Group Intervention Description adalimumab-EU source Adalimumab Participants received 80 mg adalimumab subcutaneously on week 1/day 1 (initial loading dose) and 40 mg at week 2 and every 2 weeks thereafter until week 16. At week 16 participants with a PASI 50 response were re-randomized to treatment with adalimumab or were transitioned to SCT630 until week 48 SCT630 SCT630 Participants received 80 mg SCT630 subcutaneously on week 1/day 1 (initial loading dose) and 40 mg at week 2 and every 2 weeks thereafter until week 16. Participants with a PASI 50 response at week 16 continued to receive 40 mg SCT630 until week 48.
- Primary Outcome Measures
Name Time Method Percent Improvement From Baseline in Psoriasis Area and Severity Index (PASI) at Week 16 Baseline and Week 16 The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.
Percent improvement from baseline was calculated as (value at baseline - value at post-baseline visit) × 100 / (value at baseline).
- Secondary Outcome Measures
Name Time Method Percent Improvement From Baseline in PASI at Week 4、8、12、24、32、48、50 Baseline and week 4、8、12、24、32、48、50 The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.
Percent improvement from baseline is calculated as (value at baseline - value at post-baseline visit) × 100 / (value at baseline).Change From Baseline in the Percentage of Body Surface Area (BSA) Involved With Psoriasis at Week 4、8、12、16、24、32、48、50 Baseline and Week 4、8、12、16、24、32、48、50 A measurement of psoriasis involvement, given as the physician's assessment of the percentage of the participant's total body surface area (BSA) involved with psoriasis. The percent of BSA affected was estimated by assuming that the subject's palm, excluding the fingers and thumb, represented roughly 1% of the body's surface.
Change from baseline is calculated as (value at post-baseline visit - value at baseline).
A decrease from baseline (negative value) indicates improvement.Change From Baseline of dermatology life quality index (DLQI)at Week 4、8、12、16、24、32、48、50 Baseline and Week 4、8、12、16、24、32、48、50 Percentage of Participants With a PASI 90 Response at Week 4、8、12、16、24、32、48、50 Baseline and Week 4、8、12、16、24、32、48、50 A PASI 90 response is a 90% or greater improvement (reduction) from baseline in PASI score. The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.
Percentage of Participants With a PASI 50 Response at Week 4、8、12、16、24、32、48、50 Baseline and Week 4、8、12、16、24、32、48、50 A PASI 50 response is a 50% or greater improvement (reduction) from baseline in PASI score. The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.
Percentage of Participants With a PASI 75 Response at Week 4、8、12、16、24、32、48、50 Baseline and Week 4、8、12、16、24、32、48、50 A PASI 75 response is a 75% or greater improvement (reduction) from baseline in PASI score. The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.

The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.
