A phase I/II study of tagraxofusp in Japanese patients with blastic plasmacytoid dendritic cell neoplasm.

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
Tagraxofusp (TAG), a first-in-class CD123-targeted therapy, is a recombinant fusion protein of human interleukin-3 conjugated to a truncated diphtheria toxin payload. Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive orphan hematologic cancer with a poor prognosis, and is derived from plasmacytoid dendritic cells that overexpress interleukin-3 receptor subunit alpha (IL3RA or CD123). This open-label phase I/II study evaluated the efficacy and safety of TAG in 11 Japanese BPDCN patients, of whom seven were treatment-naïve (TN) and four had relapsed/refractory (R/R) disease. In the phase I portion, seven patients (five TN, two R/R) were treated, and no dose-limiting toxicity was observed, with 12 μg/kg/day tolerated. In the phase II portion, four patients (two TN, two R/R) were treated. Among the seven TN BPDCN patients, the rate of complete response (CR) + clinical CR (CRc: CR with minimal residual skin abnormality) was 57.1% (90% confidence interval [CI], 22.5-87.1), and the lower limit of the 90% CI (22.5%) exceeded the pre-specified threshold of 10%. Common adverse events included increased alanine aminotransferase (81.8%) and aspartate aminotransferase (72.7%), hypoalbuminemia, hypokalemia, and capillary leak syndrome (54.5%). The results indicate that TAG was effective and had a manageable safety profile in Japanese BPDCN patients.
