Testing A New Combination of Anti-cancer Immune Therapies, Atezolizumab and CDX-1127 (Varlilumab) With or Without the Addition of a Third Anti-cancer Drug, Cobimetinib, for Advanced-Stage Biliary Tract Cancer (NCT04941287)
A Randomized Phase 2 Study of Combination Atezolizumab and CDX-1127 (Varlilumab) With or Without Addition of Cobimetinib in Previously Treated Unresectable Biliary Tract Cancers
🩺 Plain-English Summary (8th-Grade Level)
This phase II trial investigates the effect of combining two immune therapies, atezolizumab and CDX-1127 (varlilumab), with or without cobimetinib, in treating patients with biliary tract cancer that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Varlilumab is an immune agonist antibody that may further strengthen the immune system's attack on the cancer. Cobimetinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab in combination with varlilumab and cobimetinib may work better than atezolizumab and varlilumab alone in treating patients with unresectable biliary tract cancer.
