This is a phase II study to evaluate the efficacy and safety of Icotinib Hydrochloride Cream in patients with mild to moderate psoriasis.
Icotinib Hydrochloride is an oral, small-molecule epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, which has been approved for treating advanced non-small cell lung cancer (NSCLC) in China. Over-expressions of EGFR and its downstream signaling proteins are implicated in the pathogenesis of psoriasis and TKIs have been considered as potential antipsoriatic agents. Icotinib hydrochloride is being developed as a cream for the treatment of mild to moderate psoriasis. This is a multicenter , randomized, doubleblind, four-arm parallel-group, placebo-controlled phase II study to assess the efficacy and safety of icotinib hydrochloride cream (1.0%, 2.0%, 4.0%) in patients with mild to moderate psoriasis. Approximately 260 subjects will be enrolled.

| Measure | Description | Time Frame |
|---|---|---|
| Percentage of participants achieving a 50% improvement from baseline in psoriasis area and severity index (PASI 50) score at week 8 | PASI: Combined assessment of lesion area and severity affected into single score. The body was divided into four sections [head (10% of a person's total skin); arms (20%); trunk (30%); legs (40%)]. For each section, the area of skin involved was scored from 0 (0%) to 6 (90-100%), and the severity of skin involved was estimated by clinical signs (erythema, induration, and desquamation) to score from 0 (none) to 4 (maximum). Final PASI = Sum of severity score for each section * area score * weight of section (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4). PASI 50 represents the percentage (or number) of patients who have achieved a 50% or more reduction in their PASI score from baseline. | 8 weeks |

| Percentage of participants achieving a 75% improvement from baseline in psoriasis area and severity index (PASI 75) score at each visit through week 12 | PASI: Combined assessment of lesion area and severity affected into single score. The body was divided into four sections [head (10% of a person's total skin); arms (20%); trunk (30%); legs (40%)]. For each section, the area of skin involved was scored from 0 (0%) to 6 (90-100%), and the severity of skin involved was estimated by clinical signs (erythema, induration, and desquamation) to score from 0 (none) to 4 (maximum).

| Percentage of participants achieving the physician global assessment (PGA) of psoriasis responses of clear (0) or almost clear (1) and ≥2 grade improvement at each visit through week 12 | PGA of Psoriasis: score based on dermatologist's assessment of skin disease averaged over all lesions. Overall lesions were graded for induration, erythema, and scaling; range: 0 (no evidence) to 5 (severe). Higher scores indicate greater severity of disease. | Baseline to week 12 |
| Lesion severity | Lesion severity includes the sum of 3 indications, e.g. Erythema, scaling, thickness of target psoriasis site on patients with mild to moderate psoriasis. Each indication is scored from 0 (not at all serious) to 4 (very serious). | Baseline to week 12 |
| Baseline to week 12 |
| Dermatology Life Quality Index (DLQI) | DLQI assessment includes 10 items, which encompass aspects such as symptoms and feelings, daily activities, leisure, work or school, personal relationships and side-effects of the treatment. Each item is scored from 0 (not at all relevant) to 1 (a little relevant), 2 (a lot relevant) and 3 (very much relevant).
