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.

Emerging drugs in cutaneous T cell lymphoma.

BACKGROUND: Mycosis fungoides (MF) represents the most common type of primary cutaneous T cell-lymphomas (CTCL), which are characterized by a clonally proliferation of malignant CD4+ lymphocytes in the skin. OBJECTIVE: Skin-directed treatment regimens, like phototherapy and corticosteroids, are commonly used in early stages; systemic treatments and chemotherapies are used in advanced stages. Because conventional treatments usually end in a transient remission without curative results, there is a high need for new therapeutic strategies with acceptable side effects. METHODS: Literature and reference research was done by using the data bank PubMed, and updates of ongoing studies were taken out of ASCO and ASH annual meeting abstracts. RESULTS/CONCLUSIONS: This article gives an overview of the various medications in current use, with emphasis on emerging drugs with novel therapeutic targets.
