Abstract

Summary: Since identification of the CFTR gene over 25 years ago, gene therapy for cystic fibrosis (CF) has been actively developed. More recently gene therapy has been joined by other forms of “genetic medicines” including mRNA delivery, as well as genome editing and mRNA repair‐based strategies. Proof‐of‐concept that gene therapy can stabilize the progression of CF lung disease has recently been established in a Phase IIb trial. An early phase study to assess the safety and explore efficacy of CFTR mRNA repair is ongoing, while mRNA delivery and genome editing‐based strategies are currently at the pre‐clinical phase of development. This review has been written jointly by some of those involved in the various CF “genetic medicine” fields and will summarize the current state‐of‐the‐art, as well as discuss future developments. Where applicable, it highlights common problems faced by each of the strategies, and also tries to highlight where a specific strategy may have an advantage on the pathway to clinical translation. We hope that this review will contribute to the ongoing discussion about the hype versus reality of genetic medicine‐based treatment approaches in CF.

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

  • The main limitation of CF gene therapy based on delivery of a CFTR cDNA copy is the low and non-permanent CFTR expression obtained in the affected tissues.

    “The main limitation of this gene therapy strategy is the low and non-permanent CFTR expression obtained in the affected tissues7,53.”

    From Allele specific repair of splicing mutations in cystic fibrosis through AsCas12a genome editing (2019) · cites this paper as [7]

    In “Identification of Gene Transfer Agents Suitable for Clinical Translation Is Challenging” (page not specified), the review says immune responses limit the efficacy and duration of expression of adenoviral and AAV vectors. In “Alternative Gene Transfer Agents Suitable for CF Gene Therapy” (page not specified), it describes the non-viral vector GL67A as much less efficient than a lentiviral vector, but also reports long-lasting expression from lentiviral delivery in mouse lungs. Low efficiency and limited duration are therefore supported for some delivery methods, not as a blanket limitation of CFTR cDNA gene therapy. (LLM, conf=0.87)

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.
