The double-blind, randomised, placebo-controlled, proof-of-concept trial is designed to assess the tolerability and safety of AX-158 versus placebo in patients with mild to moderate plaque psoriasis.

Subjects will be randomised into a 2:1 ratio to receive AX-158 or a placebo.

The trial will enrol 30 participants who will receive the treatment for 28 days and a subsequent dosing for another additional 30 days.
