PRIMARY outcome

Timeframe: Month 12

Population: Full Analysis Set, composed of enrolled participants who received at least one dose of study medication and who had a baseline and at least one post-baseline measurement of the endpoint of interest. Missing post-baseline values were imputed using last observation carried forward.

The number of participants with a status of mild or better (score of 0, 1 or 2) on the Physician Global Assessment (PGA) of psoriasis at Month 12. This scale ranges from 0 to 5, with 0 = best outcome.

SECONDARY outcome

Timeframe: Baseline and Month 12

Population: Full Analysis Set, composed of enrolled participants who received at least one dose of study medication and who had a baseline and at least one post-baseline measurement of the endpoint of interest, with imputation using Last Observation Carried Forward (LOCF).

Percent change from Baseline to Month 12 in the Patient Global Assessment of psoriasis score. This score ranged from 0 (good) to 5 (severe). A negative change from Baseline indicates improvement in disease activity.

SECONDARY outcome

Timeframe: Baseline and Month 12

Population: Full Analysis Set, composed of enrolled participants who received at least one dose of study medication and who had a baseline and at least one post-baseline measurement of the endpoint of interest, with imputation using Last Observation Carried Forward (LOCF).

Percent change from Baseline to Month 12 in body surface area (BSA) affected by psoriasis. A reduction (indicated by a negative percent change from Baseline) in the BSA affected is indicative of improvement in disease activity.

Timeframe: Baseline and Month 12

Population: Full Analysis Set, composed of enrolled participants who received at least one dose of study medication and who had a baseline and at least one post-baseline measurement of the endpoint of interest, with imputation using Last Observation Carried Forward (LOCF).

Percent change from Baseline to Month 12 in the Dermatology Life Quality Index (DLQI) total score. This score ranges from 0 to 30, where 0 = no effect and 30 = large effect. A reduction in DLQI total score is indicative of improvement in quality of life as it relates to the participant's psoriasis, and a negative change from Baseline indicates improvement.
