About Atopic Dermatitis and Chronic Pruritus
Atopic dermatitis is a chronic, relapsing inflammatory skin disorder characterized by the symptom of intense and persistent pruritus or itch. Other clinical features include erythema, excoriation, edema, lichenification, oozing and xerosis.
Atopic dermatitis is a common skin disorder affecting millions of people worldwide. Currently there are very few safe systemic treatments available for atopic dermatitis, representing a significant unmet medical need in this population.
About the Neurokinin-1 Receptor and Substance P
The Neurokinin-1 Receptor (NK-1R) is expressed throughout different tissues of the body, with major activity found in neuronal tissue. Substance P (SP) and NK-1R interactions in neuronal tissue regulate neurogenic inflammation locally and the pain perception pathway through the central nervous system. Other tissues, including endothelial cells and immune cells, have also exhibited SP and NK-1R activity (2). The activation of NK-1R by the natural ligand SP is involved in numerous physiological processes, including the perception of pain, behavioral stressors, cravings and the processes of nausea and vomiting (1,2,3). An inappropriate over-expression of SP, either in nervous tissue or peripherally, could result in pathological conditions such as substance dependence, anxiety, nausea/vomiting and pruritus (1,2,3,4). An NK-1R antagonist may possess the ability to reduce this over-stimulation of the NK-1R, and as a result address the underlying pathophysiology of the symptoms in these conditions.
Tradipitant is an NK-1R antagonist licensed by Vanda from Eli Lilly and Company (Lilly) in 2012. Tradipitant is currently in clinical development for atopic dermatitis and gastroparesis. The patent describing tradipitant as a new chemical entity is expected to expire in the United States in June 2029 based on an anticipated Hatch-Waxman patent term extension. Tradipitant is an investigational drug that is not currently approved for use in any indication.
