Custom-Made brain cancer vaccine shows promise in early trial

NCT ID NCT02287428

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This early-phase trial tests a personalized vaccine (NeoVax) made from each patient's unique tumor mutations, combined with radiation and the immunotherapy drug pembrolizumab (Keytruda), in people with newly diagnosed glioblastoma. The main goals are to see if the vaccine can be made safely and to check for side effects. About 56 participants are enrolled across several groups, some also receiving standard chemotherapy. The study is not yet recruiting and is actively following patients.

What this could mean

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

Active substance
Personalized neoantigen vaccine (NeoVax) plus pembrolizumab (Keytruda) and radiation therapy
What this could lead to
If successful, this could point toward a new treatment approach that uses a patient's own tumor mutations to train the immune system to fight glioblastoma, potentially delaying recurrence.
What could go wrong
This is an early phase 1 trial with only 56 participants, focused on safety and feasibility. The vaccine is personalized and complex to produce, and it is not yet proven to work. Adding immunotherapy may increase side effects.
