Evaluating AAV8 Antibodies in Boys with Duchenne Muscular Dystrophy

Anti-AAV8 Antibody Assessment Study of Males With Duchenne Muscular Dystrophy Aged 0 to <25 Years

Observational REGENXBIO Inc. · NCT05683379

This study is testing how common certain antibodies are in boys with Duchenne muscular dystrophy to help find out who might be able to join future gene therapy trials.

What this trial studies

This observational study aims to assess the prevalence of anti-adeno-associated serotype 8 (AAV8) antibodies in boys diagnosed with Duchenne muscular dystrophy (DMD). Participants will undergo a phone or video interview for consent and medical history, followed by a home health visit to collect blood samples for antibody testing. The results may help identify potential candidates for future gene therapy clinical trials targeting DMD.

Who should consider this trial

Good fit: Ideal candidates are males aged 0 to under 12 years with a confirmed diagnosis of Duchenne muscular dystrophy.

Not a fit: Patients who have previously participated in a gene therapy trial or received a gene therapy drug may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the identification of suitable candidates for innovative gene therapies in DMD.

How similar studies have performed: While this study focuses on antibody prevalence, similar approaches in gene therapy trials have shown promise in identifying suitable candidates.
