Presents progress and new anticipated milestones across portfolio of more than 10 assets and 6 therapeutic areas. Announces multiple advancements across the MoDETM (molecular degraders of extracellular proteins) platform and the next generation TRAPTM (targeted removal of aberrant protein) degraders, including: IgA Nephropathy (IgAN) program: First-in-human dosing with BHV-1400, a next generation TRAP degrader, achieved rapid, deep, and selective lowering of only aberrant galactose-deficient IgA1 (Gd-IgA1), the antibody causing IgA nephropathy, while sparing normal IgA. This selective and rapid approach to immunoglobulin lowering represents a second-generation therapeutic approach to IgAN, potentially allowing for strong disease control with less acute or long-term safety risks associated with complement inhibition or broad antibody suppression. The first and lowest dose tested (125mg) of BHV-1400 in the ongoing Phase 1 achieved rapid lowering of Gd-IgA1 with a median reduction of 60% within four hours of administration after a single dose. Maximal reduction exceeding 70% was observed within eight hours. Reductions were sustained for days even after a single dose. This rapid reduction of Gd-IgA1 is unprecedented in drugs targeting Gd-IgA1 and could allow for potential indications in situations where rapid Gd-IgA1 lowering could be beneficial in addition to chronic active disease and long-term maintenance. BHV-1400 has been safe and well-tolerated in the Phase 1 study to date and demonstrated no clinically significant changes in innate or adaptive immunity, including white blood cells and immunoglobulins IgG, IgA, IgE, and IgM. There were no clinically significant reductions in albumin, liver function test abnormalities, or increases in cholesterol compared to baseline. No dose limiting toxicities have been observed in the Phase 1 to date and further dose escalation is planned to explore the full range of Gd-IgA1 reductions possible with BHV-1400. A pivotal trial in IgA nephropathy is planned using an accelerated regulatory path forward upon completion of the Phase 1 trial. Peripartum cardiomyopathy (PPCM) program: First-in-human dosing with BHV-1600, a TRAP degrader of β1AR autoantibodies, was initiated and has been well-tolerated to date after the first two dose cohorts without clinically relevant changes in innate or adaptive immunity, including white blood cells and immunoglobulins IgG, IgA, IgE, and IgM. There were no clinically significant reductions in albumin, liver function test abnormalities, or increases in cholesterol compared to baseline. β1AR autoantibodies are thought to cause peripartum cardiomyopathy, a rare form of heart failure that develops at the end of pregnancy or in the months following delivery and in severe cases, can be life-threatening. BHV-1600 has been shown to bind to β1AR autoantibodies in preclinical studies and biomarker levels will be measured in women with PPCM later in development. Completed INTERACT meeting with FDA regarding BHV-1600 in 4Q 2024; gained alignment for the study design to potentially pursue an accelerated approval pathway in PPCM. IgG degrader programs: BHV-1300: Advanced optimized subcutaneous formulation with deep reductions of targeted IgG >60% demonstrated in the lowest dose cohort of the MAD, in line with modeling projections and with differentiated safety profile. There were no clinically significant reductions in IgG3, IgA, IgE, IgM, or albumin, no liver function test abnormalities, nor increases in cholesterol compared to baseline. Phase 1 completing last remaining dose cohorts with the optimized subcutaneous formulation in 1H 2025. Lead indication for BHV-1300 announced in Graves' Disease, a common autoimmune disorder affecting approximately 80 million people globally. Graves' Disease is caused by IgG1 autoantibodies that hyperstimulate the TSH receptor, causing hyperthyroidism can result in the need for surgical removal, chemical ablation of the thyroid, or need for chronic anti-thyroid drugs. Additional programs in rheumatoid arthritis and myasthenia gravis also continue to be pursued with BHV-1300 and 1310. Study May Proceed letter received from FDA for BHV-1310 IND, a novel IgG degrader and Phase 1 initiating in 1H 2025. BHV-1300 and BHV-1310 are similar but will optimize therapeutic targeting and facilitate broader commercial development options. Next generation degrader targets advancing in 2025 include: IgG4 specific degrader, PLA2R autoantibody degrader for membranous nephropathy, pro-insulin autoantibody degrader for type 1 diabetes, and TSH receptor autoantibody degrader as a selective follow-on asset for Graves' Disease.

Biohaven 2025 Portfolio Review and Anticipated Milestones
Biohaven is positioned to achieve significant milestones in 2025 across a broad spectrum of early- and late-stage programs targeting indications with high unmet need:
Molecular Degrader of Extracellular Proteins (MoDE) Platform: Biohaven's novel immune-modulating extracellular degrader platform harnesses selectivity, rapidity, and patient-friendly self-administration to remove disease-causing proteins from the body to potentially treat a wide range of diseases. Biohaven introduced next generation TRAP degraders, which are highly selective, each targeting a specific disease-causing protein for proteolysis. Four INDs for MoDE and next generation TRAP degrader molecules (targeting IgG1, IgG2, IgG4, Gd-IgA1, and β1AR autoantibodies) have been accepted by the FDA in 2024 with several additional investigational agents in development. Three assets have been dosed in Phase 1 trials with the fourth anticipated to be dosed in the first half of 2025.
The first-of-its-kind molecule, BHV-1300 is being developed for the treatment of common immune-mediated diseases, such as Graves' Disease and Rheumatoid Arthritis. With patient-centered design, Biohaven has advanced a proprietary subcutaneous formulation of BHV-1300 and has entered into an agreement with Ypsomed, to develop and manufacture BHV-1300 in an easy-to-use, autoinjector for self-administration. This BHV-1300 proprietary formulation has demonstrated deep and targeted reductions of IgG, with reductions > 60% within four hours and 70% reduction within eight hours in the lowest subcutaneous dose tested in the MAD. Reductions were sustained even after just a single dose administration. Targeted IgG reductions (IgG1, IgG2, and IgG4, over IgG3) have been consistent with projected modeling. Phase 1 dose escalation is completing in 1H 2025, with Graves' Disease Phase 2 trial to initiate mid-year. BHV-1300 was rationally designed to spare IgG3 to preserve host immune defense. The selectivity of BHV-1300 demonstrated in the Phase 1 trial establishes a differentiated safety profile for the treatment of autoimmune disease relative to other IgG-lowering agents and validates the precision of the platform.
BHV-1400 and BHV-1600, currently in Phase 1 clinical trials, represent the next generation TRAP degraders focused on selectively clearing very specific pathogenic antibodies, while sparing healthy immunoglobulin to preserve immune function. TRAP molecules commence a new age of immune-modulating treatments, targeted removal of disease-causing proteins for removal while sparing the normal function of the healthy immune system. Data from the first, and lowest, dose cohort of BHV-1400 demonstrated clear differentiation from competitors in the IgA nephropathy space, with rapid lowering of Gd-IgA1 within four hours and preservation of host immunoglobulins including IgG, IgA, IgE, and IgM. IgA nephropathy is a rare chronic kidney disease affecting young and middle-aged adults that is caused by Gd-IgA1 and leads to kidney failure in up to 40% of patients within 10-20 years.
Taken in total, the selectivity of MoDE and TRAP degraders demonstrated to date refine immune-modulating treatment representing a clear next generation of drug development technology in immunoglobulin and extracellular protein lowering. Existing mechanisms, both pharmaceutical and device (plasmapheresis), broadly reduce immunoglobulins subclasses and/or isotypes, leading to inefficient dosing, safety risks, necessity of procedures, delays in therapy, and potential efficacy impacts. MoDE and TRAP's new paradigm builds off the prior successes of immune modulation, while also providing a novel technology to fine tune therapies for immune-mediated diseases. As described below, the implications and applications of this selective targeting could be multi-organ, multi-disease.
IgA Nephropathy (IgAN) Program: First-in-human dosing with BHV-1400 achieved rapid, deep, and selective lowering of only Gd-IgA1, the aberrant antibody that causes IgA nephropathy, while sparing normal IgA. The first and lowest dose tested (125 mg) of BHV-1400 in Phase 1 achieved rapid lowering of Gd-IgA1 with a median reduction of 60% within four hours of administration. Maximal reduction exceeding 70% was observed within eight hours. Even after just a single dose administration of BHV-1400, reductions in Gd-IgA1 were sustained for days. The rapid reduction of Gd-IgA1 by BHV-1400 is unprecedented in drugs targeting Gd-IgA1 and could allow for potential indications in situations where rapid Gd-IgA1 lowering could be beneficial in addition to chronic active disease and long-term maintenance. The selective and rapid approach to Gd-IgA1 lowering of BHV-1400 represents a second-generation therapeutic approach to IgAN, potentially allowing for effective disease control with less acute- or long-term safety risks associated with B-cell directed therapy, complement inhibitors, or broad immunosuppression. BHV-1400 has been safe and well-tolerated in the Phase 1 study to date and demonstrated no clinically significant changes in innate or adaptive immune systems, including white blood cells and immunoglobulins IgG, IgA, IgE, and IgM, and no clinically significant reductions in albumin, liver function test abnormalities, or increases in cholesterol compared to baseline. There have been no dose limiting toxicities observed in the Phase 1 study and dose escalation continues to explore the full range of Gd-IgA1 reductions possible with BHV-1400. A pivotal trial in IgA nephropathy is planned using an accelerated regulatory path upon completion of the Phase 1 trial. Additional opportunities in situations when rapid Gd-IgA1 reduction could be beneficial may also be feasible given the demonstrated dosing kinetics in the Phase 1 study. Biohaven further expands its renal franchise with the degrader platform, developing several investigational TRAPs for the treatment of immune-mediated renal disease, including a TRAP degrader to target PLA2R autoantibodies for the treatment of membranous nephropathy among others.

Peripartum cardiomyopathy (PPCM) program: First-in-human dosing with BHV-1600 has been safe and well-tolerated to date after two dose cohorts without clinically relevant changes in innate or adaptive immune systems, including white blood cells and immunoglobulins IgG, IgA, IgE, and IgM, and no clinically significant reductions in albumin, liver function test abnormalities, or increases in cholesterol compared to baseline. β1AR autoantibodies are thought to cause peripartum cardiomyopathy, a rare form of heart failure with no approved therapy that occurs at the end of pregnancy or following delivery and in severe cases, can be life-threatening. BHV-1600 has been shown to bind to β1AR autoantibodies in preclinical studies and biomarker levels will be measured in women with PPCM later in development. Completed INTERACT meeting with FDA regarding BHV-1600 in 4Q 2024 and gained alignment for the study design to potentially pursue an accelerated approval pathway in PPCM, a rare autoimmune life-threatening disease with no approved therapy.

Tova Gardin , M.D., M.P.P, Biohaven Chief Translational Officer, reflected on the recent results from the MoDE degrader platform, "With the advancements across our degrader platform, including the highly selective TRAP molecules, Biohaven inaugurates a new age of immune-modulating treatment – one which opens the potential of treating the pathogenesis of disease with precision to restore healthy homeostasis. The results of BHV-1400 from the first and lowest SAD cohort highlight the speed, precision, and patient-centered innovation that drives development of each of our molecules. Lowering Gd-IgA1 by 60% within hours of dose administration, BHV-1400 realizes the precision possible with MoDE degraders: The possibility of selectively degrading the pathogenic driver of disease, leaving host immunity unperturbed. Innovation extends across the MoDE platform, with new programs launched for the treatment of Graves' Disease, peripartum cardiomyopathy, and other selective TRAP degraders advancing towards development candidate nominations to potentially treat membranous nephropathy, IgG4-mediated disease, and diabetes."
BHV-2100: First-in-clinic, oral, selective TRPM3 antagonist that offers a novel, non-addictive treatment for migraine and neuropathic pain.

Taldefgrobep alfa: Taldefgrobep is a novel myostatin inhibitor that is optimized to block both myostatin and activin A signaling, two key regulators of muscle and fat metabolism. Biohaven is studying taldefgrobep in a global Phase 3 expansion study in Spinal Muscular Atrophy (SMA), as an adjunctive therapy to enhance muscle mass and function in patients treated with standard-of-care therapies. Analyses of prespecified subgroups by race and ethnicity demonstrated that the largest study population (87% Caucasian; n=180) showed clinically meaningful improvements on the MFM-32 at all timepoints, including Week 48, compared to the corresponding placebo+SOC group (p < 0.05), though the overall primary endpoint was not met. Robust target engagement (myostatin reduction) and beneficial impacts on body composition parameters (fat mass, lean muscle mass, and bone density) were noted, offering a potential paradigm shift in the treatment of obesity with opportunity to improve quality of weight loss; lower total body weight by specifically reducing fat mass while also preserving or increasing lean muscle mass.
Upcoming milestones in the taldefgrobep program include:
Expected FDA meeting to discuss SMA registrational path in 1H 2025. Initiate taldefgrobep Phase 2 study in obesity in 1H 2025.
BHV-8000: BHV-8000 is a highly selective, oral, brain-penetrant, selective TYK2/JAK1 inhibitor with broad potential for neurodegenerative and neuroinflammatory disorders. In the Phase 1 SAD/MAD study in healthy participants, BHV-8000 was generally safe and well-tolerated while producing significant reductions in inflammatory biomarkers relative to placebo. Target indications for BHV-8000 include Parkinson's disease, Alzheimer's disease, prevention of amyloid-related imaging abnormalities (ARIA), and multiple sclerosis (MS). In 2024, Biohaven completed interactions with FDA enabling registrational programs for Parkinson's disease and the prevention of ARIA.
Upcoming milestones in the BHV-8000 program include:
Initiate BHV-8000 Phase 2/3 study in Parkinson's disease in 1H 2025 Advance Alzheimer's, MS and ARIA programs in 2025.
Oncology antibody drug conjugate (ADC) portfolio:
BHV-1510 (Trop2 ADC): Preliminary data from the initial Phase 1 study dosing cohorts of BHV-1510 have demonstrated promising clinical activity, including tumor shrinkage, with a tolerable safety profile of the novel topoisomerase 1 (TopoIx) payload. The Phase 1/2 study of BHV-1510 is progressing with robust enrollment in dose escalation and optimization, both as monotherapy and in combination with the anti-PD1 monoclonal antibody Libtayo® (cemiplimab-rwlc) through a clinical supply agreement with Regeneron.
Preclinically, TopoIx has shown increased immunogenic cell death and synergistic activity when combined with anti-PD1/L1 checkpoint inhibitors, and a differentiated nonclinical toxicity profile; Clinical activity has been seen across dose cohorts tested to date, including the lowest dose tested of 2mg/kg Q3W; Early PK data demonstrates a stable ADC with very low serum concentrations of free payload; Preliminary safety data demonstrates a favorable profile, with no payload-associated interstitial lung disease, gastrointestinal toxicities, or significant hematological toxicities observed in early cohorts. The main toxicity observed thus far in Phase 1 study has been stomatitis, an expected on-target Trop2 class toxicity that has been manageable; Combination cohorts of BHV-1510 with Libtayo® have initiated.
Based on these encouraging early results, Biohaven has entered into an expanded collaboration agreement with GeneQuantum, which provides broad target exclusivity for up to 18 ADC targets incorporating the novel topoisomerase 1 inhibitor (TopoIx) payload.
Biohaven has incorporated the TopoIx payload into its next clinical-stage investigational agent, BHV-1530. BHV-1530 is an FGFR3-directed ADC with potential indications in cancers driven by FGFR3 alterations and/or upregulated FGFR3 protein expression, including urothelial cancers and other solid tumors. While FGFR3 has been clinically validated as a target in oncology, there are no other FGFR3 ADCs currently in clinical development. Biohaven retains global rights for BHV-1530 under the agreement via an exclusive license with GeneQuantum and Aimed Bio. The US IND has been opened, and a first-in-human study for solid tumors is planned for 1H 2025.
In addition, Biohaven today announced a multi-target collaboration with Merus, an oncology-focused biotechnology company developing innovative, multi-specific (Biclonics® and Triclonics®) antibodies. This collaboration will co-develop three programs encompassing highly differentiated next generation dual-targeted bispecific ADCs leveraging Biohaven's proprietary conjugation and payload technologies along with Merus' leading Biclonics technology platform.
Together, the announced milestones and collaborations represent a significant expansion of Biohaven's ADC portfolio, positioning the Company with potential to deliver highly differentiated therapeutics and address significant unmet needs in Oncology.
Nushmia Khokhar , M.D., Biohaven Chief Medical Officer of Oncology, commented, "These are exciting times for Biohaven's oncology pipeline as we are well-positioned to introduce differentiated, next generation ADCs to the clinic. The early Phase 1 data with BHV-1510 is promising, showing not only signs of clinical activity but also minimal toxicities related to the free payload. This affirms the advantages of our conjugation technology, which provides high ADC stability. The distinct profile of the novel TopoIx payload, and its potential to synergize with checkpoint inhibitor therapy, could significantly benefit patients across various cancer types. Furthermore, our collaboration with Merus and the expanded partnership with GeneQuantum—utilizing the TopoIx payload for multiple targets—demonstrate the potential of Biohaven's upcoming innovative ADCs. This includes dual-targeting ADCs, which are exciting for their potential to address challenges like tumor heterogeneity and delivery of stable ADCs with an improved therapeutic index."
Upcoming milestones in the oncology program include:
Interim Phase 1 data with BHV-1510 and dose optimization as monotherapy and combination therapy with Libtayo® in epithelial tumors in 2025. Initiate Phase 1 trial of BHV-1530 in 1H 2025. Advance Merus collaboration ADCs (undisclosed targets) and TopoIx ADCs in 2025.
