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.

TS-000208 — Ninety percent of cases of amyotrophic lateral sclerosis (ALS) are sporadic and lack a familial association, but the etiology of sporadic ALS remains largely unknown. The laboratory of Dr. Brian Kaspar at Nationwide Children’s Hospital has discovered that overexpression of the HLA-F MHC class I molecule in motor neurons is protective against ALS. Further, they have identified a pharmaceutical composition that increases the expression of HLA-F in motor neurons and would serve as a treatment option for patients with both sporadic and familial ALS.

TS-000178 — A novel mouse model for testing exon skipping therapies for DMD disease has been generated at Nationwide Children’s Hospital. This mouse model carries a duplicated exon (exon2) in the DMD gene as compared to a point mutation in the most common mdx mouse model. This unique dystrophic mouse can serve as a preclinical testing model to test various therapies that mediate exon skipping.

TS-000149 — ALS, commonly referred to as Lou Gehrig’s disease, is characterized by selective, premature degeneration and death of motor neurons (MNs) in the motor cortex, brain stem and spinal cord. Studies have demonstrated that not only MNs but also non-neuronal cell types including microglia and astrocytes play a significant role in disease onset and progression. Researchers at Nationwide Children’s Hospital have identified a previously undescribed disease mechanism in which astrocytes use killing pathways typically ascribed to the innate immune system, and can use these mechanisms as targets for therapeutic intervention in ALS.
