Chronic Traumatic Encephalopathy

Calgary, Alberta--(News - March 25, 2024) - Marvel Biosciences Corp. (TSXV: MRVL) (OTCQB: MBCOF), and its wholly owned subsidiary, Marvel Biotechnology Inc. (collectively the "Company" or "Marvel"), today reported promising interim results from its acute study on MB-204 conducted by Professor Emmanuel Planel of Laval University, a world expert on Tau pathology. Tau phosphorylation is a process where phosphates attach to a Tau protein in the brain. When Tau proteins become overly phosphorylated, they aggregate and form "tangles" in neurons. The study demonstrated that short term oral dosing of MB-204 reduces Tau phosphorylation at key positions in Tau. Abnormal Tau phosphorylation is a key feature of cognitive impairment and neurodegenerative diseases like Alzheimer's disease. Using a mouse model of Tau hyperphosphorylation, pioneered by Dr. Planel, a 2.5 mg/kg oral dose of MB-204 significantly reduced Tau phosphorylation at multiple epitopes in the cortex of mice, including the AT8 site on Tau. The AT8 site is of particular interest because it is used clinically to assess the extent of Tau tangles (Braak staging) and is well correlated with the degree of cognitive impairment. "These are very promising preliminary results with MB-204," commented Dr. Planel, "considering that hyperphosphorylated Tau is present not only in Alzheimer's but also in other neurodegenerative diseases such as Parkinson's, Chronic Traumatic Encephalopathy, FTD, CBD, PSP etc., it has the potential to be effective for multiple pathologies." "We are grateful for the opportunity to conduct this study with Dr. Planel," commented Dr. Mark Williams, CSO of Marvel Biosciences. "The A2a receptor has emerged as a target for depression, autism and Alzheimer's disease. We believe the accumulating data on MB-204 in each of these models suggests a promising product pro look forward to starting clinical testing shortly." About Marvel Biosciences Corp. Marvel Biosciences Corp., and its wholly owned subsidiary, Marvel Biotechnology Inc., is a Calgary-based pre-clinical stage pharmaceutical development biotechnology company that utilizes a "drug redevelopment" approach to drug development. Historically, when a new class of drug is developed, it is optimized for a particular target, but typically only approved for a specific disease. Often, a new disease is identified which involves the same target, however, pending the remaining patent life, the originally approved drug may not have sufficient time left for it to be commercially viable to be developed for the new disease indication. Marvel develops new synthetic chemical derivatives of the original approved drug for the new disease indication. Patent protection is sought, as the new potential asset is developed by the Company. The Company believes the business model results in significantly less risk, cost and time to develop its assets compared to traditional biotechnology companies. Marvel Biotechnology Inc. has currently developed several new chemical entities, using synthetic chemical derivatives of known, off-patent drugs, that inhibit the A2a adenosine receptor with application to neurological diseases (depression & anxiety, Alzheimer's, ADHD), and the non-neurological conditions of cancer and non-alcoholic steatohepatitis. Marvel is also exploring additional undisclosed targets to expand its asset pipeline. Contact Information Marvel Biosciences Corp. J.

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.

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.
