Vera’s Trutakna wins FDA nod as first dual inhibitor for IgAN Vera Therapeutics Inc. looks to get an almost five-month head start over a competitor, Vertex Pharmaceuticals Inc., as the U.S. FDA cleared its Trutakna (atacicept) as the first dual BAFF/APRIL inhibitor for treating immunoglobulin A nephropathy (IgAN). The accelerated approval, which came on the July 7 PDUFA date, indicates Trutakna for use in reducing proteinuria in adults with primary IgAN at risk for disease progression.
