### Soligenix Advances Treating Rare Diseases with Dusquetide Designation

Soligenix, Inc. emerges as a key player in the biopharmaceutical landscape focused on rare diseases, announcing a significant milestone in the development of its candidate drug, dusquetide (SGX945). The European Medicines Agency’s Committee for Orphan Medicinal Products (COMP) has positively recommended orphan drug designation for dusquetide to treat Behçet’s Disease. This designation follows promising outcomes from a Phase 2a clinical trial that showcased both the efficacy and safety of dusquetide in patients suffering from this autoimmune condition. The recommendation from the EMA opens pathways to a potential 10-year marketing exclusivity in the EU upon final approval, offering not just protection but also incentives that could support the development stages of this important therapy.

Behçet’s Disease represents a considerable unmet need globally, affecting approximately 18,000 individuals in the U.S. and around 350,000 in Turkey, among others. This serious condition is marked by painful oral ulcers and systemic inflammatory responses, creating a significant impact on patients’ quality of life. The orphan designation signals growing recognition of the disease and reflects Soligenix’s commitment to addressing critical medical challenges. The approval also comes on the heels of similar designations by the FDA, which has previously awarded SGX945 orphan drug and fast track designations in the United States, underscoring the product's potential in the market.

CEO Dr. Christopher J. Schaber emphasizes the optimism surrounding dusquetide, noting its innovative mechanism as an innate defense regulator that modulates inflammatory responses. This advancement not only positions the drug as a critical treatment option for Behçet’s Disease but also enhances Soligenix’s intellectual property portfolio. With effective therapies often lacking for rare diseases, dusquetide's progression holds the promise of providing relief and improved outcomes for patients navigating the complexities of chronic conditions. The upcoming European Commission decision will be pivotal for Soligenix, further solidifying its role in the biopharmaceutical arena.

In addition to dusquetide, Soligenix continues to make strides in other therapeutic areas, including cutaneous T-cell lymphoma with its product HyBryte™ (SGX301) and further exploration with SGX302 for psoriasis. The company also remains committed to public health solutions, notably developing vaccines against ricin toxin, filoviruses, and COVID-19, showcasing its diversified approach to impactful healthcare solutions.

Soligenix is scheduled to present at the BIO Investment & Growth Summit in Miami Beach, providing a platform for potential collaborations and highlighting its innovative therapies and robust pipeline to investors and partners in the biopharmaceutical industry.
