  • Publication number: 20030092666
    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 &mgr;m to 50 &mgr;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.

  • Publication number: 20030072718
    Abstract: According to the present invention, methods and compositions are provided for spray-dried, interferon-based dry powder compositions, particularly interferon-beta. The compositions are useful for treating conditions in humans that are responsive to treatment with interferons. In particular, the methods of the present invention rely on spray drying to produce stable, high-potency dry powder formulations of interferons, including but not limited to IFN-beta. Surprisingly, it has been found that IFN can be prepared in high potency, dry powder formulations by spray drying. Such dry powder formulations find particular utility in the pulmonary delivery of IFN.

  • Publication number: 20030044460
    Abstract: The present invention provides exemplary systems and methods for producing dry powder formulations. In one embodiment, a system (10) includes at least one conditioning zone (12) having an inlet (20) to introduce an atomized formulation (18) into the conditioning zone. A controller (14, 16) controls temperature and relative humidity of the airflow into the conditioning zone to allow amorphous-to-crystalline transformation of the atomized formulation. In another embodiment, the formulation is suspended in the conditioning zone for a residence time of sufficient duration to allow surface orientation of surface active components. A dryer (24) is coupled to the conditioning zone to dry the atomized formulation, and a collector (28) collects the formulation in powder form.
