New preclinical data help further characterize the potential efficacy profile of SGT-001.
AAV Micro-Dystrophin Therapy Ameliorates Muscular Dystrophy in Young Adult Duchenne Muscular Dystrophy Dogs for Up to Thirty Months Following Injection
Oral presentation: abstract #8
Long-term preclinical data in canines demonstrated that a single intravenous administration of a low, medium or high dose of SGT-001 resulted in body-wide microdystrophin transgene expression, as well as restoration of key microdystrophin-associated proteins, including neuronal nitric oxide synthase (nNOS). This expression, which was sustained for at least 30 months, was associated with reduced muscle pathology and improved muscle function. These data were presented by Solid’s collaborators at the

Additional preclinical data presented by the
Preclinical Evaluation of SGT-001 Microdystrophin Gene Transfer for Duchenne Muscular Dystrophy
Poster presentation: abstract #854
New preclinical data evaluating the relationship of SGT-001 and nNOS demonstrated that a dose-dependent increase in nNOS protein expression and associated nNOS activity corresponded with microdystrophin expression. This resulted in improvements in muscle histopathology and muscle function in both small and large animal models, suggesting nNOS activity could serve as a marker of molecular function.

Solid’s lead candidate, SGT-001, is a novel adeno-associated viral (AAV) vector-mediated gene transfer under investigation for its ability to address the underlying genetic cause of DMD, mutations in the dystrophin gene that result in the absence or near-absence of dystrophin protein. SGT-001 is a systemically administered candidate that delivers a synthetic dystrophin transgene, called microdystrophin, to the body. This microdystrophin encodes for a functional protein surrogate that is expressed in muscles and stabilizes essential associated proteins, including neuronal nitric oxide synthase (nNOS). SGT-001 utilizes AAV9, which has an affinity for muscle and is currently being evaluated in multiple clinical programs in other indications. Data from Solid’s preclinical program suggests that SGT-001 has the potential to slow or stop the progression of DMD, regardless of genetic mutation or disease stage.
SGT-001 is based on pioneering research in dystrophin biology by Dr. Jeffrey Chamberlain of the University of Washington and Dr. Dongsheng Duan of the University of
