Silence-and-Replace Technology

The Silence-and-Replace technology platform is designed to produce a long-term restoration of normal gene function and is achieved by combining RNA interference (silence) with gene therapy (replace) in a single administration of a single viral vector construct. This approach is applicable to various genetic diseases, particularly autosomal dominant genetic disorders caused by nucleotide repeat expansion.

Many neurological and muscular diseases are known to result from the erroneous expression of a mutated gene. RNA interference (“RNAi”) has shown significant potential to silence the expression of these disease-associated genes. Commonly-used RNAi approaches, in which small interfering RNA (“siRNA”) is introduced directly into the cell, achieve only transient gene silencing and are limited by the requirement for repeated administration and variable concentrations of siRNA over time. To provide lasting gene silencing, the Silence-and-Replace technology employs ddRNAi, in which viral vectors deliver a DNA construct that produces short hairpin RNAs (“shRNAs”), which are processed by the cell into siRNAs, which then silence the mutated genes.

In an autosomal dominant genetic disorder, particularly one caused by nucleotide repeat expansion, silencing of the mutant gene can also lead to silencing of the wild type gene which may be required for normal function. The Silence-and-Replace strategy is designed to address this potential issue by delivering a functional copy of the gene that is re-engineered to be resistant to knockdown. The gene that encodes the functional protein is contained within the same viral vector as the ddRNAi construct.

AXO-AAV-OPMD Program

The AXO-AAV-OPMD Program is an investigational gene therapy being developed as a one-time treatment for OPMD. The Program utilizes an AAV vector to silence the mutant poly-A binding protein N1 (“PABPN1”) gene that causes OPMD and replace with a functional copy of the PABPN1 gene. The Silence-and-Replace approach aims to knock down the expression of the mutant PABPN1 gene through ddRNAi, while at the same time express a re-engineered copy of the PABPN1 gene coding for the functional PABPN1 protein. The gene therapy will be delivered in a single administration directly into target muscle tissue to provide long-term correction of muscle pathology and restoration of function. Depending on the type of AAV vector that we decide to commercialize, it may be necessary for us to use the patented or proprietary technology of one or more third parties to commercialize AXO-AAV-OPMD. If we are unable to use these technologies or obtain licenses from these third parties when needed or on commercially reasonable terms, our ability to commercialize AXO-AAV-OPMD, if approved, would likely be delayed.

Data from mouse models of OPMD showed gene therapy from the AXO-AAV-OPMD Program provided up to 86% inhibition of PABPN1 expression, while restoring functional PABPN1 up to 63% of normal levels. The A17 mouse model is a well validated in vivo model that is designed to exhibit many of the key pathological features of OPMD patients. The levels of gene silencing and expression achieved in this model coincided with decreased muscle pathology and a restoration of muscle force and muscle weight to near wild-type levels.

We expect to initiate a placebo-controlled clinical study for the investigational AXO-AAV-OPMD Program in 2019. The U.S. Food& Drug Administration and European Commission have granted Orphan Drug Designation to the AXO-AAV-OPMD Program for the treatment of OPMD.

Oculopharyngeal Muscular Dystrophy

OPMD is a muscular disease that is inherited through a primarily autosomal dominant pattern. OPMD is estimated to affect approximately 15,000 people in North America and Europe. The disease generally presents between the ages of 40-70 years old and is characterized primarily by progressive swallowing difficulty (dysphagia), eyelid drooping (ptosis), and weakness of the proximal extremities. Swallowing difficulties can have life-threating consequences, including malnutrition and aspiration pneumonia. As the disease progresses, the dysphagia becomes more severe and other muscles may become involved. There are no products approved for the treatment of OPMD and therefore, treatment options available to patients are limited.

OPMD is caused by mutations in the gene coding for PABPN1, a ubiquitously expressed protein that regulates the processing of messenger RNAs. The normal PABPN1 protein contains ten copies of the amino acid alanine, which forms a polyalanine tract. In OPMD, the mutated PABPN1 gene has an expansion of alanine-encoding trinucleotide repeats, resulting in an abnormally long polyalanine tract. The protein that forms from the mutated gene is prone to aggregating into insoluble nuclear inclusion bodies which leads to muscle cell pathology and disease progression.

Additional Research Programs

Under our research and development collaboration with Benitec, we will pursue five additional investigational gene therapy research plans as part of Collaboration Programs focused on genetic neurological disorders utilizing Benitec’s technologies. We plan to initiate a research plan to develop gene therapy products targeting the C9orf72 gene which is associated with amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”). In addition, we plan to initiate four other research plans focused on undisclosed genetic neurological disorders.

ALS and FTD are neurological disorders that have been linked to hexanucleotide repeats in the C9orf72 gene. Thirty to forty percent of familial ALS cases are associated with C9orf72 mutations and these patients have a progressive muscle weakness resulting from the death of motor neurons in the spinal cord and brain. Patients with FTD associated with C9orf72 mutations have a progressive brain disorder that affects personality, behavior, language and movement. While the exact role of C9orf72 mutation is unknown, both expression of the mutated C9orf72 and lack of functional C9orf72 are believed to be implicated. We believe Silence-and-Replace gene therapy is a promising approach for the restoration of normal C9orf72 function and has the potential to deliver lasting benefits for ALS and FTD patients.
