Could your own immune cells fight brain tumors? new trial tests lifileucel
NCT ID NCT05640193
First seen Jun 26, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
This early-phase trial is testing a personalized cell therapy called lifileucel in 10 people with melanoma that has spread to the brain and is no longer responding to standard immunotherapy. Doctors remove a piece of the tumor, grow the patient's own immune cells in the lab, and then infuse them back after a short course of chemotherapy. The main goal is to see if this approach is feasible and safe in this specific group of patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lifileucel (a personalized cell therapy made from the patient's own tumor-fighting immune cells)
- What this could lead to
- If it works, this could offer a new treatment option for melanoma that has spread to the brain and stopped responding to standard immunotherapy.
- What could go wrong
- This is a very early, small pilot trial with only 10 participants, so results may not apply broadly. The therapy involves surgery and strong chemotherapy, which carry serious risks.
