  • Publication number: 20080081366
    Abstract: A lyophilized polynucleotide composition contains at least one polynucleotide and at least one cryoprotectant, wherein the ratio of the polynucleotide to cryoprotectant is from about 0.001 to about 1.0 part by weight polynucleotide per 1.0 part by weight of the cryoprotectant. This composition also contains from about 0.5 weight percent to about (6) weight percent water, based on the total weight of the final lyophilized polynucleotide composition. The polynucleotide composition of this invention is characterized by enhanced stability, in that it retains at least 90% supercoil over a time period of at least (10) days at a temperature of about 37° C. The lyophilized polynucleotide composition also has improved solubility. An improved process for lyophilization of polynucleotides employs a specific primary drying cycle, that results in the above-described stable, lyophilized polynucleotide composition.

  • Patent number: 6482804
    Abstract: A soluble ionic complex is formed by an aqueous mixture of a benzylammonium group-containing surfactant and a polynucleic acid sequence. When the mixture forms a vesicular complex, the sequence is packaged therein. This composition is useful in pharmaceutical compositions and in methods of delivering the polynucleic acid sequence (which preferably encodes a protein or peptide) to a cell for expression. Such methods are useful in therapy, as vaccines and as gene therapy agents.

  • Patent number: 6410511
    Abstract: The present invention is concerned with a pharmaceutical formulation in a container, for example, a vial, prefilled cartridge, prefilled syringe or disposable pen, comprising approximately 0.01 to about 0.5% (w/v) amylin agonist, preferably pramlintide, in an aqueous system along with approximately 0.02 to about 0.5% (w/v) of an acetate, phosphate, citrate, or glutamate buffer to a pH of the final composition of approximately 3.0 to about 6.0 as well as approximately 1.0 to 10% (w/v) of a carbohydrate or polyhydric alcohol tonicifier; and, optionally, approximately 0.005 to 1.0% (w/v) of a preservative selected from the group consisting of m-cresol, benzyl alcohol, parabens and phenol. These formulations maintain stability upon storage under refrigerated or room temperature conditions. Such formulations can be further combined with insulin in the same syringe for administration to a patient.

  • Patent number: 5451409
    Abstract: The present invention is directed to a novel sustained release matrix and oral dosage form comprising a homogeneous matrix formed from a wet granulation containing an effective amount of a medicament and a polymer blend of hydroxypropyl cellulose and hydroxyethyl cellulose. The present invention also discloses a novel process for making a sustained release oral dosage form comprising wet granulating a medicament with a polymer blend of hydroxypropyl cellulose and hydroxyethyl cellulose to form a homogeneous matrix, wherein the polymer blend is provided in an amount effective to control the release of said medicament, then forming the homogenous matrix into a solid oral dosage form.
