Multicenter Clinical Trial for Adult Ph-negative ALL. Non-intensive But Non-iterruptive Treatment
|ClinicalTrials.gov Identifier: NCT01193933|
Recruitment Status : Active, not recruiting
First Posted : September 2, 2010
Last Update Posted : March 7, 2018
- 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
- feasibility for adults of "no interruptions" protocol with 8 weeks induction and 14 weeks consolidation followed by 2-years maintenance.
- tolerability and efficacy in adults of the prolonged L-asparaginase application (total proposed dose 560.000 IU)
- 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|
- 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.
- "no interruptions" induction was performed in 48% of patients.
- In 19% of patients the L-asparaginase therapy was stopped due to toxicity.
- Autologous stem cell transplantation was done in 20% of T-cell ALL patients.

|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.|
|Study Start Date :||November 2008|
|Actual Primary Completion Date :||December 2016|
|Estimated Study Completion Date :||December 2021|
Procedure: autologous HSCT
- 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
- 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
