Blinatumomab is a bispecific T-cell engager (BiTE) antibody construct targeting CD3 and CD19, resulting in T-cell-mediated lysis of malignant B cells. CD19 downexpression is shown to be one of the possible mechanisms of tumor cells adaptation and subsequent escape from treatment. The aim of the present study was to evaluate changes of CD19 expression on residual tumor cells in children with BCP-ALL treated with blinatumomab. 39 patients with relapsed/refractory BCP-ALL who completed at least one course of blinatumomab, were studied. MRD monitoring was performed by 8-color flow cytometry. In those children, who didn’t respond and/or developed subsequent relapse, CD19 downexpression seems to be one of the significant pathways for tumor escape from blinatumomab – 50% of relapses were CD19-negative, and in 26.3% of all relapsed/resistant cases CD19-negative blasts were detected at least on MRD level. Rather frequent loss of CD19 could be a serious obstacle for flow cytometric MRD monitoring, but application of expanded antibodies panel and use of 10–12-color investigation allows residual blasts detection in nearly all cases.
