Summary
Brief summary
The primary objective is to evaluate the safety and tolerability of subcutaneous injections of ART621 given every 2 weeks for 6 doses as assessed by adverse events and clinical laboratory data. Assessments of efficacy will include the Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA), photographs and the Dermatology Life Quality Index (DLQI).

Each subject will be on-study for 18-20 weeks, consisting of a 2-4 week screening period, followed by a 12 week treatment period and then a 4 week follow up. Each subject will receive their designated dose of ART621 on 6 occasions over the 12 week treatment period and will be monitored closely throughout.
