Key Notes

PDUFA originally January 13, 2026. Extended to April 13, 2026 after FDA received a major amendment to the sNDA in January 2026. Filspari is already approved for IgAN; FSGS approval would make it the first drug specifically indicated for FSGS. DUPLEX Phase 3 showed significant proteinuria reduction (did not meet primary eGFR slope endpoint over 108 weeks). AdCom initially planned — FDA later determined no AdCom needed.
