ADENO-ASSOCIATED VIRUS FOR THERAPEUTIC DELIVERY TO CENTRAL NERVOUS SYSTEM
A method to prevent, inhibit or treat one or more symptoms associated with disease of the central nervous system by intranasally, intrathecally, intracerebrcvascularly or intravenously administering a rAAV encoding a gene product associated with the disease, e.g., a mammal in which the gene product is absent or present at a reduced level relative to a mammal without the disease, in an amount effective, e.g., to provide for cross-correction.
1 . A composition comprising an amount of a recombinant adeno-associated virus (rAAV) vector comprising an open reading frame encoding iduronate-2-sulfatase, effective to enhance neurocognition in a human having a mucopolysaccharidosis type II (MPSII) disorder relative to a human with MPSII that is not administered the rAAV, wherein the rAAV is AAV9 or AAVrh10.
2 - 8 . (canceled)
9 . The composition of claim 1 wherein the rAAV vector is a rAAV9 vector.
10 . (canceled)
11 . The composition of claim 1 wherein the amount inhibits growth delay, inhibits hepalospenomegaly, inhibits cardiopulmonary disease, or inhibits skeletal dysplasia, or any combination thereof.
12 . The composition of claim 1 wherein the Raav is rAAVrh10.
