Colitis mimicking graft-versus-host disease during treatment with the anti-CCR4 monoclonal antibody, mogamulizumab

Abstract: A 57-year-old male with acute-type adult T cell leukemia-lymphoma (ATL) developed persistent watery, non-bloody diarrhea at a volume of 2-3 L/day following the administration of the anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, mogamulizumab. An extensive examination revealed the absence of any pathogenic bacteria or parasites in his stool. Biopsied specimens from the colonic mucosa contained many small nests of apoptotic bodies in the colonic glands, which mimicked acute-colonic graft-versus-host d… Show more

“…12 There is a report of a patient in whom a severe, treatment-refractory colitis developed during treatment with mogamulizumab, which further highlights the impact of depletion of Treg cells and loss of tolerance of cutaneous and enteric commensal organisms. 13 The MAR noted in our patient had a primarily granulomatous histologic pattern, with a clinical presentation resembling Malassezia-driven head and neck dermatitis, as observed in patients with severe atopic dermatitis. Itraconazole and azole antifungals were effective treatments in more than two thirds of adult patients with head and neck dermatitis on atopic skin background 14 and also were found to be effective in our patient.…”

“…In ulcerative colitis, adoptively transferred CCR4-deficient Tregs fail to inhibit T cell proliferation due to delayed migration 40 . In turn, treatment of adult T-cell lymphoma with the CCR4 antibody mogamulizumab can cause colitis mimicking GvHD, which is suspected to be due to Treg depletion 29 . Therefore, the protective capacity of Tregs should be considered when targeting CCR4 in GvHD.…”

“…Thus, strategies to improve the outcomes of allo-HSCT preceded by MOG treatment are needed. Because MOG is a potent anti-ATLL agent and will be used to treat other T cell malignancies, future studies should be aimed at developing new treatment protocols integrating MOG at a suitable dose and with proper timing of administration to minimize GVHD and enhance the GvATLL effect [44][45][46][47].…”
