Abstract

BACKGROUND: Atrasentan, a selective endothelin A receptor antagonist, reduced proteinuria in the prespecified interim analysis (week 36) of the ALIGN trial in adults with IgA nephropathy. We assessed whether atrasentan slowed estimated glomerular filtration rate (eGFR) decline after 2·5 years' treatment.

METHODS: We performed a randomised, double-blind, placebo-controlled, phase 3 trial (133 sites, 20 countries). Adults with biopsy-proven IgA nephropathy, eGFR of at least 30 mL/min per 1·73 m

FINDINGS: Between March 15, 2021, and April 28, 2023, 404 participants were randomly assigned (main stratum: 340; SGLT2 inhibitor stratum: 64). In the main stratum, change from baseline in eGFR at week 136 was -7·5 mL/min per 1·73 m

INTERPRETATION: Atrasentan reduced proteinuria and preserved kidney function after 2·5 years. This effect was present with or without concomitant SGLT2 inhibitor use. Atrasentan was well tolerated.
