartate Transaminase(AST)/Alanine transaminase(ALT) ≤ 2.5 x ULN and alkaline phosphatase ≤ 2.5 x ULN .
• Potential fertile patients agree to use an effective barrier method of birth control during study treatment and for at least 3 months after end of study treatment.
• Before patient registration/randomization, written informed consent must be given according to ICH/EU GCP, and national/local regulations
• Patient can only be registered once in this Phase I/ Phase II trial |
|
E.4 | Principal exclusion criteria |
• Blast crisis of chronic myeloid leukemia or AML supervening a myeloproliferative disorder
• Central nervous system leukemia
• Concomitant malignant disease
• Active uncontrolled infection
• Concomitant severe uncontrolled cardiovascular disease i.e. symptomatic congestive heart failure or symptomatic ischemic heart disease (NYHA grade III-IV).
• Any psychological, familial, sociological, and geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
• Known HIV positivity
• Pregnancy (in case of doubt a pregnancy test is required) and breast feeding women
|
|
E.5 End points |
E.5.1 | Primary end point(s) |
• Phase I: determine the safety and tolerance of Clofarabine in combination with standard AML treatment during induction in order to determine the recommended dose (RD) for administration in phase II study.
• Phase II: determine the activity expressed as CR/CRi rate following the induction course (one or two cycles).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The final analysis will take place at approximately end of recruitment + 1 year. |
|
E.5.2 | Secondary end point(s) |
• Phase I: determine activity expressed as CR/CRi rate following the induction (one or two cycles) and consolidation therapy, hematopoietic recovery (platelets and neutrophils) after induction and consolidation courses.
• Phase II: Safety/tolerability, activity expressed as CR/CRi rate following consolidation course, hematopoietic recovery (platelets and neutrophils) after induction and consolidation courses feasibility of blood CD34 harvesting after consolidation treatment. DFS and survival from CR/CRi, and overall survival will be evaluated as well.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary endpoints will be analyzed at the same time as the primary endpoint analysis. |
