Self-Care Tips

  • Ask your doctor before engaging in contact sports or activities that could cause injury.
  • Use an electric razor and a soft toothbrush to minimize bleeding. In general, drinking alcoholic beverages should be kept to a minimum or avoided completely. You should discuss this with your doctor.

Monitoring and Testing While Taking Caplacizumab-yhdp

You will be checked regularly by your doctor while you are taking Caplacizumab-yhdp, to monitor side effects and check your response to therapy. Periodic blood work will be obtained to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.

How Caplacizumab-yhdp Works

Caplacizumab-yhdp is classified as a monoclonal antibody. Monoclonal antibodies are a relatively new type of "targeted" cancer therapy.

Antibodies are an integral part of the body's immune system. Normally, the body creates antibodies in response to an antigen (such as a protein in a germ) that has entered the body. The antibodies attach to the antigen in order to mark if for destruction by the immune system.

To make monoclonal antibodies in the laboratory, scientists analyze specific antigens on the surface of cells (the targets). Then, using animal and human proteins, they create a specific antibody that will attach to the target antigen on the cell. When given to the patient, these monoclonal antibodies will attach to matching antigens like a key fits a lock. Since monoclonal antibodies target only specific cells, they may cause less toxicity to healthy cells.

Caplacizumab-yhdp works by targeting von Willebrand factor (vWF) which is a protein that is involved in the process of blood clotting. This blocks the interaction between von Willebrand factor and platelets, which decreases the formation of blood clotting.
