Patent number: 6753006Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of a pharmaceutically active agent, wherein the agent is associated with a polymeric biocompatible material.Type: GrantFiled: July 31, 2000Date of Patent: June 22, 2004Assignee: American BioScience, Inc.Inventors: Neil P.

Patent number: 6749868Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful election of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered.Type: GrantFiled: May 21, 1999Date of Patent: June 15, 2004Assignee: American BioScience, Inc.Inventors: Neil P. Desai, Chunlin Tao, Andrew Yang, Leslie Louie, Zhiwen Yao, Patrick Soon-Shiong, Shlomo Magdassi

Patent number: 6565842Abstract: In accordance with the present invention, there are provided rapidly crosslinkable polypeptides which are obtained upon introduction of unsaturated group(s) into the polypeptide via linkage to amino acid residues on the polypeptide directly through one of three types of linkages, namely, an amide linkage, an ester linkage, or a thioester linkage. Each of these linkages are obtainable in a single step by use of a single derivatizing agent, acrylic anhydride. Also provided are methods for preparing such modified polypeptides and various uses therefor. It has unexpectedly been found that proteins with the above-described chemical modifications have the ability to rapidly crosslink to themselves under suitable conditions. This crosslinking occurs in the absence of any external crosslinking agents (indeed, in the absence of any extraneous agents), resulting in the formation of a solid gel material. Solid crosslinked gels are formed in seconds, starting from a freely flowing solution of polypeptide.Type: GrantFiled: June 7, 1995Date of Patent: May 20, 2003Assignee: American Bioscience, Inc.Inventors: Soebianto A.

Patent number: 6528067Abstract: In accordance with the present invention, there are provided stabilized total nutrient admixture (TNA) compositions which are useful for the in vivo parenteral delivery of pharmacologically acceptable lipids or fats, as well as methods for the preparation thereof. In particular, the pharmacologically acceptable lipid or fat is contained within a protein walled shell. In a particular embodiment of the invention, a TNA composition using human serum albumin (HSA) as a stabilizer has been prepared as a convenient three-in-one formulation (i.e., containing a fat emulsion, dextrose, and amino acids plus electrolytes). This “three-in-one” formulation can be prepared in liquid form or in dry form (comprising submicron-sized nanoparticles). The dried material is stable, even under long term storage, and is easily reconstituted immediately before use by simply adding sterile water (with or without vitamin supplementation) This serves to rehydrate the powder into a TNA suitable for injection.Type: GrantFiled: December 7, 1999Date of Patent: March 4, 2003Assignee: American Bioscience, Inc.Inventors: Shlomo Magdassi, Andrew Yang, Chunlin Tao, Neil P.
