What is Tavneos?
Tavneos is a prescription medicine that is used with other medicines (such as glucocorticoids) to treat adults with severe active anti-neutrophil cytoplasmic autoantibody (ANCA)- associated vasculitis (granulomatosis with polyangiitis [GPA], formerly known as Wegener’s granulomatosis, and microscopic polyangiitis [MPA]).
It is not known if Tavneos is safe and effective in children under the age of 18.
TAVNEOS (avacopan) capsules contain avacopan, a C5aR antagonist. Avacopan is a chiral molecule containing two stereocenters and has a chemical name of (2R,3S)-2-[4-(cyclopentylamino)phenyl]-1-(2-fluoro-6-methylbenzoyl)-N-[4-methyl-3-(trifluoromethyl)phenyl]piperidine-3-carboxamide. It has a molecular formula of C33H35F4N3O2 and a molecular weight of 582 g/mol. Avacopan has the following structural formula:
Avacopan is a white to pale yellow crystalline solid that is soluble in organic solvents and practically insoluble in water.
TAVNEOS is available as a 10 mg capsule for oral administration. The capsules include the following inactive ingredients: Polyethylene glycol 4000 (PEG-4000), Polyoxyl-40 hydrogenated castor oil. The capsules are a light orange and yellow opaque bicolor gelatin capsule with a clear gelatin sealing band. The top half of the capsule is printed with “CCX168” in black ink. The capsule shell contains gelatin, red iron oxide, yellow iron oxide, and titanium dioxide, and the capsule sealing band contains gelatin and polysorbate 80.
Mechanism of Action
Avacopan is a complement 5a receptor (C5aR) antagonist that inhibits the interaction between C5aR and the anaphylatoxin C5a. Avacopan blocks C5a-mediated neutrophil activation and migration. The precise mechanism by which avacopan exerts a therapeutic effect in patients with ANCA-associated vasculitis has not been definitively established.
