Roflumilast: Promising Candidate for Asthma, COPD


Clinical trials show that an investigational phosphodiesterase 4 (PDE4) inhibitor improves symptoms in two important groups: those with asthma and patients with chronic obstructive pulmonary disorder (COPD). If approved for marketing, roflumilast (Daxas) would be an important new product for the German developer, Altana Pharma. However, an agreement to codevelop Daxas with Pfizer was terminated on July 1, creating some uncertainty as to how far Altana will take the product in the United States as well as other parts of the world.
