Hepatobiliary Neoplasm clinical trials

Combination of Targeted and Immunotherapy for Advanced Biliary Tract and Esophagogastric Gastric Cancer

In this study, non-operable esophagogastric adenocarcinoma cancer patients or non-operable biliary cancer patients whose cancer progressed/spread/got worse after first line treatment will be treated with or without immunotherapy and chemotherapy. This study will take place in several countries across Europe. One hundred twenty-three (123) patients will be invited to participate in this study Biliary tract cancer (BTC), is a form of cancer that start in your bile ducts, a series of tubes that runs from the liver to the small intestines. It is not know yet the exact cause of BTC. For patients who have advanced or metastatic BTC (where surgery is not possible), chemotherapy is the first option for treatment. Chemotherapy with cisplatin and gemcitabine (CisGem) is the current standard of care. Esophagogastric cancer (EGC) is cancer that occurs in the esophagus, a long hollow tube that runs from your throat to your stomach. The accumulating abnormal cells form a tumor in the esophagus that can grow to invade nearby structures and spread to other parts of the body. It's thought that chronic irritation of your esophagus may contribute to the changes that cause esophageal cancer. The purpose of this study is to look at the risks and benefits of combining DKN-01 and atezolizumab (humanized monoclonal antibody) with or without paclitaxel (chemotherapy). Immune therapy boosts the body's natural defenses to fight cancer. It uses specific products made either by participants' body or in a laboratory to improve, target or restore immune system function and control or stop cancer. Atezolizumab is such an "immunotherapy" drug. DKN-01 is another new type of drug (humanized monoclonal antibody) in development as anticancer agent. Paclitaxel is a commonly-used chemotherapy drug of the class of taxanes used to treat a number of cancer types, it stimulates the cell to die or to stop the cell from dividing into two new cells.The idea behind combining these drugs is linked to targeting the immune system to attack the tumor. Combining immune and chemotherapy has already demonstrated clinical activity in relapsed (return of the disease)/refractory (not responding to treatment) esophagogastric cancer patients.
