and Treatment-Emergent Adverse Events of Iritis in Ixekizumab
adverse events are defined as events that first occurred or worsened
in severity, relative to baseline, at any time during a clinical
study. The stated frequencies of adverse reactions represent the
proportion of individuals who experienced, at least once, a TEAE of
the type listed. Adverse events reported during the studies were not
necessarily caused by the therapy and the frequencies do not reflect
investigator assessment of causality.

recommendation. Decisions regarding the use of ixekizumab in patients
with iritis (or any medical condition) should be made at the
discretion of the prescribing physician using their best clinical

Brief Clinical Trial Descriptions
-2, and -3 (N=3866) phase 3 trials in moderate-to-severe plaque
psoriasis were integrated to evaluate the safety of ixekizumab in
comparison to placebo up to 12 weeks after treatment initiation.
phase 3 trials examined the efficacy and safety of ixekizumab
compared with placebo and etanercept (UNCOVER-2 and -3) during
induction treatment and vs placebo in maintenance (UNCOVER-1 and
