Efficacy and Safety of Ixekizumab Through 5 Years in Moderate-to-Severe Psoriasis: Long-Term Results from the UNCOVER-1 and UNCOVER-2 Phase-3 Randomized Controlled Trials.

INTRODUCTION: Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for treatment of moderate-to-severe plaque psoriasis. Our objective was to evaluate the long-term efficacy and safety of ixekizumab in moderate-to-severe plaque psoriasis through 5 years. METHODS: Data were integrated from the UNCOVER-1 and UNCOVER-2, randomized, double-blinded, phase-3 trials. Patients who continuously received the labeled ixekizumab dose, were static Physician's Global Assessment (sPGA) (0,1) responders at Week 12 and completed 60 weeks of treatment could enter the long-term extension (LTE) period. Patients could escalate to every-2-week dosing per investigator opinion. Efficacy and health outcomes included proportion of patients achieving Psoriasis Area and Severity Index (PASI) 75/90/100, sPGA (0,1) and (0), absolute PASI
