Summary

Itching is a prevalent plaque psoriasis symptom. Ixekizumab, an IL-17A antagonist, has demonstrated rapid, significant improvements in itch severity over 12 weeks in Phase III psoriasis trials (UNCOVER-1, UNCOVER-2). We assessed the long-term (through 60 weeks) effect of ixekizumab maintenance therapy (80-mg ixekizumab every 4 weeks [IXEQ4W]) on itch severity, using the Itch Numeric Rating Scale, in psoriasis patients who received ixekizumab, placebo, or etanercept for 12 weeks in the Phase III UNCOVER-3 trial. After 12 weeks, patients either continued or switched to IXEQ4W. Mean improvements in itch severity achieved with 12 weeks of ixekizumab (-4.7 to -5.1) were maintained through 60 weeks with IXEQ4W (-4.9 to -5.0). Patients who initially received placebo or etanercept experienced rapid itch severity improvements after switching to ixekizumab at Week 12 (Week 12, placebo: -0.6; etanercept: -3.8; Week 60, placebo/IXEQ4W: -4.9; etanercept/IXEQ4W: -4.7). Ixekizumab maintenance therapy sustained improvements in itch severity through 60 weeks.
