Soligenix Announces Expansion of European Medical Advisory Board for Cutaneous T-Cell Lymphoma

Core Viewpoint - Soligenix, Inc. is expanding its European Medical Advisory Board to enhance strategic guidance for the Phase 3 study of HyBryte™ in treating cutaneous T-cell lymphoma (CTCL), with top-line results expected in the second half of 2026 [1][2]. Company Overview - Soligenix is a late-stage biopharmaceutical company focused on developing treatments for rare diseases with unmet medical needs, particularly through its Specialized BioTherapeutics segment [20]. - The company is advancing HyBryte™ (SGX301), a novel photodynamic therapy utilizing synthetic hypericin, aimed at treating CTCL [20]. Clinical Study Details - The confirmatory Phase 3 study, named FLASH2, will enroll approximately 80 patients and is designed to replicate the successful elements of the previous Phase 3 FLASH trial, which showed a 49% treatment response rate [15]. - The FLASH2 study will extend the double-blind, placebo-controlled assessment to 18 weeks, with the primary endpoint assessed at the end of this period [15]. Advisory Board Expansion - The European Medical Advisory Board now includes five esteemed dermatologists, enhancing the company's expertise in clinical strategies and regulatory interactions [2][3][4][7][8]. - The board members are recognized leaders in the field of dermatology and CTCL, contributing valuable insights for the upcoming clinical study [2][3][4][7][8]. Treatment Mechanism and Efficacy - HyBryte™ employs synthetic hypericin activated by visible light, which penetrates deeper into the skin compared to ultraviolet light, potentially treating more severe skin conditions [9]. - In previous studies, HyBryte™ demonstrated a statistically significant improvement in lesion reduction compared to placebo, with a 16% response rate in the first treatment cycle [10]. Safety Profile - HyBryte™ is noted for its safety, with no systemic absorption and a mechanism of action that does not involve DNA damage, making it a safer alternative to existing therapies [14]. - The treatment has been well tolerated across multiple cycles, with a significant portion of patients opting to continue treatment in the optional safety cycle [13]. Market Context - CTCL is a rare form of non-Hodgkin's lymphoma affecting approximately 31,000 individuals in the U.S. and 38,000 in Europe, with no current cure available [19][18]. - The company aims to address the significant safety risks associated with existing treatments, positioning HyBryte™ as a potentially safer and effective option for patients [14].
