What was measured
Relapse-Free Survival (RFS) was defined as the time from randomization to disease recurrence or death from any cause. RFS events included loco-regional recurrence, distant metastases, new primary melanoma, and death without prior documented recurrence; such deaths were counted as events and not censored. Patients without an event at the analysis cut-off (30-Jun-2017) were censored at the date of the last radiological or non-radiological efficacy assessment. Patients lost to follow-up before recurrence or who initiated subsequent anti-cancer therapy prior to recurrence were censored at the last efficacy assessment before loss to follow-up or therapy initiation. Events after prolonged loss to follow-up were handled per the analysis plan. Malignancies other than new primary melanoma were not considered RFS events and, except for basal cell carcinoma, were reported as serious adverse events. Tumor tissue from any new primary cancer was collected for biomarker analyses.
