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

purposeTo describe a phase II study design to evaluate the activity of novel anti-cancer agents that focuses on molecular pathogenesis rather than tumor histology.

methodsWe propose an enrichment design that enrolls patients across histologies expressing target X and incorporates randomized discontinuation of drug Y after an initial treatment period to evaluate for potential cystostatic activity.

resultsWe are currently evaluating the activity of lapatinib in patients with HER-2 amplified solid tumors using the target-specific, histology-independent, randomized discontinuation design. Patients receive treatment with lapatinib for an initial 12-week period. After restaging, patients with disease progression are removed from study, patients achieving an objective response continue treatment, and patients with stable disease are randomized to continue lapatinib versus initiate treatment with placebo. The primary endpoints are to evaluate the objective response rate during the initial treatment period and to evaluate the proportion of patients progression-free 12 weeks post-randomization.

conclusionThe target-specific, histology-independent, randomized discontinuation design is an attractive alternative to the traditional phase II design for the development of "targeted" therapeutics.
