DELIVERY PLATFORMS

SAMiRNA® (Self-Assembled-Micelle Inhibitory RNA)


SAMiRNA® is made of DNA/RNA heteroduplex siRNA core with conjugated hydrophilic four Hexaethylene glycol (HEG) and hydrophobic hydrocarbon tails at each end, which forms spontaneously a spherical and neutral nanoparticle in the aqueous solution.

SAMiRNA represents a significant advancement in siRNA-based therapeutics, addressing many common challenges associated with this drug class.

siRNA drugs offer high target specificity and the ability to silence virtually any gene. They are easier to design than small molecules, allow flexible routes of administration, have low dosing frequency, and can provide sustained effects with manageable safety profiles.

However, conventional siRNAs are often unstable in vivo, prone to nuclease degradation, and can activate innate immune responses. Off-target effects and toxicity remain major barriers.


SAMiRNA addresses these limitations through optimized sequence design and a proprietary delivery platform.

The self-assembled micelle structure protects the siRNA from degradation while facilitating cellular uptake. Notably, off-target analysis confirmed that SAMiRNA does not induce off-target gene expression changes.

SAMiRNA® is the Next Generation siRNA Therapeutics!
