The U.S. Food and Drug Administration has granted breakthrough therapy designation to AstraZeneca's biggest new drug hope durvalumab as a treatment in bladder cancer, the drugmaker said on Wednesday.
The experimental medicine is a so-called PD-L1 therapy that fights cancer by boosting the immune system.
Breakthrough therapy designation expedites the development and review of medicines intended to treat serious or life-threatening diseases.
