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

backgroundEpidermal growth factor receptor (EGFR) mutations represent one of the most frequent oncogenic driver in non-small cell lung cancer (NSCLC). Amivantamab, a bispecific antibody targeting EGFR and MET proto-oncogene, receptor tyrosine kinase (MET), has demonstrated clinical benefit in EGFR-mutant NSCLC through dual blockade, but its immunological role in human clinical specimens, especially tumor-infiltrating lymphocytes (TILs), has not been directly evaluated.

methodsWe analyzed surgically resected tumor samples from 40 patients with NSCLC to investigate immune responses and their associations with EGFR and MET expression. TILs were characterized by flow cytometry (FCM) and immunohistochemistry (IHC). To assess the immunomodulatory potential of amivantamab, fresh tumor digests containing live tumor cells and TILs were cultured ex vivo with CD3 and CD28 stimulation in the absence or presence of amivantamab, followed by FCM. EGFR and MET expression were also evaluated by IHC.

resultsEGFR mutations and high EGFR protein expression were associated with a trend toward reduced CD8⁺ T-cell and dendritic cell (DC) infiltration. In ex vivo TIL assays, exposure to amivantamab significantly activated CD8⁺ T cells, such as programmed cell death-1 expression and cytokine production, and promoted DC maturation. These effects were most pronounced in tumors with high EGFR or MET protein expression rather than EGFR mutations.

conclusionsThis study provides the first direct evidence from ex vivo fresh TIL assays using human NSCLC clinical specimens that amivantamab can activate immune responses. EGFR and MET expression may serve as potential biomarkers for amivantamab-induced immune responses.
