title: Efficacy and safety of guselkumab, an anti-interleukin-23 monoclonal antibody, compared with adalimumab for the treatment of patients with moderate to severe psoriasis with randomized withdrawal and retreatment: Results from the phase III, double-blind, placebo- and active comparator-controlled VOYAGE 2 trial.
abstract: BACKGROUND
  Phase II data suggested that guselkumab, an anti-interleukin-23 monoclonal antibody, was efficacious in psoriasis.
  
  
  OBJECTIVE
  We sought to assess efficacy and safety of guselkumab in moderate to severe psoriasis versus placebo and adalimumab, including interrupted treatment and switching adalimumab nonresponders to guselkumab.
  
  
  METHODS
  Patients were randomized to guselkumab 100 mg (weeks 0 and 4, then every 8 weeks; n = 496); placebo→guselkumab (weeks 0, 4, and 12 then guselkumab at weeks 16 and 20; n = 248); or adalimumab (80 mg week 0, then 40 mg week 1, and every 2 weeks through week 23; n = 248). At week 28, guselkumab 90% or greater improvement in Psoriasis Area and Severity Index (PASI) score from baseline (PASI 90) responders were rerandomized to guselkumab or placebo with guselkumab after loss of response. Placebo→guselkumab responders and adalimumab responders received placebo, then guselkumab after loss of response. Nonresponders received guselkumab.
  
  
  RESULTS
  At week 16, more patients receiving guselkumab achieved an Investigator Global Assessment (IGA) score 0/1 (cleared/minimal) (84.1% vs 8.5%) and PASI 90 (70.0% vs 2.4%) versus placebo (coprimary end points). Guselkumab was superior to adalimumab at week 16 (IGA score 0/1, 75% or greater improvement in PASI score from baseline, and PASI 90) and week 24 (IGA score 0/1 and 0, PASI 90, 100% improvement in PASI score from baseline) (P < .001). From weeks 28 to 48, better persistence of response was observed in guselkumab maintenance versus withdrawal groups (P < .001). Of adalimumab nonresponders who switched to guselkumab, 66.1% achieved PASI 90 at week 48. Guselkumab improved patient-reported outcomes. Adverse events were comparable among groups.
  
  
  CONCLUSIONS
  One-year follow-up limits retreatment data.
  
  
  CONCLUSIONS
  Guselkumab is a highly effective, well-tolerated, maintenance therapy, including in adalimumab nonresponders.
