Title:	Non-ionic, low osmolar contrast agents for delivery of antisense oligonucleotides and treatment of disease
Abstract:	Disclosed are compositions comprising an antisense oligonucleotide and a non-ionic, low-osmolar contrast agent. Also disclosed are methods of delivering an antisense oligonucleotide to a target sire comprising incorporating the antisense oligonucleotide into a composition comprising a non-ionic, low-osmolar contrast agent. Also disclosed are methods of treating a neurodegenerative disease comprising administering one or more of the compositions disclosed herein.

Application Number:	14/363,670
Patent Claims:	1. A composition comprising an antisense oligonucleotide complexed to a non-ionic, low-osmolar contrast agent. 2. The composition of claim 1, wherein the low-osmolar contrast agent is iobitridol, iohexol, iomeprol, iopamidol, iopentol, iopromide, ioversol or ioxilan. 3. The composition of claim 2, wherein the non-ionic, low-osmolar contrast agent is iohexol. 4. The composition of claim 1, wherein the antisense oligonucleotide is a morpholino, siRNA, or shRNA. 5. The composition of claim 4, wherein the antisense oligonucleotide disrupts translation, binds to a target nucleotide, induces exon skipping, blocks an intron splice silencer, blocks an exon splice enhancer, binds to a repeat nucleotide sequence, or blocks binding to a sequence in toxic RNA. 6. The composition of claim 1, wherein the antisense oligonucleotide is a morpholino that binds to a survival motor neuron (SMN) gene, a mutated SOD1 gene, C9orf72 repeats, alpha-synuclein, dystrophia myotonic protein kinase gene (DMPK) repeats, Zinc Finger Protein 9 (ZNF9) repeats, a negative regulatory element in intro 6 or intron 7 of SMN2. 7. The composition of claim 1, wherein the morpholino comprises the sequence set forth in SEQ ID NO: 5, SEQ ID NO: 6, or SEQ ID NO: 7. 8. A method of delivering an antisense oligonucleotide to a tissue, organ, or system in a subject comprising administering to the subject the composition of claim 1. 9. A method of treating a neurological disease in a patient in need thereof comprising administering to the patient the composition of claim 1. 10. The method of claim 9, wherein the neurological disease is selected from the group consisting of Alzheimer's disease, Spinal muscular atrophy (SMA), Myotonic dystrophy, Huntington's disease, Parkinson's disease, Spinocerebellar degeneration, Spinocerebellar ataxia, Friedreich's ataxia, Ataxia telangiectasia, amyotrophic lateral sclerosis, Charcot-Marie-Tooth disease, Vasomotor ataxia, Vestibulocerebellar, Ataxiadynamia, Ataxiophemia, Amyotrophic lateral sclerosis, and Olivopontocerebellar atrophy.
