Visits will consist of Baseline, 8 week, 16 week and a 20 week safety follow up after 4 weeks off treatment. Subjects will dose with apremilast as per label. Topical corticosteroids (TCS) will be used for up to Week 4 as per label and then will be used on an as needed basis until Week 16. Assessments will include Static Physicians Global Assessment (sPGA), Psoriasis Area Severity Index (PASI), Psoriatic Body Surface Area (BSA), Dermatology Life Quality Index (DLQI),Assessment of Pruritus, Patient Satisfaction questionnaire. and Patient Global Assessment (PtGA)

Primary Outcome Measures

Name	Time	Method
Mean Change in Product of BSA (Body Surface Affected by Psoriasis) and sPGA (Static Physician Global Assessment) From Baseline to Week 16	Week 16	The area of body surface affected by psoriasis (BSA) will be estimated by the Investigator as a percentage of the subject's total body surface area wherein the area of the subject's palm will be considered as 1% of total BSA. Static Physician Global Assessment (sPGA) of disease severity is measured by the Investigator on a 6-point scale wherein 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, 4=Severe, 5=Very Severe. The product of these values offers a more specific assessment of the severity of psoriasis. This product can yield a result between 0 (no disease) and 500 (most severe disease) By reporting the percent change as well as the absolute value change, the reader may be better able to appreciate the impact on disease severity of the medication under study.

Static Physician Global Assessment (sPGA) is measured by the Investigator on a 6-point scale wherein 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, 4=Severe, 5=Very Severe.

Secondary Outcome Measures

Name	Time	Method
Percent Change in Product of BSA and sPGA	Week 8	The area of body surface affected by psoriasis (BSA) will be estimated by the Investigator as a percentage of the subject's total body surface area wherein the area of the subject's palm will be considered as 1% of total BSA. Static Physician Global Assessment (sPGA) is measured by the Investigator on a 6-point scale wherein 0=Clear, 1=Almost Clear, 2=Mild, 3=Moderate, 4=Severe, 5=Very Severe. Th3 product of these values offers a more specific assessment of the severity of psoriasis. This product may yield a result between 0 (no disease) and 500 (most severe disease.)
Mean Change in DLQI	Week 16	The Dermatology Life Quality Index (DLQI) is a 10-question survey administered to subjects in order to ascertain the extent to which psoriasis has affected the patient's life in the week prior to completing the questionnaire. The score is a sum of the value of each answer wherein Very Much=3, A lot=2, A little=1 and Not at all=0. 0 is the lowest possible score and indicates no impact of disease on quality of life. 30 is the highest possible score and indicates the most negative impact of disease on quality of life.
Mean Change in Pruritus Scores	Baseline to Week 16	The Subject Assessments of pruritis is measured at screening, baseline, and weeks 4, 8 and 16. Each subject rates the severity of their itching over the last 24 hours on a 10-point scale from 0 (none) to 10 (unbearable)
Mean Change in BSA	Week 16	The area of body surface affected by psoriasis (BSA) will be estimated by the Investigator as a percentage of the subject's total body surface area wherein the area of the subject's palm will be considered as 1% of total BSA. This will be assessed at screening, baseline, and weeks 4, 8 and 16
Proportion of Patients Who Achieve PASI 50	Week 16	The Psoriasis Area Severity index (PASI) is performed at screening, baseline, and weeks 4, 8 and 16. This tool is used to measure the severity and extent of disease by combining the assessment of severity of lesions and the area affected into a single score in the range of 0 (no disease) to 72 (maximal disease.)
Percent Change in BSA	Baseline to Week 16	The area of body surface affected by psoriasis (BSA) will be estimated by the Investigator as a percentage of the subject's total body surface area wherein the area of the subject's palm will be considered as 1% of total BSA. This will be assessed at screening, baseline, and weeks 4, 8 and 16
Proportion of Patients Who Achieve PASI 75	Week 16	The Psoriasis Area Severity index (PASI) is performed at screening, baseline, and weeks 4, 8 and 16. This tool is used to measure the severity and extent of disease by combining the assessment of severity of lesions and the area affected into a single score in the range of 0 (no disease) to 72 (maximal disease.)
% of Patients Achieving Clear or Almost Clear on the PtGA	Week 16	The Psoriasis Area Severity index (PASI) is performed at screening, baseline, and weeks 4, 8 and 16. This tool is used to measure the severity and extent of disease by combining the assessment of severity of lesions and the area affected into a single score in the range of 0 (no disease) to 72 (maximal disease.)
