Business Overview and History
Travere Therapeutics, Inc. (TVTX) is a biopharmaceutical company laser-focused on identifying, developing, and delivering life-changing therapies for people living with rare kidney and metabolic diseases. With a strategic vision and a steadfast commitment to addressing unmet medical needs, Travere has positioned itself as a pioneer in the rare disease landscape.
Travere Therapeutics was founded in 2011 and is headquartered in San Diego, California. In 2014, the company entered into a license agreement with Mission Pharmacal to obtain an exclusive, royalty-bearing license to market, sell and commercialize Thiola, a treatment for cystinuria, in the United States and Canada. This marked Travere's first approved product and entry into the rare disease market.
A significant milestone in Travere's history occurred in 2012 when the company entered into an agreement with Ligand Pharmaceuticals for a worldwide sublicense to develop, manufacture and commercialize sparsentan, which would later become the company's lead product candidate. Over the subsequent years, Travere conducted extensive clinical trials for sparsentan in two rare kidney diseases - IgA nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS).
In 2020, Travere made a strategic move by acquiring Orphan Technologies Limited, which brought the rare metabolic disorder drug pegtibatinase into its pipeline. This acquisition further strengthened the company's focus on developing innovative therapies for underserved patient populations. Around the same time, Travere entered into a license and collaboration agreement with Vifor International Ltd. for the commercialization of sparsentan in Europe, Australia and New Zealand, expanding its global reach.
Throughout its history, Travere has faced various challenges, including the need to raise additional capital through equity offerings to fund its research and development activities. The company also experienced setbacks, such as the failure of its Phase 3 DUPLEX study of sparsentan in FSGS to meet its primary endpoint. However, Travere's perseverance and commitment to its mission have allowed it to continue advancing its programs and exploring strategic partnerships to enhance its capabilities and market presence.
In September 2024, Travere achieved a significant milestone with the full FDA approval of FILSPARI (sparsentan) for the treatment of IgA nephropathy (IgAN), a rare and progressive kidney disease. FILSPARI's approval marked the culmination of Travere's diligent efforts, as it became the first non-immunosuppressive therapy approved for IgAN and the only oral, once-daily treatment that directly targets the underlying causes of the disease.
Travere's pipeline extends beyond FILSPARI, with the company actively advancing its investigational therapy, pegtibatinase, for the treatment of classical homocystinuria (HCU), a rare genetic disorder. Pegtibatinase has been granted Rare Pediatric Disease, Fast Track, and Breakthrough Therapy designations by the FDA, underscoring its potential to become the first disease-modifying treatment for HCU patients.

Travere's return on assets (ROA) and return on equity (ROE) for 2024 were -54.12% and -10.91%, respectively, underscoring the capital-intensive nature of the company's business and the ongoing investments required to advance its pipeline.
For the most recent quarter ended December 31, 2024, Travere reported revenue of $74.78 million and a net loss of $60.26 million. The company's cash and cash equivalents stood at $58.53 million as of December 31, 2024. Travere's annual operating cash flow for 2024 was -$230.02 million, while its annual free cash flow was -$338.69 million.
The company's quick ratio, which measures its ability to meet short-term obligations with its most liquid assets, was 2.04 as of December 31, 2024, further indicating a strong liquidity position.
Product Portfolio and Pipeline
Travere's product portfolio and pipeline are centered around two key segments: approved products and clinical-stage programs.
Approved Products:
1. FILSPARI (sparsentan): FILSPARI is Travere's lead approved product, granted full approval by the FDA in September 2024 to slow kidney function decline in adults with primary Immunoglobulin A nephropathy (IgAN) who are at risk of disease progression. It is the only oral, once-daily, non-immunosuppressive medication that directly targets glomerular injury in the kidney by blocking two critical pathways of IgAN disease progression - endothelin-1 and angiotensin II.
The full approval was based on positive long-term confirmatory results from the PROTECT Study, which demonstrated that FILSPARI significantly slowed kidney function decline over two years compared to the active control, irbesartan. In the final analysis of the 404 randomized patients, FILSPARI showed a statistically significant treatment effect, reducing the rate of decline in kidney function from baseline to Week 110 by 1.20 mL/min/1.73m2 per year compared to irbesartan.
Travere has granted an exclusive license to CSL Vifor for the commercialization of FILSPARI in Europe, Australia, and New Zealand. FILSPARI became commercially available in Europe under a conditional marketing authorization in August 2024, with an initial launch in Germany and Austria. Travere also entered into an exclusive licensing agreement with Renalys Pharma, Inc. to bring FILSPARI to patients in Japan and other countries in Asia.
2. Thiola and Thiola EC (tiopronin): These products are approved in the United States for the prevention of cystine kidney stone formation in patients with severe homozygous cystinuria. While Thiola has faced generic competition, with a generic option for the 100mg version of the original formulation approved in 2021 and a second 100mg generic option approved in 2022, as of December 31, 2024, several generic options for both the 100mg and 300mg versions of Thiola EC have also been approved by the FDA and become available, subjecting Thiola EC to generic competition as well.
Clinical-Stage Programs:
1. Sparsentan for the treatment of Focal Segmental Glomerulosclerosis (FSGS): Sparsentan has been granted Orphan Drug Designation for the treatment of FSGS in the U.S. and Europe. In the Phase 3 DUPLEX Study, sparsentan did not achieve its two-year primary endpoint of rate of change in eGFR with statistical significance over the active control, irbesartan. However, the study results showed favorable trends, including a pre-specified secondary endpoint on proteinuria reduction.
2. Pegtibatinase for the treatment of Classical Homocystinuria (HCU): Pegtibatinase is a novel investigational human enzyme replacement candidate being evaluated for the treatment of classical HCU. It has been granted Rare Pediatric Disease, Fast Track, and Breakthrough Therapy designations by the FDA, as well as orphan drug designation in the U.S. and EU. In December 2023, Travere initiated the pivotal Phase 3 HARMONY Study to support the potential approval of pegtibatinase as the first disease-modifying treatment for HCU. However, in September 2024, Travere announced a voluntary pause of enrollment in the HARMONY Study to address necessary process improvements in manufacturing scale-up to support commercial scale manufacturing and full enrollment in the study.
Pipeline Progression and Regulatory Milestones
Travere's pipeline progress has been a key driver of the company's growth and investor interest. In addition to the full approval of FILSPARI for IgAN, the company has made significant strides in advancing its other late-stage programs.
In February 2025, Travere announced that it had completed a Type C meeting with the FDA and plans to submit a supplemental New Drug Application (sNDA) around the end of the first quarter of 2025, seeking traditional approval of FILSPARI for the treatment of focal segmental glomerulosclerosis (FSGS), a rare and progressive kidney disorder. If approved, FILSPARI could become the first and only FDA-approved therapy for FSGS, a disease with significant unmet medical need.
Regarding pegtibatinase, Travere's investigational enzyme replacement therapy for the treatment of classical HCU, the company is making progress on the necessary manufacturing scale-up and process improvements to enable the reopening of enrollment in the pivotal Phase 3 HARMONY study. The company anticipates restarting the HARMONY study in 2026, keeping the program on track to potentially become the first disease-modifying therapy for HCU patients.
Competitive Landscape and Market Opportunity
The rare disease space in which Travere operates is highly competitive, with both established players and emerging biotechnology companies vying for market share. However, Travere's unique product profiles and strategic partnerships have positioned the company as a formidable contender.
In the IgAN market, FILSPARI faces competition from recently approved therapies, such as Fabhalta (iptacopan) from Novartis and atrasentan from an undisclosed competitor. Nonetheless, FILSPARI's demonstrated superiority over the historical standard of care in clinical trials, its flexible dosing, and its foundational positioning as a non-immunosuppressive, kidney-targeted therapy have bolstered its competitive advantages.
In the FSGS landscape, if approved, FILSPARI would be the first and only FDA-approved therapy for this rare and debilitating kidney disorder. Travere estimates that there are more than 40,000 FSGS patients in the United States, representing a significant market opportunity for the company.
Regarding HCU, Travere's pegtibatinase has the potential to become the first disease-modifying therapy for this rare metabolic condition, which affects approximately 7,000 to 10,000 patients globally. The company's strategic partnerships and designations, such as Rare Pediatric Disease and Breakthrough Therapy, underscore the unmet need and the promise of pegtibatinase in this underserved patient population.
Financial Performance and Outlook
Travere's financial performance has been driven by the launch and commercialization of FILSPARI, as well as continued sales of its tiopronin products, Thiola and Thiola EC. For the year ended December 31, 2024, Travere reported total revenue of $233.18 million, including $226.71 million in net product sales. This represents a significant increase from the prior year, as FILSPARI generated $132.22 million in net sales in 2024, its first full year on the market. Sales of the tiopronin products, Thiola and Thiola EC, contributed $94.48 million in net sales. While the tiopronin products have faced generic competition, they continue to generate meaningful revenue for the company.
Travere's research and development expenses totaled $217.50 million in 2024, reflecting investments in the advancement of its clinical-stage pipeline, including the sparsentan and pegtibatinase programs. The company also incurred $264.12 million in selling, general, and administrative expenses, primarily driven by the commercial launch and support of FILSPARI.
Looking ahead, Travere expects a moderate increase in gross to net discounts for FILSPARI in 2025 compared to 2024 but believes net product sales of FILSPARI in IgA nephropathy will grow significantly in 2025 and continue to outpace benchmark launches. The company anticipates receiving milestone payments from CSL Vifor upon conversion of FILSPARI to full approval in Europe and achieving market access milestones later in 2025. Travere projects that their operating cash use will continue to decline over time and that their balance sheet will be able to support their key priorities to advance their growth.
Risks and Challenges
As with any biopharmaceutical company, Travere faces a variety of risks and challenges that could impact its long-term success. These include the inherent uncertainties of the drug development and regulatory approval process, potential competition from new market entrants, and the company's ability to effectively scale its manufacturing and commercial operations to meet growing demand.
Additionally, Travere's heavy reliance on the success of its lead assets, FILSPARI and pegtibatinase, exposes the company to concentration risk. Any setbacks or delays in the development or commercialization of these programs could have a significant impact on Travere's financial performance and investor sentiment.
The company also faces the challenge of navigating complex regulatory environments, both domestically and internationally, as it seeks to expand the reach of its approved and investigational therapies. Unfavorable pricing and reimbursement decisions by government and private payers could also limit the commercial potential of Travere's products.
