Abstract

The present invention relates to ocular administration of sd-rxRNA and rxRNAori molecules.

Claims

1. A method for delivering a nucleic acid to an eye of a subject in need thereof, comprising

administering to the eye of the subject an sd-rxRNA®

, in an effective amount to promote RNA interference by the sd-rxRNA®

in the eye,

wherein the sd-rxRNA®

comprises a guide strand and a passenger strand, wherein the sd-rxRNA®

includes a double stranded region and a single stranded region, wherein the double stranded region is from 8-15 nucleotides long, wherein the single stranded region is at the 3′

end of the guide strand and is 4-12 nucleotides long, wherein the single stranded region contains 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 phosphorothioate modifications, wherein at least 40% of the nucleotides of the isolated double stranded nucleic acid molecule are modified,

wherein the sd-rxRNA®

is directed against a gene encoding VEGF or CTGF, and

wherein the sd-rxRNA®

comprises at least 12 contiguous nucleotides of a sequence selected from the sequences within Tables 5, 8 or 10.

2. The method of claim 1, wherein the administration of the sd-rxRNA®

is intravitreal.
