What is Danyelza?
Danyelza is a prescription medicine used to treat high-risk neuroblastoma (a rare form of cancer) in adults and children at least 1 year old.
Danyelza is used in combination with another medicine called granulocyte-macrophage colony-stimulating factor (GM-CSF) that causes your body to produce certain blood cells that help fight the cancer and protect you from infection.
Danyelza is given after other cancer treatments did not work well, or have stopped working.
Danyelza was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, some people responded to this medicine, but further studies are needed.
Danyelza can cause serious side effects. Call your doctor at once if you have pain or a severe headache, numbness or tingling, weakness, problems with speech or thought, vision problems, painful urination, fast or pounding heartbeats, chest pain, or a seizure.
Tell your caregiver if you have any of these side effects during the injection: feeling dizzy or light-headed, itching, warmth or tingling, shortness of breath, noisy breathing, or swelling in your face.
