Given the approval of dabrafenib in patients with BRAF-mutant metastatic melanoma, a better understanding of treatment patterns and clinical outcomes with dabrafenib in a clinical setting is warranted. We performed a retrospective chart review of patients who received dabrafenib in a compassionate use setting through the Named Patient Program (DESCRIBE I study) during December 2010-August 2013 in Europe, New Zealand and Australia. Of the 331 Named Patient Program patients included, the majority (95.8%) had stage IV disease at dabrafenib initiation and 39.9% had brain metastases (BMs). Dabrafenib was used first line in 67.7% of patients, and median treatment duration was 6.4 months. Dabrafenib was well tolerated. Common grade 2/3 adverse events were hyperkeratosis (7.6%), pyrexia/fever (6.6%), fatigue (5.1%), hand-foot syndrome (5.4%) and nausea (3.6%). Overall response rate was 45.9%, median progression-free survival was 5.2 months (95% confidence interval, 4.2-6.1 months), and median overall survival was 12.4 months (95% confidence interval, 10.2-15.0 months). In patients with known brain metastases (n = 132) versus patients without (n = 199), overall response rate was 42.4% versus 48.2%, progression-free survival was 3.9 months (95% confidence interval, 3.8-5.5 months) versus 5.9 months (95% confidence interval, 4.8-7.8 months) and overall survival was 9.5 months (95% confidence interval, 6.7-12.4 months) versus 15 months (95% confidence interval, 11.1-20.5 months), respectively. Safety and effectiveness of dabrafenib in patients with unresectable advanced BRAF V600-mutant melanoma treated in an Named Patient Program was similar to the clinical trial experience, demonstrating effectiveness of dabrafenib in a nontrial setting.
