Descrição detalhada

This is a multicenter (involving more than 1 study center), randomized (study medication assigned by chance), double-blind (neither the invesitigator nor the participant knows the identity of the study medication), placebo- controlled (1 of the study medications is inactive), parallel-group comparative study (different groups of participants will receive different treatments at the same time). The total duration of the study will be 78 weeks which will be comprised of: a screening period (6 weeks); an efficacy assessment period (64 weeks [with a total of 7 treatments at Weeks 0, 4, 12, 16, 28, 40, and 52]) and a follow-up assessment period (8 weeks). The efficacy assessment period will further include: a placebo-controlled treatment period (Weeks 0-12) and an active drug treatment period (Weeks 12-64). During the placebo-controlled treatment period, participants will receive ustekinumab (45 mg or 90 mg) subcutaneously (SC-into the muscles) or placebo SC. During the active drug treatment period, participants will continue treatment with 45 mg or 90 mg SC as assigned during the placebo-controlled treatment period; however, participants in the placebo group will be divided into 2 groups and will receive ustekinumab 45 mg (Placebo A) or 90 mg (Placebo B) SC. Efficacy will be evaluated primarily by analysis of psoriasis area and severity index (PASI) score. Participant safety will also be monitored.

The scale ranges from 0 (best) to 72 (worst). Percentage of Treatment Response= (Baseline PASI score-PASI score after treatment)/Baseline PASI score x 100. Baseline visit refers to Week 0.
Week 64
Change From Baseline in Dermatology Life Quality Index (DLQI) Score at Week 28, 40, 52 and 64
Prazo: Week 28, 40, 52 and 64
The DLQI is a self-administered 10-item questionnaire that is used to assess 6 different aspects of quality of life: symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment.

The SF-36 is a validated instrument measuring health-related quality of life across multiple disease states. It has 36 questions with 8 subscale scores and 2 summary scores: (1) physical component summary (PCS)=physical functioning, role-physical, bodily pain, and general health; (2) mental component summary (MCS)=vitality, social functioning, role-emotional, and mental health. There is no total overall score; scoring is done for both sub scores and summary scores. For sub scores and summary scores: 0=worst score and 100=best score.

The PDI questionnaire consists of 15 questions relating to the impact of psoriasis in terms of daily activities, work or school, personal relationships, leisure, and treatment. Each question is scored on a scale of 0 (no impact) to 3 (greatest impact). The PDI is calculated by summing the scores of the questions resulting in a maximum score of 45 (greatest impact) and a minimum score of 0 (no impact).

Treatment Response Based on Nail Psoriasis Severity Index (NAPSI) Score
Prazo: Week 12, 28, 40,52 and 64
The NAPSI score is used to evaluate the severity of nail bed psoriasis and nail matrix psoriasis. The nail is divided with into quadrants and given a score for nail bed psoriasis (0-4) and nail matrix psoriasis (0-4) depending on the presence of any of the features of nail psoriasis in that quadrant. Each nail is evaluated, and the sum of all the nails is the total NAPSI score. The sum of the scores from all nails ranges from 0 (no psoriasis) to 80 (psoriasis present in all 4 quadrants of all 10 nails).

The PGA score is a numeric scale which is completed by the physician and is designed to evaluate the physician's overall assessment of the participant's psoriasis. Overall lesions will be graded for induration (I), erythema (E), and scaling (S) as: 0=cleared, 1=minimal, 2=mild, 3=moderate, 4=marked, and 5=severe. The sum of the 3 scores (I + E + S) will be divided by 3 to obtain a final PGA score ranging from 0 [best] to 5 [worst].
