POTELIGEO

MOGAMULIZUMAB-KPKC Chemokine Receptor Type 4 Interactions
Approved 2018-08-08

POTELIGEO (mogamulizumab-kpkc) is a monoclonal antibody indicated for the treatment of adult patients with mycosis fungoides (MF) or Sézary syndrome (SS). It is specifically used for cases that are relapsed or refractory following at least one prior systemic therapy. This therapy provides a targeted treatment option for patients with these specific forms of cutaneous T-cell lymphoma who have not responded to previous systemic treatments.

How POTELIGEO Works

Mogamulizumab-kpkc is a humanized monoclonal antibody that binds to CC chemokine receptor type 4 (CCR4), a protein involved in the trafficking of lymphocytes to various organs. This receptor is expressed on the surface of certain T-cell malignancies, as well as regulatory T-cells and specific Th2 T-cells. By binding to CCR4, the drug targets these cells for antibody-dependent cellular cytotoxicity, which results in the depletion of the malignant target cells.
