US Patent update

 

Xenetic Biosciences plc (AIM: XEN.L), the bio-pharmaceutical company specialising in the development of high-value differentiated biologic drugs and vaccines, announces that it has received a notice of allowance of a patent application that covers the Company's co-delivery technology in the US. The application will proceed to grant shortly and Xenetic Biosciences will provide an update once the patent has been granted.

 

Xenetic Biosciences' co-delivery patent deals with a unique method of genetic immunisation. The method consists of packaging a protein vaccine together with a plasmid DNA that encodes the vaccine, in the same liposome and regardless of the liposome size. This ensures that both, the protein vaccine and the DNA encoding the vaccine are delivered simultaneously (co-delivery) in the same antigen presenting cells.

 

The patent provides protection for Xenetic Biosciences' co-delivery technology that is used in the Company's ImuXen product range. Xenetic Biosciences' ImuXen liposomal technology platform can be used to create and deliver DNA, protein based vaccines capable of generating enhanced immune responses.

 

Xenetic Biosciences already has Patents granted in relation to this technology in Europe, Russia and China as well as separate Patents that cover their polysaccharide based vaccines.
