DBV Technologies is a clinical-stage specialty biopharmaceutical company focused on immunotherapy. Co.'s therapeutic approach is based on epicutaneous immunotherapy (EPIT), its proprietary method of delivering biologically active compounds to immune systems through intact skin using a platform called Viaskin. Viaskin is an electrostatic patch that offers a self-administered, non-invasive immunotherapy to patients. Once applied on intact skin, Viaskin forms a condensation chamber that hydrates the skin and solubilizes the antigen, allowing it to penetrate the epidermis, where it's captured by Langerhans cells. Co.'s patients include infants and children suffering from severe food allergies.
