Retreatment with obinutuzumab: An addition to the therapeutic landscape of chronic lymphocytic leukemia.

Abstract

Obinutuzumab is used for the treatment of chronic lymphocytic leukemia. So far there are no data of using this for retreatment in patients who have received it previously. We introduced obinutuzumab for the retreatment in a chronic lymphocytic leukemia patient, who had first achieved partial remission with it and eventually relapsed over a course of 2.5 years. After retreatment with single-agent obinutuzumab, the patient achieved a partial remission again within one cycle and continues to maintain the response status. This case is a platform for considering obinutuzumab as a viable option for retreatment of chronic lymphocytic leukemia patients who have received it before, similar to the pattern of use for other anti-CD20 monoclonal antibodies in this disease, including rituximab.
