Soligenix Inc. has completed enrollment of the 50 patients required for the interim analysis in its confirmatory Phase 3 FLASH2 study evaluating HyBryte in cutaneous T-cell lymphoma. The interim analysis is scheduled for the second quarter of 2026, with topline data expected in the second half of the year. This milestone represents significant progress in the development of a novel treatment for this rare cancer.
The company reported an overall blinded response rate of 48 percent among patients who have completed treatment to date, substantially exceeding the anticipated 25 percent rate used in the study's powering assumptions. This strong efficacy signal suggests HyBryte may offer meaningful clinical benefit for patients with cutaneous T-cell lymphoma, a condition with limited treatment options. Investigators have noted safety findings consistent with earlier studies, maintaining the therapy's favorable risk-benefit profile.
HyBryte represents a novel photodynamic therapy approach that utilizes safe visible light rather than ultraviolet radiation, potentially offering a safer alternative to existing treatments. The successful completion of this second Phase 3 study could support regulatory approvals for commercialization worldwide, addressing a significant unmet medical need in the rare disease space.

The implications of this development extend beyond cutaneous T-cell lymphoma treatment. Soligenix is also exploring expansion of synthetic hypericin into psoriasis treatment, demonstrating the platform technology's potential across multiple therapeutic areas. The company's broader pipeline includes first-in-class innate defense regulator technology for inflammatory diseases and vaccine programs targeting various infectious diseases.
For the pharmaceutical industry, the progress in HyBryte development highlights continued innovation in rare disease therapeutics, particularly in oncology. The strong blinded response rate suggests potential for improved patient outcomes and could influence treatment paradigms for cutaneous T-cell lymphoma. The successful advancement of this program may also validate Soligenix's approach to rare disease drug development, potentially attracting additional investment and partnership opportunities in the biopharmaceutical sector.
Patients with cutaneous T-cell lymphoma face limited treatment options, and the development of HyBryte represents hope for improved therapeutic alternatives. The therapy's novel mechanism of action and demonstrated safety profile could position it as an important addition to the treatment landscape if regulatory approvals are secured following study completion. The ongoing development program continues to show encouraging efficacy signals that warrant continued investigation and potential clinical application.
