  • Publication number: 20070122354
    Abstract: The present invention provides storage stable dry powder compositions of IL-4R. The powder compositions demonstrate superior chemical and physical stability over their solution counterparts, particularly upon storage under varying conditions of temperature and humidity. Moreover, the powders, as prepared, possess good aerosol properties, which are maintained upon storage.

  • Publication number: 20050186143
    Abstract: The present invention provides highly dispersible spray-dried powder compositions, and in particular, inhaleable dry powder compositions for aerosolized delivery to the lungs. The powders of the invention are produced by spray drying a 4 ?-helix bundle protein under conditions which both (i) protect the protein from aggregation and (ii) provide particles suitable for inhalation (i.e., demonstrating superior aerosol performance).

  • Publication number: 20050186146
    Abstract: A powder includes IL-13 antagonist, wherein the powder has a mass median aerodynamic diameter (MMAD) of less than about 10 ?m. A composition includes a spray-dried particle including IL-13 antagonist. A method of administering IL-13 antagonist to the lungs of a subject includes: dispersing a dry powder composition involving IL-13 antagonist to form an aerosol; and delivering the aerosol to the lungs of the subject by inhalation of the aerosol by the subject, thereby ensuring delivery of the IL-13 antagonist to the lungs of the subject. A method of treating an IL-13-related condition includes: pulmonarily administering a therapeutically effective amount of a dry powder including IL-13 antagonist. A method of preparing IL-13 antagonist-containing powder involves: combining IL-13 antagonist, optional excipient, and solvent to form a mixture or solution; and spray drying the mixture or solution to obtain the powder.

  • Publication number: 20050008580
    Abstract: Hemophilia treatment by the inhalation of coagulation factors. Dry powder Factor IX is aerosolized to a mass median aerodynamic diameter of 4 ?m or less, with at least 90% monomer content, at least 80% activity level, and 10% water or less. The aerosol is slowly, and deeply inhaled into the lung, and followed by a maximal exhale.
