Biohaven 2026 Portfolio Review and Anticipated Milestones
Biohaven is positioned to achieve significant milestones in 2026 across key programs targeting indications with high unmet need. Throughout its clinical-stage portfolio, combined with its innovative discovery engine, the company is advancing a broad range of innovative medicines that represent paradigm-shifting treatment options.
Novel Degrader Platforms: Biohaven Raises the Bar in Precision Immunology
Biohaven is pioneering scientific innovation in extracellular protein degradation, a transformational therapeutic approach for autoimmune diseases that focuses on the precise targeting and selective removal of disease-causing proteins. Based upon the groundbreaking work from the Spiegel Chemistry Lab at Yale University and exclusively licensed by Biohaven, the company's MoDE and TRAP degrader platform offers selectivity, speed, and patient-friendly self-administration to remove disease-causing extracellular proteins from the body to potentially treat a wide range of diseases.
As part of an initiative to further advance and accelerate next-generation degrader development, Biohaven also announced entering into an memorandum of understanding with the King Abdullah University of Science and Technology (KAUST) to collaborate on discovery efforts and leverage the University's technology capabilities including strengths in its Smart Health initiatives, generative AI, and supercomputing.
BHV-1400: Next-Generation TRAP Degrader for IgA Nephropathy (IgAN)
Biohaven's highly selective next-generation TRAP degraders target a specific disease-causing protein for degradation after removal from the circulation. The company's potential first-in-class TRAP degrader, BHV-1400, brings precision immunology to the treatment landscape of IgA nephropathy the most common primary glomerulonephritis worldwide. IgAN is caused by the excess production of galactose-deficient IgA1 (Gd-IgA1) which is bound by autoantibodies and forms complexes that deposit in the glomerular mesangium triggering a profibrotic and proinflammatory cascade, ultimately leading to renal failure.
The first clinical experience with BHV-1400 underscores its paradigm-shifting potential to selectively remove only aberrant Gd-IgA1, the disease-causing species in IgA nephropathy, while sparing normal IgA. First-in-patient dosing with BHV-1400, a next-generation TRAP degrader, achieved selective lowering of Gd-1gA1 within hours, translating to hematuria resolution, deep reductions in proteinuria, and eGFR improvements within weeks of dosing.
The first patient dosed, a young woman with early disease, normal baseline eGFR and chronic hematuria experienced rapid reductions in Gd-IgA1 associated with complete resolution of chronic hematuria and improvement in symptoms of fatigue within weeks of dosing. The second patient dosed, a man with late-moderate-to-severe loss of kidney function as evidenced by decreased baseline eGFR, experienced rapid reductions in Gd-IgA1 associated with robust reductions in proteinuria of greater than
In the ongoing Phase 1, BHV-1400 achieved rapid lowering of Gd-IgA1 with a mean reduction of >
BHV 1300: MoDE Degrader with Potential to Transform Care Across Multiple IgG Mediated Diseases
BHV-1300, Biohaven's lead MoDE degrader, is currently in development for Graves' disease, an IgG1-mediated autoimmune disease caused by autoantibodies that hyperstimulate the TSH receptor, causing hyperthyroidism and requiring surgical removal or chemical ablation of the thyroid or the chronic administration of anti-thyroid drugs. BHV-1300 has shown the potential for best-in-class reductions of IgG, with maximum reductions up to an
Results from the first-in patient clinical experience with BHV-1300 also showed that it induced complete suppression of pathogenic TSH receptor-stimulating antibodies with normalization of previously elevated thyroid hormones within weeks after dosing. There were no clinically significant reductions in IgG3, IgA, IgE, IgM, or albumin, nor increases in cholesterol compared to baseline. Clinical findings to date position BHV-1300 for pivotal study initiation in Graves' disease in 2026, as well as additional follow-on studies in other autoimmune diseases where its therapeutic pan-IgG depletion capability is expected to have significant potential.
Biohaven Discovery Engine for Next-Generation Degraders
With proof-of-concept now established in patients for the first clinically validated extracellular protein degrader platform, Biohaven's discovery engine is prepared to advance next-generation MoDE and TRAP degraders as lead programs, including:
- BHV-1420, a PLA2R autoantibody specific TRAP degrader, for membranous nephropathy;
- BHV-1450, a IgG4 specific MODE degrader, for potential indications including pemphigus vulgaris and myasthenia gravis with anti-MuSK antibodies;
- BHV-1440, a TSHR autoantibody specific TRAP degrader, as the next-generation of immune therapy for Graves' disease and thyroid eye disease;
- BHV-6500, a proinsulin and insulin autoantibody TRAP degrader, for type 1 diabetes;
- BHV-1490, an IgM MoDE degrader for cryoglobulinemia, Waldenstrom's macroglobulinemia and IgM neuropathy;
- BHV-1310, a next generation IgG MoDE degrader, for management of rare IgG-mediated indications;
- BHV-1600, a beta-1 adrenergic receptor autoantibody degrader, for cardiomyopathy; and,
- Multiple undisclosed degrader targets in early discovery development.
Epilepsy Program: Revolutionizing the Treatment of Epilepsy with a Modern Kv7 Activator
Opakalim is a next-generation, selective Kv7 activator, targeting a clinically validated mechanism of action for the treatment of epilepsy. It is highly differentiated from ezogabine, a first-generation non-selective Kv7 activator previously approved for the treatment of focal seizures, and ezogabine analogs in development. Importantly, opakalim does not exhibit the GABA receptor activity seen with ezogabine and other antiseizure medicines (ASMs), which contribute to central nervous system (CNS) adverse effects and their poor tolerability in the clinic. Opakalim is being developed to address the significant unmet medical need that exists for novel ASMs having a favorable tolerability profile, especially those with mechanisms of action that are complementary to currently available ASMs.
Biohaven is currently conducting two Phase 2/3 randomized, double-blind, placebo-controlled studies (NCT06132893 and NCT06309966) comparing the efficacy of opakalim to placebo as an adjunctive therapy for refractory focal onset epilepsy, as well as an open-label extension (OLE) study (NCT06443463) to evaluate the long-term efficacy and safety of opakalim in participants who completed either parent study.
Review of data from the ongoing open-label clinical trial experience with opakalim in focal epilepsy support the potential for opakalim to achieve compelling efficacy and to deliver a highly favorable and differentiated safety profile. Open-label treatment with opakalim demonstrated clinically meaningful reductions in seizure frequency compared to the pretreatment baseline observation period prior to randomization. Specifically,
These preliminary observations support the paradigm-shifting potential of opakalim to achieve antiseizure efficacy with a highly favorable and differentiated tolerability profile compared to other approved ASMs and those in development.
- Pivotal topline results for opakalim in the treatment of focal epilepsy are expected in 2026.
Obesity Program: Targeting High Quality Weight Loss
Taldefgrobep alfa is Biohaven's novel inhibitor of the myostatin-activin signaling pathway with the potential to achieve high quality weight loss in people living with obesity.
Biohaven initiated a taldefgrobep Phase 2 proof-of-concept study in obesity during the fourth quarter of 2025 (NCT07281495). This randomized, double-blind, placebo-controlled, 24-week, dose-ranging study is evaluating the efficacy and tolerability of once-weekly and once-monthly taldefgrobep as monotherapy, via self-administered autoinjector, in adults living with overweight and obesity. Approximately 150 participants will be enrolled. The primary outcome measure is percent change in total body weight from baseline to Week 24.
Taldefgrobep's differentiated mode of action targets fat reduction, builds muscle, and increases bone density.
In the clinic, taldefgrobep has demonstrated beneficial changes in fat mass and lean mass in non-obese populations, including healthy adult participants in a Phase 1 study. Participants who received taldefgrobep once-weekly realized significant reductions in total body fat mass (>
Taldefgrobep has an established safety profile that is well-suited for an indication in overweight and obesity. It has been previously evaluated in >700 clinical trial participants across 5 completed studies and an ongoing Phase 3 trial in spinal muscular atrophy. Throughout its clinical development, taldefgrobep has been well tolerated, with rates of muscle and gastrointestinal adverse events comparable to placebo.
- Phase 2 topline results for taldefgrobep in the treatment of obesity are expected in 2026.
Advancement of Key Next Generation ADC Oncology Programs
BHV-1510 (Trop2 ADC): Preliminary Phase 1 results for BHV-1510 showed encouraging clinical activity with confirmed responses and a differentiated safety profile demonstrating clinical proof of principle with Biohaven's novel topoisomerase 1 (TopoIx) payload. In a pretreated population of participants with advanced/metastatic cancer, the majority with prior PD-(L)1 treatment, BHV-1510 2.5 mg/kg IV Q3W plus cemiplimab resulted in a confirmed objective response rate of
Biohaven also announced the successful initiation of subcutaneous administration with BHV-1510, as the first and only Trop2 ADC in clinic with the potential for subcutaneous delivery. In the first patients, early data showed bioavailability in the predicted range with tumor shrinkage in first patient dosed. Subcutaneous delivery may offer several advantages over intravenous infusion, including a more patient-friendly experience and rapid administration (minutes vs hours). In addition, subcutaneous dosing may provide an optimized pharmacokinetic profile with lower Cmax and more stable exposure, which may support improved safety and efficacy.
BHV-1530 (FGFR3 ADC): Biohaven also provides an update of the ongoing first-in-human clinical trial of BHV-1530, a potential first-in-class FGFR3-directed ADC that also leverages the proprietary TopoIx payload. In the initial cohorts, no dose-limiting toxicities were observed, and no safety signals have emerged. Early tumor reduction was seen in a patient with an FGFR3 mutation as dosing enters the predicted efficacious range. The pharmacokinetic profile indicates a highly stable ADC, consistent with Biohaven's next-generation platform technology. FGFR3 is a promising therapeutic target in patients with genetic alterations or overexpression including urothelial cancer and may also be relevant across other solid tumors with high unmet need.
Progress across portfolio of clinical and next-generation discovery programs:
Patient enrollment continues in pivotal Phase 2/3 clinical trial in early Parkinson's disease with brain-penetrant TYK2/JAK1 inhibitor, BHV 8000.
