Methods and compositions for treating and preventing disease associated with αvβ5 integrin
View Patent ↗The present invention provides compositions and methods for treating and preventing disease associated with αvβ5 integrin by blocking binding to αvβ5 integrin. In particular, antibodies specific for αvβ5 integrin are useful for preventing, treating, and reversing sepsis.
1. A method of treating severe sepsis in a human subject in need thereof, the method comprising administering to the human subject a therapeutically effective amount of an antibody specific for αvβ5 integrin, wherein said antibody specifically inhibits ligand binding to αvβ5 integrin and does not significantly bind to at least one of αvβ3, β3, αvβ6, β6, αvβ8 and β8 and wherein the antibody comprises the complementarity determining regions of the ALULA antibody produced by the hybridoma of ATCC Deposit No. PTA-5817.
2. The method of claim 1 , wherein the antibody does not significantly bind to any of αvβ3, β3, αvβ6, β6, αvβ8 or β8.
3. The method of claim 1 , wherein the antibody is a chimeric or a humanized antibody.
4. The method of claim 1 , wherein the ligand is selected from the group consisting of vitronectin, fibronectin, osteopontin, tenascin c, and adenovirus penton base.
5. The method of claim 1 , wherein the antibody is a humanized or chimeric ALULA.
6. The method of claim 1 , wherein the administration is intraperitoneal or intravenous.
7. A method of treating septic shock in a human subject in need thereof, the method comprising administering to the human subject a therapeutically effective amount of an antibody specific for αvβ5 integrin, wherein said antibody specifically inhibits ligand binding to αvβ5 integrin and does not significantly bind to at least one of αvβ3, β3, αvβ6, β6, αvβ8 and β8 and wherein the antibody comprises the complementarity determining regions of the ALULA antibody produced by the hybridoma of ATCC Deposit No. PTA-5817.
8. The method of claim 7 , wherein the antibody does not significantly bind to any of αvβ3, β3, αvβ6, β6, αvβ8 or β8.
9. The method of claim 7 , wherein the antibody is a chimeric or a humanized antibody.
10. The method of claim 7 , wherein the ligand is selected from the group consisting of vitronectin, fibronectin, osteopontin, tenascin c, and adenovirus penton base.
11. The method of claim 7 , wherein the antibody is a humanized or chimeric ALULA.
12. The method of claim 7 , wherein the administration is intraperitoneal or intravenous.
