Gene therapy takes on deadly brain tumors in new trial

NCT ID NCT03596086

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

Summary

This study tests a gene therapy (HSV-tk) plus valacyclovir, along with radiation and chemotherapy, in people whose glioblastoma or high-grade astrocytoma has returned. The goal is to see if this combination can improve survival. About 62 participants will receive the treatment directly into the tumor site during surgery, followed by standard therapies.

What this could mean

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

Active substance
gene therapy (HSV-tk) plus valacyclovir
What this could lead to
If successful, this could offer a new treatment option that extends survival for people with recurrent glioblastoma, a brain cancer with few effective therapies.
What could go wrong
This is an early-phase trial with only 62 participants, so results may not apply to everyone. Gene therapy carries risks like inflammation or infection, and the combination with radiation and chemo may cause significant side effects.
