摘要
REVEAL was a 52-week phase III trial of adalimumab therapy for moderate to severe chronic plaque psoriasis. Patients from REVEAL could enter an open-label extension trial to receive adalimumab for approximately 3 years of total therapy.We sought to determine long-term efficacy and safety of continuous adalimumab therapy for patients from REVEAL.Efficacy and safety over greater than 3 years of treatment were analyzed for 4 groups of patients from REVEAL. Patients who received adalimumab continuously from baseline were grouped by their responses in REVEAL: (1) greater than or equal to 75% improvement in Psoriasis Area and Severity Index (PASI) score (PASI 75) at weeks 16 and 33 (sustained responders); (2) less than PASI 75 at week 16; and (3) greater than or equal to PASI 75 at week 16 with 50% to less than 75% improvement in PASI score at week 33. Results were also analyzed for patients who began adalimumab after 16 weeks of placebo therapy.For patients with sustained PASI 75 responses during REVEAL, efficacy was generally well maintained over 3 years, with 75%/90%/100% improvement in PASI score response rates (last observation carried forward) of 83%/59%/33% after 100 weeks and 76%/50%/31% after 160 weeks of continuous therapy. Some patients with less than PASI 75 responses in REVEAL also achieved long-term PASI 75 responses. Efficacy in the placebo/adalimumab group was consistent with the ensemble of results from the other 3 groups. Adverse event rates were consistent with those during REVEAL.The REVEAL study design prevented analyzing all patients from the adalimumab arm as one long-term cohort.Adalimumab efficacy was well maintained over more than 3 years of continuous therapy for patients with sustained initial PASI 75 responses. Maintenance was best at the PASI 100 level.
