TS-000639 — Infectious recombinant Adeno-associated virus (rAAV) are exclusively used as gene transfer vehicles for an ever-widening array of human applications such as for use as vaccines and gene therapy vectors. A requirement for the clinical use of rAAV for DNA delivery is a highly efficient, reproducible and commercially scalable production. The most common methods of scalable rAAV production use HeLa cells. HeLa cells are derived from malignant cervical tumor and therefore, raises potential safety concerns. Gene therapy experts at Nationwide Children’s Hospital have developed new methods and materials achieving higher titers of rAAV in mammalian cells other than transformed cancer cells. This invention achieves scalable production of rAAV using clinically safe Vero cells derived from African green monkey kidney cells combined with the simian adenovirus 13 helper virus.

TS-000438 — Gene therapy experts at Nationwide Children’s have developed an AAV-mediated CRISPR/Cas9 gene editing method for the correction of exon duplications in patients with DMD (Duchenne muscular dystrophy). This therapy has the potential to permanently corrects DMD by stopping and potentially reversing the progression of muscle wasting and fibrosis in affected individuals. Currently about 11% of DMD cases are caused by exon duplications and our experts plan to use this invention to correct for this underlying cause within muscle tissues.
