Generic Name: daratumumab (DAR a TOOM ue mab)
Brand Name: Darzalex
What is daratumumab?
Daratumumab is a monoclonal antibody that blocks a certain protein in the body that can affect tumor cell growth. Monoclonal antibodies are made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
Daratumumab is used to treat multiple myeloma (bone marrow cancer). Daratumumab is usually given after other cancer medicines have been tried without success.
Daratumumab is used alone when given to a person who has been treated with at least 3 prior cancer medicines.
For a person treated with only 1 prior cancer medicine, daratumumab may be given in combination with another cancer medicine (either lenalidomide or bortezomib) plus a steroid medicine called dexamethasone.
Daratumumab was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, patients with multiple myeloma responded to this medicine. However, further studies are needed.
Daratumumab may also be used for purposes not listed in this medication guide.
