Uses for avelumab
Avelumab injection is used to treat metastatic Merkel cell carcinoma (skin cancer that has already spread).
Avelumab injection is also used to treat urothelial carcinoma, a type of bladder cancer, that has spread throughout the body (metastatic) or cannot be removed by surgery (advanced). Avelumab is given to patients who have received other cancer medicines (eg, platinum) that did not work well. It is also used as first-line maintenance treatment with urothelial carcinoma that has spread in patients who have responded well with platinum-containing cancer medicines.
Avelumab injection is also used together with other medicines (eg, axitinib) as first-line treatment of advanced renal cell carcinoma (RCC), a type of kidney cancer.
Avelumab belongs to the group of medicines called antineoplastics. It helps change the immune system to help control the growth of cancer cells.
Avelumab is to be given only by or under the direct supervision of your doctor.
