Phase I Clinical Study of a Multi-Kinase Inhibitor TG02 Capsule for the Treatment of Recurrent High-Grade Gliomas with Failed Temozolomide Treatment in Chinese Patients. | LitMetric

AI Article Synopsis

Article Abstract

Introduction: We report the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of a multi-kinase inhibitor (TG02 capsule) as a new therapy for patients with recurrent high-grade gliomas in China.

Methods: This is a single-center, dose-escalation, open-label phase I study, which enrolled patients with recurrent high-grade gliomas who failed to temozolomide. Patients were assigned sequentially into different dose groups and received TG02 every 4 weeks. The dose was increased in a traditional 3 + 3 design. Primary endpoints were the dose-limited toxicity (DLT) and the maximum tolerated dose (MTD).

Results: Twelve patients (8 glioblastomas, 4 diffuse astrocytoma) were enrolled between May 2019 and November 2021. Three patients received 100 mg and 9 received 150 mg TG02 twice a week. The plasma concentration of TG02 reached the maximum at 2 h after administration, and the elimination half-life was about 7 h. No DLT occurred and MTD was not defined in this study. Eleven patients had one or more investigator-assessed treatment-related adverse events (TRAEs). The most frequent TRAEs were vomiting (91.7%) and diarrhea (75.0%), and 50% of the patients had grade 3 or 4 adverse events. There were no treatment-related deaths. The median progression-free survival and overall survival were 1.77 (95% confidence interval [CI]: 0.82-4.24) and 9.63 (95% CI: 2.66-not estimated) months, respectively.

Conclusions: TG02 capsule 150 mg twice a week is safe and tolerable in Chinese patients with recurrent high-grade gliomas. Patients who failed to temozolomide showed obvious tumor reduction when switching to TG02 capsule. The efficacy of recurrent gliomas warrants further investigation.
