Zanolimumab, a human monoclonal antibody targeting CD4 in the treatment of mycosis fungoides and Sézary syndrome.

Background: The most common type of primary cutaneous T cell-lymphomas (CTCLs), which are characterised by a clonal proliferation of malignant skin-homing CD4(+) lymphocytes, is mycosis fungoides (MF) and its rare leukaemic variant Sézary syndrome (SS).
Objective: Zanolimumab is a high affinity human monoclonal IgG1k antibody, targeting the CD4-molecule. It exhibits cytotoxic and antiproliferative effects and has previously shown efficacy in CTCLs.
Methods: Literature and reference research was done by using Pubmed and updates of ongoing studies were taken from American Society of Clinical Oncology (ASCO) and American Society of Hematology (ASH )annual meeting abstracts.
Results: This article gives an overview about efficacy, tolerability and safety as well as chemistry, pharmacodynamics and pharmacokinetics of zanolimumab in the treatment of CTCLs.
