How does EMPAVELI work?

The complement cascade is a part of your immune system that protects your body from threats like viruses or bacteria. It is responsible for both kinds of hemolysis: intravascular and extravascular.

In the complement cascade, the C3 C3 A protein located in the blood
that acts as a central point of the
complement system, regulating
its activation. protein binds to your PNH red blood cells and tags them for destruction, activating C5 C5 A protein located in the blood
that plays an important role in
inflammation and intravascular
hemolysis caused by the
complement system. and causing intravascular hemolysis (IVH) intravascular hemolysis The destruction of red blood
cells inside a blood vessel. . PNH red blood cells that are not destroyed through IVH continue to be covered with C3 proteins, causing extravascular hemolysis (EVH) extravascular hemolysis The destruction of red blood cells
that occurs in the liver or spleen. .

EMPAVELI works higher in the complement system than other treatments, like eculizumab. It prevents C3 from splitting into C3a and C3b, helping to stop IVH and EVH. C5 treatments, like eculizumab, work on C5.
