Darzalex is an anti-CD38 monoclonal antibody and is used for the following:

Multiple myeloma:

• Given alone or in combination with certain other medications for people who haven’t responded well to previous treatments
• Given in combination with certain medications (other medications differ for people who can and can’t receive a stem-cell transplant)

Darzalex is an anti-CD38 monoclonal antibody. It treats multiple myeloma by targeting a specific protein called CD38 on the cells’ surface. Many cells, including healthy cells, have this protein. But multiple myeloma cells just have more of them. By binding to this protein, Darzalex attacks and kills the cancer cells, and also signals to the immune system to do the same. As a result, multiple myeloma cells can’t grow and spread as well.

• Darzalex is given as an infusion into the veins (IV) by a healthcare provider in a hospital or clinic setting. Your provider will determine your dose based on your body weight
• Adults: When Darzalex is given alone, the typical dose is 16 mg/kg once a week for 8 doses, then every 2 weeks for 8 doses, then every 4 weeks thereafter
• When Darzalex is given together with other anticancer medications, your provider will determine your dose and how often you receive it based on what medication combination you’re taking
