Study: NCT04563338

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Atezolizumab
Description: Atezolizumab is a type of drug called a monoclonal antibody. Antibodies are proteins that are naturally found in the blood stream that fight infections. Monoclonal antibodies are a special kind of antibody that is created in a laboratory. These drugs bind (attaches) to specific proteins in the body that may be involved in cancers. Atezolizumab binds to PD-L1 which is a protein involved preventing the body's immune system (defense system against infection and disease) from fighting cancer cells. Blocking PD-L1 is expected to help the immune cells to destroy the cancer cells.

Intervention: Bevacizumab
Description: Bevacizumab is a type of drug called a monoclonal antibody. Antibodies are proteins that are naturally found in the blood stream that fight infections. Monoclonal antibodies are a special kind of antibody that is created in a laboratory. These drugs bind (attaches) to specific proteins in the body that may be involved in cancers. Bevacizumab binds to vascular endothelial growth factor (VEGF) which is a protein involved with the growth of new blood vessels. Blocking VEGF will prevent blood vessels from forming and therefore stopping oxygen and nutrients to be supplied to cancer cells. Without oxygen and nutrients, the cancer cells will die.
