Laser and immunotherapy combo takes on recurrent brain tumors

NCT ID NCT03277638

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

Summary

This study tests a combination of laser heat therapy (LITT) and the immunotherapy drug pembrolizumab in 32 adults with recurrent glioblastoma, an aggressive brain cancer. The laser heats and destroys hard-to-reach tumors, while pembrolizumab helps the immune system fight cancer cells. Researchers aim to find the best timing for the two treatments and measure tumor response and survival.

What this could mean

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

Active substance

Pembrolizumab (an immunotherapy drug) and Laser Interstitial Thermotherapy (a laser heat procedure)

What this could lead to

If successful, this combination could offer a new treatment option for recurrent glioblastoma, potentially improving tumor control and extending survival.

What could go wrong

This is an early-phase trial with only 32 participants, so results may not apply broadly. The drug is experimental for this use, and side effects from both the procedure and immunotherapy can be serious.
