AstraZeneca's Imfinzi delays bladder cancer return in high-risk patients

  • AstraZeneca PLC (LSE:AZN) has reported encouraging results from a late-stage trial of its cancer immunotherapy Imfinzi, which significantly extended the time patients with early-stage bladder cancer lived without their disease coming back or getting worse. The data, released Friday, come from the company's phase III POTOMAC trial and mark a potential breakthrough for patients with high-risk non-muscle-invasive bladder cancer, a form of the disease that accounts for the majority of bladder cancer diagnoses and has a stubborn tendency to return.
