Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This Phase II study was designed as a multicenter, randomized, double-blind, placebo-controlled and 3-parallel arm, to assess clinical efficacy, safety, and tolerability of GN-037 versus clobetasol 17-propionate and placebo in patients diagnosed with mild to moderate plaque psoriasis at least 6 months ago

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of 190 patients aged between 18-65 years diagnosed with plaque psoriasis are planned to be included in the study. The study consists of three periods:

Screening period: Within 4 weeks before baseline visit (-28 days to 0 days)

Treatment period: 4 weeks

Follow-up period with observation: 4 weeks

The study is planned to last a maximum of 12 weeks for each patient. Study consists of 5 visits: baseline (day 1), week 2, week 4, week 6 and week 8 which is a follow-up period with observation.
