Single center experience of IDH inhibitors in recurrent high-grade gliomas.
Article in Journal of neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe role of IDH inhibitors in recurrent high-grade gliomas (HGG) is not well described. We present the outcomes of patients with HGG that were treated with these agents at our institution.
methodsWe reviewed patients with recurrent IDH-mutant HGG treated with FDA approved IDH inhibitors (ivosidenib, enasidenib, and vorasidenib) from December 2019 to December 2024 at the University of Texas MD Anderson Cancer Center.
results23 patients were identified of which 65.2% were male. Tumors included astrocytoma (n = 14, 60.9%) and WHO grade 3 oligodendroglioma (n = 9, 39.1%), with four patients having a WHO grade 4 astrocytoma and 10 a WHO grade 3 astrocytoma. Twenty patients had enhancing disease at the time an IDH inhibitor was recommended. One patient was treated with enasidenib, 17 with ivosidenib, and 5 with vorasidenib. Of those initially treated with ivosidenib, 9 were switched to vorasidenib. Two patients discontinued the drugs due to side effects, that included elevated liver enzymes (n = 1), and diarrhea (n = 1). All patients had received prior surgery, radiation, and chemotherapy before starting an IDH inhibitor. Median overall survival (OS) was not reached. OS after IDH inhibitor was 20.7 months and was longer in patients that had not received initial chemotherapy (p = 0.032). Median progression-free survival (PFS) was 6.8 months and was not different between tumor type, sex, or number of recurrences, but was longer in patients that did not receive initial chemotherapy (p = 0.041).
conclusionIDH inhibitors were well tolerated in patients with IDH-mutant HGG previously treated with DNA-damaging agents. A median PFS longer than 6 months is encouraging in this patient population and may be due to antitumor activity of IDH inhibitors in recurrent HGG.
