Abstract:
Continuous treatment is recommended for patients with moderate‐to‐severe psoriasis; however, treatment may need to be interrupted in routine clinical practice. Objective To assess outcomes in patients continuously treated with ixekizumab versus those who interrupted therapy and were subsequently retreated with ixekizumab ( IXE ). Methods This analysis used data pooled from two phase 3 trials, UNCOVER ‐1 and UNCOVER ‐2. Patients were randomized to placebo ( PBO ), IXE every 4 (Q4W) or IXE every 2 weeks (Q2W) for 12 weeks. Patients with a static Physician's Global Assessment ( sPGA ) 0, 1 at Week 12 were rerandomized to IXEQ 4W, IXE every 12 weeks (not presented) or PBO . We examined outcomes in patients who were continuously treated ( IXEQ 2W/ IXEQ 4W; IXEQ 4W/IXEQ4W) or withdrawn ( IXEQ 2W/ PBO ; IXEQ 4W/ PBO ), and in patients who were withdrawn and retreated with IXEQ 4W for 24 weeks after disease relapse ( sPGA ≥3). Results A total of 1226 treated patients achieved an sPGA 0, 1 at Week 12 and entered the maintenance phase; of these patients, 402 and 416 were rerandomized to PBO and IXEQ 4W, respectively. Among patients interrupting treatment, 157 (82.2%) of IXEQ 4W/ PBO and 176 (83.4%) of IXEQ 2W/ PBO had an sPGA ≥3 by Week 60; median time to relapse was approximately 20 weeks irrespective of induction dose. At Week 60, continuously treated patients maintained high levels of PASI and sPGA responses (90.0% PASI 75 IXEQ 2W/IXEQ4W; 81.9% sPGA 0, 1 IXEQ 2W/IXEQ4W, non‐responder imputation). After 24 weeks of retreatment with IXEQ 4W ( IXEQ 2W/ PBO /IXEQ4W and IXEQ 4W/ PBO /IXEQ4W), 87.0% (107 of 123) and 95.1% (97 of 102) (observed), respectively, of patients recaptured PASI 75 and 70.7% (104 of 147) and 82.3% (107 of 130) (observed) recaptured an sPGA 0, 1. Overall, adverse events in continuously treated and retreated patients were comparable. Conclusion High levels of response were sustained with continuous ixekizumab treatment through 60 weeks. Most patients who were withdrawn experienced disease relapse, and most of those patients recaptured response after 24 weeks of retreatment.
