Brief Summary:
The purpose of the study is to evaluate pharmacokinetic equivalence, efficacy, safety and immunogenicity of multiple switches between ustekinumab and ABP 654 compared with continued use of ustekinumab in participants with moderate to severe plaque psoriasis.

Condition or disease Intervention/treatment Phase
Psoriasis Drug: Ustekinumab Drug: ABP 654 Phase 3

Detailed Description:

This is a multi-center study and will enroll approximately 352 participants.

After eligibility confirmation, all participants will be randomized in a 1:1 ratio into 2 treatment arms: continued use of ustekinumab or multiple switches between ustekinumab and ABP 654 at Week 28. The randomization will be stratified by prior biologic use for psoriasis (yes versus [vs] no) at baseline (Week 0), geographic region, and baseline (Week 0) body weight.

All participants will receive an initial 3 doses of ustekinumab on Day 1 (Week 0), Week 4 and Week 16. At Week 28, participants will be randomized to continue on ustekinumab or switching between ABP 654 and ustekinumab every 12 weeks.

At Week 28, efficacy assessments will be conducted including evaluation of Psoriasis and Area Severity Index (PASI). Participants who do not achieve PASI 50 response or better improvement at Week 28 will be considered as run-in failures and will not be randomized at Week 28; these participants will complete End of Study procedures at Week 28. The run-in period will occur from Day 1 until randomization at Week 28. Those unable to complete the Week 28 visit or did not have a PASI assessment completed at Week 28 will be discontinued from the study.

The total duration of study participation for each participant will be 68 weeks, with up to 4 weeks for screening and 64 weeks after the first investigational product administration.

Primary Outcome Measures :
  1. Area Under the Curve from Time 0 over the Dosing Interval (AUCtau) [ Time Frame: Week 52 (pre-dose and post-dose) until Week 64 ]
    To evaluate AUCtau in participants with multiple switches between ustekinumab and ABP 654 compared to participants receiving continued use of ustekinumab.

  2. Maximum Concentration (Cmax) [ Time Frame: Week 52 (pre-dose and post-dose) until Week 64 ]
    To evaluate Cmax in participants with multiple switches between ustekinumab and ABP 654 compared to participants receiving continued use of ustekinumab.


Secondary Outcome Measures :
  1. Time of Maximum Concentration (tmax) [ Time Frame: Week 52 (pre-dose and post-dose) until Week 64 ]
    To assess the tmax in participants with multiple switches between ABP 654 and ustekinumab compared with participants receiving continued use of ustekinumab.

  2. Trough Concentration at Steady State (Ctrough,ss) [ Time Frame: Week 28 (pre-dose and post-dose) until Week 52 (pre-dose and post-dose) ]
    To assess the Ctrough,ss in participants with multiple switches between ABP 654 and ustekinumab compared with participants receiving continued use of ustekinumab.

  3. Percent Improvement in PASI From Baseline to Week 64 [ Time Frame: Baseline (Day 1) until Week 64 ]
    The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling); each graded on a 0-4 scale (0 = clear; 1-4= increasing severity) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity.

  4. Percentage of Participants with PASI 75 Response at Week 64 [ Time Frame: Week 64 ]
    Reduction in disease as measured by PASI score. The PASI 75 response is a 75% or greater improvement (reduction in disease [PASI 75]) from baseline in PASI score. The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling; each graded on a 0-4 scale (0 = clear; 1-4= increasing severity) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity.

  5. Percentage of Participants with PASI 100 Response at Week 64 [ Time Frame: Week 64 ]
    Reduction in disease as measured by PASI score. The PASI 100 response is a 100% improvement (reduction in disease [PASI 100]) from baseline in PASI score. The PASI is a measure of the average redness (erythema), thickness (induration), and scaliness (scaling; each graded on a 0-4 scale (0 = clear; 1-4= increasing severity) of the lesions, weighted by the area of involvement in the four main body areas (i.e., head, arms, trunk to groin, and legs to top of buttocks). The PASI score ranges from 0 to 72. The higher score represents the worse symptom severity.

  6. Number of Participants With Treatment Emergent Adverse Events and Serious Adverse Events [ Time Frame: Week 28 until Week 64 ]
    To assess the safety in participants with multiple switches between ABP 654 and ustekinumab compared with participants receiving continued use of ustekinumab.

  7. Number of Participants With Events of Interest [ Time Frame: Week 28 until Week 64 ]
    To assess the safety in participants with multiple switches between ABP 654 and ustekinumab compared with participants receiving continued use of ustekinumab.

  8. Number of Participants With Positive Anti-drug Antibodies to ABP 654 [ Time Frame: Week 28 until Week 64 (Pre-dose) ]
    To assess the immunogenicity in participants with multiple switches between ABP 654 and ustekinumab compared with participants receiving continued use of ustekinumab.
