ChemoCentryx, Inc., (Nasdaq: CCXI), today announced that, following consultations with the U.S. Food and Drug Administration (FDA), it filed an amendment to its New Drug Application (NDA) for avacopan for the treatment of Anti-neutrophil Cytoplasmic Autoantibody (ANCA)-associated vasculitis, addressing points raised during the FDA Advisory Committee meeting on May 6, 2021
SAN CARLOS, Calif., July 06, 2021 (GLOBE NEWSWIRE) -- ChemoCentryx, Inc. (Nasdaq: CCXI), today announced that, following consultations with the U.S. Food and Drug Administration (FDA), it filed an amendment to its New Drug Application (NDA) for avacopan for the treatment of Anti-neutrophil Cytoplasmic Autoantibody (ANCA)-associated vasculitis, addressing points raised during the FDA Advisory Committee meeting on May 6, 2021. The FDA has indicated that the filing constitutes a major amendment to the NDA and will result in the setting of a new PDUFA goal date of October 7, 2021. The NDA is primarily based on data from the Phase III ADVOCATE trial of avacopan for the treatment of ANCA-associated vasculitis. On May 6, the FDA’s Arthritis Advisory Committee voted 9-9 on whether the efficacy data support approval of avacopan, 10-8 that the safety profile of avacopan is adequate to support approval, and 10-8 that the benefit-risk profile is adequate to support approval of avacopan at the proposed dose of 30 mg twice daily.
“We appreciate the opportunity to put additional data and information before the Agency, information which we believe addresses many of the issues raised at the Advisory Committee meeting,” said Thomas J. Schall, Ph.D., President and Chief Executive Officer of ChemoCentryx. “We look forward to continuing discussions with the Agency.”
The Marketing Authorization Application (MAA) for avacopan in the treatment of ANCA-associated vasculitis was validated by the European Medicines Agency (EMA) in November 2020, and the Japanese New Drug Application was accepted for review by the Japanese Pharmaceuticals and Medical Device Agency in February 2021.
About ADVOCATE and ANCA-Associated Vasculitis
The ADVOCATE trial of avacopan was a global, randomized, double-blind, active-controlled, double-dummy Phase III trial of 331 patients with ANCA-associated vasculitis in 20 countries. Eligible study subjects were randomized to receive avacopan plus either rituximab or cyclophosphamide (followed by azathioprine/mycophenolate) or study-supplied oral prednisone plus either rituximab or cyclophosphamide (followed by azathioprine/mycophenolate). Subjects in both treatment groups could also receive non-protocol glucocorticoids if needed.
ANCA-associated vasculitis is a systemic disease in which over-activation of the complement pathway further activates neutrophils, leading to inflammation and destruction of small blood vessels. This results in organ damage and failure, with the kidney as the major target, and is fatal if not treated. Currently, treatment for ANCA-associated vasculitis consists of courses of non-specific immuno-suppressants (cyclophosphamide or rituximab), combined with the administration of daily glucocorticoids (steroids) for prolonged periods of time, which can be associated with significant clinical risk including death from infection.
About Avacopan
Avacopan is a first-in-class, orally-administered small molecule that employs a novel, highly targeted mode of action in the treatment of ANCA-associated vasculitis and other complement-driven autoimmune and inflammatory diseases. By precisely blocking the receptor (the C5aR) for the pro-inflammatory complement system fragment known as C5a on destructive inflammatory cells such as blood neutrophils, avacopan arrests the ability of those cells to do damage in response to C5a activation, which is known to be the driver of ANCA-associated vasculitis. Current therapies for ANCA-associated vasculitis and other related illnesses typically include broad immunosuppression with daily doses of glucocorticoids (steroids) such as prednisone or methylprednisone, which can cause significant illness and even death. Avacopan’s selective inhibition of only the C5aR leaves the beneficial C5a pathway through the C5L2 receptor functioning normally.
ChemoCentryx is also developing avacopan for the treatment of patients with C3 glomerulopathy (C3G) and hidradenitis suppurativa (HS). The U.S. Food and Drug Administration has granted avacopan orphan drug designation for ANCA-associated vasculitis and C3G. The European Commission has granted orphan medicinal product designation for avacopan for the treatment of two forms of ANCA-associated vasculitis: microscopic polyangiitis and granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis), as well as for C3G.
ChemoCentryx is responsible for the discovery and development of avacopan and owns and retains the commercial rights to the drug in the United States. ChemoCentryx’s Kidney Health Alliance with Vifor Pharma provides Vifor Pharma with exclusive rights to commercialize avacopan in markets outside of the U.S.
About ChemoCentryx
ChemoCentryx is a biopharmaceutical company developing new medications for inflammatory and autoimmune diseases and cancer. ChemoCentryx targets the chemokine and chemoattractant systems to discover, develop and commercialize orally-administered therapies. ChemoCentryx’s lead drug candidate, avacopan (CCX168), successfully completed a pivotal Phase III trial in ANCA-associated vasculitis and is in late stage clinical development for the treatment of severe Hidradenitis Suppurativa and C3 glomerulopathy (C3G). ChemoCentryx also has early stage drug candidates that target chemoattractant receptors in other inflammatory and autoimmune diseases and in cancer.
