Detaljeret beskrivelse

In Part A1, eligible participants were randomized at Baseline at a ratio of 4:1, stratified by weight and prior exposure to tumor necrosis factor antagonists to receive double-blind (DB) risankizumab 150 mg or placebo at Weeks 0 and 4. In Part A2, participants randomized at Baseline to receive DB placebo then received risankizumab 150 mg at Weeks 16 (Part A2) and at Week 28 and every 12 weeks up to 88 weeks (Part B); participants randomized to risankizumab 150 mg continued to receive risankizumab 150 mg at Week 16. Participants who received risankizumab in Part A and were nonresponders (sPGA >2) at Week 28 received risankizumab 150 mg at Week 28 and every 12 weeks up to 88 weeks (Part B). In Part B, participants who received risankizumab in Part A and were responders (sPGA ≤2) at Week 28, were rerandomized at a ratio of 1:2 to receive DB risankizumab 150 mg or placebo at Week 28 and every 12 weeks up to 88 weeks (Part B). Starting at Week 32, rerandomized participants who reached relapse (defined as sPGA ≥3) were switched to risankizumab 150 mg every 12 weeks.

Exclusion criteria:

  • Participants with nonplaque forms of psoriasis (including guttate, erythrodermic, or pustular); current drug-induced psoriasis (including a new onset of psoriasis or an exacerbation of psoriasis from beta blockers, calcium channel blockers, or lithium); active ongoing inflammatory diseases other than psoriasis and psoriatic arthritis that might confound trial evaluations according to the investigators judgment.

  • Evidence of a current or previous disease (including chronic alcohol or drug abuse), medical condition other than psoriasis, surgical procedure (i.e., organ transplant), medical examination finding (including vital signs and electrocardiogram [ECG]), or laboratory value at the screening visit outside the reference range that in the opinion of the Investigator, is clinically significant and would make the study participant unable to adhere to the protocol or to complete the trial, compromise the safety of the patient, or compromise the quality of the data.
  • History of allergy/hypersensitivity to a systemically administered biologic agent or its excipients
  • Women who are pregnant, nursing, or who plan to become pregnant while in the trial

Foranstaltningsbeskrivelse
Tidsramme
Percentage of Participants Achieving 90% Improvement Psoriasis Area and Severity Index (PASI) Score (PASI90) From Baseline to Week 16
Tidsramme: Baseline, Week 16
PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline * 100. Non-responder imputation (NRI) was used for missing data.
Baseline, Week 16
Percentage of Participants Achieving Static Physician Global Assessment (sPGA) Score of Clear or Almost Clear at Week 16
Tidsramme: Week 16
The sPGA is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA ranges from 0 to 4, and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean >0, <1.5; Mild (2) = mean ≥1.5, <2.5; Moderate (3) = mean ≥2.5, <3.5; and Severe (4) = mean ≥3.5. NRI was used for missing data.

Percentage of Participants Achieving sPGA Score of Clear or Almost Clear at Week 52
Tidsramme: Week 52
The sPGA is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe).

Tidsramme
Procentdel af deltagere, der opnår 75 % forbedring i PASI-score (PASI75) i uge 16
Tidsramme: Uge 16
PASI er en sammensat score baseret på graden af ​​effekt på kropsoverfladearealet af psoriasis og udvidelsen af ​​erytem (rødmen), induration (tykkelse), afskalning (afskalning) af læsionerne og det påvirkede område som observeret på undersøgelsesdagen. Sværhedsgraden af ​​hvert tegn blev vurderet ved hjælp af en 5-punkts skala, hvor 0 = ingen symptomer, 1 = let, 2 = moderat, 3 = markant, 4 = meget markant. PASI-scoren går fra 0 til 72, hvor 0 indikerer ingen psoriasis og 72 indikerer meget svær psoriasis. PASI75 er defineret som en reduktion på mindst 75 % i PASI-score sammenlignet med Baseline PASI-score. Den procentvise reduktion i score beregnes som (PASI-score ved baseline - score ved opfølgningsbesøg) / PASI-score ved baseline * 100. NRI blev brugt til manglende data.

The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI100 is defined as a 100% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline * 100. NRI was used for missing data.

Percentage of Participants Achieving an sPGA Score of Clear at Week 16
Tidsramme: Week 16
The sPGA is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA ranges from 0 to 4, and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean >0, <1.5; Mild (2) = mean ≥1.5, <2.5; Moderate (3) = mean ≥2.5, <3.5; and Severe (4) = mean ≥3.5. NRI was used for missing data.
Week 16
Percentage of Participants Achieving a Dermatology Life Quality Index (DLQI) Score of 0 or 1 at Week 16
Tidsramme: Week 16
The DLQI is a 10-question questionnaire that asks the participant to evaluate the degree that psoriasis has affected their quality of life in the last week and includes 6 domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment). Responses to each domain are not relevant (0), not at all (0), a little (1), a lot (2), and very much (3). The DLQI is calculated by summing the scores of the questions and ranges from 1 to 30, where 0-1 = no effect on patient's life, 2-5 = small effect, 6-10 = moderate effect, 11-20 = very large effect, and 21-30 = extremely large effect on patient's life. The higher the score, the more the quality of life is impaired. NRI was used for missing data.
