TS-000513 — Dystrophinopathies are a group of disorders caused by mutations in the DMD gene which codes for dystrophin, the vital, muscle-specific structural protein. Currently, there is no cure for muscular dystrophy, and patients only rely on palliative care options. Our gene therapy researchers at Nationwide Children’s Hospital have developed an AAV-mediated gene editing method for correcting deleterious DMD mutations in affected patients. This therapy uses a homology-independent targeted integration (HITI) to replace any missing or aberrant exons in affected patients; therefore, correcting the underlying cause of DMD. This therapy will be developed to stop the progression of muscle wasting and fibrosis in individuals with DMD mutations that result in muscular dystrophy via permanent correct of the underlying cause within muscle tissue by replacing missing or aberrant exons using HITI. Advantages By developing AAV-Mediated HITI gene editing for correction of diverse DMD mutations in patients with muscular dystrophy, we can potentially cure BMD and DMD patients. These patients currently have no palliative care options. Our compositions of matter for this approach (i.e. genomic target region, guide-RNA sequences, donor DNA sequences) are new.
