Approved for use in Japan in patients with microscopic polyangiitis and granulomatosis with polyangiitis

SAN CARLOS, Calif., September 27, 2021 (GLOBE NEWSWIRE) – ChemoCentryx, Inc., (Nasdaq: CCXI), today announced that Kissei Pharmaceutical Co., Ltd. has received approval from the Japanese Ministry of Health, Labor, and Welfare (MHLW) to market TAVNEOS â„¢ (avacopan), a selective oral complement 5a receptor inhibitor, in Japan for the treatment of patients with Microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), the two main forms of anti-vasculitis associated with neutrophilic cytoplasmic autoantibodies also known as ANCA-associated vasculitis or ANCA vasculitis.

ChemoCentryx’s Kidney Health Alliance with Vifor Pharma grants Vifor Pharma exclusive rights to market avacopan in markets outside the United States, and Vifor Pharma has granted Kissei Pharmaceutical Co., Ltd. an exclusive license to market TAVNEOS â„¢ (avacopan), in Japan.

Vasculitis associated with ANCA has been officially designated as an incurable disease by MHLW. Incurable diseases are rare diseases for which no effective treatment exists but for which long-term treatment is necessary. Japan encourages research related to incurable diseases and financially supports patients with these diseases.

“This is the first-ever regulatory body approval of a new drug discovered and developed by ChemoCentryx. We would like to thank Kissei and the MHLW for their tremendous time and effort, which made possible this important milestone in the mission of bringing relief to patients with major unmet need, ”said Thomas J. Schall, Ph.D., President and CEO of ChemoCentryx.

In other countries, the PDUFA deadline for the Food and Drug Administration (FDA) decision on the Company’s amended NDA is October 7, 2021 and the regulatory decision in Europe following the review of the European Medicines Agency (EMA) is expected by the end of 2021..

On TAVNEOS â„¢ (avacopane)
TAVNEOS (avacopan), approved by the Japanese Ministry of Health, Labor and Welfare for the treatment of microscopic polyangiitis and granulomatosis with polyangiitis (the two main forms of vasculitis associated with ANCA), is a small medicine first class, administered orally. molecule that utilizes a novel, highly targeted mode of action in complement-induced autoimmune and inflammatory diseases. By precisely blocking the receptor (C5aR) of the fragment of the pro-inflammatory complement system known as C5a on destructive inflammatory cells such as blood neutrophils, avacopan stops the ability of these cells to damage in response to l activation of C5a, which is known to be the engine of vasculitis associated with ANCA. Current therapies for ANCA-associated vasculitis and other associated diseases generally include extensive immunosuppression with daily doses of glucocorticoids (steroids) such as prednisone or methylprednisone, which can cause significant illness and even death. Selective inhibition by TAVNEOS of C5aR alone leaves the beneficial C5a pathway via the normally functioning C5L2 receptor.

ChemoCentryx is also developing avacopan for the treatment of patients with C3 glomerulopathy (C3G), hidradenitis suppurativa (HS) and lupus nephritis (LN). The United States Food and Drug Administration has granted orphan drug designation avacopan for vasculitis associated with ANCA and C3G. The European Commission has granted orphan drug designation to avacopan for the treatment of two forms of vasculitis associated with ANCA: microscopic polyangiitis and granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis), as well as C3G.

About vasculitis associated with ANCAs
ANCA-associated vasculitis is a systemic disease in which overactivation of the complement pathway further activates neutrophils, leading to inflammation and destruction of small blood vessels. This leads to organ damage and failure, with the kidney being the primary target, and is fatal if left untreated. Currently, treatment of ANCA-associated vasculitis consists of courses of non-specific immunosuppressants (cyclophosphamide or rituximab), combined with daily administration of glucocorticoids (steroids) for prolonged periods, which may be associated with significant clinical risk. up to death. of infection.
