Known active infection of any kind (excluding fungal infections of nail beds), any major episode of infection requiring hospitalization or treatment with intravenous (i.v.) anti infectives within 4 weeks of the Screening Visit Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2.5 times upper limit of normal (ULN) at Screening.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Percentage of Patients With at Least 75% Reduction in Psoriasis Area and Severity Index (PASI 75) Response at Week 16 | The PASI tool provides numeric scoring for a patient's overall psoriasis disease state, ranging from 0 to 72. Head (h), trunk (t), upper extremities (u) and lower extremities (l) areas were assessed; correspond to 10, 30, 20, and 40% of the total body area, respectively. The signs of severity, erythema (E), induration (I) and desquamation (D) of lesions were assessed using a numeric scale of 0 to 4 where 0 was a complete lack of cutaneous involvement and 4 was the severest possible involvement. The area of psoriatic involvement of these areas (Ah, At, Au, and Al) was given a numerical value: 0 = no involvement, 1 = <10%, 2 = 10 to <30%, 3 = 30 to <50%, 4 = 50 to <70%, 5 = 70 to <90%, and 6 = 90 to 100% involvement. PASI = 0.1(Eh+Ih+Dh)Ah + 0.3(Et+It+Dt)At + 0.2(Eu+Iu+Du)Au + 0.4(El+Il+Dl)Al. Percentage = least squares means per treatment groups back transformed using inverse logit function. | Week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Percentage of Patients With a PASI 75 Response at Week 24 | The PASI tool provides numeric scoring for a patient's overall psoriasis disease state, ranging from 0 to 72. Head (h), trunk (t), upper extremities (u) and lower extremities (l) areas were assessed; correspond to 10, 30, 20, and 40% of the total body area, respectively. The signs of severity, erythema (E), induration (I) and desquamation (D) of lesions were assessed using a numeric scale of 0 to 4 where 0 was a complete lack of cutaneous involvement and 4 was the severest possible involvement. The area of psoriatic involvement of these areas (Ah, At, Au, and Al) was given a numerical value: 0 = no involvement, 1 = <10%, 2 = 10 to <30%, 3 = 30 to <50%, 4 = 50 to <70%, 5 = 70 to <90%, and 6 = 90 to 100% involvement. PASI = 0.1(Eh+Ih+Dh)Ah + 0.3(Et+It+Dt)At + 0.2(Eu+Iu+Du)Au + 0.4(El+Il+Dl)Al. Percentage = least squares means per treatment groups back transformed using inverse logit function. | Week 24 | 
| The Mean Percentage Improvement in PASI at Week 16 | The PASI tool provides numeric scoring for a patient's overall psoriasis disease state, ranging from 0 to 72. Head (h), trunk (t), upper extremities (u) and lower extremities (l) areas were assessed; correspond to 10, 30, 20, and 40% of the total body area, respectively. The signs of severity, erythema (E), induration (I) and desquamation (D) of lesions were assessed using a numeric scale of 0 to 4 where 0 was a complete lack of cutaneous involvement and 4 was the severest possible involvement. The area of psoriatic involvement of these areas (Ah, At, Au, and Al) was given a numerical value: 0 = no involvement, 1 =<10%, 2 =10 to <30%, 3 =30 to <50%, 4 =50 to <70%, 5 =70 to <90%, and 6 =90 to 100% involvement. PASI = 0.1(Eh+Ih+Dh)Ah + 0.3(Et+It+Dt)At + 0.2(Eu+Iu+Du)Au + 0.4(El+Il+Dl)Al. Results based on PASI mean percentage improvement from Baseline after 16 weeks of treatment = overall mean + treatment group + Baseline PASI + prior exposure to a biological agent + random error. | Week 16 | 
| The Percentage of Patients With a Static Physician's Global Assessment (sPGA) ≤1 (Clear or Almost Clear) at Week 16 | The Static Physician's Global Assessment (sPGA) is a 5-point score ranging from 0 to 4, based on the physician's assessment of the average thickness, erythema, and scaling of all psoriatic lesions. The assessment was considered static, which referred to the patient's disease state at the time of the assessment, without comparison to any of the patient's previous disease states (dynamic), whether at Baseline or at a previous visit. A lower score indicated less body coverage, with 0 being clear, 1 being almost clear, and 4 being. Percentage = least squares means per treatment groups back transformed using inverse logit function. | Week 16 | 
| The Percentage of Patients Achieving a Dermatology Life Quality Index (DLQI) of 0 or 1 at Week 16 | The DLQI is a subject-administered, 10-question, that covers 6 domains including symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment. It has a 1-week recall period. Every item score ranges from 0 (not relevant/not at all) to 3 (very much). Question 7 is a yes/no question where yes is scored as 3. The DLQI total score was calculated by summing the scores of each question resulting in a range of 0 to 30 where 0-1 = no effect on subject's life, 2-5 = small effect, 6-10 = moderate effect, 11-20 = very large effect, and 21-30 = extremely large effect on the subject's life. The higher the score, the more the quality of life is impaired. If the answer to 1 question in a domain was missing, that domain was treated as missing. If 2 or more questions were left unanswered (missing), DLQI total score was treated as missing. Percentage = least squares means per treatment groups back transformed using inverse logit function. | Week 16 | 
| The Percentage of Patients With Drug-related Adverse Events (AEs) | The secondary safety endpoint was defined as the percentage of patients with drug-related adverse events (AEs). | From first drug administration until 10 weeks after last drug administration, up to 34 weeks. |
