Can a simple blood test predict immunotherapy results for melanoma patients?
NCT ID NCT03348891
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study involved 60 people with advanced melanoma who were already scheduled to receive immunotherapy drugs. Researchers collected blood samples and, when possible, tumor samples before and during treatment to look for biological markers that might predict whether the treatment would work. The goal was to find clues that could help doctors choose the best therapy for each patient in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors predict which melanoma patients will benefit from specific immunotherapy combinations.
- What could go wrong
- This is an observational study, not a treatment trial. It may not find clear markers, and results may not change patient care directly.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥18 years at the time of study entry. 2. Patient with histologically-proven metastatic and/or unresectable melanoma (stage IIIc-IV, M1a-c as per AJCC 2009), including mucosal melanoma. 3. Patient for which a treatment with immune checkpoint inhibitor (nivolumab alone, pembrolizumab alone or nivolumab + ipilimumab) has been decided. 4. Subjects are included regardless of BRAFV600 mutation status. BRAFV600 mutation status must be documented. 5. Patient must be naïve to immune checkpoint inhibitor treatment for locally advanced and/or metastatic disease (i.e., no prior treatment with ICI and current treatment with ICI not yet started). 6. ECOG Performance status 0-2. 7. Life expectancy of at least 3 months. 8. Patient able to participate and willing to give informed consent prior to performance of any study-related procedures and to comply with the study protocol. 9. Patient affiliated to a Social Health Insurance in France. Exclusion Criteria: 1. Patient pregnant, or breast-feeding. 2. Uveal melanoma. 3. Any condition contraindicated with sampling procedures required by the protocol. 4. Any psychological, familial, geographic or social situation, according to the judgment of investigator, potentially preventing the provision of informed consent or compliance to study procedure. 5. Any current severe or uncontrolled disease, including, but not limited to ongoing or active infection. 6. Patient who has forfeited his/her freedom by administrative or legal award or who is under guardianship.
