Is this trial a fit for you?

Likely a good fit

Adults (age ≥18) with metastatic melanoma in Slovenia who are planning to start first-line immunotherapy and can give informed consent are ideal candidates.

Probably not a fit

Patients who have already received prior systemic therapy for metastatic melanoma, cannot provide informed consent, or cannot attend the Ljubljana site or provide required samples are unlikely to qualify or receive benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, single-center study at the Institute of Oncology Ljubljana will enroll adults with metastatic melanoma who are starting first-line immunotherapy. Participants will undergo baseline and scheduled imaging (CT or PET/CT at baseline, week 4, week 12, and week 28) to measure response, and primary clinical outcomes include overall response rate, progression-free survival, and safety. Peripheral blood, stool, and available pleural or peritoneal effusion samples will be collected at predefined time points and analyzed for molecular tumor markers. Biomarker data will be correlated with imaging and clinical outcomes to identify prognostic and predictive markers that could support more personalized treatment decisions.

Why it matters

Potential benefit: If successful, the study could help identify which patients are likely to benefit from first-line immunotherapy and direct others to alternative treatments.

How similar studies have gone: Large trials of first-line immune checkpoint inhibitors have produced substantial survival benefits in metastatic melanoma, though robust predictive biomarkers for routine clinical use remain limited.
