Previous wording

On September 5, 2024, the FDA granted full approval of FILSPARI® (sparsentan) to slow kidney function decline in adults with primary Immunoglobulin A nephropathy (IgAN) who are at risk of disease progression. FILSPARI had previously been granted accelerated approval in February 2023 based on the surrogate marker of proteinuria. Full approval is based on positive long-term confirmatory results from the PROTECT Study demonstrating that FILSPARI significantly slowed kidney function decline over two years compared to irbesartan. FILSPARI initially became commercially available in the U.S. in February 2023 under accelerated approval, and we are providing a comprehensive patient support program throughout the patient’s treatment journey.

Previous wording

The two-year efficacy data contained in the FDA-approved label is a modified intention to treat (ITT) analysis, and as preferred by the FDA, evaluates data from all patients regardless of treatment discontinuation. In the final analysis of the 404 randomized patients, FILSPARI significantly reduced the rate of decline in kidney function from baseline to Week 110 compared to irbesartan. In the ITT analysis included in the label, the mean eGFR slope from baseline to Week 110 was -3.0 mL/min/1.73 m 2/year for FILSPARI and -4.2 mL/min/1.73 m 2/year for irbesartan, corresponding to a statistically significant treatment effect of 1.2 mL/ min/1.73 m 2/year (p=0.0168). The positive treatment effects on proteinuria compared to the active control irbesartan that were observed at Week 36 were durable out to the two-year measurement period. Additional results from the PROTECT Study demonstrated the benefit of FILSPARI on absolute eGFR accrued over time and by Week 110 resulted in a 3.8 mL/min/1.73 m 2 difference in the mean change from baseline between FILSPARI and irbesartan.

Previous wording

FILSPARI is a dual endothelin angiotensin receptor antagonist (DEARA). Pre-clinical data have shown that blockade of both endothelin type A and angiotensin II type 1 pathways in forms of rare chronic kidney disease, reduces proteinuria, protects podocytes and prevents glomerulosclerosis and mesangial cell proliferation. Sparsentan has been granted Orphan Drug Designation for the treatment of IgAN in the U.S. and the European Economic Area countries (the “EEA”) and FILSPARI has been granted seven years of Orphan Drug Exclusivity in the U.S. (running from the date of accelerated approval) for the reduction of proteinuria in adults with primary IgAN at risk of rapid disease progression, and has been granted a separate seven years of Orphan Drug Exclusivity in the U.S. (running from the date of full approval) to slow kidney function decline in adults with primary IgAN who are at risk for disease progression, excluding the use provided for in the aforementioned Orphan Drug Exclusivity granted in connection with the accelerated approval.

Previous wording

IgAN is characterized by hematuria, proteinuria, and variable rates of progressive renal failure. With an estimated prevalence of up to 150,000 people in the United States and greater numbers in Europe and Asia, IgAN is the most common primary glomerular disease. Most patients are diagnosed between the ages of 16 and 35, with up to 40% progressing to kidney failure within 15 years. FILSPARI is the first and only oral, once-daily, non-immunosuppressive therapy approved for this condition that directly targets glomerular injury in the kidney by blocking two critical pathways of IgAN disease progression (endothelin-1 and angiotensin II). We estimate over 70,000 patients in the United States to be addressable under FILSPARI's full approval indication.

FILSPARI is available only through a risk evaluation and mitigation strategy (REMS) approved by the FDA, regarding mandatory birth control for patients of child-bearing potential regarding risk of embryo-fetal toxicity, as has been required for other approved endothelin antagonists, and a REMS for liver monitoring regarding potential risk of hepatotoxicity, as has been required for certain other approved endothelin antagonists. As part of the liver monitoring REMS, monthly monitoring of each patient is required for the first year the patient is on treatment, and quarterly thereafter. Following engagement with the FDA, the Company has submitted an sNDA for a potential modification to the liver-monitoring REMS.

As part of the liver monitoring REMS, monthly monitoring of each patient is required for the first year the patient is on treatment, and quarterly thereafter. The FDA accepted for review our sNDA efficacy supplement requesting modification of the frequency of liver monitoring during the first year that patients are taking FILSPARI, and assigned a PDUFA target action date of August 28, 2025. Additionally, the FDA recently notified us that the REMS for embryo-fetal toxicity is no longer necessary to ensure the benefits of FILSPARI outweigh the risk of embryo-fetal toxicity, and has instructed us to submit a REMS modification to remove the need to monitor the risk of embryo-fetal toxicity. Accordingly, we plan to submit an amendment to the REMS sNDA that is currently under review for potential modification of liver monitoring in order to effect this change. The FDA indicated that this amendment to the REMS sNDA is not expected to impact the review timeline and the Company continues to expect a REMS modification PDUFA target action date of August 28, 2025.

In April 2024, we and our partner CSL Vifor announced that the European Commission has granted conditional marketing authorization (“CMA”) for FILSPARI (sparsentan) for the treatment of adults with primary IgAN with a urine protein excretion ≥1.0 g/day (or urine protein-to-creatinine ratio ≥0.75 g/g). The CMA is granted for all member states of the European Union, as well as in Iceland, Liechtenstein and Norway. The European Commission's decision follows the positive opinion from the Committee for Medicinal Products for Human Use (“CHMP”) in February 2024, based on results from the pivotal Phase 3 PROTECT Study of FILSPARI in IgAN. Under the terms of our license agreement with CSL Vifor, we will be entitled to receive a regulatory milestone payment of $17.5 million upon receipt of full regulatory approval by the European Commission for IgAN, and we anticipate receiving an additional milestone payment upon achievement of market access initiatives in certain countries. CSL Vifor submitted an application for full regulatory approval in the second quarter of 2024. The decision on full regulatory approval, if positive, will convert the CMA to a standard Marketing Authorization (“MA”). FILSPARI became commercially available in Europe under the CMA in August 2024, with an initial launch in Germany and Austria. In October 2024, we and CSL Vifor announced that Swissmedic has granted temporary marketing authorization for FILSPARI for the treatment of adults with primary IgAN with a urine protein excretion ≥1.0 g/day (or urine protein-to-creatinine ratio ≥0.75 g/g).

In May 2023, we announced topline primary efficacy results from the pivotal Phase 3 DUPLEX Study of sparsentan in FSGS. The confirmatory primary endpoint of the DUPLEX Study designed to support traditional regulatory approval was the rate of change in eGFR over 108 weeks of treatment. At the end of the 108-week double-blind period, sparsentan was observed to have a 0.3 mL/min/1.73m 2 per year (95% CI: -1.74, 2.41) favorable difference on eGFR total slope and a 0.9 mL/min/1.73m 2 per year (95% CI: -1.27, 3.04) favorable difference on eGFR chronic slope compared to the active control irbesartan, which was not statistically significant. After 108 weeks of treatment, sparsentan achieved a mean reduction in proteinuria from baseline of 50%, compared to 32% for irbesartan. Although the DUPLEX Study did not achieve its two-year primary endpoint with statistical significance over the active control irbesartan, we are encouraged by the results, including the secondary endpoints on proteinuria and exploratory endpoints, including renal outcomes, which trended favorably for sparsentan. In addition, a review of the safety results through 108 weeks of treatment indicate sparsentan was generally well-tolerated and the overall safety profile in the study to date was generally consistent between treatment groups.

In December 2023, we announced that we completed our planned Type C meeting with the FDA to discuss results from the Phase 3 DUPLEX Study of sparsentan in FSGS. The FDA acknowledged the high unmet need for approved therapies as well as the challenges in studying FSGS but indicated that the two-year results from the Phase 3 DUPLEX Study alone were not sufficient to support an sNDA submission. The FDA acknowledged the work being done by the larger nephrology community to better understand proteinuria and eGFR as endpoints in clinical trials of FSGS and indicated a willingness to continue to engage with us on a potential path forward for sparsentan in FSGS following our consideration of additional evidence. Subsequently, a collaborative international effort referred to as the PARASOL project was initiated with a goal to define the quantitative relationships between short-term changes in biomarkers (proteinuria and GFR) and long-term outcomes in order to support the use of alternative proteinuria-based endpoints as a basis for accelerated and traditional approval. The PARASOL project is led by several patient advocacy organizations focused on glomerular diseases, with participation from regulators and industry representatives. Following the recent PARASOL public workshop in which a multi-stakeholder group of rare kidney disease experts aligned around a potential proteinuria-based clinical trial endpoint for FSGS, we have scheduled a Type C meeting with the FDA to discuss a potential regulatory pathway for a sparsentan FSGS indication.

The PARASOL project is led by several patient advocacy organizations focused on glomerular diseases, with participation from regulators and industry representatives. The principal finding from PARASOL was that in FSGS, reduction in proteinuria over 24 months is strongly associated with a reduction in the risk of kidney failure, and responder definitions based on thresholds of proteinuria are both biologically plausible and strongly supported by epidemiological data. Following the PARASOL public workshop in the fourth quarter of 2024, in which a multi-stakeholder group of rare kidney disease experts aligned around a potential proteinuria-based clinical trial endpoint for FSGS, we scheduled a Type C meeting with the FDA to discuss a potential regulatory pathway for a sparsentan FSGS indication. In February 2025, we announced that we had completed a Type C meeting with the FDA and in March 2025, we announced that we had submitted an sNDA to the FDA seeking priority review for traditional approval of FILSPARI for the treatment of FSGS. The sNDA is supported by results from the Phase 3 DUPLEX and Phase 2 DUET studies of FILSPARI. The FDA has 60 days from the receipt of the sNDA to determine whether to accept it for review. We expect 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 2025. If approved, FILSPARI could become the first and only FDA-approved medicine indicated for FSGS.

Pegtibatinase demonstrated dose-dependent reductions in total homocysteine (tHcy) during the 12 weeks of treatment, and in the highest dose cohort to date evaluating 1.5mg/kg of pegtibatinase twice weekly (BIW), treatment with pegtibatinase resulted in rapid and sustained reductions in total homocysteine (tHcy) through 12 weeks of treatment, including a 55.1% mean relative reduction in tHcy from baseline as well as maintenance of tHcy below a clinically meaningful threshold of 100 μmol. Additionally, in a dose-dependent manner in the study to date, methionine levels were substantially reduced and cystathionine levels were substantially elevated following treatment with pegtibatinase, suggesting that pegtibatinase acts in a manner similar to the native CBS enzyme.

In September 2024, we announced a voluntary pause of enrollment in the Phase 3 HARMONY Study. The voluntary enrollment pause enables us to work to address necessary process improvements in manufacturing scale-up to support commercial scale manufacturing as well as full enrollment in the HARMONY Study. Patients currently enrolled in pegtibatinase studies continue to receive study medication from small scale batches which are unaffected by the scale-up process. Currently enrolled patients will be able to continue on study medication as scheduled for the duration of the trials they are participating in. The voluntary enrollment pause was enacted following our determination that the desired drug substance profile was not achieved in the recent scale-up process. We expect to further evaluate the necessary commercial process improvements to enable the continuation of the Phase 3 program and anticipate the earliest date to restart enrollment in the Phase 3 HARMONY Study will be in 2026.

Thiola and Thiola EC are approved by the FDA for the treatment of cystinuria, a rare genetic cystine transport disorder that causes high cystine levels in the urine and the formation of recurring kidney stones. Due to the larger stone size, cystine stones may be more difficult to pass, often requiring surgical procedures to remove. More than 80 percent of people with cystinuria develop their first stone by the age of 20. More than 25 percent will develop cystine stones by the age of 10. Recurring stone formation can cause loss of kidney function in addition to substantial pain and loss of productivity associated with renal colic and stone passage. While a portion of people living with the disease are able to manage symptoms through diet and fluid intake, the prevalence of cystinuria in the US is estimated to be 10,000 to 12,000, indicating that there may be as many as 4,000 to 5,000 affected individuals with cystinuria in the US that would be candidates for Thiola or Thiola EC.

Previous wording

The increase in total net product revenues for the three and nine months ended September 30, 2024 compared to the three and nine months ended September 30, 2023 was primarily due to growth in sales of FILSPARI, including a full nine months of sales in 2024, following the February 2023 launch.

Current wording

The increase in total net product sales for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily due to growth in sales of FILSPARI.

Previous wording

The decrease in license and collaboration revenue for the three months ended September 30, 2024 compared to the three months ended September 30, 2023 was due to a $1.4 million decrease in collaboration revenue associated with the CSL Vifor License Agreement, which is derived from the performance of clinical development activities and based upon the ratio of costs incurred to total estimated costs, offset by $0.1 million in license and collaboration revenue for royalties earned in 2024 on net sales of FILSPARI in the CSL Vifor Licensed Territories following the August 2024 launch. The decrease in license and collaboration revenue for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023 was primarily due to a $4.2 million decrease in collaboration revenue associated with the CSL Vifor License Agreement as derived from the performance of clinical development activities and based upon the ratio of costs incurred to total estimated costs, and the $3.3 million sale of active pharmaceutical ingredient to CSL Vifor in March 2023, at cost plus a margin. We estimate that the remainder of the deferred revenue balance associated with these clinical development activities will be fully realized by mid-2025.

Current wording

The increase in license and collaboration revenue for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily due to the $3.8 million sale of active pharmaceutical ingredients to CSL Vifor in March 2025.

Previous wording

Cost of goods sold includes the cost of inventory sold, third party manufacturing and supply chain costs, product shipping and handling costs, and provisions for excess and obsolete inventory.

Current wording

Cost of goods sold includes the cost of inventory sold, third party manufacturing and supply chain costs, product shipping and handling costs, and provisions for excess and obsolete inventory. Cost of goods sold also includes the cost of goods sold under our license and collaboration agreements, which currently consists of the sale of active pharmaceutical ingredients to our collaboration partners, at cost or at cost plus a margin.

Previous wording

Prior to the February 2023 FDA accelerated approval of FILSPARI (sparsentan), we expensed the production of active pharmaceutical ingredients purchased to support the commercial launch of FILSPARI, in research and development expenses. For the three and nine months ended September 30, 2024 and 2023, sales of FILSPARI primarily consisted of zero-cost inventories, and therefore cost of goods sold did not increase proportionally to the increase in product sales. As of September 30, 2024, we had $2.6 million of zero-cost inventory remaining. We expect to continue to record zero cost of goods sold on the sale of previously expensed inventories through at least 2025. We began capitalizing inventory costs associated with FILSPARI following the February 2023 accelerated approval.

Current wording

Prior to the February 2023 FDA accelerated approval of FILSPARI (sparsentan), we expensed the production of active pharmaceutical ingredients purchased to support the commercial launch of FILSPARI, in research and development expenses. For the three months ended March 31, 2025 and 2024, sales of FILSPARI primarily consisted of zero-cost inventories, and therefore cost of goods sold did not increase proportionally to the increase in product sales. As of March 31, 2025, we had $1.9 million of zero-cost inventory remaining, the majority of which we expect will be consumed in 2025. We began capitalizing inventory costs associated with FILSPARI following the February 2023 accelerated approval.

Previous wording

For the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023, our cost of goods sold - license and collaboration decreased by $2.9 million, primarily due to the sale of active pharmaceutical ingredients to CSL Vifor in the first quarter of 2023.

Current wording

For the three months ended March 31, 2025 as compared to the three months ended March 31, 2024, our cost of goods sold - license and collaboration increased by $3.4 million, primarily due to the sale of active pharmaceutical ingredients to CSL Vifor in March of 2025.

Previous wording

We currently have two Phase 2 clinical trials and four Phase 3 clinical trials in process that are in various stages of activity, with ongoing non-clinical support trials. As such, clinical trial expenses will vary depending on the all the factors set forth above and may fluctuate significantly from quarter to quarter and year to year.

Current wording

Previous wording

For the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023, our research and development expenses decreased by $8.9 million and $29.8 million, respectively. Internal personnel costs to support all programs decreased by $4.0 million and $10.9 million, respectively, primarily as a result of our restructuring initiatives. External service provider costs decreased by $4.9 million and $19.0 million, respectively, which was largely driven by a decrease in costs associated with the development of sparsentan as our Phase 3 programs advance towards completion, offset by an increase in costs associated with the development of pegtibatinase following the December 2023 initiation of the Phase 3 HARMONY Study. In September 2024, we announced a voluntary pause of enrollment in the Phase 3 HARMONY Study to enable us to work to address necessary process improvements in manufacturing scale-up to support commercial scale manufacturing as well as full enrollment in the HARMONY Study. As a result of this pause, certain previously planned investments related to clinical enrollment in HARMONY and large-scale production are expected to be delayed beyond 2025. Together with the expected decline in costs associated with the development of sparsentan as the Phase 3 programs advance towards completion, we expect that research and development expenses will be reduced in 2025 compared to 2024.

Current wording

For the three months ended March 31, 2025 as compared to the three months ended March 31, 2024, our research and development expenses decreased by $2.5 million. External service provider costs decreased by $2.9 million, which was largely driven by a decrease in costs associated with the development of sparsentan as our Phase 3 programs advance towards completion.

Previous wording

In March 2024, we recognized $65.2 million in in-process research and development (IPR&D) expense upon the achievement of a development milestone associated with our treatment candidate pegtibatinase, which we acquired as part of the November 2020 acquisition of Orphan Technologies Limited.

Current wording

Previous wording

The change in our total other income, net for the three and nine months ended September 30, 2024 as compared to the three and nine months ended September 30, 2023, is partly attributable to changes in interest income, driven by a decrease in the overall balance of interest-bearing security investments held along with fluctuations in short-term interest rates on those investments. For the nine months ended September 30, 2024, we recognized $3.4 million in other expense in connection with our equity investment in Renalys, for basis adjustments related to the IPR&D as measured at inception.

Previous wording

We have financed our operations through a combination of borrowings, sales of our equity securities, and revenues generated from our commercialized products, along with proceeds from license and collaboration agreements and the divestiture of our bile acid business. We experienced significant growth in recent years in the number of our employees and the scope of our operations. We also expanded our sales and marketing, compliance and legal functions in addition to expansion of all functions to support a commercial organization, including by adding additional members to our sales force in connection with the recent commercial launch of FILSPARI in the United States for IgAN. In December 2023, we implemented an approximate 20% workforce reduction focused on non-field-based employees in an effort to align our resources on the ongoing FILSPARI launch and the pivotal Phase 3 HARMONY Study to support the potential approval of pegtibatinase as the first potential disease-modifying treatment for HCU. These restructuring adjustments are expected to result in an estimated annualized savings of approximately $25.0 million in 2024.

We believe that our available cash and short-term investments as of the date of this filing, together with anticipated cash generated from operations, will be sufficient to fund our anticipated level of operations beyond the next 12 months. We expect that our operating results will vary from quarter-to-quarter and year-to-year depending upon various factors including revenues, selling, general and administrative expenses, and research and development expenses, particularly with respect to our clinical and preclinical development activities. Our ability to fund our operations in subsequent years will depend upon certain factors which are beyond our control and may require us to obtain additional debt or equity capital or refinance all or a portion of our debt, including the 2025 Notes and 2029 Notes, on or before maturity. Though we generate revenues from product sales arrangements, we may incur significant operating losses over the next several years. Our ability to achieve profitable operations in the future will depend in large part upon completing development of products in our pipeline, obtaining regulatory approvals for these products and bringing these products to market, along with potential in-licensing of additional products approved by the FDA and selling and manufacturing these products.
