EGFR blocker lapatinib inhibits the synthesis of matrix metalloproteinases from synovial fibroblasts.

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.
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
backgroundEpidermal growth factor receptor (EGFR) family members and their associated ligands may be related to bone and joint destruction in rheumatoid arthritis. Matrix metalloproteinases are responsible for joint and bone tissue degradation. This study is intended to investigate the effect of epidermal growth factor receptor inhibition by lapatinib on the synthesis of matrix metalloproteinases in in vitro.
methodsSynovial fibroblast cell culture was obtained from a patient with rheumatoid arthritis who underwent knee arthroplasty. Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were added to the cell culture to stimulate synovial fibroblast cells and create an inflammatory character. Understimulated and nonstimulated conditions, lapatinib was applied to the culture in four different concentrations of 25, 50, 100, and 200 µmol. Then, matrix metalloproteinase -1, -3, and, -13 levels were assessed.
resultsWhen stimulated with IL-1β and TNF-α, the synthesis of matrix metalloproteinases from synovial fibroblast was increased significantly. When lapatinib is added to the stimulated synovial fibroblasts, matrix metalloproteinases synthesis is significantly suppressed. DISCUSSION: Inhibition of the EGFR pathway with lapatinib suppresses matrix metalloproteinases synthesis. Our results suggest EGFR pathway inhibition may be a promising option to prevent joint destruction in the treatment of rheumatoid arthritis.
