Aphios Receives U.S. Patent Allowance for Room Temperature-Stable Single-Shot mRNA COVID-19 Vaccine
核心洞察
Aphios Corporation (搜索) received U.S. Patent and Trademark Office allowance for a novel COVID-19 (搜索) vaccine platform that remains stable at room temperature, eliminating ultra-cold storage requirements.
The patented technology uses a proprietary double nanoencapsulation system that embeds mRNA in lipid nanoparticles and coats them with biodegradable polymer nanospheres for extended release.
The single-dose, PEG-free vaccine addresses current mRNA vaccine limitations including storage constraints, multiple dosing requirements, and hypersensitivity concerns.
Aphios Corporation (搜索) announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for its patent application (Application No. 17/699,359), titled "Room Temperature-Stable, Single-Shot mRNA Vaccine for COVID-19 (搜索)." This milestone validates the company's innovative approach to addressing critical limitations of current mRNA vaccine technologies.
Revolutionary Double Nanoencapsulation System
The newly allowed patent covers a next-generation COVID-19 (搜索) vaccine platform utilizing a proprietary double nanoencapsulation system. This technology first embeds mRNA molecules encoding the SARS-CoV-2 (搜索) spike protein (搜索) in Lipid Nanoparticles (LPN) or Phospholipid Nanosomes, then coats them with biodegradable polymer nanospheres using Aphios' green SuperFluids™ technology. This novel method enables extended release of the mRNA and allows the vaccine to remain stable at room or refrigerator temperature, eliminating the need for ultra-cold storage and complex distribution infrastructure.
Addressing Current mRNA Vaccine Limitations
Current mRNA vaccines, while highly effective, face significant constraints including storage requirements of -70°C or -20°C, multiple doses, and PEG-related hypersensitivity concerns. Aphios' patented solution directly addresses these issues by offering a PEG-free, single-dose vaccine with sustained antigen release and broad scalability for global deployment.
"This patent marks a major step forward in Aphios' mission to make vaccines more accessible, practical, and safer for people worldwide," said Dr. Trevor P. Castor, Founder and CEO of Aphios. "By eliminating cold chain barriers and reducing the need for boosters, we're positioning this technology to serve not only in the fight against COVID-19 (搜索) but also in preparation for future pandemics."
Broader Applications and Manufacturing Advantages
The invention has broader applicability for other viral infectious diseases, particularly in regions lacking advanced medical infrastructure. The continuous-flow, solvent-free encapsulation process ensures a high level of safety, environmental sustainability, and manufacturability.
With this patent allowance, Aphios is actively preparing for further development and regulatory advancement while exploring strategic partnerships for clinical trials, manufacturing, and global distribution. The company is an emerging growth biotechnology firm developing green enabling technology platforms to improve drug discovery and manufacturing, nanotechnology drug delivery, and pathogenic safety.
