Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of subjects achieving PASI 90 response | Week 12 | The PASI75 response assessments are based on at least 90% improvement in PASI score from Baseline. |
| Proportion of subjects achieving sPGA 0/1 | Week 12 | The sPGA is a physician's determination of the participant's psoriasis lesions overall at a given time point categorized by descriptions for induration, erythema, and scaling. For the analysis of responses, the participant's psoriasis is assessed as clear (0), Almost clear (1), mild (2), moderate (3), severe (4). An sPGA 0/1 response was defined as a post-baseline sPGA score of 0 or 1. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of subjects achieving PASI 75 response | Week 12 | The PASI75 response assessments are based on at least 75% improvement in PASI score from Baseline. |
| Proportion of subjects achieving PASI 100 response | Week 12 | The PASI100 response assessments are based on 100% improvement in PASI score from Baseline |
| PASI 90 response maintainance at week 48 | Week12-48 | Proportion of subjects maintaining PASI 90 response at Week 48 among those with PASI 90 response at Week 12 |
| sPGA 0/1 response maintainance at week 48 | Week12-48 | Proportion of subjects maintaining sPGA 0/1 response at Week 48 among those with sPGA 0/1 response at Week 12. |
