PRINCETON, N.J., Oct. 5, 2017 /PRNewswire/ -- 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 will be presenting the dusquetide
(SGX94) technology platform and its utility in various therapeutic
applications on October 9, 2017 at
the 2nd World Congress and Expo on Immunology taking
place in Chicago, IL from
October 9 - 11, 2017. The
presentation will discuss potential anti-inflammatory, tissue
healing, anti-infective and anti-tumor action, including data from
the recently completed Phase 2 trial in oral mucositis.
Details of the Oral Presentation:
Therapeutic Applications of Innate Immune Modulation presented by
Dr. Oreola Donini, Chief Scientific Officer on October 9, 2017 at 3:25 pm
Central Time. The abstract is available here.
Innate Defense Regulators (IDRs) modulate the innate immune
response and have the potential to play a significant role in
tissue healing, infection and cancer. IDRs, including the
lead clinical candidate dusquetide, have demonstrated preclinical
activity in bacterial infection models as both a stand-alone agent
and as a synergistic treatment with antibiotics, in tissue healing
models including oral mucositis and in tumor xenograft models.
Dusquetide has been demonstrated to be clinically effective
in modulating the innate immune system. In a Phase 2 clinical
trial in oral mucositis in which SGX942, Soligenix's product
candidate containing dusquetide, not only reduced the duration of
severe oral mucositis in response to chemotherapy and radiation
therapy induced tissue damage in head and neck cancer (HNC)
patients, but also reduced the incidence of infections in patients
treated with SGX942. In addition, patients receiving SGX942
were found to have an accelerated resolution of tumor burden and a
decreased mortality rate. Building upon positive Phase 2
data, Soligenix has recently initiated a pivotal Phase 3 clinical
trial with SGX942 in this patient population.
About the 2nd World Congress and Expo on
Immunology
The 2nd World Congress will host leading scientists
from academia and industry worldwide, to discuss the latest
developments in the fields of Immunology and Immune systems. The
conference aims to facilitate opportunities for exchanging ideas,
collaboration and networking with internationally renowned leaders
in immunology, to identify research and practice-based innovations
and to debate gaps and priorities for sustainable
development. Details on the congress can be found
here.
About Dusquetide
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 and an anti-infective
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, melioidosis, macrophage activation syndrome
(MAS) and other bacterial infections. Some of these
preclinical findings have been published in an article entitled "A
novel approach for emerging and antibiotic resistant infections:
Innate defense regulators as an agnostic therapy," available at the
following link:
http://dx.doi.org/10.1016/j.jbiotec.2016.03.032.
SGX942 has demonstrated safety in a Phase 1 clinical study in 84
healthy human volunteers. Recently, SGX942 had positive
results in an exploratory Phase 2 clinical study in 111 patients
with oral mucositis due to chemoradiation therapy (CRT) for
HNC. Consistent with preclinical findings, SGX942 at a dose
of 1.5 mg/kg demonstrated positive improvements in decreasing the
duration of severe oral mucositis by 50% overall compared to the
placebo group, from 18 days to 9 days (p=0.099). In patients
at the highest risk of developing severe oral mucositis (i.e.,
those receiving concomitant cisplatin chemotherapy of 80-100
mg/m2 every third week), the reduction in the duration
of severe oral mucositis was even more significant at 67% when
treated with SGX942 1.5 mg/kg, from 30 days to 10 days
(p=0.04). The p-values met the prospectively defined
statistical threshold of p<0.1 in the study protocol.
Additional observations included an improved tumor response to CRT
at the one month follow-up visit, as well as decreases in mortality
and infection rate. The study results are reviewed in
"Dusquetide: A Novel Innate Defense Regulator Demonstrating a
Significant and Consistent Reduction in the Duration of Oral
Mucositis in Preclinical Data and a Randomized, Placebo-Controlled
Phase 2 Clinical Study," published online in the Journal of
Biotechnology and available at the following link:
http://dx.doi.org/10.1016/j.jbiotec.2016.10.010.
Long-term (12 month) follow-up data further indicated the safety
and tolerability of SGX942 treatment, with a sustained trend
towards reduced mortality and increased tumor resolution in the 1.5
mg/kg SGX942 treatment group compared to the placebo group.
Opioid pain medication use was also seen to decrease over the
course of CRT in the 1.5 mg/kg SGX942 treatment group at the point
of highest oral mucositis risk, while it increased in the placebo
group. Detailed clinical results from the Phase 2 study, as
well as a review of the pathogenesis of oral mucositis and the
mechanism of action of SGX942, are discussed here. The long-term
follow-up results from the Phase 2 study are reviewed in,
"Dusquetide: Reduction in Oral Mucositis associated with Enduring
Ancillary Benefits in Tumor Resolution and Decreased Mortality in
Head and Neck Cancer Patients", published online in
Biotechnology Reports and available at the following link:
https://doi.org/10.1016/j.btre.2017.05.002.
Soligenix has received partial funding from NIDCR 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.
Drug products containing dusquetide have also received Fast
Track Designations from the FDA for the treatment of oral mucositis
as a result of radiation and/or chemotherapy treatment in HNC
patients, and as an adjunctive therapy with other antibacterial
drugs, for the treatment of melioidosis. Orphan Drug Designations
for use of dusquetide in the treatment of MAS as well as for the
treatment of acute radiation syndrome have also been granted. In
addition, dusquetide has been granted 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.
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.
