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

Pancreatic ductal adenocarcinoma (PDAC) represents an immune quiescent tumor that is resistant to immune checkpoint inhibitors. Previously, our group has shown that a GM-CSF-secreting allogenic pancreatic tumor cell vaccine (GVAX) may prime the tumor microenvironment by inducing intratumoral T cell infiltration. Here, we show that untreated PDACs express minimal indoleamine-2,3-dioxygenase (IDO1); however, GVAX therapy induced IDO1 expression on tumor epithelia as well as vaccine-induced tertiary lymphoid aggregates. IDO1 expression plays a role in regulating the polarization of Th1, Th17, and possibly T regulatory cells in PDAC tumors. IDO1 inhibitor enhanced antitumor efficacy of GVAX in a murine model of PDACs. The combination of vaccine and IDO1 inhibitor enhanced intratumoral T cell infiltration and function, but adding anti-PD-L1 antibody to the combination did not offer further synergy and in fact may have had a negative interaction, decreasing the number of intratumoral effector T cells. Additionally, IDO1 inhibitor in the presence of vaccine therapy did not significantly modulate intratumoral myeloid-derived suppressor cells quantitatively, but diminished their suppressive effect on CD8+ proliferation. Our study supports the combination of IDO1 inhibitor and vaccine therapy; however, it does not support the combination of IDO1 inhibitor and anti-PD-1/PD-L1 antibody for T cell-inflamed tumors such as PDACs treated with vaccine therapy.
