Clinical Trial Summary

To investigate the efficacy, safety and tolerability of superselective cerebral arterial infusion of Bevacizumab combined with intrathecal injection of Tislelizumab in the treatment of recurrent glioblastoma

Description:

Glioblastoma multiforme (GBM) is a highly malignant intracranial tumor with a median survival of only about 15-17 months after standard treatment. Patients with GBM often experience disease recurrence, and once recurrence occurs, treatment options are very limited, with a median overall survival of only about 6 months. Results of a phase II clinical trial of nivolumab combined with standard or reduced-dose bevacizumab iv therapy for recurrent GBM showed that the median PFS for the two groups was 5.6 months vs. 4.6 months, respectively. The aim of this study is to improve the outcome of recurrent GBM patients by changing the route of administration of the two drugs, such as delivering Bevacizumab via intra-arterial infusion and administering PD-1 monoclonal antibodies via intrathecal injection.

Intervention

Drug:
• Tislelizumab and Bevacizumab
Tislelizumab is a drug material authorized for marketing in China. Tislelizumab will be administered off-label in this study. Subjects with recurrent GBM will receive intrathecal tislelizumab every 3 weeks for six times. Intrathecal administration of Bevacizumab will be performed via Ommaya reservoir or intraventricular catheter.
