Soligenix Announces Investor Webcast Event: Advantages of the CiVax™ Program for Development of a Broadly Distributed Heat Stable COVID-19 Vaccine
Soligenix, Inc. (SNGX) announced an Investor Webcast Event on September 10, 2020, to discuss its CiVax™ COVID-19 vaccine development using a thermostabilized glycoprotein platform. The prototype vaccine demonstrates strong immunity induction in preclinical studies, with notable safety in high-risk populations. Combined with its ability to remain stable at high temperatures, CiVax™ aims to meet urgent vaccination needs. Experts will present, followed by a Q&A session. The event invites questions beforehand and will provide a recording post-webcast.
- CiVax™ vaccine shows strong immune response in preclinical studies.
- Prototype induces immunity within 7 days of the initial dose.
- Vaccine platform allows for heat stability at over 100°F.
- None.
PRINCETON, N.J., Sept. 3, 2020 /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 hosting an Investor Webcast Event Thursday, September 10, 2020, from 4:00 – 5:00 pm Eastern Time on the use of its thermostabilized glycoprotein vaccine platform for the development of a COVID-19 vaccine, called CiVax™.
Utilizing a novel adjuvant, CoVaccine HT™, the platform has yielded a prototype vaccine with strong induction of both cell mediated and neutralizing antibody immunity in preclinical studies. More recent work with recombinant, affinity-purified SARS-CoV-2 Spike protein antigens have demonstrated similarly compelling data as well as an ability to induce a strong antibody response within 7 days of the initial vaccine dose. Combined with the previously demonstrated ability of this platform to produce heat stable vaccines at temperatures exceeding 100 degrees fahrenheit (40 degrees Celsius), which can be shipped and stored at ambient temperatures, as well as the accepted safety of protein vaccines also in higher-risk populations, such as the young, elderly and immunocompromised, the CiVax™ program has the potential to yield an easily distributed and broadly applicable vaccine to address both the immediate emergency of the COVID-19 pandemic and any potential need for future seasonal vaccinations. Preliminary results with the prototype vaccine are available at the following link: https://www.biorxiv.org/content/10.1101/2020.07.24.220715v1.
Conference Call Thursday, September 10 at 4:00 pm Eastern Time
The Company will share information on its thermostabilized glycoprotein vaccine platform for the development of a COVID-19 vaccine on Thursday, September 10, 2020 during a webcast event. A question and answer (Q&A) session with the featured experts and management will follow the presentations. If you would like to ask a question during the Q&A, please submit your request via email to ir@soligenix.com at least 15 minutes prior to the scheduled start of the call.

Featured Expert Biographical Background
Axel Lehrer, PhD
Axel Lehrer, Dr. rer. nat., Associate Professor, Department of Tropical Medicine, Medical Microbiology and Pharmacology, John A. Burns School of Medicine (JABSOM), University of Hawaiʻi at Mānoa (UHM). Dr. Lehrer has been researching vaccines since 2002 in both commercial and academic settings. He has primarily worked on developing vaccines for filoviruses such as Ebola virus, but also contributed to the development of flavivirus vaccines (Zika virus, Tick-borne encephalitis (TBE) virus, West Nile virus and Dengue virus). His research mostly employs recombinant viral subunits expressed and purified from an insect cell expression system. Dr. Lehrer's is trained in biochemistry, molecular biology, virology, as well as immunology and his research has received funding from NIH and other federal sources.
About CiVax™
CiVax™ is the Company's heat stable subunit vaccine candidate for the prevention of COVID-19, the infection caused by SARS-CoV-2. Under the Company's Public Health Solutions business segment, ongoing collaborations with Axel Lehrer, PhD of the Department of Tropical Medicine, Medical Microbiology and Pharmacology, JABSOM, UHM have demonstrated the feasibility of developing heat stable subunit filovirus vaccines, including hemorrhagic disease caused by Zaire ebolavirus, Sudan ebolavirus as well as Marburg marburgvirus, with both monovalent and bivalent vaccine combinations. Formulation conditions have been identified to enable heat stabilization of each antigen, alone or in combination, for at least 12 weeks at 40 degrees Celsius (104 degrees Fahrenheit). In March 2020, Soligenix and its collaborators expanded the technology platform to assess compatibility with vaccine candidates targeting SARS-CoV-2, the cause of COVID-19.
The vaccine platform includes three essential components:
1) a protein antigen, specifically a viral surface glycoprotein, which mediates entry and fusion of the virus with host cells and is manufactured with a proprietary insect cell expression system coupled with protein-specific affinity purification;
2) an adjuvant which has been shown to enhance both cell mediated and humoral immunity; and
3) a formulation which enables thermostabilization of the resulting mixture, avoiding the need for cold chain storage and shipping.
The resulting vaccine is broadly applicable, including to individuals often excluded from common viral vector vaccine approaches such as children, the elderly and the immunocompromised. The protection of elderly and immunocompromised populations are particularly important in the context of COVID-19. The ability to provide a thermostabilized, single vial vaccine, is particularly important in the context of rapid and broad vaccine distribution.
These same components are now being applied to coronavirus vaccine, using the well-defined surface glycoprotein, known as the Spike protein, as the antigen. Pre-clinical work in mice with a prototype vaccine recently have been made available, demonstrating the ability of the CoVaccine adjuvant in combination with a prototype antigen, to:
- stimulate immunity within 14 days after the first vaccination;
- induce a balanced Th1 response, believed to be critical to inducing immunity without aggravating disease pathology;
- induce a neutralizing antibody response; and
- induce a cell mediated immune response.
