Yksityiskohtainen kuvaus
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.

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).

Percentage of participants with PGA score of cleared (0), cleared or minimal (0 or 1) and mild (less than or equal to 2) was reported.
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].
