In a regulatory blow to one of its key products in the European market, the European Medicines Agency's CHMP has recommended revoking the EU marketing authorization for TAVNEOS (avacopan), according to reports. The drug, used to treat ANCA-associated vasculitis, is marketed by Vifor Fresenius Medical Care Renal Pharma in partnership with CSL.
The recommendation follows an Article 20 non-pharmacovigilance procedure, though specific reasons remain undisclosed. TAVNEOS is a significant part of CSL's rare-disease portfolio, and its potential withdrawal could impact the company's revenue stream in the region. Markets are now awaiting the European Commission's final decision, which typically follows CHMP recommendations.
