  • Patent number: 8590530
    Abstract: A nasal delivery device for and method of delivering substance to a nasal cavity of a subject, the delivery device comprising: a container-receiving unit comprising a container chamber for receiving a substance-containing container which contains substance to be delivered to the nasal cavity of the subject, the container chamber including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the container chamber; a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the container chamber and through which the subject in use exhales, such as to entrain substance from the container and deliver the same through the nosepiece; and moisture-mitigation means for mitigating an effect of moisture in an exhaled breath on the entrainment of substance from the container.

  • Publication number: 20110206709
    Abstract: A first or second polypeptide for use in a method of treating or preventing a disorder by tolerisation, wherein said method comprises administration of the first and second polypeptide; and wherein both first and second polypeptides: i) are of 7 to 30 amino acids in length; ii) comprise at least one MHC Class Il-binding T cell epitope; and iii) are a fragment of a protein allergen or a homologous variant of said fragment; wherein said first polypeptide induces the release of an amount of IL-10 that is greater than the amount of IL-10 released in response to the whole protein allergen from which the first polypeptide derives; wherein said disorder is characterised by an inappropriate immune response to the protein allergen from which the second polypeptide derives.

  • Publication number: 20110114087
    Abstract: A delivery device for and method of providing for delivery of substance to the central nervous system (CNS) of a subject, the delivery device comprising: a nosepiece unit (17) for insertion into a nasal airway (1) of a subject and comprising an outlet unit (21) which includes a nozzle (25) for delivering substance into the nasal airway of the subject; and a substance supply unit which is operable to deliver a dose of substance to the nozzle: wherein the delivery device is configured such that at least 30% of the dose as initially deposited in the nasal airway is deposited in an upper posterior region of the nasal airway, thereby providing a CNS concentration of the substance, and hence CNS effect, which is significantly greater than that which would be predicted from a counterpart blood plasma concentration of the substance.
