Detaljert beskrivelse

Psoriasis is a chronic immune disease of the skin and joints that affects about 2% of the population. The most common form of psoriasis is plaque psoriasis, also called psoriasis vulgaris. A variety of drugs, including biologics, are available for treatment of moderate to severe psoriasis. When biologic agents are stopped, psoriasis can return (relapse) and often requires the biologic to be restarted and continued. No treatment program has been identified to prevent relapse of psoriasis.

The study design has a lead-in period of weight-based ustekinumab treatment, with all participants receiving either 45 mg ustekinumab (<= 100 kg) or 90 mg ustekinumab (> 100 kg) administered subcutaneously at weeks 0 and 4. At week 12, participants will be assessed for a Psoriasis Area and Severity Index (PASI) 75 response to ustekinumab. Participants who do not achieve a PASI 75 score will be discontinued from the investigation and permitted to seek standard therapy.

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Percentage of Participants Who Experienced Psoriasis Relapse (Treating Drop-Outs as Relapse)
Tidsramme: Post-randomization (Week 12 to 88)
The percentage of participants who experienced psoriasis relapse in the interval from Week 12 to 88. Psoriasis relapse is defined as loss of ≥ 50% of the initial Psoriasis Area and Severity Index (PASI) improvement measured at Week 12. This occurs if the participant obtains a PASI score at any evaluation during the specified time interval that is ≥ Week 12 PASI + [(Baseline PASI -Week 12 PASI)/2]). Participants who terminated early from the study (drop-outs) were considered to have experienced relapse at time of drop-out. PASI is an assessment for psoriasis severity based on 4 body areas: Head and Neck, Upper Extremities, Trunk, and Lower Extremities. Psoriasis severity within each body area is assessed for Redness (score 0-4), Thickness (score 0-4) and Scaling (score 0-4). Scores for each body area are summed and weighted by the affected Body Surface Area (score 0-6) to produce the total score. The score ranges from 0 (no psoriasis present) to 72 (very severe psoriasis).

Tidsramme: Week 40, Week 88
Percentage of participants who were classified as cleared or minimal in the Physician's Global Assessment (PGA) average score at the specified post-randomization time point. The PGA assesses the severity of the psoriasis in 3 components: induration, erythema and scaling. Each component is given a score ranging from 0 to 5 based on the majority of the participant's psoriasis lesions, with higher scores indicating worse disease. A PGA average score < 1.5 was classified as "cleared or minimal."
Week 40, Week 88
Change in Dermatology Life Quality Index (DLQI)
Tidsramme: Week 40, Week 88
Change in the Dermatology Life Quality Index (DLQI) score from Week 12 to the specified post-randomization time point. DLQI is a 10-question, participant-reported questionnaire that assesses quality of life with respect to skin conditions in the areas of symptoms and feelings, daily activities, leisure, work and school, personal relationships and treatment. Each question measures the level of effect that the skin condition has on quality of life, and responses range from 'Not at all' (score = 0) to 'Very much' (score = 3). The overall score is the sum of the scores for all 10 questions and ranges from 0-30, with higher scores indicating worse quality of life.

Frequency and Severity of Adverse Events and Serious Adverse Events (By Participant, Lead-in Phase)
Tidsramme: Lead-In Phase (Week 0 to 12)
Number of participants who experienced adverse events (AEs) during the lead-in phase (Week 0 to 12), classified by severity and type. AEs were classified by grade according to the National Cancer Institute's (NCI's) Common Toxicity Criteria for Adverse Events (CTCAE) version 4.03, and all Grade 2 or greater AEs were collected in the database. In addition, new onset or worsening psoriatic arthritis was separately collected and graded from 1 to 3 along a study-specific functional scale. AEs were also classified based on relatedness to study drug, whether they led to study drug discontinuation, and whether they were AEs of special interest as specified in the protocol.
