E.5 End points |
E.5.1 | Primary end point(s) |
- Descriptive analysis of blood and skin inflammatory biomarkers (YES [presence of inflammatory biomarkers]/NO [no presence of inflammatory biomarkers]) at each visit - Proportion of patients with psoriasis relapse during the 96-week follow-up period (YES [relapse]/ NO [disease control]), where relapse is defined using the following thresholds: ● PASI >3* (in patients who had a PASI ≤3 at baseline) ● PASI >5* (in patients who had a PASI ≤5 at baseline) ● DLQI >5* (in patients who had a DLQI ≤5 at baseline) ● Initiation of any topical drug/medication for psoriasis†^ ● Initiation of any systemic therapy for psoriasis (biologic or non-biologic)† *Only to be considered at first occurrence †To be considered at every occurrence ^Only apply to topical drugs/medications (not soaps, shampoos, emollients, keratolytics, etc, will be included in this group) |
