What is Tavneos?
Tavneos (avacopan) capsules are used to treat granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) to help reduce inflammation and improve symptoms. Tavneos works by blocking a different disease pathway and is an add-on to standard therapy for adults with active and severe symptoms. Granulomatosis with polyangiitis and microscopic polyangiitis are two forms of ANCA-associated vasculitis.
Tavneos works by blocking a receptor in the blood called complement 5a (or C5a), which is part of the immune system. When Tavneos blocks the C5a receptor it may help reduce blood vessel inflammation, improving disease symptoms. It is called a complement 5a receptor (C5aR) antagonist.
Tavneos FDA approval is for severe active ANCA-associated vasculitis (granulomatosis with polyangiitis and microscopic polyangiitis) in adults when used together with standard therapy, including glucocorticoids. Tavneos is manufactured by Chemocentryx, which has been acquired by Amgen.
What is ANCA-associated vasculitis?
Anti-neutrophil cytoplasmic autoantibody-associated vasculitis (ANCA-associated vasculitis) is a rare autoimmune disease that causes inflammation and damage to small or medium-sized blood vessels, affecting various organs, including airways, kidneys, and lungs. Two forms of ANCA-associated vasculitis are granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA)
Granulomatosis with polyangiitis (GPA) mainly affects the respiratory tract and the kidneys, leading to sinusitis, nosebleeds, and kidney disease. Granulomatosis with polyangiitis was previously called Wegener’s granulomatosis. Tavneos is used to treat granulomatosis with polyangiitis.
Microscopic polyangiitis (MPA) mainly affects the kidneys and lungs and, compared to GPA, less often involves the upper respiratory tract. Tavneos is used to treat microscopic polyangiitis.
