Subjects With Controlled Disease (i.e., Clear or Almost Clear) According to the Investigator's Global Assessment (IGA) of Disease Severity at Week 2

Disease severity of the scalp psoriasis as assessed by the 6-point scale IGA, based on the condition of the disease at the time of evaluation at week 2. The IGA Scale: 1 = clear, 2 = almost clear, 3 = mild, 4 = moderate, 5 = severe, and 6 = very severe.

Time frame: Week 2

Percentage Change in Total Sign Score (TSS; Sum of Severity Scores for Each Individual Clinical Sign, Redness, Thickness, and Scaliness)From Baseline to Week 2

Investigator assessment of scalp psoriasis lesions in terms of the three clinical signs: redness, thickness, and scaliness. Each clinical sign, a single score (ranging from 0 to 4), reflecting the average severity of all psoriatic lesions on the scalp, were determined. The sum of the three scores (redness, thickness, and scaliness) constitutes the Total Sign Score of the psoriasis on scalp, ranging from 0 (best possible outcome) to 12 points (worst possible outcome).
