NeRRe Therapeutics is developing orvepitant, a neurokinin (NK)-1 receptor antagonist, as a first in class, once daily breakthrough treatment for cough hypersensitivity disorders. Having demonstrated proof of efficacy in patients with refractory or unexplained cough, NeRRe will now continue development in chronic cough caused by the rare and terminal lung disease idiopathic pulmonary fibrosis (IPF). A dominant feature of this severe progressive respiratory disease in a high proportion of patients is an uncontrolled and persistent cough which is disabling for these terminally ill patients. The cough is often refractory to medical therapy and there are no approved treatments. Idiopathic pulmonary fibrosis has been designated an orphan disease in both Europe and the USA.
