NCT ID NCT05096481

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial is testing a vaccine called PEP-CMV in 120 children and young adults with high-grade glioma, diffuse intrinsic pontine glioma (DIPG), or recurrent medulloblastoma. The vaccine targets a common virus (CMV) found in many brain tumors, aiming to boost the immune system to attack the cancer. Participants receive the vaccine along with standard treatments like radiation or chemotherapy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

PEP-CMV vaccine (a synthetic peptide targeting CMV antigen, mixed with Montanide ISA-51 adjuvant)

What this could lead to

If successful, this vaccine could offer a new immunotherapy option to help control aggressive pediatric brain tumors by training the immune system to attack cancer cells.

What could go wrong

This is an early Phase 2 trial with a small number of participants, so results may not apply to all patients. The vaccine may not shrink tumors or improve survival, and side effects from the immune response are possible.
