Vifor Pharma Press Release Chemocentryx Cma Withdrawal Aav

Companies plan to file for full marketing approval to EMA and FDA in 2020

MOUNTAIN VIEW, Calif. and ZURICH, 24 January, 2019 – ChemoCentryx, Inc. and Vifor Fresenius Medical Care Renal Pharma Ltd., a company of Vifor Pharma Group, today announced that in light of the upcoming availability of data from the pivotal Phase III ADVOCATE trial – the largest controlled trial in active anti-neutrophil cytoplasmic antibody associated vasculitis (ANCA-associated vasculitis) – they have decided to withdraw the application for Conditional Marketing Authorisation (CMA) of avacopan for the treatment of ANCA-associated vasculitis based on Phase II data. Efforts will now be exclusively directed to file integrated regulatory submissions in 2020 with the European Medicines Agency (EMA) and United States Food and Drug Administration (FDA) for full (unconditional) marketing approval, after the planned release of topline data from the Phase III ADVOCATE clinical trial anticipated already in the fourth quarter of 2019.

“Since pivotal topline data will be available from our global Phase III ADVOCATE trial later this year, we have decided not to proceed with our limited Phase II-based CMA in Europe,” said Thomas J. Schall, Ph.D., President and Chief Executive Officer of ChemoCentryx. “The pace of the worldwide ADVOCATE trial enrollment was considerably greater than originally anticipated when we applied for the European CMA; which was based on data from our Phase II CLEAR trial comprising 12 week dosing on some 67 patients. Since Phase III ADVOCATE assesses more than 300 ANCA vasculitis patients through 52 weeks of treatment, the imminent comprehensive data set will be much more powerful than those in the CMA application, therefore enabling a more consistent set of filings in Europe and the US. We would like to thank the Rapporteurs and the Committee for Medicinal Products for Human Use (CHMP) for the valuable support and guidance they provided to us as we look forward to topline ADVOCATE data in the fourth quarter this year.”

Stefan Schulze, President of the Executive Committee and Chief Operating Officer of Vifor Pharma Group, commented, “We strongly support the decision to focus on a full Market Authorisation. We believe this will offer regulators and the companies a much clearer view of the performance of avacopan in the treatment of ANCA-associated vasculitis, a group of rare kidney autoimmune diseases that lead to significant morbidity and mortality, and where there is a clear unmet need for safer and more efficacious therapies.”

About Avacopan
Avacopan is an orally-administered small molecule that is a selective inhibitor of the complement C5a receptor, or C5aR. Avacopan is in Phase III development for the treatment of anti-neutrophil cytoplasmic auto-antibody-associated vasculitis (ANCA-associated vasculitis). In clinical studies to date, avacopan was shown to be well tolerated and provided effective control of the disease while allowing elimination of high-dose steroids, part of the current standard of care. 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, C3G and atypical hemolytic uremic syndrome (aHUS). 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. Avacopan was also granted access to the European Medicines Agency's (EMA) PRIority MEdicines (PRIME) initiative, which supports accelerated assessment of investigational therapies addressing unmet medical need. ChemoCentryx's Kidney Health Alliance with Vifor Pharma provides Vifor Pharma with exclusive rights to commercialise avacopan and CCX140 in markets outside of the U.S. ChemoCentryx also has early stage drug candidates that target chemoattractant receptors in other inflammatory and autoimmune diseases and in cancer.
