About PBGENE-DMD

PBGENE-DMD, a novel first-in-class gene editing therapy, utilizes a gene excision approach that is clearly differentiated from existing microdystrophin and exon skipping treatments. PBGENE-DMD is designed to potentially provide durable functional muscle improvement for DMD patients with mutations between exons 45 and 55, which impact up to 60% of boys with DMD. A single AAV encodes two ARCUS proteins designed to permanently edit a patient’s DNA within the dystrophin gene, resulting in a naturally-expressed, near full-length, functional dystrophin protein. Supported by robust preclinical evidence, PBGENE-DMD is designed to drive functional improvement in skeletal and cardiac muscle over time with the ability to target and edit muscle satellite cells.

In preclinical studies, PBGENE-DMD demonstrated the ability to target key muscle types involved in the progression of DMD and produced significant, durable functional improvements in a humanized DMD mouse model. PBGENE-DMD restored production of a near full-length functional dystrophin protein across multiple muscles, including cardiac tissue and various key skeletal muscle groups. In addition, PBGENE-DMD edited satellite muscle stem cells, believed to be critical for long-term durability and sustained functional improvement.

PBGENE-DMD has received Investigational New Drug clearance from the U.S. Food and Drug Administration (FDA) enabling initiation of clinical trial site activation. PBGENE-DMD was previously granted FDA Rare Pediatric Disease (RPD) and Orphan Drug (ODD) designation for the treatment of DMD.
