Efficacy and safety of adalimumab in patients with plaque psoriasis who have shown an unsatisfactory response to etanercept - 24/04/13
Abstract |
Background |
The safety and efficacy of adalimumab in patients who have shown an unsatisfactory response to etanercept are unknown.
Objective |
We sought to evaluate the safety and efficacy of adalimumab in patients who failed to show a satisfactory response or lost their satisfactory response to etanercept.
Methods |
This multicenter study enrolled patients who either failed to reach a physician global assessment (PGA) score of 0 or 1 after 12 weeks of etanercept (group A; 50 patients) or who lost their PGA score of 0 or 1 at any time after etanercept dose decrease from 50 mg twice a week to 50 mg every week (group B; 35 patients). Patients received adalimumab 40 mg every other week without loading dose for 12 weeks followed by 40 mg every week for an additional 12 weeks if they did not reach a PGA score of 0 or 1.
Results |
After 12 weeks of adalimumab, 34.0% (n = 17; 95% confidence interval [CI] 20.4-47.6) and 31.4% (n = 11; 95% CI 15.2-47.6) of patients from groups A and B, respectively, reached a PGA score of 0 or 1. A total of 46.0% (n = 23; 95% CI 31.7-60.3) and 45.7% (n = 16; 95% CI 28.4-63.1) of patients from group A and B, respectively, achieved a PGA score of 0 or 1 after 24 weeks of adalimumab. Adalimumab was well tolerated and no serious adverse events were reported.
Limitations |
This was an open-label uncontrolled study.
Conclusions |
Adalimumab should be considered as an alternative in patients with psoriasis who have not shown an adequate response or who lost their response to etanercept after a dose decrease.
