Princeton, NJ - March 18, 2019 - 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 they will be presenting at the National Institutes of Health (NIH) - Commercialization Accelerator Program (CAP) 'FeedForward Session' in Washington, DC on March 21, 2019. The NIH selected Soligenix's SGX942 (dusquetide) development program for the treatment of oral mucositis in head and neck cancer (HNC) patients as a Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) Commercialization CAP Phase II awardee for 2018-2019. The SGX942 program was selected by the NIH specifically for the Commercialization Transition Track, which provides technical assistance to awardee companies to advance NIH-funded technologies towards commercialization and market readiness. The 'FeedForward Session' represents one of the final activities of this program with a presentation to a select group of NIH representatives, investor groups, and industry advisors.
Soligenix applied for the CAP as part of its $1.5 million Phase II SBIR/STTR NIH grant to develop SGX942 as a treatment for oral mucositis in HNC patients receiving chemoradiation therapy (CRT). Only a select number of SBIR Phase II awarded companies are accepted into the CAP by the NIH.
'We are appreciative of the NIH for selection into the Commercialization Accelerator Program and for their continued support of Soligenix and the SGX942 development program,' stated Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix. 'Oral mucositis remains an extremely debilitating side effect of cancer treatment and is particularly severe and prevalent in HNC patients. Soligenix looks forward to continuing work with NIH and to presenting at this invitation only event.'
Dusquetide (the active ingredient in SGX942) is an innate defense regulator (IDR), a new class of short, synthetic peptides with a novel mechanism of action modulating the body's reaction to both injury and infection towards a simultaneously anti-inflammatory and anti-infective response. By altering the response of the innate immune system, IDRs increase survival after infections caused by a broad range of bacterial Gram-negative and Gram-positive pathogens. They also accelerate resolution of tissue damage (including oral mucositis) following exposure to a variety of agents including bacterial pathogens, trauma and chemo- and/or radiation therapy.
Soligenix is working with leading oncology centers to advance dusquetide with the conduct of a Phase 3 clinical trial referred to as the 'DOM-INNATE' study (Dusquetide treatment in Oral Mucositis - by modulating INNATE immunity). Top-line results from this trial are targeted for the second half of 2019.
About Oral Mucositis
Mucositis is the clinical term for damage done to the mucosa by anticancer therapies. It can occur in any mucosal region, but is most commonly associated with the mouth, followed by the small intestine. It is estimated, based upon review of historic published studies and reports and an interpolation of data on the incidence of mucositis, that mucositis affects approximately 500,000 people in the US per year and occurs in 40% of patients receiving chemotherapy. Mucositis can be severely debilitating and can lead to infection, sepsis, the need for parenteral nutrition and narcotic analgesia. The gastrointestinal damage causes severe diarrhea. These symptoms can limit the doses and duration of cancer treatment, leading to sub-optimal treatment outcomes.
The mechanisms of mucositis have been extensively studied and have been recently linked to the interaction of chemotherapy and/or radiation therapy with the innate defense system. Bacterial infection of the ulcerative lesions is now regarded as a secondary consequence of dysregulated local inflammation triggered by therapy-induced cell death, rather than as the primary cause of the lesions.
It is estimated, based upon review of historic published studies and reports and an interpolation of data on the incidence of oral mucositis, that oral mucositis in HNC is a subpopulation of approximately 90,000 patients in the US, with a comparable number in Europe. Oral mucositis almost always occurs in patients with HNC treated with CRT and is severe, causing inability to eat and/or drink, in >80% of patients. It is common (40-100% incidence) in patients undergoing high dose chemotherapy and hematopoietic cell transplantation, where the incidence and severity of oral mucositis depends greatly on the nature of the conditioning regimen used for myeloablation.
Oral mucositis in HNC remains an area of unmet medical need where there are currently no approved drug therapies.
Dusquetide (the active ingredient in SGX942) is an 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 bacterial Gram-negative and Gram-positive pathogens. It 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 has been demonstrated in numerous animal disease models including mucositis, colitis, macrophage activation syndrome (MAS) as well as bacterial infections, including melioidosis.
SGX942 has demonstrated safety in a Phase 1 clinical study in 84 healthy human volunteers. Positive efficacy results were demonstrated in an exploratory Phase 2 clinical study in 111 patients with oral mucositis due to CRT for HNC. Soligenix is working with leading oncology centers in the US and Europe to advance SGX942 in oral mucositis with the conduct of a pivotal Phase 3 clinical trial referred to as the 'DOM-INNATE' study (Dusquetide treatment in Oral Mucositis - by modulating INNATE immunity).
SGX942 has received Fast Track Designation from the FDA for the treatment of oral mucositis as a result of radiation and/or chemotherapy treatment in HNC patients, as well as Promising Innovative Medicine designation in the United Kingdom by the Medicines and Healthcare Products Regulatory Agency for the treatment of severe oral mucositis in HNC patients receiving CRT. In addition, products containing the same active ingredient, dusquetide, have been granted Fast Track Designation as an adjunctive therapy with other antibacterial drugs, for the treatment of melioidosis and Orphan Drug Designations in the treatment of MAS and the treatment of acute radiation syndrome.
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. Soligenix has received partial funding from NIH for its oral mucositis clinical studies. The Phase 2 study was supported with a Phase I SBIR grant (#R43DE024032) award, with the Phase 3 study being supported by a Phase II SBIR grant (#R44DE024032) award.
Key nonclinical and clinical findings from the dusquetide program can be found in the following publications:
