Otsuka Sibeprenlimab Phase 3 Data Show a Statistically Significant and Clinically Meaningful Proteinuria Reduction for the Treatment of Immunoglobulin A Nephropathy (IgAN)
In the Phase 3 VISIONARY study, sibeprenlimab achieved a statistically significant and clinically meaningful 51.2% (P<0.0001) reduction in proteinuria at nine months of treatment when compared to placebo The safety profile of sibeprenlimab was favorable and consistent with previously reported data Immunoglobulin A nephropathy is a progressive, immune-mediated, chronic kidney disease that can lead to end-stage kidney disease (ESKD) over the lifetime of most patients under current optimized standard care Sibeprenlimab filed its Biologics License Application (BLA) and received Priority Review designation from the U.S. Food and Drug Administration (FDA) with a target action date of November 28th, 2025 PRINCETON, N.J. & TOKYO, June 06, 2025--(BUSINESS WIRE)--Otsuka Pharmaceutical Development & Commercialization, Inc. and Otsuka Pharmaceutical, Co. Ltd. (Otsuka) today presented results from a pre-specified interim analysis of the Phase 3 VISIONARY study (NCT05248646) evaluating sibeprenlimab, for the treatment of immunoglobulin A nephropathy (IgAN) in adults. Patients treated with sibeprenlimab achieved a 51.2% (P<0.0001) reduction in proteinuria (as measured by 24-hour uPCR [urine protein-to-creatinine ratio]) at nine months of treatment when compared to placebo1. The data were presented during a late-breaking clinical trials session at the European Renal Association (ERA) Congress in Vienna, Austria. The study, the largest Phase 3 IgAN trial conducted to date, also showed the safety profile of sibeprenlimab was favorable and consistent with previously reported data1. Specifically, 76.3% of patients treated with sibeprenlimab experienced any Treatment Emergent Adverse Event (TEAE) versus 84.5% in the placebo group.1 Patients who experienced a serious TEAE were 3.9% treated with sibeprenlimab compared to 5.4% treated with placebo. Sibeprenlimab received Priority Review designation from the FDA last month following its BLA filing in March. Proteinuria reduction is a recognized surrogate marker correlating with delaying progression to kidney failure and has been used as an endpoint in IgAN clinical trials to support accelerated regulatory approvals2. Sibeprenlimab is an investigational monoclonal antibody that selectively inhibits the activity of APRIL (A PRoliferation-Inducing Ligand) in adults with IgAN. APRIL plays a key role in the 4-hit process of IgAN pathogenesis and is an important initiating and sustaining factor in IgAN progression by promoting the production of pathogenic Gd-IgA1 and immune complex formation3,4,5,6. By selectively binding and inhibiting APRIL, sibeprenlimab reduces the amount of immunoglobulin A (IgA) and Gd-IgA1 levels1. Lower levels of Gd-IgA1 in people with IgAN provide less substrate for immune complex formation7. Sibeprenlimab is administered in a single-dose prefilled syringe for subcutaneous injection every four weeks intended for self-administration or administration by caregiver, providing patients the option of convenience at home. "We are confident about the potential of sibeprenlimab and are grateful to the patients who are helping to further the science by participating in these important trials," said John Kraus, M.D., Ph.D., executive vice president and chief medical officer, Otsuka Pharmaceutical Development & Commercialization, Inc. "Proteinuria control is an important independent predictor for long-term prognosis, and this interim data reinforces our belief that selectively targeting APRIL has the potential to be an effective and safe approach for this progressive and irreversible kidney disease." The VISIONARY study continues in a blinded manner to evaluate the change in kidney function over 24 months as measured by estimated glomerular filtration rate (eGFR) and is expected to be completed in early 2026. Further prespecified and exploratory analyses of the data will be conducted to determine the full potential of sibeprenlimab for the treatment of IgAN1. "The VISIONARY Phase 3 interim analysis shows a robust proteinuria reduction of 51.2% in the group treated with sibeprenlimab relative to placebo. These results affirm our belief in the efficacy of sibeprenlimab in the largest Phase 3 IgAN trial to date. The study enrolled a diverse patient population reflective of the disease epidemiology," said Dr. Dana Rizk, professor of medicine in the division of nephrology at the University of Alabama at Birmingham. "The safety data emerging from VISIONARY is reassuring and adds to our existing knowledge about sibeprenlimab's safety profile from prior programs. This is very exciting news for patients and adds a therapeutic option with a novel mechanism of action potentially targeting the immunologic pathogenesis of IgAN." About the VISIONARY Study The VISIONARY study is the largest IgAN trial to date, and is a multicenter, randomized, double-blind, placebo-controlled trial consisting of approximately 510 adult patients with IgAN who were receiving standard-of-care therapy (defined as maximally tolerated ACE inhibitor or ARB +/- SGLT2 inhibitor), designed to evaluate the efficacy and safety of sibeprenlimab 400 mg administered subcutaneously every four weeks, compared to placebo1. The primary efficacy endpoint is to evaluate the change in 24-hour uPCR at 9 months compared with baseline. The secondary endpoint is to evaluate the annualized slope of eGFR estimated over ~24 months1. About Sibeprenlimab Sibeprenlimab (formerly VIS649) was designed and engineered by Visterra, Inc., a wholly owned subsidiary of Otsuka. Pre-clinical and early-stage trials of sibeprenlimab were also conducted by Visterra. Sibeprenlimab is an investigational monoclonal antibody that selectively binds to and inhibits the activity of APRIL and plays a key role in the 4-hit process. By selectively binding and inhibiting APRIL, sibeprenlimab reduces the amount of immunoglobulin A (IgA) and Gd-IgA1 levels1. Lower levels of Gd-IgA1 in people with IgAN provide less substrate for immune complex formation7. Decreased immune complex formation should result in diminished deposition in the kidney, and reduced proteinuria and kidney inflammation8. By reducing the production of Gd-IgA1, sibeprenlimab may help slow kidney damage and progression toward ESKD3,4,5,6. By inhibiting APRIL, sibeprenlimab may help address one of the IgAN-specific drivers for nephron loss. About IgAN and APRIL IgAN is a progressive, immune-mediated, chronic kidney disease that typically manifests in adults aged 20-40 years and leads to ESKD over the lifetime of most patients9,10,11. IgAN is characterized by the accumulation of Gd-IgA1 complexes in the kidneys. IgAN can lead to progressive loss of kidney function and, eventually, ESKD, imposing a significant burden on patients10. Despite supportive care, there is an unmet need for treatments that address the root causes of the condition. Continued research in the disease remains crucial to uncovering opportunities for advancement in our understanding and treatment of patients 5. APRIL, a cytokine in the tumor necrosis factor (TNF) family, is integral to the pathogenesis and progression of IgAN. It promotes the survival and class switching of B cells to produce IgA, particularly the pathogenic galactose-deficient IgA1 (Gd-IgA1) that forms immune complexes in the kidneys5.

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.

Biohaven Highlights Innovation and Advancement Across MoDE and TRAP Degrader Platform at R&D Day, Announcing Positive TRAP Degrader Data Achieving > 80% Sustained Reductions in Galactose-Deficient IgA1 (Gd-IgA1) with Potential First-in-Class BHV-1400 for IgA Nephropathy (IgAN)
Optimized subcutaneous (SC) administration of BHV-1400 achieved rapid, deep, selective, and sustained lowering of Gd-IgA1, differentiating Biohaven's leading TRAP degrader for IgAN from the complement and BLyS/APRIL inhibitor competition. Up to 81% reduction of Gd-IgA1 was observed, with reductions from baseline sustained for weeks after a single SC dose administration. BHV-1400 brings precision immunology to the treatment landscape of IgAN as it was rationally designed to selectively remove galactose-deficient IgA1 (Gd-IgA1), the pathogenic antibody driver of the disease while sparing healthy antibodies IgA, IgG, IgE, and IgM. Preservation of immunoglobulins, the complement system, and cell-mediated and humoral immunity offers key differentiation against immunosuppressive BLyS/APRIL inhibitors, complement inhibitors, and budesonide. Based upon the rapid and deep reductions of Gd-IgA1 observed with subcutaneous BHV-1400, Biohaven plans to study BHV-1400 in patients with IgAN, initiating a pivotal trial in 2026 using urine protein-creatinine ratio (UPCR) as a surrogate endpoint for accelerated approval. Optimized SC administration of BHV-1300 has continued to demonstrate rapid, deep, and sustained lowering of total IgG in Phase 1 studies. Recently generated clinical data shows that BHV-1300 achieved rapid, deep, and sustained lowering of total IgG, with reductions up to 87%. Median maximum reductions of 83% were observed within 18 days of the first subcutaneous dose. The range of IgG reductions possible with varying dosing paradigms of BHV-1300 allows for tunable dosing regimens tailored for acute and chronic disease management, with higher doses for acute disease management and lower, less frequent dosing for chronic disease management. Based upon the rapid and deep reductions of IgG and favorable tolerability profile observed with BHV-1300, Biohaven plans to study BHV-1300 in patients with Graves' Disease and initiate pivotal trials in 2H 2025. NEW HAVEN, Conn., May 28, 2025 /PRNewswire/ -- Biohaven Ltd. (NYSE: BHVN) ("Biohaven"), a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies to treat a broad range of rare and common diseases, today highlighted the success of its first MoDE™ and TRAP™ degraders in achieving key target pharmacodynamic endpoints and announced plans to initiate pivotal trials in Graves' Disease and in IgA nephropathy in 2H 2025 and 1H 2026, respectively at Biohaven's 2025 R&D Day, held concurrently with the Yale Innovation Summit in New Haven, Connecticut. The presentation slides from Biohaven's R&D day for the TRAP and MoDE degraders and its other platforms will be available on the Events and Presentations page of the Biohaven website just prior to their presentations. BHV-1400, the Company's potential first-in-class galactose-deficient IgA1 (Gd-IgA1) TRAP degrader for the treatment of IgA nephropathy (IgAN) achieved deep, rapid, and sustained reductions in Gd-IgA1. In the Phase 1 study, a single dose of BHV-1400 was subcutaneously administered at a dose of 500 mg and achieved rapid, deep and sustained reductions in Gd-IgA1 of up to 81%, with a median reduction of 66% (Figure 1). Reductions occurred within hours of each dose, were progressive, and were sustained for weeks after a single dose administration. Effects were selective, with no significant reductions observed in other immunoglobulins: IgA, IgG, IgE, or IgM. Dr. Jonathan Barratt, the Mayer Professor of Renal Medicine at University of Leicester and leading expert in the treatment of IgAN, commented on the new Phase 1 data, "The reason I am excited about BHV-1400 is because it specifically targets the fundamental abnormality in IgA nephropathy while leaving the rest of the immune system untouched. It has the potential to take away the major driver for immune complex formation while leaving other antibodies completely unaffected, which means it has efficacy with unrivaled safety." IgA nephropathy is the leading cause of glomerular disease globally and is commonly diagnosed in individuals in their second and third decades of life, with most individuals progressing to renal failure over the ensuing 10-15 years. As a disease of the immune system, IgA nephropathy frequently returns even after renal transplant. While the 2021 Kidney Disease Improving Global Outcomes (KDIGO) treatment guidelines recommended only standard chronic kidney disease treatments, the 2024 draft guidelines emphasize the importance of treating the underlying immune disease by removing aberrant forms of IgA. "Galactose deficient IgA1 is the fundamental abnormality in IgA nephropathy," Dr. Barratt explained, "It's a group of IgA molecules that have changes to the sugars on the IgA1 hinge region that fundamentally change the way this antibody behaves. It promotes immune complex formation and it's these immune complexes that cause glomerular injury and damage and promote loss of kidney function." BHV-1400's selective approach has the potential to offer an improved safety profile compared to broadly immunosuppressive agents. BHV-1400 has been safe and well-tolerated across the ongoing Phase 1 study. Most adverse events (AEs) were mild and self-resolving, there were no discontinuations due to AEs related to study drug, and there were no serious or severe AEs related to drug. There were no clinically significant increases in ALT, AST or bilirubin, no clinically significant reductions in albumin and no clinically significant increases in cholesterol relative to placebo over the 4-week dosing period. There were no clinically significant reductions in other immunoglobulins including IgG, IgA, IgE, or IgM relative to baseline. With regards to the applicability of Phase 1 data in healthy volunteers to patients with IgAN, Dr. Barratt added, "It's not that the Gd-IgA1 is subtly different, it's the same in both (healthy volunteers and patients with IgAN), but in patients, they just have an excess quantity. And so, what I believe is that because you're seeing a suppressed Gd-IgA1 in healthy subjects you are going to see the same in patients with IgA nephropathy, and indeed that's what some of the drugs targeting BAFF and APRIL have shown. They presented data in their healthy volunteer population that was precisely replicated when they went in to patients." BHV-1400 fundamentally differentiates from alternative approaches by virtue of its precision. While agents targeting the glucocorticoid receptors may have steroid-like side effects, those targeting complement require vaccination for encapsulated bacterial infections, and B-cell-directing therapies cause reductions in all isotypes of immunoglobulin, potentially increasing long-term infection risk. Based upon the rapid and deep reductions of Gd-IgA1 observed with SC dosing of BHV-1400, Biohaven plans to study BHV-1400 in patients with IgAN and initiate pivotal trials in 2026 using UPCR surrogate endpoint via the accelerated approval pathway. At its R&D Day, Biohaven also released new positive data from its completing Phase 1 study of its leading MoDE degrader, BHV-1300, that targets IgG for removal. In the Phase 1 multiple-dose study, SC administered BHV-1300 achieved IgG reductions up to 87%. Median maximum reductions of 83% were achieved within 18 days (Figure 2). Biohaven recently reported the 1000 mg weekly dose achieved rapid, deep and sustained reductions in total IgG of up to 84%, with a median reduction of 80% by Week 4 (Figure 2). Reductions at all doses occurred within hours of administration, were progressive, and effects were durable between dosing intervals. The range of IgG lowering enabled by different dose levels of BHV-1300 offers tunability and flexibility in dosing paradigm, with higher doses planned for management of acute conditions, and lower, less frequent dosing planned for the management of chronic disease. BHV-1300 has been safe and well-tolerated in subcutaneous doses up to 2000 mg with no clinically significant increases in ALT, AST, or bilirubin, no clinically significant reductions in albumin, and no clinically significant increases in cholesterol over the four-week dosing period relative to placebo. There were no clinically significant reductions in IgG3, IgA, IgE, or IgM relative to baseline. Most AEs were mild and self-resolving, and there were no serious or severe AEs. BHV-1300 is a potential first-in-class novel small molecule MoDE degrader in development for the treatment of IgG-mediated diseases, such as Graves' Disease. It is designed for self-administration via an easy-to-use and patient-friendly autoinjector. Biohaven plans to study BHV-1300 in patients with Graves' Disease and initiate a pivotal trial in 2H 2025. Tova Gardin, MD, MPP, Chief Translational Officer at Biohaven, commented, "Our lead MoDE and TRAP degraders, BHV-1300 and BHV-1400, deliver on the promise of ground-breaking chemistry, demonstrating unrivaled selectivity, and profound depletion of potentially disease-causing proteins. With the selectivity of the platform and the initial profile observed in Phase 1, we aim to bring precision immunology to patients with safe and effective treatments that target the core of disease biology. We are incredibly proud of our innovative, agile, and dynamic team that has catalyzed a first of its kind extracellular degrader technology from bench to the clinic. Driven by patient need and leading-edge, mechanistically precise science, Biohaven remains focused on delivering the promise of precision therapies to patients with immune-mediated disease." About BHV-1400BHV-1400 is a potential first-in-class Gd-IgA1 TRAP degrader, rationally designed to leverage the body's natural hepatic clearance mechanisms to selectively target and remove Gd-IgA1, the underlying cause of the IgA nephropathy and IgA vasculitis. BHV-1400 spares IgG, IgA, IgE, and IgM to preserve patient immune protection against bacteria, viruses and parasites. The results of the ongoing Phase 1 study confirm that BHV-1400 produces deep reductions in Gd-IgA1 within hours, is selective, sparing other immunoglobulins, is tunable, and is safe and well-tolerated. About BHV-1300BHV-1300 is a small molecule and potential first-in-class extracellular IgG degrader, rationally designed to leverage the body's natural hepatic clearance mechanisms to selectively target and remove IgG1, IgG2, and IgG4, the underlying cause of many immune-mediated diseases. BHV-1300 spares IgG3 to preserve patient immune protection against bacteria, viruses and parasites. The results of ongoing Phase 1 study confirm that BHV-1300 produces deep reductions in total IgG, is selective, sparing IgG3, is tunable, and is safe and well-tolerated.
