Chimeric Use Statement:This chimeric mouse antibody was made using the variable domain sequences of the original Human IgG1 format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement:This antibody is specific for human CCR4, a chemokine receptor that is preferentially expressed by Th2 and regulatory T (Treg) cells. CCR4 is also detected on basophils, platelets, monocytes and brain microvascular and coronary artery endothelial cells.
Application Notes:The clinically used format of this antibody (which underwent additional de-fucosylation to increase antibody-dependent cellular cytotoxicity (ADCC)), has significant clinical activity in heavily pretreated patients with mycosis fungoides and Sézary syndrome, and is associated with an overall response rate of 36.8% and a median duration of response of 10.4 months (Duvic et al, 2014). It was shown to CCR4-expressing cells by antibody-dependent, cell-mediated cytotoxicity (ADCC). Therapeutically, this results in a dual mechanism of action; in addition to directly targeting malignant T cells over-expressing CCR4, this antibody also depletes T reg cells, an important therapeutic target in human cancers. This antibody is well-tolerated, and administration does not appear to trigger clinically significant autoimmune complications in phase 1/2 trials (Duvic et al, 2014). This antibody has been approved in Japan for the treatment of relapsed or refractory adult T-cell leukemia/lymphoma, and is in clinical trials for solid cancers. For the avoidance of doubt - the material produced by Absolute Antibody has not been de-fucosylated.
