Primary Outcome Measures

Name	Time	Method
Percentage of Participants Who Achieved a 75% Reduction in Psoriasis Area and Severity Index (PASI) (PASI 75) Scores at Week 16	Baseline; Week 16	The PASI combines assessments of the extent of body surface involvement in 4 anatomical regions (head, arms, trunk, and legs) and the severity of scaling, redness, and thickness in each region, yielding an overall score of 0 for no disease to 72 for the most severe disease. Each of the body areas was scored by itself, and then the 4 scores were combined into the final PASI score. Participants achieving PASI 75 are defined as having an improvement (reduction) of at least 75% in the Week 16 PASI score compared to the score at Baseline.

Secondary Outcome Measures

Name	Time	Method
Immunogenicity: Number of Participants With ADA at Week 25	Week 25	The M923 confirmation assay was evaluated only if the EU Humira confirmation assay was negative. Overall Result: a participant was considered to be positive if a confirmed positive result was observed at any assay (including predose; if a participant had either a negative result in the screening assay or a positive result at screening followed by a negative result in all confirmation tiers, the overall result was negative. Overall Status: a participant was considered to have developed ADA or neutralizing ADAs if a confirmed positive result was observed at any time during the treatment period inclusive of the predose results; the designation of negative required either a negative screening assay or a negative confirmation result at each sampling time. The same convention applied for the neutralizing assay results.
Percentage of Participants With a Response of Clear or Almost Clear on the Static Physician Global Assessment (sPGA) at Week 16	Week 16	The sPGA response rate was defined as the percentage of participants who had achieved a clear or almost clear response on the 6-point sPGA scale. The sPGA was the physician's determination of the participant's psoriasis lesions overall at a given time point. Overall lesions were categorized by descriptions for induration, erythema, and scaling. For the analysis of responses, the participant's psoriasis was assessed at a given time point on a 6-point scale on which 0 = cleared, 1 = minimal, 2 = mild, 3 = moderate, 4 = severe, and 5 = very severe.

Health-Related Quality of Life During Treatment: Dermatology Life Quality Index (DLQI) Score at Baseline	Baseline	The DLQI score was calculated by summing the individual scores of each question at a given time point, resulting in a maximum score of 30 and a minimum score of 0.

For the analysis of responses, the participant's results were assessed on a scoring scale on which 3 = very much or yes (applicable to question 7 only), 2 = a lot, 1 = a little, 0 = not at all or not relevant. Interpretation of DLQI scoring can be taken as 0 - 1 = no effect at all on participant's life, 2 - 5 = small effect on participant's life, 6 - 10 = moderate effect on participant's life, 11 - 20 = very large effect on participant's life, and 21 - 30 = extremely large effect on participant's life.

For the analysis of responses, the participant's results were assessed on a scoring scale on which 3 = very much or yes (applicable to question 7 only), 2 = a lot, 1 = a little, 0 = not at all or not relevant.
