This clinical trial is focused on studying a type of cancer known as biliary tract carcinoma, which affects the bile ducts and gallbladder. The study is investigating the effectiveness of two treatments: a combination of capecitabine and durvalumab (also known by its code name MEDI4736), and capecitabine alone. Capecitabine is a medication that comes in the form of film-coated tablets, while durvalumab is given as a concentrate for solution for infusion, which means it is administered through a drip into a vein.
The purpose of the study is to evaluate how well these treatments work in preventing the return of cancer in patients who have had their biliary tract carcinoma surgically removed. The study will follow participants over a period of time to see if the cancer comes back and to assess their overall health and quality of life. Participants will be randomly assigned to receive either the combination of capecitabine and durvalumab or capecitabine alone. Some participants may receive a placebo, which is a substance with no active medication, to help compare the effects of the treatments.
The study will last for several months, with regular visits to monitor the participants’ health and response to the treatment. The main goal is to see if the combination of capecitabine and durvalumab can improve the time patients remain free from cancer compared to capecitabine alone. The study will also look at the safety of the treatments and how they affect the participants’ quality of life. This research aims to provide valuable information that could help improve treatment options for patients with biliary tract carcinoma in the future.
