Project description:Aim: This study assessed the cost-utility of mogamulizumab, a novel monoclonal antibody, versus established clinical management (ECM) in UK patients in previously treated advanced mycosis fungoides (MF)/Sézary syndrome (SS). Materials & methods: Lifetime partitioned survival model based on overall survival, next treatment-free survival and the use of allogeneic stem cell transplant was developed. Inputs were from the pivotal MAVORIC trial, real-world evidence and published literature. Extensive sensitivity analyses were conducted. Results: Discounted incremental quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio were 3.08, £86,998 and £28,233. Results were most sensitive to the survival extrapolations, utilities and costs after loss of disease control. Conclusion: Mogamulizumab is a cost-effective alternative to ECM in UK patients with previously treated advanced MF/SS.

Project description:Granulomatous Mycosis Fungoides (GMF) is a rare form of mycosis fungoides (MF) characterized by a granulomatous infiltrate associated with the neoplastic lymphoid population and is considered to have a worse prognosis compared with regular MF. The upregulation of the T helper (Th) axis, especially Th17, plays an important role in the pathogenesis of several inflammatory/infectious granulomatous cutaneous diseases, but its role in GMF is still not elucidated to date. In this study, we evaluated the immunohistochemical expression of Th1 (Tbet), Th2 (GATA-3), Th17 (RORγT), T regulatory (Foxp3), and immune checkpoint (IC) (PD-1 and PD-L1) markers in a cohort of patients with GMF and MF with large cell transformation (MFLCT). Skin biopsies from 49 patients (28 GMF and 21 MFLCT) were studied. Patients with GMF were associated with early clinical stage (p = 0.036) and lower levels of lactate dehydrogenase (p = 0.042). An increased percentage of cells positive for Tbet (p = 0.017), RORγT (p = 0.001), and PD-L1 (p = 0.011) was also observed among the GMF specimens, while a stronger PD-1 intensity was detected in cases of MFLCT. In this cohort, LCT, RORγT < 10%, Foxp3 < 10%, age, and advanced stage were associated with worse overall survival (OS) in univariate analysis. GMF demonstrated Th1 (cellular response) and Th17 (autoimmunity) phenotype, seen in early MF and granulomatous processes, respectively, which may be related to the histopathological appearance and biological behavior of GMF. Further studies involving larger series of cases and more sensitive techniques are warranted.

Project description:BackgroundCutaneous T-cell lymphomas (CTCL) are rare types of non-Hodgkin lymphoma, which present in skin. Mycosis fungoides (MF) and Sézary syndrome (SS) are subtypes which make up two-thirds of all CTCL cases. The phase 3 MAVORIC study (NCT01728805) compared mogamulizumab to vorinostat in MF and SS patients, with post hoc data showing a trend for higher efficacy in mogamulizumab-treated patients as baseline blood tumour burden increases.ObjectivesThe aim of this study was to use updated post hoc analyses in order to examine the efficacy of mogamulizumab and vorinostat in MF patients when stratified by baseline blood involvement and to determine what factors affect time-to-global and time-to-skin response to inform clinical follow-up.MethodsPost hoc analyses were carried out using data from MAVORIC. Overall response rate (ORR), progression-free survival (PFS) and time-to-next-treatment (TTNT) data were used to assess efficacy in patients with MF. Time-to-global response (TTR) was examined by disease subtype, by blood involvement in MF patients, and time-to-skin response was examined by blood involvement in MF patients.ResultsNumerically superior results were seen for ORR, PFS and TTNT in mogamulizumab-treated patients with MF compared with vorinostat, with a trend for outcomes improving with increasing baseline blood class. Statistically significant results for mogamulizumab compared with vorinostat were seen for MF B1 pts for PFS (8.43 vs. 2.83 months, p = 0.003) and TTNT (11.9 vs. 3.13 months, p = 0.002), and for MF B2 pts for ORR (46.2 vs. 9.1 months, p = 0.033).ConclusionsIn mogamulizumab-treated MF patients, ORR and PFS were seen to improve with increasing blood involvement, which led to improved TTNT. TTR was more predictable for mogamulizumab-treated MF patients with blood involvement, and skin response may take longer than previously reported in some patients.

Project description:This report describes the cases of two patients with mycosis fungoides and Sézary syndrome (MF/SS) who achieved clinical benefit with mogamulizumab combination therapies. Case 1 is a 56-year-old male with stage IIIB (T4NxM0B1) MF, which later progressed into SS, with ongoing skin symptoms (erythema, lichenified skin, and pruritis) and axillary and inguinal lymphadenomegaly. Skin-directed and systemic therapies failed to achieve a long-lasting response in this patient. Mogamulizumab (1 mg/kg once weekly for 4 weeks; once every 2 weeks thereafter) yielded temporary improvement in skin symptoms, but progression in the skin was confirmed after ~2 months. Subsequently, the combination of mogamulizumab with psoralen plus ultraviolet light A (PUVA) yielded a partial response; however, PUVA was discontinued due to phototoxicity and mogamulizumab was continued as monotherapy. At the latest evaluation, clinical improvement in the skin and reduced lymphadenomegaly were evident with ongoing mogamulizumab monotherapy; the patient is awaiting allogeneic hematopoietic stem cell transplantation. Case 2 is an 80-year-old male with stage IIIB (T4NxM0B1) granulomatous variant MF who presented with diffuse erythema with desquamation, ectropion, and inguinal lymphadenopathy. Treatment with oral prednisone and bexarotene failed to achieve adequate, long-lasting responses. Mogamulizumab (1 mg/kg once weekly for 4 weeks; once every 2 weeks thereafter) monotherapy yielded an initial improvement, characterized by less intense erythema, but the improvement was not sustained. Mogamulizumab was supplemented with oral prednisone and then PUVA; this combination resulted in improvement in the skin. PUVA was stopped due to unavailability, and methotrexate (10 mg once weekly) was initiated alongside continued mogamulizumab; this led to improvement in erythema. The patient continued mogamulizumab plus methotrexate with improving clinical status, prior to their death, which was deemed to be unlikely to be related to treatment. Our experience suggests that, in principle, mogamulizumab can be used in combination with other therapies; however, further research is needed.

Project description:Mycosis fungoides (MF) is the most common and best studied of cutaneous T-cell lymphoma (CTCL). Three clinical cutaneous stages have been described (patch, plaque and tumor) as the disease progress developing also the disease lymph node, peripheral blood or systemic involvement in late stages. Clinical and pathologic diagnosis of early MF stages (patch and plaque) is difficult as its morphologic similarity to inflammatory dermatoses and low proportion of tumoral cells.

Project description:Mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma, is characterized by patches, plaques, and, in advanced stages, tumors and erythroderma. Early-stage MF may progress to advanced-stage disease in up to one-third of patients, conferring a worse prognosis and typically requiring systemic treatment for extracutaneous involvement. The most frequently reported signs and symptoms are pain, pruritus, scaling, and skin redness, with pruritus, the most bothersome symptom, exerting a profound impact on patients' health-related quality of life (HRQoL). These dermatologic signs and symptoms can overlap with those of other benign inflammatory dermatoses, such as eczema and psoriasis, and therefore, diagnostic delay is common in patients with MF. Moreover, identifying patients with features adversely affecting prognosis (e.g. large-cell transformation or folliculotropic variant) is a significant challenge. We report the case of a 75-year-old female patient who was misdiagnosed with eczema and then pityriasis rubra pilaris and consequently did not receive treatment for MF for 4 years. The patient was eventually correctly diagnosed with MF [stage IIIB (T4 N1 M0 B1)] in September 2018. The patient received several systemic treatments; however, she did not respond to or tolerate the treatments. Due to lack of treatment response, in July 2021, she was initiated on mogamulizumab, an anti-CC chemokine receptor 4 antibody with demonstrated effectiveness and licensed approval for adults with MF/Sézary syndrome who have received one or more prior systemic therapies. Treatment rapidly led to a complete response in blood after 1 week and in skin after 4 months. Mogamulizumab was well tolerated by the patient, who also reported a significant improvement in her HRQoL. After 1 year in complete response, mogamulizumab was discontinued. This case highlights the need for accurate and early diagnosis of MF to initiate disease-specific treatment and the importance of considering patient HRQoL when treating this condition.

Project description:Mycosis fungoides (MF) and Sézary syndrome (SS) are a distinct disease entity of cutaneous T-cell lymphoma with heterogenous clinical features and prognosis. MF mainly involves skin and usually shows an indolent and favorable clinical course. In patients with advanced-stage disease, extracutaneous involvement including lymph nodes, viscera, and blood, or large cell transformation may be observed. SS is a leukemic form of advanced-stage MF, characterized by generalized erythroderma. Early-stage MF can be treated with skin-directed therapy. However, patients with refractory or advanced-stage disease are associated with severe symptoms or poor prognosis, requiring systemic therapy. Recent progress in understanding the pathogenesis of MF/SS has contributed to advances in the management of these rare diseases. This review aims to describe the clinical manifestations, diagnosis, risk stratification, and treatment strategy of MF/SS, focusing on the recent updates in the management of these diseases.
