PRODUCT INTRODUCTION
description
Anti-neutrophil cytoplasmic (auto)antibody (ANCA)-associated vasculitis (AAV) is a rare (estimated incidence of 3 cases per 100,000 per year) form of "pauci-immune" systemic small-vessel vasculitis typified by the presence of ANCAs in the serum. The full spectrum of AAV includes granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), and drug-induced AAV. AAV may be associated with necrotizing and crescentic glomerulonephritis (NCGN). Despite complex pathophysiology, studies over the past ~2 decades have identified a key role for the alternative complement pathway and, in particular, the interaction between the anaphylatoxin fragment C5a and its cognate C5aR receptor in AAV. Avacopan (formerly CCX168) is an allosteric C5aR antagonist indicated for use in AAV. Avacopan was granted FDA approval on October 8, 2021, and is currently marketed under the name TAVNEOS by ChemoCentryx, Inc. On January 19, 2022, the European Commission approved avacopan for the treatment of adult patients with severe, active granulomatosis polyangiitis (GPA) or microscopic polyangiitis (MPA) - the two main forms of ANCA-associated vasculitis - in combination with [rituximab] or [cyclophosphamide]. Avacopan was approved by Health Canada on April 20, 2022.
