SAN DIEGO, Oct. 31, 2024 (GLOBE NEWSWIRE) -- Travere Therapeutics, Inc., (NASDAQ: TVTX) today reported its third quarter 2024 financial results and provided a corporate update.

“Our performance in the third quarter was exceptional. FILSPARI received full approval as the only medicine that can provide superior preservation of kidney function and replace current standard of care in IgAN, and our commercial team delivered strong growth in sales of FILSPARI in the U.S. Additionally, I am pleased to report that in the weeks since full approval we have seen a meaningful increase in demand, supporting our expectation that the broader label granted upon full approval coupled with the recent draft KDIGO guidelines will strengthen FILSPARI’s growth,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “As we look ahead, we are very well-positioned to further accelerate our growth with FILSPARI. At ASN Kidney Week, we illustrated the potential benefits of using FILSPARI as a first-line treatment, and presented data in combination with other therapies. Our European partner CSL Vifor has launched FILSPARI commercially in the first EU countries. And following the recent PARASOL group recommendation of a proteinuria-based clinical trial endpoint for FSGS, we have scheduled a meeting with the FDA to discuss a potential path forward for FILSPARI in FSGS.”

Financial Results for Continuing Operations for the Quarter Ended September 30, 2024

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 third quarter of 2024 were $61.0 million, compared to $33.9 million for the same period in 2023. The increase is attributable to sales from the ongoing commercial launch of FILSPARI.

Research and development (R&D) expenses for the third quarter of 2024 were $51.7 million, compared to $60.6 million for the same period in 2023. For the nine months ended September 30, 2024, R&D expenses were $155.4 million, compared to $185.2 million for the same period in 2023. The decrease is largely attributable to previously announced restructuring initiatives and a decline in costs associated with the development of sparsentan as the Phase 3 programs advance towards completion. On a non-GAAP adjusted basis, R&D expenses were $48.4 million for the third quarter of 2024, compared to $53.8 million for the same period in 2023.

Selling, general, and administrative (SG&A) expenses for the third quarter of 2024 were $65.6 million, compared to $67.8 million for the same period in 2023. For the nine months ended September 30, 2024, SG&A expenses were $194.6 million, compared to $202.0 million for the same period in 2023. The decrease is primarily driven by the previously announced restructuring and other cost saving initiatives. On a non-GAAP adjusted basis, SG&A expenses were $49.7 million for the third quarter of 2024, compared to $51.8 million for the same period in 2023.

Total other income, net, for the third quarter of 2024 was $1.3 million, compared to total other income, net, of $3.4 million for the same period in 2023. The difference is largely attributable to a decrease in interest income during the period.

Net loss including discontinued operations for the third quarter of 2024 was $54.8 million, or $0.70 per basic share, compared to a net income of $150.7 million, or $1.97 per basic share for the same period in 2023. For the nine months ended September 30, 2024, net loss including discontinued operations was $261.3 million, compared to $21.2 million for the same period in 2023. On a non-GAAP adjusted basis, net loss including discontinued operations for the third quarter of 2024 was $35.6 million, or $0.46 per basic share, compared to a net income of $173.5 million, or $2.27 per basic share for the same period in 2023.

As of September 30, 2024, the Company had cash, cash equivalents, and marketable securities of $277.4 million.

Program Updates

FILSPARI^® (sparsentan) – IgA Nephropathy (IgAN)

• On September 5, 2024, the U.S. Food and Drug Administration (FDA) granted full approval to FILSPARI to slow kidney function decline in adults with primary IgAN who are at risk of disease progression. The expanded indication made FILSPARI available to patients with IgAN at risk of progression and the updated label includes data showing superior long-term durable benefit on proteinuria and kidney function preservation that accrued over two years when compared to 300 mg of the active comparator irbesartan.
  
• Commercial progress in the ongoing launch has resulted in:
  
  • 505 new patient start forms (PSFs) received in the third quarter of 2024; a total of 2,989 PSFs have been received since launch in February of 2023.
  • Net product sales of $35.6 million for the third quarter; year-to-date FILSPARI net product sales total $82.6 million.
• The Company has submitted a supplemental New Drug Application (sNDA) requesting a modification to the frequency of liver monitoring for FILSPARI.
  
• In connection with full approval and an expanded indication, the FDA granted an additional term of Orphan Drug Exclusivity for FILSPARI in IgAN expiring in September 2031.
  
• In August 2024, Kidney Disease Improving Global Outcomes (KDIGO) published its draft guidelines for IgAN, recommending FILSPARI as a foundational kidney-targeted therapy and lowering the targeted proteinuria level for all IgAN patients to under 0.5 g/day or ideally complete remission (under 0.3 g/day).
  
• At ASN Kidney Week (October 23 – 27), the Company presented 9 abstracts on FILSPARI in IgAN, including:
  
  • An analysis from the PROTECT Study examining the clinical benefit of FILSPARI in IgAN regardless of participants’ baseline proteinuria demonstrating that treatment with FILSPARI reduced proteinuria and preserved kidney function in patients with lower ranges of proteinuria (<1.0 g/g); and patient-reported outcomes from PROTECT suggesting that patients receiving FILSPARI had less burden of kidney disease over time and trend toward improved health-related quality of life compared with maximally dosed irbesartan.
  • Data from a pre-specified interim analysis of the SPARTAN Study demonstrating that as a first-line treatment in patients newly diagnosed with IgAN, FILSPARI delivered a rapid and sustained reduction in proteinuria of approximately 70% from baseline over 24 weeks and was generally well tolerated. In addition, nearly 60% of patients achieved complete remission at any point of time during the treatment period. Throughout the 24 weeks, estimated glomerular filtration rate was stable.
  • Interim data from the SPARTACUS Study demonstrating that FILSPARI when added to stable SGLT2 inhibitors was generally well tolerated and at 24 weeks approximately one-third of patients had their proteinuria reduced by at least 50% after the addition of FILSPARI. The Company also presented new combination data from the ongoing PROTECT open label extension, and real-world clinical experience of FILSPARI in IgAN demonstrating FILSPARI induced further proteinuria reduction and showed favorable safety and additive efficacy results when used in combination with SGLT2 inhibitors or steroids.
• In the third quarter, the Company’s commercial partner CSL Vifor launched FILSPARI in Germany and Austria, and recently received temporary marketing approval in Switzerland.
  

Sparsentan – Focal Segmental Glomerulosclerosis (FSGS)

• The Company has scheduled a Type C meeting with FDA to discuss a potential regulatory pathway for a sparsentan FSGS indication. The Company expects to provide an update on the FSGS program by its fourth quarter 2024 earnings call.
  
• At ASN Kidney Week 2024, the Company presented two abstracts illustrating the potential benefit of sparsentan in patients with FSGS.
  
  • A late-breaking presentation in patients with genetic FSGS, a small subgroup of patients that are often resistant to treatment, with results that demonstrated a rapid and sustained proteinuria reduction, including some patients who achieved complete remission and long-term kidney health benefits.
  • Patient-reported outcomes from the DUPLEX Study suggesting health-related quality of life with sparsentan was stable over the two-year treatment period.

Pegtibatinase (TVT-058) – Classical Homocystinuria (HCU)

• In September 2024, the Company announced a voluntary pause of enrollment in the Phase 3 HARMONY Study of pegtibatinase to allow for necessary process improvements in manufacturing scale-up to support commercial scale manufacturing as well as full enrollment in the HARMONY Study.
  
• Currently enrolled patients will be able to continue uninterrupted on study medication for the duration of the trials they are participating in.
  
• The Company expects to further evaluate the necessary commercial process improvements to enable the continuation of the Phase 3 program and anticipates the earliest date to restart enrollment in the Phase 3 HARMONY Study will be in 2026.

Use of Non-GAAP Financial Measures

To supplement Travere’s financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses certain non-GAAP adjusted financial measures in this press release and the accompanying tables. The Company believes that these non-GAAP financial measures are helpful in understanding its past financial performance and potential future results. They are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with the consolidated financial statements prepared in accordance with GAAP. Travere’s management regularly uses these supplemental non-GAAP financial measures internally to understand, manage and evaluate its business and make operating decisions. In addition, Travere believes that the use of these non-GAAP measures enhances the ability of investors to compare its results from period to period and allows for greater transparency with respect to key financial metrics the Company uses in making operating decisions.

Investors should note that these non-GAAP financial measures are not prepared under any comprehensive set of accounting rules or principles and do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP.

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.
