This clinical trial is focused on studying treatments for patients with a type of cancer called gastric cancer or gastroesophageal junction cancer. These are cancers that occur in the stomach or where the stomach meets the esophagus. The study will explore the effects of a medication called Durvalumab, which is given as an infusion, meaning it is delivered directly into the bloodstream through a vein. Durvalumab is being tested in combination with a chemotherapy regimen known as FLOT, which includes the drugs Fluorouracil, Leucovorin (also known as Folinic Acid), Oxaliplatin, and Docetaxel. These drugs are used to kill cancer cells or stop them from growing. The study will also involve a placebo, which is a substance with no active medication, to compare the effects of the treatment.
The purpose of this study is to see if the combination of Durvalumab and FLOT chemotherapy, followed by additional Durvalumab treatment, can improve outcomes for patients with resectable gastric or gastroesophageal junction cancer. “Resectable” means that the cancer can be surgically removed. The study will be conducted in phases, starting with treatment before surgery (neoadjuvant) and continuing after surgery (adjuvant). Participants will be randomly assigned to receive either the active treatment or a placebo, and neither the participants nor the researchers will know who is receiving which treatment until the study is completed. This is known as a double-blind study.
The study will last for a period of up to 18 months, during which participants will receive the treatments and be monitored for their health and response to the treatment. The main goal is to assess event-free survival, which means the length of time participants live without the cancer getting worse or coming back. Secondary goals include overall survival and the rate of complete response to the treatment. This study aims to provide valuable information on the effectiveness of Durvalumab in combination with FLOT chemotherapy for treating gastric and gastroesophageal junction cancers.
