NCT05235737

Brief Summary

To evaluate the short-term and longer-term safety, tolerability, and effectiveness of neoadjuvant and adjuvant Pembrolizumab on top of standard therapy (Stupp protocol) in patients with Glioblastoma Multiforme (GBM). Randomized comparison of safety, tolerability, and clinical efficacy of (1) neoadjuvant and adjuvant Pembrolizumab (on top of Stupp protocol, n=12 patients), (2) neoadjuvant Pembrolizumab (on top of Stupp protocol, n=12 patients), and (3) standard of care (Stupp protocol only, n=12 patients). Immuno-PET examination will be performed before and after surgery in all patients.

Secondary Outcomes (1)

  • Time-to-progression

    3 years after initial tumor surgery

Other Outcomes (1)
