HyBryte™ Shows Promising Clinical Outcomes for CTCL Therapy

HyBryte™ Shows Continued Improvement Post-Treatment

Significant Efficacy against Plaque Lesions Also Demonstrated with HyBryte™

Soligenix, Inc. (NASDAQ: SNGX), a biopharmaceutical company dedicated to developing treatments for rare diseases, has shared promising results from a recent analysis of post-treatment data for its product, HyBryte™ (synthetic hypericin). The open-label study compared HyBryte™ to Valchlor (mechlorethamine), revealing that patients treated with HyBryte™ exhibited continued improvement in their lesions even after the cessation of treatment.

Key Study Findings

The study involved 10 patients who underwent 12 weeks of treatment followed by a 4-week observation period. Initial findings had already shown that 60% of the patients in the HyBryte™ group responded positively compared to just 20% in the Valchlor group. Remarkably, during the follow-up period, more than half of those treated with HyBryte™ maintained or even improved their treatment response by at least 10% at Week 16. In comparison, none of the Valchlor-treated patients showed similar improvements.

Impressive Results with Plaque Lesions

HyBryte™ demonstrated statistically significant improvements in the treatment of plaque lesions, which are difficult to manage and closely associated with disease progression. At the end of the treatment period, 63% of plaque lesions treated with HyBryte™ showed improvement, as opposed to only 17% in patients treated with Valchlor. By the follow-up period, these figures enhanced to 75% for HyBryte™ against 17% for Valchlor, reaffirming the efficacy of HyBryte™ in reducing plaque lesions and overall patient improvement.

Expert Insights

Dr. Brian Poligone, the Director of the Rochester Skin Lymphoma Medical Group and Principal Investigator of the study, expressed enthusiasm regarding the positive outcomes associated with HyBryte™. He noted that despite the small sample size, HyBryte™ exhibited a notable efficacy profile and safety compared to traditional therapies. He emphasized the drug's potential in addressing challenging lesions commonly seen in patients.

Significant Safety and Tolerance

One of the standout features of HyBryte™ is its safety profile during the study. No safety concerns were reported during both the treatment and follow-up phases. In contrast, the Valchlor group encountered various adverse events, including allergic reactions and skin sensitivity, which led to the withdrawal of some patients. These results underscore HyBryte™'s promise as a well-tolerated therapy for CTCL.

Continued Development Plans

Building on the positive results from prior clinical studies, Soligenix is focused on advancing the development of HyBryte™. Following the successful initial studies, the company is gearing up for a Phase 3 confirmatory study, FLASH2, which aims to enroll 80 patients to further validate the efficacy of HyBryte™ in treating early-stage CTCL. Christopher J. Schaber, PhD and CEO of Soligenix, noted that the rapid response exhibited by patients provides hope for effective CTCL management.

Understanding CTCL and Treatment Needs

Cutaneous T-Cell Lymphoma (CTCL) is a rare form of non-Hodgkin's lymphoma characterized by malignant T-cell proliferation in the skin. This cancerous growth can lead to considerable discomfort and, in severe cases, significant mortality. While current treatments help manage this disease, patients often experience recurrence, highlighting the need for safe and effective therapeutic options like HyBryte™.

About Soligenix and Their Commitment

Soligenix remains dedicated to developing innovative therapies for unmet medical needs. The company aims to leverage its expertise in biopharmaceutical development to bring HyBryte™ to market. Their ongoing research efforts are bolstered by positive feedback from regulatory authorities, emphasizing that safety and efficacy are paramount in their mission to combat CTCL.
