Travere Therapeutics to Present New FILSPARI® (sparsentan) Data at the 62nd ERA Congress
Data from SPARTACUS and PROTECT OLE to show significant proteinuria reduction when replacing RASi with FILSPARI and when FILSPARI is used in combination with SGLT2i New mechanistic data to show FILSPARI protects against IgA deposition in the kidney SAN DIEGO, June 03, 2025--(BUSINESS WIRE)--Travere Therapeutics, Inc., (Nasdaq: TVTX) today announced that the Company will present seven abstracts at the upcoming European Renal Association (ERA) Congress in Vienna, Austria, June 4-7. Presentations will include new data on the use of FILSPARI in IgA nephropathy (IgAN) from the Phase 2 SPARTACUS Study which demonstrated that FILSPARI provided clinically meaningful benefits in adults with IgAN who replaced their renin-angiotensin system inhibitor (RASi) with FILSPARI while receiving stable sodium-glucose cotransporter-2 inhibitor (SGLT2i) therapy. A presentation on results from the open label extension (OLE) of the Phase 3 PROTECT Study will show that patients previously treated with maximum labeled irbesartan experienced significant proteinuria reduction after switching to FILSPARI in the study. In a preclinical model of IgAN, FILSPARI protected from mesangial deposition of IgA, suggesting a potential role of endothelin-1 and angiotensin II as modulators of disease activity in IgAN. Data from the gddY mouse model of IgAN will offer new insight into the pathogenesis of IgAN as a tissue-specific autoimmune disease. In focal segmental glomerulosclerosis (FSGS), the Company will share a data analysis from the Phase 3 DUPLEX Study showing that partial and complete proteinuria remission were achieved earlier and more frequently with FILSPARI than irbesartan. The Company will also present preclinical data in an animal model of immune-mediated FSGS showing that optimized dual endothelin and angiotensin blockade with FILSPARI helps protect the integrity of the glomerular filtration barrier, reducing glomerular permeability and lowering albuminuria. "The breadth of data we're presenting underscores our confidence in the role FILSPARI can serve as foundational therapy for rare kidney diseases," said Jula Inrig, M.D., chief medical officer of Travere Therapeutics. "These findings provide further evidence that FILSPARI can decrease the risk of IgAN disease progression. We are deeply committed to advancing research and delivering innovative therapies that can make a meaningful difference for people living with IgAN and FSGS."

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 Focal Segmental Glomerulosclerosis Focal segmental glomerulosclerosis (FSGS) is a rare proteinuric kidney disorder in both children and adults that is estimated to affect more than 40,000 patients in the U.S. with similar prevalence in Europe. The disorder is defined by progressive scarring of the kidney and often leads to kidney failure. FSGS is characterized by proteinuria, where protein leaks into the urine due to a breakdown of the normal filtration mechanism in the kidney. Once in the urine, protein is considered to be toxic to other parts of the kidney, especially the tubules, and is believed to contribute to further disease progression. Other common symptoms include swelling in parts of the body, known as edema, as well as low blood albumin levels, abnormal lipid profiles and hypertension. Sparsentan is not approved for use in FSGS. There is currently no approved pharmacologic indicated for the treatment of FSGS. About Travere Therapeutics At Travere Therapeutics, we are in rare for life.

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 ( 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. Please see the full Prescribing Information, including BOXED WARNING, for additional Important Safety Information.

Vera Therapeutics Announces Refinancing of Existing Oxford Debt Facility, Providing up to $500 Million of Term Loans
BRISBANE, Calif., June 03, 2025 (GLOBE NEWSWIRE) -- Vera Therapeutics, Inc. ('Vera'), a late clinical-stage biotechnology company focused on developing and commercializing transformative treatments for patients with serious immunological diseases, today announced that it has entered into a new credit facility providing for up to $500 million of term loans with its current partner Oxford Finance LLC ('Oxford'). The new credit facility will replace Vera's existing $50 million credit facility. The initial funding of the new credit facility will be in a principal amount of $75 million and is expected to occur on June 4, 2025. Highlights of the new credit facility include: Lowered Interest Rate: Reduced borrowing cost by 320 basis points based on current interest rates. The facility will mature five years from the closing date. Interest will be paid monthly at a rate per annum equal to 1-month SOFR plus 4.95%, subject to a SOFR floor of 3.75%. Increased Capital Availability: Added $450 million of discretionary incremental capacity available in five tranches. At its discretion, Vera may draw up to $50 million from January 1, 2026 through December 31, 2026, not subject to additional performance milestones. Vera has the option to draw $75 million upon accelerated approval of atacicept in immunoglobulin A nephropathy (IgAN), two $50 million tranches post accelerated approval and subject to commercial milestones, and up to $200 million at the mutual discretion of Vera and Oxford. Improved Structure & Financial Flexibility: Extended the interest only period by up to 42 months and maturity by up to 41 months. As a result of this refinancing, Vera will no longer be required to make principal payments in 2026. The new facility also reduced prepayment and final-payment fees and, combined with the reduced interest rate, results in a cost-effective refinancing that significantly lowers Vera's cost of capital. 'We have crossed a significant Vera milestone with the primary endpoint results from the pivotal atacicept ORIGIN 3 trial; and given the data we presented earlier, we expect this to enable a BLA submission to the FDA in the fourth quarter of this year, which may allow for approval and commercial launch in 2026. If approved, we believe that atacicept has the potential to advance the standard of care in IgA nephropathy,' said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. 'The Vera team is well-positioned to build on the success of the lead atacicept development program in IgAN, with the expansion into additional potential indications in other autoimmune kidney diseases and beyond.' The refinancing significantly reduces interest expense and improves financial flexibility and access to capital as compared to the existing credit facility, with the new credit facility having more borrower-favorable terms overall than those under the existing credit facility. The refinancing enhances Vera's ability to generate cash and manage its capital structure efficiently while providing additional working capital flexibility to support commercial launch and strategic initiatives. 'Our partnership with Oxford over the past three years has been key to supporting Vera's growth and we are happy to continue this incredibly productive relationship,' said Sean Grant, Chief Financial Officer of Vera. 'We are also very pleased to be able to execute this non-dilutive transaction in today's market environment with Oxford. Through a competitive process, we secured favorable terms with our current lender, eliminated exit fees from the existing credit facility, and closed the refinancing in a very efficient manner.'A Form 8-K outlining the full terms of the new credit facility will be filed with the Securities and Exchange Commission. Armentum Partners acted as exclusive financial advisor to Vera. Latham and Watkins LLP served as legal advisor to Vera, and Manatt, Phelps and Phillip, LLP served as legal advisor to Oxford. About VeraVera Therapeutics, Inc. is a late clinical-stage biotechnology company focused on developing treatments for serious immunological diseases. Vera's mission is to advance treatments that target the source of immunological diseases in order to change the standard of care for patients. Vera's lead product candidate is atacicept, a fusion protein self-administered as a subcutaneous injection once weekly that blocks both B-cell Activating Factor (BAFF) and A PRoliferation-Inducing Ligand (APRIL), which stimulate B cells to produce autoantibodies contributing to certain autoimmune diseases, including IgAN and lupus nephritis. In addition, Vera is evaluating additional diseases where the reduction of autoantibodies by atacicept may prove medically useful. Vera also holds an exclusive license agreement with Stanford University for a novel, next generation fusion protein targeting BAFF and APRIL, known as VT-109, with wide therapeutic potential across the spectrum of B cell mediated diseases. Vera is also developing MAU868, a monoclonal antibody designed to neutralize infection with BK virus (BKV), a polyomavirus that can have devastating consequences in certain settings such as kidney transplant.

Vera drug scores in closely watched study in rare kidney disease
This story was originally published on BioPharma Dive. To receive daily news and insights, subscribe to our free daily BioPharma Dive newsletter. An experimental medicine from Vera Therapeutics succeeded in a late-stage trial in a rare kidney disease, positioning the company to discuss an approval application with U.S. regulators in the near future. According to Vera, the drug, called atacicept, met its main goal in a Phase 3 trial in IgA nephropathy, a chronic condition that can lead to kidney failure. After 36 weeks of treatment, atacicept was associated with a 42% reduction versus a placebo — and a 46% decline from the study's start — in the amount of protein in participants' urine, an important marker of kidney health. Without providing specifics, Vera said atacicept's other efficacy results were 'consistent with or better than' what was observed in mid-stage testing and had a safety profile 'comparable to placebo.' The company will share the data with the Food and Drug Administration in the coming weeks and intends to file an accelerated approval request in the fourth quarter. Vera is one of the leaders in a push to develop new treatments for IgA nephropathy, or IgAN, a progressive disease that damages the kidneys. Some estimates hold 130,000 to 150,000 people in the U.S. have IgAN. While several medicines are approved, they don't totally stop patients' kidney function from deteriorating. That need, and a better understanding of the disease's biology, has led to an uptick in dealmaking involving IgAN. Drugs recently launched by Travere Therapeutics and Calliditas Therapeutics have performed well, too. Vera's atacicept is part of a newer wave of therapies aimed at immune-mediated drivers of the disease. Like several others in development, it targets a pair of cytokines called BAFF and April that stimulate production of the 'autoantibodies' that mistakenly target the body's own tissue. In Phase 2 testing, the drug stabilized a key marker of disease progression so well that some analysts viewed the findings as the bar for other competitors to meet. The findings also heightened anticipation for Vera's Phase 3 study. According to Marshall Fordyce, Vera's founder and CEO, the drug's effects on urine protein in the trial significantly 'exceed the bar' for what U.S. regulators have accepted in granting an accelerated approval to several other medications. The figure Vera reported also represents the 'deepest reduction' in a late-stage stage study in IgAN patients to date, he wrote in an email. Investors appear to agree, as Vera's shares climbed by nearly 60%, to over $30 apiece, in early trading on Monday. Vera has competition ahead, as Otsuka Pharmaceutical could win approval of a similar type of medicine by late November. The company will present detailed Phase 3 study results at a medical meeting on Friday and, though cross-trial comparisons come with caveats, analysts and investors will be paying close attention to how the two treatments stack up. Vera, for its part, believes the market for IgAN treatments is 'ripe for disruption,' according to Fordyce. There are currently 'low levels of approved product saturation,' Fordyce wrote, and newer drugs like atacicept 'may represent a differentiated approach.' The company is also studying the drug in people whose are at 'moderate' or 'low' risk of disease progression, which, if successful, could boost its sales potential. The Phase 3 trial, meanwhile, will continue on while Vera accumulates data on atacicept's impact on kidney function. Those findings are expected in 2027. Vera's results have implications for drugmakers like Biogen and Vertex Pharmaceuticals, which have both cut deals for companies developing IgAN drugs. Vertex has said it could file for approval of a drug that also targets BAFF and April early next year, if data are supportive.

Biohaven Ltd. (BHVN)'s BHV-1400 Cuts Disease Antibody by 81% in IgA Nephropathy
Biohaven Ltd. (NYSE:BHVN) has announced major breakthroughs with its novel precision immunology therapies, BHV-1400 and BHV-1300, at its 2025 R&D Day in New Haven. BHV-1400, a first-in-class TRAP degrader, achieved up to 81% reduction in galactose-deficient IgA1 (Gd-IgA1), the key driver of IgA nephropathy (IgAN), after a single subcutaneous dose, with effects lasting for weeks. A patient viewing their medical diagnosis on a digital healthcare ecosystem. Unlike traditional immunosuppressive treatments, BHV-1400 precisely eliminates pathogenic Gd-IgA1 while sparing healthy antibodies (IgA, IgG, IgE, IgM), preserving overall immune function and offering a superior safety profile. This selectivity sets it apart from complement and BLyS/APRIL inhibitors, which can compromise broader immunity. Encouraged by these results, Biohaven Ltd. (NYSE:BHVN) will launch a pivotal IgAN trial in 2026 using the urine protein-creatinine ratio as an accelerated approval endpoint. Simultaneously, BHV-1300, targeting IgG-mediated diseases like Graves' Disease, demonstrated rapid, deep, and sustained total IgG reductions of up to 87% in Phase 1, with flexible dosing for acute and chronic management. Both therapies were well-tolerated, with no serious adverse events. Biohaven Ltd. (NYSE:BHVN) plans pivotal trials for BHV-1300 in Graves' Disease in the second half of 2025, reinforcing its leadership in precision immunology. While we acknowledge the potential of BHVN to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk. If you are looking for an AI stock that is more promising than BHVN and that has 100x upside potential, check out our report about this READ NEXT: and Disclosure: None.

FILSPARI to Transform Kidney Disease Care with Its Revolutionary Treatment Approach
FILSPARI holds strong market potential as the first FDA-approved non-immunosuppressive therapy for IgA nephropathy, a rare kidney disease with significant unmet needs. As more patients and providers seek disease-modifying options, FILSPARI is well-positioned to capture substantial market share, especially with favorable long-term data. LAS VEGAS, May 27, 2025 /PRNewswire/ -- DelveInsight's "FILSPARI Market Size, Forecast, and Market Insight Report" highlights the details around FILSPARI, the first and only oral, once-daily, non-immunosuppressive therapy approved in both the US and Europe for IgAN. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of FILSPARI. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. Travere Therapeutics' FILSPARI (sparsentan) Overview FILSPARI (sparsentan) is a once-daily oral treatment that uniquely targets two key pathways, endothelin-1 and angiotensin II (also known as DEARA), in the progression of IgA nephropathy. It is the first approved non-immunosuppressive therapy for this condition. Endothelin-1 and angiotensin II contribute to kidney function decline by promoting inflammation and fibrosis, altering podocyte structure, causing podocyte loss, and increasing the permeability of the glomerular filtration barrier. Additionally, both are vasoconstrictors that narrow blood vessels and raise pressure in the glomeruli. The drug received accelerated approval based on its ability to reduce proteinuria. Due to potential safety concerns, it is distributed under the FILSPARI Risk Evaluation and Mitigation Strategy (REMS) program. In Europe, it is marketed by CSL Vifor, and in Japan by Renalys Pharma. Results from the registration-enabling study are expected in the second half of 2025. Drug Name FILSPARI (sparsentan) Molecule type Small molecule Developer Travere Therapeutics Primary Indication Immunoglobulin A nephropathy FILSPARI MoA ETAR antagonist; AT1R antagonist Route of administration Oral Learn more about FILSPARI projected market size for IgAN @ FILSPARI IgA Nephropathy IgA nephropathy (IgAN) is an autoimmune disorder that disrupts kidney function by damaging the small blood vessels responsible for filtration. This damage is caused by an abnormal protein that harms the glomeruli, the kidneys' main filtering units. According to DelveInsight, there were approximately 415,000 diagnosed prevalent cases of IgAN across the seven major markets in 2024, and this number is projected to grow at a CAGR of 0.6% through 2034. Current standard care involves the use of ACE inhibitors and angiotensin II receptor blockers (ARBs), primarily to manage associated symptoms like hypertension. Currently, only a few drugs have been approved for IgAN treatment, including VANRAFIA (Atrasentan) and FABHALTA (Iptacopan) by Novartis, FILSPARI (Sparsentan) by Travere Therapeutics, and TARPEYO/KINPEYGO (budesonide) by Asahi Kasei (Calliditas Therapeutics), among others. The treatment landscape is expected to undergo major changes between 2024 and 2034, driven by the introduction of innovative therapies. DelveInsight estimates the IgAN market across the seven key regions was valued at around USD 730 million in 2024 and is projected to grow at a strong CAGR of 30.5% from 2025 to 2034. With targeted treatment options for IgAN only recently emerging and a pressing need for therapies that can delay progression to end-stage kidney disease (ESKD), significant advancements in this area are likely to profoundly reshape the market in the coming years. Discover more about the IgAN market in detail @ IgA Nephropathy Market Assessment Emerging Competitors of FILSPARI Key companies advancing therapies for IgA nephropathy include Novartis (Zigakibart/FUB523), F. Hoffmann-La Roche and Ionis Pharmaceuticals (Sefaxersen/RG6299/IONIS-FB-LRx), AstraZeneca's Alexion Pharmaceuticals (ULTOMIRIS), Vera Therapeutics (Atacicept), Vertex Pharmaceuticals (Povetacicept), Otsuka Pharmaceutical (Sibeprenlimab), Biogen (Felzartamab), Arrowhead Pharmaceuticals (ARO-C3), NovelMed (NM8074), Q32 Bio (ADX-097), Walden Biosciences (WAL0921), and Takeda Pharmaceutical (TAK-079), among others. In April 2025, Vera Therapeutics announced it had completed patient enrollment for its pivotal Phase III ORIGIN trial assessing atacicept in IgA nephropathy. The previous month, Otsuka Pharmaceutical submitted a Biologics License Application (BLA) to the FDA for sibeprenlimab, a monoclonal antibody aimed at inhibiting APRIL (A PRoliferation-Inducing Ligand) in adults with IgAN. Additionally, in July 2022, the European Commission granted Orphan Drug Designation (ODD) to BION-1301 for primary IgAN, offering regulatory benefits to support its European development. Strengthening its renal pipeline, Novartis acquired Chinook Therapeutics in August 2023 for up to $3.5 billion, adding zigakibart and other late-stage kidney-focused assets to its portfolio. To know how does FILSPARI compare to other treatments for IgA nephropathy, visit @ FILSPARI Approval Date Key Milestones of FILSPARI In November 2024, FILSPARI was approved by the MHRA for primary IgAN treatment, and sparsentan received approval in Germany for the same indication. In September 2024, the FDA granted full approval for FILSPARI to slow kidney function decline in IgAN patients, based on positive long-term results from the PROTECT Study. In April 2024, CSL Vifor and Travere Therapeutics received Conditional Marketing Authorization (CMA) from the European Commission for FILSPARI in the EU, targeting adults with IgAN and significant proteinuria. In February 2023, the US FDA granted accelerated approval to FILSPARI (sparsentan) to reduce proteinuria in adults with primary IgAN at risk of rapid progression, with priority review. Discover how FILSPARI is shaping the IgAN treatment landscape @ FILSPARI IgAN FILSPARI Market Dynamics FILSPARI, developed by Travere Therapeutics, represents a significant advancement in the treatment of IgA Nephropathy, a rare and chronic autoimmune kidney disease. Approved under the FDA's accelerated approval program in early 2023, FILSPARI is the first non-immunosuppressive therapy specifically targeting proteinuria in IgAN. It is a dual endothelin angiotensin receptor antagonist (DEARA), a novel mechanism that distinguishes it from conventional RAAS inhibitors. Its market entry has been notable for both its scientific innovation and potential to reshape the standard of care for IgAN, particularly in patients at high risk of progression to end-stage kidney disease (ESKD). The market dynamics are influenced by multiple factors, including the unmet need in IgAN, the orphan drug designation, and the limited competition in the space. Prior to FILSPARI's launch, treatment was largely supportive, focusing on blood pressure control and proteinuria reduction via ACE inhibitors or ARBs. FILSPARI's ability to deliver greater proteinuria reduction without the side effects associated with corticosteroids or immunosuppressants provides a compelling clinical and commercial value proposition. Competition is evolving, with several companies advancing novel IgAN therapeutics. Calliditas Therapeutics' TARPEYO (budesonide) was approved ahead of FILSPARI for a similar indication, but works through a corticosteroid pathway. Other players are also advancing programs, suggesting the market could become more segmented based on patient profile and mechanism of action. FILSPARI's differentiated profile, especially its dual-acting mechanism and oral administration, positions it favorably among nephrologists and specialists, but maintaining this edge will require strong real-world evidence and ongoing clinical data. From a market access and adoption standpoint, Travere has made early efforts in physician education, patient support programs, and collaboration with nephrology groups to accelerate uptake. However, broader adoption will depend on securing favorable formulary placements, long-term safety data, and sustained efficacy in delaying disease progression. As IgAN awareness grows and diagnosis rates improve through genetic and biomarker testing, the addressable patient population may expand, offering a significant growth opportunity for FILSPARI over the next 5–10 years.
