title: Inotuzumab ozogamicin in B-cell acute lymphoblastic leukemias and non-Hodgkin's lymphomas.
abstract: BACKGROUND
  The expression profile of the CD22 antigen and its role in B-cell function make it an important target in B-cell leukemias and lymphomas. Inotuzumab ozogamicin (IO), a humanized monoclonal antibody targeting CD22, is one of the most promising monoclonal antibodies for the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (ALL).
  
  
  METHODS
  This article reviews the current literature of IO in adult leukemias and lymphomas.
  
  
  CONCLUSIONS
  Single-agent IO has demonstrated activity in patients with relapsed B-cell ALL and non-Hodgkin lymphoma (NHL). It has also demonstrated favorable early results when combined with chemotherapy in older patients with ALL. There is potential for IO to be combined with other targeted therapies under development for these diseases; data are still early and further studies of IO are warranted. While the pivotal randomized study of IO for relapsed NHL versus physician's choice did not show a statistically significant advantage in response rate, the results of the pivotal study in ALL are not yet available.
