(Adds details in paragraph 2-4) Oct 17 (Reuters) - The U.S. Food and Drug Administration has approved Amgen and AstraZeneca's drug for a type of chronic sinus infection, the drugmakers said on Friday. The approval expands the use of the drug, Tezspire, as an add-on maintenance treatment of inadequately controlled chronic rhinosinusitis with nasal polyps in adult and pediatric patients aged 12 years and older. The condition causes the sinuses to stay inflamed for 12 weeks or more and soft, noncancerous growths called polyps to form in the nose. Symptoms include facial pain, reduced sense of smell and nasal congestion. Tezspire is already approved as a single-use pre-filled syringe in the U.S., EU and other countries for add-on maintenance treatment for severe asthma.
