- Conditions
- Recurrent Glioblastoma
- Interventions
- Registration Number
- NCT05191784
- Lead Sponsor
- Genexine, Inc.
- Brief Summary
The purpose of this study is to evaluate the efficacy and safety of GX-I7 in combination with bevacizumab in subjects with recurrent glioblastoma.
- Detailed Description
This is a phase 2 study designed to evaluate the efficacy and safety of GX-I7 in combination with bevacizumab in subjects with recurrent glioblastoma.
A total of 20 patients will be enrolled in the study and administered bevacizumab GX-I7. The study treatment will be continued for up to 6 cycles or until a progression of disease or unacceptable toxicity is confirmed.
