    Abstract: The preparation and use of a transducing polypeptide (TP)- lipid vesicle complex having a small proportion of positively charged (cationic) lipids in the make-up of the lipid vesicle, e.g., liposome, for safe and efficient intracellular delivery of therapeutic agents, such as proteins, DNA, small molecules and/or other drugs, into a cell of a higher organism, in vitro or in vivo is disclosed. The delivery system of the invention results in increased efficacy of intracellular delivery of such agents, bypassing the endocytotic pathway of intracellular delivery while at the same time minimizing the toxicity of the delivery system towards the recipient cells.

    Mixed micelles including amphipathic conjugates ofrna agents, and uses thereof.

    Abstract: Disclosed are improved pharmaceutical formulations for the delivery of RNA interference agents, such as antisense RNA, micro-RNA and siRNA. The formulations employ mixed micelles including amphipathic conjugates of the iRNA agents and amphipathic micelle-forming molecules with extended hydrophilic chains. Also disclosed are methods of using the pharmaceutical formulations to increase delivery of an iRNA agent to an intracellular target, and to decrease extracellular nuclease degradation of an iRNA agent in the formulations.
