Brain cancer vaccine trial aims to boost Chemo's punch
NCT ID NCT07365280
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase II trial tests a personalized dendritic cell vaccine (ZSNeo-DC1.1) combined with standard chemotherapy (temozolomide) in 78 adults with newly diagnosed glioblastoma. Participants receive the vaccine as shots during chemo after surgery and radiation. The goal is to see if the combo improves how long the cancer stays under control compared to chemo alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- personalized dendritic cell vaccine (ZSNeo-DC1.1) plus temozolomide chemotherapy
- What this could lead to
- If it works, this could offer a new way to extend survival for people with glioblastoma, a tough-to-treat brain cancer.
- What could go wrong
- This is a small, early-phase trial (78 people) with no results yet. The vaccine is personalized, which is complex, and it may not improve outcomes or could cause side effects.
