Post-Concussion Syndrome

SARASOTA, Fla.--(BUSINESS WIRE)-- Oragenics, Inc. (NYSE American: OGEN), a company focused on developing unique, intranasal pharmaceuticals for the treatment of neurological disorders, today announced it has appointed Dr. James “Jim” Kelly, Neurologist, as its Chief Medical Officer, to oversee its upcoming Phase II clinical trial. Oragenics’ lead drug candidate, ONP-002 is combined with its intranasal device intended for the treatment of mild Traumatic Brain Injury (TBI), aka concussion. ONP-002 is a new chemical entity (NCE) designed to target the brain through delivery into the nasal cavity and onward to the brain. A 40-patient Phase I study was completed and showed the drug to be safe and well-tolerated. In the recent past, Dr. Kelly served as the Executive Director of the Marcus Institute for Brain Health (MIBH) and Professor of Neurology at the University of Colorado Anschutz Medical Campus in Aurora, Colorado. The MIBH specialized treatment program is funded by the Marcus Foundation to care for US military veterans with persistent symptoms of TBI. Dr. Kelly was also National Director of the Avalon Action Alliance TBI Programs for which the MIBH serves as the clinical coordinating center. “I am excited to join Oragenics as its Chief Medical Officer at such an important and pivotal time in the drug development process. I have been involved with the drug for many years now and look forward to testing the drug and showing it can improve patient outcomes in our upcoming Phase II clinical trials,” said Dr. Kelly. Prior to these recent positions, Dr. Kelly was the Director of the National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center in Bethesda, MD. As its founding Director, he led the creation of an innovative interdisciplinary team of healthcare professionals who blended high-tech diagnosis and treatment with complementary and alternative medical interventions in a holistic, integrative approach to the care of US military personnel with the complex combination of TBI and psychological conditions, such as post-traumatic stress, depression, and anxiety. In this role, Dr. Kelly was frequently called upon by leaders of the Military Health System at the Pentagon, the US Congress, the Department of Veterans Affairs, and numerous military facilities in the continental US and abroad. Dr. Kelly has interacted with the FDA and clinical trials for brain injury throughout his esteemed career. He is a strong advocate for treatments in the acute phase of brain injury and understands the value of protecting the brain early on from inflammation, swelling and oxidative stress to gain better clinical outcomes. “We are fortunate to have such an esteemed neurologist as Dr. Kelly join our team in this important role at Oragenics. Dr. Kelly is recognized as a leading expert in concussion and other brain injuries and we are fortunate to have him lead our drug trials going forward. We are currently completing the drug manufacturing and formulation at GMP facilities to ensure the integrity of the drug before and during the trials, and we look forward to completing this work in the short-term and getting the Phase II trial underway,” stated Michael Redmond, President of Oragenics. In preclinical animal models, the drug has been shown to acutely improve molecular and behavioral outcomes following brain injury. In addition, intranasal delivery of the drug as a nanoparticle has been shown to enhance brain exposure and metabolism in animals. “Our Phase I human study has shown ONP-002 to be well tolerated in humans. Our mission now is to show that the ONP-002 brain protective mechanisms in animals translates to humans. Our Phase II study is designed to establish time to first dose, relationships between drug application and blood biomarkers, and the evaluation of clinical endpoints to determine improved in patient outcomes, ” said Dr. Kelly. Concussion is an unmet medical need. There is an estimated 69 million concussions annually reported worldwide. Common causes of concussion include falls, motor vehicle accidents, and contact sports. Other neurological disorders including Alzheimer’s Disease, Parkinson’s Disease and Chronic Traumatic Encephalopathy (CTE) have been linked to concussion. Post concussion syndrome is linked to long term disability and occurs in as high as 20% of concussed patients.

SARASOTA, Fla.--( BUSINESS WIRE )--Oragenics, Inc. (NYSE American: OGEN), a company focused on developing unique, intranasal pharmaceuticals for the treatment of neurological disorders, today announced it is preparing to undertake the final steps of GMP manufacturing and formulation of its drug candidate for its expected Phase IIA clinical trial. The drug candidate is expected to be combined with its novel intranasal device, for the treatment of mild Traumatic Brain Injury, aka concussion. Oragenics’ lead drug candidate, ONP-002, is a new chemical entity (NCE) designed to target the brain through self-propelled powdered delivery into the nasal cavity and onward to the brain. A 40-patient Phase I human study showed ONP-002 to be safe and well-tolerated. Oragenics is currently manufacturing the Active Pharmaceutical Ingredient (API) that will then be formulated and spray dried as a nanoparticle powder. Once formulated the powder is loaded into an intranasal device, believed to be novel, that is breath-propelled, which Oragenics believes will improve intranasal binding to the olfactory nerve beds for delivery directly to the brain. This application, believed to be novel, is designed as an acute field deliverable, intended to allow for concussed patients to get treatment in the early stages when the pathological cascade is most intense. Phase II patients will be recruited between the ages of 18-55 in the acute phase following concussion. Intranasal delivery of ONP-002 as a nanoparticle has been shown to enhance brain exposure and metabolism in animals. “ Preclinical intranasal targeting of the brain has been shown to improve outcomes in animals and safety margin following concussion. We are excited to be finishing up ONP-002 manufacturing and formulation work needed for our Phase II study which is on the horizon,” commented Michael Redmond, President of Oragenics. Concussion is an unmet medical need. There is an estimated 69M concussions annually reported worldwide. Common causes of concussion include falls, motor vehicle accidents, and contact sports. Other neurological disorders including Alzheimer’s Disease, Parkinson’s Disease and Chronic Traumatic Encephalopathy (CTE) have been linked to concussion. Post concussion syndrome is linked to long term disability and occurs in as high as 20% of concussed patients. “ Concussions can have serious long-term consequences. Manufacturing and formulating API in a GMP facility ensures the integrity of the drug before and during the trials, we look forward to completing this work in the short-term and getting the Phase II trial underway,” Greg Gironda, Oragenics Operational Consultant.

A 40-patient Phase I study showed ONP-002 to be safe and well-tolerated. Oragenics has begun the final process of synthesizing and formulating the drug needed for its Phase II clinical trial. It is expected that enrolled patients will be in the acute phase following concussions, after diagnosis the patient will quickly receive their first dose intranasally. “Concussion is a serious unmet medical need. An acute treatment that can mitigate the pathological cascade could help so many people. We are excited to get the Phase II clinical trials underway,” commented Dr. James “Jim” Kelly, Neurologist and Executive Director of the Marcus Institute of Brain Health and an advisor on the planned phase II trial. ONP-002 has been shown to have a neuroprotective molecular profile and improve behavioral outcomes including memory and motor performance in animal models of brain injury. The drug has a large safety margin between dosages used in the animal toxicology program and those used in the Phase I study and planned for the upcoming Phase II clinical trial. Intranasal delivery of ONP-002 as a nanoparticle has been shown to enhance brain exposure in animals. “Intranasal delivery targeting the brain is our model for improving brain health while maintaining a strong safety margin,” commented Michael Redmond, President of Oragenics. Concussion is an unmet medical need. There is an estimated 69M concussions annually reported worldwide. Common causes of concussion include falls, motor vehicle accidents and contact sports. Other neurological disorders including Alzheimer’s Disease, Parkinson’s Disease and Chronic Traumatic Encephalopathy (CTE) have been linked to concussion.
