Cutaneous T-cell Lymphoma market size is projected to grow at a CAGR of 5.0% by 2034

In 2025, the Cutaneous T-Cell Lymphoma (CTCL) market size across the 7MM was valued at approximately USD 1,042 million and is projected to expand at a CAGR of 5.0%, reaching around USD 1,622 million by 2034. Among these markets, the United States held the dominant position in 2024, capturing nearly 70% of the total CTCL market share within the 7MM. DelveInsight’s comprehensive market research provides critical insights into such market trends, enabling stakeholders to understand growth drivers, emerging opportunities, and potential challenges within the Cutaneous T-cell Lymphoma landscape.

In 2024, the United States reported the highest number of Cutaneous T-Cell Lymphoma (CTCL) cases among the 7MM, with approximately 3,050 cases, and this number is projected to rise by 2034. Across the 7MM, there were around 7,250 total incident CTCL cases in 2024, with a higher prevalence among males. In the U.S., mycosis fungoides represented the most common CTCL subtype. Within the EU4 and the UK, Germany recorded the highest number of cases, estimated at around 760 in 2024.

Approved therapies for Cutaneous T-cell Lymphoma (CTCL) encompass various mechanisms of action (MoA), including CCR4 inhibitors (POTELIGEO), CD30-targeted antibody-drug conjugates (ADCETRIS), HDAC inhibitors (ZOLINZA), and retinoids (TARGRETIN), providing a diverse range of treatment options.

KINSELBY (4SC), an investigational oral HDAC inhibitor, received a negative opinion from the Committee for Medicinal Products for Human Use (CHMP) regarding its Marketing Authorization Application (MAA), resulting in the discontinuation of its development and commercialization efforts. Cutaneous T-cell lymphomas (CTCLs) are a diverse group of extranodal non-Hodgkin lymphomas (NHL) arising from mature, skin-targeting T cells that primarily affect the skin. The predominant subtypes, mycosis fungoides and primary cutaneous CD30+ anaplastic large cell lymphoma (pcALCL), together account for approximately 80–85% of all CTCL cases.

Cutaneous T-cell Lymphoma Overview

Cutaneous T-cell lymphoma (CTCL) is a rare type of non-Hodgkin lymphoma that primarily affects the skin. It arises when T-cells (a type of white blood cell) become cancerous and target the skin, leading to red, scaly patches, plaques, or tumors. The most common forms of CTCL include Mycosis Fungoides and Sézary Syndrome. While it often progresses slowly, advanced stages may affect lymph nodes, blood, and internal organs. Treatment depends on the disease stage and may involve topical therapies, phototherapy, systemic medications, or immunotherapy.

Recent Development In The Cutaneous T-cell Lymphoma Treatment Landscape:

• In October 2025, Soligenix, Inc. (Nasdaq: SNGX), a late-stage biopharmaceutical company dedicated to developing treatments for rare diseases with unmet medical needs, announced the completion of its first Data Monitoring Committee (DMC) review for the confirmatory Phase 3 trial evaluating HyBryte™ (synthetic hypericin) in Cutaneous T-cell Lymphoma (CTCL). The DMC found no safety issues, confirming that HyBryte™ maintains a favorable safety profile consistent with earlier clinical data. The ongoing Phase 3 FLASH2 (Fluorescent Light Activated Synthetic Hypericin 2) study builds upon the successful prior Phase 3 (FLASH) trial, a comparative study (HPN-CTCL-04), and an investigator-initiated study (RW-HPN-MF-01). With steady enrollment progress, Soligenix expects to provide an update in Q4 2025 and plans a pre-specified blinded interim efficacy analysis in the first half of 2026.
• In May 2025, Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) announced that it will present long-term follow-up data from the Phase 2 TELLOMAK trial evaluating lacutamab, an anti-KIR3DL2 monoclonal antibody, in patients with Sézary syndrome (SS) and mycosis fungoides (MF)—two rare and aggressive forms of cutaneous T-cell lymphoma (CTCL). The results will be presented at the upcoming American Society of Clinical Oncology (ASCO) 2025 Annual Meeting in Chicago, Illinois.
• In April 2025, Interim findings from the ongoing FLASH2 study (NCT06470451) demonstrate that SGX301 (HyBryte) continues to show strong potential in treating early-stage cutaneous T-cell lymphoma (CTCL). Of the first nine enrolled patients, complete week 18 data were available for eight, and 75% achieved “treatment success” by week 18. Treatment success was defined as a ≥50% reduction from baseline in the cumulative modified Composite Assessment of Index Lesion Severity (mCAILS) score, with six out of eight evaluable patients meeting this benchmark, reflecting promising therapeutic outcomes.
• In February 2025, Innate Pharma has been granted Breakthrough Therapy Designation (BTD) by the U.S. Food and Drug Administration (FDA) for its lead candidate, lacutamab, aimed at treating adults with relapsed or refractory Sézary syndrome. Lacutamab is an innovative monoclonal antibody that selectively targets the killer cell immunoglobulin-like receptor 3DL2 (KIR3DL2) to induce cytotoxic responses. The therapy is currently being evaluated in clinical trials for its potential effectiveness in treating cutaneous T-cell lymphoma (CTCL) and peripheral T-cell lymphoma (PTCL).
• In January 2025, Interim findings from the investigator-initiated Phase 2 RW-HPN-MF-01 trial (NCT05872854), reported by Soligenix, revealed that treatment with synthetic hypericin (HyBryte) for up to 12 months produced positive clinical responses in patients with early-stage cutaneous T-cell lymphoma (CTCL).
• In January 2025, 4SC AG reported that it has successfully submitted its responses to the European Medicines Agency (EMA) Day-120 List of Questions in December 2024, as planned, following the initial Marketing Authorisation Application (MAA) for resminostat (Kinselby) filed in March 2024.
• In January 2025, Soligenix, Inc. (Nasdaq: SNGX), a late-stage biopharmaceutical company focused on developing therapies for rare diseases with high unmet needs, provided an interim update from an open-label, investigator-initiated study evaluating HyBryte™ (synthetic hypericin) for up to 12 months in patients with early-stage cutaneous T-cell lymphoma (CTCL). The study is led by Dr. Ellen Kim, Director of the Penn Cutaneous Lymphoma Program and Professor of Dermatology at the Hospital of the University of Pennsylvania, who also served as a lead investigator in the Phase 3 FLASH trial of HyBryte™ in early-stage CTCL.
• In December 2024, Soligenix, Inc. (Nasdaq: SNGX), a late-stage biopharmaceutical company focused on developing and commercializing therapies for rare diseases with high unmet needs, has announced the initiation of patient enrollment for its confirmatory Phase 3 clinical trial of HyBryte™ (synthetic hypericin) for the treatment of cutaneous T-cell lymphoma (CTCL). This new study, titled FLASH2 (Fluorescent Light Activated Synthetic Hypericin 2), is designed to validate findings from the prior statistically significant Phase 3 FLASH trial. It is further supported by data from a recent successful comparative study (HPN-CTCL-04) and an ongoing investigator-initiated trial, reinforcing the trial’s foundation.
