  • Publication number: 20210139911
    Abstract: A method and compound for treating skeletal muscle mass deficiency in a human subject are disclosed. The composition is an oligomer of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5? exocyclic carbon of an adjacent subunit, contains between 10-40 nucleotide bases, has a base sequence effective to hybridize to an expression-sensitive region of processed or preprocessed human myostatin RNA transcript, identified, in its processed form, by SEQ ID NO:6, and is capable of uptake by target muscle cells in the subject. In practicing the method, the compound is administered in an amount and at a dosage schedule to produce an overall reduction in the level of serum myostatin measured in the patient, and preferably to bring the myostatin level within the a range determined for normal, healthy individuals.

  • Patent number: 10905782
    Abstract: Compositions and methods for enhancing delivery of molecules, e.g. biological agents, into cells are described. The composition is a conjugate of the biological agent, preferably a nucleic acid analog having a substantially uncharged backbone, covalently linked to a peptide transporter moiety as described. Conjugation of the peptide transporter to a substantially uncharged nucleic acid analog, such as a morpholino oligomer, is also shown to enhance binding of the oligomer to its target sequence and enhance antisense activity.

  • Patent number: 10538769
    Abstract: Compositions and methods for treating hypertension in a subject are provided, including administering an antisense oligomer effective to reduce expression of cytochrome P450 3A5 (CYP3A5) enzyme. The antisense oligomer includes phosphorodiamidate morpholino oligonucleotide (PMO), phosphorothioate 2?-O-methyl oligoribonucleotides (PSO), locked nucleic acid nucleotide, locked nucleic acid analog nucleotide, or another modified oligonucleotide backbone or nuclease-resistant backbone. The antisense oligomer is administered transdermally, subcutaneously, or orally, and optionally with a pharmaceutically acceptable carrier. In one embodiment, the antisense oligomer is an oligomer that is antisense to mRNAs that encode CYP3A5, for instance targeted at the AUG start site of the mRNAs that encode CYP3A5 or at a G4 structure within CYP3A5.

  • Patent number: 10533174
    Abstract: Antisense compositions targeted against an mRNA sequence coding for a selected protein, at a region having its 5? end from 1 to about 25 base pairs downstream of a normal splice acceptor junction in the preprocessed mRNA, are disclosed. The antisense compound is RNase-inactive, and is preferably a phosphorodiamidate-linked morpholino oligonucleotide. Such targeting is effective to inhibit natural mRNA splice processing, produce splice variant mRNAs, and inhibit normal expression of the protein.
