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

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

Detailed Description:

This is a multicenter study and will enroll approximately 542 participants.

The total duration of study participation for each participant will be 56 weeks, with up to 4 weeks for screening, and for 52 weeks after the first administration of either ABP 654 or ustekinumab.

After confirmation of eligibility, all participants will be randomized in a 1:1 ratio into 2 treatment groups (Group A will receive ABP 654, and Group B will receive ustekinumab) stratified by prior biologic use for psoriasis (yes versus [vs] no), geographic region, and baseline body weight (BW).

Based on the psoriasis area and severity index (PASI) score (to determine better improvement or partial improvement) at week 28, the participants in the study will proceed as follows:

  1. Participants who do not achieve PASI 50 response or better improvement at Week 28 will be considered to have completed the study and will complete end of study procedures (ie, week 52 procedures), and those unable to complete week 28 visit, or did not have a PASI assessment completed, will be discontinued from the study.
  2. Participants who achieve PASI 75 response or better improvement will continue on the study and will be re-randomized in a blinded fashion such that participants initially randomized to Group A (ABP 654) will continue to receive ABP 654 and those in Group B (ustekinumab) will re-randomized, to either continue on ustekinumab (Treatment Group B1) or switch to ABP 654 (Treatment Group B2).
  3. Participants with PASI 50 response or better but less than PASI 75 response and on the Investigator's decision, participants will continue on the originally assigned treatment with dose intensification and will not be re-randomized. However, participants that do not dose intensify will be re-randomized.

Arm Intervention/treatment
Experimental: Treatment Group A (ABP 654)
Participants will receive subcutaneous (SC) injection of ABP 654, 45 mg (baseline BW less than equal to [<=] 100 kg) or 90 mg (baseline BW greater than [>] 100 kg) at weeks 0, 4, and 16. Further from week 28 participants will receive ABP 654 (same dose) every 12 weeks (Q12W) at weeks 28 and 40 or may receive dose intensification Q8W at weeks 28, 36, and 44, depending on PASI score.
Drug: ABP 654
Participants will receive SC injection of ABP 654.

Experimental: Treatment Group B (Ustekinumab - ABP 654)
Participants will receive SC injection of ustekinumab,45 mg (baseline BW <= 100 kg) or 90 mg (baseline BW > 100 kg) at weeks 0, 4, and 16. At week 28, participants will be re-randomized to continue on ustekinumab (Treatment group B1), or to receive ABP 654 (Treatment group B2) on weeks 28 and 40. Depending on PASI score, some participants may not be re-randomized and may receive dose intensification with ustekinumab Q8W at weeks 28, 36, and 44.
Drug: ABP 654
Participants will receive SC injection of ABP 654.

Drug: Ustekinumab
Participants will receive SC injection of ustekinumab.
Other Name: Stelara®




Primary Outcome Measures :
  1. Percent Improvement in PASI From Baseline to Week 12 [ Time Frame: Baseline (Day 1 [Week 0]) until Week 12 ]
    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.


Secondary Outcome Measures :
  1. Percent Improvement in PASI at Other Timepoints [ Time Frame: Baseline (Day 1 [Week 0]), weeks 4, 12, 16, 28, 36, 40, 44 and Week 52 (end of study [EOS]) ]
    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.

  2. Percentage of Participants with PASI 75 Response Throughout the Study [ Time Frame: Baseline (Day 1 [Week 0]), weeks 4, 12, 16, 28, 36, 40, 44 and Week 52 (EOS) ]
    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.

  3. Percentage of Participants with PASI 100 Response Throughout the Study [ Time Frame: Baseline (Day 1 [Week 0]), weeks 4, 12, 16, 28, 36, 40, 44 and Week 52 (EOS) ]
    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.

  4. Percentage of Participants With Static Physician's Global Assessment (sPGA) Responses (0/1) at Week 12 and Week 52 [ Time Frame: Week 12 and Week 52 ]
    The sPGA is a 6-point scale ranging from 0 (clear) to 5 (very severe) used to measure the severity of disease (induration, scaling, and erythema). A sPGA response is defined as a sPGA value of clear (score 0) or almost clear (score 1). The higher score represents the worse symptom severity.

  5. Change From Baseline in Percentage of Body Surface Area (BSA) Affected with Psoriasis at Week 12 and Week 52 [ Time Frame: Week 12 and Week 52 ]
    The percent of BSA affected (%BSA) is estimated by assuming that the participant's palm, excluding the fingers and thumb, represents roughly 1% of the body's surface.

  6. Number of participants With Treatment Emergent Adverse Events and Serious Adverse Events [ Time Frame: From Screening Day until Week 52 (EOS) ]
    Assessment of the safety of ABP 654 compared with ustekinumab.

  7. Events of Interests (EOIs) [ Time Frame: From Screening Day until Week 52 (EOS) ]
    Assessment of the safety of ABP 654 compared with ustekinumab.

  8. Number of Participants With Anti-drug Antibodies (ADAs) to ABP 654 [ Time Frame: Pre-dose on weeks 0 (day 1), 4, 12, 28, 32, 40, and on Week 52 (EOS) ]
    The detection and characterization of antibodies to ABP 654 will be performed.
