With AD there is a need to target different immune activities to achieve 100% clearance in all patients. Research into the immune mediators of AD opened doors to tremendous scientific development. Emma Guttman-Yassky, chair of dermatology and immunology at the Icahn School of Medicine at Mount Sinai in New York said, “This is a very exciting time for biologics in AD. “This could lead to prolonged remission times even after the drug is stopped, which is very exciting!”Ī biologics revolution for AD treatment is on the wayĭr. Eric Simpson of Oregon Health and Science University, and chair of NEA’s Research Advisory Committee, one of the clinical researchers working to take biologics for AD through clinical trials. “Some biologics in early development can actually kill some of the inflammatory cells rather than making them quiet,” according to Dr. Currently, biologic mAb need to be injected in order to be effective, since taking them through the digestive system would disrupt their three-dimensional protein structure and render them unable to bind to their targets - much like a key needs to be a certain configuration to open a lock. These mAb work similar to antibodies made by the body during an immune response to a virus or a bacteria, but instead of targeting the microbe, they can target specific immune cells or proteins in the body, bind to them tightly and prevent them from exerting their effects or even get rid of them. Biologics for diseases like psoriasis and asthma have been available since 2003 and provided clues about how a similar approach for AD could be possible.Ī biologic, such as dupilumab, is made in a laboratory by cells that produce human monoclonal antibodies (mAb), a protein made up of amino acids. Biologics for a number of immune-mediated diseases have offered a revolutionary way to more directly target key immune response pathways involved in disease, while leaving other immune responses unaffected. Dupilumab is also considered a systemic agent, in that it acts on the whole body, but due to its ability to target only a specific component of the immune response (the IL-4 receptor alpha), it is not immunosuppressive and has offered a much needed new approach for the treatment of moderate-severe AD. Traditional ‘whole-body’ systemic medications for AD include broadly immunosuppressive agents such as cyclosporine and methotrexate. ‘whole-body’) types of medications to better control their AD and improve quality of life. Others have more severe disease that is resistant to topical treatments and need systemic (i.e. Some people with AD can be treated with medications applied to the surface of the skin (topical medications) to ‘turn down’ inflammatory immune responses and control itch. In AD, new biologic drugs can modify the elevated immune response driving the disease. Biologic drugs are sometimes called “biologic response modifiers” because they change a process already occurring in cells or for a particular disease. Now, several additional cytokines and ILs are also thought to play a role in AD - meaning more potential options for future biologic therapies.īiologics: What are they and how can they improve treatment of eczema?Ī biologic is a drug made from biological (living) sources like cells from humans, animals, plants, fungi or microbes. The biologic dupilumab works to inhibit the activity of two key ILs in AD, IL-4 and IL-13. Cells of the immune system, called T cells, secrete messengers called cytokines and interleukins (IL) that tell other immune cells to get involved, leading to inflammation, signal structural cells of the skin (keratinocytes) to break down the skin barrier and even cause itch ( Figure 1). ![]() Years of dedicated scientific studies have teased out important clues about specific immune responses that contribute to AD and its symptoms. ![]() The bacteria that call the skin home (such as Staphylococcus aureus) can also play a role in AD. AD is caused by both an “elevated” immune response within the skin and a defective skin barrier which can have underlying genetic or environmental factors (like allergens). ![]()
