Summary for Patent: 7,034,007

Title:	Low adenosine anti-sense oligonucleotide, compositions, kit & method for treatment of airway disorders associated with bronchoconstriction, lung inflammation, allergy(ies) & surfactant depletion
Abstract:	An in vivo method of selectively delivering a nucleic acid to a target gene or mRNA, comprises the topical administration, e.g. to the respiratory system, of a subject of a therapeutic amount of an oligonucleotide (oligo) that is anti-sense to a mRNA complementary to the gene in an amount effective to reach the target polynucleotide and reducing or inhibiting expression. The composition and formulations are used for prophylactic, preventive and therapeutic treatment of ailments associated with impaired respiration, lung allergy(ies) and/or inflammation and depletion lung surfactant or surfactant hypoproduction, such as pulmonary vasoconstriction, inflammation, allergies, allergic rhinitis, asthma, impeded respiration, lung pain, cystic fibrosis, bronchoconstriction. The treatment of this invention may be administered directly into the respiratory system of a subject so that the agent has direct access to the lungs, in an amount effective to reduce or inhibit the symptoms of the ailment.

Application Number:	09/543,679
Patent Claims:	1. An in vivo method of delivering a pharmaceutical composition to a subject comprising administering to the airways of said subject a pharmaceutical composition comprising a respirable or inhalable pharmaceutical composition having a particle size of 0.5 .mu.m to 10 .mu.m in size, comprising at least one antisense oligonucleotide effective to alleviate hyper-responsiveness to adenosine or increased levels of adenosine, wherein the antisense oligonucleotide is 7 to 60 nucleotides long and contains up to and including about 15% adenosine or less adenosine, pharmaceutically or veterinarily acceptable salts of the oligonucleotide, mixtures of the oligonucleotide or their salts. 2. The method of claim 1, wherein the antisense oligonucleotide comprises 10% or less adenosine. 3. The method of claim 1, wherein the antisense oligonucleotide comprises 5% or less adenosine. 4. The method of claim 3, wherein the antisense oligonucleotide comprises 5% or less adenosine. 5. The method of claim 4, wherein the antisense oligonucleotide is adenosine-free. 6. The method of claim 1, wherein the antisense oligonucleotide is 10 to 36 nucleotides long. 7. The method of claim 6, wherein the antisense oligonucleotide is 12 or 21 nucleotides long. 8. The method of claim 1, wherein the pharmaceutical composition is administered by inhalation directly to the lung of the subject. 9. The method of claim 1, wherein the pharmaceutical composition further comprises a surfactant. 10. The method of claim 1, wherein the antisense oligonucleotide is administered in an amount of about 0.01 to about 150 mg/kg body weight. 11. The method of claim 1, wherein the antisense oligonucleotide is antisense to the initiation codon, the coding region or the 5' or 3' intron-exon junctions of a gene encoding bradykinin B2 receptor. 12. The method of claim 1, wherein the antisense oligonucleotide comprises at least one mononucleotide is linked or modified by one or more of phosphorothioate, phosphorodithioate, methylphosphonate, phosphoramidate, bomraophosphate, 3'-thioformacetal, triformacetal, carbamate, phosphotriester, formacetal, 2'-O-methyl, thioformacetal, 5'-thioether, carbonate, 5'-N-carbamate, sulfate sulfonate, sulfamate, sulfonamide, sulfone, sulfite, sulfoxide, sulfide, hydroxylamine, methylene (methylimino), methyleneoxy (methylimino), methoxyethyl, C.sub.5-substituted nucleotide and methyloxyethyl.
