Provides update on competitive positioning of Terra CoV-2 vaccine against SARS-CoV-2, expects to file IND in 3Q21

TAMPA, Fla.--(BUSINESS WIRE)-- Oragenics, Inc. (NYSE American: OGEN) today issued the following letter to stockholders from its President and Chief Executive Officer, Alan Joslyn, Ph.D.:

To My Fellow Stockholders,

With so much encouraging news recently around COVID-19 vaccine development, this is an excellent time to update you on Oragenics’ progress with our own vaccine, Terra CoV-2. Recent news heightens our confidence in our scientific approach. As a reminder, we added this vaccine candidate as a result of our May 2020 acquisition of Noachis Terra, and immediately began preclinical work. Noachis Terra is now a wholly-owned subsidiary of Oragenics.

Both Pfizer and Moderna have announced preliminary safety and efficacy data from their Phase 3 vaccine studies and recent Emergency Use Authorizations. We hold a nonexclusive intellectual property license from the National Institutes of Health (NIH) to the prefusion stabilized spike protein vaccine candidate. The Company’s license covers stabilizing the spike protein in the pre-fusion state, which may permit the number of immunogenic centers to be increased. This could allow for a greater likelihood of successful antibody binding, resulting in improved immunogenic responses. We believe that recent Phase 3 data reported relating to the Moderna vaccine supports the concept of utilizing the stabilized spike protein.

In terms of our development of Terra CoV-2, as recently announced we held a successful pre-Investigational New Drug (IND) meeting with the U.S. Food and Drug Administration (FDA), with agreements that allow us to save three to six months on pre-IND development timelines. The broad support for our approach by the FDA included a number of activities, including:

  • Use of the Research Cell Bank in the early manufacturing process development;
  • Use of early pilot batch manufacture under Good Manufacturing Processes (GMP) for the anticipated Phase 1 clinical trials; and,
  • Submission of draft toxicology reports during IND filing.

We are optimistic that our vaccine will ultimately prove to have several advantages.

  1. The NIH-created stabilized pre-fusion spike protein. The COVID-19 spike protein is a Class 1 fusion (S) protein which exists in a somewhat unstable but better immunogenic “prefusion” tertiary conformation, which in the process of receptor binding and fusion with a cell changes conformation to a more stable but weaker immunogenic post-fusion conformation. We believe that using the stabilized pre-fusion spike protein antigen will lead to a greater immune response as measured by neutralizing antibody titers.
  2. Access to a novel rationally designed adjuvant. We have recently signed an agreement with Adjuvance Technologies Inc. for the use of TQL1055, a novel, rationally designed semi-synthetic analogue of the saponin adjuvant QS-21 with potential improved attributes, including stability and manufacturing efficiency. We also anticipate that our Terra CoV-2 vaccine will provide long lasting protection from the SARS-CoV-2 virus with only one or two doses, with a more rapid immune response compared to vaccines developed without the inclusion of an adjuvant.
  3. Standard vaccine storage and distribution conditions. As presently designed, we believe the Terra CoV-2 vaccine permits cost effective storage and distribution at refrigerated temperatures, which should facilitate the distribution and thereby avoid challenges facing the two mRNA vaccines currently approved under Emergency Use Authorization in the U.S.

The creation of the Research Cell Bank is now complete and manufacturing has been transferred to our dedicated biologics contract development and manufacturing organization Avid Bioservices, Inc. for upstream and downstream processing. Creation of the Master Cell Bank, required for later stage manufacturing will begin in the coming weeks. This work supports our expectation to file the IND mid-year with commencement of patient enrollment in the Phase 1 clinical study immediately thereafter. The proposed Phase 1 study protocol is under development. We will provide details of the final protocol when the IND is approved.

While the world’s attention is on COVID-19, we also believe that our vaccine may provide some benefit against other coronaviruses that, unfortunately, may emerge or strengthen in the coming years.

In November and December of 2020, we completed financing transactions, raising cumulative gross proceeds of $12.5 million. These funds, when combined with our current cash and cash equivalents, should allow us to advance our vaccine through IND-enabling studies, including immunogenicity, viral challenge studies and the toxicology study. We also continue to pursue non-dilutive funding options as recommended by the Biomedical Advanced Research and Development Authority (BARDA). In late-September we announced that BARDA declined to provide funds to support the development of the Terra CoV-2 vaccine, but noted that evaluation of vaccine development under the Operation Warp Speed program, as well as other U.S. government-supported funding initiatives, can be an avenue for promising vaccine candidates, which we believe Terra CoV-2 to be.

We firmly believe that even with two or more vaccines projected to be on the market in the coming months, given the size of the worldwide pandemic there will be plenty of demand for the Terra CoV-2 vaccine, once development is successfully completed. Managing the global COVID-19 pandemic and follow up maintenance period will only be possible if multiple vaccines become available. Each will likely have its own particular efficacy characteristics, and each may have differences in manufacturing and distribution. We believe our Terra CoV-2 vaccine holds exceptional promise to play an important role in solving this crisis. We thank our stockholders, employees, partners and research scientists for their continued support, and look to the future with optimism and hope.

Sincerely,

Alan Joslyn
President and Chief Executive Officer
