Brief Summary:
  1. evaluation of blast clearance in b/m after 7 days of prednisolone prephase and the efficacy of its substitution by dexamethasone if blast count is 25% and more
  2. feasibility for adults of "no interruptions" protocol with 8 weeks induction and 14 weeks consolidation followed by 2-years maintenance.
  3. tolerability and efficacy in adults of the prolonged L-asparaginase application (total proposed dose 560.000 IU)
  4. feasibility and efficacy of autologous stem cell transplantation for T-cell ALL

Condition or disease Intervention/treatment Phase
Ph-negative Adult Acute Lymphoblastic Leukemia Procedure: autologous HSCT Not Applicable

Detailed Description:
  1. The blast count in b/m after 7 days of prednisolone >25% was shown in 64% of patients. The substitution of prednisolone by dexamethasone did not influence survival.
  2. "no interruptions" induction was performed in 48% of patients.
  3. In 19% of patients the L-asparaginase therapy was stopped due to toxicity.
  4. Autologous stem cell transplantation was done in 20% of T-cell ALL patients.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Proportion of adult ALL patients who tolerated the non-interrupted treatment [ Time Frame: 3 years ]
    Number of patients who finished the protocol without any deviation, who were off the protocol due to toxicity, in whom the treatment schedule was modified and respectively the antileukemia efficacy in those subgroups


Secondary Outcome Measures :
  1. Toxicity of prolonged L-asparaginase in adult patients [ Time Frame: 3 years ]
    Number of patients who tolerated the scheduled L-asparaginase by dose and time sequence, proportion of patients shifted to PEG-asparaginase, in whom L-asparaginase was stopped and, respectively, the survival without leukemia of those patients
