CD22 is expressed in almost all cases of B-cell acute lymphoblastic leukemia (B-ALL) and is therefore an attractive therapeutic target. In this issue of Blood , Zhao and colleagues identified genetic aberrations that impaired clinical response to the CD22-directed antibody-drug conjugate inotuzumab ozogamicin (InO) in adult patients with relapsed or refractory B-ALL. 1 Using extensive analysis of pre- and posttreatment patient samples, the authors identified genetic aberrations associated with primary and acquired resistance to InO.
