Stereotactic Body Radiation Therapy (SBRT) Combined With Avelumab (Anti-PD-L1) for Management of Early Stage Non-Small Cell Lung Cancer (NSCLC)

The purpose of the study is to determine whether avelumab has an effect on cancer and body in combination with SBRT, a standard treatment for early stage non-small cell lung cancer (NSCLC).

Avelumab is considered experimental because it is not approved by the United States (U.S.) Food and Drug Administration (FDA) for the treatment of cancer. It is a type of drug called a monoclonal antibody (a type of protein). Monoclonal antibodies are made to recognize, target and bind to specific proteins on the cells that make up your tissues. Avelumab is designed to block the interaction between PD-1, a known immune checkpoint, and PD-L1. By blocking this interaction, the immune system may be stimulated, allowing it to more effectively recognize and attack the cancer.

Stereotactic Body Radiation Therapy (SBRT) is a type of radiation that uses precise targeting to deliver a high dose of radiation to the tumor over a short period of time. A positioning cushion such as Vac-lok will be used during radiation treatment that is custom made. This custom mold forms to the contours of the subjects body to allow for proper positioning comfort and stability.
