Multicenter Study
Survival rates of biological therapies for psoriasis treatment in real-world clinical practice: A Canadian multicentre retrospective study.
Australasian Journal of Dermatology 2018 Februrary
BACKGROUND/OBJECTIVES: Data on biologic drug survival in real-world psoriasis treatment are limited. There is a need to evaluate long-term trends of biologic use outside the realm of clinical trials.
METHODS: A multicentre chart review was conducted with patients' data from September 2005 to September 2014. Kaplan-Meier plot analysis was used to determine 5-year drug survival rates. A log-rank test was used to compare the rates of drug survival between the studied biologics.
RESULTS: For the 398 patients and 545 treatment series analysed, 1, 2, 3, 4 and 5-year survival rates were 0.826, 0.687, 0.563, 0.475 and 0.420 with etanercept; 0.804, 0.648, 0.553, 0.508 and 0.508 with adalimumab; 0.838, 0.664, 0.554, 0.485 and 0.382 with infliximab; and 0.914, 0.856, 0.800, 0.755 and 0.755 with ustekinumab, respectively. A statistically significant difference was seen between ustekinumab and the other three biologics.
CONCLUSION: A progressive decrease in treatment adherence was seen with all four biologics, as expected, but the survival rate of ustekinumab was highest.
