Here we aimed to describe the characteristics, dosage reductions and discontinuations in patients with BRAFV600E/K-mutated melanoma receiving adjuvant dabrafenib plus trametinib after surgical resection through an Italian managed access program (MAP).Patients and Methods: Eligible patients had completely resected cutaneous melanoma with confirmed BRAF V600E or V600K mutation, or initially resectable lymph node recurrence after a diagnosis of stage I or II melanoma. The starting dose of dabrafenib and trametinib was 150 mg twice daily and 2 mg once daily, respectively.Results: A total of 557 patients received dabrafenib plus trametinib through the MAP (stage III resected disease at inclusion, 554). Median age was 54.0 years, and 40.2% of patients were female. The proportion of all treated patients who required a dose reduction was low (10.8%) as was the proportion of patients who discontinued treatment (13.5%). The main reason for treatment discontinuation was adverse events (36.0%).Conclusion: New treatments, including BRAF-targeted therapies and immunotherapy, have transformed the natural history of melanoma. This is the largest study to date describing patients treated with dabrafenib plus trametinib in routine clinical practice in Italy between 2018 and 2019. Results highlight the characteristics of the patients treated and their journey, as well as the tolerable safety profile of dabrafenib plus trametinib in a real-world patient population.Keywords: BRAF mutation, dabrafenib, melanoma, real-world, trametinib, managed access program
