Blinatumomab for Treatment of R/R or MRD-positive CD19-Positive MPAL

Blinatumomab (BLINCYTO , AMG 103, formerly also known as MT103 or bscCD19xCD3) is a novel single chain antibody construct in the class of the bispecific T-cell engager (BiTE®). Blinatumomab directs CD-3 positive effector memory T cells to CD19-positive target cells (Hoffmann et al, 2005; Dreier et al, 2002). The targeted CD19 antigen is constitutively expressed on normal B cells throughout a person's lifetime (Smet et al, 2011) and is highly conserved in B-cell malignancies (Tedder, 2009; Wang et al, 2012).
