PRIMARY outcome

Timeframe: 128 weeks

Population: Due to the early termination of the study, no subjects completed 128 weeks of therapy.

PASI75 defined as the number of participants who achieved a \>=75% improvement in Psoriasis Area and Severity Index (PASI) from the original Baseline in Study P04271 (NCT00251641).

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 52 weeks

Population: Descriptive summary of all randomized subjects who completed 52 weeks (+ or - 4 weeks) of therapy. Based on best (minimum) PASI score at Week 52.

SECONDARY outcome

Timeframe: Day 0 to 180 days

Population: Participants with at least two post Study P04563 randomization PASI scores (at least one is 150 days or more from Study P04563 randomization).

The PASI 6-month AUC is a time adjusted total PASI score over the 6 month (180 days) period. The AUC is a continuous measurement (not a score on a scale); a lower value is considered better and a higher value is considered worse. The weighted average PASI score over 6 months (using all available PASI scores during a 6 month period \[from Day 0 to 180 days\]) is obtained by using PASI 6-month AUC /180 days.

SECONDARY outcome

Timeframe: Day 0 to 360 days

Population: Participants with at least two post Study P04563 randomization PASI scores (at least one is 330 days or more from Study P04563 randomization).

The PASI 12-month AUC is a time adjusted total PASI score over the 12 month (360 days) period. The AUC is a continuous measurement (not a score on a scale); and a lower value is considered better. The weighted average PASI score over 12 months (using all available PASI scores during a 12 month period \[from Day 0 to 360 days\]) is is obtained by using PASI 12-month AUC /360 days.
