According to the data, a combo of Imfinzi (durvalumab) and chemotherapy significantly extended the lives of first-line patients with advanced biliary tract cancer over chemo alone.
The details are slim, but AstraZeneca said its combo achieved its overall survival and progression-free survival endpoints and a key overall response rate secondary endpoint.
The readout came from an interim analysis of the trial. It marked the first time an immuno-oncology regimen beat standard of care in a randomized trial for front-line biliary tract cancer.
This rare gastrointestinal cancer reports about 50,000 new diagnoses each year across the U.S., Europe, and Japan.
Price Action: AZN shares are up 0.39% at $62.01 during the premarket session on the last check Tuesday.
