20100255100 | STABILIZED PROTEIN CRYSTALS, FORMULATIONS COMPRISING THEM AND METHODS OF MAKING THEM - This invention relates to methods for the stabilization, storage and delivery of biologically active macromolecules, such as proteins, peptides and nucleic acids. In particular, this invention relates to protein or nucleic acid crystals, formulations and compositions comprising them. Methods are provided for the crystallization of proteins and nucleic acids and for the preparation of stabilized protein or nucleic acid crystals for use in dry or slurry formulations. The present invention is further directed to encapsulating proteins, glycoproteins, enzymes, antibodies, hormones and peptide crystals or crystal formulations into compositions for biological delivery to humans and animals. According to this invention, protein crystals or crystal formulations are encapsulated within a matrix comprising a polymeric carrier to form a composition. The formulations and compositions enhance preservation of the native biologically active tertiary structure of the proteins and create a reservoir which can slowly release active protein where and when it is needed. Methods are provided preparing stabilized formulations using pharmaceutical ingredients or excipients and optionally encapsulating them in a polymeric carrier to produce compositions and using such protein crystal formulations and compositions for biomedical applications, including delivery of therapeutic proteins and vaccines. Additional uses for-the protein crystal formulations and compositions of this invention involve protein delivery in human food, agricultural feeds, veterinary compositions, diagnostics, cosmetics and personal care compositions. | 10-07-2010 |
20090093617 | Crystals of whole antibodies and fragments thereof and methods for making and using them - This invention relates to crystals of whole antibodies and fragments thereof, and formulations and compositions comprising such crystals. More particularly, methods are provided for the crystallization of high concentrations of whole antibodies, and fragments thereof, in large batches, and for the preparation of stabilized whole antibody crystals for use alone, or in dry or slurry formulations or compositions. This invention also relates to methods for stabilization, storage and delivery of biologically active whole antibody crystals. The present invention further relates to methods using whole antibody crystals, antibody fragment crystals, or compositions or formulations comprising such crystals for biomedical applications, including biological delivery to humans and animals. More particularly, whole antibody crystals or antibody fragment crystals, or crystal compositions or formulations thereof, are used as a carrier-free delivery system which can slowly release active whole antibodies or fragments thereof, to a subject, where and when they are needed. | 04-09-2009 |
20090081184 | NON-PANCREATIC PROTEASES FOR CONTROLLING PLASMA CHOLECYSTOKININ (CCK) CONCENTRATION AND FOR TREATING PAIN - This invention relates to methods for maintaining the basal level or reducing the level of cholecystokinin (CCK) in blood plasma of a mammal. Additionally, the invention provides methods for treating pain in a mammal and more particularly, methods for treating abdominal pain in a mammal. The methods include administering to the mammal a non-pancreatic protease or a composition comprising a non-pancreatic protease. The methods of this invention are particularly useful for treating abdominal pain in a mammal suffering from acute or chronic pancreatitis and related conditions. | 03-26-2009 |
20090023629 | COMPOSITIONS COMPRISING POLYCATION-COMPLEXED PROTEIN CRYSTALS AND METHODS OF TREATMENT USING THEM - The present invention relates to compositions comprising polycation-complexed protein crystals and hyaluronic acid. Advantageously, the compositions of this invention are stable, long-acting and avoid local reactions at the injection site. Compositions according to this invention include sustained-release human growth hormone compositions. Such compositions are useful for treating a subject having a disorder associated with human growth hormone deficiency or that is ameliorated by human growth hormone therapy. | 01-22-2009 |
