- Pharmaceutical giant Astrazeneca said a late-stage trial of its antibody plus chemotherapy to treat advanced biliary tract cancer met its primary goal.

The independent data monitoring committee concluded that the trial met the primary endpoint by 'demonstrating an improvement in overall survival in patients treated with Imfinzi plus chemotherapy versus chemotherapy alone,' the company said.

'The combination also demonstrated an improvement in progression-free survival and overall response rate, key secondary endpoints,' it added.

Biliary tract cancer is a group of rare and aggressive cancers that occur in the bile ducts and gallbladder.
