Real-world nivolumab use in melanoma: what happens after surgery?
NCT ID NCT03771859
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watched 152 melanoma patients who had their tumors surgically removed and then started nivolumab as part of their normal care. Researchers tracked how long patients stayed cancer-free, whether the cancer spread, and overall survival. The goal was to see how well the drug works in everyday practice, not to test a new treatment.

Who is studied
Adults with melanoma with involvement of lymph nodes or metastatic disease who have undergone complete resection, and who receive adjuvant nivolumab under real-world conditions in Belgium or Luxembourg. Patients will be enrolled after complete surgical resection and following a screen procedure (according to standard practice) that shows no evidence of disease. Patients currently enrolled in an interventional clinical trial will not be eligible.

Inclusion Criteria: * Patients with a primary diagnosis of melanoma with involvement of lymph nodes or metastatic disease who have undergone complete resection and have no evidence of disease. * Decision to treat with adjuvant nivolumab therapy has already been taken * At least 18 years of age at the time of treatment decision * Patients who provide written informed consent to participate in the study (for retrospectively enrolled patients who are deceased at time of study start, a consent waiver will be sought) Exclusion Criteria: * Any patient with a diagnosis of persisting advanced melanoma prior to first administration of nivolumab * Any patient currently enrolled in an interventional clinical trial for his/her melanoma treatment (note: patients who have completed their participation in an interventional trial or who are no longer receiving the study drug and are only followed up for Overall Survival (OS)/ Relapse Free Survival (RFS) can be enrolled. In case of a blinded study, the treatment arm needs to be known). Other protocol defined inclusion/exclusion criteria could apply
