EFFECTS OF TRALOKINUMAB ON THE SKIN: AN IMMUNOLOGICAL AND MOLECULAR STUDY
Summary description of the study
Tralokinumab is a new medication for the treatment of atopic dermatitis. It is used for moderate to severe atopic dermatitis. It is injected under the skin every two weeks. In Switzerland, it has been approved for the treatment of atopic dermatitis since February 2022. In large studies involving over 1500 patients, it has already been shown that Tralokinumab is effective against atopic dermatitis and well tolerated. However, little is known about where exactly in the skin the medication acts. This may be important to know which patients can particularly benefit from the treatment. Additionally, it could help to better understand the disease itself. Therefore, we want to investigate how much of the medication can be detected in the skin. Furthermore, we want to know what changes occur in the skin under the treatment. We will examine both skin cells and certain signaling substances in the skin and blood. Study participants will receive Tralokinumab for 16 weeks. After four and 16 weeks, we will assess how well the atopic dermatitis has responded to the treatment. Additionally, blood and skin samples will be taken. For control, we also want to include 5 healthy subjects. For these, only the skin will be examined and skin and blood samples will be taken. The control subjects will not receive any medication.
