Genetically modified t cells take on glioblastoma

NCT ID NCT06815432

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

Summary

This early-stage trial tests a new type of immunotherapy for recurrent glioblastoma, an aggressive brain cancer. Researchers take a patient's own T cells and genetically engineer them to recognize and attack cancer cells that carry a protein called GPC3. The cells also include a safety switch that can be activated to stop them if needed. The study aims to find a safe dose and see if the treatment can shrink tumors.

What this could mean

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

Active substance

GPC3-CAR T cells with IL15 and iCasp9 safety switch

What this could lead to

If it works, this could point toward a new treatment option for recurrent glioblastoma, a brain cancer with few effective therapies.

What could go wrong

This is an early Phase 1 trial with only 27 participants, focused on safety. The treatment may not shrink tumors or improve survival, and there are risks of serious side effects like cytokine release syndrome.
