About Atrasentan
Atrasentan is a selective and potent inhibitor of the endothelin A receptor (ETA) that has the potential to provide benefit in multiple chronic kidney diseases by reducing proteinuria and having direct anti-inflammatory and anti-fibrotic effects to preserve kidney function. IgAN was identified as the lead indication for evaluation of atrasentan due to the role of ETA activation in driving proteinuria, mesangial cell activation, kidney inflammation and fibrosis, the hallmarks of IgAN disease progression. The pivotal phase 3 ALIGN trial of atrasentan is currently enrolling patients with IgAN and the phase 2 AFFINITY trial of atrasentan is currently enrolling patients with proteinuric glomerular diseases.
About IgA Nephropathy (IgAN)
Immunoglobulin A nephropathy (IgAN) is the most common primary glomerular disease globally and a leading cause of chronic kidney disease (CKD), with up to 45 percent of IgAN patients progressing to end-stage renal disease (ESRD), requiring dialysis or kidney transplantation. There are currently no approved therapies for IgAN and only limited treatment options for high-risk patients. IgAN is characterized by the deposition of IgA-containing immune complexes in the glomeruli of the kidney, which initiates an inflammatory response that results in protein and blood leaking into the urine, called proteinuria and hematuria, respectively. Proteinuria levels are the strongest predictor of kidney function loss and clinical outcomes in IgAN patients, and lowering proteinuria is associated with important clinical benefit. Blockade of the endothelin A receptor by atrasentan has potential to reduce proteinuria as well as kidney inflammation and fibrosis to preserve kidney function in IgAN.
