Oragenics Provides Update on SARS-CoV-2 (COVID-19) Program

Oragenics, Inc. (NYSE American: OGEN) (“Oragenics” or “the Company”) today provided an update on progress with its SARS-CoV-2 (COVID-19) vaccine candidate and announced the termination of its clinical development program with AG013 for the treatment of severe oral mucositis in cancer patients.

While working with Aragen Bioscience, a leading contract research organization focused on accelerating preclinical biologics product development, to advance the Company’s recently acquired COVID-19 vaccine candidate, TerraCoV2, the National Institutes of Health-created stabilized pre-fusion spike protein gene has been successfully inserted into Chinese Hamster Cells (“CHO”) and “mini-pool” production and analytical development are underway. The transfer to full-scale manufacture is expected to commence later this summer.

Separately, following a further review of new data and other factors related to the Company’s international multicenter Phase 2 clinical trial of AG013 in oral mucositis, Oragenics has determined to cease further development of AG013 in this indication by discontinuing the trial and withdrawing the applicable Investigational New Drug application. As a result, on July 9, 2020, the Company, Precigen, Inc. (“Precigen”) and Precigen’s wholly owned subsidiary mutually agreed to terminate the Exclusive Channel Collaboration (“ECC”) agreement for AG013 as a treatment of severe oral mucositis in cancer patients. The Company expects to continue to comply with any applicable regulatory requirements with respect to discontinuing the clinical trial.

“As we await Biomedical Advanced Research and Development Authority (“BARDA”) and other federal and state non-dilutive grant decisions, we expect to use our available cash to continue development of TerraCoV2, with the goal of bringing this COVID-19 vaccine candidate into human clinical trials by early 2021,” said Alan Joslyn, Ph.D., President and CEO of Oragenics. “Although the Phase 2 AG013 clinical trial demonstrated activity in certain patient populations, the overall lack of efficacy along with other factors, inclusive of strategic product portfolio considerations, led us to the decision to discontinue further development of AG013 under the ECC.”
