Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the activity of a combination approach based on dasatinib and blinatumomab in obtaining a minimal residual disease MRD negativity (complete molecular response: CMR, e.g. BCR-ABL1/ABL1=0) in adult Ph+ ALL.;Secondary Objective: 1) The feasibility of a chemo-free approach, based on Dasatinib and Blinatumomab, in adult Ph+ ALL patients =18 years, with no upper age limit 2) CMR achievement after induction with Dasatinib 3) Capability of Blinatumomab to reduce the MRD levels (an extension of the primary objective) 4) CMR duration 5) Disease-free survival (DFS) 6) Overall survival (OS) 7) Cumulative incidence of relapse (CIR) 8) Safety profile 9) CMR achievement, duration of CMR, OS and DFS according to the clinical, biological and molecular characteristics: clinical and biological assessment at baseline, type of fusion protein (p190 vs p210) and presence of additional genomic lesions identified by SNP arrays.;Primary end point(s): The rate of patients who achieve MRD negativity (CMR) upon treatment, in particular: the rate of patients in CMR after 2 cycles of Blinatumomab.;Timepoint(s) of evaluation of this end point: Interim analysis will be performed after the first stage (29 evaluable patients) and at the end of the study. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1) Feasibility, calculated on the rate of patients completing the 2 cycles of Blinatumomab treatment and alive in first CHR from day +85 at 12 months 2)Rate of patients in CMR at day +22, +45, +57 and +85 3) CMR duration 4) DFS 5) OS 6) CIR 7) Safety profile in terms of incidence of grade >3 CTC-NCI side effects and toxicities. 8) Role of clinical and biological assessment at baseline, type of fusion protein (p190 vs p210) and presence of additional genomic lesions identified by SNP arrays on CMR achievement, duration of CMR, OS and DFS.;Timepoint(s) of evaluation of this end point: At the end of the study | — |
