Summary Background Psoriasis has a negative impact on patients' quality of life. Treatment strategies should address both the cutaneous manifestations of the disease and their impact on quality of life. Objectives To evaluate the effect of alefacept on quality of life in 553 patients with chronic plaque psoriasis. Methods In this multicentre, double‐blind, parallel‐groups study, patients were randomized to receive alefacept for two courses, alefacept in course 1 and placebo in course 2, or placebo in course 1 and alefacept in course 2. In each course, alefacept 7·5 mg or placebo was administered once weekly by 30‐s intravenous injection for 12 weeks followed by 12 weeks of observation. The Dermatology Life Quality Index (DLQI), Dermatology Quality of Life Scales (DQOLS) and Short Form‐36 ™ Health Survey (SF‐36) were administered at baseline, 2 weeks after the last dose in both courses, at the beginning of course 2, and at the end of the observation period in both courses. Results In course 1, alefacept significantly reduced (improved) mean DLQI scores compared with placebo: 4·4 vs. 1·8 at 2 weeks after the last dose ( P < 0·0001) and 3·4 vs. 1·4 at 12 weeks after the last dose ( P < 0·001). Patients who received two courses of alefacept experienced additional enhancement of quality of life measures during the second course. Similar results were observed for the DQOLS. The SF‐36 survey confirmed that alefacept had no negative impact on general quality of life. Conclusions Alefacept improved quality of life in patients with chronic plaque psoriasis and maintained this benefit for at least 12 weeks following cessation of treatment. A second course of alefacept provided additional quality of life benefit.
