[{"type":"text","content":"\nData from SPARTACUS and PROTECT OLE to show significant proteinuria reduction when replacing RASi with FILSPARI and when FILSPARI is used in combination with SGLT2i\n\n\nNew mechanistic data to show FILSPARI protects against IgA deposition in the kidney\n\n\n SAN DIEGO--(BUSINESS WIRE)--\nTravere Therapeutics, Inc., (Nasdaq: TVTX) today announced that the Company will present seven abstracts at the upcoming European Renal Association (ERA) Congress in Vienna, Austria, June 4-7.\n\n\nPresentations will include new data on the use of FILSPARI in IgA nephropathy (IgAN) from the Phase 2 SPARTACUS Study which demonstrated that FILSPARI provided clinically meaningful benefits in adults with IgAN who replaced their renin-angiotensin system inhibitor (RASi) with FILSPARI while receiving stable sodium-glucose cotransporter-2 inhibitor (SGLT2i) therapy. A presentation on results from the open label extension (OLE) of the Phase 3 PROTECT Study will show that patients previously treated with maximum labeled irbesartan experienced significant proteinuria reduction after switching to FILSPARI in the study.\n\n\nIn a preclinical model of IgAN, FILSPARI protected from mesangial deposition of IgA, suggesting a potential role of endothelin-1 and angiotensin II as modulators of disease activity in IgAN. Data from the gddY mouse model of IgAN will offer new insight into the pathogenesis of IgAN as a tissue-specific autoimmune disease.\n\n\nIn focal segmental glomerulosclerosis (FSGS), the Company will share a data analysis from the Phase 3 DUPLEX Study showing that partial and complete proteinuria remission were achieved earlier and more frequently with FILSPARI than irbesartan. The Company will also present preclinical data in an animal model of immune-mediated FSGS showing that optimized dual endothelin and angiotensin blockade with FILSPARI helps protect the integrity of the glomerular filtration barrier, reducing glomerular permeability and lowering albuminuria.\n\n\n“The breadth of data we’re presenting underscores our confidence in the role FILSPARI can serve as foundational therapy for rare kidney diseases,” said Jula Inrig, M.D., chief medical officer of Travere Therapeutics. “These findings provide further evidence that FILSPARI can decrease the risk of IgAN disease progression. We are deeply committed to advancing research and deliverin...
