This study evaluated the long term trends of biologic use outside the realm of clinical trials. The following Bio's were used.
Enbrel (etanercept)
Humira (adalimumab)
Remicade (infliximab)
Stelara (ustekinumab)

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.
