METHOD FOR TREATING OR PREVENTING RADIATION DAMAGE BY IN VIVO GENE THERAPY
The current embodiment provides a method and gene therapy for treating or preventing radiation damage using a vector carrying a gene for extracellular superoxide dismutase (ECSOD). The gene therapy can be used to treat a patient with an effective amount of the therapy to limit damage resulting from exposure to radiation and radiation-like damage.
1 . A method of at least one of treating and preventing radiation damage by:
administering to a patient in need of treatment at least one therapeutically effective amount of a vector carrying an extracellular superoxide dismutase gene to produce and secrete exogenous extracellular superoxide dismutase.
2 . The method of claim 1 , wherein said administering step includes administering in a manner selected from the group consisting of intravenous administration, intra-bone marrow administration, intra-arterial administration, intra-cardiac injection, intracerebral injection, intraspinal injection, intra-peritoneal injection, intra-muscular injection, subcutaneous injection, parenteral administration, intra-rectal administration, intra-tracheal injection, intra-nasal administration, intradermal injection, and combinations thereof.
3 . The method of claim 1 , wherein said administering step includes administering the vector at a location selected from the group consisting of systemically, at the site of injury, at an adjacent site to the site of injury, and at a site remote from the site of injury, wherein the vehicle migrates to the site of injury after administration.
4 . The method of claim 1 , wherein said administering step includes administering to a patient in need of treatment multiple therapeutically effective amounts of the vector.
5 . The method of claim 1 , wherein said administering step includes administering the vector in combination with another therapeutic.
6 . A therapeutic for treating and/or preventing radiation related damage, said therapeutic comprising:
a vector carrying an extracellular superoxide dismutase gene to produce and secrete exogenous extracellular superoxide dismutase.
7 . The therapeutic of claim 6 , wherein said vector is selected from the group consisting of adenovirus vectors, retrovirus vectors, adeno-associated virus vectors, herpes simplex virus vectors, SV 40 vectors, polyoma virus vectors, papilloma virus vectors, picarnovirus vectors, vaccinia virus vectors, a helper-dependent adenovirus, a gutless adenovirus, and a plasmid.
8 . The therapeutic of claim 6 , wherein said extracellular superoxide dismutase gene is a gene selected from the group consisting of human extracellular superoxide dismutase gene and murine extracellular superoxide dismutase gene.
9 . The therapeutic of claim 6 for use in treating radiation damage or radiation-like damage.
10 . The therapeutic of claim 9 , wherein said radiation damage is damage selected from the group consisting of cell injury, tissue damage, organ dysfunction, acute radiation syndrome, radiation-induced lifespan shortening, cataractogenesis, and carcinogenesis.
11 . The therapeutic of claim 6 for use in preventing radiation damage or radiation-like damage.
12 . The therapeutic of claim 11 , wherein said vector is administered prior to exposure to radiation to prevent damage to normal tissue.
13 . The therapeutic of claim 11 , wherein said vector is combined with another unrelated therapy.
14 . A combination therapy for treating or preventing radiation and radiation-like damage, said therapy comprising:
a vector carrying an extracellular superoxide dismutase gene to produce and secrete exogenous extracellular superoxide dismutase; and
an unrelated therapeutic.
15 . The therapy of claim 14 , wherein said vector is selected from the group consisting of adenovirus vectors, retrovirus vectors, adeno-associated virus vectors, herpes simplex virus vectors, SV 40 vectors, polyoma virus vectors, papilloma virus vectors, picarnovirus vectors, vaccinia virus vectors, a helper-dependent adenovirus, a gutless adenovirus, and plasmid.
16 . The therapy of claim 14 , wherein said extracellular superoxide dismutase gene is a gene selected from the group consisting of human extracellular superoxide dismutase gene and murine extracellular superoxide dismutase gene.
17 . The therapy of claim 14 , wherein said unrelated therapeutic is selected from the group consisting of a radiotherapeutic and chemotherapeutic.
