Simple Summary: Following surgery, dabrafenib and trametinib have been approved for the treatment of stage III melanoma with a B-RAF gene mutation. A retrospective–prospective observational trial conducted in Italy, known as MADAM (Maximizing ADjuvAnt MAP), included patients who had received at least one dose of trametinib plus dabrafenib. Following the first 24 months of follow-up, this analysis was the first. The trial involved 310 patients in total, of whom 240 completed the 12-month course of treatment, while 70 discontinued therapy. At 24 months, the majority of patients (80.2%) were alive and had not experienced disease relapse. The combination of trametinib and dabrafenib appears to benefit patients by lowering the rate of relapse. Background/Objective: Dabrafenib and trametinib (D + T) have been approved for the treatment of stage III melanoma with BRAF V600E V600K mutations in an adjuvant setting, based on the results from the COMBI-AD trial. To provide early access to this combination therapy prior to its commercial availability in Italy, a Managed Access Program (MAP) was run in Italy from June 2018 to December 2019. Methods: The MADAM (Maximing ADjuvAnt MAP) study is an Italian retrospective–prospective observational study that included patients who received at least one dose of D + T through the MAP. The primary endpoints were relapse-free survival (RFS) and overall survival (OS). Results: This interim analysis presents findings after the first 24 months of follow-up. A total of 310 patients were included in the study; 240 completed the 12-month treatment with D + T, while 70 discontinued the combination. RFS rates were 93.2% at 12 months and 80.2% at 24 months. The median RFS was not reached for the overall population or any subgroups. Similarly, the median OS was not reached, with OS rates of 96.4% at 12 months and 92.5% at 24 months. Conclusions: D + T achieved an RFS benefit, with effects sustained beyond the treatment period, indicating positive outcomes in this patient population. [ABSTRACT FROM AUTHOR]
