• Status: Active, not recruiting
• Trial end date: 2025-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This randomized phase II trial studies how well lose dose bevacizumab with Hypofractionated Stereotactic Radiotherapy (HSRT) works versus bevacizumab alone in treating patients with glioblastoma at first recurrence. The primary endpoint is 6-month progress-free survivaloverall survival after the treatment. Secondary endpoints included overall survival, objective response rate, cognitive function, quality of life and toxicity.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
