Clinical trials

Tezspire (tezepelumab-ekko) received FDA approval as an add-on maintenance treatment for individuals aged 12 years and older with severe asthma, based on data from the PATHFINDER clinical trial program. The program included the pivotal NAVIGATOR Phase III trial (NCT03347279), which involved randomly assigning adult and pediatric patients with severe, uncontrolled asthma who were receiving standard of care to receive Tezspire or placebo subcutaneously every four weeks for 52 weeks in a double-blinded, placebo-controlled trial.

NAVIGATOR’s primary efficacy outcome was the annualized rate of asthma exacerbations over 52 weeks. Secondary outcomes included Tezspire’s impact on lung function, asthma control, and health-related quality of life. Compared to placebo, patients receiving Tezspire exhibited a significant reduction in the annualized rate of asthma exacerbations, as well as improved lung function, asthma control, and quality of life.
