RXi Pharmaceuticals Presents Self-Delivering RNAi Data at Scar Club Meeting in France

 

Dr. Pavco’s presentation describes new preclinical data exemplifying the performance of RXi’s proprietary self-delivering rxRNA (sd-rxRNA™) compounds in an in vivo model of compromised skin. Data generated using a fluorescently-tagged sd-rxRNA™ compound demonstrate spontaneous cellular uptake into dermal cells and a significant, sustained and reproducible silencing of the targeted mRNA. The data presented establish the efficacy of locally-administered sd-rxRNA™ in animal models and support the potential use of these novel compounds for clinical applications where direct or local administration is possible.

"We are very encouraged with the substantial progress we have made with our therapeutic platform, especially our proprietary sd-rxRNA™,” said Noah D. Beerman, President and Chief Executive Officer of RXi. “Delivery remains one of the most important objectives in our efforts to advance RNAi therapeutics into patients. Our demonstration that sd-rxRNA™ compounds efficiently enter cells in vivo and effect significant gene silencing without the need for an additional delivery vehicle is an important advancement for RXi in its progression toward the clinic.”

About RNAi and sd-rxRNA™

Regarded as a revolutionary discovery in biology, RNAi is a naturally occurring mechanism whereby short, double-stranded RNA molecules interfere with the expression of genes in living cells. This mechanism has the potential to be harnessed to “silence” or specifically block the production of disease-causing proteins before they are made. This technology can potentially be used to treat human diseases by “turning-off” genes that lead to disease in the first place. RXi Pharmaceuticals is using RNAi technology to develop RNA-derived molecules targeting disease-causing genes.

sd-rxRNA™ is a proprietary technology recently developed at RXi which enables the efficient delivery of RNAi compounds without the requirement of an additional delivery vehicle.

About RXi Pharmaceuticals Corporation

RXi Pharmaceuticals is a discovery-stage biopharmaceutical company pursuing the development and commercialization of proprietary therapeutics based on RNA interference (RNAi) for the treatment of human diseases. RXi has a comprehensive therapeutic platform that includes both RNAi compounds and advanced delivery methods. RXi uses its own version of RNAi compounds -- rxRNA™ -- that provide an advanced alternative to conventional small interfering RNAs (siRNAs) and define the next generation of RNAi technology. rxRNA compounds are designed specifically for therapeutic use and contain many of the properties required to progress RNAi based drugs into the clinic. RXi Pharmaceuticals believes it is well positioned to compete successfully in the RNAi-based therapeutics market with its accomplished scientific advisors, including Dr. Craig Mello, recipient of the 2006 Nobel Prize for his co-discovery of RNAi; a management team that is experienced in developing RNAi products; and a strong early intellectual property position in RNAi chemistry and delivery. http://www.rxipharma.com
