ADELAIDE, AUS, Jul 9, 2021 – (ACN Newswire via SEAPRWire.com) – The largest Australian full-service CRO for international biotechs and Frost & Sullivan Asia-Pacific CRO Market Leadership Award winner Avance Clinical today congratulated client Tetherex Pharmaceuticals on first patient dosing for its Phase 1 vaccine clinical trial.
Tetherex Pharmaceuticals, Inc. is a privately held, clinical stage biopharmaceutical company focused on development of selectin inhibitor therapeutics for the treatment of a broad range of inflammatory diseases and single-cycle adenovirus vaccines for multiple infectious diseases and cancer indications.
Avance Clinical Chief Scientific Officer Dr Gabriel Kremmidiotis said:
“The exciting aspect of the Tetherex product is the potential to vaccinate using a nasal spray. Administering the vaccine via the same route that the virus uses to get into our bodies, may result in more effective protection compared to the first generation Covid-19 vaccine products currently being administered as injectables. Commencement of dosing with the Tetherex Covid-19 vaccine product constitutes a major achievement for the Avance Clinical team who played a key role in supporting Tetherex in gaining regulatory approval to conduct the First-in-Human trial with their exciting vaccine candidate.”
According to Tetherex Pharmaceutical’s announcement:
Tetherex Pharmaceuticals has executed an exclusive worldwide license with Mayo Clinic for the development and commercialization of a novel single-cycle adenovirus vaccine platform. The platform will be used to target multiple infectious diseases, beginning with a Phase 1 clinical study investigating a vaccine for COVID-19. Dosing of the initial cohort of the Phase 1 study is underway in Australia.
“Current adenovirus vaccines under investigation for COVID-19 and other infectious diseases are highly restricted in the amount of vaccine antigen they can deliver to cells,” said Dr. Russell Rother, President and Chief Operating Officer of Tetherex. “The single-cycle adenovirus platform allows one round of robust vaccine antigen expression to occur without the generation of infectious virus particles which, in preclinical models, translates to a marked improvement in the ensuing immune response.”
About the Single Cycle Adenovirus Vaccine Platform
The single-cycle adenovirus platform was developed to enhance the expression of target antigens, amplifying immune responses to infectious disease targets. Preclinical studies have demonstrated that the single-cycle adenovirus can increase target antigen expression up to 100-fold over currently utilized replication defective adenovirus vaccines. Intranasal administration of single-cycle vaccine elicits both systemic and mucosal immune responses. A mucosal response allows the immune system to encounter respiratory viruses like SARS-CoV-2 at the site of entry while the viral titers are lower. The platform also provides a robust manufacturing and supply chain paradigm relative to other vaccine platforms, such as mRNA.
Tetherex’s Phase 1 open label study, designed to assess safety, reactogenicity and immunogenicity of the single-cycle adenovirus vaccine, is expected to recruit a total of approximately 80 healthy volunteers and includes both a single ascending dose group and a multiple dose group. Subjects will receive the vaccine via either intramuscular or intranasal administration.
The study site is Nucleus Network in Brisbane, and Dr Paul Griffin Nucleus Network’s Principal Investigator said:
“The covid 19 global pandemic continues to impact lives around the world. We are very fortunate to have developed a number of vaccines for Covid-19 already that are safe and highly effective. These vaccines are beginning to give us the capacity to start to reduce the impact of this viral infection, however it’s clear there are certain properties of these vaccines that we would ideally like to improve upon such as having a vaccine that could be given via a route other than needle and syringe and perhaps a vaccine that could further reduce the ability for a vaccinated individual to become infected in the first place, a so called transmission blocking vaccine. A vaccine given intranasally has the potential to achieve some of these objects hence I am very excited to be the principal Investigator on the Tetherex clinical trial.”
“The addition of this novel vaccine platform to the Tetherex portfolio significantly expands our ability to leverage our scientific and clinical development expertise and broadens our overall technology base. This reduces risk to our investors while providing the potential of significant upside,” said Dr. Scott Rollins, Chairman and Chief Executive Officer of Tetherex. “The platform will be utilized to target multiple infectious diseases which allows Tetherex to seek partnerships and alliances for the ever-expanding infectious disease marketplace.”
