We are a gene therapy company leveraging breakthroughs in human genetics with the goal of developing and commercializing disease-modifying AAV-based gene therapies for patients with devastating neurodegenerative diseases. We are applying a precision medicine approach to neurodegeneration by studying our gene therapies in genetically defined patient populations. We believe this will increase the probability of creating disease-modifying therapies that improve patients’ lives.

Our lead program is PR001 for the treatment of Parkinson’s disease with GBA1 mutation, or PD-GBA, and neuronopathic Gaucher disease. We are focused on developing a broad pipeline of gene therapies for a range of neurodegenerative diseases, including PR006 for the treatment of frontotemporal dementia with GRN mutation and PR004 for the treatment of synucleinopathies.

Our differentiated approach to developing gene therapies for neurodegenerative diseases is designed to mitigate challenges faced by others in the development of therapeutics for the central nervous system, or CNS. We select targets for diseases that correspond to patient populations with particular genetic mutations whom we believe can be treated by increasing or decreasing the expression of a particular gene, which makes them well-suited for gene therapy. We apply our deep understanding of human genetics to design our gene therapy product candidates, each of which is intended to be a one-time treatment to address the key underlying genetic mutation that we believe drives disease progression.

We are developing our lead program, PR001, to treat patients with PD-GBA and neuronopathic Gaucher disease. PD-GBA affects 7% to 10% of the total Parkinson’s disease population worldwide and an estimated 90,000 individuals in the United States alone. Gaucher disease is among the most common lysosomal storage disorders, with an estimated global prevalence of one per 30,000 to one per 100,000. Neuronopathic Gaucher disease patients exhibit neurological manifestations in addition to the non-CNS manifestations of Gaucher disease, and represent approximately 6% of all Gaucher disease cases in the United States.
