Mogamulizumab: 2 birds, 1 stone

Abstract

In this issue of Blood, Duvic et al demonstrate that mogamulizumab, a humanized monoclonal antibody targeting the chemokine receptor CCR4, is well tolerated and has significant clinical activity (overall response rate 36.8%, median duration of response 10.4 months) in heavily pretreated patients with mycosis fungoides (MF) and Sézary syndrome (SS).
