Avelumab Overview

Avelumab injection is used to treat Merkel cell carcinoma (MCC; a type of skin cancer) that has spread to other parts of the body in adults and children 12 years of age and older. Avelumab injection is also used to treat urothelial cancer (cancer of the lining of the bladder and other parts of the urinary tract) that has spread to nearby tissues or other parts of the body in people whose cancer worsened during or within 12 months after it was treated with platinum chemotherapy medications. It is also used as ongoing treatment for urothelial cancer that has spread to nearby tissues or other parts of the body to help maintain the response to platinum chemotherapy. Avelumab injection is also used in combination with axitinib (Inlyta) as a first treatment for renal cell carcinoma (RCC; cancer that begins in the kidney) that has spread or cannot be removed by surgery. Avelumab injection is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells.
