Brief summary
This was a randomized, double blind, placebo controlled, parallel group study in 129 subjects with moderate to severe psoriasis with a PASI score of at least 10. Following run-in, subjects were randomized and received either oral 30 mg ZPL-3893787 once daily or placebo once daily for 12 weeks.
Detailed description
This was a randomized, double blind, placebo controlled, parallel group study in 129 subjects with moderate to severe psoriasis with a Psoriasis Area and Severity Index (PASI) score of at least 10 and an Investigator's Global Assessment (IGA) of 3 (0-4 scale). Following run-in subjects received either oral 30 mg ZPL-3893787 once daily or placebo once daily for 12 weeks. Subjects attended the clinic at Baseline (Day 0) when they were reviewed and confirmed they met inclusion/exclusion criteria. Subjects were then randomized and received either oral 30 mg ZPL-3893787 once daily or placebo once daily for 12 weeks.

| Percent Change From Baseline in Psoriasis Assessment of Severity Index (PASI) at Week 12 | From baseline to week 12 | The PASI is an assessment routinely used for evaluating and grading the severity of psoriatic lesions and their response to therapy. PASI divides the body into 4 regions: the head, trunk, upper extremities (arms) and lower extremities (legs). Each of these areas is assessed separately for erythema, in duration and scaling; these symptoms are scored on a 5-point scale from 0-4, where 0 = no symptoms and 4 =very marked. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. A PASI 75 response represents a reduction of at least 75% from baseline in the PASI score. |
