Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patients With "Controlled Disease" in Terms of "Clear" or "Minimal" According to Investigator's Global Assessment of Disease Severity at Week 4.	Investigators made a global assessment of the disease severity by use of a 6-point scale (Clear, Minimal, Mild, Moderate, Severe and Very Severe). Patients with disease severity classified as Clear or Minimal disease after the treatment period (week 4) were rated as having Controlled disease.	4 weeks	No
Secondary	Patients With "Controlled Disease" in Terms of "Clear" or "Minimal" According to Investigator's Global Assessment of Disease Severity at Week 2	Investigators made a global assessment of the disease severity by use of a 6-point scale (Clear, Minimal, Mild, Moderate, Severe and Very Severe). Patients with disease severity classified as Clear or Minimal disease at week 2 were rated as having Controlled disease.	2 weeks	No
Secondary	Patients With "Controlled Disease" in Terms of "Clear" or "Very Mild" According to Patient's Global Assessment of Disease Severity at Week 2.	Patients made a global assessment of the disease severity by use of a 5-point scale (Clear, Very Mild, Mild, Moderate, Severe). Patients classifying their disease as Clear or Very Mild at week 2 were rated as having Controlled disease. This assessment was made prior to the investigator's assessments.	2 weeks	No
Secondary	Patients With "Controlled Disease" in Term of "Clear" or "Very Mild" According to Patient's Global Assessment of Disease Severity at Week 4.	Patients made a global assessment of the disease severity by use of a 5-point scale (Clear, Very Mild, Mild, Moderate, Severe). Patients classifying their disease as Clear or Very Mild at week 4 were rated as having Controlled disease. This assessment was made prior to the investigator's assessments.	4 weeks	No
Secondary	Patients With Success (Total Sign Score =1) at Week 4	Investigators assessed scalp psoriasis lesions in terms of three clinical signs: redness, thickness and scaliness. For each clinical sign a single score, reflecting the average severity of all lesions on the scalp, was derived according to a 5-point scale ranging from 0 to 4 (0= best;4= worst). The sum of the three individual scores (redness, thickness and scaliness) constituted a Total Sign Score of the scalp ranging from 0 to 12 (0= best;12= worst). Patients with a Total sign score of 0 or 1 at week 4 achieved "Success".	4 weeks	No
Secondary	For Each Clinical Sign (Redness, Thickness, Scaliness), the Percentage of Patients With Success (Clinical Score=0) at Week 4		4 weeks	No
Secondary	Patients With Success (Patient's Itching Score=None) at Week 4		4 weeks	No
Secondary	Evaluation of the Quality of Life		Baseline to weeks 2 and 4	No
