Can we predict who will respond to melanoma immunotherapy?
NCT ID NCT07407166
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is tracking 40 people in Slovenia with metastatic melanoma who are receiving standard first-line immunotherapy. Researchers want to see how well the treatment works and look for clues in blood, stool, and tumor samples that might predict who will benefit most. The goal is to improve personalized treatment for advanced melanoma.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Immunotherapy (immune checkpoint inhibitors, such as anti-PD-1 with or without anti-CTLA-4)
- What this could lead to
- If successful, this could help doctors better predict which patients with metastatic melanoma will benefit from immunotherapy, leading to more personalized treatment plans.
- What could go wrong
- This is an observational study with only 40 participants, so results may not apply to everyone. It is not testing a new treatment, just gathering data on standard care.
