About the Complement Factor D Platform

Achillion has leveraged its internal discovery capabilities and a novel complement-related drug development platform to develop small molecule factor D inhibitor compounds that target the complement Alternative Pathway (AP). Factor D is an essential serine protease involved in the AP, a part of the innate immune system. Achillion's complement platform is focused on seeking to advance small molecule compounds that inhibit factor D and can potentially be used in the treatment of immune-related diseases in which the AP plays a critical role. Potential indications currently being evaluated for these compounds include C3G, immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN), and paroxysmal nocturnal hemoglobinuria (PNH).

About C3G

C3G is a devastating disease affecting the kidneys for which there is no FDA approved therapy. C3G affects men and women equally. There are estimated to be approximately 4,000 C3G patients in the United States, more than 4,000 in Europe, and more than 1,000 patients with this disease in Japan. C3G is a rare renal disease characterized by the presence of predominantly C3 protein fragments in the filtering units (glomeruli) of the kidney. These C3 fragment deposits are thought by experts to be the result of overactivation of the complement alternative pathway (AP). The chronic deposition of C3 fragments results in inflammation in the glomeruli (glomerulonephritis) and subsequent permanent renal damage. An estimated 30-50% of C3G patients will require dialysis or a transplant within 10 years of diagnosis.
