Abstract

Neurological disorders - disorders of the brain, spine and associated nerves - are a leading contributor to global disease burden with a shockingly large associated economic cost. Various treatment approaches - pharmaceutical medication, device-based therapy, physiotherapy, surgical intervention, among others - have been explored to alleviate the resulting extent of human suffering. In recent years, gene therapy using viral vectors - encoding a therapeutic gene or inhibitory RNA into a "gutted" viral capsid and supplying it to the nervous system - has emerged as a clinically viable option for therapy of brain disorders. In this Review, we provide an overview of the current state and advances in the field of viral vector-mediated gene therapy for neurological disorders. Vector tools and delivery methods have evolved considerably over recent years, with the goal of providing greater and safer genetic access to the central nervous system. Better etiological understanding of brain disorders has concurrently led to identification of improved therapeutic targets. We focus on the vector technology, as well as preclinical and clinical progress made thus far for brain cancer and various neurodegenerative and neurometabolic disorders, and point out the challenges and limitations that accompany this new medical modality. Finally, we explore the directions that neurological gene therapy is likely to evolve towards in the future. This article is part of the Special Issue entitled "Beyond small molecules for neurological disorders".

  • AAV vector administration to the CNS has an excellent safety and efficacy profile.

    “AAV vector administration to the CNS has an excellent safety and efficacy profile.”

    From AAVrh.10-Mediated APOE2 Central Nervous System Gene Therapy for APOE4-Associated Alzheimer's Disease (2018) · cites this paper as [52]

    Section 2 describes AAV vectors as close to ideal for CNS gene therapy, citing low toxicity and mild immunogenicity. But section 4.1 reports that clinical trials were less effective, with no significant improvement in one trial and only minor improvement in another. The paper supports a favorable safety profile, but not a generally excellent clinical efficacy profile. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • The AAV gene packaging size is limited to a maximum of 5.0 kb.

    “Although the gene packaging size is limited (maximum 5.0 kb), typically the relevant gene coding sequences can be easily packaged for CNS delivery.”

    From AAVrh.10-Mediated APOE2 Central Nervous System Gene Therapy for APOE4-Associated Alzheimer's Disease (2018) · cites this paper as [52]

    Sections 1 and 2 confirm that AAV packaging capacity is limited, but they give a maximum of about 4.5 kb, not 5.0 kb. Section 2 further specifies 4.5 kb for single-stranded vectors and 2.4 kb for self-complementary vectors. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The AAV serotypes most commonly used for clinical trials to date are AAV5, AAV9, and AAVrh.10.

    “Of these AAV serotypes, the most commonly used for clinical trials to date are AAV5, AAV9, and AAVrh.10.”

    From AAVrh.10-Mediated APOE2 Central Nervous System Gene Therapy for APOE4-Associated Alzheimer's Disease (2018) · cites this paper as [52]

    Section 4.1 identifies AAV9 and AAVrh10 as capsids used in more recent clinical trials. It does not identify AAV5 as commonly used in trials or establish that these three are the most commonly used serotypes; Section 3.1 discusses AAV5's cell-transduction pattern instead. The paper also says AAV2 was used in all first-generation trials. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • AAV vector-mediated gene therapy has become a preferred method for delivering therapeutic genes to the CNS.

    “AAV vector-mediated gene therapy has become a preferred method for delivering therapeutic genes to the CNS.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
