Announcement
Oragenics Inc announced that has completed a key study for their new concussion drug, ONP-002.
AI Summary
Oragenics Inc has completed an important study for its new concussion drug, ONP-002. The drug is delivered through the nose, which could allow it to quickly reach the brain after a head injury. In this study, scientists used a method called intranasal casting, where a metal model of the nose is used to see where the drug goes. The results showed that ONP-002 targets key areas in the nose that connect directly to the brain, increasing the likelihood that the medicine is effective in treating concussions. These promising findings have helped the company decide to move forward with Phase II human testing. If successful, the approach could help provide fast treatment for concussion patients, who receive their first dose of the drug within eight hours of injury.
