• Companies jointly submitted a $750,000 USD application to BARDA to use Prepaire™ Shield discovery platform to assess repurposed drugs combined with onternabez as Chemical Threat Medical Countermeasures.
  
  
• Partnership leverages respective expertise, technology, and capabilities to identify new combination therapies and improve clinical trajectories of patients exposed to pulmonary and nerve chemical agents.

OTTAWA, ON, Oct. 11, 2022 /PRNewswire/ - Tetra Bio-Pharma Inc. ("Tetra" or the "Company") (TSX: TBP) (OTCQB: TBPMF) (FRA: JAM1), a leader in cannabinoid-derived drug discovery and development announced today it has successfully submitted, in collaboration with Prepaire, a grant application to the Office of Biomedical Advanced Research and Development Authority (BARDA), Division of Research, Innovation and Ventures (DRIVe).

The project aims at improving the management of patients exposed to pulmonary (i.e., chlorine, phosphogene) or nerve chemical agents (i.e., Sarin, Soman, or Tabun) and optimize their clinical trajectories to minimize the outcome following mass casualty events.

Tetra and Prepaire will combine their respective expertise and capabilities to reinvent the drug development process through a fast, innovative, and cost-effective approach using the Prepaire™ Shield discovery platform and Tetra's proprietary compound, onternabez. Prepaire™ Shield is an integrated multi-modal/level data solution encompassing state-of-the-art Artificial Intelligence (AI) to generate new potential combination treatments with in vitro validation testing using induced pluripotent stem cells (IPSC) and a retrosynthesis tool to help develop a comprehensive Clinical Decision Support system. Newly identified therapies will include repurposed drugs combined with Tetra's investigational compound, onternabez, to treat acute and long-term effects of pulmonary and nerve Chemical War Agents (CWAs). Onternabez is a selective activator of the cannabinoid type 2 receptor (CB2R), which is part of the body's endocannabinoid system and an important target for homeostatic regulation of the Central Nervous System and the Immune System. Pre-clinical efficacy studies have shown that onternabez has anti-inflammatory and anti-fibrotic properties, decreasing pulmonary and systemic inflammation and ARDS-related drug damage. Additionally, onternabez exhibits neuro-anti-inflammatory and neuroprotectant activities in response to pathophysiological brain insults. Therefore, the management of patients who have been exposed to a pulmonary CWA can significantly benefit from combination treatments that address the acute hyperinflammation/CRS and potential downstream pulmonary fibrosis. Additionally, patients exposed to nerve chemical agents could benefit from the new drug synthesis models for developing AChE (acetylcholine esterase) reactivators to be administered together with an anti-inflammatory and neuroprotectant agent to prevent long-term neuro-deficiency.

Carl Freer, Founder and Chief Innovation Officer at Prepaire, stated "We are excited by the opportunity for Prepaire and Tetra to be considered to partner with BARDA to identify medical countermeasures to managing patients who have been exposed to a pulmonary CWA and can significantly benefit from combination treatments that address this acute hyperinflammation/CRS and potential downstream pulmonary fibrosis. Patients could benefit from the new drug synthesis models for developing AChE reactivators to be administered with an anti-inflammatory and neuroprotectant agent to prevent long-term neuro-deficiency. Prepaire Shield is designed to accelerate the pace of discovery and innovation, including its vast data sets and advanced analytics, enabling faster evidence-based decision-making. These efforts will unlock hidden insights and provide new and unique perspectives using intelligence in previously unavailable ways to analyze relevant therapeutics."

Guy Chamberland, CEO, and CRO at Tetra commented "CWA attacks substantially increased over the last decade in certain regions of the globe, but the treatment of civilian populations stayed the same over the last 50 years and is mainly about advanced life support. Prepaire's disruptive technology, Prepaire Shield, together with our onternabez compound, has the potential to unveil new combination treatments to improve the management of choking and nerve agent victims. I'm excited by this innovative drug discovery approach and the opportunity in front of us."

Onternabez, the active substance of ARDS-003, a novel First in Human (FIH) drug product, is a potent and selective full agonist of the type 2 cannabinoid receptor (CB2R), an important immunomodulatory target. ARDS-003 is positioned to modulate acute systemic inflammation and prevent Sepsis, acute respiratory distress syndrome (ARDS) and organ damage - ARDS represents the severe end of lung dysfunction resulting from systemic inflammation secondary to infectious or non-infectious clinical insult (McIntosh, 2020).  While the clinical profile of ARDS arising from viral (COVID) or bacterial sepsis can vary, hyperinflammation involving a dysfunctional immune response is a common mediator of lung damage. Tetra's pre-clinical studies have demonstrated that ARDS-003 decreases this hyperinflammatory response and slows disease progression. Additionally, pre-clinical efficacy studies have shown that onternabez-induced CB2R activation dampens the pro-inflammatory behavior of microglia, decreasing the expression of neuronal pro-inflammatory cytokines and the release of nitric oxide, ultimately reducing secondary damage to the neurons in the central nervous system.

Tetra Bio-Pharma (TSX: TBP) (OTCQB: TBPMF) (FRA:JAM1) is a leader in cannabinoid-derived drug discovery and development with a FDA and a Health Canada cleared clinical program aimed at bringing novel prescription drugs and treatments to patients and their healthcare providers. Their evidence-based scientific approach has enabled them to develop a pipeline of cannabinoid-based drug products for a range of medical conditions, including pain, inflammation, and oncology. With patients at the core of what they do, Tetra Bio-Pharma is focused on providing rigorous scientific validation and safety data required for inclusion into the existing biopharma industry by regulators, physicians and insurance companies.
