Wave Life Sciences Announces Positive Interim Data from FORWARD-53 Clinical Trial Evaluating WVE-N531 in Boys with Duchenne Muscular Dystrophy Amenable to Exon 53 Skipping

September 24, 2024 7:30 AM EDT

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-day tissue half-life support monthly dosing going forward; preclinical data suggest participants may have even higher concentrations in heart and diaphragm

WVE-N531 was safe and well... More
