WPAI-PSO Questionnaire: Impairment of work productivity and engagement in activities outside work was assessed as a pre-specified secondary endpoint in UNCOVER-1, -2, and -3 clinical trials of patients with moderate to severe psoriasis using a validated, self-reported instrument. The WPAI-PSO questionnaire was used to determine the impact of psoriasis on work productivity in patients who received ixekizumab. The 4 scores derived from the WPAI-PSO are
absenteeism (% work time missed),
presenteeism (% impairment at work),
WPL (% overall work impairment associated with absenteeism and presenteeism), and
UNCOVER-1 Through Week 12: The results of the questionnaire demonstrated a significant improvement from baseline to week 12 compared to placebo in WPAI-PSO scores of
absenteeism (Q2W, p=.003; Q4W, p<.001),
presenteeism (p<.001 for both doses),
WPL (p<.001 for both doses), and
activity impairment (p<.001 for both doses).1
UNCOVER-2 and -3 Through Week 12: UNCOVER-2 and UNCOVER-3 week 12 results were similar to the results from UNCOVER-1. With Q2W dosing in both trials, ixekizumab results for each of the 4 WPAI-PSO scores were significant compared to placebo (p<.001 for all scores vs placebo except for absenteeism [p=.02 and p=.01 in UNCOVER-2 and -3, respectively]).2
UNCOVER-1 Through Week 60: As illustrated in Figure 1 below, week 12 responder patients (defined as sPGA 0 or 1) who were re-randomized to treatment with ixekizumab Q4W for the 48-week maintenance period demonstrated a sustained reduction in
activity impairment (p<.001 for each at Week 60 compared to those who had been re-randomized to placebo).
Significant improvement for absenteeism compared to placebo in week 12 responders who were re-randomized to ixekizumab Q4W was only achieved at week 52.1

*p<.05, **p ≤.01, *** p≤.001 – vs IXE/PBO.
UNCOVER-2 Through Week 60: In UNCOVER-2, week 60 results were similar to those from UNCOVER-1. Week 12 responders who were re-randomized to ixekizumab Q4W for the maintenance period demonstrated a sustained reduction in
activity impairment ( p<.001 for each at week 60 compared to responders re-randomized to placebo ).
A post hoc analysis evaluated the relationship between WPAI-PSO and PASI improvements. Greater WPAI score improvements were seen in those with greater PASI score improvement (Data not shown).2
