Tezepelumab cuts oral steroid dependence in severe asthma
In the phase 3b WAYFINDER trial (NCT05274815), 298 adults with severe, oral corticosteroid (OCS)-dependent asthma received tezepelumab 210 mg SC every 4 weeks for 52 weeks, following a 4-week stable baseline dosing. By week 52, ~90% reduced their prednisone to ≤5 mg/day, and 50.3% fully discontinued OCS without loss of asthma control. Benefits were consistent across pre-specified subgroups based on baseline eosinophil count, fractional exhaled nitric oxide level, and allergy status. Serious adverse events occurred in 9.4%, with 1.3% discontinuing treatment.
