What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Generalized Pustular Psoriasis (GPP) Achieving GPP Clinical Response at Week 16
Time Frame: Week 16
GPP Clinical Response defined as at least "Slightly Improved" in the overall improvement rating from baseline according to Japanese Dermatological Association (JDA) total score for GPP. The JDA consists of an assessment of skin symptoms (area of skin with erythema, pustules, and edema) on a scale of 0 (none) to 9 (severe) and a systemic symptoms/assessment of test findings (fever, white blood count [WBC], serum C-reactive protein [CRP], and serum albumin) on a scale of 0 (none) to 8 (severe). The JDA total score is the sum of the 2 assessments ranging from 0 (mild) to 17 (severe). The overall improvement rating ranges from Markedly improved (decreased by ≥ 3 points) to Worsened (increased by ≥ 1 point); Slightly improved represents no change in points and ≥ 20% and < 30% reduction of erythema area with pustules compared to baseline, or clinically meaningful improvement in ≥1 other parameters of the severity assessment criteria. Nonresponder imputation (NRI) was used for missing data.
Week 16
Percentage of Participants With Erythrodermic Psoriasis (EP) Achieving EP Clinical Response at Week 16
Time Frame: Week 16
EP Clinical Response, defined as at least "Minimally Improved" in Clinical Global Impression-Global Improvement (CGI-GI) for EP. The CGI-GI is a global assessment by the Investigator of the change in clinical status since the start of treatment. The CGI-GI ratings are as follows: 0 (not assessed), 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse), 7 (very much worse). NRI was used for missing data.
Week 16

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With GPP Achieving GPP Clinical Response at Week 52
Time Frame: Week 52
GPP Clinical Response defined as at least "Slightly Improved" in the overall improvement rating from baseline according to JDA total score for GPP. The JDA consists of an assessment of skin symptoms (area of skin with erythema, pustules, and edema) on a scale of 0 (none) to 9 (severe) and a systemic symptoms/assessment of test findings (fever, WBC, serum CRP, and serum albumin) on a scale of 0 (none) to 8 (severe). The JDA total score is the sum of the 2 assessments ranging from 0 (mild) to 17 (severe). The overall improvement rating ranges from Markedly improved (decreased by ≥ 3 points) to Worsened (increased by ≥ 1 point); Slightly improved represents no change in points and ≥ 20% and < 30% reduction of erythema area with pustules compared to baseline, or clinically meaningful improvement in ≥1 other parameters of the severity assessment criteria.
Week 52
Percentage of Participants With EP Achieving EP Clinical Response at Week 52
Time Frame: Week 52
EP Clinical Response, defined as at least "Minimally Improved" in CGI-GI for EP. The CGI-GI is a global assessment by the Investigator of the change in clinical status since the start of treatment. The CGI-GI ratings are as follows: 0 (not assessed), 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse), 7 (very much worse).
Week 52
Percentage of Participants With GPP Achieving 90% Improvement in Psoriasis Area and Severity Index (PASI) Score (PASI90) at Week 16
Time Frame: Week 16
PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline * 100.
