Abstract

BACKGROUND: Ixekizumab is an interleukin-17A antagonist approved for treatment of moderate-to-severe plaque psoriasis with a recommended 160-mg starting dose, then 80 mg every 2 weeks (Q2W) to week 12, and every 4 weeks (Q4W) thereafter. OBJECTIVE: To evaluate continuous Q2W dosing over 52 weeks. METHODS: In this phase III, multicentre, double-blinded, parallel-group trial, three ixekizumab dosing regimens were assessed for efficacy and safety at week 52 in patients with moderate-to-severe plaque psoriasis randomized at a 2 : 1 : 1 ratio to continuous Q2W (n = 611), continuous Q4W (n = 310) or dose adjustment per protocol (Q4W/Q2W, n = 306), each with a 160-mg starting dose. Dose adjustment ..
