About

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

Full 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.
