Oragenics Announces Favorable Preliminary Toxicology Data for Intranasal COVID-19 Vaccine Candidate

• N T-CoV2-1 preliminary data supports regulatory filings for Phase 1 studies
• Intranasal administration elicits immune responses

Oragenics, Inc. (NYSE American: OGEN) (“Oragenics” or the “Company”), a biotech company dedicated to fighting infectious diseases including COVID-19, today announced favorable preliminary results from its ongoing Good Laboratory Practice (GLP) toxicology study to evaluate the safety profile and immunogenicity of its NT-CoV2-1 vaccine candidate in rabbits. These initial results continue to demonstrate a safety profile and immune responses that the Company believes will support regulatory filings required to progress to a Phase 1 clinical study. The final toxicology report, including ongoing histopathology evaluation, is expected by year-end.

“With new variants of COVID-19 continuously arising and presenting more aggressive transmission, there is a need for novel protective vaccines,” said Kimberly Murphy, President and CEO. “We believe our intranasal vaccine candidate will have the potential to reduce transmission and offers a needle-free COVID-19 vaccine option. Our intranasal vaccine candidate has previously shown strong immune responses in preclinical studies against multiple SARS-CoV-2 variants of interest. We expect to initiate our Phase 1 clinical study by early 2023.”

The objectives of this ongoing toxicology study are to evaluate the potential toxicity of NT-CoV2-1 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 was highly efficacious in a hamster SARS-CoV-2 challenge model, reducing the viral load below the limit of detection. 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.
