Figure S1: CCR4 immunohistochemical staining before mogamulizumab treatment, during mogamulizumab treatment, and in residual nodules after completion of therapy. Prior to mogamulizumab treatment, CCR4+ cells were observed in both the epidermis and dermis. During treatment and in the residual nodules after completion, a small number of CCR4+ cells were observed only in the dermis. Figure S2: Double immunofluorescence staining findings. In CD4/CD8 staining, CD8+ cells were predominant in pre-ulcerative lesions, and only CD8+ cells were detected in peri-ulcerative lesions. Both CD4 and CD8 were negative in ulcerative lesions. In CD8/Granzyme B staining, both CD8 and Granzyme B were abundantly expressed in pre-ulcerative lesions, while Granzyme B was reduced in peri-ulcerative lesions. Both markers were undetectable in ulcerative lesions. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.

A historical review of mycosis fungoides: from Alibert to mogamulizumab

Review

Author: Venables, Zoe ; Fariyike, Opeoluwa ; Johnson, Nicholas A ; Mistry, Khaylen ; Levell, Nick J

Abstract:

In 1806, French physician Baron Jean-Louis Alibert saw a man with a desquamating rash and skin tumours. Alibert considered this to be a variant of yaws. In 1829 Alibert named the condition mycosis fungoides (MF), meaning ‘mushroom-like fungal disease’. Over 100 years later, French dermatologist Albert Sézary published papers from 1938 to 1949 detailing a mysterious disease containing ‘cellules monstrueuses’, describing cutaneous ‘monster cells’. In 1961, these clinical findings were collated together into ‘Sézary syndrome’. In the 1870s English dermatologist William Tilbury Fox published a dermatology atlas detailing cases similar to what we know now as MF, with the name ‘fibroma fungoides’. The atlas described MF as a type of fungus, before giving a description of yaws and painting a clinical picture that differed from that of a lymphoma. Over the twentieth century, our understandings of the origins of MF were changing and by 1975 the classification system and term we now recognize as cutaneous T-cell lymphoma (CTCL) was developed. Neoplastic cells have been thought to arise from chronic activation of T cells via antigen-presenting cells due to inappropriate cytokines and C-C chemokine receptors. In 2018, the World Health Organization and European Organisation for Research and Treatment of Cancer officially recognized four variants of MF. These are the classic Alibert–Bazin variant and its three variants: folliculotropic MF, pagetoid reticulosis and granulomatous slack skin. Developments in immunohistochemistry for the T-cell receptor gene in the 1990s improved the diagnosis of CTCL; however, diagnosis is still challenging. Advanced MF therapies have evolved from cytotoxic chemotherapy to novel monoclonal antibodies such as mogamulizumab, targeting proteins on T-cell lymphoma cells.

Innate Pharma Announces FDA Clearance to Proceed With TELLOMAK 3, a Confirmatory Phase 3 Trial of Lacutamab in CTCL

MARSEILLE, France--(BUSINESS WIRE)--Regulatory News: Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced that the U.S. Food and Drug Administration (FDA) has completed its review of the confirmatory Phase 3 protocol for lacutamab in cutaneous T-cell lymphomas (CTCL), with no further comments, clearing the trial to proceed. The planned confirmatory Phase 3 trial, TELLOMAK 3, is an open-label, randomized study designed to demonstrate the efficacy of lacutamab in patients with Sézary syndrome and Mycosis fungoides, who failed at least one prior line of systemic therapy. The trial will include two independent cohorts: one enrolling patients with Sézary syndrome post-mogamulizumab treatment randomized 1:1 to receive lacutamab or romidepsin, and one enrolling patients with Mycosis fungoides randomized 1:1 to receive lacutamab or mogamulizumab. The primary endpoint of the study for both cohorts is progression-free survival (PFS) evaluated by blinded central review. Data from the Phase 2 TELLOMAK trial in CTCL demonstrated durable activity, a favorable safety profile, and improvements in patients’ quality of life. With this feedback from FDA, the Company is progressing towards the initiation of the confirmatory Phase 3 TELLOMAK 3 trial in H1 2026. FDA provided encouraging initial feedback on Innate Pharma’s proposed regulatory pathway, which could potentially include Accelerated Approval for Sézary syndrome, once the Phase 3 trial is underway. “This important regulatory milestone with the FDA marks a key step forward for the lacutamab program,” said Jonathan Dickinson, Chief Executive Officer of Innate Pharma. “Building on robust Phase 2 data from TELLOMAK, this milestone brings us one step closer to our next goal, submitting for accelerated approval in Sézary syndrome once the Phase 3 trial is underway. We remain deeply committed to advancing this differentiated therapy for patients with CTCL, while creating meaningful value for our shareholders.” “We are pleased to reach this important milestone for the lacutamab program as we prepare to initiate the confirmatory Phase 3 study, TELLOMAK 3,” said Sonia Quaratino, Chief Medical Officer of Innate Pharma. “The efficacy and safety data from the TELLOMAK Phase 2 trial suggest that lacutamab has the potential to be a game changer in the treatment of CTCL, an orphan disease with a high unmet medical need. Our expert clinical team looks forward to collaborating with CTCL investigators and regulators to start the Phase 3 trial in due time.” About lacutamab Lacutamab is a first-in-class anti-KIR3DL2 antibody, currently developed in cutaneous T-cell lymphoma (CTCL) and peripheral T-cell lymphoma (PTCL). CTCL is a group of rare non-Hodgkin’s lymphomas that develop in the skin and severely affect patients’ quality of life. Sezary syndrome (SS) is a rare and aggressive leukemic form with poor survival, while mycosis fungoides (MF) is the most common subtype, with advanced stages associated with poor outcomes. Data from the Phase 2 TELLOMAK trial in CTCL demonstrated durable activity, a favorable safety profile, and improvements in patients’ quality of life. FDA provided encouraging initial feedback on Innate Pharma’s proposed regulatory pathway, which could potentially include Accelerated Approval for Sézary syndrome. The program has received Fast Track designation from the FDA, PRIME designation from the EMA for SS, and Orphan Drug designation in both the US and EU for CTCL.

Kyowa Kirin and University Hospitals Birmingham announce new survival data in rare disease study

Kyowa Kirin, the European subsidiary of the Japan-based specialty pharmaceutical company, and University Hospitals Birmingham NHS Foundation Trust have announced new findings from the ongoing PROCLIPI study on the treatment of cutaneous T cell lymphoma (CTCL) using POTELIGEO (mogamulizumab). The PROCLIPI (PROgnostic Cutaneous Lymphoma International Prognostic Index) study is a prospective, observational, multicentre registry that now includes more than 2,000 patients across 19 countries – making it one of the largest CTCL data sets worldwide. Its primary objective is to collect robust clinical data to support the development of prognostic indices for CTCL. “The PROCLIPI Study demonstrates the power of global collaboration in rare diseases. By bringing together data from across the world, we can generate insights that simply wouldn’t be possible in isolation,” said Professor Julia Scarisbrick, Chief Investigator of the PROCLIPI Study and Honorary Professor of Dermatology, University Hospitals Birmingham NHS Foundation Trust. “We are working to build rigorous scientific evidence while giving patients and their families a better understanding of what long-term survival looks like.” The latest results, presented at the European Organisation for Research and Treatment of Cancer – Cutaneous Lymphoma Tumour Group (EORTC-CLTG) Annual Meeting in Athens, Greece, focused on overall survival (OS) outcomes. Findings showed that POTELIGEO was associated with statistically significant and clinically meaningful improvements in median OS among patients with mycosis fungoides (MF) and Sézary syndrome (SS) – two rare CTCL subtypes, which is itself a rare form of non-Hodgkin’s lymphoma that remains treatable but not curable. “These insights into improved overall survival for patients living with CTCL mark an important step forward, providing a stronger clinical evidence base and reinforcing the value of international networks in rare disease research,” says Dr Nick Kronfeld, Head of Medical Affairs, Kyowa Kirin International. “By working alongside scientific and patient communities in CTCL, we can gain a better understanding of real-world outcomes, enabling us to bring life-changing value to patients and families, not just today but over the long term.”

Global Registry Data Show Meaningful Overall Survival Benefit in Patients with Advanced Cutaneous T-cell Lymphoma (CTCL) treated with POTELIGEO (mogamulizumab)

GALASHIELS & MARLOW, & BIRMINGHAM, United Kingdom--(BUSINESS WIRE)--Kyowa Kirin International (KKI), a wholly owned subsidiary of Kyowa Kirin Co., Ltd. (TSE:4151, Kyowa Kirin), a Japan-based global specialty pharmaceutical company, and the University Hospitals Birmingham NHS Foundation Trust, today announced new overall survival (OS) insights from the PROCLIPI (PROgnostic Cutaneous Lymphoma International Prognostic Index) Study aligning with previous findings that suggest mogamulizumab may offer meaningful OS benefit for patients living with mycosis fungoides (MF) and Sézary syndrome (SS), two rare conditions and subtypes of cutaneous T-cell lymphoma (CTCL).2 Key findings2: For patients with advanced-stage MF and SS (n=371), the median overall survival from the onset of treatment was higher for patients treated with mogamulizumab (n=72) at 64 months compared with those not receiving mogamulizumab (n=175) at 54 months (p<0.01). Patients treated with mogamulizumab showed a trend toward improved OS compared to those not receiving mogamulizumab across risk-stratified groups according to the new Cutaneous Lymphoma International Prognostic Index (CLIPI). For a subset of patients with SS (n=96), the median OS is around 6.5 years for patients treated with mogamulizumab (n=46) compared with around 3 years for systemic treatment but not mogamulizumab (n=50) (p<0.01). This research was presented as part of the Scientific Proceedings at this year’s European Organisation for Research and Treatment of Cancer Cutaneous Lymphoma Tumour Group (EORTC-CLTG) Annual Meeting in Athens, Greece.2 The data contributes to a growing body of evidence suggesting potential OS benefits with mogamulizumab, 4,5 highlighting the importance of collaboration across the CTCL community in advancing understanding of survival outcomes and helping to shape the future of patient care. “The PROCLIPI Study demonstrates the power of global collaboration in rare diseases. By bringing together data from across the world, we can generate insights that simply wouldn’t be possible in isolation,” says Professor Julia Scarisbrick, Chief Investigator of the PROCLIPI Study and Honorary Professor of Dermatology, University Hospitals Birmingham NHS Foundation Trust. “We are proud to coordinate this initiative as we’re working to build rigorous scientific evidence while giving patients and their families a better understanding of what long-term survival looks like.” The PROCLIPI Study, now in its tenth year, aims to develop prognostic indices for MF and SS. The study collects comprehensive data, including clinical, haematological, pathological, imaging, treatment with responses, quality of life and survival data.1 Recently, a new prognostic index (CLIPI) for advanced CTCL was published to enable precise patient risk stratification.6 “For those of us in the CTCL community, survival isn’t just about numbers on a chart - it’s about being able to spend more time with our families, plan for the future, and live life with dignity”, says Susan Thornton, CEO, Cutaneous Lymphoma Foundation. “That’s why initiatives like PROCLIPI are important, as the data collected reflects real lived experiences and can help inform future improvements in care for patients.” The independent international PROCLIPI Study aligns with Kyowa Kirin International’s commitment to generating real-world insights that advance the understanding of CTCL and turn these clinical insights into meaningful improvements in access, policy, and patient care. Cutaneous T-cell lymphoma is a rare disease7, and innovation in this environment can be challenging due to the rarity of this disease.8 Yet despite these challenges, mounting evidence continues to emerge4,5 to help strengthen our collective understanding of potential treatment benefits. “These insights into improved overall survival for patients living with CTCL mark an important step forward, providing a stronger clinical evidence base and reinforcing the value of international networks in rare disease research,” says Dr Nick Kronfeld, Head of Medical Affairs, Kyowa Kirin International. “By working alongside scientific and patient communities in CTCL, we can gain a better understanding of real-world outcomes, enabling us to bring life-changing value to patients and families, not just today but over the long term.” Note to editors The OS data from the PROCLIPI Study was presented as an oral presentation during the EORTC CTCL Annual Group Meeting 2025. 2 KKI did not sponsor the PROCLIPI study or OS analysis. The median OS for patients (n=72) receiving mogamulizumab compared to those not receiving mogamulizumab (n=175) was 64 months versus 54 months. 2 Median OS data amongst risk stratifications according to CLIPI: 2,6 Low-risk: 67 months vs. ‘not reached’ for mogamulizumab versus those who had not received mogamulizumab Medium-risk: 64 vs. 48 months for mogamulizumab versus those who had not received mogamulizumab High-risk: 26 vs. 13 months for mogamulizumab and for those who had not received mogamulizumab Low-risk: 67 months vs. ‘not reached’ for mogamulizumab versus those who had not received mogamulizumab Medium-risk: 64 vs. 48 months for mogamulizumab versus those who had not received mogamulizumab High-risk: 26 vs. 13 months for mogamulizumab and for those who had not received mogamulizumab About Kyowa Kirin Kyowa Kirin aims to discover novel medicines with life-changing value.

About PROCLIPI PROCLIPI is the PROgnostic Cutaneous Lymphoma International Prognostic Index Study with the main aim to produce a prognostic index in mycosis fungoides (MF) and Sezary syndrome (SS). The study prospectively collects clinical, haematological, pathological, imaging, treatment with responses, quality of life and survival data using careful predefined datasets. Patients are subject to a central review to confirm diagnosis. PROCLIPI opened in 2015 and recruitment has been strong with to date over 2,000 patients recruited from 52 Centres from 19 countries across 6 continents.1 This trial was registered at www.ClinicalTrials.gov NCT02848274.3 About MF and SS MF and SS are two subtypes of CTCL, which is itself a rare form of non-Hodgkin’s lymphoma that presents and persists in the skin.7 CTCL is treatable, but is not generally considered to be curable, and there has been a clear unmet need for novel treatment options. As well as the obvious impact of symptoms upon patients, there can be significant erosions to quality of life for those caring for an individual living with CTCL.9 MF and SS are characterised by localisation of cancerous white blood cells called T lymphocytes (T cells), to the skin.10 These cancerous T cells consistently express a protein called CCR4, which enables them to move from the blood to the skin.11-13 When these cancerous T cells move to the skin, this results in the visible early skin symptoms of red patches or plaques which can resemble psoriasis or eczema in the early stages of the disease.14 Later, for some patients, skin involvement may evolve to include tumours or reddening of the majority of the skin’s surface (erythroderma). MF—the most common CTCL subtype—accounts for approximately 60% of all CTCLs15 and is typically indolent, characterised by skin symptoms including patches or plaques, skin redness and tumours. SS is much rarer, accounting for around 5% of CTCLs,16 and is more aggressive,14 with high levels of blood involvement.16 It can cause severe itching, erythroderma, intense scaling of the skin and hair loss.14 CTCL can take, on average, between 2 and 7 years for individuals to receive a confirmed diagnosis.14 About Poteligeo (mogamulizumab) Mogamulizumab is a first-in-class humanised monoclonal antibody directed against CC-chemokine receptor 4 (CCR4), a protein consistently expressed on cancerous cells seen in both MF and SS. 11-13 Once mogamulizumab binds to CCR4, it increases attraction of immune cells from the immune system to destroy the cancerous cells.17 References 1 Scarisbrick, J.
