Durable clinical and immunologic response to an off-the-shelf EWSR1-FLI1 peptide vaccine in metastatic Ewing sarcoma.

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
Ewing sarcoma is a rare, fusion-driven malignancy with poor prognosis in the metastatic setting, for which no established immunotherapeutic treatment is currently available. Fusion breakpoints are rational precision immunotherapy targets, yet clinical evidence of immunogenicity is scarce. We administered an off-the-shelf multi-peptide vaccine spanning the type 1 EWSR1-FLI1 breakpoint to a patient with high-burden metastatic Ewing sarcoma following multimodal therapy. Vaccinations were combined with GM-CSF and topical imiquimod. Longitudinal immune monitoring by in vitro peptide stimulation and intracellular cytokine staining revealed de novo polyfunctional CD4⁺ T-cell responses against all four fusion-derived peptides, first detectable by month 7 and persisting beyond two years. Treatment was well tolerated with only grade 1 local reactions. Durable disease stability was maintained for more than 26 months. These first-in-human data support the feasibility, safety, and immunogenicity of a fusion-derived peptide vaccine and warrant further evaluation of precision immunotherapy in sarcomas driven by recurrent gene fusions.
