1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

To investigate the interactions of Epidermal Growth Factor Receptor (EGFR)-inhibiting tyrosine kinase inhibitors (TKIs) on P-gp-mediated drug resistance, we tested three TKIs, lapatinib, gefitinib and erlotinib in direct ATPase assays and in Non-Small Cell Lung Cancer (NCSLC) cell lines with defined low levels of growth factor receptor expression. The three TKIs potentiated the action of known P-gp substrate cytotoxic drugs at therapeutically-relevant concentrations. However, more detailed analysis revealed that the interaction of lapatinib with P-gp was distinct from that of gefitinib and erlotinib, and was characterised by direct inhibition of the stimulated P-gp ATPase activity. Lapatinib proved the most potent P-gp modulator of the TKIs examined. Drug transport studies in the P-gp-over-expressing A549-Taxol cell line showed that lapatinib and erlotinib are capable of increasing docetaxel accumulation at clinically achievable concentrations. Combination studies with P-gp substrate chemotherapeutic agents, demonstrated that all three TKIs have significant potential to augment cytotoxic activity against P-gp-positive malignancies, however, interestingly, these agents also potentiated the toxicity of epirubicin in non-P-gp resistant parental cells. Our observations suggest that the combination of lapatinib with a taxane or anthracycline warrants clinical investigation in NSCLC to examine if beneficial or detrimental interactions may result.
