There existed no exclusion criteria. Information were most collected by a phone application called "Psoriasis New World". Primary outcome measure is the percentage of patients who achieved a PASI reduction of 100% (PASI 100). And Psoriasis Area and Severity Index includes scores of erythema, infiltration and desquamation, weighted by area of involvement in each regions (head and neck, upper extremities, trunk, lower extremities), with higher PASI scores indicating worse condition. Also, static Physician Global Assessment (sPGA), static Investigator Global Assessment (sIGA), Body surface area (BSA) and Dermatology Life Quality Index (DLQI) are measured to assess the severity of psoriasis and the change of the disease condition. It is important to monitor all the Adverse Events (AEs) over the whole study. In addition, the laboratory examinations of patients such as liver function are also collected.
