Splice switch oligomers for TNF superfamily receptors and their use in treatment of disease
First Claim
1. A method of treating an inflammatory disease or condition which comprises administering one or more splice switching oligomers (SSOs) to a subject for a time and in an amount to reduce the activity of a ligand for a receptor of the tumor necrosis factor receptor (TNFR) superfamily, wherein said one or more SSOs are capable of altering the splicing of a pre-mRNA encoding said receptor to increase production of a stable, secreted, ligand-binding form of said receptor.

Abstract
Methods and compositions are disclosed for controlling expression of TNF receptors (TNFR1 and TNFR2) and of other receptors in the TNFR superfamily using compounds that modulate splicing of pre-mRNA encoding these receptors. More specifically these compounds cause the removal of the transmembrane domains of these receptors and produce soluble forms of the receptor which act as an antagonist to reduce TNF-α activity or activity of the relevant ligand. Reducing TNF-α activity provides a method of treating or ameliorating inflammatory diseases or conditions associated with TNF-α activity. Similarly, diseases associated with other ligands can be treated in like manner. In particular, the compounds of the invention are splice-splice switching oligomers (SSOs) which are small molecules that are stable in vivo, hybridize to the RNA in a sequence specific manner and, in conjunction with their target, are not degraded by RNAse H.
