Patent number: 12359197Abstract: The present invention includes compositions and methods for the treatment of a medical condition or disease utilizing editing oligonucleotides. The editing oligonucleotides contain an oligonucleotide strand of about 10 to about 50 nucleotides on each side of the editing moiety which may contain a sugar or linker that positions the active editing moiety in the proper location for hybridization to the target nucleic acid. The editing oligonucleotides may also contain at least one nucleotide sequence change from the targeted sequence in the genome. The method includes modifying a genomic sequence within a cell utilizing an editing oligonucleotide without additional proteins or nucleic acids to assist in the editing process. The editing oligonucleotide may comprise backbone modifications that increase the nuclease stability of the oligonucleotide as compared to unmodified oligonucleotides or oligonucleotides having three phosphorothioates on each terminus.Type: GrantFiled: December 11, 2015Date of Patent: July 15, 2025Assignee: Etagen Pharma, Inc.Inventors: Tod M. Woolf, Alexandre V. Lebedev, Richard I. Hogrefe
