A Study to Investigate ABP 654 for the Treatment of Participants With Moderate to Severe Plaque Psoriasis

Phase 3
Completed
Conditions
Plaque Psoriasis
Interventions
Registration Number
NCT04607980
Lead Sponsor
Amgen
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.

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.

GroupInterventionDescription
Treatment Group B (Ustekinumab - ABP 654)ABP 654Participants 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.
Treatment Group A (ABP 654)ABP 654Participants 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.
Treatment Group B (Ustekinumab - ABP 654)UstekinumabParticipants 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.
Primary Outcome Measures
NameTimeMethod
PASI Percent Change From Baseline to Week 12Baseline (Day 1 [Week 0]) and 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. Higher scores represent worse symptom severity.

Secondary Outcome Measures
NameTimeMethod
PASI Percent Change at Other TimepointsBaseline (Day 1 [Week 0]), Weeks 4, 16, 28, 36 (dose intensification only), 40 (re-randomized FAS only), 44 (dose intensification only) 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. Higher scores represent worse symptom severity.

Percentage of Participants With PASI 75 Response Throughout the StudyBaseline (Day 1 [Week 0]), Weeks 4, 16, 28, 36 (dose intensification only), 40 (re-randomized FAS only), 44 (dose intensification only) and Week 52 (EOS)

Reduction in disease was 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. Higher scores represent worse symptom severity.

Number of Participants Developing Anti-drug Antibodies (ADAs) to ABP 654Baseline; Day 1 (Week 0) to Week 28; Week 28 to Week 52 (EOS)

A participant was considered to have developed ADAs if they:

* had a positive post-baseline binding or neutralizing antibody result with a negative or no result at Baseline or

* had a positive post-baseline binding or neutralizing antibody result with a negative or no result prior to the first dose in the post Week 28 study period.

Change From Baseline in Percentage of BSA Affected With Psoriasis at Week 12 and Week 52Baseline (Day 1 [Week 0]), Week 12 and Week 52 (EOS)

The percentage of BSA affected was estimated by assuming that the participant's palm, excluding the fingers and thumb, represents roughly 1% of the body's surface.

Number of Participants With Events of Interests (EOIs)Day 1 (Week 0) to Week 28; Week 28 to Week 52 (EOS)

The EOIs pre-specified for this study included serious systemic hypersensitivity reactions, facial palsy, pustular psoriasis, erythrodermic psoriasis, serious infections (including mycobacterial and salmonella infections), malignancy, cardiovascular events, reversible posterior leukoencephalopathy syndrome, serious depression including suicidality, and venous thromboembolism.

Percentage of Participants With PASI 100 Response Throughout the StudyBaseline (Day 1 [Week 0]), Weeks 4, 16, 28, 36 (dose intensification only), 40 (re-randomized FAS only), 44 (dose intensification only) and Week 52 (EOS)

Reduction in disease was 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. Higher scores represent worse symptom severity.

Percentage of Participants With sPGA Responses (0/1) at Week 12 and Week 52Week 12 and Week 52 (EOS)

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 was defined as a sPGA value of clear (score 0) or almost clear (score 1). Higher scores represent worse symptom severity.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)Day 1 (Week 0) to Week 28; Week 28 to Week 52 (EOS)

TEAEs were summarized by actual treatment received. For each category, participants were included only once, even if they experienced multiple events in that category.
