ReportClinical response to adalimumab treatment in patients with moderate to severe psoriasis: Double-blind, randomized controlled trial and open-label extension study
Section snippets
Patients
Eligible patients included men and women age 18 years and older with plaque psoriasis of at least 1-year duration and involving 5% or more of their body surface area. Patients had active psoriasis despite topical therapies and were all naive to anti-TNF treatment. Concomitant psoriasis therapies were not allowed with the exception of low- to mid-potency corticosteroids applied topically to the palms, soles, face, and groin. The washout period for prior psoriasis therapies was 2 weeks for
Patients
A total of 148 patients were randomized and 147 patients received at least one dose of study medication and were included in the efficacy analyses; one patient was randomized to the eow group, but did not receive study drug because of withdrawal of informed consent (Fig 2). The first study patient was screened in March 2003, and the last patient's final study visit was in June 2004. The majority of patients (95% [140 of 147]) completed the initial 12-week study with no differences observed in
Discussion
In this multicenter, randomized, placebo-controlled trial, adalimumab demonstrated both short- and long-term, statistically and clinically significant efficacy in the treatment of psoriasis as assessed by a variety of efficacy measures. At week 12 of the study, 53% of patients who had received 40 mg of adalimumab eow and 80% of patients who had received 40 mg/wk of adalimumab achieved at least PASI 75 compared with 4% of patients who had received placebo (P < .001). The patients treated with
