Physician Global Assessment of Psoriasis (PGA) is a 7-point scale used to assess severity of psoriatic plaques (1=severe psoriasis, 7=clear).

The analysis population was the modified intention-to-treat (mITT)population, which included all patients who received at least one dose of study drug and had at least 1 post-baseline evaluation. Last observation carried forward (LOCF).

Patients were asked to rate the severity of their psoriasis disease activity on a 6-point scale, where 0=good and 5=severe.

The analysis population was the modified intention-to-treat (mITT)population, which included all patients who received at least one dose of study drug and had at least 1 post-baseline evaluation. Last observation carried forward (LOCF).

Physician Global Assessment of Psoriasis (PGA) is a 7-point scale used to assess severity of psoriatic plaques (1=sever psoriasis, 7=clear). This assessment measured the time (in days) from baseline to the visit where a patient achieved a PGA status of 0 or 1. Patients who did not achieve this status by their last visit were not included.

The analysis population was the modified intention-to-treat (mITT) population, which included all patients who received at least one dose of study drug, had at least 1 post-baseline evaluation and who achieved a PGA status of 0 or 1 by the last visit (Observed cases).

Patients completed a patient satisfaction survey at baseline and throughout the study. Patients were asked to rate, based on their experienced during the past week, how satisfied or dissatisfied they were with their psoriasis therapy in general. Responses were based on a 7-point scale: Very satisfied, Satisfied, Somewhat Satisfied, Neutral, Somewhat Dissatisfied, Dissatisfied and Very Dissatisfied.
