Abstract
Objective: We describe patient-reported outcomes and quality of life through 5 years of treatment in patients with moderate-to-severe plaque psoriasis in the UNCOVER-1 and -2 studies.
Methods: This analysis included patients who were randomized to ixekizumab every 2 weeks then received ixekizumab every 4 weeks during the maintenance period, and who achieved static physician global assessment (0,1) at week 12, completed week 60, and entered the long-term extension period (weeks 60–264). Outcomes measures included responses in itch numeric rating scale (NRS), skin pain visual analog scale (VAS), and dermatology life quality index (DLQI) (0,1), and mean change from baseline in short form health survey (SF-36) mental (MCS) and physical component summaries (PCS), psoriasis skin appearance bothersomeness (PSAB), and work productivity activity impairment (WPAI).
Results: At week 264 in UNCOVER-1 and -2, the observed itch NRS ≥4 responses were 82.4% and 93.1%, respectively, the itch NRS=0 responses were 51.7% and 58.5%, respectively, the skin pain VAS=0 responses were 59.3% and 63.1%, respectively, and the DLQI (0,1) responses were 75.0% and 88.1%, respectively. The observed mean changes from baseline at week 264 in UNCOVER-1 and UNCOVER-2 were 3.4 and 6.5, respectively, for SF-36 MCS, 4.4 and 4.8, respectively, for SF-36 PCS, and -21.3 and -22.0, respectively, for PSAB. WPAI psoriasis item scores improved from baseline in both UNCOVER-1 and -2.
Conclusion: Ixekizumab provided clinically meaningful and sustained improvements in itch, skin pain, DLQI, PSAB, SF-36 PCS, SF-36 MCS, and WPAI through 5 years of treatment in patients with moderate-to-severe plaque psoriasis.

INTRODUCTION

Psoriasis is a chronic, systemic, immune-mediated disease recognized by its cutaneous manifestation of well-demarcated, erythematous, scaly plaques. These skin lesions, often associated with significant pruritus, stinging, and burning, cause substantial psychosocial impairment and overall decreased quality of life (QoL).1

Patient-reported outcome (PRO) measures provide patients and clinicians with a tool to assess physical and psychological functioning, facilitate treatment decision making, and identify coping strategies. When used effectively, individual and aggregated PRO data can inform and evaluate treatment, aid the holistic management of patients, and improve communication between patients and clinicians.2,3 The motivation to completely
