Clinical Trial Summary

This is a phase II study to evaluate the efficacy and safety of Icotinib Hydrochloride Cream in patients with mild to moderate psoriasis.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Safety in patients with mild to moderate psoriasis: Incidence and severity of Adverse Events, Physical Examinations, Vital signs, clinical laboratory assessments, ECG	Incidence and severity of Adverse Events, Physical Examinations, Vital signs (temperature, Heart Rate, blood pressure and respiration rate), clinical laboratory assessments (serum chemistry, hematology, C-reactive protein, fecal and urinalysis), ECG, etc.	Baseline to week 12
Other	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). The scores of items 1-10 for change from baseline are summarized here.	Baseline to week 12
Primary	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
Secondary	PASI 50 score at each visit through week 12 (except 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.	Baseline to week 12 (except week 8)
Secondary	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). 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 75 represents the percentage (or number) of patients who have achieved a 75% or more reduction in their PASI score from baseline.	Baseline to week 12
Secondary	Change PASI score at each visit from baseline 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). 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).	Baseline to week 12
Secondary	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
Secondary	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
