Study on Atopic Dermatitis

This research is to test new treatments for people with atopic dermatitis (AD), which is a skin condition causing itchy and inflamed skin. The study will compare different treatments to a placebo (a substance with no active medication) to see which works best. Participants will be randomly placed into groups and neither they nor the researchers will know who gets the real treatment or the placebo. This is called a double-blind study. The first treatment being tested is called GHZ339. The study is in Phase II, which means it is in an early stage where researchers check if the treatment is safe and effective.

• The study requires several visits to the research center.
• Participants need to have had AD for at least a year and it should be moderate to severe.
• People with certain medical conditions, like serious infections or uncontrolled diseases, cannot join.
