Primary Outcome Measures:
  • Toxicity according to National Cancer Institute/Common Toxicity Criteria (NCI/CTC), especially the rate of severe infections and the death rate [ Time Frame: continuous ]
  • Rate of complete remission

Secondary Outcome Measures:
  • Remission duration
  • Overall survival
  • Influence of cytogenetic aberrations on remission rate, duration of remission and overall survival
  • Course of CD3/CD4+ subpopulation after therapy

Estimated Enrollment: 50
Study Start Date: November 2004
Estimated Study Completion Date: March 2011
Estimated Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: cladribine
    2-chlorodeoxyadenosine, 2-CdA
Detailed Description:

Considerable progress has been made in the induction therapy of acute myeloid leukemia (AML); however, current therapeutic results are still unsatisfactory in those with relapsed disease. The purine nucleoside analogue cladribine (2-chlorodeoxyadenosine, 2-CdA) has been shown to be a safe and active agent in acute myeloid leukemia. Synergistic interaction between cladribine and cytarabine has been demonstrated in preclinical and clinical studies.

The current multicenter phase II study was initiated to evaluate the efficacy and toxicity of cladribine, high-dose cytarabine, and idarubicin in the treatment of patients with relapsed AML. Adult patients of all age groups can be enrolled in the trial, but elderly patients will be treated with a less dose-intensive regimen.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with relapsed AML with a remission duration of at least 6 months after first complete remission (CR) or of at least 3 months after second (or higher) CR

  • Cardiac insufficiency grade III or IV New York Heart Association (NYHA)
  • Severe renal insufficiency with a clearance of < 30 ml/min (if not due to AML)
  • Severe hepatic insufficiency with bilirubin > 3 mg/dl or AST > 200 U/l (if not due to AML)
  • Other severe organ impairment grade III or IV World Health Organization (WHO) (if not due to AML or, in the opinion of the investigator, may not interfere with the procedures in the study)
  • HIV infection
  • Intolerance to study drugs
  • Pregnant or breast-feeding women
  • Any other malignant disease which will probably affect the course of AML
