TVTX - Travere Therapeutics to Present Abstracts at the 17th International Symposium on IgA Nephropathy (IIGANN 2023) | Benzinga
SAN DIEGO, Sept. 26, 2023 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc. (NASDAQ:TVTX) today announced that the Company and its collaborators will present preliminary findings from the SPARTAN Study evaluating the potential effect of FILSPARI® (sparsentan) as a first-line therapy in patients with newly diagnosed IgA nephropathy (IgAN) in a late-breaking trial session at the 17th International Symposium on IgA Nephropathy (IIGANN2023) in Ryogoku, Tokyo, September 28-30, 2023.
The Company will also present preclinical data supporting the nephroprotective mechanism of action of sparsentan, a dual endothelin angiotensin receptor antagonist, and an analysis of the UK National Registry of Rare Renal Diseases (RaDaR) which demonstrated that patients with IgAN traditionally considered ‘low-risk', with proteinuria less than one gram per day, had high rates of kidney failure.
"Patients with IgA nephropathy need both early and effective treatment options capable of significant and sustained reduction of proteinuria to preserve kidney function," said Jula Inrig, M.D., chief medical officer of Travere Therapeutics. "We're pleased to be presenting 24-week data on proteinuria reduction, blood pressure control, and safety from the ongoing SPARTAN Study evaluating the effect of sparsentan as a first-line treatment option in patients with newly diagnosed IgAN."

About IgA Nephropathy
IgA nephropathy (IgAN), also called Berger's disease, is a rare progressive kidney disease characterized by the buildup of immunoglobulin A (IgA), a protein that helps the body fight infections, in the kidneys. The deposits of IgA cause a breakdown of the normal filtering mechanisms in the kidney, leading to blood in the urine (hematuria), protein in the urine (proteinuria) and a progressive loss of kidney function. Other symptoms of IgAN may include swelling (edema) and high blood pressure.
IgAN is the most common type of primary glomerulonephritis worldwide and a leading cause of kidney failure due to glomerular disease. IgAN is estimated to affect up to 150,000 people in the US and is one of the most common glomerular diseases in Europe and Japan.
FILSPARI® (sparsentan) US Indication
FILSPARI is an endothelin and angiotensin II receptor antagonist indicated to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk of rapid disease progression, generally a UPCR ?1.5 g/g.
This indication is granted under accelerated approval based on reduction in proteinuria. It has not been established whether FILSPARI slows kidney function decline in patients with IgAN. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial.
FILSPARI® (sparsentan) Important Safety Information
BOXED WARNING: HEPATOTOXICITY AND EMBRYO-FETAL TOXICITY
Because of the risks of hepatotoxicity and birth defects, FILSPARI is available only through a restricted program called the FILSPARI REMS. Under the FILSPARI REMS, prescribers, patients and pharmacies must enroll in the program.
Hepatotoxicity
Some Endothelin Receptor Antagonists (ERAs) have caused elevations of aminotransferases, hepatotoxicity, and liver failure. In clinical studies, elevations in aminotransferases (ALT or AST) of at least 3-times the Upper Limit of Normal (ULN) have been observed in up to 2.5% of FILSPARI-treated patients, including cases confirmed with rechallenge.
Measure transaminases and bilirubin before initiating treatment and monthly for the first 12 months, and then every 3 months during treatment. Interrupt treatment and closely monitor patients who develop aminotransferase elevations more than 3x ULN.
FILSPARI should generally be avoided in patients with elevated aminotransferases (>3x ULN) at baseline because monitoring for hepatotoxicity may be more ...
