Avacopan, sold under the brand name Tavneos, is a medication used to treat anti-neutrophil cytoplasmic autoantibody-associated vasculitis. [5] [6] [8] Avacopan is a complement 5a receptor antagonist [5] and a cytochrome P450 3A4 inhibitor. [5]

Contents

The most common side effects include nausea (feeling sick), headache, decrease in white blood cell count, upper respiratory tract (nose and throat) infection, diarrhea, vomiting, and nasopharyngitis (inflammation of the nose and throat). [6]

Avacopan was approved for medical use in Japan in September 2021, [7] and in the United States in October 2021. [5] [8] [9] It is the first orally-administered inhibitor of the complement C5a receptor approved by the US Food and Drug Administration (FDA). [8] The FDA considers it to be a first-in-class medication. [10]

Medical uses

In the United States, avacopan is indicated as an adjunctive treatment of adults with severe active anti-neutrophil cytoplasmic autoantibody-associated vasculitis (granulomatosis with polyangiitis and microscopic polyangiitis) in combination with standard therapy including glucocorticoids. [5] [11]

In the European Union, avacopan, in combination with a rituximab or cyclophosphamide regimen, is indicated for the treatment of adults with severe, active granulomatosis with polyangiitis or microscopic polyangiitis. [6]

History

The FDA approved avacopan based on evidence from a clinical trial of 330 participants with severe active anti-neutrophil cytoplasmic autoantibody-associated vasculitis. [12] In the clinical trial, participants were randomly assigned to receive avacopan or placebo for 52 weeks. [12] Participants in the placebo group received a glucocorticoid taper over 20 weeks. [12] Neither the participants nor healthcare providers knew which medication was being given. [12] Participants in both groups received background immunosuppressive treatment (cyclophosphamide or rituximab) and were allowed to receive additional glucocorticoids. [12] The benefit of avacopan in comparison to placebo was assessed by proportion of participants who achieved remission at week 26 and sustained remission at week 52. [12] Data from this trial were also analyzed for the assessment of side effects. [12] The trial was conducted at 143 sites in 18 countries including the United States. [12] This trial assessed both efficacy and safety. [12] In the clinical trial, a greater proportion of participants who received avacopan for one year with other medicines (including glucocorticoids) achieved sustained disease remission compared to participants who received other medicines without avacopan. [12] The proportion of participants who achieved remission after six months of treatment was similar. [12]

Society and culture

In November 2021, the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Tavneos, intended, in combination with a rituximab or cyclophosphamide regimen, for the treatment of adults with severe, active granulomatosis with polyangiitis or microscopic polyangiitis. [13] The applicant for this medicinal product is Vifor Fresenius Medical Care Renal Pharma France. [13] The EMA considers avacopan to be a first-in-class medicine. [14] Avacopan was approved for medical use in the European Union in January 2022. [6] [15]

The FDA granted the application for avacopan orphan drug designation. [10]

Names

Avacopan is the international nonproprietary name. [16]

<span class="mw-page-title-main">Vasculitis</span> Medical disorders that destroy blood vessels by inflammation

Vasculitis is a group of disorders that destroy blood vessels by inflammation. Both arteries and veins are affected. Lymphangitis is sometimes considered a type of vasculitis. Vasculitis is primarily caused by leukocyte migration and resultant damage. Although both occur in vasculitis, inflammation of veins (phlebitis) or arteries (arteritis) on their own are separate entities.

<span class="mw-page-title-main">Granulomatosis with polyangiitis</span> Medical condition

Granulomatosis with polyangiitis (GPA), also known as Wegener's granulomatosis (WG), after the German physician Friedrich Wegener, is a rare long-term systemic disorder that involves the formation of granulomas and inflammation of blood vessels (vasculitis). It is an autoimmune disease and a form of vasculitis that affects small- and medium-size vessels in many organs but most commonly affects the upper respiratory tract, lungs and kidneys. The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels. Typical signs and symptoms include nosebleeds, stuffy nose and crustiness of nasal secretions, and inflammation of the uveal layer of the eye. Damage to the heart, lungs and kidneys can be fatal.

<span class="mw-page-title-main">Eosinophilic granulomatosis with polyangiitis</span> Medical condition

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as allergic granulomatosis, is an extremely rare autoimmune condition that causes inflammation of small and medium-sized blood vessels (vasculitis) in persons with a history of airway allergic hypersensitivity (atopy).

<span class="mw-page-title-main">Polyarteritis nodosa</span> Medical condition

Polyarteritis nodosa (PAN) is a systemic necrotizing inflammation of blood vessels (vasculitis) affecting medium-sized muscular arteries, typically involving the arteries of the kidneys and other internal organs but generally sparing the lungs' circulation. Small aneurysms are strung like the beads of a rosary, therefore making this "rosary sign" an important diagnostic feature of the vasculitis. PAN is sometimes associated with infection by the hepatitis B or hepatitis C virus. The condition may be present in infants.

Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, with glomerular crescent formation seen in at least 50% or 75% of glomeruli seen on kidney biopsies. If left untreated, it rapidly progresses into acute kidney failure and death within months. In 50% of cases, RPGN is associated with an underlying disease such as Goodpasture syndrome, systemic lupus erythematosus or granulomatosis with polyangiitis; the remaining cases are idiopathic. Regardless of the underlying cause, RPGN involves severe injury to the kidneys' glomeruli, with many of the glomeruli containing characteristic glomerular crescents.

<span class="mw-page-title-main">Phosphoinositide 3-kinase inhibitor</span>

Phosphoinositide 3-kinase inhibitors are a class of medical drugs that are mainly used to treat advanced cancers. They function by inhibiting one or more of the phosphoinositide 3-kinase (PI3K) enzymes, which are part of the PI3K/AKT/mTOR pathway. This signal pathway regulates cellular functions such as growth and survival. It is strictly regulated in healthy cells, but is always active in many cancer cells, allowing the cancer cells to better survive and multiply. PI3K inhibitors block the PI3K/AKT/mTOR pathway and thus slow down cancer growth. They are examples of a targeted therapy. While PI3K inhibitors are an effective treatment, they can have very severe side effects and are therefore only used if other treatments have failed or are not suitable.

<span class="mw-page-title-main">Ibrutinib</span> Medication used in cancer treatment

Ibrutinib, sold under the brand name Imbruvica among others, is a small molecule drug that inhibits B-cell proliferation and survival by irreversibly binding the protein Bruton's tyrosine kinase (BTK). Blocking BTK inhibits the B-cell receptor pathway, which is often aberrantly active in B cell cancers. Ibrutinib is therefore used to treat such cancers, including mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenström's macroglobulinemia. Ibrutinib also binds to C-terminal Src Kinases. These are off-target receptors for the BTK inhibitor. Ibrutinib binds to these receptors and inhibits the kinase from promoting cell differentiation and growth. This leads to many different side effects like left atrial enlargement and atrial fibrillation during the treatment of Chronic Lymphocytic Leukemia.

Vasculitic neuropathy is a peripheral neuropathic disease. In a vasculitic neuropathy there is damage to the vessels that supply blood to the nerves. It can be as part of a systemic problem or can exist as a single-organ issue only affecting the peripheral nervous system (PNS). It is diagnosed with the use of electrophysiological testing, blood tests, nerve biopsy and clinical examination. It is a serious medical condition that can cause prolonged morbidity and disability and generally requires treatment. Treatment depends on the type but it is mostly with corticosteroids or immunomodulating therapies.
