Antisense composition and method for treating muscle atrophy
First Claim
1. An antisense composition, comprising a substantially uncharged antisense compound(i) composed of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5′
- exocyclic carbon of an adjacent subunit,(ii) capable of uptake by target muscle cells in the subject,(iii) containing between 10-40 nucleotide bases, and(iv) having a base sequence that is complementary to at least 12 contiguous bases in a target region of processed human myostatin transcript identified by SEQ ID NO;
10, where hybridizing of the compound to the target region is effective to block translation of processed human myostatin RNA transcript, andconjugated to the antisense compound, an arginine-rich peptide has the sequence identified by SEQ ID NO;

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.
