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
