Abstract: The present disclosure relates to compositions, methods and processes for the formulation and for the administration of a gene therapy agent using parvovirus e.g., adeno-associated virus (AAV) to the CNS, CNS tissues, CNS structures or CNS cells.

Abstract: The invention relates to compositions and methods for the preparation, administration, manufacture and therapeutic use of viral particles for the treatment of CNS disorders.

Abstract: The invention relates to compositions and methods for the preparation, manufacture and therapeutic use of polynucleotides encoding payloads for the treatment of CNS disorders.

Abstract: This invention provides treatment compositions as well as systems and methods of determining and administering an effective amount of treatment for a neurological disorder. The treatment composition can contain a labeled interfering RNA (iRNA) agent capable of decreasing expression of a target RNA associated with the neurological disorder. The methods of the invention include determining an effective amount of a therapeutic composition by introducing a solution containing a tracer into the brain of a mammal. The tracing solution is monitored until a target volume of distribution at steady state distribution is substantially achieved, and the rate of delivery of the therapeutic composition is determined. The therapeutic composition can then be administered at the rate determined by use of the tracing solution.

Abstract: Methods of treating disorders affecting the central nervous system (CNS) are disclosed. More particularly, methods of treating neurological disorders are disclosed which show therapeutic or prophylactic treatment of a mammalian CNS disorder by effecting local administration of an iRNA agent, followed by retrograde transport of the iRNA agent away from the administration site and onto multiple regions within the CNS. This retrograde transport of iRNA results in an improved therapeutic involvement for the respective iRNA agent.
