Brief summary

EFS defined as the time from diagnosis to resistance to induction (i.e. no complete remission at the end of induction) , relapse, death from any cause or second malignancy (whichever occurs first), or time to last follow-up (censored) for patients without events.

Detailed description

OS is defined as the time from the date of diagnosis to death from any cause. Patients who are alive will be censored at the date of last follow up. OS will be estimated for the entire study cohort and according to risk group., The endpoints for analysis by risk group will be EFS, cumulative incidence (or percentage) of resistance to induction (no complete remission at the end of induction) , cumulative incidence of relapse (CIR), death in complete remission (CR) and second malignancy., Outcome for the entire study cohort and according to risk group will be evaluated in terms of the protocol specific definition of EFS follows: the time from diagnosis to, resistance to proto-col, relapse, death from any cause or second malignancy (whichever occurs first), or time to last follow-up for patients without events. Cumulative incidence (or percentage) of resistance, CIR, death in CR and second malignancy will also be estimated., MRD response as defined in the protocol and frequencies of MRD levels., Proportion of CD19 negative relapses in the entire study cohort and according to risk group., Proportion of myeloid lineage switches in the entire study cohort and according to risk group., Proportion of grade ≥3 adverse event (AEs) during the blinatumomab course(s). Proportion of adverse events of special interest (AESIs) and serious adverse events (SAEs) in all protocol phases., Proportion of grade ≥2 cardiac disorders (See AESI Table in protocol) at 2 and 5 years after diagnosis, OS after first relapse, defined as the time from first relapse to death from any cause, in the entire study cohort and according to risk group.
