A history of enabling drug delivery research

For over 30 years, Avanti has been working with the pharmaceutical and diagnostic industry to provide solutions that improve lives. We were integrally involved in the development of liposomal-based drug delivery systems and over the past decade we have concentrated on developing lipid components used in Lipid Nanoparticle (LNP) delivery technologies.

Lipid Nanoparticle (LNP) delivery technology

LNPs are lipid-based drug delivery systems that carry nucleic acid material. These systems primarily rely on four lipid components: a PEG lipid, amino (cationic) lipid, structural lipid, and cholesterol.  

The ionizable cationic lipids are used to sequester the genetic material through a charge interaction. This is encapsulated by the structural lipid and functionalised on the exterior with PEG lipids. Genetic material is highly susceptible to RNAse activity but the LNP protects the genetic material from degradation. The LNP also allows the genetic material to gain access to the cell and once inside, to be released.  This allows the cellular machinery to translate the delivered genetic material into a cellular response.
