“2022 was a foundational year for Travere. We demonstrated clinical expertise with the advancement of our development programs, reached new patients with our approved products, and prepared our organization for a new phase of growth to deliver new medicines to rare disease patients,” said Eric Dube, Ph.D., chief executive officer of Travere Therapeutics. “Most importantly, our accomplishments in 2022 led to the recent accelerated approval of FILSPARI for the reduction of proteinuria in patients with IgAN, the first FDA approval from our development pipeline of therapies targeting rare diseases with limited or no treatment options. Our teams began calling on prescribers on February 20^th and we are pleased with the early reception to education on FILSPARI’s superior proteinuria reduction compared to irbesartan and its well-defined safety profile. In addition to remaining focused on a successful U.S. launch of FILSPARI in 2023, we are continuing to advance our programs with a number of exciting milestones ahead. In the second quarter, we look forward to two-year data from the ongoing DUPLEX Study of sparsentan in FSGS, and later in the year we expect a review decision on the CMA application for sparsentan for the treatment of IgAN in Europe. We also anticipate additional data from our novel pegtibatinase program for HCU and the potential initiation of a Phase 3 program this year. We take great pride in our progress to date and are honored to provide life-changing treatments to patients with rare disease.”

Fourth Quarter and Full Year 2022 Financial Results

Net product sales for the fourth quarter of 2022 were $52.3 million, compared to $54.6 million for the same period in 2021. For the full year 2022, net product sales were $200.5 million, compared to $210.8 million for the same period in 2021. The difference is largely attributable to a decrease in Thiola sales partially offset by an increase in sales of the Company’s bile acid products.

Research and development (R&D) expenses for the fourth quarter of 2022 were $60.2 million, compared to $62.2 million for the same period in 2021. For the full year 2022, R&D expenses were $235.8 million, compared to $210.3 million for the same period in 2021. The difference is largely attributable to the continued advancement of the Company’s sparsentan and pegtibatinase clinical programs, including clinical trial expenses, manufacturing and increased headcount. On a non-GAAP adjusted basis, R&D expenses were $54.2 million for the fourth quarter of 2022, compared to $57.7 million for the same period in 2021.

Selling, general and administrative (SG&A) expenses for the fourth quarter of 2022 were $62.9 million, compared to $42.1 million for the same period in 2021. For the full year 2022, SG&A expenses were $220.2 million, compared to $149.9 million for the same period in 2021. The difference is largely attributable to commercial launch preparations for FILSPARI, including additional field-based headcount. On a non-GAAP adjusted basis, SG&A expenses were $50.2 million for the fourth quarter of 2022, compared to $ 30.9 million for the same period in 2021.

Total other income, net, for the fourth quarter of 2022 was $1.1 million, compared to total other expense, net, of $4.4 million for the same period in 2021. The difference is largely attributable to increased interest income and lower interest expense during the period.

Net loss for the fourth quarter of 2022 was $65.8 million, or $1.03 per basic share, compared to a net loss of $51.6 million, or $0.84 per basic share for the same period in 2021. For the full year 2022, net loss was $278.5 million, compared to $180.1 million for the same period in 2021. On a non-GAAP adjusted basis, net loss for the fourth quarter of 2022 was $49.1 million, or $0.76 per basic share, compared to a net loss of $37.6 million, or $0.61 per basic share for the same period in 2021.

As of December 31, 2022, the Company had cash, cash equivalents and marketable securities of $450.2 million.

Program Updates

FILSPARI™ (sparsentan) – IgAN

• On February 17, 2023, the U.S. 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. The approval of FILSPARI is based on clinically meaningful and statistically significant improvements in proteinuria compared to irbesartan, an active comparator, in the pivotal and ongoing Phase 3 PROTECT Study, the largest head-to-head interventional study to date in IgAN.
   
• FILSPARI is expected to be commercially available beginning the week of February 27, 2023. The Company has launched Travere TotalCare™ to provide a comprehensive patient support program to enable a smooth experience for patients, their caregivers and healthcare providers. This program provides services, assistance and resources that will help patients understand IgAN, manage the insurance process, fill their prescriptions and initiate treatment.
   
• In the second half of 2023, the Company together with its collaborator CSL Vifor, anticipates a review decision by the EMA on the potential approval of the CMA application for sparsentan for the treatment of IgAN in Europe. If approved, sparsentan would receive CMA in all member states of the European Union, as well as in Iceland, Liechtenstein and Norway.
   
• In the fourth quarter of 2023, the Company expects to report topline results from the two-year confirmatory endpoints in the ongoing Phase 3 PROTECT Study, which are designed to support traditional approval of sparsentan in IgAN.
   
• Beginning in 2023, the Company plans to expand data generation through a sub study in the open-label extension of the ongoing PROTECT Study, as well as an open-label clinical study to investigate the safety and efficacy of sparsentan in combination with sodium glucose cotransporter-2 inhibitors (SGLT2i) for the treatment of IgAN.

Sparsentan - FSGS

• In February 2021, the Company announced that the ongoing pivotal Phase 3 DUPLEX Study of sparsentan in FSGS achieved its pre-specified interim FSGS partial remission of proteinuria endpoint (FPRE) with statistical significance. FPRE is a clinically meaningful endpoint defined as urine protein-to-creatinine ratio (UP/C) ≤1.5 g/g and a >40 percent reduction in UP/C from baseline. After 36 weeks of treatment, 42.0 percent of patients receiving sparsentan achieved FPRE, compared to 26.0 percent of irbesartan-treated patients (p=0.0094). Preliminary results at the time of the interim assessment suggested that sparsentan had been generally well-tolerated and showed a comparable safety profile to irbesartan. The DUPLEX Study is fully enrolled and scheduled to continue as planned on a blinded basis to assess the confirmatory eGFR endpoint after 108 weeks of treatment.
   
• In the second quarter of 2023, the Company expects to report topline results from the two-year confirmatory endpoints in the ongoing Phase 3 DUPLEX Study of sparsentan in FSGS. Pending data supportive of approval, the Company anticipates submitting a supplemental New Drug Application (sNDA) for traditional approval for FSGS in the second half of 2023.
   
• Pending completion of the DUPLEX Study of sparsentan in FSGS and data supportive of approval, a subsequent variation to the CMA of sparsentan for the treatment of FSGS in Europe is targeted for submission by the end of 2023.

Pegtibatinase (TVT-058) – HCU

The Company continues to advance pegtibatinase, a novel investigational enzyme replacement therapy with the potential to become the first disease-modifying therapy for people living with classical homocystinuria (HCU). Following positive results from the first five cohorts of the ongoing Phase 1/2 COMPOSE Study, the Company is evaluating pegtibatinase in a final cohort in the COMPOSE Study to further inform its potential pivotal development program.

• In the fourth quarter of 2022, enrollment completed in the sixth and final cohort of the ongoing Phase 1/2 COMPOSE Study. The Company anticipates reporting additional data from COMPOSE in mid-2023.
   
• In parallel with completing the final cohort in the COMPOSE Study, the Company is preparing for the potential initiation of a pivotal Phase 3 clinical trial of pegtibatinase in patients with HCU in the second half of 2023.

CDCA – CTX

The Company’s chenodeoxycholic acid (CDCA) program includes Chenodal (chenodiol), a commercially available product that is under clinical evaluation to include an indication for cerebrotendinous xanthomatosis (CTX), a rare, progressive, and underdiagnosed bile acid synthesis disorder, to its label.

• During 2023, the Company expects to complete the ongoing Phase 3 RESTORE Study in CTX. Pending supportive data, the Company anticipates being in position to subsequently submit an NDA for a CTX indication.

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. Investors should also note that these non-GAAP financial measures have no standardized meaning prescribed by GAAP and, therefore, have limits in their usefulness to investors. In addition, from time to time in the future the Company may exclude other items, or cease to exclude items that it has historically excluded, for purposes of its non-GAAP financial measures; because of the non-standardized definitions, the non-GAAP financial measures as used by the Company in this press release and the accompanying tables may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by the Company’s competitors and other companies.

As used in this press release, (i) the historical non-GAAP net loss measures exclude from GAAP net loss, as applicable, stock-based compensation expense, amortization and depreciation expense, revaluation of business combination related contingent consideration and income tax; (ii) the historical non-GAAP SG&A expense measures exclude from GAAP SG&A expenses, as applicable, stock-based compensation expense, and amortization and depreciation expense; (iii) the historical non-GAAP R&D expense measures exclude from GAAP R&D expenses, as applicable, stock-based compensation expense, and amortization and depreciation expense.

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 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 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.

Further information is available at www.filsparirems.com or 1-833-513-1325.
