BACKGROUND: Information is limited on the use of vismodegib for treatment of advanced basal cell carcinoma beyond the setting of clinical trials. OBJECTIVE: To investigate the treatment patterns and characteristics of patients treated with vismodegib in clinical practice. METHODS: A longitudinal, retrospective cohort study was undertaken using data from a US commercial insurance claims (Truven Health Analytics MarketScan) database. Eligible patients were ≥18 years of age, with ≥1 claim for vismodegib from January 2012 to December 2015. RESULTS: A total of 321 patients were included in the analysis. Approximately 20% of the patients took 1 or more treatment breaks of ≥ 30 days each before treatment discontinuation. Median duration of vismodegib treatment before the first treatment break and discontinuation was 4.0 and 5.5 months, respectively. Older age ( > 65 years) and absence of Gorlin syndrome were associated with increased risk for treatment interruption or discontinuation. Overall, 47% and 36% of patients underwent surgery or radiotherapy within the 6 months before and after vismodegib initiation, respectively. CONCLUSIONS: Real-world evidence indicates that vismodegib is being used in clinical practice as part of combination treatment strategies. J Drugs Dermatol. 2018;17(2):143-148.
