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 U.S. and is one of the most common glomerular diseases in Europe and Japan. About Focal Segmental Glomerulosclerosis Focal segmental glomerulosclerosis (FSGS) is a rare proteinuric kidney disorder in children and adults that is estimated to affect more than 40,000 patients in the U.S., with similar prevalence in Europe. The disorder is defined by progressive scarring of the kidney and often leads to kidney failure. FSGS is characterized by proteinuria, where protein leaks into the urine due to a breakdown of the normal filtration mechanism in the kidney. Once in the urine, protein is toxic to other parts of the kidney, especially the tubules, and is believed to contribute to further disease progression. Other common symptoms include swelling in parts of the body, known as edema, as well as low blood albumin levels, abnormal lipid profiles and hypertension. Sparsentan is not approved for use in FSGS. There are currently no FDA-approved pharmacologic therapies for FSGS. About Travere Therapeutics At Travere Therapeutics, we are in rare for life.

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 3.5% 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 difficult and these patients may be at increased risk for serious hepatotoxicity. Embryo-Fetal Toxicity FILSPARI can cause major birth defects if used by pregnant patients based on animal data. Therefore, pregnancy testing is required before the initiation of treatment, during treatment and one month after discontinuation of treatment with FILSPARI. Patients who can become pregnant must use effective contraception before the initiation of treatment, during treatment, and for one month after discontinuation of treatment with FILSPARI. Contraindications FILSPARI is contraindicated in patients who are pregnant. Do not coadminister FILSPARI with angiotensin receptor blockers (ARBs), ERAs, or aliskiren. Warnings and Precautions Hepatotoxicity: Elevations in ALT or AST of at least 3-fold ULN have been observed in up to 3.5% of FILSPARI-treated patients, including cases confirmed with rechallenge. While no concurrent elevations in bilirubin >2-times ULN or cases of liver failure were observed in FILSPARI-treated patients, some ERAs have caused elevations of aminotransferases, hepatotoxicity, and liver failure. To reduce the risk of potential serious hepatotoxicity, measure serum aminotransferase levels and total bilirubin prior to initiation of treatment and monthly for the first 12 months, then every 3 months during treatment. Advise patients with symptoms suggesting hepatotoxicity (nausea, vomiting, right upper quadrant pain, fatigue, anorexia, jaundice, dark urine, fever, or itching) to immediately stop treatment with FILSPARI and seek medical attention. If aminotransferase levels are abnormal at any time during treatment, interrupt FILSPARI and monitor as recommended. Consider re-initiation of FILSPARI only when hepatic enzyme levels and bilirubin return to pretreatment values and only in patients who have not experienced clinical symptoms of hepatotoxicity. Avoid initiation of FILSPARI in patients with elevated aminotransferases (>3x ULN) prior to drug initiation because monitoring hepatotoxicity in these patients may be more difficult and these patients may be at increased risk for serious hepatotoxicity. Embryo-Fetal Toxicity: FILSPARI can cause fetal harm when administered to a pregnant patient and is contraindicated during pregnancy. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test prior to initiation of treatment with FILSPARI, monthly during treatment, and one month after discontinuation of treatment. Advise patients who can become pregnant to use effective contraception prior to initiation of treatment, during treatment, and for one month after discontinuation of treatment with FILSPARI. FILSPARI REMS: Due to the risk of hepatotoxicity and embryo-fetal toxicity, FILSPARI is available only through a restricted program called the FILSPARI REMS. Prescribers, patients, and pharmacies must be enrolled in the REMS program and comply with all requirements ( www.filsparirems.com ). Hypotension: Hypotension has been observed in patients treated with ARBs and ERAs. There was a greater incidence of hypotension-associated adverse events, some serious, including dizziness, in patients treated with FILSPARI compared to irbesartan. In patients at risk for hypotension, consider eliminating or adjusting other antihypertensive medications and maintaining appropriate volume status. If hypotension develops, despite elimination or reduction of other antihypertensive medications, consider a dose reduction or dose interruption of FILSPARI. A transient hypotensive response is not a contraindication to further dosing of FILSPARI, which can be given once blood pressure has stabilized. Acute Kidney Injury: Monitor kidney function periodically. Drugs that inhibit the renin-angiotensin system (RAS) can cause kidney injury. Patients whose kidney function may depend in part on the activity of the RAS (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute kidney injury on FILSPARI. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in kidney function while on FILSPARI. Hyperkalemia: Monitor serum potassium periodically and treat appropriately. Patients with advanced kidney disease, taking concomitant potassium-increasing drugs (e.g., potassium supplements, potassium-sparing diuretics), or using potassium-containing salt substitutes are at increased risk for developing hyperkalemia. Dosage reduction or discontinuation of FILSPARI may be required. Fluid Retention: Fluid retention may occur with ERAs, and has been observed in clinical studies with FILSPARI. FILSPARI has not been evaluated in patients with heart failure. If clinically significant fluid retention develops, evaluate the patient to determine the cause and the potential need to initiate or modify the dose of diuretic treatment then consider modifying the dose of FILSPARI. Most common adverse reactions The most common adverse reactions (≥5%) are hyperkalemia, hypotension (including orthostatic hypotension), peripheral edema, dizziness, anemia, and acute kidney injury. Drug interactions Renin-Angiotensin System (RAS) Inhibitors and ERAs: Do not coadminister FILSPARI with ARBs, ERAs, or aliskiren due to increased risks of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure). Strong and Moderate CYP3A Inhibitors: Avoid concomitant use of FILSPARI with strong CYP3A inhibitors. If a strong CYP3A inhibitor cannot be avoided, interrupt FILSPARI treatment. When resuming treatment with FILSPARI, consider dose titration. Monitor blood pressure, serum potassium, edema, and kidney function regularly when used concomitantly with moderate CYP3A inhibitors. Concomitant use with a strong CYP3A inhibitor increases sparsentan exposure which may increase the risk of FILSPARI adverse reactions. Strong CYP3A Inducers: Avoid concomitant use with a strong CYP3A inducer. Concomitant use with a strong CYP3A inducer decreases sparsentan exposure which may reduce FILSPARI efficacy. Antacids and Acid Reducing Agents: Administer FILSPARI 2 hours before or after administration of antacids. Avoid concomitant use of acid reducing agents (histamine H2 receptor antagonist and PPI proton pump inhibitor) with FILSPARI. Sparsentan exhibits pH-dependent solubility. Antacids or acid reducing agents may decrease sparsentan exposure which may reduce FILSPARI efficacy. Non-Steroidal Anti-Inflammatory Agents (NSAIDs), Including Selective Cyclooxygenase-2 (COX-2) Inhibitors: Monitor for signs of worsening renal function with concomitant use with NSAIDs (including selective COX-2 inhibitors). In patients with volume depletion (including those on diuretic therapy) or with impaired kidney function, concomitant use of NSAIDs (including selective COX-2 inhibitors) with drugs that antagonize the angiotensin II receptor may result in deterioration of kidney function, including possible kidney failure. CYP2B6, 2C9, and 2C19 Substrates: Monitor for efficacy of concurrently administered CYP2B6, 2C9, and 2C19 substrates and consider dosage adjustment in accordance with the Prescribing Information. Sparsentan decreases exposure of these substrates, which may reduce efficacy related to these substrates. P-gp and BCRP Substrates: Avoid concomitant use of sensitive substrates of P-gp and BCRP with FILSPARI. Sparsentan may increase exposure of these transporter substrates, which may increase the risk of adverse reactions related to these substrates. Agents Increasing Serum Potassium: Monitor serum potassium frequently in patients treated with FILSPARI and other agents that increase serum potassium. Concomitant use of FILSPARI with potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes, or other drugs that raise serum potassium levels may result in hyperkalemia.

First non-immunosuppressive dual-action therapy recommended by NICE for eligible patients with IgA nephropathy, a leading cause of kidney failure 1-3 NICE's recommendation is based on clinically meaningful results from the phase-III PROTECT trial 4 ST. GALLEN, Switzerland, May 23, 2025 /PRNewswire/ -- CSL Vifor is pleased to announce that the National Institute for Health and Care Excellence (NICE) has published final draft guidance recommending that sparsentan can be used in the NHS in England as an option to treat primary IgA nephropathy in adults with a urine protein excretion of 1.0 g/day or more, or a urine protein-to-creatinine ratio of 0.75 g/g or more.3 NICE has provided guidance to ensure that only patients responding to treatment continue.3 The decision follows authorisation from the UK's Medicines and Healthcare products Regulatory Agency (MHRA) in April 2025.5 What this means in practice is that there is enough evidence to show that sparsentan provides benefits and value for money, so it can be used routinely if it is considered the most suitable treatment option in this population.3 Sparsentan must be funded in England within 90 days of final publication of this guidance3 which is expected to be 27 June 2025. Professor Jonathan Barratt, Professor of Renal Medicine at University Leicester, UK, welcomed the NICE decision as a major advancement in the treatment of IgA nephropathy in the UK. "IgA nephropathy is a condition with an average age at diagnosis of around 40 years.6 Due to disease progression, a patient's kidneys may fail. Treatments, such as sparsentan, that have been developed for IgA nephropathy are urgently needed, our goal being to improve outcomes for these patients." IgA nephropathy is characterised by the buildup of a faulty version of immunoglobulin A (IgA), which accumulates in clusters in small blood vessels in the kidney, called glomeruli, that filter the blood. These clumps damage the glomeruli causing leakage of blood (haematuria) and protein (proteinuria) into the urine resulting in a progressive loss of kidney function. Proteinuria is a major risk factor for IgA nephropathy progression, increasing the risk of kidney failure.6-8 Despite current treatments, some patients with IgA nephropathy do not achieve adequate proteinuria reduction and remain at risk of progression.9 Although classified as rare, IgA nephropathy is the most common type of primary glomerular disease worldwide, with over 22,000 adults estimated to have the condition in England.10 Patients generally face a poor prognosis if the condition is not appropriately controlled, with approximately 30-40% of patients developing kidney failure within 10 years of diagnosis.11 Current medical treatment guidelines by KDIGO (Kidney Disease, Improving Global Outcomes) state that patients who are at high risk of progressive chronic kidney disease, despite maximal supportive care, are those with persistent urine protein excretion >1 g/day.12 Underscoring the importance of the NICE recommendation for IgA nephropathy patients and their communities, Dr. Vinicius Gomes De Lima, Head of Global Medical Affairs at CSL Vifor said: "We are very pleased that NICE recognised the value of our innovative therapy which helps to address a clear unmet medical need in patients with IgA nephropathy. We look forward to working with the National Health Service to ensure access to this important medicine as soon as possible as we continue to deliver on our promise to patients." CSL Vifor expects to launch sparsentan in the UK in the second half of 2025; commercial stock will be available from July 2025. Notes to Editors On 15th April 2025, the MHRA granted the marketing authorisation for sparsentan based on the final results of the Phase 3 PROTECT double blind study.5 About CSL Vifor CSL Vifor is a global partner of choice for pharmaceuticals and innovative, leading therapies in iron deficiency and nephrology.

About IgA nephropathy Primary immunoglobulin A nephropathy (IgA nephropathy) is a rare, progressive type of chronic kidney disease (CKD) that is often diagnosed in adults before the age of 40 years.6 CKD is characterised by abnormalities of kidney function or structure that have been present for more than three months and can be categorised into five stages dependent on functionality of the kidney.13 Dialysis (a medical treatment used to artificially filter waste products and excess fluids from the blood when the kidneys are unable to perform this function adequately)14 or kidney transplantation is recommended for patients whose kidneys have reached an advanced stage (typically, stage 5).15 More than 60 per cent of adult patients diagnosed with IgA nephropathy are in CKD stage 3 or higher.6 Patients with this condition may experience blood in the urine (red or dark brown urine), foamy urine from protein leaking into the urine, flank pain, swelling (oedema), high blood pressure, and fatigue.16 About FILSPARI® (sparsentan) Sparsentan was developed by Travere Therapeutics and has been granted Orphan Drug Designation for the treatment of IgA nephropathy in the UK, Europe and the U.S. Sparsentan is currently available in the U.S. and first markets in Europe. CSL Vifor has been granted exclusive commercialisation rights for sparsentan in Europe, Australia and New Zealand. Sparsentan is anticipated to be available to patients in the UK in the second half of 2025. Sparsentan is the first and only non-immunosuppressive treatment for IgA nephropathy that has two modes of action.1 This single molecule functions as a high affinity, dual-acting antagonist of both the endothelin A receptor (ETAR) and the angiotensin II subtype 1 receptor (AT1R).4 Sparsentan inhibits activation of both ETAR and AT1R, both of which play a role in regulating processes in the kidney, such as inflammation, that lead to progression of kidney damage.4 About PROTECT NICE's recommendation is based on data from the pivotal Phase 3 PROTECT study4 of sparsentan in IgA nephropathy, one of the largest interventional studies to date in IgA nephropathy and the only head-to-head trial in this rare kidney disease. It is a global, randomised, multicentre, double-blind, parallel-arm, active-controlled clinical trial evaluating the safety and efficacy of 400 mg of sparsentan, compared to 300 mg of irbesartan (an angiotensin II receptor blocker(ARB)), in 404 patients ages 18 years and up with IgA nephropathy and persistent proteinuria despite receiving at least 50% of maximum label dose and maximally tolerated angiotensin-converting enzyme (ACE) inhibitors or ARB therapy.4,17 The PROTECT study met its primary endpoint at the pre-specified interim analysis with statistical significance.4 After 36 weeks of treatment, patients receiving sparsentan (n=202) achieved a mean reduction in proteinuria from baseline of 49.8 percent, compared to a mean reduction in proteinuria from baseline of 15.1 percent for irbesartan-treated patients (n=202).4,17 Treatment emergent adverse events and serious adverse events were well-balanced between sparsentan and irbesartan, except for dizziness (30 [15%] vs 13 [6%] patients) and hypotension (26 (13%] vs eight (4%] patients).4 For more information, please refer to the Summary of Product Characteristics (SmPC).18,19 References: Trachtman H, et al.
