title: Galiximab: a review.
abstract: BACKGROUND
  A significant number of patients relapse or do not respond to rituximab due to intrinsic or acquired resistance. Hence, mAbs targeting other cell surface antigens on B-cell lymphomas are being studied. CD80 is a glycoprotein expressed on Hodgkin's lymphoma, mature B-cell lymphomas and immunoeffector cells which may have T-regulatory, in addition to direct antitumor activity. CD80 serves as an attractive target in the continued development of mAbs against lymphoma.
  
  
  METHODS
  Preclinical studies with galiximab, an anti-CD80 primatized mAb, have been encouraging and have demonstrated antitumor activity against various B-cell lymphoma models, both as a single agent as well as in combination with rituximab. Data were reviewed from a PubMed literature search from 1975 to 2009 and also included a review of abstracts from published proceedings of annual meetings from the American Society of Hematology and International Conference of Malignant Lymphoma, Lugano.
  
  
  RESULTS
  Readers will gain a better understanding of mechanisms of action (both documented and proposed) of galiximab. An update of currently available clinical data will be presented.
  
  
  CONCLUSIONS
  Data from completed clinical trials are promising and galiximab is being studied in both upfront and relapsed settings with the potential of being incorporated into the future treatment of B-cell lymphoma.
