Information provided by (Responsible Party):
Elena N.Parovichnikova, National Research Center for Hematology, Russia
  Purpose
  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 Intervention
Ph-negative Adult Acute Lymphoblastic Leukemia Drug: L-asparaginase

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Multicenter Clinical Trial for Adult Ph-negative ALL. Evaluation of the Impact of the Prolonged L-asparaginase Therapy During Continuous Treatment With Modification of Cytostatic Drugs Doses Depending on Myelosuppression Severity.

Further study details as provided by Elena N.Parovichnikova, National Research Center for Hematology, Russia:

Primary Outcome Measures:
  • 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:
  • 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


Estimated Enrollment: 230
Study Start Date: November 2008
Estimated Study Completion Date: December 2014
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: L-asparaginase
    prolonged L-asparaginase application at 10.000 IU weekly in induction, once in two weeks in 14 weeks consolidation, twice a month in maintenance (total proposed dose 560.000 IU)
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.
