A phase I/II trial of vandetanib for patients with recurrent malignant glioma.
Trial report in Neuro-oncology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 48 papers, 5 of them syntheses that pooled 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.
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
Vandetanib is a once-daily multitargeted tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, epidermal growth factor receptor, and the rearranged-during-transfection oncogene. A phase I trial was conducted to describe the pharmacokinetics of vandetanib in patients with recurrent glioma on enzyme-inducing anti-epileptic drugs (EIAEDs) and to identify the maximum tolerated dose (MTD) in this population. A phase II trial evaluated the efficacy of vandetanib in patients with recurrent malignant glioma not on EIAEDs as measured by 6-month progression-free survival (PFS6). In the phase I trial, 15 patients were treated with vandetanib at doses of 300, 400, and 500 mg/day, in a standard dose-escalation design. The MTD in patients on EIAEDs was 400 mg/day, and steady-state levels were similar to those measured in patients not on EIAEDs. Dose-limiting toxicities were prolonged QTc and thromboembolism. Thirty-two patients with recurrent glioblastoma multiforme (GBM) and 32 patients with recurrent anaplastic gliomas (AGs) were treated in the phase II trial, at a dosage of 300 mg/day on 28-day cycles. Six patients (4 GBM, 2 AG) had radiographic response. PFS6 was 6.5% in the GBM arm and 7.0% in the AG arm. Median overall survival was 6.3 months in the GBM arm and 7.6 months in the AG arm. Seizures were an unexpected toxicity of therapy. Vandetanib did not have significant activity in unselected patients with recurrent malignant glioma.
