Biomarker hunt: could IFN-Gamma guide melanoma treatment?
NCT ID NCT07436390
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 132 people with advanced melanoma to see if levels of a protein called interferon-gamma (IFN-γ) in their tumors or blood could predict how well they would respond to first-line immunotherapy drugs like pembrolizumab, nivolumab, or a combination. The goal is to find a reliable biomarker to personalize treatment and avoid giving ineffective therapies. The study also explored whether gut bacteria play a role in treatment outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pembrolizumab, Nivolumab, Ipilimumab/Nivolumab
- What this could lead to
- If successful, this could help doctors choose the right immunotherapy for each patient, improving response rates and reducing unnecessary side effects.
- What could go wrong
- This is an observational study, not a treatment trial. The biomarker may not reliably predict response, and results may not change clinical practice immediately.

Inclusion Criteria: * Age over 18 years * Cytologically or histologically verified malignant melanoma * Stage IIID unresectable/IV according to AJCC classification (8th edition, 2018) * Performance status WHO 0-2 (ECOG criteria) * First-line systemic immunotherapy treatment (nivolumab, ipilimumab/nivolumab combination, pembrolizumab) * CT triple scan/PET CT performed within 4 weeks prior to the first administration * Signed informed consent for participation in the clinical study Exclusion Criteria: * Previous systemic therapy for melanoma * Performance status WHO 3-4 (ECOG criteria) * Contraindications for immunotherapy (known immune deficiency, active immunosuppressive treatment, or active autoimmune disease requiring treatment) * Other malignant diseases (except cured basal cell carcinoma, squamous cell carcinoma, and other cured solid tumors without recurrence more than three years after treatment)
