First definitive demonstration of nitric oxide efficacy against the SARS-CoV-2 virus
Research Triangle Park, N.C. (September 10, 2020) – KNOW Bio, LLC has generated the first definitive evidence that nitric oxide (NO) can inhibit viral reproduction of SARS-CoV-2, the human coronavirus that causes COVID-19. Nitric oxide is a molecule produced naturally by the body to regulate blood flow, control inflammation, and defend against invading microorganisms.
These milestone in-vitro experiments were conducted by testing multiple nitric oxide-releasing compounds against wild type SARS-CoV-2 virus at an independent laboratory with a deep history of antiviral research. Therapeutic doses (<200 µM) were applied to infected VERO E6 cells and showed a dose-dependent effect on viral replication. The result was a greater than 99.9% reduction in virus observed after 24 hours versus virus observed on untreated cells.
Furthermore, there was no cytotoxic impact (cell damage or cell death) on uninfected cells. “We are the first to confirm the potent biological activity of nitric oxide against SARS-CoV-2, the novel coronavirus that causes COVID-19,” said Neal Hunter, Chief Executive Officer, KNOW Bio, LLC. “As a leader in the development of NO-based therapies, we felt we were best positioned to establish that NO is effective against this virus.”
Previous reports have only speculated on the potential of nitric oxide to serve as a therapeutic for patients with COVID-19 or as a preventative countermeasure for those who are at risk of exposure to the virus.1 These conjectures were based in large part on prior published scientific evidence derived from studies conducted on the original SARS-CoV virus.
“The expansive literature supporting nitric oxide’s function as a broad-spectrum antimicrobial, shows that nitric oxide-based approaches can play a role in preventing, limiting, and/or treating the pulmonary consequences of COVID-19,” said Mark Schoenfisch, Ph.D., Chief Scientific Officer, KNOW Bio, LLC.
Nitric Oxide (NO) has been reported to:
“We have gained new understandings into the effective concentrations, rates of release and mechanism of action of nitric oxide against human coronavirus - providing valuable insights into safety and efficacy,” continued Schoenfisch.
Submission for publication and peer review is expected before year end. “There are millions of lives being disrupted and hundreds of thousands lost to this frightening virus,” Hunter continued. “Our findings clearly show that nitric oxide-based therapeutics must be a part of any well-thought response to the COVID-19 pandemic.” About KNOW Bio, LLC KNOW Bio, LLC is a life science incubator focused on using its extensive intellectual property portfolio in the field of nitric oxide to redefine the standard of care for a number of diseases and conditions.

DURHAM, N.C., Oct. 22, 2019 -- Vast Therapeutics, Inc., a subsidiary of KNOW Bio, LLC, announces that BIOC11 eradicated 99% of the Nontuberculous Mycobacteria (NTM) in an in vivo animal model of infection; this data will be presented at the National Cystic Fibrosis Conference to be held in Nashville, Tennessee from October 31 to November 2, 2019. The NTM animal model is broadly recognized by the field as predictive for evaluating efficacy in humans. Dr. Diane Ordway, whose laboratory at Colorado State University developed the model and conducted the study, noted "To achieve this level of efficacy is impressive, and to do so without any observed negative effects on the animals is particularly exciting." "BIOC11 is an important expansion of our pipeline as it looks and acts more like a small molecule drug candidate rather than the larger biopolymers that we have shown efficacy with in the past," said Dr. Mark Schoenfisch, President and CSO of Vast Therapeutics. "Not only did we achieve 99% reduction in NTM counts, the activity was superior to traditional antibiotics, validating our belief in the superiority of our technology over traditional antibiotic treatments being used today. We are equally excited that the use of our drug candidate led to no adverse effects. Our proprietary water-soluble NO-releasing biopolymer technology, which delivers NO safely and at bactericidal levels for extended periods, reflects an advanced platform for the delivery of nitric oxide. The antibacterial activity of BIOC11 in this animal model of infection was similar to that of our other drug candidate, BIOC51, demonstrating that our nitric oxide-releasing biopolymer pipeline is deep with additional candidates. We look forward to progressing our development toward first-in-human clinical trials." In vitro, BIOC11 has eradicated every bacterial pathogen tested to date, including 25 species of both Gram-positive and Gram-negative bacteria, 21 distinct strains of Pseudomonas aeruginosa, and 35 antibiotic-resistant strains deemed superbugs by the Center of Disease Control and World Health Organization because of their severe threat to public health. Additionally, given the relationship between NTM and Tuberculosis, and the track record of these compounds in eradicating bacterial pathogens, the Company believes these compounds will also be effective against Tuberculosis. "Another drug candidate testing to this level of efficacy provides further evidence that Vast Therapeutics and KNOW Bio are at the forefront of antimicrobial technology," said Neal Hunter, CEO and Chairman of the Board of Vast Therapeutics and Managing Director of KNOW Bio, LLC. "With the CDC and WHO stating these types of infections are the most severe risk to our world, our materials systems will be a major factor in combatting this threat. Rapidly getting these products to patients of need is our focus and we've added considerable resources to make this happen.
