Patent application numberDescriptionPublished
20090018097MODIFICATION OF DOUBLE-STRANDED RIBONUCLEIC ACID MOLECULES - A double-stranded RNA (dsRNA) molecule comprising between about 15 base pairs and about 40 base pairs, wherein at least one ribonucleotide of the dsRNA is a 5′-methyl-pyrimidine and/or at least one 2′-O-methyl ribonucleotide, and a method of improving ribonuclease stability, reducing off-target effects of a double stranded siRNA molecule, or of reducing interferon responsiveness of a double stranded siRNA molecule using such dsRNA.01-15-2009
20110123636MICELLIC ASSEMBLIES - Provided herein are micellic assemblies comprising a plurality of copolymers. In certain instances, micellic assemblies provided herein are pH sensitive particles.05-26-2011
20110129921TARGETED POLYMER BIOCONJUGATES - Polymer bioconjugate having a RNAi agent covalently coupled to the alpha or omega end of a pH-dependent membrane-destabilizing polymer.06-02-2011
20110142951MICELLES FOR INTRACELLULAR DELIVERY OF THERAPEUTIC AGENTS - Composition comprising a polymeric micelle and an associated polynucleotide.06-16-2011
20110143434DIBLOCK COPOLYMERS AND POLYNUCLEOTIDE COMPLEXES THEREOF FOR DELIVERY INTO CELLS - Described herein are copolymers, and methods of making and utilizing such copolymers. Such copolymers have at least two blocks: a first block that has at least one unit that is hydrophilic at physiologic pH, and a second block that has hydrophobic groups. This second block further has at least one unit with a group that is anionic at about physiologic pH. The described copolymers are disruptive of a cellular membrane, including an extracellular membrane, an intracellular membrane, a vesicle, an organelle, an endosome, a liposome, or a red blood cell. Preferably, in certain instances, the copolymer disrupts the membrane and enters the intracellular environment. In specific examples, the copolymer is endosomolytic.06-16-2011
20110143435POLYMERIC CARRIER - Provided herein are polymeric carriers suitable for the delivery of polynucleotides (e.g. oligonucleotides) and/or other therapeutic agents into a living cell.06-16-2011
20110281354BISPECIFIC INTRACELLULAR DELIVERY VEHICLES - A composition for delivering an agent to a cell, comprising a bispecific affinity reagent and a pH-responsive, membrane destabilizing polymer. The bispecific affinity reagent may include a first affinity reagent covalently linked to a second affinity reagent, wherein the first affinity reagent binds to a molecule on the surface of a cell, and the second affinity reagent binds to an intracellular target.11-17-2011
20110286957MULTIBLOCK COPOLYMERS - Provided herein are multiblock copolymers, as well as micelles and therapeutic compositions thereof.11-24-2011
