Abstract

Resistance to current therapies is common for pancreatic cancer and hence novel treatment options are urgently needed. In this work, we developed and validated a computational method to select synergistic compound combinations based on transcriptomic profiles from both the disease and compound side, combined with a pathway scoring system, which was then validated prospectively by testing 30 compounds (and their combinations) on PANC-1 cells. Some compounds selected as single agents showed lower GI50 values than the standard of care, gemcitabine. Compounds suggested as combination agents with standard therapy gemcitabine based on the best performing scoring system showed on average 2.82-5.18 times higher synergies compared to compounds that were predicted to be active as single agents. Examples of highly synergistic in vitro validated compound pairs include gemcitabine combined with Entinostat, thioridazine, loperamide, scriptaid and Saracatinib. Hence, the computational approach presented here was able to identify synergistic compound combinations against pancreatic cancer cells.

  • Combination therapies have proven to be an effective strategy for the management of PDAC.

    “Combination therapies have proven to be an effective strategy for the management of PDAC.”

    From Pyrvinium Pamoate Alone and With Gemcitabine Exhibits Anti‐Pancreatic Cancer Activity in <scp>2D</scp> and <scp>3D</scp> Cell Culture Models (2024) · cites this paper as [29]

    The Introduction (page not provided) says gemcitabine is used with nab-paclitaxel as a first-line treatment and that drug combinations have been studied to improve PDAC therapy. But it describes increased efficacy as a potential benefit, while this paper's demonstrated synergies are in pancreatic cancer cells; it does not establish that combination therapies have proven effective for clinical management of PDAC. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • By combining low doses of drugs with distinct mechanisms of action, drug resistance may be overcome, leading to increased efficacy with minimal or no side effects.

    “By combining low doses of drugs with distinct mechanisms of action, drug resistance may be overcome, leading to increased efficacy with minimal or no side effects [29]”

    From Pyrvinium Pamoate Alone and With Gemcitabine Exhibits Anti‐Pancreatic Cancer Activity in <scp>2D</scp> and <scp>3D</scp> Cell Culture Models (2024) · cites this paper as [29]

    The Results (Drug combination screening; page unavailable) report increased killing of pancreatic cancer cells with some low-dose drug combinations, and the Discussion reports synergy for gemcitabine combinations. The paper does not show that these combinations overcome drug resistance or produce minimal or no side effects; its efficacy tests were in cells, not patients. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Combining two drugs with different mechanisms of action and at lower doses may overcome drug resistance and lead to fewer side effects.

    “because combining two drugs with different mechanisms of action and at lower doses may overcome drug resistance and lead to fewer side effects [29].”

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.
