Future Trends In RNAi Drug Delivery
By Dan Lukehart:For those interested in RNAi therapeutics, it would be wise to pay attention to every development related to delivery technology. The concept and clinical results behind RNAi are compelling, but perhaps something equally exciting is that there is still room to grow. With human proof of concept demonstrated, RNAi companies can reformulate with new delivery technology and enjoy the benefits. This article will examine next generation LNP delivery the pipeline.LNP technology for indications involved with the liver is the most mature delivery system within RNAi therapeutics. Current LNP (lipid nanoparticle) technology is in its 2nd generation (such as ALN-PCS, ALN-TTR02) which has ~100-fold increased potency and better safety than 1st generation (such as ALN-VSP, ALN-TTR1) offerings.One of the issues with the current 2nd generation LNP is that they have long elimination half-lives in plasma and tissues. It is suspected that they might accumulate over time and lead toComplete Story »
