Modulation of immunostimulatory properties of oligonucleotide-based compounds by optimal presentation of 5′ ends
View Patent ↗The invention relates to the therapeutic use of oligonucleotides as immunostimulatory agents in immunotherapy applications. More particularly, the invention provides immunomers for use in methods for generating an immune response or for treating a patient in need of immunostimulation. The immunomers of the invention comprise at least two oligonucleotides linked at their 3′ ends, internucleoside linkages or functionalized nucleobase or sugar to a non-nucleotidic linker, at least one of the oligonucleotides being an immunostimulatory oligonucleotide and having an accessible 5′ end.
1. A method for therapeutically treating a vertebrate having cancer, an autoimmune disorder, airway inflammation, inflammatory disorders, skin disorders, allergy, asthma or a disease caused by a pathogen, such method comprising administering to the vertebrate an immunostimulatory oligonucleotide having the structure
2. The method according to claim 1 , wherein the route of administration is selected from parenteral, oral, sublingual, transdermal, topical, intranasal, aerosol, intraocular, intratracheal, intrarectal, vaginal, gene gun, dermal patch, eye drop and mouthwash.
3. A pharmaceutical composition comprising an immunostimulatory oligonucleotide having the structure
and a physiologically acceptable carrier.
4. The pharmaceutical composition according to claim 3 , further comprising an antibody, antisense oligonucleotide, protein, antigen, allergen, chemotherapeutic agent or adjuvant.
5. The method according to claim 1 , further comprising administering an antibody, antisense oligonucleotide, protein, antigen, allergen, chemotherapeutic agent or adjuvant.
6. A method for generating an immune response in a vertebrate, the method comprising administering to the vertebrate an immunostimulatory oligonucleotide having the structure
7. The method according to claim 6 , wherein the route of administration is selected from parenteral, oral, sublingual, transdermal, topical, intranasal, aerosol, intraocular, intratracheal, intrarectal, vaginal, gene gun, dermal patch, eye drop and mouthwash.
8. The method according to claim 6 , further comprising administering an antibody, antisense oligonucleotide, protein, antigen, allergen, chemotherapeutic agent or adjuvant.
