Abstract

In the 10 years that have passed since the Nobel prize-winning discovery of RNA interference (RNAi), billions of dollars have been invested in the therapeutic application of gene silencing in humans. Today, there are promising data from ongoing clinical trials for the treatment of age-related macular degeneration and respiratory syncytial virus. Despite these early successes, however, the widespread use of RNAi therapeutics for disease prevention and treatment requires the development of clinically suitable, safe and effective drug delivery vehicles. Here, we provide an update on the progress of RNAi therapeutics and highlight novel synthetic materials for the encapsulation and intracellular delivery of nucleic acids.

  • Recently, there has been an exponential growth in the development of clinically suitable nonviral delivery systems for siRNA.

    “Recently, there has been an exponential growth in the development of clinically suitable nonviral delivery systems for siRNA (19,20); we have taken advantage of these innovations to develop the LNP/RNA formulation and have now embarked on a more extensive evaluation of other nonviral delivery systems.”

    From Nonviral delivery of self-amplifying RNA vaccines (2012) · cites this paper as [20]

    The Main section describes advances in synthetic nonviral siRNA carriers and reports that some delivery agents are being used in clinical trials. It does not establish exponential growth, and it says safe, effective delivery remains a barrier rather than characterizing these systems generally as clinically suitable. Page numbers were not provided in our copy. (LLM, conf=0.85)

  • There are limited published data on the in vivo delivery of self-amplifying RNA using nonviral delivery strategies, and none has taken advantage of the recently developed, clinically suitable delivery systems for siRNA.

    “There are limited published data on the in vivo delivery of self-amplifying RNA using nonviral delivery strategies (3,14,18), and none has taken advantage of the recently developed, clinically suitable delivery systems for siRNA (19,20).”

  • Cell penetrating peptides can damage or rebuild endosomal membranes to enhance intracellular delivery of nucleic acids.

    “Additionally, endosomal membranes have been damaged or rebuilt using cell penetrating peptides to enhance the intracellular delivery of nucleic acids.313”

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.
