What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With Psoriasis Area and Severity Index (PASI) 75 Response at 16 Weeks	PASI 75 is a 75% or greater improvement on the Psoriasis Area and Severity Index (PASI). The PASI scale runs from 0-72, where 0 = no psoriasis and 72 = complete erythroderma of the severest possible degree	16 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at 16 and 24 Weeks	Mean change in Psoriasis Area and Severity Index (PASI) score from Baseline. PASI score ranges from 0-72, where 0 = no psoriasis and 72 = complete erythroderma of the severest possible degree	16 and 24 weeks
Mean Percent Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at 16 and 24 Weeks	Mean percent change in Psoriasis Area and Severity Index (PASI) score from Baseline. PASI score ranges from 0-72, where 0 = no psoriasis and 72 = complete erythroderma of the severest possible degree.	16 and 24 weeks
Number of Subjects With Improvement in Physician's Global Assessment for Psoriasis (PGA)	Number of subjects with improvement on the Physician's Global Assessment for Psoriasis (PGA). The PGA is a 6-point scale used to measure the severity of disease at the time of the physician's evaluation of the subject, where 0 = clear and 6 = very severe. Improvement is defined as a reduction in PGA score.	16 and 24 weeks
Number of Subjects Achieving a Clinical Response Defined as a Physician's Global Assessment for Psoriasis (PGA) of "Clear" or "Clear or Minimal"	Number of subjects achieving a response of "Clear" or "Clear or Minimal" on the Physician's Global Assessment for Psoriasis. This is a 6-point scale used to measure the severity of disease at the time of the physician's evaluation of the subject. The degree of overall severity is rated as follows: 0-Clear, 1-Minimal, 2-Mild, 3-Moderate, 4-severe, 5-very severe.	16 and 24 weeks
Mean Change From Baseline in Physician Global Assessment of Arthritic Disease Activity at 16 and 24 Weeks	Mean Change from Baseline in Physician Global Assessment of Arthritic Disease Activity as measured on a 100-mm visual analog scale where 0 mm = no arthritis activity and 100 mm = extremely active arthritis.	16 and 24 weeks
Number of Subjects With Psoriasis Area and Severity Index (PASI) 50/75/90/100 Response	PASI 50/75/90/100 is a >=50% / >=75% / >=90% / 100% improvement on the Psoriasis Area and Severity Index (PASI). The PASI scale runs from 0-72, where 0 = no psoriasis and 72 = complete erythroderma of the severest possible degree.	16 and 24 weeks
Mean Change From Baseline in Tender Joint Count at 16 and 24 Weeks	Mean change in the number of tender joints from Baseline. 78 joints were evaluated for tenderness, including all 76 joints evaluated for swelling plus the hip joints.	16 and 24 weeks
Mean Change From Baseline in Swollen Joint Count at 16 and 24 Weeks	Mean change in the number of swollen joints from Baseline. 76 joints were evaluated for swelling, corresponding to all joints evaluated for tenderness except for the hip joints.	16 and 24 weeks
Mean Change From Baseline in Patient's Global Assessment of Joint Pain at 16 and 24 Weeks	Mean change in the Patient's Global Assessment of Joint Pain from Baseline, as assessed on a 100-mm visual analog scale where 0 mm = no pain and 100 mm = pain as bad as it could be.	16 and 24 weeks
Mean Change From Baseline in the Dermatology Life Quality Index (DLQI) at 16 and 24 Weeks	Mean change in the Dermatology Life Quality Index (DLQI) from Baseline. The questionnaire contains 10 questions and is scored from 0-30, where 0 = total lack of impairment and 30 = my life is very much impaired; the minimum clinically important difference is 2.3 to 5.7 point change.	16 and 24 weeks
Number of Subjects Achieving a Dermatology Life Quality Index (DLQI) = 0	Number of subjects achieving a Dermatology Life Quality Index (DLQI) score of 0 (indicating total lack of impairment). The DLQI consists of 10 questions and is scored from 0-30, where 0 = total lack of impairment and 30 = my life is very much impaired.	16 and 24 weeks
Mean Change From Baseline in Beck Depression Inventory (BDI-II) at 16 and 24 Weeks	Change in the Beck Depression Inventory from Baseline. The BDI-II contains 21 questions and is scored from 0-63; higher scores indicate more severe depression symptoms.	16 and 24 weeks
