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

The goals of this investigation were to illustrate the use of pharmacokinetic (PK)/pharmacodynamic (PD) modeling strategies in drug development based on a multiple-dose study of gefitinib in a preclinical tumor model. Mice bearing s.c. LN229-wild-type epidermal growth factor receptor or LN229-EGFRvIII mutant (a sensitizing mutation) tumors were administered gefitinib at oral doses of either 55 mg/kg/d p.o. x 15 days or 30 mg/kg/d p.o. x 15 days, respectively, as dictated by the equivalent PK/PD dosing strategy. In each tumor group, gefitinib plasma and tumor concentrations were quantitated, as well as the tumoral amounts of phosphorylated-extracellular signal-regulated kinase 1/2 (pERK), a selected PD end point, and tumor size. The resultant data provided the basis to develop hybrid physiologically based PK/PD/tumor growth models for each tumor type. It was found that the 1.83-fold dose difference administered to the two tumor groups resulted in analogous pERK profiles on both days 1 and 15, and further induced similar antitumor efficacy based on tumor size. In addition, using brain tumor patient PK data linked to the pERK PD model, simulations were conducted to illustrate potential applications of a target tumor model to patients. The simulations provided insight on the relationships between blood-brain barrier penetration, brain tumor gefitinib concentrations, and the extent of inhibition of pERK. The implementation of the PK/PD equivalent dosing strategy offers a new approach to drug development.
