Abrocitinib for moderate to severe atopic dermatitis

Abrocitinib is in development for the treatment of moderate to severe atopic dermatitis (AD) in adolescents and adults aged 12 years or over. AD is a chronic inflammatory skin disease that affects both children and adults and is characterised by redness, itchiness, and scaling of the skin. Some people only have small patches of dry skin, but others may experience widespread red, inflamed skin all over the body. Patients with moderate to severe AD could suffer from sleep disturbances, anxiety, depression, and poor quality of life. Currently, the management of AD involves the removal or treatment of trigger factors that contribute to the development of the disease.
Abrocitinib is a medicinal product taken by mouth (tablets) and acts by selectively blocking a protein called Janus Kinase 1 (JAK-1). JAKs contribute to cell processes that result in an immune or inflammatory response. JAK dependent enzymes are major contributors to the progression of immune-mediated diseases such as AD. Therefore, blocking these enzymes may be beneficial. Abrocitinib, if licensed, may offer the first oral, once-daily treatment option for patients with moderate to severe AD.
