Atrasentan Shows Long-Term Kidney Benefits in IgA Nephropathy Trials
Final phase 3 trial results show atrasentan (Vanrafia®) provides significant long-term kidney function benefits in IgA nephropathy patients, with a 2.59 mL/min/1.73m² eGFR improvement versus placebo. Earlier phase 2 data demonstrated the drug reduces proteinuria by 30.7% when added to standard background therapy. The drug's manufacturer plans to seek traditional FDA approval in 2026 based on these findings.
