  • Publication number: 20210369256
    Abstract: A method for collecting a cell sample, including eosinophil white blood cells in a patient is provided. The method includes advancing to a location in an esophagus associated with eosinophilic esophagitis (EoE), a device provided with a collection portion having a first axial end portion and an inflatable second axial end portion. Thereafter, axially moving the second axial end portion, relative to the first axial end portion, from a collapsed position within the first axial end portion into an expanded position out from the first axial end portion. Once the second axial end portion is in the expanded position, allowing it to engage the location associated with EoE to collect a sample of cells.

  • Publication number: 20200297822
    Abstract: The present invention provides a method of reducing the quantity of mucus in the respiratory tract of a subject with elevated levels of mucus in said respiratory tract. The method includes administering to the subject a compound or composition containing a therapeutically effective amount of a fusion protein comprising a sialidase or an active portion thereof and an anchoring domain. The therapeutically effective amount comprises an amount of the fusion protein that results in a reduction of the quantity of mucus in the respiratory tract after administration of the compound or composition when compared to the quantity of mucus present prior to administration of the compound or composition.

  • Publication number: 20090214643
    Abstract: Methods for administering beta-adrenergic inverse agonists with improved pharmacokinetic profiles for the treatment of pulmonary airway diseases are disclosed. The beta adrenergic inverse agonists are formulated in a controlled-release formulation comprising: (1) a beta-adrenergic inverse agonist in a therapeutically effective quantity; and (2) at least one agent that controls release of the beta-adrenergic inverse agonist resulting in a pharmacokinetic profile that minimizes acute detrimental reduction in airway function with the first dose and with each successive dose. This pharmacokinetic profile typically results in slow release of the drug into the bloodstream resulting in a large average Tmax>4 hours. The controlled-release formulation may consist of multilayered matrix or erosional tablets, gastric-retention tablets, osmotic pump oral formulations, multiparticulate capsules or tablets or dermal patch.
