  • Compositions and methods for nucleic acid delivery to the lung
    Patent number: 5994314
    Abstract: A dry powder composition comprises insoluble nucleic acid constructs dispersed within with a hydrophilic excipient material, where the powder particles have an average size in the range from 0.5 .mu.m to 50 .mu.m. Nucleic acid constructs may comprise bare nucleic acid molecules, viral vectors, or vesicle structures. The hydrophilic excipient material will be selected to stabilize the nucleic acid molecules in the constructs, enhance dispersion of the nucleic acid in dry powder aerosols, and enhance wetting of the nucleic acid constructs as they are delivered to moist target locations within the body.
    Type: Grant
    Filed: April 14, 1995
    Date of Patent: November 30, 1999

  • Method and apparatus for pulmonary administration of dry powder .alpha.1-antitrypsin
    Patent number: 5993783
    Abstract: Dry powders of .alpha.1-antitrypsin are administered pulmonarily to patients to treat, for example, certain types of emphysema. The dry powder compositions may comprise aggregates of fine particles, which aggregates are friable and break-up upon dispersion in a flowing gas stream. Typically, the dispersed powders are captured in a chamber and subsequently inhaled by a patient for pulmonary treatment of emphysema and other conditions.
    Type: Grant
    Filed: July 13, 1998
    Date of Patent: November 30, 1999
    Assignee: Inhale Therapeutic Systems
    Inventors: Mohammed Eljamal, John S. Patton
  • Method and apparatus for pulmonary administration of dry powder alpha 1-antitrypsin
    Patent number: 5780014
    Abstract: Methods are provided for administering .alpha.1-antitrypsin dry powder pulmonarily to a patient. In these methods, .alpha.1-antitrypsin is provided in a dry powder form which is aerosolized and administered to the patient. Apparatus are also provided for carrying out these methods. These methods and apparatus are may generally be used in the treatment of patients suffering from .alpha.1-antitrypsin deficiency and the functional derangements of emphysema.
