Patients
To be eligible, patients had to be between 18 and 80 years of age and have plaque psoriasis at screening that was severe enough for a systemic therapy. Patients with poorly controlled medical conditions such as uncontrolled diabetes; patients with symptoms of demyelinating diseases, a history of cancer, listeriosis, tuberculosis, persistent chronic infections, or immunodeficiency; or patients who had taken live attenuated vaccine within 28 days of baseline were excluded from the study.

Demographics and patient disposition
A total of 85 patients were included in this study (50 patients in group A and 35 patients in group B). The original plan was to include 50 patients in both groups. However, recruitment of patients who presented a PGA score of 0 or 1 after 12 weeks of etanercept followed by an increase in PGA score to 2 or higher upon etanercept dose reduction was more difficult than anticipated. As recruitment was not progressing, it was decided to stop enrollment during the spring of 2008. Demographics of
Discussion
Treatment of patients with moderate to severe psoriasis has changed dramatically since the approval of biological agents. In addition to topical therapy, phototherapy, and the oral systemic agents, there are, at the time of this writing, 5 biologics approved in various countries for the treatment of psoriasis with at least one more pending approval.7, 8 Choosing the best treatment for moderate to severe psoriasis becomes more complex both for patients and clinicians.
