About TARPEYO®/Kinpeygo®
TARPEYO® is an oral 4mg delayed-release formulation of budesonide, designed to dissolve in the pH of the distal ileum. Each capsule contains coated beads of budesonide that target mucosal B-cells present in the ileum, including the Peyer's patches, which are responsible for the production of galactose-deficient IgA1 antibodies (Gd-Ag1), causing IgA nephropathy.
About Primary Immunoglobulin A Nephropathy
Primary immunoglobulin A nephropathy (IgA nephropathy or IgAN or Berger's Disease) is a rare, progressive, chronic autoimmune disease that attacks the kidneys and occurs when galactose-deficient IgA1 is recognized by autoantibodies, creating IgA1 immune complexes that become deposited in the glomerular mesangium of the kidney. This deposition in the kidney can lead to progressive kidney damage, potentially resulting in end-stage kidney disease. IgAN most often develops between late teens and late 30s.
