Submission is based on 2-year confirmatory results from the Phase 3 PROTECT Study in which FILSPARI demonstrated a significant reduction in proteinuria, preservation of kidney function and a generally well-tolerated safety pro with active control irbesartan SAN DIEGO, March 11, 2024 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc. (Nasdaq: TVTX) today announced the submission of a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for conversion of the existing U.S. accelerated approval of FILSPARI® (sparsentan) in IgA nephropathy (IgAN) to full approval. In February 2023, the FDA granted accelerated approval to FILSPARI as the first and only non-immunosuppressive treatment targeting glomerular injury in the kidney to reduce proteinuria in adults with primary IgAN at risk of rapid disease progression. The sNDA is based on 2-year confirmatory results from the Phase 3 PROTECT Study, the only head-to-head study in IgAN versus an active comparator. “Since being introduced under accelerated approval, FILSPARI has positively impacted the lives of many people living with IgAN. The submission of the sNDA is an important step toward potentially gaining full approval in IgAN in support of reaching more people living with this devastating rare kidney disease,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “FILSPARI is at the forefront of emerging new treatment options providing hope for a delay in kidney transplant or dialysis. The results from the pivotal Phase 3 PROTECT Study show that by directly targeting glomerular injury in the kidney with FILSPARI, patients can achieve sustained proteinuria reduction and long-term kidney function preservation. We look forward to working with the FDA throughout the upcoming review process.” FILSPARI is a once-daily, oral medication that directly targets glomerular injury in the kidney by blocking two critical pathways of IgAN disease progression (endothelin-1 and angiotensin II). FILSPARI is also the first and only non-immunosuppressive therapy approved for the treatment of this rare kidney disease. The sNDA submission is supported by results from the Phase 3 PROTECT Study that showed that FILSPARI demonstrated long-term kidney function preservation and achieved a significant reduction in proteinuria and a clinically meaningful difference in eGFR slope versus an active comparator. The FDA has 60 days from the receipt of the application to determine whether to accept it for review. The Company expects to receive notice regarding the acceptance for review of the sNDA submission as well as the timeline for sNDA review from the FDA in the second quarter of 2024. In addition to the sNDA submission to the FDA, the Company and its European commercial partner CSL Vifor recently announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended approval of the conditional marketing authorization (CMA) for sparsentan for the treatment of IgA nephropathy (IgAN) in Europe. A decision by the European Commission is expected in the second quarter of 2024. If approved, sparsentan would receive a CMA in all member states of the European Union, as well as in Iceland, Liechtenstein, and Norway. 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 U.S. and is one of the most common glomerular diseases in Europe and Japan. About the PROTECT Study The PROTECT Study is one of the largest interventional studies to date in IgA nephropathy (IgAN) and the only head-to-head trial in this rare kidney disease. It is a global, randomized, multicenter, double-blind, parallel-arm, active-controlled clinical trial evaluating the safety and efficacy of 400 mg of sparsentan, compared to 300 mg of irbesartan, in 404 patients ages 18 years and up with IgAN and persistent proteinuria despite receiving at least 50% of max label dose and maximally tolerated ACE or ARB therapy. In August 2021, the Company announced the PROTECT Study met its pre-specified interim primary efficacy endpoint with statistical significance. Based on the pre-specified, primary analyses set, after 36 weeks of treatment, patients receiving sparsentan achieved a mean reduction in proteinuria from baseline of 49.8%, compared to a mean reduction in proteinuria from baseline of 15.1% for irbesartan-treated patients (p<0.0001). The study’s confirmatory secondary endpoint in the U.S. is estimated glomerular filtration rate (eGFR) total slope from day 1 to week 110 of treatment. The confirmatory secondary endpoint in the EU is eGFR chronic slope from week 6 to week 110 of treatment, following the initial acute effect of randomized treatment. Following the 110-week blinded treatment period, treatment with study medication was discontinued for 4 weeks -- at this time, the investigator resumed standard of care treatment. In September 2023, the Company announced topline two-year confirmatory secondary endpoint results from the PROTECT Study of sparsentan in IgAN. Sparsentan demonstrated long-term kidney function preservation and achieved a clinically meaningful difference in eGFR total and chronic slope versus irbesartan, narrowly missing statistical significance in eGFR total slope while achieving statistical significance in eGFR chronic slope for purposes of regulatory review in the EU. Patients who completed the PROTECT double-blind portion of the study on treatment were eligible to participate in the open-label extension of the trial.

For more information, visit travere.com FILSPARI® (sparsentan) U.S. 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 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. To reduce the risk of potential serious hepatotoxicity, measure serum aminotransferase levels and total bilirubin prior to initiation of treatment, 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. Embryo-Fetal Toxicity: FILSPARI can cause fetal harm. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test and advise patients who can become pregnant to use effective contraception prior to, during, and one month after discontinuation of FILSPARI treatment. FILSPARI REMS: FILSPARI is available only through a restricted program under a REMS called the FILSPARI REMS. Important requirements include: — Prescribers must be certified with the FILSPARI REMS by enrolling and completing training. — All patients must enroll in the FILSPARI REMS prior to initiating treatment and comply with monitoring requirements. — Pharmacies that dispense FILSPARI must be certified with the FILSPARI REMS and must dispense only to patients who are authorized to receive FILSPARI. Further information is available at or 1-833-513-1325. Hypotension: 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, consider a dose reduction or dose interruption of FILSPARI. Acute Kidney Injury: Monitor kidney function periodically. Patients whose kidney function may depend in part on the activity of the renin-angiotensin system (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 with FILSPARI. If clinically significant fluid retention develops, after evaluation, consider modifying the dose of FILSPARI. Most common adverse reactions (5%) with FILSPARI are peripheral edema, hypotension (including orthostatic hypotension), dizziness, hyperkalemia, and anemia. Drug interactions Renin-Angiotensin System (RAS) Inhibitors and ERAs: Do not coadminister FILSPARI with angiotensin receptor blockers (ARBs), ERAs, or aliskiren. Strong and Moderate CYP3A Inhibitors: Avoid concomitant use of FILSPARI with strong CYP3A inhibitors. Monitor blood pressure, serum potassium, edema, and kidney function regularly when used concomitantly with moderate CYP3A inhibitors. Strong CYP3A Inducers: Avoid concomitant use with a strong CYP3A inducer. 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. Non-Steroidal Anti-Inflammatory Agents (NSAIDs), Including Selective Cyclooxygenase-2 (COX-2) Inhibitors: Monitor for signs of worsening renal function. CYP2B6, 2C9, and 2C19 Substrates: Monitor for efficacy of the concurrently administered CYP2B6, 2C9, and 2C19 substrates and consider dosage adjustment in accordance with the Prescribing Information. P-gp and BCRP Substrates: Avoid concomitant use of sensitive substrates of P-gp and BCRP with FILSPARI. Agents Increasing Serum Potassium: Monitor serum potassium frequently. 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. Use in specific populations Pregnancy / Females and Males of Reproductive Potential: FILSPARI can cause fetal harm, including birth defects and fetal death, when administered to a pregnant patient and is contraindicated during pregnancy. Pregnancy Testing / Contraception: Verify the pregnancy status and effective method of contraception prior to, during, and one month after discontinuation of FILSPARI treatment. The patient should contact their physician immediately for pregnancy testing if onset of menses is delayed or pregnancy is suspected. Lactation: Advise patients not to breastfeed during treatment with FILSPARI. Hepatic Impairment: Avoid use of FILSPARI in patients with any hepatic impairment (Child-Pugh class A-C).

Received 459 new patient start forms (PSFs) for FILSPARI® (sparsentan) in Q4 2023; Total of 1,452 PSFs received in 2023 Company nearing submission of sNDA to convert U.S. accelerated approval of FILSPARI in IgAN to full approval CHMP opinion on potential approval in Europe for sparsentan in IgAN anticipated in Q1 2024 Pivotal Phase 3 HARMONY Study of pegtibatinase in classical homocystinuria (HCU) enrolling; topline data anticipated in 2026 Net product sales of $39.9 million for Q4 2023; $127.5 million for FY 2023 Cash, cash equivalents, and marketable securities as of December 31, 2023, totaled $566.9 million SAN DIEGO, Feb. 15, 2024 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc. (NASDAQ: TVTX) today reported its fourth quarter and full year 2023 financial results and provided a corporate update. “With ongoing growth in demand for FILSPARI in IgAN and the initiation of the pivotal Phase 3 program of pegtibatinase in HCU, we have made strong progress towards our goal of breaking down barriers in rare kidney and metabolic diseases where there has historically been little innovation,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. "As we enter 2024, our top priority remains furthering the strength of the U.S. commercial launch of FILSPARI in IgAN. With the potential full approval of FILSPARI, anticipated inclusion into the global treatment guidelines for IgAN as well as additional data planned in 2024, we are well-positioned to build upon our current momentum. Additionally, with a potential conditional marketing approval of FILSPARI for IgAN in the EU and development progress in Japan, we look to make sound progress with our foreign partners towards the shared goal of reaching patients outside of the U.S. Beyond FILSPARI, we look forward to advancing the innovative Phase 3 HARMONY Study of pegtibatinase, which is designed to ultimately deliver the first disease modifying therapy for people living with HCU.” Financial Results for Continuing Operations for the Quarter Ended December 31, 2023 The following financial results discussion compares Travere’s continuing operations. All periods unless otherwise specified have been adjusted to exclude discontinued operations related to the divestiture of the bile acid product portfolio completed on August 31, 2023. Net product sales for the fourth quarter of 2023 were $39.9 million, compared to $25.8 million for the same period in 2022. For the full year 2023, net product sales were $127.5 million, compared to $98.0 million for the same period in 2022. The increase is primarily attributable to sales from the ongoing commercial launch of FILSPARI. Research and development (R&D) expenses for the fourth quarter of 2023 were $59.7 million, compared to $58.1 million for the same period in 2022. For the full year 2023, R&D expenses were $245.0 million, compared to $227.3 million for the same period in 2022. The difference is largely attributable to the continued advancement of the Company’s pegtibatinase clinical program, including clinical trial expenses and manufacturing, as well as increased headcount. On a non-GAAP adjusted basis, R&D expenses were $55.3 million for the fourth quarter of 2023, compared to $52.0 million for the same period in 2022. Selling, general, and administrative (SG&A) expenses for the fourth quarter of 2023 were $63.6 million, compared to $57.1 million for the same period in 2022. For the full year 2023, SG&A expenses were $265.5 million, compared to $197.5 million for the same period in 2022. The difference is largely attributable to commercial launch related activities following the accelerated approval of FILSPARI in February 2023, as well as legal fees. On a non-GAAP adjusted basis, SG&A expenses were $49.7 million for the fourth quarter of 2023, compared to $44.3 million for the same period in 2022. Total other income, net, for the fourth quarter of 2023 was $5.7 million, compared to $1.1 million for the same period in 2022. The difference is largely attributable to an increase in interest income during the period. Net loss including discontinued operations for the fourth quarter of 2023 was $90.2 million, or $1.18 per basic share, compared to a net loss of $65.8 million, or $1.03 per basic share for the same period in 2022. For the full year 2023, net loss including discontinued operations was $111.4 million, compared to $278.5 million for the same period in 2022. On a non-GAAP adjusted basis, net income including discontinued operations for the fourth quarter of 2023 was $71.8 million, or $0.94 per basic share, compared to a net loss of $46.9 million, or $0.73 per basic share for the same period in 2022. As of December 31, 2023, the Company had cash, cash equivalents, and marketable securities of $566.9 million. Program Updates and Anticipated Milestones FILSPARI® (sparsentan) – IgAN On February 17, 2023, the U.S. Food and Drug Administration (FDA) granted accelerated approval to FILSPARI to reduce proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/g. FILSPARI became commercially available the week of February 27, 2023. Commercial progress in the ongoing launch has resulted in: 459 new patient start forms (PSFs) received in the fourth quarter of 2023; as of December 31, 2023 a total of 1,452 PSFs had been received since approval.Net product sales of $14.7 million during the fourth quarter, bringing the total to $29.2 million in net product sales since the beginning of the launch. The Company expects to submit a supplemental New Drug Application (sNDA) in the first quarter of 2024 for conversion of the existing U.S. accelerated approval of FILSPARI to full approval.The Company and its collaborator CSL Vifor anticipate a review opinion by the Committee for Medicinal Products for Human Use (CHMP) on the potential approval of the Conditional Marketing Authorization (CMA) application for sparsentan for the treatment of IgAN in Europe in the first quarter of 2024. If approved, sparsentan would receive CMA in all member states of the European Union, as well as in Iceland, Liechtenstein, and Norway.In January 2024, the Company announced that it had entered into an exclusive licensing agreement with Renalys Pharma, Inc., to bring sparsentan to patients in Japan and other countries in Asia. Following successful meetings with the Pharmaceuticals and Medical Devices Agency (PMDA) in 2023, Renalys plans to initiate an open label registrational study of sparsentan in Japan in the second quarter of 2024 to support potential approval of sparsentan in Japan. Results from the urine protein/creatinine ratio (UP/C) endpoint in the study are expected in the second half of 2025. In 2024, the Company expects additional data from its ongoing open-label studies evaluating the safety and efficacy of sparsentan in combination with sodium glucose cotransporter-2 inhibitors (SGLT2i) as well as from the ongoing SPARTAN Study evaluating the potential effect of FILSPARI as a first-line therapy in patients with newly diagnosed IgAN.In 2024, the Company anticipates inclusion of FILSPARI into the Kidney Disease Improving Global Outcomes (KDIGO) Clinical Practice Guideline for the Management of Glomerular Diseases. Sparsentan – Focal Segmental Glomerulosclerosis (FSGS) In 2024, the Company is conducting additional analyses of FSGS data and will engage with regulators to evaluate potential regulatory pathways for a sparsentan FSGS indication. Pegtibatinase – Classical HCU In December 2023, the Company initiated the pivotal Phase 3 HARMONY Study to support the potential approval of pegtibatinase for the treatment of HCU. The HARMONY Study is a global, randomized, multi-center, double-blind, placebo-controlled Phase 3 clinical trial designed to evaluate the efficacy and safety of pegtibatinase as a novel treatment to reduce total homocysteine (tHcy) levels. The trial is expected to enroll approximately 70 patients with a diagnosis of classical HCU and tHcy levels ≥50 μM while maintaining their standard-of-care treatment. The primary endpoint is relative geometric mean change in plasma tHcy levels from baseline compared to weeks 6 through 12. Durability of treatment response through 24 weeks of treatment will also be measured as a secondary endpoint. Topline results from the HARMONY Study are expected in 2026.The Company will also be initiating the ENSEMBLE Study, a Phase 3b, open-label, long-term extension, that will evaluate the ongoing efficacy and long-term safety of pegtibatinase in participants with HCU following their completion of the Phase 1/2 COMPOSE Study or the HARMONY Study. ENSEMBLE will include an optional protein tolerance modification sub-study that will evaluate if patients can increase their natural dietary protein intake and maintain an acceptable level of metabolic control while receiving pegtibatinase.

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. Embryo-Fetal Toxicity: FILSPARI can cause fetal harm. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test and advise patients who can become pregnant to use effective contraception prior to, during, and one month after discontinuation of FILSPARI treatment.FILSPARI REMS: FILSPARI is available only through a restricted program under a REMS called the FILSPARI REMS.Important requirements include: Prescribers must be certified with the FILSPARI REMS by enrolling and completing training.All patients must enroll in the FILSPARI REMS prior to initiating treatment and comply with monitoring requirements.Pharmacies that dispense FILSPARI must be certified with the FILSPARI REMS and must dispense only to patients who are authorized to receive FILSPARI.

Received 459 new patient start forms for FILSPARI® (sparsentan) in the fourth quarter of 2023; preliminary net product sales of FILSPARI totaled $15 million for the fourth quarter Company on track to submit sNDA to FDA in Q1 2024 for conversion of the existing U.S. accelerated approval of FILSPARI in IgAN to full approval CHMP opinion on potential approval of sparsentan for the treatment of IgAN in Europe expected in Q1 2024 Pivotal Phase 3 study of pegtibatinase in classical homocystinuria (HCU) underway SAN DIEGO, Jan. 08, 2024 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc. (NASDAQ: TVTX) today announced that, based on preliminary and unaudited financial data, the Company expects net product sales from continuing operations for the fourth quarter of 2023 to be approximately $40 million. For the fiscal year 2023, the Company expects net product sales from continuing operations to be approximately $128 million. The Company ended 2023 with approximately $567 million in cash, cash equivalents, and marketable securities which is expected to support operations into 2028. The Company also provided an update on key corporate, clinical, and regulatory development initiatives, including anticipated milestones for 2024. "Our strong fourth quarter results reflect the growing demand for FILSPARI in IgAN driven by our field teams’ education and outreach efforts to healthcare providers,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “In 2024, we are well-positioned to drive sustained growth of FILSPARI as the only non-immunosuppressive therapy for IgAN through our continued strong commercial execution and the potential conversion from accelerated to full approval. Additionally, we are pleased to have recently initiated the pivotal HARMONY Study for pegtibatinase. We are focused on building momentum for enrollment of this important trial which is designed to support the potential approval of pegtibatinase as the first and only disease-modifying therapy for classical HCU. Looking forward, we believe our efforts will ultimately position FILSPARI and pegtibatinase as new treatment standards in IgAN and classical HCU, clearly helping to address the needs of patients living with these rare diseases.” Program Updates and Anticipated 2024 Milestones FILSPARI (sparsentan) 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. In 2024, the Company anticipates conversion of FILSPARI from accelerated approval to full approval for IgAN as well as a potential approval for the treatment of IgAN in Europe. The Company is also generating additional data that is expected to support the clinical profile of FILSPARI and it anticipates updates to treatment guidelines for IgAN to include FILSPARI. FILSPARI (sparsentan) – IgAN In the fourth quarter of 2023, the Company received 459 new patient start forms (PSFs), reflecting continued strength in physician demand. Preliminary net product sales of FILSPARI in the fourth quarter of 2023 were $15 million; $30 million since the beginning of commercial launch in February 2023. The Company is on track to submit a supplemental New Drug Application (sNDA) in the first quarter of 2024 for conversion of the existing U.S. accelerated approval of FILSPARI to full approval. Following submission of the two-year results from the PROTECT Study of FILSPARI in IgAN and a corresponding procedural review clock-stop, the Company and its collaborator CSL Vifor anticipate a review opinion by the Committee for Medicinal Products for Human Use (CHMP) on the potential approval of the Conditional Marketing Authorization (CMA) application for sparsentan for the treatment of IgAN in Europe in the first quarter of 2024. If approved, sparsentan would receive CMA in all member states of the European Union, as well as in Iceland, Liechtenstein, and Norway. In 2024, the Company expects additional data from its ongoing open-label studies evaluating the safety and efficacy of sparsentan in combination with sodium glucose cotransporter-2 inhibitors (SGLT2i) as well as from the ongoing SPARTAN Study evaluating the potential effect of FILSPARI as a first-line therapy in patients with newly diagnosed IgAN. In 2024, the Company anticipates inclusion of FILSPARI into the Kidney Disease Improving Global Outcomes (KDIGO) Clinical Practice Guideline for the Management of Glomerular Diseases. Sparsentan – Focal Segmental Glomerulosclerosis (FSGS) In 2024, the Company is conducting additional analyses of FSGS data and will engage with regulators to evaluate potential regulatory pathways for a sparsentan FSGS indication. Pegtibatinase – Classical HCU The Company is advancing pegtibatinase, a novel investigational enzyme replacement therapy with the potential to become the first and only disease-modifying therapy for people living with classical homocystinuria (HCU). In December 2023, the Company initiated the pivotal Phase 3 HARMONY Study to support the potential approval of pegtibatinase for the treatment of classical HCU. The HARMONY Study is a global, randomized, multi-center, double-blind, placebo-controlled Phase 3 clinical trial designed to evaluate the efficacy and safety of pegtibatinase as a novel treatment to reduce total homocysteine (tHcy) levels. The trial is expected to enroll approximately 70 patients with a diagnosis of classical HCU and tHcy levels ≥50 μM while maintaining their standard-of-care treatment. Participants will be randomized 1:1 to receive 2.5 mg/kg of pegtibatinase or placebo, administered subcutaneously, for a 24-week blinded treatment duration. The primary endpoint is relative geometric mean change in plasma tHcy levels from baseline compared to weeks 6 through 12. Durability of treatment response through 24 weeks of treatment will also be measured as a secondary endpoint. Topline results from the HARMONY Study are expected in 2026. The Company will also be initiating the ENSEMBLE Study, a Phase 3b, open-label, long-term extension, that will evaluate the ongoing efficacy and long-term safety of pegtibatinase in participants with HCU following their completion of the COMPOSE Study or the HARMONY Study. ENSEMBLE will include an optional protein tolerance modification sub-study that will evaluate if patients can increase their natural dietary protein intake and maintain an acceptable level of metabolic control while receiving pegtibatinase. The Company expects to announce complete full year 2023 financial results and provide a corporate update in February.

For more information, visit travere.com About FILSPARI (sparsentan) FILSPARI (sparsentan) is a once-daily, oral medication designed to selectively target two critical pathways in the disease progression of IgAN (endothelin-1 and angiotensin II) and is the first and only non-immunosuppressive therapy approved for the treatment of this condition. FILSPARI is a prescription medicine indicated to reduce proteinuria in adults with primary IgAN at risk of rapid disease progression, generally a UPCR ≥1.5 g/g. FILSPARI (sparsentan) U.S. 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 TOXICITYBecause 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. HepatotoxicitySome 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 Upper Limit of Normal (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), endothelin receptor antagonists (ERAs), or aliskiren. Warnings and Precautions Hepatotoxicity: Hepatotoxicity: Elevations in ALT or AST of at least 3-fold ULN have been observed. To reduce the risk of potential serious hepatotoxicity, measure serum aminotransferase levels and total bilirubin prior to initiation of treatment, 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. Embryo-Fetal Toxicity: FILSPARI can cause fetal harm. Advise patients who can become pregnant of the potential risk to a fetus. Obtain a pregnancy test and advise patients who can become pregnant to use effective contraception prior to, during, and one month after discontinuation of FILSPARI treatment.FILSPARI REMS: FILSPARI is available only through a restricted program under a REMS called the FILSPARI REMS.Important requirements include: Prescribers must be certified with the FILSPARI REMS by enrolling and completing training.All patients must enroll in the FILSPARI REMS prior to initiating treatment and comply with monitoring requirements.Pharmacies that dispense FILSPARI must be certified with the FILSPARI REMS and must dispense only to patients who are authorized to receive FILSPARI.
