median drug survival time when excluding non-biologic-naïve patients. They additionally found a 4-year drug survival rate of 40% in biologic-naïve patients, similar to our rate as illustrated by Figure 2. In comparison to a large-scale, recently published study with a 1-year survival rate of 70%, our 1-year drug survival rate was around 80%.5
Although this study is limited by 5% of patients lost to follow up, it provides response durations in a substantial cohort size that can guide expectations of patients starting biologic therapy for the first time. Our results demonstrate that the efficacy of etanercept therapy diminishes with time (Figure 2). Additionally, the biologic-naïve status of our cohort yielded data unaffected by other biologic agents, important given that studies have shown diminished efficacy in patients that switch between agents.4 Although new agents continue to be developed, dermatologists frequently prescribe etanercept therapy, and future studies should investigate methods to optimize this treatment modality and minimize treatment dissatisfaction amongst patients.
