Oragenics to Acquire Odyssey Health's Neurological Drug Technology Pipeline Including Concussion Drug Candidate

Gains Nasal Delivery Technologies and Expands Product Pipeline

Oragenics, Inc. (NYSE:OGEN) ("Oragenics" or the "Company") and Odyssey Health, Inc. (OTCQB:ODYY) ("Odyssey") announce the signing of a definitive agreement under which Oragenics will acquire Odyssey's assets related to its proprietary neurological drug therapies and technologies. The assets include drug candidates for treating mild traumatic brain injury (mTBI), also known as concussion, and for treating Niemann Pick Disease Type C (NPC), as well as Odyssey's proprietary powder formulation and its nasal delivery device. Odyssey will retain its other assets and operations.

The asset purchase includes cash payments to Odyssey totaling $1.0 million and eight (8) million shares of Oragenics' Series F Convertible Preferred Stock. The transaction is expected to close in the fourth quarter of 2023, subject to the satisfaction of various closing conditions, including approval of the transaction by Odyssey's shareholders and approval of the conversion of the Series F Preferred Stock by Oragenics' shareholders, of which there can be no assurances.

After closing this transaction, certain members of Odyssey management intend to join Oragenics and lead the continued development of Odyssey's pipeline of neurological drug therapies and technologies. Odyssey's technologies are expected to allow for easy nasal administration, rapid drug uptake to the brain, no cumbersome cold-chain protocols, and a strong safety profile, which hold potential to improve patient outcomes.

"We believe this strategic transaction could place Oragenics in a prime position to harness our expertise in intranasal administration, propelling us forward in neurological therapeutics. Our rigorous analysis of the underlying science and technologies has illuminated the immense potential of Odyssey's neurological assets, which could significantly expand our potential reach into a broader market. Concussions have reached epidemic proportions across sports, the military and among the elderly, with more than five million Americans affected annually. Shockingly, there remains no FDA-approved treatment for this condition," said Kim Murphy, President and Chief Executive Officer of Oragenics. "We are excited by the prospect of addressing some of the world's most pressing health challenges and evolving our company to enhance the lives of countless individuals."

Odyssey's lead concussion asset (ONP-002) is believed to be a first-in-class intranasal drug under development for the treatment of moderate-to-severe concussion in the acute through subacute phases. In preclinical animal studies, the asset demonstrated rapid and broad biodistribution throughout the brain while simultaneously reducing swelling, inflammation, and oxidative stress along with an excellent safety profile. Results from animals treated with the drug post-concussion showed positive behavioral outcomes using various testing platforms including improved memory and sensory-motor performance, and reduced anxiety. ONP-002 has completed a Phase 1 clinical trial showing it is safe and well tolerated in healthy human subjects. Odyssey and Oragenics are now preparing for Phase 2 clinical trials to further evaluate ONP-002's safety and efficacy.

"I look forward to working with Oragenics on further developing our assets," said Michael Redmond, President and Chief Executive Officer of Odyssey Health. "Our lead drug candidate for treating concussion has performed well in preclinical studies, generating promising efficacy and safety data in animal models. In addition, ONP-002 has completed a Phase 1 clinical study that concluded the drug is safe and well tolerated in humans. A pre-IND package has been submitted to the FDA for a Phase 2 trial and the collaboration with Oragenics allows for the advancement of these important neurological drug candidates."

About Mild Traumatic Brain Injury (mTBI)

Concussions are an unmet medical need that affect millions worldwide. Repetitive concussions can increase the risk of developing Chronic Traumatic Encephalopathy (CTE) and other neuropsychiatric disorders. It is estimated that 5 million concussions occur in the U.S. annually and that as many as 50% go unreported. The worldwide incidence of concussion is estimated at 69 million. The global market for concussion treatment was valued at $6.9 billion in 2020 and is forecast to reach $8.9 billion by 2027, according to Grandview Research. Common settings for concussion include contact sports, military training and operations, motor vehicle accidents, children at play and elderly assistive-living facilities due to falls.

About ONP-002

ONP-002 is a fully synthetic, non-naturally occurring neurosteroid being developed to treat mTBI (concussion). In preclinical studies, the drug demonstrated equivalent or better neuroprotective effects compared with related neurosteroids. Animal models of concussion showed the drug reduces the behavioral pathology associated with brain injury symptoms such as memory impairment, anxiety and motor/sensory performance. Additionally, ONP-002 is lipophilic and can easily cross the blood-brain barrier to rapidly eliminate swelling, oxidative stress and inflammation while restoring proper blood flow.

About Niemann-Pick Type C Disease

Niemann-Pick Type C (NPC) disease is a rare neurodegenerative genetic disorder characterized by the inability of cells to metabolize and properly transport cholesterol and other lipids, leading to the abnormal accumulation in various bodily tissues, including brain tissue. The NPC market is expected to grow from $128 million in 2022 to $188 million in 2031 across the U.S., Germany and U.K.
