Efficacy, Safety, and Immunogenicity of BI 695501 Versus Humira® in Patients With Moderate to Severe Chronic Plaque Psoriasis: A Randomized, Double-Blind, Parallel-Arm, Multiple-Dose, Active Comparator Trial

The Percentage of Patients With at Least 75% Reduction in Psoriasis Area and Severity Index (PASI 75) Response at Week 16

时间窗: 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.
