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

backgroundPersonalized immunotherapy of pancreatic ductal adenocarcinoma (PDAC) through T-cell mediated targeting of tumor-specific, mutanome-encoded neoepitopes may offer new opportunities to combat this disease, in particular by countering recurrence after primary tumor resection. However, the sensitive and accurate calling of somatic mutations in PDAC tissue samples is compromised by the low tumor cell content. Moreover, the repertoire of immunogenic neoepitopes in PDAC is limited due to the low mutational load of the majority of these tumors.

methodsWe developed a workflow involving the combined analysis of next-generation DNA and RNA sequencing data from matched pairs of primary tumor samples and patient-derived xenograft models towards the enhanced detection of driver mutations as well as single nucleotide variants encoding potentially immunogenic T-cell neoepitopes. Subsequently, we immunized HLA/human T-cell receptor (TCR) locus-transgenic mice with synthetic peptides representing candidate neoepitopes, and molecularly cloned the genes encoding TCRs targeting these epitopes.

resultApplication of our pipeline resulted in the identification of greater numbers of non-synonymous mutations encoding candidate neoepitopes with increased confidence. Furthermore, we provide proof of concept for the successful isolation of HLA-restricted TCRs from humanized mice immunized with different neoepitopes, several of which would not have been selected based on mutanome analysis of PDAC tissue samples alone. These TCRs mediate specific T-cell reactivity against the tumor cells in which the corresponding mutations were identified.

conclusionEnhanced mutanome analysis and candidate neoepitope selection increase the likelihood of identifying therapeutically relevant neoepitopes, and thereby support the optimization of personalized immunotherapy for PDAC and other poorly immunogenic cancers.
