Provided Update - August 14,2024

• Drug: ONP-002
• Announced Date: August 14, 2024
• Indication: To Treat Concussion

Oragenics, Inc. announced its lead candidate for treating concussion, ONP-002, is stable across a wide temperature range, eliminating the need for cumbersome cold storage for the drug device combination.

Oragenics, Inc. announced that its lead candidate for treating concussion, ONP-002, is stable across a wide range of temperatures. The stability of ONP-002, which remains over 99% pure for up to 3 months at temperatures from -20°C to 104°C, means it does not need cold storage. This breakthrough is important because cold chain storage can be difficult and impractical, especially during transport and in field conditions such as sports events and military operations. The drug is designed as a spray-dried powder delivered intranasally through a breath-propelled system, which helps it quickly reach the brain. This feature is crucial for treating concussions immediately and reducing long-term complications. The innovation could provide a much-needed treatment option for concussions, a condition affecting millions of people globally each year.

Provided Update - August 12,2024

• Drug: ONP-002
• Announced Date: August 12, 2024
• Indication: To Treat Concussion

Oragenics, Inc. announced its lead candidate for treating concussion, ONP-002, successfully completed a study that indicates it does not cause DNA damage and genotoxicity in an animal model.

Oragenics, Inc. announced that its lead concussion treatment candidate, ONP-002, has successfully completed an animal study showing it does not cause DNA damage or genotoxicity. The study was conducted under Good Laboratory Practice conditions, where multiple doses of ONP-002 were administered and the animal bone marrow was analyzed for genetic mutations and signs of disrupted cell division. The results indicated no cancer-causing DNA damage, suggesting that the drug does not interfere with the cell cycle. This finding is important because the FDA requires thorough preclinical testing to ensure that a pharmaceutical does not induce harmful genetic changes before it can proceed to clinical trials. Encouraged by these safety results, Oragenics plans to move forward with a Phase II clinical trial to further assess ONP-002 as a potential safe treatment for concussion patients.
