About this trial

This is a Phase II trial to evaluate the safety, tolerability, efficacy, and PK/ pharmacodynamic profiles of MT027 injected via ICV in participants with recurrent or progressive IDH-wildtype glioblastoma (WHO 2021 CNS Grade 4), who have previously received standard of care (SOC) therapy.

Each participant will undergo screening, treatment (receiving MT027 at a dose of 3×10\^7 cells), safety follow-up, and long-term follow-up periods.

MT027 will be given via ICV injection on Day 1 \& Day 15 of the first 28-day cycle. If the participant does not experience any unacceptable toxicities and disease progress in the first cycle, additional treatment may be continued bi-weekly in a 28-day cycle (Days 1 \& Day 15 of the 28-day cycle) until intolerable toxicity, disease progression, withdrawal from the study, or death, whichever comes first. After the last dose, there will be a safety follow-up period lasting for 1 year and then a long-term follow-up up to 15 years.
