The ADVOCATE trial of avacopan was a global randomized, double-blind, active-controlled, double-dummied Phase III trial of 331 patients with ANCA-associated vasculitis in 20 countries. Eligible study subjects were randomized to receive avacopan plus either rituximab or cyclophosphamide (followed by azathioprine/mycophenolate) or prednisone plus either rituximab or cyclophosphamide (followed by azathioprine/mycophenolate). The treatment period was 52 weeks.ANCA vasculitis is a systemic disease in which over-activation of the complement pathway further activates neutrophils, leading to inflammation and destruction of small blood vessels. This results in organ damage and failure, with the kidney as the major target, and is fatal if not treated. Currently treatment for ANCA vasculitis consists of courses of non-specific immuno-suppressants (cyclophosphamide or rituximab), combined with high-dose corticosteroid administration for prolonged periods of time, which can be associated with significant clinical risk including death from infection.About Avacopan
Avacopan is a first-in-class, orally-administered molecule that employs a novel, highly targeted mode of action in the treatment of ANCA-associated vasculitis and other complement-driven autoimmune and inflammatory diseases.  By precisely blocking the receptor (the C5aR) for the pro-inflammatory complement system fragment known as C5a on destructive inflammatory cells such as blood neutrophils, avacopan arrests the ability of those cells to do damage in response to C5a activation, which is known to be the driver of ANCA-associated vasculitis.  Current therapies for ANCA vasculitis and other related illnesses typically include broad immunosuppression with high doses of glucocorticoids (steroids) such as prednisone or methylprednisone, which cause significant illness and even death. Avacopan therapy was designed to prevent these outcomes. Moreover, avacopan’s selective inhibition of only the C5aR leaves the beneficial C5a pathway through the C5L2 receptor functioning normally.  ChemoCentryx is also developing avacopan for the treatment of patients with C3 glomerulopathy (C3G) and hidradenitis suppurativa (HS). The U.S. Food and Drug Administration has granted avacopan orphan-drug designation for ANCA-associated vasculitis and C3G. The European Commission has granted orphan medicinal product designation for avacopan for the treatment of two forms of ANCA-associated vasculitis: microscopic polyangiitis and granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis), as well as for C3G.ChemoCentryx’s Kidney Health Alliance with Vifor Pharma provides Vifor Pharma with exclusive rights to commercialize avacopan in markets outside of the U.S.About ChemoCentryx
ChemoCentryx is a biopharmaceutical company developing new medications targeted at inflammatory and autoimmune diseases and cancer. ChemoCentryx targets the chemokine and chemoattractant systems to discover, develop and commercialize orally-administered therapies. ChemoCentryx’s lead drug candidate, avacopan (CCX168), recently completed a pivotal Phase III trial in ANCA-associated vasculitis.ChemoCentryx also has early stage drug candidates that target chemoattractant receptors in other inflammatory and autoimmune diseases and in cancer.Forward-Looking Statements
