Monitoring and Testing:

You will be checked regularly by your health care professional while you are taking eculizumab, to monitor side effects and check your response to therapy. Periodic blood work 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 Soliris Works:

Soliris is classified as a monoclonal antibody.  Monoclonal antibodies are a relatively new type of "targeted" cancer or biologic 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 it for destruction by the immune system.

In the laboratory, scientists analyze specific antigens on the surface of cancer cells (target) to determine a protein to match the antigen. Then, using protein from animals and humans, scientists work to create a special antibody that will attach to the target antigen. An antibody will attach to a matching antigen like a key fits a lock. This technology allows treatment to target specific cells, causing less toxicity to healthy cells. Monoclonal antibody therapy can be done only for cancers or diseases in which antigens (and the respective antibodies) have been identified.

Soliris is a targeted therapy that targets and binds to the complement protein C5, this in turn prevents the splitting of this protein interfering with the formation of membrane attack complex (MAC).  This interference prevents the destruction of red blood cells (hemolysis) and therefore results in stabilization of hemoglobin and a decrease in the need for blood transfusions in persons with paroxysmal nocturnal hemoglobinuria (PNH).
