About RXi Pharmaceuticals Corporation RXi Pharmaceuticals Corporation (OTC: RXII) is a biotechnology company focused on discovering, developing and commercializing innovative therapies based on its proprietary, self-delivering RNAi platform. Therapeutics that use RNA interference, or “RNAi,” have great promise because of their ability to down-regulate the expression of a specific gene that may be over-expressed in a disease condition. Building on the pioneering work of scientific founder and Nobel Laureate Dr. Craig Mello, a member of the RXi Scientific Advisory Board, RXi’s first RNAi product candidate, RXI-109, which targets CTGF, entered into human clinical development in June 2012.
