Stable pharmaceutical compositions comprising recombinant adeno-associated
virus (AAV) virions are described. The compositions provide protection
against loss of recombinant AAV vector genomes and transduceability under
conditions such as exposure to cycles of freezing and thawing and storage
in glass or polypropylene vials. The compositions comprise recombinant
AAV virions in combination with one or more dihydric or polyhydric
alcohols, and, optionally, a detergent, such as a sorbitan ester. Also
described are methods of using the compositions.
