Retaining IgG3 allows for preservation of key host immune defense against viruses, bacteria and parasites.\n\nBHV-1300 has been safe and well tolerated across the ongoing Phase 1 studies with subcutaneous doses now administered up to 2000 mg.\n   \nMost 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.\nThere were no clinically significant increases in ALT/AST or bilirubin, no clinically significant reductions in albumin and no clinically significant increases in cholesterol compared to placebo over the 4-week dosing period.\nThere were no clinically significant reductions in other immunoglobulins including IgG3, IgA, IgE, or IgM compared to baseline.\n\nBased upon the rapid and deep reductions of total IgG observed with subcutaneous BHV-1300, Biohaven reiterates its plans to initiate a Phase 2 study in Graves' disease in mid-2025. Additional follow-on studies in other autoimmune diseases will be pursued.\n   \nGraves' disease is a common autoimmune disorder affecting 3 million individuals in the US and 80 million people globally. Graves' disease is caused by IgG1 autoantibodies that hyper-stimulate the thyroid stimulating hormone (TSH) receptor. The rational design of BHV-1300 enables degradation of the autoantibodies causing Graves' disease, known to be of the IgG1 subclass, while maintaining host immunity.\n\nTRAPTM degraders, Biohaven's next generation \"targeted removal of aberrant protein\" degraders from the MoDE platform also continue to advance through Phase 1 with multiple doses completing the SAD/MAD cohorts including BHV-1400, a selective Gd-IgA1 degrader being developed for IgA nephropathy, and BHV-1600, a β1AR autoantibody degrader for cardiomyopathy. Additional details and data regarding these TRAP degraders will be presented at an upcoming conference.\n\nNEW HAVEN, Conn., March 3, 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 BHV-1300, its potential first-in-class IgG1,2,4 selective degrader, in achieving rapid and deep reductions in total IgG, advancing a novel and transformative MoDE platform molecule for the potential treatment of autoimmune disease.\n\n  \n\nIn the four-week Phase 1 study, subcutaneously administered BHV-1300 at a dose of 1000 mg weekly achieved rapid, deep and sustained reductions in total IgG of up to 84%, with a median reduction of 80% (Figure 1). Reductions occurred within hours of each dose, were progressive, and were sustained compared to baseline over the four-week period.\nTova Gardin, MD, MPP, Chief Translational Officer at Biohaven, commented, \"BHV-1300 has demonstrated remarkable efficacy in deep lowering of total IgG, leveraging the groundbreaking technology of the MoDE platform, to potentially revolutionize treatment of patients with autoimmune disease. Biohaven's unique extracellular degrader technology leverages the body's natural hepatic clearance mechanism to remove targeted antibodies contributing to disease and promises to usher in a new era of tunable, selective and self-administered immune therapy.\"\nBHV-1300 was 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 compared to placebo. There were no clinically significant reductions in IgG3, IgA, IgE, or IgM compared to baseline. Most 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. The Phase 1 study is ongoing with plans to continue to escalate multiple doses to explore the full range of targeted IgG lowering possible with this technology to customize an ideal treatment approach for different disease indications.\nBiohaven's MoDE technology used in developing BHV-1300 was licensed from Yale University stemming from groundbreaking chemistry work in the Spiegel Lab. Yale Professor David Spiegel, MD, PhD, inventor of the MoDE technology and the first to patent the use of targeted extracellular protein degraders that utilize the asialoglycoprotein receptor (ASGPR), commented, \"This remarkable demonstration in humans of rapid, deep and sustained reductions of targeted IgG removal with BHV-1300 is a breakthrough and a testament to the scientific advancements that can be accomplished by innovative academic and industry collaborations. BHV-1300 has catapulted the field of extracellular degraders forward and promises to shift the paradigm for the treatment of individuals living with immune-mediated diseases. It is truly an honor to be able to collaborate with the team at Biohaven on this exciting journey.\"\nBHV-1300 is differentiated from monoclonal antibodies targeting FcRn inhibition, offering a novel and selective approach to treat autoimmune causes of disease, while enabling patients to maintain immune protection against infection through preservation of IgG3 (Figure 2). IgG degradation with BHV-1300 is deep and tunable, capable of achieving remarkable depth of IgG lowering, and with refinement in degradation depth feasible through titration of dose level and frequency. It is designed for self-administration via an easy-to-use and patient-friendly autoinjector through an ongoing partnership with Ypsomed AG. \nDr. Gardin added, \"This data released today supports advancing BHV-1300 as a potential first-in-class, small molecule approach to treating Graves' disease, a common autoimmune disease that is currently treated with surgery, ablation or anti-thyroid drugs. Our innovative approach unifies cutting-edge science with renewed understanding of disease pathology, to advance a potential first and best-in-class therapeutic for the treatment of Graves' disease. Based on the PK/PD and safety profiles exhibited in the ongoing Phase 1 study, we are thrilled to advance BHV-1300 forward as we aim to disrupt the current treatment paradigm in Graves' disease and potentially revolutionize the treatment of this disease which impacts millions of patients across the world.\"\nGraves' disease is an autoimmune condition that impacts 3 million individuals in the US and 80 million people worldwide. In Graves' disease (Figure 3), IgG1 autoantibodies mimic TSH, binding the TSH receptor in the thyroid and stimulating excess production of thyroid hormones. Graves' disease impacts every organ system, causing symptoms such as cardiac arrhythmias, anxiety, heat intolerance, weight loss, changes in appetite and bowel movements and shortness of breath, in addition to causing related conditions of thyroid eye disease and infiltrative dermopathy. A considerable unmet need exists for improved therapeutic options that target the underlying autoimmune etiology of disease and do not result in permanent hypothyroidism or bear risk of fatal agranulocytosis, hepatotoxicity and teratogenicity. While conventional treatments for Graves' disease, including thyroid removal or ablation and antithyroid drugs, have not changed in 70 years, scientific understanding of immunobiology has advanced considerably, enabling the development of BHV-1300, a precision therapeutic that targets the underlying IgG1 autoantibodies causing the disease.\nAbout 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 the disease. BHV-1300 spares IgG3 to preserve patient immune protection against bacteria, viruses and parasites (Figure 2). The results of the 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.\nAbout Biohaven Biohaven is a biopharmaceutical company focused on the discovery, development, and commercialization of life-changing treatments in key therapeutic areas including immunology, neuroscience and oncology.
