Oligonucleotide therapies for disorders of the nervous system

Abstract

Oligonucleotide therapies are currently experiencing a resurgence driven by advances in backbone chemistry and discoveries of novel therapeutic pathways that can be uniquely and efficiently modulated by the oligonucleotide drugs. A quarter of a century has passed since oligonucleotides were first applied in living mammalian brain to modulate gene expression. Despite challenges in delivery to the brain, multiple oligonucleotide-based compounds are now being developed for treatment of human brain disorders by direct delivery inside the blood brain barrier (BBB). Notably, the first new central nervous system (CNS)-targeted oligonucleotide-based drug (nusinersen/Spinraza) was approved by US Food and Drug Administration (FDA) in late 2016 and several other compounds are in advanced clinical trials. Human testing of brain-targeted oligonucleotides has highlighted unusual pharmacokinetic and pharmacodynamic properties of these compounds, including complex active uptake mechanisms, low systemic exposure, extremely long half-lives, accumulation and gradual release from subcellular depots. Further work on oligonucleotide uptake, development of formulations for delivery across the BBB and relevant disease biology studies are required for further optimization of the oligonucleotide drug development process for brain applications.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The blood-brain barrier prevents the transfer of most small-molecule drugs and macromolecules into the brain.

    “it prevents the transfer of most of small-molecule drugs and macromolecules (e.g., peptides, gene drugs, and protein drugs) into the brain (1–6).”

    From Neurotransmitter-derived lipidoids (NT-lipidoids) for enhanced brain delivery through intravenous injection (2020) · cites this paper as [5]

    The Abstract (page unavailable) says oligonucleotides do not readily cross the blood-brain barrier and that fewer than 1% of systemically delivered oligonucleotides reach the brain. “Assisted delivery and CNS targeting of ODNs” (page unavailable) also mentions small molecules with poor BBB permeability and intranasal delivery of peptides or proteins. The paper does not establish the broader claim that the BBB prevents transfer of most small-molecule drugs and macromolecules. (LLM, conf=0.84)

  • Treatment of central nervous system diseases is severely constrained by the blood-brain barrier.

    “The treatment of central nervous system (CNS) diseases, such as neurodegenerative disorders, brain tumors, brain infections, and stroke, is severely constrained by the blood-brain barrier (BBB) because it prevents the transfer of most of small-molecule drugs and macromolecules (e.g., peptides, gene drugs, and protein drugs) into the brain (1–6).”

    From Neurotransmitter-derived lipidoids (NT-lipidoids) for enhanced brain delivery through intravenous injection (2020) · cites this paper as [5]

    The paper’s introductory passage says that the BBB is a substantial obstacle to treating CNS disorders with oligonucleotides: fewer than 1% of systemically delivered oligonucleotides reach the brain. Its assisted-delivery discussion also mentions small molecules with poor BBB permeability, peptides, and proteins. It does not establish the citing sentence’s broader assertion that the BBB prevents most small-molecule drugs and macromolecules from entering the brain across the listed CNS diseases. (LLM, conf=0.84)

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.
