Blue Water Biotech Announces Preclinical Data Supporting Immunogenicity of Novel Monkeypox Vaccine Utilizing Norovirus Virus-Like Particle Platform

CINCINNATI, Ohio, June 28, 2023 (GLOBE NEWSWIRE) — Blue Water Biotech, Inc. (“Blue Water” or the “Company”) (Nasdaq: BWV), a biotechnology and pharmaceutical company spanning multiple sectors, today announced preliminary preclinical data supporting the use of its norovirus shell and protrusion (“S&P”) virus-like particle (“VLP”) platform to develop a novel monkeypox vaccine candidate.

In August 2022, Blue Water announced plans to explore the development of its novel monkeypox vaccine candidate by presenting monkeypox antigens within the S&P platform. Following successful integration of selected antigens into the platform, mice were immunized with the vaccine candidate and analyzed for antibody levels in the blood. Initial data show that mice were able to generate an immune response following vaccination and antibodies were able to neutralize the vaccinia virus. Vaccinia, the virus responsible for smallpox disease, belongs to the same family as monkeypox virus and has shown high levels of cross-reactivity with monkeypox.

“We are thrilled to announce this exciting initial step in development of our monkeypox vaccine candidate,” said Joseph Hernandez, Chairman and Chief Executive Officer of Blue Water. “This platform has shown wide versatility across multiple infectious diseases, including influenza, norovirus, rotavirus, among others, and we are excited to continue to work towards a next generation monkeypox vaccine. While we are heavily focused on the commercialization of our recently acquired FDA approved assets, our development programs continue with success, highlighted by this new data.”

“This data is certainly promising for future development of this VLP vaccine candidate,” said Ali Fattom, Ph.D., Head of Science and Discovery of Blue Water. “Current vaccines utilize the entire vaccinia virus, while our approach selects targeted antigens hypothesized to generate robust immune responses and by partnering this with our VLP platform, we believe we will be able to create a novel, effective vaccine to protect individuals around the world. Armed with information from this preliminary study, we can confidently move forward in preclinical development and initiate studies to show protective immunity in relevant animal models, with the ultimate goal of bringing this candidate to clinical trials and commercialization.”

In July 2021, Blue Water entered an exclusive, global licensing agreement with Cincinnati Children’s Hospital Medical Center to develop vaccines for multiple infectious diseases utilizing the latter’s novel VLP vaccine platform. The platform leverages norovirus capsid proteins to present foreign antigens for immune enhancement.

According to the World Health Organization, monkeypox is a virus transmitted to humans from animals, with clinical symptoms like those seen in smallpox patients. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. According to the Centers for Disease Control and Prevention (“CDC”), the 2022 outbreak of monkeypox resulted in over 88,000 cases across 111 locations, and in May 2023, the CDC reported a potential risk for 12 confirmed monkeypox cases in the Chicago area. There are two vaccines approved for prevention of monkeypox disease in the United States, but limited availability of either vaccine resulted in increasing cases within the United States and globally during the 2022 outbreak.
