Improved Motor Functions In Duchenne Patients

The latest data from REGENXBIO indicate a favorable safety and efficacy profile for RGX-202, a potential gene therapy for Duchenne muscular dystrophy.

Interim results show that pivotal dose participants improved an average of +4.9 points on the North Star Ambulatory Assessment (NSAA) compared to expected disease progression, highlighting the therapy’s potential impact.

NSAA measures functional motor abilities.

In addition, the trial demonstrated cardiac stability among participants, with key measures showing no significant decline over the treatment period.

The company expects to share topline pivotal data in the early second quarter of 2026 and plans to request a pre-BLA meeting with the FDA in mid-2026.

BioMarker Data

Biomarker data continues to support consistent, high expression and transduction of RGX-202 microdystrophin (n=13).

New data from an additional patient, aged 3.6 at dosing, had a microdystrophin expression level of 51.2% at week 12.

In February, the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) to the company’s Biologics License Application (BLA) for RGX-121, for Mucopolysaccharidosis II (MPS II), an ultra-rare neurodegenerative disease also known as Hunter syndrome.
