Mogamulizumab (trade name Poteligeo)[1] is a humanized, afucosylated monoclonal antibody targeting CC chemokine receptor 4 (CCR4).[2] The US FDA approved it in August 2018 for treatment of relapsed or refractory mycosis fungoides and Sézary disease.[3] It was approved in Japan in 2012 for the treatment of relapsed or refractory CCR4+ adult T-cell leukemia/lymphoma (ATCLL) and in 2014 for relapsed or refractory CCR4+ cutaneous T cell lymphoma (CTCL).[2] The latter approval was based on study with 28 subjects.[4]

The precursor to mogamulizumab was a mouse anti-human CCR4 IgG1 mAb (KM2160), that was made in 1996 in a collaboration between Kouji Matsushima of University of Tokyo and Kyowa Hakko Kirin. Kyowa humanized it, and expressed the humanized gene in a CHO cell line in which FUT8 had been knocked out, which produced antibodies with no fucose in the Fc region.[2][5] This is thought to enhance its antibody-dependent cell-mediated cytotoxicity.[6] It was first tested in humans in 2007.[5]

Kyowa licensed rights for use outside of cancer to Amgen in 2008 for $100 million up front and $420 million in biodollars.[7] Amgen ran a Phase I study to explore its use in asthma.[8] Amgen terminated the agreement in 2014.[7]

As of 2014 there were reports that mogamulizimab can cause serious skin rashes and some cases of Steven-Johnson syndrome.[8]

Late in 2017 the US FDA granted it a priority review for CTCL.[9] Full approval was granted in August 2018.[10]
