Pilot study reveals early evidence of efficacy of a pharmacologic treatment for concussion, as patients experienced faster symptom reduction and return to physical activity PHILADELPHIA, March 19, 2024 /PRNewswire/ -- In the first clinical trial of a targeted pharmacologic therapeutic for mild traumatic brain injury in pediatric patients, scientists from the Minds Matter Concussion Frontier Program at Children's Hospital of Philadelphia (CHOP) have found preliminary evidence that adolescents and young adults with concussion who take a specific formulation of branched chain amino acid (BCAA) supplements after injury experience faster symptom reduction and return to physical activity. The findings were published online by the Journal of Neurotrauma. More than 2 million concussions occur in the youth and adolescent population in the United States each year. The mainstay of treatment remains symptom management with temporary modification of cognitive and physical activity and over the counter medication. Although active rehabilitation strategies have shown promise for improving recovery time, including aerobic, vestibular, and vision interventions, these can be time and labor intensive. To date, no targeted pharmacologic intervention to improve clinical outcomes in concussion has been evaluated in humans. Animal model studies of mild to moderate traumatic brain injury, which have been led by the study's senior author, Akiva S. Cohen, PhD, Professor of Neuroscience in the Department of Anesthesiology and Critical Care Medicine at CHOP and a research professor of Anesthesiology and Critical Care at the Perelman School of Medicine of the University of Pennsylvania, have shown that supplementation with a specific formulation of three BCAAs – leucine, isoleucine and valine – improve neurocognitive function. However, prior to this study, no human studies involving adolescents and young adults have assessed the potential benefits of this formulation of BCAAs as a specific treatment to aid in concussion recovery. "The goal of this pilot study was to determine, among several different doses, whether our specific formulation of BCAAs could accelerate recovery – faster reduction in symptoms and return to baseline physical activity," Cohen said. "Based on our work in animal models, we expected that our specific formulation of BCAA supplementation would result in a more rapid resolution in symptom burden and improved physical activity levels which are key measures of recovery from a concussion." The scientists conducted a pilot, double-blind, randomized controlled trial of participants between the ages of 12-30 years who presented with concussion to outpatient clinics, urgent care and emergency departments across the CHOP Network between June of 2014 and December of 2020. Individual participants were divided into five groups consisting of a placebo arm and different treatment arms of 15 g, 30 g, 45 g and 54 g doses of a specific formulation of BCAAs. The participants were followed for a period of 21 days after enrollment. Participants were assessed with daily computerized neurocognitive tests, reported symptom score, physical and cognitive activity, treatment compliance and adverse events. A total of 38 participants had analyzable data after study completion. The study found that there was a significant reduction in and faster resolution of the total symptom score in a dose-dependent fashion with the specific formulation of BCAA supplementation, with a significant decrease in total symptoms across the study; for every 500 g of the treatment consumed, the total symptom score, on a scale of 0-54 (with 0 representing no symptoms), dropped 4 points. Similar significant improvements were seen in a faster return to physical activity, with an increase of 0.5 on a 0-5 scale of physical activity for each 500 g of the defined BCAA supplement consumed. The treatment was very well tolerated; no serious adverse events were reported in the study, and there were no differences in mild adverse events between the placebo and treatment groups. "Our results demonstrate that our specific formulation of BCAA supplementation is a highly promising treatment that addresses the underlying mechanism driving concussion symptoms in order to accelerate recovery and improve outcomes," said the study's first author Daniel Corwin, MD, MSCE, Assistant Professor of Pediatrics and Emergency Department Lead of the Minds Matter Concussion Frontier Program at CHOP. "While a larger study is needed to confirm the formulation's efficacy before routine use of BCAA supplementation should be recommended, we are extremely encouraged by these preliminary findings, the first trial to demonstrate that a targeted pharmacologic using a specific formulation of BCAAs may be useful as a treatment for youth and young adult concussion."

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.

(1) Non-International Financial Reporting Standard (“IFRS”) and Other Financial Measures defined by the Company below. Q4 2023 Financial Results Total Revenue Total revenue is comprised of clinic revenue and non-clinic revenue. Total revenue was $16.8 million for the three months ended December 31, 2023 compared to $16.1 million for the three months ended December 31, 2022. Total revenue was $66.1 million for the year ended December 31, 2023 compared to $62.7 million for the year ended December 31, 2022. Clinic Revenue Clinic revenue is generated through the provision of medical services to patients. Clinic revenue was $15.3 million for the three months ended December 31, 2023 compared to $15.0 million for the three months ended December 31, 2022. Clinic revenue was $61.0 million for the year ended December 31, 2023 compared to $58.7 million for the year ended December 31, 2022. The increase in clinic revenue for the year ended December 31, 2023 was primarily due to stronger revenues from fluoroscopy and existing medical clinics. Non-clinic Revenue Non-clinic revenue was $1.5 million for the three months ended December 31, 2023 compared to $1.1 million for the three months ended December 31, 2022. Non-clinic revenue was $5.1 million for the year ended December 31, 2023 compared to $4.0 million for the year ended December 31, 2022. Non-clinic revenue is earned from physician staffing allocation services where the Company provides physicians for provincial and federal correctional institutions across Canada, and from contract research services provided to pharmaceutical companies and clinical research organizations. This revenue fluctuates depending on the need for physicians in certain institutions and the timing and enrolment of clinical studies that the Company is working on. Gross margin % was 19.2% for the three months ended December 31, 2023 compared to 17.5% for the three months ended December 31, 2022. Gross margin % was 18.6% for the year ended December 31, 2023 compared to 17.3% for the year ended December 31, 2022. Gross margin for the comparative year was impacted by remuneration payment accruals due to the HealthPointe acquisition resulting in increased cost of medical services of $0.8 million. Excluding these transaction-related accruals, gross margin % would have been 18.7% and 18.5% for the three months and year ended December 31, 2022. (see Non-IFRS Financial Measures - Gross Margin, Gross Margin %, Adjusted Gross Margin and Adjusted Gross Margin % ) . Adjusted EBITDA was $0.8 million and $3.2 million for the three months and year ended December 31, 2023 compared to $0.8 million and $2.3 million for the three months and year ended December 31, 2022. Liquidity and Capital Resources As at December 31, 2023, the Company’s net debt was $2.9 million, compared to $5.3 million as at December 31, 2022. The Company’s net debt as at December 31, 2023 consisted of $3.2 million of cash and cash equivalents and long-term debt of $6.1 million compared to $1.5 million of cash and cash equivalents and long-term debt of $6.8 million as at December 31, 2022. Non-IFRS Financial and Other Measures The Company discloses non-IFRS measures (such as EBITDA, adjusted EBITDA, gross margin and adjusted gross margin) and non-IFRS ratios (such as gross margin % and adjusted gross margin %) that do not have standardized meanings prescribed by International Financial Reporting Standards (“IFRS”). The Company believes that shareholders, investment analysts and other readers find such measures helpful in understanding the Company’s financial performance. Non-IFRS financial measures and other measures do not have any standardized meaning prescribed by IFRS and may not have been calculated in the same way as similarly named financial measures presented by other reporting issuers and therefore unlikely to be comparable to similar measures presented by other companies. Furthermore, these non-IFRS measures and other measures should not be considered in isolation or as a substitute for measures of performance or cash flows as prepared in accordance with IFRS. These measures should be considered as supplemental in nature and not as a substitute for related financial information prepared in accordance with IFRS. EBITDA and Adjusted EBITDA EBITDA refers to net income (loss) determined in accordance with IFRS, before depreciation and amortization, net interest expense (income) and income tax expense (recovery). The Company defines adjusted EBITDA, as EBITDA, excluding stock-based compensation expense, restructuring costs, gain on derecognition of other obligations, fair value adjustments, transaction costs, impairment charges, gain on sale of building, government loan forgiveness and finance income. Management believes EBITDA and adjusted EBITDA are useful supplemental non-GAAP measures to determine the Company’s ability to generate cash available for operations, working capital, capital expenditures, debt repayments, interest expense and income taxes. The following table provides a reconciliation of net and comprehensive income (loss) to EBITDA and adjusted EBITDA: Three months ended December 31 Year ended December 31 2023 2022 2023 2022 (in thousands) $ $ $ $ Net and comprehensive loss (368 ) (1,860 ) (191 ) (4,275 ) Add back: Depreciation and amortization 738 669 2,603 2,665 Interest cost 267 214 928 832 Income tax expense (13 ) 29 246 194 EBITDA 624 (948 ) 3,586 (584 ) Add back: Stock-based compensation 44 53 183 98 Transaction costs (1) 134 202 226 808 Finance income (1 ) (4 ) (9 ) (22 ) Restructuring - 67 - 519 Gain on sale of building - - (758 ) - Gain on government loans (40 ) - (40 ) - Gain on derecognition of other obligations - (500 ) - (500 ) Impairment - 1,938 - 1,938 Adjusted EBITDA 761 808 3,188 2,257 Attributed to: Shareholders of NeuPath Health Inc. 740 829 3,190 2,350 Non-controlling interest 21 (21 ) (2 ) (93 ) 761 808 3,188 2,257 (1) For the year ended December 31, 2022, $750 of accrued contingent consideration that under IFRS 3, Business Combinations (“IFRS 3”) was not permitted to be included in the acquisition cost has been accounted for as remuneration rather than consideration transferred. Gross Margin, Gross Margin %, Adjusted Gross Margin and Adjusted Gross Margin % Management believes gross margin, gross margin %, adjusted gross margin and adjusted gross margin % are important supplemental non-GAAP measures for evaluating operating performance and to allow for operating performance comparability from period-to-period. Gross margin is calculated as total revenue minus COMS. Gross margin % is calculated as gross margin divided by total revenue. Adjusted gross margin is calculated as gross margin, plus remuneration payment accruals related to the HealthPointe acquisition. Adjusted gross margin % is calculated as adjusted gross margin divided by total revenue. The following table provides a reconciliation of total revenue to gross margin and adjusted gross margin: Year ended December 31, 2023 Year ended December 31, 2022 (in thousands, except for %s) $ $ Clinic revenue 60,988 58,702 Non-clinic revenue 5,114 3,951 Total revenue 66,102 62,653 Cost of medical services 53,805 51,834 Gross margin (1) 12,297 10,819 Gross margin % (1) 18.6% 17.3% Add back: HealthPointe remuneration payment accruals (2) - 750 Adjusted gross margin (1) 12,297 11,569 Adjusted gross margin % (1) 18.6% 18.5% (1) Gross margin, gross margin %, adjusted gross margin and adjusted gross margin % are non-IFRS measures.
