Overview

RC-1001 is a peptide-conjugated phosphorodiamidate morpholino oligomer (PPMO) developed by Sarepta Therapeutics as a preclinical research tool and mouse surrogate for Duchenne muscular dystrophy (DMD) therapy. It comprises a morpholino antisense oligonucleotide (PMO) covalently linked to a cell-penetrating peptide (CPP) to enhance cellular uptake and nuclear delivery. RC-1001 specifically targets exon 23 of the murine dystrophin gene in mdx mice, inducing exon skipping to restore the mRNA reading frame and promote the expression of a functional, truncated dystrophin protein. It has been extensively used in pharmacokinetic and pharmacodynamic (PK/PD) modeling to characterize the relationship between plasma/tissue exposure and biological response, supporting the translation of PPMO technology into clinical candidates such as vesirplirsen (SRP-5051).
