Brief Summary:
This is a 3-period study comparing CHS-1420 to Humira in patients with chronic plaque psoriasis.

Condition or disease Intervention/treatment Phase
Plaque Psoriasis Drug: CHS-1420 Drug: Adalimumab Phase 3

Detailed Description:

This is a 55-week, randomized, double-blind, active-control, parallel group, multicenter, global study in subjects with active, moderate to severe, chronic PsO.

The study will consist of 24 weeks of administration of blinded study drug, divided into Treatment Period 1 and Treatment Period 2, then 23 weeks of administration of open-label CHS-1420 and a Follow-up visit 8 weeks after the last dose. Subjects who meet inclusion/exclusion criteria will be stratified by body mass index (BMI), and age and randomized 1:1 to receive CHS-1420 or Humira in Treatment Period 1. Subjects assigned to CHS-1420 will continue to receive CHS-1420 in Period 2. Subjects assigned to Humira in Period 1 will be randomly assigned (1:1) to either continue with Humira in Treatment Period 2 or to switch to CHS-1420 in Treatment Period 2. All subjects will receive open label CHS-1420 in Treatment Period 3.

Drug Information available for: Adalimumab

Arm Intervention/treatment
Active Comparator: Humira (adalimumab)
Adalimumab (Humira) 40mg 2 doses at week 0/Day 0, then 1 dose every 2 weeks starting at Week 1 until Week 15. At Week 16 subjects initially randomized to adalimumab will be assigned (1:1) to CHS-1420 or continue adalimumab treatment, 1 dose every 2 weeks for weeks 17-23. The assignments for treatment sequences (Treatment Period 1 and Treatment Period 2) were made randomly at the beginning of Treatment Period 1. At week 24 subjects will switch to CHS-1420 open label until study end.
Drug: CHS-1420
Drug: Adalimumab
Other Name: Humira

Experimental: CHS-1420
CHS-1420 40mg 2 doses at Week 0/Day 0 then 1 dose every 2 weeks starting at Week 1 for 23 weeks. At Week 24 subjects will continue on to CHS-1420 open label until study end.
Drug: CHS-1420

Primary Outcome Measures :
  1. Difference Between the Percentage of Subjects in Each Treatment Group Achieving a 75% Improvement in Psoriasis Area and Severity Index (PASI-75) at Week 12 [ Time Frame: 12 weeks ]
    The efficacy success criterion was the equivalence between CHS-1420 and Humira at Week 12. Equivalence was based upon 2-sided 95% confidence interval (CI) for the difference between the proportions of subjects in the CHS-1420 and Humira groups achieving PASI-75 at Week 12. If the 95% CI lay entirely within the interval (-15%, 15%), equivalence was established.
