Mogamulizumab, sold under the brand name Poteligeo, is a medication used to treat mycosis fungoides and Sézary disease.[1][2] It is used when other treatments are not effective.[1] It is given by gradual injection into a vein.[1]

Common side effects include rash, pneumonia, fever, and cellulitis.[2] Other side effects may include Stevens-Johnson syndrome, sepsis, pneumonitis, myocarditis, and polymyositis.[1] Use in pregnancy may harm the baby.[1] It is a monoclonal antibody that binds to CC chemokine receptor 4 (CCR4) found on white blood cells.[2]

Mogamulizumab was approved for medical use in the United States and Europe in 2018.[1][2] In the United Kingdom 4 mg cost the NHS about £1,300 as of 2021.[5] This amount in the United States costs about 4,200 USD.[6]

Medical uses

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).[7] The latter approval was based on study with 28 subjects.[8]


It is given at a dose of 1 mg/kg once a week for 4 weeks than once every two weeks.[5]

Mechanism of action

Mogamulizumab’s main mechanism of action[9]

In terms of the mode of action of Mogamulizumad we find that it targets CCR4 that is found on surface of T-cell lymphocytes(some T cells become cancerous). Mogamulizumab attracts the immune system to attack the cancerous T cells. Additionally, it blocks the signals that CCR4 sends inside cells, which are signals that help the T cells to survive and multiply.[9]


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.[7] [10] This is thought to enhance its antibody-dependent cell-mediated cytotoxicity.[11] It was first tested in humans in 2007.[10]

Kyowa licensed rights for use outside of cancer to Amgen in 2008, for $100 million up front and $420 million in biodollars.[12] Amgen ran a Phase I study to explore its use in asthma.[13] Amgen terminated the agreement in 2014.[12]

As of 2014, there were reports that mogamulizimab can cause serious skin rashes and some cases of Stevens–Johnson syndrome.[13]

In 2017, the US FDA granted it a priority review for CTCL.[14] Full approval was granted in August 2018.[15] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[16]


Mogamulizumab is being explored as a treatment for HTLV-1–Associated Myelopathy. An early Phase 1-2a study showed decreased in proviral loads, as well as inflammatory markers in the CSF. 79% of the patients showed reduction in spasticity and 32% showed decrease in motor disability.[17]
