Oragenics to Participate in the World Vaccine Congress Washington

Oragenics, Inc. (NYSE American: OGEN) (“Oragenics” or the “Company”), a biotechnology company dedicated to fighting infectious diseases including COVID-19, announces that Kim Murphy, Chief Executive Officer, will be participating in the World Vaccine Congress Washington, being held April 3-6, 2023, in Washington, D.C.

Ms. Murphy will be holding meetings to highlight the company’s lead COVID-19 intranasal vaccine candidate, NT-CoV2-1, and to explore partnering opportunities. Oragenics recently reported favorable toxicology results confirming a safety and immunogenicity profile for NT-CoV2-1 that support plans to submit regulatory filings to proceed to a Phase 1 clinical study. Oragenics believes an intranasal COVID-19 vaccine holds several potential benefits compared with injectable vaccines, including targeting mucosal immunity, reducing transmission and offering a needle-free alternative for patients.

“I am excited to take part in the World Vaccine Congress this year and share our progress toward a highly differentiated intranasal COVID-19 vaccine,” said Ms. Murphy. “We expect strong interest among vaccine experts in this unique program and look forward to advancing to Phase 1 clinical trials in humans.”

Please contact tpatel@lhai.com or kmurphy@oragenics.com if you are interested in scheduling a meeting.

Earlier this month Oragenics entered into an exclusive global license agreement with Inspirevax Inc. for its novel intranasal mucosal adjuvant, BDX301. The company is currently evaluating formulation options for NT-CoV2-1 and is assessing various regulatory pathways to advance this program efficiently and thoughtfully.

In December 2022 Oragenics reported no toxicity signals or adverse events from its GLP toxicology study in rabbits evaluating the safety and immunogenicity of NT-CoV2-1. The study objectives were to evaluate potential toxicity following repeated intranasal administration at the maximal dose anticipated to be used in humans, and to confirm the immunogenicity of the vaccine.

Oragenics previously published positive preclinical data in Scientific Reports, a Nature journal, demonstrating that intranasal administration of NT-CoV2-1 induced robust antigen-specific IgG and IgA titers in the blood and lungs of mice, and reduced viral load below the limit of detection in a hamster SARS-CoV-2 challenge model. In both mice and hamsters, the antibodies had strong neutralizing activity, preventing the cellular binding of the viral spike protein based on the ancestral reference strain and variants of concern.
