A New Therapy Offers A Different Approach to Inhibiting the Complement System

Earlier the month the U.S. Food and Drug Administration approved Apellis Pharmaceuticals Empaveli to treat paroxysmal nocturnal hemoglobinuria (PNH), a rare and life-threatening condition in which the body’s immune system destroys the oxygen carrying red blood cells. Like existing treatments Soliris and Ultomiris, Empaveli works to inhibit the complement system, but it is the first therapy to target the portion of this immune cascade known as C3. We spoke to Cedric Francois, co-founder and CEO of Apellis, about Empaveli, what advantages it may provide over existing therapies for PNH, and other indications the company will pursue for this medicine.
