Anti-virus therapy for respiratory diseases
View Patent ↗The present invention provides the use of IFN-β, an agent that increases the expression of IFN-β, or a polynucleotide which is capable of expressing IFN-β or said agent for the manufacture of a medicament for the treatment of rhinovirus-induced exacerbation of a respiratory disease selected from asthma and chronic obstructive pulmonary disease, wherein said treatment is by airway delivery of said medicament, e.g. by use of an aerosol nebuliser. Also provided is IFN-λ for the same purpose.
1. A method of treating in an individual a rhinovirus-induced exacerbation of a respiratory disease selected from asthma and COPD, comprising administering interferon-β (IFN-β) to the lower respiratory tract, wherein the administration results in suppression of rhinovirus replication in the individual.
2. A method according to claim 1 , wherein said respiratory disease is asthma.
3. A method according to claim 2 wherein said IFN-β is administered simultaneously, separately or sequentially with an inhaled corticosteroid.
4. The method according to claim 1 , wherein the IFN-β comprises the sequence of:
(a) human IFNβ-1a (SEQ ID NO: 2); or
(b) human IFNβ-1b (SEQ ID NO: 4).
5. A method according to claim 1 , wherein the IFN-β is administered to lung airways by means of an aerosol nebuliser.
