Safety and Efficacy of TRPP Therapy in Glioblastoma Multiforme

The primary objective of this study is to evaluate the safety of an innovative integrated treatment regimen for recurrent glioblastoma , including patients with recurrent glioblastoma multiforme.

This study is a single-center, prospective, open-label, single-arm clinical study of an innovative integrated treatment regimen for recurrent glioblastoma multiforme.

The main outcome measurement of the study is to evaluate the safety of the integrated treatment regimen for glioblastoma multiforme. Secondary outcome measurement are OS, PFS, ORR, and quality of life. Safety is evaluated by monitoring adverse events, physical examination results, vital signs, ECG, hematology, and clinical biochemistry. Imaging was performed at the end of every 3 sessions to assess treatment outcome and disease progression. The whole treatment and efficacy will be observed for two years.

Eligibility Criteria:
Inclusion Criteria:
