Summary
Brief summary (as posted)
Blinatumomab is a new active bispecific monoclonal antibody for treatment of lymphoid malignancies, including ALL (acute Lymphoblastic Leukemia ) whose activity for remission induction needs to be explored in combination with standardized treatment in order to improve outcome of this disease which is still lethal in most adult patients. Ultimate proof of efficacy resides in an increase of reaching MRD ( minimal residual disease) negativity, prolongation of that response, and long-term survival. Since hematological response rate in adult ALL is high already and defining long-term survival in a large clinical trial takes many years, this trial aims to improve the strength of the MRD response as defined by achieving complete MRD negative response (ie, \< 10\^-4) after the first consolidation phase including blinatumomab. This MRD response will be assessed by Real-Time Quantitative Polymerase Chain Reaction (RQ-PCR) analysis of patient-specific Ig/TCR (T-cell receptor ) gene rearrangements. When MRD data are missing, MRD positivity will be assumed. Although younger (up to 40 years of age) patients are treated more intensively than older patients (older than 40 years of age), the investigational questions concerning blinatumomab can be examined in both subgroups as both younger and older patients receive the same type of chemotherapy courses with dose adjustments for chemotherapeutic agents only for patients above 60 years of age.

- EXPERIMENTAL
- label
- Blinatumomab
- description
- After a 5-day steroid prephase patients will receive two weeks continuous infusion of blinatumomab. Then the first remission-induction course will be given after one week interruption. Subsequent therapy with 4 cycles of chemotherapy and two 4-week courses of blinatumomab will follow, and subsequently depending on risk group, eligibility and a suitable donor either allogeneic stem cell transplantation or 2 year maintenance treatment.

Primary outcomes (1)
- measure
- The proportion of patients that achieve MRD ( minimal residual disease) negative response, measured by Polymerase Chain Reaction (PCR), after the first blinatumomab consolidation course. MRD negative response is defined as MRD <10-4
- timeFrame
- 1 year after closure of study
Secondary outcomes (7)
- measure
- Complete and molecular response rate following induction and after blinatumomab consolidation ll by the addition of i.v. blinatumomab to standard prophase, consolidation and intensification therapy
