Abstract

Drug repurposing or repositioning has been well-known to refer to the therapeutic applications of a drug for another indication other than it was originally approved for. Repurposing non-oncology small-molecule drugs has been increasingly becoming an attractive approach to improve cancer therapy, with potentially lower overall costs and shorter timelines. Several non-oncology drugs approved by FDA have been recently reported to treat different types of human cancers, with the aid of some new emerging technologies, such as omics sequencing and artificial intelligence to overcome the bottleneck of drug repurposing. Therefore, in this review, we focus on summarizing the therapeutic potential of non-oncology drugs, including cardiovascular drugs, microbiological drugs, small-molecule antibiotics, anti-viral drugs, anti-inflammatory drugs, anti-neurodegenerative drugs, antipsychotic drugs, antidepressants, and other drugs in human cancers. We also discuss their novel potential targets and relevant signaling pathways of these old non-oncology drugs in cancer therapies. Taken together, these inspiring findings will shed new light on repurposing more non-oncology small-molecule drugs with their intricate molecular mechanisms for future cancer drug discovery.

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

  • It takes 10-15 years and costs $1-2 billion to produce a new drug approved for clinical use.

    “As such, it takes 10–15 years and costs $1–2 billion to produce a new drug approved for clinical use.”

    From Drug repurposing for cancer therapy (2024) · cites this paper as [13]

    The Introduction reports that developing a new cancer drug takes an average of 10–17 years, close to the claimed 10–15 years. It gives a median cost of $648 million, however, not $1–2 billion; that higher figure approaches only the upper end of its reported cost range. The source also addresses cancer drugs rather than new drugs generally. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Less than 1% of compounds are expected to enter clinical trials, let alone reach the market.

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.
