Mean muscle content-adjusted dystrophin expression of 9.0% and unadjusted dystrophin of 5.5%, with high consistency across participants, in a prespecified analysis; dystrophin was comprised of two isoforms consistent with Becker muscular dystrophy patients who display milder disease Data demonstrated meaningful improvement in serum biomarkers for muscle health, with localization of WVE-N531 in myogenic stem cells and regeneration of myofibers Skeletal muscle concentrations of ~41,000 ng/g combined with 61-d ...
