Abstract
PURPOSE: To assess improvements in health-related quality of life (HRQoL) with ixekizumab treatment in patients with moderate-to-severe psoriasis.
METHODS: Adults with plaque psoriasis were enrolled in phase III, double-blind, randomised, controlled trials (UNCOVER-1, UNCOVER-2, or UNCOVER-3). All 3 protocols included a 12-week, placebo-controlled induction period; UNCOVER-2 and UNCOVER-3 also had an active-control group (50 mg etanercept) during induction. After induction, patients in UNCOVER-1 and UNCOVER-2 entered a 48-week withdrawal (maintenance) period (Weeks 12-60), during which Week-12 sPGA (0,1) responders were rerandomized to receive placebo, or 80 mg ixekizumab every 4 weeks (Q4W) or 12 weeks. As a secondary objective, HRQoL was measured by the generic Medical Outcomes Survey Short Form-36 (SF-36) at baseline and Weeks 12 and 60. Changes in mean SF-36 Physical and Mental Component Summary (PCS and MCS) and domain scores and proportions of patients reporting improvements ≥ minimal important differences in SF-36 scores were compared between groups.
RESULTS: At Week 12, ixekizumab-treated patients (both dose groups in UNCOVER-1, -2, and -3) reported statistically significantly greater improvements in mean SF-36 PCS and MCS and all 8 SF-36 domain scores versus placebo. Further, more ixekizumab-treated patients than placebo-treated patients reported at least minimal treatment responses in SF-36 PCS and MCS scores and domain scores. Overall improvements in SF-36 PCS and MCS scores were maintained through Week 60.
CONCLUSIONS: Ixekizumab-treated patients reported statistically significant improvements in HRQoL at 12 weeks that persisted through 1 year.
