The current solutions have advanced to the point that RNA therapeutics are now a reality,
BUT significant improvement and innovation are needed to ensure the availability and accessibility of RNA therapeutics for a wider range of applications.
Our BIO-COURIER technology builds upon lipid nanoparticle technology to optimize and stabilise it through next-generation silicon stabilized hybrid Lipid Nanoparticles (sshLNP).
Silicon’s positive charge and high ζ-potential electrostatically binds and condenses RNA preventing the premature disassociation of RNA and reducing the reliance on cationic lipids.
Surface lipids combined with pH dependant silicon/RNA bond dissolution maximise transfection efficiency
High volumes of tightly condensed RNA are electrostatically bonded to the silicon matrix, protecting them from hydrolysis to prolong their systemic survival
Versatility of particle size, surface charge and the addition of surface ligands enables passive or active cell targeting and multiple administration routes
The structural integrity of the Silicon metalloid prevents physical collapse of the particle permitting lyophilisation whilst retaining RNA integrity
Surface lipids and amino acids control the rate of silicon hydrolysis to only produce 100% bioabsorbable Ortho silicic acid (OSA) an essential micromineral
BIO-COURIERS are biologically friendly, the components are U.S. FDA generally recognized as safe (GRAS) materials and are fully biocompatible and bioabsorbable obviating carrier-related toxicity. sshLNP and PROSILIC®, our lead BIO-COURIERs are 100% bioabsorbable as they fully dissipate to Ortho-Silicic Acid (OSA), the bioavailable form of silicon and essential micromineral for cellular health.
Before the COVID-19 pandemic, the storage temperature of mRNA vaccine candidates in development had not been given much attention. Typically, small batches were kept frozen at -80 oC, and then thawed and administered as needed.
Now storage, transport, and delivery under ultracold conditions have created a huge challenge with hundreds of millions (eventually billions) of doses being administered all around the world.
COLHYSILCTM embeds RNA + silicon stabilized hybrid Lipid Nanoparticles (sshLNP) in hydrogel to create a system that allows long-term storage of RNA therapeutics at ambient temperatures.
The formulation is also suitable for direct administration and large-scale manufacturing.
