Official Title ICMJE | A Randomized, Placebo-controlled, Double-blind, Parallel-group, Multicenter Phase 2a Study to Investigate Efficacy and Safety of Zabedosertib (BAY 1834845) for the Treatment of Adult Patients With Moderate-to-severe Atopic Dermatitis | ||||
Brief Summary | Researchers are looking for a better way to treat atopic dermatitis (AD), an often long-lasting inflammation of the skin. Atopic dermatitis, also called eczema, is causing patches of skin to become swollen, red, cracked, and itchy. The immune system helps protect the body from diseases. But sometimes the immune system can be too sensitive and overreact. This may then lead to allergies but also to skin conditions like atopic dermatitis. The study treatment zabedosertib (BAY1834845) is currently under development for the treatment of atopic dermatitis and other inflammatory diseases. It works by reducing the activity of a protein called IRAK4. IRAK4 promotes the production and activation of a series of proteins that trigger inflammation reactions in the immune cells. By reducing the activity of IRAK4, the inflammation reactions are expected to be reduced. The main purpose of the study is to learn how well zabedosertib works compared to placebo. A placebo is a treatment that looks like a medicine but does not have any medicine in it. How well it works means to find out the efficacy of zabedosertib. To answer this, the researchers will compare how many participants had 75% EASI score reduction after 12 weeks treatment between participants treated with zabedosertib and those treated with placebo. EASI represents Eczema Area and Severity Index (EASI). It is a tool for measuring the amount and severity of atopic dermatitis that a patient has on his or her body. The score ranges from 0-72, with 0 meaning clear skin and 72 meaning severe atopic dermatitis. In addition, the itch of the study participants and other tools for measuring the severity of atopic dermatitis will be assessed. The secondary purpose of the study is to learn how safe it is compared to placebo. To know this, study team will compare how many participants having adverse events after taking study treatment between participants treated with zabedosertib and those treated with placebo. In the study, participants will be randomly (by chance) assigned to receive zabedosertib or placebo. The participants from both treatment groups will take zabedosertib or placebo for up to 12 weeks. The study consists of an up to 28-day screening period (Visits 1 and 2), a 12-week treatment period consisting of 5 visits (Visits 3 to 7), and a 4-week follow-up visits (Visits 8). Thus, the total study duration per participant will be 17 to 20 weeks (approximately 140 days). During the study, the study team will:
An adverse event is any problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. At 28 days after the participants take their last treatment, the study team will check if participants have any events that might be related to the study treatment. This will be the last visit for the study. |
