Received 693 new patient start forms for FILSPARI® (sparsentan) in the fourth quarter of 2024; approximately $50 million in preliminary net product sales of FILSPARI for the fourth quarter sNDA requesting modification of liver monitoring for FILSPARI in IgAN accepted for review by FDA; PDUFA target action date of August 28, 2025 Company remains on track to provide regulatory update on sparsentan in FSGS by its fourth quarter 2024 earnings call SAN DIEGO, Jan. 13, 2025 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc., (NASDAQ: TVTX) today announced that, based on preliminary and unaudited financial data, the Company expects net product sales for the fourth quarter of 2024 to be approximately $74 million. For the fiscal year 2024, the Company expects net product sales to be approximately $227 million. The Company ended 2024 with approximately $371 million in cash, cash equivalents, and marketable securities. The Company also provided an update on key corporate, clinical, and regulatory development initiatives, including anticipated 2025 milestones. “The fourth quarter capped a tremendous year of execution for Travere. Following full approval of FILSPARI in September, the ongoing U.S. commercial launch resulted in nearly 700 new patient start forms in the fourth quarter as well as a 40% increase in FILSPARI net product sales compared to the third quarter,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “As we look ahead to the new year, we expect to help even more patients with IgAN through continued strong commercial execution, the final publication of the updated KDIGO guidelines and potential approval of the recently accepted sNDA to modify liver monitoring for FILSPARI. Beyond IgAN, we believe that sparsentan has the potential to become an important new medicine for people with FSGS, and we remain on track to provide an update on our interactions with FDA to establish a potential regulatory pathway for this additional indication by our fourth quarter 2024 earnings call.” Program Updates and Anticipated 2025 Milestones FILSPARI® (sparsentan) – IgA Nephropathy (IgAN) In the fourth quarter of 2024, the Company received 693 new patient start forms (PSFs), driven by growth amongst new and repeat prescribers following full approval by the U.S. Food and Drug Administration (FDA) on September 5, 2024. Preliminary net product sales of FILSPARI in the fourth quarter of 2024 were approximately $50 million; $132 million for the full year 2024. The FDA recently accepted for review the Company’s supplemental New Drug Application (sNDA) requesting modification of liver monitoring for FILSPARI in IgAN and assigned a PDUFA target action date of August 28, 2025. In 2025, the Company anticipates final publication of the updated Kidney Disease Improving Global Outcomes (KDIGO) clinical guidelines for IgAN. The draft guidelines published in August 2024 recommended FILSPARI as a foundational kidney-targeted therapy and lowered the targeted proteinuria level for all IgAN patients to under 0.5 g/day or ideally complete remission (under 0.3 g/day). In 2025, the Company anticipates presenting additional data from its ongoing clinical studies to further support FILSPARI as foundational therapy in treating patients with IgAN. The Company’s collaborator CSL Vifor has launched FILSPARI for the treatment of IgAN in Germany, Austria, and Switzerland. FILSPARI also recently received approval in the UK. In 2025, the Company and CSL Vifor anticipate the current conditional marketing authorization (CMA) for FILSPARI for the treatment of IgAN in Europe will be converted to full approval. The Company expects to receive a $17.5 million milestone payment from CSL Vifor upon conversion of the CMA to full approval, and the Company remains eligible to receive additional milestone payments related to market access and sales-based achievements. In the second half of 2025, Travere’s partner Renalys Pharma, Inc. expects topline results from its registrational Phase 3 clinical trial of sparsentan for the treatment of IgA nephropathy in Japan. Sparsentan – Focal Segmental Glomerulosclerosis (FSGS) The Company remains on track to provide an update on interactions with the FDA regarding a potential regulatory pathway for a sparsentan FSGS indication by its fourth quarter 2024 earnings call. Pegtibatinase – Classical Homocystinuria (HCU) The Company is making progress on necessary process improvements in manufacturing scale-up and is on track to restart enrollment in the Phase 3 HARMONY Study in 2026. The Company expects to announce complete full year 2024 financial results and provide a corporate update in February.

FILSPARI® (sparsentan) U.S. Indication FILSPARI (sparsentan) is indicated to slow kidney function decline in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk for disease progression. 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.
