This study is looking at atopic dermatitis, a skin condition that causes areas of skin to become inflamed, itchy, red, cracked, and rough. The study will focus on people who have moderate to severe forms of this condition, meaning their symptoms are more than mild but can range to quite serious. The treatment being tested is lebrikizumab, which is also known by the code names RO5490255 and LY3650150. This medication is given as an injection under the skin using a pre-filled pen device. The purpose of the study is to confirm how well lebrikizumab works in improving the skin condition in people with moderate to severe atopic dermatitis.
During the study, participants will receive lebrikizumab treatment over a period of time, with the study lasting up to 24 weeks. The medication will be given at a dose of up to 500 milligrams per day, with a total amount of up to 3750 milligrams throughout the treatment period. The study will look at both areas of skin that show visible signs of the condition and areas that appear normal to see how the treatment affects the skin barrier, which is the protective outer layer of the skin that helps keep moisture in and harmful substances out.
The study will measure various aspects of the skin condition and how it responds to treatment. This includes looking at how much the overall severity of the skin condition improves, whether itching gets better, and how the condition affects quality of life. The study will also examine the skin in more detailed ways by measuring things like moisture levels, the natural protective substances in the skin, and other physical properties of the skin. Some measurements will involve taking samples from the skin surface using special tape, and in some adult participants, small skin samples may be taken. Blood tests will also be done to check vitamin D levels.
