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

backgroundNeomorphic isocitrate dehydrogenase (IDH) mutations lead to the accumulation of 2-hydroxyglutarate (2-HG), an oncometabolite implicated in tumor progression via inhibitory effects on alpha-ketoglutarate. Moreover, mutant IDH-dependent accumulation of 2-HG results in homologous recombination deficiency (HRD), which preclinically renders tumors sensitive to poly(adenosine diphosphate ribose) polymerase inhibitors. Here, the results of the cholangiocarcinoma (CCA) arm of the National Cancer Institute (NCI) 10129 olaparib in IDH-mutant solid tumors basket trial are reported.

methodsOlaparib 300 mg twice daily was evaluated in an open-label, phase 2 clinical trial for treatment-refractory IDH-mutant solid tumors. Patients in the IDH-mutant CCA arm enrolled in two cohorts: (1) IDH inhibitor (IDHi) pretreated and (2) IDHi untreated, with a primary end point of overall response rate.

resultsNCI 10129 enrolled 30 patients with IDH-mutant CCA with no objective responses seen, and recruitment was closed early. Median progression-free survival (PFS) was 2.4 months (95% CI, 1.9 to 6.5 months) and median overall survival was 12.9 months (95% CI, 6.3 months to not reached). Eight patients (27%) had clinical benefit (CB), with a PFS of ≥6 months. Patients with CB had lower baseline 2-HG levels compared to those without CB (1.4 vs. 5.9 µmol/L; p = .01).

conclusionsOlaparib does not have sufficient single-agent activity to warrant further development in IDH-mutant CCA. However, a subgroup of patients demonstrated CB, and exploratory analysis revealed this subgroup to be enriched for lower baseline 2-HG levels. Future clinical trials leveraging the HRD properties of IDH mutations are warranted with enhanced patient selection and novel combination therapies.
