Research summary
The Pharma Partner (PP) is developing a gene therapy treatment, called delandistrogene moxeparvovec which is based on recombinant adeno-associated viral vector (AAVrh74). Delandistrogene moxeparvovec is a gene therapy designed to treat patients with Duchenne Muscular Dystrophy. DMD is a rare neuromuscular disorder that occurs due to mutations in the Dystrophin gene which prohibit proper production of the dystrophin protein. This protein is required to stabilize muscle fibers and it’s absence results in progressive loss of motility and, in most cases, death in the late teens/early 20’s due to cardiac arrest. Elevated neutralizing antibody levels against recombinant AAVrh74 vector are an exclusion criterion for enrollment in the clinical trial subsequent treatment with delandistrogene moxeparvovec. Therefore, following the collaboration with PP, RD006698 study will support patient screening for the ENVOL Phase II clinical study (BN43881) by investigating the delandistrogene moxeparvovec treatment using Elecsys® Anti-AAVrh74 assay. All clinical samples will be collected under the ENVOL clinical protocol and measured prospectively with the Elecsys® Anti-AAVrh74 assay under RD006698 clinical performance evaluation study protocol.
