Study DUS-AUBD-01 opens patient enrollment
PRINCETON, NJ, USA I November 14, 2024 I Soligenix, Inc. (Nasdaq: SNGX) (Soligenix or the Company), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today that it has opened patient enrollment for its Phase 2 study (protocol number DUS-AUBD-01) evaluating SGX945 (dusquetide) in the treatment of Behçet’s Disease.
“We are pleased to have received FDA clearance and Turkish Medicines and Medical Devices Agency (Turkey’s Ministry of Health) authorization to start patient enrollment into our SGX945 Phase 2a pilot trial in aphthous ulcers of Behçet’s Disease,” stated Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix. “Our previous studies with dusquetide in oral mucositis have validated the biologic activity in aphthous ulcers induced by chemotherapy and radiation. Given the role of the innate immune system in ulcers associated with Behçet’s Disease, and the unmet medical need particularly for more severe ulcers such as genital and leg ulcers, we believe that dusquetide may offer significant relief to patients. We are excited to expand dusquetide’s development into different innate immune-related inflammatory conditions, such as Behçet’s Disease, as a component of our long-term strategy to enhance the value of this unique compound. Behçet’s Disease is an area of unmet medical need, with up to 18,000 people in the U.S., 50,000 in Europe, 350,000 people in Turkey and as many as 1 million people worldwide affected by this incurable disease. Given the promising biologic activity observed with aphthous ulcers in oral mucositis, we are hopeful dusquetide will have a role to play in helping underserved patients suffering from this difficult to treat and chronic auto-immune disease. We look forward to completing enrollment and announcing study results in the first half of 2025.”
The pilot clinical trial of SGX945 will be an open-label study that will enroll approximately 25 patients age 18 years or older with mild to moderate Behçet’s Disease and active oral and/or genital ulcers. Patients will receive SGX945 as a twice weekly 4-minute intravenous (IV) infusion for 4 weeks followed by 4 weeks of follow-up. Efficacy endpoints will include the extent of lesion clearance, timeline to lesion clearance, and patient reported quality of life assessments.
About Dusquetide
Dusquetide, the active ingredient in SGX945 (Behçet’s Disease) and SGX942 (oral mucositis), is an innate defense regulator (IDR), a new class of short, synthetic peptides. It has a novel mechanism of action whereby it modulates the body’s reaction to both injury and infection towards an anti-inflammatory, anti-infective, and tissue healing response. IDRs have no direct antibiotic activity but, by modulating the host’s innate immune system responses, increase survival after infections caused by a broad range of Gram-negative and Gram-positive bacterial pathogens. Dusquetide also accelerates resolution of tissue damage following exposure to a variety of agents including bacterial pathogens, trauma, and chemo- and/or radiation therapy. Preclinical efficacy and safety have been demonstrated in numerous animal disease models including mucositis, colitis, macrophage activation syndrome as well as bacterial infections. In addition, potential anti-tumor activity has been demonstrated in multiple in vitro and in vivo xenograft studies.
Dusquetide has demonstrated safety and tolerability in a Phase 1 clinical study in 84 healthy human volunteers. In Phase 2 and 3 clinical studies with dusquetide in over 350 subjects with oral mucositis due to chemoradiation therapy for head and neck cancer, positive efficacy results were demonstrated, including potential long-term ancillary benefits.
Soligenix has a strong intellectual property position in the IDR technology platform, including composition of matter for dusquetide and related analogs. Dusquetide was developed pursuant to discoveries made by Professors B. Brett Finlay, PhD and Robert Hancock, PhD of the University of British Columbia, Canada.
About Behçet’s Disease
Behçet’s Disease is commonly known as an inflammatory disorder of the blood vessels (vasculitis). Often first diagnosed in young adults, its effects and severity will wax and wane over time. Major signs and symptoms usually include mouth sores (approximately 95% of patients), skin rashes and lesions (approximately 50% of patients), genital sores (approximately 50% of patients), leg ulcers (approximately 40% of patients) and eye inflammation (approximately 15% of patients). It is a painful disease, directly impacting the patient’s quality of life and ability to productively engage in life activities, including work.
Behçet’s Disease is thought to be an auto-immune disease with both genetic and environmental factors. It is most common along the “Silk Road” in the Middle East and East Asia, including Turkey, Iran, Japan and China. There are approximately 18,000 known cases of Behçet’s Disease in the U.S. and over 50,000 in Europe. There are as many as 1,000,000 people worldwide living with Behçet’s Disease.
There is no cure for Behçet’s Disease, rather treatments are prescribed to manage symptoms. Treatments may include both maintenance therapies and those specifically addressing flares (e.g., mouth ulcers, genital ulcers and leg ulcers). Corticosteroids are generally applied topically to sores and as eyedrops and may also be given systemically to reduce inflammation. Although used frequently, they have limited efficacy over the long-term and have significant side effects that become more concerning with more chronic use. Genital ulcers are often associated with significant genital scarring while leg ulcers can result in a post-thrombotic syndrome. Other treatments for Behçet’s Disease flares involve suppressing the immune system with drugs (e.g., cyclosporine or cyclophosphamide). These drugs come with a higher risk of infection, liver and kidney problems, low blood counts and high blood pressure. Finally, anti-inflammatory drugs are also used, including anti-TNF medications. The only approved drug in Behçet’s Disease is apremilast, which is used as a maintenance therapy to prevent formation of oral ulcers. Unfortunately, apremilast must be used continuously to be effective and is associated with both high cost and side effects including diarrhea, nausea, upper respiratory tract infection and headache.
About Soligenix
Soligenix is a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need. Our Specialized BioTherapeutics business segment is developing and moving toward potential commercialization of HyBryte™ (SGX301 or synthetic hypericin sodium) as a novel photodynamic therapy utilizing safe visible light for the treatment of cutaneous T-cell lymphoma (CTCL). With successful completion of the second Phase 3 study, regulatory approvals will be sought to support potential commercialization worldwide. Development programs in this business segment also include expansion of synthetic hypericin (SGX302) into psoriasis, our first-in-class innate defense regulator (IDR) technology, dusquetide (SGX942) for the treatment of inflammatory diseases, including oral mucositis in head and neck cancer, and (SGX945) in Behçet’s Disease.
Our Public Health Solutions business segment includes development programs for RiVax®, our ricin toxin vaccine candidate, as well as our vaccine programs targeting filoviruses (such as Marburg and Ebola) and CiVax™, our vaccine candidate for the prevention of COVID-19 (caused by SARS-CoV-2). The development of our vaccine programs incorporates the use of our proprietary heat stabilization platform technology, known as ThermoVax®. To date, this business segment has been supported with government grant and contract funding from the National Institute of Allergy and Infectious Diseases (NIAID), the Defense Threat Reduction Agency (DTRA) and the Biomedical Advanced Research and Development Authority (BARDA).
