Soligenix Inc. is advancing HyBryte, its late-stage therapy for cutaneous T-cell lymphoma (CTCL), a rare and chronic cancer that primarily affects older adults. HyBryte has shown strong promise as a first-line treatment option for early-stage CTCL, a market estimated at nearly $1 billion globally, with 70% of that opportunity in the U.S. The therapy has already received orphan drug designations in both the U.S. and Europe, as well as FDA Fast Track status. Unlike traditional treatments that can take a year or more to show efficacy, HyBryte demonstrated statistically significant results in just six weeks in its initial phase 3 trial. A second confirmatory phase 3 study, FLASH2, is now underway in the U.S. and Europe and is designed to provide further validation of HyBryte’s safety and effectiveness, with top-line results expected in 2026.

HyBryte's safety profile stands out in a treatment space where many existing options carry significant side effects, including DNA damage and long-term carcinogenic risks. The therapy’s use of synthetic hypericin activated by non-carcinogenic visible light — rather than ultraviolet light — offers a safer alternative, especially for older patients. With minimal systemic absorption and strong responses across both patch and plaque lesions, HyBryte has the potential to redefine the standard of care for CTCL. Soligenix's advancements in this rare disease area highlight the growing urgency and opportunity in addressing complex conditions that disproportionately affect aging populations.
