Abstract

Panitumumab is a monoclonal antibody developed against the human epidermal growth factor receptor (EGFR).TAS‐102 is a novel chemotherapeutic agent containing trifluridine (FTD) as the active cytotoxic component. Both panitumumab and TAS‐102 have been approved for the treatment of metastatic colorectal cancer. In this study, we revealed the mechanism underlying the anticancer effects of panitumumab/TAS‐102 combination using preclinical models. Panitumumab/FTD cotreatment showed additive antiproliferative effects in LIM 1215 and synergistic antiproliferative effects in SW 48 colon cancer cells. Consistent with the in vitro effects, panitumumab/TAS‐102 combination caused tumor regression in LIM 1215 and COL‐01‐JCK colon cancer patient‐derived xenograft models. In LIM 1215 cells,FTD induced extracellular signal‐regulated kinase (ERK)/protein kinase B (AKT)/signal transducer and activator of transcription 3 (STAT 3) phosphorylation and subsequent serine/threonine phosphorylation of EGFR, while it had no effects on EGFR tyrosine phosphorylation. Panitumumab and the tyrosine kinase inhibitor erlotinib reduced the basal level of EGFR tyrosine phosphorylation and reversed FTD‐induced ERK/AKT/STAT 3 and EGFR serine/threonine phosphorylation. These results suggested that FTD in combination with the basal activity of EGFR tyrosine kinase induced downstream prosurvival signaling through ERK/AKT/STAT 3 phosphorylation. Collectively, we propose that panitumumab interacts with FTD by targeting EGFR‐mediated adaptive responses, thereby exerting anticancer effects when used in combination with TAS‐102. These preclinical findings provide a compelling rationale for evaluating the combination of anti‐EGFR antibodies with TAS‐102 against metastatic colorectal cancer.

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.
